The incidence and the prognostic value of exertional hypotension was studied in 488 consecutive patients admitted to the Montescano Rehabilitation Center after acute myocardial infarction. During a symptom-limited bicycle ergometric test performed 28 to 60 days after acute myocardial infarction 33 patients (6.8%) showed exertional hypotension. These patients were grouped according to effort S-T segment modifications: Group A (n = 13) with S-T segment depression in ECG-leads without Q waves; Group B (n = 11) with S-T segment elevation in leads where Q waves were present; Group C (n = 9) with no exercise S-T changes. Group B patients had a larger infarct size by ECG criteria and a lower maximal work capacity at the functional stress test. The follow-up of the patients after discharge was 28.3 +/- 13.2 months. During rehabilitation and follow-up, 2 patients of Group B died and 5 suffered an acute pulmonary oedema; 3 patients of Group A and 1 of Group B had angina at rest. Group C patients had no complications. Thus, exertional hypotension and S-T elevation appear to be predictive of future cardiac event.
对蒙特斯卡诺康复中心收治的488例急性心肌梗死后连续入院的患者进行了运动性低血压的发生率及预后价值研究。在急性心肌梗死后28至60天进行的症状限制性自行车测力计测试中，33例患者（6.8%）出现运动性低血压。这些患者根据运动时ST段改变分组：A组（n = 13），心电图导联ST段压低且无Q波；B组（n = 11），有Q波导联的ST段抬高；C组（n = 9），运动时ST段无变化。根据心电图标准，B组患者梗死面积更大，功能应激测试时最大工作能力更低。患者出院后的随访时间为28.3±13.2个月。在康复和随访期间，B组有2例患者死亡，5例发生急性肺水肿；A组有3例患者、B组有1例患者出现静息性心绞痛。C组患者无并发症。因此，运动性低血压和ST段抬高似乎可预测未来心脏事件。
