Ischemic heart disease caused by coronary artery atherosclerosis, or plaque buildup, is the most common cause.

由冠状动脉粥样硬化或血小板积聚引起的缺血性心脏病变是左心衰最常见的病因。

Another large proportion of cases, though, are a result of ischemic heart disease, when the heart cells don't receive enough oxygen and can die off, as with a heart attack.

另一种多见的病因是缺血性心肌病：心脏病发病时，心肌细胞无法获取足够的氧气而坏死。

Of course there are many variations on the basic correlations outlined here depending on the variation in coronary artery anatomy between individuals and the impact of collateral formation in patients with a long history of ischemic heart disease.

当然，根据个体之间冠状动脉解剖结构的变化和长期缺血性心脏病患者侧支形成的影响，这里概述的基本相关性有许多变化。
