过度锻炼伤害心脏

一项新的研究显示,锻炼过猛对心脏会产生伤害. Everyone knows exercise is fundamental for good cardiovascular health, but a new and surprising body of research is finding that too much exercise may also increase the risk of death from heart attack or stroke in patients with existing heart problems. Dr. Nieca Goldberg, a cardiologist and director at NYU Langone Medical Center explains. The new study, which was just published in the journal Heart, tracked a decade's worth of exercise habits and survival of more than 1,000 people with diagnosed -- but stable -- coronary artery disease.
