Ejection fraction (EF) measures the amount of blood pumped out of your heart's lower chambers, or ventricles. It's the percentage of blood that leaves your ventricle when your heart contracts. The ...

A PHASE 1 trial has found that single-fraction preoperative ablative stereotactic partial breast irradiation (sPBI) is safe and yields high pathological complete response rates in selected patients ...

The angiotensin receptor–neprilysin inhibitor sacubitril–valsartan led to a reduced risk of hospitalization for heart failure or death from cardiovascular causes among patients with heart failure and ...

Scientists have directly measured the minuscule electron sharing that makes precious-metal catalysts so effective. Their new technique, IET, reveals how molecules bind and react on metal surfaces with ...

Sodium–glucose cotransporter 2 inhibitors reduce the risk of hospitalization for heart failure in patients with heart failure and a reduced ejection fraction, but their effects in patients with heart ...
