人们相信糖尿病人死于心脏病过高的死亡率是由于冠状动脉粥样硬化,但冠心病的许多危险因素对糖尿病人与非糖尿病者来说均常见。实际上,糖尿病人的心脏病与冠心病非同义。有证据表明糖尿病人的心脏病包括冠状动脉粥样硬化、心肌病变、微血管病变及植物神经病变的可变的结合。据国外某些报告,几乎50％的糖尿病人死于心脏病。死亡率的增加归咎于冠状动脉粥样硬化,此病在糖尿病中远比一般人群中常见。据估计心肌梗塞的危险为非糖尿病者的2.5倍。糖尿病人心脏易损性增加的原因尚不明确。
It is believed that death from diabetes is due to coronary atherosclerosis, but many of the risk factors for coronary heart disease are common in both diabetics and non-diabetics. In fact, heart disease in diabetics is not synonymous with coronary heart disease. There is evidence that diabetics have a variable combination of heart disease including coronary atherosclerosis, cardiomyopathy, microangiopathy and autonomic neuropathy. According to some reports abroad, almost 50% of diabetics die of heart disease. The increase in mortality is attributed to coronary atherosclerosis, which is more common in diabetes than in the general population. It is estimated that the risk of myocardial infarction is 2.5 times more than those without diabetes. The cause of increased heart vulnerability in diabetics is not clear.
