Low-Cost Disease Diagnosis by Mapping Heart Sounds
In the Journal of Applied Physics, researchers develop a method to identify aortic valve dysfunction using complex network analysis that is accurate, simple to use, and low-cost. They used heart sound data to create a complex network of connected points, which was split into sections, and each part was represented with a node. If the sound in two portions was similar, a line was drawn between them. In a healthy heart, the graph showed two distinct clusters of points, with many nodes unconnected. A heart with aortic stenosis contained many more correlations and edges.

Batteryless Pacemaker Could Use Heart’s Energy for Power
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.
20-year Mayo Clinic study suggests return to play is manageable for athletes with most genetic heart diseases
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.

Electric Signals Between Individual Cardiac Cells Regulate Heartbeat
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.

Genetic testing proves beneficial in prescribing effective blood thinners
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.

Using Stimuli-Responsive Biomaterials to Understand Heart Development, Disease
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.

Largest pharmacogenetic clinical trial in cardiology shows potential benefit in individualized approach to anti-platelet therapy
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.
