问:1989年的时候我做了主动脉瓣置换术,当年我45岁。去年,我又患上了主动脉夹层,当时的外科医生嘱咐我不要做任何心脏运动或抗阻训练,并且尽量稳定心率在较慢的水平。但是,如今我的心脏病专家告诉我可以做一些轻度的心脏运动以及抗阻训练,但是就需要留意血压。两个意见是矛盾的,那么我应该听从谁的呢? 读者唐先生 Q: I did aortic valve replacement in 1989 when I was 45 years old. Last year, I suffered from an aortic dissection. At that time, the surgeon asked me not to do any heart exercise or resistance training and to stabilize my heart rate at a slower rate. But now my cardiologist tells me that I can do some mild heart exercise and resistance training, but I need to pay attention to blood pressure. Two opinions are contradictory, then who should I listen to? Reader Mr. Tang
