The cardiac pacemaker of the future could be powered by the heart itself, according to researchers in China. Current cardiac pacemakers use a battery power supply and leads to keep hearts beating regularly. Yi Zhiran and his group are investing batteryless powering and leadless pacing, harvesting kinetic energy from the heart to power the lifesaving device. The energy is harvested by the buckling of the encapsulated structure of the pacemaker, creating buckled piezoelectric energy.
Receiving the diagnosis of a genetic heart disease such as long QT syndrome, which can cause sudden cardiac death, has long been a game-ender for young athletes. But a 20-year study at Mayo Clinic following such athletes who were allowed to return to play suggests that the risks can be managed through a shared decision-making process. The retrospective study findings will be presented at the annual meeting of the Heart Rhythm Society on Tuesday, July 27, and simultaneously published in the Journal of the American College of Cardiology.
Northwestern Medicine Bluhm Cardiovascular Institute recently became the first cardiovascular program in the United States to use the new VeriSight Pro ICE catheter during a cryoablation procedure to treat a heart arrhythmia.

In Biophysics Reviews, researchers provide an update on how electrical impulses in the heart travel from cell to cell. The connections between cells forming the low resistance pathway and facilitating the current flow are called gap junctions. Each consists of many channels, which are formed when specific proteins from one cell dock and fuse to the proteins from another cell. The scientists delve into the properties of gap junctions and their constituent proteins.

A new research paper funded in part by the National Heart, Lung and Blood Institute (NHLBI) shows a clear advantage of genetic testing in helping health care providers choose the appropriate anti-platelet drug. Testing helps determine if a patient carries genetic variants in CYP2C19 that cause loss of its function. These variants interfere with the body’s ability to metabolize and activate clopidogrel, an anti-platelet medication.

The heart cannot regenerate new tissue, because cardiomyocytes, or heart muscle cells, do not divide after birth. However, researchers have now developed a shape memory polymer to grow cardiomyocytes. Raising the material’s temperature turned the polymer’s flat surface into nanowrinkles, which promoted cardiomyocyte alignment. The research is part of the growing field of mechanobiology, which investigates how physical forces between cells and changes in their mechanical properties contribute to development, cell differentiation, physiology, and disease.

ROCHESTER, Minn. ― Heart patients who undergo percutaneous coronary intervention (PCI) or stent placement― nonsurgical procedures to improve blood flow to the heart ― are typically prescribed anti-platelet therapy to avoid blood clots that can lead to a heart attack or stroke. New research from the international TAILOR-PCI trial, the largest pharmacogenetics clinical trial in cardiology, suggests that genetic testing could potentially be a useful tool to help select antiplatelet medication. Pharmacogenetics is the use of a patient’s genetic makeup in prescribing treatments that are likely to be most successful.

It also incorporates the latest findings from UM cardiology researchers studying how the coronavirus can affect the heart and its surrounding tissues.
MacNeal Hospital is the first hospital in Illinois to participate in a national, randomized clinical trial using daily vital signs and lung pressure measurement to manage patients with congestive heart failure (CHF). The PROACTIVE-HF trial utilizes a new monitoring system, coupled with a pressure sensor, implanted directly into a blood vessel in the lung. This system provides information that is recorded and transmitted over a cellular or Wi-Fi connection to a patient’s provider, allowing for medication changes, if necessary, to prevent further health deterioration or hospitalization.
A newly published study of flies found that protecting liver function also preserves heart health. The research could lead to new therapeutic approaches in human health and illuminate the role of understudied organelles known as peroxisomes.
Many hospitals across the country have noticed an increase of people ignoring life-threatening symptoms. They are choosing to stay home, instead of seeking care at an emergency department. When they do arrive at the hospital, the patient has lost critical time to receive life-saving treatments.

A Polygenic Risk Score — a genetic assessment that doctors have hoped could predict coronary heart disease (CHD) in patients — has been found not to be a useful predictive biomarker for disease risk, according to a Vanderbilt study published in the Journal of the American Medical Association.
An approach based on artificial intelligence (AI) may allow EKGs to be used to screen for hypertrophic cardiomyopathy in the future. With hypertrophic cardiomyopathy, the heart walls become thick and may interfere with the heart’s ability to function properly. The disease also predisposes some patients to potentially fatal abnormal rhythms. Current EKG technology has limited diagnostic yield for this disease.
The most common type of heart disease ― coronary artery disease ― affects 6.7% of adults and accounts for 20% of 2 in 10 deaths of adults under age 65. The condition builds over time as inflammation and cholesterol-containing plaques settle in the heart’s arteries, where they can eventually cause narrowing and blockages that lead to a heart attack.
