#Heart Health Technology

[drsanjaykumar]

In recent years, advancements in cardiac technology have significantly transformed the treatment landscape for patients with heart rhythm disorders. One of the most notable innovations is the leadless pacemaker, a breakthrough that has redefined how cardiologists manage conditions like bradycardia. Dr. Sanjay Kumar, a prominent cardiologist and Director of Cardiology at Fortis Escorts Hospital in Faridabad, is at the forefront of this evolution in heart care, emphasizing the critical role of leadless pacemakers in improving patient outcomes and overall quality of life.

"A study looking at the bearers of artificial hearts found that a subset of them can regenerate heart muscle tissue—the first time such an observation has ever been made.

It may open the door to new ways to treat and perhaps someday cure heart failure, the deadliest non-communicable disease on Earth. The results were published in the journal Circulation.

A team of physician-scientists at the University of Arizona’s Heart Center in Tucson led a collaboration of international experts to investigate whether heart muscles can regenerate.

According to the Centers for Disease Control and Prevention, heart failure affects nearly 7 million US adults and is responsible for 14% of deaths per year. There is no cure for heart failure, though medications can slow its progression. The only treatment for advanced heart failure, other than a transplant, is a pump replacement through an artificial heart, called a left ventricular assist device, which can help the heart pump blood.

“Skeletal muscle has a significant ability to regenerate after injury. If you’re playing soccer and you tear a muscle, you need to rest it, and it heals,” said Hesham Sadek, director of the University’s Sarver Heart Center.

It was previously thought that when a heart muscle is injured, it could never grow back.

“Irrefutable evidence of heart muscle regeneration has never been shown before in humans,” he said. “This study provided direct evidence.”

The project began with tissue from artificial heart patients provided by colleagues at the University of Utah Health and School of Medicine led by Stavros Drakos, MD, PhD, and a pioneer in left ventricular assist device-mediated recovery.

Teams in Sweden and Germany used their innovative method of carbon dating human heart tissue to track whether these samples contained newly generated cells. The investigators found that patients with artificial hearts regenerated muscle cells at more than six times the rate of healthy hearts.

“This is the strongest evidence we have, so far, that human heart muscle cells can actually regenerate, which really is exciting, because it solidifies the notion that there is an intrinsic capacity of the human heart to regenerate,” Sadek said.

“It also strongly supports the hypothesis that the inability of the heart muscle to ‘rest’ is a major driver of the heart’s lost ability to regenerate shortly after birth. It may be possible to target the molecular pathways involved in cell division to enhance the heart’s ability to regenerate.”

In 2011, Sadek published a paper in Science showing that while heart muscle cells actively divide in utero, they stop dividing shortly after birth to devote their energy to pumping blood through the body nonstop, with no time for breaks.

In 2014, he published evidence of cell division in patients with artificial hearts, hinting that their heart muscle cells might have been regenerating because they were able to rest.

These findings, combined with other research teams’ observations that some artificial heart patients could have their devices removed after experiencing a reversal of symptoms, led him to wonder if the artificial heart provides cardiac muscles the equivalent of bed rest like a person needs when recovering from injury.

“The pump pushes blood into the aorta, bypassing the heart,” he said. “The heart is essentially resting.”

Sadek’s previous studies indicated that this rest might be beneficial for the heart muscle cells, but he needed to design an experiment to determine whether patients with artificial hearts were actually regenerating muscles.

Next, Sadek wants to figure out why only about 25% of patients are “responders” to artificial hearts, meaning that their cardiac muscle regenerates.

“It’s not clear why some patients respond and some don’t, but it’s very clear that the ones who respond have the ability to regenerate heart muscle,” he said. “The exciting part now is to determine how we can make everyone a responder, because if you can, you can essentially cure heart failure.

“The beauty of this is that a mechanical heart is not a therapy we hope to deliver to our patients in the future—these devices are tried and true, and we’ve been using them for years.”"

New method enables fast, accurate estimates of cardiovascular state to inform blood pressure management

New Post has been published on https://thedigitalinsider.com/new-method-enables-fast-accurate-estimates-of-cardiovascular-state-to-inform-blood-pressure-management/

New method enables fast, accurate estimates of cardiovascular state to inform blood pressure management

If patients receiving intensive care or undergoing major surgery develop excessively high or low blood pressures, they could suffer severe organ dysfunction. It’s not enough for their care team to know that pressure is abnormal. To choose the correct drug to treat the problem, doctors must know why blood pressure has changed. A new MIT study presents the mathematical framework needed to derive that crucial information accurately and in real time.

The mathematical approach, described in a recent open-access study in IEEE Transactions on Biomedical Engineering, produces proportional estimates of the two critical factors underlying blood pressure changes: the heart’s rate of blood output (cardiac output) and the arterial system’s resistance to that blood flow (systemic vascular resistance). By applying the new method to previously collected data from animal models, the researchers show that their estimates, derived from minimally invasive measures of peripheral arterial blood pressure, accurately matched estimates using additional information from an invasive flow probe placed on the aorta. Moreover, the estimates accurately tracked the changes induced in the animals by the various drugs physicians use to correct aberrant blood pressure.

“Estimates of resistance and cardiac output from our approach provide information that can readily be used to guide hemodynamic management decisions in real time,” the study authors wrote.

With further testing leading to regulatory approval, the authors say, the method would be applicable during heart surgeries, liver transplants, intensive care unit treatment, and many other procedures affecting cardiovascular function or blood volume.

“Any patient who is having cardiac surgery could need this,” says study senior author Emery N. Brown, the Edward Hood Taplin Professor of Medical Engineering and Computational Neuroscience in The Picower Institute for Learning and Memory, the Institute for Medical Engineering and Science, and the Department of Brain and Cognitive Sciences at MIT. Brown is also an anesthesiologist at Massachusetts General Hospital and a professor of anesthesiology at Harvard Medical School. “So might any patient undergoing a more normal surgery but who might have a compromised cardiovascular system, such as ischemic heart disease. You can’t have the blood pressure being all over the place.”

The study’s lead author is electrical engineering and computer science (EECS) graduate student Taylor Baum, who is co-supervised by Brown and Munther Dahleh, the William A. Coolidge Professor in EECS.

Algorithmic advance

The idea that cardiac output and systemic resistance are the two key components of blood pressure comes from the two-element Windkessel model. The new study is not the first to use the model to estimate these components from blood pressure measurements, but previous attempts ran into a trade-off between quick estimate updates and the accuracy of estimates; methods would either provide more erroneous estimates at every beat or more reliable estimates that are updated at minute time scales. Led by Baum, the MIT team overcame the trade-off with a new approach of applying statistical and signal processing techniques such as “state-space” modeling.

“Our estimates, updated at every beat, are not just informed by the current beat; but they incorporate where things were in previous beats as well,” Baum says. “It’s that combination of past history and current observations that produces a more reliable estimate while still at a beat-by-beat time scale.”

Notably, the resulting estimates of cardiac output and systemic resistance are “proportional,” meaning that they are each inextricably linked in the math with another co-factor, rather than estimated on their own. But application of the new method to data collected in an older study from six animals showed that the proportional estimates from recordings using minimally invasive catheters provide comparable information for cardiovascular system management.

One key finding was that the proportional estimates made based on arterial blood pressure readings from catheters inserted in various locations away from the heart (e.g., the leg or the arm) mirrored estimates derived from more invasive catheters placed within the aorta. The significance of the finding is that a system using the new estimation method could in some cases rely on a minimally invasive catheter in various peripheral arteries, thereby avoiding the need for a riskier placement of a central artery catheter or a pulmonary artery catheter directly in the heart, the clinical gold standard for cardiovascular state estimation.

Another key finding was that when the animals received each of five drugs that doctors use to regulate either systemic vascular resistance or cardiac output, the proportional estimates tracked the resulting changes properly. The finding therefore suggests that the proportional estimates of each factor are accurately reflecting their physiological changes.

Toward the clinic

With these encouraging results, Baum and Brown say, the current method can be readily implemented in clinical settings to inform perioperative care teams about underlying causes of critical blood pressure changes. They are actively pursuing regulatory approval of use of this method in a clinical device.

Additionally, the researchers are pursuing more animal studies to validate an advanced blood pressure management approach that uses this method. They have developed a closed-loop system, informed by this estimation framework, to precisely regulate blood pressure in an animal model. Upon completion of the animal studies, they will apply for regulatory clearance to test the system in humans.

In addition to Baum, Dahleh and Brown, the paper’s other authors are Elie Adam, Christian Guay, Gabriel Schamberg, Mohammadreza Kazemi, and Thomas Heldt.

The National Science Foundation, the National Institutes of Health, a Mathworks Fellowship, The Picower Institute for Learning and Memory, and The JPB Foundation supported the study.

Occlusion myocardial infarction (OMI) impacts a large number of people, yet fewer get diagnosed. This is because their ECG fails to show an elevation in the ST region. An elevated ST region indicates the presence of OMI. Such patients can receive great help from immediate reperfusion therapy, but the problem is that no tool can accurately identify them in the initial assessment. At the University of Pittsburgh, USA, scientists conducted a study with a sample space of 7,313 patients in the US with the aim of developing machine-learning models for detecting OMI effectively through ECG. The developed models showed higher accuracy, precision, and sensitivity, outperforming clinicians and commercial interpretation systems. The features of the models were validated by clinical experts as well, increasing the scope for a better understanding of the underlying mechanisms of OMI.

Effective ECG diagnosis of acute coronary syndrome (ACS) in individuals with acute chest pain has long been difficult. Blockages in the coronary arteries cause ACS, a condition where there is less blood flow to the heart. To segregate individuals with ST-elevation myocardial infarction (STEMI) from those with other kinds of ACS, clinicians analyze ST-segment elevation (STE). In the absence of STE on the ECG, a biomarker-driven approach is followed. 

The biomarker-driven approach involves the measurement of cardiac biomarkers such as troponin. But this approach has two significant limitations. First, 25 to 35 percent of individuals with non-STEMI experience occlusion myocardial infarction (OMI), which entails total coronary artery blockage. Such patients are more vulnerable than patients with ACS with an open artery and require urgent insertion of a catheter into the blood vessels of their heart. They are also subjected to unnecessary treatment delays, which obviously increase their mortality risk. Even though ECG findings capable of indicating OMI are described in the literature, they are subtle and include complex changes in the ECG waveform. Thus, visual interpretation by clinical experts proves to be a rather suboptimal approach.

How Telemedicine Enhances Emergency Cardiac Care

Telemedicine is revolutionizing solutions in healthcare and medical science. It is healthcare delivery especially helpful in emergency conditions. With the emergence of advanced healthcare services integration of telemedicine has become a true blessing for humankind. Also, telemedicine solutions play a crucial role in emergency cardiac care. 

In this blog, we are going to explore how telemedicine can enhance emergency cardiac care and make emergency cardiac treatment more accessible and effective. 

What is telemedicine? 

Telemedicine plays a crucial role in emergency care, including cardiac emergencies. However, before we talk about the impact of telemedicine for cardiac care, let's learn briefly about what is telemedicine at first briefly. Telemedicine is also known as telehealth, which uses electronic information and communication technologies to provide healthcare services and support remotely. Telemedicine also enhances both the efficiency and accuracy of emergency healthcare services.

Telemedicine in Emergency Cardiac Care 

Telemedicine solutions help in more than one way to enhance emergency cardiac condition support. Here, we will discuss some essential ways telemedicine helps to enhance emergency cardiac care-

Enhanced triage and consultation 

The first and foremost essential way telemedicine helps to enhance emergency cardiac care is by enhancing triage and consultation. Tele-triage helps healthcare providers to assess the condition of the patient and its severity remotely from a distance. This ensures that cardiac patients get accurate care and support, especially during emergencies. Such telehealth technologies also enable instant consultation from emergency physicians and cardiac specialists.

Enhanced access to emergency care

Another essential way telemedicine helps to improve emergency cardiac care is by enhancing access to emergency care. A cardiac emergency is a critical state that requires immediate access to emergency cardiac care to save a patient's life. And these telehealth solutions work excellently in providing emergency care in cardiac emergencies. Nowadays, cardiac patients can access emergency cardiac care services by leveraging these telehealth solutions, which makes emergency cardiac care more accessible during emergencies. 

Improved decision-making

Decision-making is an essential part of emergency cardiac care. Delays in decision-making can cause significant hazards and even claim life. However, with telemedicine, the decision-making process gets immense improvement as it offers real-time consultation with cardiac specialists. With the help of such telehealth solutions, emergency cardiac care specialists collaborate together remotely with other cardiac experts for better diagnosis and interventions. This further helps in improved decision-making during cardiac emergencies.

Convenience

A cardiac emergency is a special condition which needs immediate care and support. In such conditions, taking the patient to the doctor or taking the doctor to the patient both are time-consuming. However, when patients leverage telehealth solutions they can access emergency cardiac care on time, remotely, according to their convince. 

Quality care

Enhanced emergency cardiac care also means quality care at the right time. When patients and cardiac specialists leverage telemedicine solutions they can access/provide real-time quality care for cardiac emergencies. With telehealth solutions, cardiac specialists diagnose and offer treatment instructions in real time using communication technologies. Therefore, they can provide quality care during cardiac emergencies remotely. 

Streamlined follow-ups

Lastly, telehealth solutions extend beyond emergency care and also include follow-ups and consultations remotely. As a result, these telehealth solutions not only enhance emergency cardiac care but also offer essential aftercare to ensure quality support remotely for post-cardiac emergency care. 

Conclusion 

Cardiac emergencies can be life-threatening and require immediate end effective treatment support to help the patient survive the condition. Advanced healthcare solutions such as telemedicine work miracles in transforming cardiac emergency care. By integrating telemedicine for cardiac care specialists, can provide enhanced cardiac support for emergencies without the need for physical consultation, diagnosis and emergency care.

Detachable cardiac pacing lead may improve safety for cardiac patients

New Post has been published on https://thedigitalinsider.com/detachable-cardiac-pacing-lead-may-improve-safety-for-cardiac-patients/

Detachable cardiac pacing lead may improve safety for cardiac patients

In 2012, Neil Armstrong, the first man to walk on the moon, died of post-surgery complications at the age of 82 following what should have been a routine heart surgery. Armstrong had undergone bypass surgery, the most common open-heart operation in the United States, and a surgery where the overall chance of death has dropped to almost zero.

Armstrong’s death was caused by heart damage that occurred during the removal of temporary cardiac pacing leads. Pacing leads are routinely used to monitor patients and protect against the risk of postoperative arrhythmias, including complete blockages, during the recovery period after cardiac surgery. However, because current methods rely on surgical suturing or direct insertion of electrodes to the heart tissue, trauma can occur during implantation and removal, increasing the potential for damage, bleeding, and device failure.

A coffee chat in 2019 about Armstrong’s untimely death helped inspire new research, published in the journal Science Translational Medicine. The research demonstrates findings that may offer a promising new platform for adhesive bioelectronic devices for cardiac monitoring, diagnosis, and treatment, and offer inspiration for the future development of bioadhesive electronics.

“While discussing the story, our team had a eureka moment that we probably could do something to prevent such complications by realizing a completely atraumatic version of it based on our bioadhesive technologies,” says Hyunwoo Yuk SM ’16, PhD ’21, a former MIT research scientist who is now the chief technology officer at SanaHeal. “It was such an exciting idea, and the rest was just making it happen.”

The team, comprising researchers affiliated with the lab of Xuanhe Zhao, professor of mechanical engineering and of civil and environmental engineering, has introduced a 3D-printable bioadhesive pacing lead that can directly interface with cardiac tissue, supporting minimally invasive adhesive implantation and providing a detachment solution that allows for gentle removal. Yuk and Zhao are the corresponding authors of the study; former MIT researcher Jue Deng is the paper’s first author.

“This work introduces the first on-demand detachable bioadhesive version of temporary cardiac pacing lead that offers atraumatic application and removal of the device with enhanced safety while offering improved bioelectronic performance,” says Zhao.

The development of the bioadhesive pacing lead is a combination of technologies that the team has developed over the last several years in the field of bioadhesive, bioelectronics, and 3D printing. SanaHeal, a company born from the team’s ongoing work, is commercializing bioadhesive technologies for various clinical applications.

“We hope that our ongoing effort on commercialization of our bioadhesive technology might help faster clinical translation of our bioadhesive pacing lead as well,” says Yuk.
