Big-Hearted: Arrhythmia in the World’s Largest Living Animal

Mariam Malik ‘22 Bradycardia is a slower-than-normal heart rate, and can vary depending on age and physical condition. According to the American Heart Association, a heart rate lower than sixty beats per minute (BPM) qualifies as bradycardia. Tachycardia, on the other hand, is a heartbeat that is too fast, specifically one that beats over a hundred times per minute. Both conditions vary by age and … Continue reading Big-Hearted: Arrhythmia in the World’s Largest Living Animal

Figure 1. Cardiac imaging techniques, such as echocardiograms and cardiac MRI, allow us to view the structure of the heart in order to diagnose and monitor heart disease.

New Model Predicts How Genetics Affects Heart Structure

By Gene Yang ’19 Congenital heart disease is the most common birth defect in the world. This broad group of genetic conditions affect the heart’s structure and function in different ways, with symptoms ranging from harmless to fatal. However, very little is known about how a human’s genetic makeup affects cardiovascular development. A recent study, which constructed a model that predicts correlations between genetics and … Continue reading New Model Predicts How Genetics Affects Heart Structure

Evaluations of the First Dissolvable Cardiovascular Stent

By Jessica Desamero Heart disease in the U.S. is one of the leading causes of death. The most common type is coronary heart disease (CAD), which can lead to heart attacks. It is caused by plaque buildup in arteries that supply the heart with blood, causing them to narrow. To this day, bare-metal stents have been inserted in CAD patients to counter-act this blockage. But … Continue reading Evaluations of the First Dissolvable Cardiovascular Stent
