Patients with acute myocardial infarction are frequently not fed hot and cold liquids because of possible deleterious effects on heart rate, blood pressure, and cardiac rhythm. In an attempt to identify and quantify such changes, hot liquid with a temperature in excess of 70 degrees C and cold liquid at an average temperature of 7 degree C were ingested by 20 patients within 36 hours of documented myocardial infarction and by 11 control patients with severe anginal episodes or chest wall syndromes. Heart rate and rhythm were continuously monitored during ingestion of the hot and cold liquids, and blood pressure was recorded intermittently. No patient in either group had a change in cardiac rhythm or an increase in ectopy during ingestion of the hot and cold liquids. Changes in blood pressure and heart rate were also not significant during liquid ingestion by patients with infarction and control patients. The practice of avoiding ingestion of hot and cold liquids by patients with acute myocardial infarction is not supported by these observations.
急性心肌梗死患者常不被给予冷热饮品，因为这可能对心率、血压及心律产生有害影响。为了识别并量化此类变化，20例确诊心肌梗死后36小时内的患者以及11例患有严重心绞痛发作或胸壁综合征的对照患者摄入了温度超过70摄氏度的热饮和平均温度为7摄氏度的冷饮。在摄入冷热饮品期间持续监测心率和心律，并间歇性记录血压。两组中均没有患者在摄入冷热饮品期间出现心律变化或异位心律增加。梗死患者和对照患者在摄入饮品期间血压和心率的变化也不显著。这些观察结果不支持急性心肌梗死患者避免摄入冷热饮品的做法。
