110 male subjects, under 60, admitted for myocardial infarction in 1980 and 1981, have been considered. 85 answers to the questionnaire, sent by post have been obtained, 6 pertaining to patients who died in the meanwhile. Among the 79 living patients who replied, 57 (72.1%) had resumed work within the average time of 4.8 months (min. 0.5-max. 12). Return to work has been significantly higher among self-employed people than employees; only 15 subjects had changed job or task. The subjective rating of the actual health status, two years after the infarction, has been satisfactory in 90.5% of cases, in spite of 56.5% complaining of heartburn, 38.1% of dyspnea and 35.7% of palpitation. The work-load has been rated as tiring only by 12.6% of them, while 65.6% have maintained unchanged their work capacity. Electrocardiographic monitoring (by the Holter method), during a normal workday, showed no significant differences between working and retired subjects and, also, in work and normal activity periods. 19 subjects (47.5%) presented ventricular arrhythmias, in 12 cases at high risk, most of them being unaware of it. These arrhythmias were more frequent during wake periods, but not strictly connected to the type and the quality of the work activity. The patients subjected to rehabilitation showed no differences in the cardiovascular patterns during the ergometric test and ECG monitoring when compared to those not subjected to rehabilitation.
对1980年和1981年收治的110名60岁以下因心肌梗死入院的男性患者进行了研究。通过邮寄问卷共获得85份回复，其中6份来自在此期间死亡的患者。在79名回复问卷的在世患者中，57名（72.1%）在平均4.8个月（最短0.5个月 - 最长12个月）内恢复了工作。个体经营者的复工率显著高于雇员；只有15名患者更换了工作或任务。心肌梗死后两年，90.5%的患者对实际健康状况的主观评价令人满意，尽管有56.5%的患者抱怨烧心，38.1%的患者抱怨呼吸困难，35.7%的患者抱怨心悸。只有12.6%的患者认为工作负荷很累，而65.6%的患者工作能力保持不变。在正常工作日通过动态心电图监测（采用Holter方法）显示，在职和退休患者之间以及工作和正常活动期间均无显著差异。19名患者（47.5%）出现室性心律失常，其中12例为高危患者，大多数患者对此并不知晓。这些心律失常在清醒期间更为频繁，但与工作活动的类型和质量并无严格关联。与未接受康复治疗的患者相比，接受康复治疗的患者在运动试验和心电图监测期间的心血管模式并无差异。
