The rate of heart attacks, strokes, and other cardiovascular complications increased among patients hospitalized with COVID-19 between March 2020 and December 2021, according to a new study led by UT Southwestern Medical Center researchers. The rise came even as patients hospitalized with the virus tended to be younger and less likely to have had cardiovascular disease (CVD) as the pandemic wore on.

The study tracked 26,539 people from 33 countries in Asia, Europe, Australia North and South America with both CAD and PAD. Of the patients tracked, 24,119 had CAD and 7,163 had PAD, with some having both. Participants’ average age was 68 years old and 78 per cent were men. Over the 30 months that participants were monitored, a total of 1,391 adverse events occurred, of which 1,262 were CVD-related and 140 were PAD-related, with some people having both. Researchers found the incidence of CVD and PAD events was highest in patients with a poor diet, measured by the Alternate Healthy Eating Index (AHEI) metric, with zero being the worst diet score and 70 being the best.

A new study by researchers at Washington University School of Medicine in St. Louis reveals that a connection between the body and mind is built into the structure of the brain. The study shows that parts of the brain area that controls movement are plugged into networks involved in thinking and planning, and in control of involuntary bodily functions such as blood pressure and heart rate.

A new CALM mutation causes lethal arrhythmia in humans. Using cardiomyocytes -- or heart muscle cells -- from human iPS cell and recombinant calmodulin proteins, the group studied catecholaminergic polymorphic ventricular tachycardia -- or CPVT, a rare and life-threatening genetic condition. The team was able to reproduce severe arrhythmia in patient-derived iPS cell models of exercise-induced CPVT with calmodulin mutations.

According to some estimates, up to 80% of patients who experience a ruptured abdominal aortic aneurysm will die before they reach the hospital or during surgery. But early intervention can prevent rupture and improve outcomes. In Physics of Fluids, researchers make a computational model of the cardiovascular system in order to predict early AAA rupture and monitor patients’ blood vessel conditions. They mimicked specific health conditions and investigated various hemodynamic parameters using image-based computational blood dynamics.

A heartbeat is a carefully coordinated series of electrical signals led by sodium ion channels, which tell the heart when to contract and to relax. Any disruption to these signals may lead to cardiac diseases such as an irregular heartbeat, or arrhythmia. Two researchers at Washington University in St. Louis have taken a closer look at this process at the molecular level and have found what may provide new insights into different heart conditions and how to develop better therapies.
