What Covid Means for the Athlete’s Heart

For sports fans across the country, the resumption of the regular sports calendar has signaled another step toward post-pandemic normality. But for the athletes participating in professional, collegiate, high school or even recreational sports, significant unanswered questions remain about the aftereffects of a covid infection.

This story also ran on ESPN. It can be republished for free.

Chief among those is whether the coronavirus can damage their hearts, putting them at risk for lifelong complications and death. Preliminary data from early in the pandemic suggested that as many as 1 in 5 people with covid-19 could end up with heart inflammation, known as myocarditis, which has been linked to abnormal heart rhythms and sudden cardiac death.

Screening studies conducted by college athletic programs over the past year have generally found lower numbers. But these studies have been too small to provide an accurate measure of how likely athletes are to develop heart problems after covid, and how serious those heart issues may be.

Without definitive data, concerns arose that returning to play too soon could expose thousands of athletes to serious cardiac complications. On the other hand, if concerns proved overblown, the testing protocols could unfairly keep athletes out of competition and subject them to needless testing and treatment.

“The last thing we want is to miss people that we potentially could have detected, and have that result in bad outcomes — in particular, the sudden death of a young athlete,” said Dr. Matthew Martinez, director of sports cardiology at Atlantic Health’s Morristown Medical Center in New Jersey and an adviser to several professional sports leagues. “But we also need to look at the flip side and the potential negatives of overtesting.”

With millions of Americans playing high school, college, professional or master’s level sports, even a low rate of complications could result in significant numbers of affected athletes. And that could prompt a thorny discussion of how to balance the risk of a small percentage of players who could be in danger against the continuation of sports competition as we know it.

Limited Impact on Pro Sports

Data released from professional sports leagues in early March provided at least some reassurance that the problem may not be as great as initially feared. Pro athletes playing football, men’s and women’s basketball, baseball, soccer and hockey were screened for heart problems before returning from covid infections. The players underwent an electrical test of their heart rhythms, a blood test that checks for heart damage and an ultrasound exam of their hearts. Out of 789 athletes screened, 30 showed some cardiac abnormality in those initial tests and were referred for a cardiac MRI to provide a better picture of their heart. Five of those, less than 1% of athletes screened, showed inflammation of the heart that sidelined them for the remainder of their seasons.

The researchers compiling the data did not name the players, although some have disclosed their own diagnoses. Boston Red Sox pitcher Eduardo Rodríguez returned to the mound this spring after missing the 2020 season following his covid and myocarditis diagnoses. Similarly, Buffalo Bills tight end Tommy Sweeney was close to returning from a foot injury when he was diagnosed with myocarditis in November.

In the college ranks, many assumed Keyontae Johnson — a 21-year-old forward on the University of Florida men’s basketball team who collapsed on the court in December, months after contracting covid — might have developed myocarditis. The Gainesville Sun reported that month he had been diagnosed with myocarditis, but his family issued a statement in February saying the incident was not covid-related and declined to release additional details.

Consequences Still Unclear

Doctors still don’t know how significant those MRI findings of myocarditis may be for athletes. Tests looking for rare medical events often generate more false positives than true positives. And without comparing the results with those of athletes who didn’t have covid, it is hard to determine what changes to attribute to the virus — or what may just be an effect of athletic training or other causes.

Training significantly changes athletes’ hearts, and what might look concerning in another patient could be perfectly normal for an elite athlete. Many endurance athletes, for example, have larger than average left ventricles and pump out a lower percentage of blood with each contraction. That would be a warning sign for patients who aren’t highly trained athletes.

“You can definitely have what we call the gray zone, where extreme forms of athletic cardiac remodeling can actually look a little bit like pathology,” said Dr. Jonathan Kim, a sports cardiologist at Emory University in Atlanta. “Covid has introduced a new challenge to this. Is it because they’re a cross-country runner or is it because they just had covid?”

Moreover, myocarditis is generally diagnosed based on symptoms — chest pain, shortness of breath, heart muscle weakness or electrical dysfunction — and then confirmed by MRI. It isn’t clear whether MRI findings that look like myocarditis in the absence of those symptoms are just as concerning.

“They have normal physical exams. They have normal cardiograms. Nothing else is going on,” said Dr. Robert Bonow, a cardiologist at Northwestern University and editor of JAMA Cardiology. “But when you order an MRI as part of a research study, you start seeing very subtle changes, because the MRI is very sensitive.”

Were they finding “abnormalities” simply because they were looking? Even in patients who die of covid, the rate of myocarditis is very low, Bonow said.

“So what’s going on with the athletes? Is it something related to the fact that they had an infection, or is it something which is very nonspecific, related to covid but not damage to the heart?” he said. “There’s still a great deal of uncertainty.”

Sports cardiologists involved in the pro sports data collection and in writing screening guidelines for athletes said the fact that players were able to resume their seasons without serious heart complications suggests the initial concern was overblown. Of the players who had mild or asymptomatic cases of covid, none was ultimately found to have myocarditis, and none experienced ongoing heart complications through 2020. Many completed their 2020 season and have already started their next one.

“We overcalled it,” Martinez said. “It shows what our guidelines reflected: The prevalence of cardiac disease in this condition is unusual in the athletic population.”

Falling Through the Cracks

Those screening guidelines, published by a group of leading sports cardiologists in October, call for cardiac tests only for athletes with moderate or severe covid symptoms. Athletes with asymptomatic cases or those with mild symptoms that have gone away can return to play without the additional testing. The National Federation of State High School Associations and the American Medical Society for Sports Medicine have put out similar guidelines for high school athletes.

But that approach would not flag players such as Demi Washington.

Washington, a 19-year old sophomore on Vanderbilt’s women’s basketball team, had a rather mild case of covid. She had shared a meal with two teammates, one of whom later turned out to be infected. Seven days into a two-week quarantine in a hotel off campus, Washington also tested positive, and had to isolate with a stuffy nose for an additional 10 days. She waited for her symptoms to get worse, but they never did.

“It felt like allergies,” she said.

But when her symptoms cleared and she returned to practice, the university required her to undergo several tests to ensure the virus had not affected her heart. The initial tests raised no concerns. An MRI, though, showed acute myocarditis.

Her season was over, but, more importantly, Washington, an athlete in prime physical condition, faced the possibility of losing her life. She learned about Hank Gathers, a 23-year-old Loyola Marymount basketball star who collapsed during a game in 1990 and died within hours. His autopsy confirmed an enlarged heart and myocarditis.

“That really put me on the edge of my seat,” Washington said. “I was like, ‘OK, I have to take this seriously, because I don’t want to end up like that.’”

For months, she had to keep her heart rate under 110 beats per minute. Before, she ran 5 miles a day. With the myocarditis diagnosis, she had to wear a heart monitor, and even a brisk walk could push her above that threshold.

“One time I was walking to the gym and I might have been walking a little fast,” Washington recalled. “My chest got really, really tight.”

By mid-January, however, another MRI showed the inflammation had cleared, and she has since resumed working out.

“I’m so grateful that Vanderbilt does the MRI, because without it, there’s no telling what could have happened,” she said.

She wondered how many other athletes have been playing with myocarditis and didn’t know it.

Cases like Washington’s raise questions about how aggressively to screen. Her condition was found only because Vanderbilt took a much more conservative approach than that recommended by current guidelines: It screened all athletes with cardiac MRIs after they had covid, regardless of the severity of their symptoms or their initial cardiac tests.

Of the 59 athletes screened post-covid, the university found two with signs of myocarditis. That’s just over 3%.

“Is the current rate of myocarditis that we’re seeing high enough to warrant ongoing cardiovascular screening?” asked Dr. Daniel Clark, a Vanderbilt sports cardiologist and lead author of an analysis of the school’s screening efforts. “Five percent is too much to ignore, in my opinion, but what is our societal threshold for not screening highly competitive athletes for myocarditis?”

Even though myocarditis is rare, studies have found that noncovid-related myocarditis causes up to 9% of sudden cardiac deaths among athletes, said Dr. Jonathan Drezner, director of the University of Washington Medicine Center for Sports Cardiology, who advises the NCAA on cardiac issues. Thus covid adds a new risk. The NCAA alone reports more than 480,000 athletes. To provide a sense of scale: If all of them got covid and even 1% were at risk of heart problems, that’s 4,800 athletes.

Waiting for More Data

Doctors are now waiting for the release of data pooled from thousands of college athletes screened after having covid last year. The American Heart Association and the American Medical Society for Sports Medicine have created a national registry to track covid cases and heart disease in NCAA athletes, with more than 3,000 athletes enrolled, while the Big Ten conference is running its own registry.

That registry data may eventually help parse who is most at risk for heart complications, target who needs to be screened and improve the reliability of the tests. Doctors may discover that some symptoms are better indicators of risk than others. And down the road, genetic testing or other types of tests could identify who is most vulnerable.

But will smaller schools have the resources and know-how to screen all their athletes?

“How about all the junior colleges, all the Division III programs, the Division II programs?” Martinez said. “A lot of them are saying, ‘Look, forget it. If we have do all this extra testing, we can’t do it.’”

He said the new pro sports data should reassure those colleges and even high schools, because the vast majority of young, healthy athletes who contract covid generally have mild or asymptomatic infections, and won’t need further testing.

The same guidelines apply to recreational athletes. Those with mild or asymptomatic covid can slowly resume exercising once their symptoms resolve without much concern. Those with moderate or severe cases should talk to their doctors before returning to sports.

Concerns for Small Schools

Large, wealthy universities like Vanderbilt have cutting-edge medical facilities with the resources and expertise to properly interpret cardiac MRIs. Smaller schools could struggle to get their athletes screened.

“There’s only a small number of centers around the country that have the true expertise to be able to effectively do cardiac MRIs on athletes,” said Dr. Dermot Phelan, a sports cardiologist with Atrium Health in Charlotte, North Carolina. “And the reality is that those systems are already stretched trying to deal with normal clinical data. If we were to add a huge population of athletes on top of that, I think we would stretch the medical system significantly.”

Some schools with limited resources for testing could decide to bench athletes recovering from moderate or severe covid rather than risk a devastating event. Others could allow athletes to resume playing once they’ve recovered, and then monitor them for signs of cardiac complications. Many NCAA schools added automated external defibrillators after Gathers’ death in case an athlete collapses during a game or practice.

“You think about all the 100,000 high school athletes out there whose parents are concerned: Do they even have access to anyone who knows something about this? On the other hand, they’re younger people who don’t get really sick with covid,” said Dr. James Udelson, a cardiologist with Tufts Medical Center in Boston. “There’s a concern about how much we don’t know.”

Legal Issues

Some schools may also worry about the liability of allowing players to return after a covid infection if they can’t get the proper cardiac screening.

“No matter what precautions a college or university takes in that regard, they can always be sued,” said Richard Giller, an attorney with the Pillsbury Winthrop Shaw Pittman law firm in Los Angeles. “The real question is, do they have liability? I think that’s going to depend on a number of factors, not the least of which is who recommended that student athletes who contracted covid-19 return to play.”

He recommends that colleges not rely solely on doctors affiliated with the university but have student athletes see their own private physicians to make return-to-play decisions. Teams may also ask players to sign waivers to the effect that if they return to play after a covid infection, they might face cardiac complications.

Some colleges asked students to sign waivers absolving the school if a player contracted covid. But the NCAA ruled that schools couldn’t make those waivers a requirement to play.

Doctors don’t know what might happen over the long run. With barely a year’s worth of experience with covid, it’s not clear whether the myocarditis seen on MRIs will resolve quickly, or whether there might be lingering effects that cause complications years later.

That leaves many concerned about what we still don’t know about covid and the athlete’s heart, as well as the handful of cases that might elude detection.

“You can take a cohort of athletes and put them through every single cardiac test and come out the other end, and one of them will die someday,” Phelan said. “The reality is there’s nothing we can do to be 100% guaranteed.”

Why do we perform an Ultrasound

An ultrasound scan is a medicinal test that utilizes high-frequency sound waves to catch live pictures from within your body. It's otherwise called Sonography. The basic principle behind this technology is similar to that used by sonar and radar, which enable the military to identify planes and ships. An ultrasound helps the physician to recognize and identify the issues with organs, vessels, and tissues without expecting to make a cut. In contrast to other imaging procedures, ultrasound utilizes no radiation. Thus, it's the favored technique for examination of pregnant mothers.Why do we perform an Ultrasound?A great many people relate ultrasound filters with pregnancy. These outputs can give a hopeful mother the principal perspective of her unborn child. In reality, ultrasound can be used for examination of many other body parts. Your specialist may arrange an

ultrasound in case you're having pain, swelling, or different indications that require an inner look of your organs. An ultrasound can give you an inner view of the:

Bladder

brain (in infants)

eyes

gallbladder

kidneys

liver

ovaries

pancreas

spleen

thyroid

testicles

uterus

blood vessels

Ultrasound also helps surgeons’ movements by guiding them through the intricate areas of the body during certain medical procedures, such as biopsies.Key points to keep in mind before and during the examHere we have mentioned a few of the precautions that you must follow before going for an ultrasound at Radiology Center at Harding, Morristown, NJ:

Your specialist may instruct you to fast for eight to 12 hours before your ultrasound, particularly if your mid-region is being inspected. Undigested food can obstruct the sound waves, making it troublesome for the expert to get a reasonable picture.

For an examination of the gallbladder, liver, pancreas, or spleen, you might be advised to eat a meal without fat a night prior to your test and undergo fasting until the entire process is completed. However, you can keep on drinking water and accept any prescriptions as suggested. For different examinations, you might have to drink a great deal of water and to hold your pee with the goal that your bladder is full and a better picture can be captured.

Make sure that you keep your physician informed about any medication or therapy which you are going through. It is essential that you ask any questions in case of a doubt before going for the procedure. This helps to maintain transparency between the patient and the doctor.

How is the ultrasound

Ultrasound is a kind of medical test, which uses sound waves of high frequency to captivate the images of internal parts of the body. Ultrasound is also termed as sonography. An ultrasound is used by the doctors to study the problems of the internal parts of the body such as vessels, organs, tissues, and many more. There is no need to make a cut or incision on the body part in order to examine it. The ultrasound or sonography does not use any radiations to produce the image of the internal body parts and therefore, ultrasound is considered safe to be performed even for the pregnant mothers to view the developments of the fetus. Ultrasound uses sound waves to form an image of the specific internal body part and therefore, the patient experiences no pain during the ultrasound

Radiology Center at Harding has well-trained professionals who perform the ultrasound. Their GE logic series ultrasound unit is the latest technology, which is used for performing an ultrasound. The GE logic series can produce a detailed and colored image of the ultrasound. Along with this, the technology can carry out Doppler assessment. Radiology Center at Harding keeps them updated with the latest technologies and equipment. Moreover, they attempt to provide the best services to their customers and make their customers feel comfortable and complacent in their calm and friendly environment.How is the ultrasound carried out?Before the ultrasound test, the patient is asked to change his clothes and dress in the gown provided by the hospital. After that, the patient is allowed to lie on the table and a part of the body is exposed to the machine for the test.Then, the sonographer or technician applies a special kind of lubrication or gel on the part under examination. The gel is applied in order to reduce the friction between the skin and the ultrasound transducer as when it is rubbed on the skin. Along with this, the jelly or lubricant helps in transmitting the waves of sound.The transducer transmits sound waves of high frequency. The sound waves travel through the body and get reflected back on hitting any dense part. The computer collects the echoes. The professionals study the image and diagnose the issue.The vast area of ultrasoundGiven below are some medical applications of ultrasound.

Produce an image of the internal parts of the body such as muscles, tendons, joints, internal organs, veins, and arteries. At Radiology center at Harding, one can even get a colored image of the internal structures of the body with the help of GE logic series.

Ultrasound is used to find the cause of any kind of swelling, pain, and infection in the internal parts of the body.

It helps the doctors to perform biopsies, examine the condition of the heart and find the extent of damage of the heart after an attack.

Ultrasound is also used to find the cause of disease

Advantages of Ultrasound

An Ultrasound or also called as a ‘sonograph' by medical professionals is a procedure that utilizes frequency waves that are classified as high-frequency waves to map out what is actually going on inside your body. It uses these said waves to capture images of the organs, tissues or veins inside your body. This is important as doctors do not have to cut you open just to see what is going on and where any problem lies. Other methods like X rays use radiation in order to achieve this purpose, but the ultrasound uses, pretty much, harmless sound waves to get the job done. It is so safe that doctors often perform the sonogram of fetuses (babies still inside the womb). Since there are no cuts performed on your body, it is a completely painless procedure.Doctors now have portable

ultrasound machines as well, so that it can be a mobile procedure during an emergency. This just goes to show how safe the ultrasound is. You do not require a prescription from a doctor to get an ultrasound, if you are a pregnant woman who just wants to see how your baby is doing, you can call us to schedule an appointment and we will set you up at your onvenience.

What is the purpose of an ultrasound scan

What is the first thought that comes to your mind when you think about Ultrasound scans? For most people they always picture a pregnant lady who is eagerly waiting to get a sneak peek of her child that is growing inside her. Fetal imaging is undoubtedly the most common purpose of ultrasound; however, it isn't the only thing that this diagnostic tool can perform. Ultrasound also known as sonography makes the most of sound waves to create ultrasound images which shows doctors what is actually happening inside the human body. With the use of an instrument called transducer, high frequency sounds are emitted which remains inaudible to our human ears. The sound bounces back which is then recorded to determine the shape, size, consistency of the organs and soft tissues.This kind of information is relayed in and it produces real time images on the computer screen. The sonographers or ultrasound technicians at the Radiology center at Harding have special training in this field and do an efficient job while performing the test. The images are then interpreted by a doctor to treat different conditions.What is the purpose of an ultrasound scan?The purpose of an ultrasound isn't limited to pregnancy. It has various uses in the field of pregnancy. From confirming that you are pregnant to diagnosing several conditions - doctors can make the most of ultrasound tests.

Pregnancy

There are a wide range of benefits that ultrasound scans offer during pregnancy. They reveal the due dates, presence of multiple babies or twins, and also helps to rule out the cases of ectopic pregnancies. The use of valuable screening tools helps doctors to every kind of potential problems these includes issues which include birth defects, breech positioning, placental problems, and others. Later in pregnancy, with the help of ultrasound doctors will be able to determine the size of the babies or how large it is going to be at the time of delivery.

For the purpose of diagnostics

If you are a resident of Morristown, New Jersey then you can drop by at Radiology center at Harding to diagnose an array of conditions which are affecting the soft tissues or organs of your body. This includes the blood vessels, heart, gallbladder, liver, pancreas, spleen, bladder, kidneys, thyroid, uterus, eyes, testicles, and ovaries. Though there are certain limitations to the ultrasound as it can't transmit its sound waves through body parts or dense bones.

It is used during different medical procedures

During medical procedures like needle biopsies, doctors can make the most of

Ultrasound imaging. This allows a doctor to remove some tissues from an accurate area inside the body which is then used for testing in labs.Ultrasound scans are also used for the purpose of detecting and treating different soft tissue injuries.The painless, needle or incision free scans serve various purposes. Patients don't have any risk of being exposed life-threatening radiations here. It is a way safer procedure and captures the accurate images of soft tissues.

Some unique facts about ultrasound scan

The basic conception about ultrasound scan according to the majority of people is- It helps in the process of tracking the development of a baby, during the time of pregnancy. But, they are unaware that an ultrasound scan has numerous other things to offer. Now, what is an ultrasound scan? Well, it is a medical test that captures the internal images of the body by using a high-frequency sound wave. Sonography is the other name of ultrasound. Do you know that it has some unique facts to offer? Carry on with your reading to know about those. Some unique facts about ultrasound scan that you may or may not know

There are no risks involved

One of the finest aspects of the ultrasound scan is that it delivers no risk. Instead of using any kind of harmful radiations like x-ray or anything else, it uses high-frequency sound waves to get the inside images of the body. Well, the body absorbs those sound waves in the form of heat, or it gets reflected to the transducer. Maybe, the body will witness a bit rise in the heat, but there will be no adverse effects.

Interesting history of sonogram

The first sonogram witnessed its light in the year of 1794, and it was the brainchild of the obstetrician Ian Donald along with the engineer Tom Brown. But the first clinical use of the sonogram was done in the year of 1950s. Glasgow hospital first used it in the year of 1956. After that, the sonogram has experienced several developments, in the course of time.

Sonogram serves multiple purposes

Earlier, an ultrasound scan was used to detect whether a woman is pregnant or not. But after that, numerous specialists started using it for several purposes like the detection of cyst tumor, uncovering heart problems, determination of the possibility of pregnancy and diagnosis of several gall bladder issues.

Guides a woman to take serious decisions

Pregnant mothers have praised the ability of the ultrasound as it helps in the detection of the fetus health and also reflects the movement of it. As stated by the medics, the majority of women stays unsure about their pregnancy until an

ultrasound scan takes place. It makes sure of the fact that the woman is healthy.

It played a significant role in reducing the rate of abortion

Yes, ultrasound scans helped in the process of reducing the rate of abortion. How? Well, when a woman looks at the ultrasound images of the fetus, they see that that the baby is healthy as well as moving. This affects their psychology, and they step back from their decision of going through an abortion. So, in this way, ultrasound played a significant role in reducing the number of abortions.So, these are some of the unique facts that you should know about the ultrasound scan. And in case, if you need to go through ultrasound, you can head towards

Radiology Center at Harding, which is located at Morristown, New Jersey.

The concept of ultrasound

An ultrasound uses a high-frequency sound wave, which when reflects with the internal organs of the body, delivers an image of that part of the body. The most common usage of ultrasound can be found during the time of pregnancy. The finest part about the ultrasounds is that they are completely harmless to our body as they don’t use any kind of radiations. What they use is high-frequency sound waves, and those waves are not at all harmful to our body. Apart from evaluating fetal developments, ultra-scans are also used to detect problems like liver, kidney, heart or abdomen. The image that they provide is known as a sonogram. Some basic facts about ultrasound scans

Ultrasounds are quite safe to use, and they are widely used as well.

Majority of times, they are used to determine the progress during the time of pregnancy.

Several diagnosis and treatments are also done with the help of ultrasounds.

Before going for an ultrasound scan, you don’t have to go through any kind of special type of preparation.

The concept of ultrasound person, who conducts the process of ultrasound, is known as a sonographer and the images are interpreted by cardiologists, radiologists or any kind of other specialists. While doing an ultrasound scan, the sonographer holds a handheld, wand-like device named transducer, which the sonographer places in the skin of the patient.The sound from the ultrasound travels through the soft fluids and tissues and after that it bounces back after getting reflected on the denser surfaces. In this way, an ultrasound creates images. The term ultrasound refers to the sound, which has a frequency that cannot be heard by the human ears. In case of diagnostic purposes, the frequency range of ultrasound varies from 2 to 28 Megahertz. You must be thinking that higher frequencies of sound will provide you with the better quality of images, but the fact is the higher frequency will be instantly absorbed by the skin as well as other tissues.How an image is captured by an ultrasound scanLet us present with you an example to make you understand the concept of how ultrasound scan generates an image. Well, if you are doing an ultrasound scan of your heart, the sound will flow through the blood present in your heart chamber but if it hits any of the valves; it will just bounce back or echo.Well, the rate of bounce back of the ultrasound depends on the density of the object. The denser the object, the more it will bounce back.Different types of transducers used in the ultrasound scanWell, most of the times, the transducers are placed at the surface of the skin but there are several transducers that are placed internally on the body. Let us know about the different internal transducers:

Endovaginal transducer

Endorectal transducer

Transesophageal transducer

So, this is how ultrasound works, and this is all that you need to know about the ultrasound. And if you want to experience the finest quality of Ultrasound, Radiology Center at Harding is the place for you, which is residing at Morristown, New Jersey.
