The patient’s physical examination is unremarkable. Which of the following is the lead- ing cause of death among people age 65 years or older?

一位70岁的老人走进医生的办公室做例行检查。他的既往病史很明显是心脏病发作，为此他每天服用阿司匹林和β受体阻滞剂。他养成了安全的习惯，开车时总是系着安全带。在过去的几年里，他的健康状况一直“很好”，尽管他很担心他的妻子，因为她最近患了轻度中风。他否认有任何视力丧失或运动或感觉障碍。患者的体格检查无异常。下列哪项是65岁或65岁以上人群的主要死亡原因?

(A) Heart disease心脏病

(B) Malignancy恶性肿瘤

(C) Motor vehicle crashes 机动车碰撞

(D) Stroke中风

(E) Suicide自杀

答案解析：

心脏病是老年人(65岁及以上)的主要死亡原因，如果把所有年龄相加，也是主要死亡原因。由于患者既往有心肌梗死史，因此他发生后续心脏事件的风险特别高。心脏事件的其他主要危险因素包括高血压、高胆固醇血症和糖尿病。

正确答案：A
