Uncertainty surrounding how truncated titin proteins (TTNtvs) cause dilated cardiomyopathy (DCM) and peripartum cardiomyopathy (PPCM) led to investigations that could better inform therapies for these ...

A muscle patch crafted from stem cells has improved cardiac function in monkeys with heart disease. It is now being tested in a small number of people, with early results from the first recipient ...

The heart functions as a muscle which needs continuous movement for proper operation, according to Dr. London. The heart functions like other muscles because it requires regular use, to stay strong.

Accurately measuring electrical signals and calcium levels in the heart can lead to earlier treatment of potentially fatal conditions, such as heart attack or congestive heart failure. Calcium plays ...

Researchers at the University of Washington, Seattle, have used human embryonic stem cell–derived cardiomyocytes (hESC-CMs) to restore heart function in macaque monkeys with heart failure. The ...

The idea that physical exercise could deplete our cardiac reserve has persisted for decades, but Australian research is now ...

Slower gait speed is independently associated with an increased risk for cardiovascular death or worsening heart failure in patients with stable heart failure with reduced or improved left ventricular ...

Patients with dilated cardiomyopathy have an increased risk of papillary muscle scarring (papSCAR), which was found to be independently associated with cardiac death, heart failure events, and ...

Scientists made a fake fish out of human heart cells that can swim on its own. The experiment is a first step toward making artificial heart muscles work together in a lab. While the fish is a ...

In two large studies of heart attack survivors, beta-blocker drugs benefited those with mildly impaired heart function Contradictory trial results seen in patients without heart dysfunction More data ...
