老年急性心肌梗塞晚发心原性猝死的临床及病理分析

为了分析老年急性心肌梗塞（ＡＭＩ）２周后发生心原性猝死的原因，本文总结了１２例心原性猝死患者，其中６例进行了尸检。认为无论是持续心肌电不稳定所致的原发性室颤，还是梗塞早期的全并症，如休克、心功能不全，梗塞后心绞痛引起的继发性室颤均为晚发心原性猝死的常见原因。尸检结果表明，老年ＡＭＩ晚发心原性猝死多发生于冠脉病变严重者。对于室颤高危患者应采取积极预防措施，如抗心律失常药物的合理应用、改善冠脉循环及改

Clinical and pathologic analysis of late sudden cardiac death in acute myocardial infarct of the elderly

In order to analysis the cause of sudden death in elderly acute myocardial infarction (AMI) patients, we studied 12 elderly patients with sudden cardiac death, among whom 6 were autopsied. The necropsy results showed that late sudden cardiac death mostly occurred in cases with serious coronary diseases. Thus in these patients, prophylactic treatment shold be instituted, such as antiarrhythmic drugs, drugs improving coronary circulation and cardiac function as well as the amelioration of the inducintg factors in order to decrease the incedence of sudden death.
