急性心肌梗塞PTCA术病人的康复运动方案

Rehabilitation exereise protocol of patients with AMI after PTCA

观察16例急性心肌梗塞 PTCA 术病人的康复运动,根据心梗部位、心功能和冠脉阻塞程度,进行3个阶段康复运动方案。心功能Ⅱ级和Ⅲ级病人,在6.59±2.11 min 内完成400m 步行试验,METs达2.86±0.42,自觉劳累程度(RPE)为13。9例有单支和双支冠脉阻塞的病人,其心脏功能容量为5.4～6.7METs。当运动强度从第1阶段到第3阶段增加时,16例病人的双乘积(心率×收缩血压)降低,RPE无明显变化。经过3个阶段康复运动,改善了心脏功能,提高了心血管效率,为维持冠脉再通,使防止再狭窄成为可能。

The rehabilitation exercise protocol of 16 patients with AMI after PTCA was carriedout. The protocol of 3 stages rehabilitation exercise was designed according to the size of MI,degree of occluded coronary artery and cardiac function class.The cardiac function capacity was measured by using two kinds of exercise testing during the rehabilitation program process.7 patients with cardiac function class Ⅱ and Ⅲ completed 400m walking test in 6.59±2.11min and reached the values of METs at 2.86±0.42 with the rating of perceived exertion(RPE)in 13,the range of cardiac function capacity covered from 5.4～6.7 METs in 9 patients with single and double coronary artery obstruction.As the exercise intensity increased from 1 to 3 stages, the rate-pressure product(Rpp)decreased in 16 patients with no change in RPE.In conclusion,rehabilitation exercise protocol of 3 stages could improve the cardiac function capacity and elevate the vascular efficiency in patients with complicated medical status and reconditioning status,and the protocol provided the possibility in maintaining the reca- nalized coronary artery.
