[Results of rehabilitation after myocardial infarction in patients more than 60 years of age].
The results of the same rehabilitation protocol are compared in two groups of patients with recent transmural myocardial infarction. The first group consists of 63 males, aged from 40 to 49 (mean 44.5); the second one of 63 males, aged from 60 to 74 (mean 64.7). The age is the only difference between the groups. The training does increase the mean value of the Total Work Performed from 5126 +/- 2201 to 7505 +/- 2455 Kgm (p < 0.001) in the young patients and from 3340 +/- 1414 to 4793 +/- 1598 Kgm (p < 0.001) in the old ones. The amount of increase is 46.4 and 43.5 per cent, respectively. The Heart Rate at fixed level of 75 W decreases from 125 +/- 2 to 119 +/- 1.6 beats per minute (p < 0.001) in the young group and from 119.2 +/- 2.2 to 111.3 +/- 2.2 (p < 0.001) in the old group of patients. The O2 Pulse at 75 W increaes from 8.8 +/- 0.2 to 9.7 +/- 0.25 cc per beat (p < 0.001) in the young subjects and from 9.4 +/- 0.4 to 10.3 +/- 0.4 (p < 0.001) in the old ones. The Double Product at 75 W decreases from 23.6 +/- 0.7 (X 10(3)) to 21.4 +/- 0.5 (p < 0.001) in the young patients and from 24.4 +/- 0.8 to 21.6 +/- 0.7 (p < 0.001) in the old ones. A control performed in 26 subjects of both groups 1 year later, shows a good persistance of the training effect as in young as in old patients. The AA. come to conclusions that: a) The age does not represent a limiting factor for the indication to the rehabilitation after a myocardial infarction; b) the rehabilitation can provide similar results in young and in old patients and the achieved benefits can be similarly maintained; c) the risk of any complication during training is higher in old than in young patients. It compels us to a careful choice of patients and control of the rehabilitation procedure.
