糖尿病性冠心病临床表现有哪些特点

来源:华人健康网 | 发布时间:2010-09-16 09:02:36 | www.chinesejk.com

  糖尿病患者由于血脂高、血糖高、血液黏度高,极易并发动脉粥样硬化。动脉粥样硬化常首见于冠状动脉,脂质沉着于冠状动脉内膜上,造成管腔狭窄,引起心肌供血不足,使心肌缺血、缺氧,这就是冠心病。糖尿病病人患冠心病比非糖尿病病人高2~3倍,因此,糖尿病是冠心病发生和发展的主要危险因素之一。

  糖尿病患者患冠心病与非糖尿病患者患冠心病的临床表现大致相同,主要表现为心绞痛、心肌梗死、心力衰竭和心律失常。所不同的是发病年龄较轻、病情进展快、病情较严重、病死率较高,尤其是女性较为多发。因为自主神经受损,心肌缺血时疼痛常不明显。所以,无痛性心肌梗死常见、临床上常被忽视,易发生猝死,应尽早就医。

  糖尿病并发心肌梗死时,可因应激状态使血糖明显升高,一般常需胰岛素治疗,待病情稳定后再恢复用口服降糖药治疗。
