Editing a gene that prompts a cascade of damage after a heart attack appeared to reverse this inevitable course in mice, leaving their hearts remarkably unharmed, a new study by UT Southwestern scientists showed. The findings, published in Science, could lead to a new strategy for protecting patients from the consequences of heart disease.
On any given Tuesday, you will find Brian C. Jensen, MD, cardiologist and physician-scientist, tending to patients in his cardio-oncology clinic. His schedule is packed to the brim with cancer patients. But not patients with heart cancer. The largest number of patients he sees are cancer patients who have developed, or are at risk of developing, heart damage in response to their chemotherapy regimens.
With numerical simulations, researchers have demonstrated a new way to time weak electrical pulses that can stop certain life-threatening arrhythmias. Publishing their work in Chaos, the group shows that timed pulses are successful in ending atrial and ventricular fibrillations. The study provides early evidence that one theorized approach to controlling fibrillations – adaptive deceleration pacing – can improve the performance of defibrillators.

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.

The researchers proposed the process of focused rotary jet spinning. This team included Qihan Liu, an assistant professor in the University of Pittsburgh Swanson School of Engineering.
Adult survivors of cancer have a higher risk of heart failure and other cardiovascular diseases (CVD) later in life than adults without cancer, according to results of a large study led by Johns Hopkins Medicine researchers.
Researchers from the Georgia Institute of Technology offer a new method to disrupt spiral waves that uses less energy and that may be less painful than traditional defibrillation.
UC San Francisco’s Cardiovascular team is welcoming two highly regarded cardiac surgeons to its renowned program. The specialists will join the newly formed Advanced Heart Failure Comprehensive Care Center (AHF CCC).
Cardiovascular researchers at Virginia Tech’s Fralin Biomedical Research Institute at VTC have published a new study describing how deadly arrhythmias arise from elevated sodium levels, heart tissue irritation and swelling, and sodium channel abnormalities associated with Long QT syndrome. The scientists were the first to examine the impacts of heart tissue swelling and blood chemistry in relation to the syndrome.
Researchers have shown for the first time in mice that heart problems seen in some of the sickest flu patients are caused by direct influenza infection of cardiac cells.
A new study suggests that because of improvements in stent technology and changes in the types of patients receiving stents, the risks of DAPT may now outweigh the benefits for the average patient.
Spotting changes in the heart’s electrical activity may prompt more-aggressive treatment and monitoring.

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.
