The incidence of vomiting before the administration of analgesics was studied in 109 patients admitted to hospital as emergencies with prolonged ischaemic cardiac pain. In transmural myocardial infarction (58 patients) the incidence was 43% (anterior infarction 58%, inferior infarction 41%). Of the 23 patients with myocardial necrosis but without transmural infarction (that is, those with diffuse or subendocardial necrosis) and the 28 with coronary insufficiency but no necrosis, only one patient in each group experienced vomiting. When vomiting occurs early in association with cardiac pain transmural infarction may be expected in 90% of patients.
对109例因持续性缺血性心前区疼痛作为急诊入院的患者，研究了镇痛药给药前呕吐的发生率。在透壁性心肌梗死患者（58例）中，发生率为43%（前壁梗死为58%，下壁梗死为41%）。在23例有心肌坏死但无透壁性梗死的患者（即有弥漫性或心内膜下坏死的患者）和28例有冠状动脉供血不足但无坏死的患者中，每组仅1例患者出现呕吐。当呕吐与心前区疼痛早期同时出现时，90%的患者可能发生透壁性梗死。
