心源性猝死仍然是美国的主要死因,每年导致超过35万人死亡,受害者的存活率仍然很低。大多数幸存者面临复发的重大风险。典型的基质是慢性--伴有纤维化的异常心肌(通常来自先前的心肌梗死)和左心室功能障碍。心源性猝死的急性触发因素主要是电、缺血、代谢、神经激素和药理学。在大多数心电图记录的心源性猝死病例中,药物-底物相互作用似乎导致室性心动过速和室颤。初步复苏后,幸存者需要进行全面的心血管评估,包括冠状动脉解剖结构、左心室功能和室壁运动异常的定义,以及电生理评估。必须尝试确定每个幸存者的可纠正触发器是什么。管理应解决所有可逆的触发因素,如急性缺血和电解质异常,并应包括修改或纠正促炎底物。经验性抗肿瘤治疗在这种改变中没有优势。抗心律失常药物的药物治疗应遵循客观的治疗终点,最好通过使用程控心室刺激和系列电生理学研究来实现。其他治疗方法包括手术抑制室性心动过速和植入心律转复除颤器。
Sudden cardiac death remains a leading cause of death in the United States, accounting for more than 350,000 deaths each year, and the survival rate of victims remains low. Most survivors face a significant risk for recurrence. The typical substrate is chronic--abnormal myocardium with fibrosis (often from previous myocardial infarction) and left ventricular dysfunction. Acute triggers for sudden cardiac death are primarily electrical, ischemic, metabolic, neurohormonal, and pharmacologic. In most electrocardiographically documented cases of sudden cardiac death, the trigger-substrate interaction appears to result in ventricular tachycardia and fibrillation. After initial resuscitation, survivors need a thorough cardiovascular evaluation, including definition of coronary anatomy, left ventricular function, and wall-motion abnormalities, as well as an electrophysiologic evaluation. An attempt must be made to determine what each survivor's correctable triggers are. Management should address all reversible triggers, such as acute ischemia and electrolyte abnormalities, and should include modifying or correcting the arrhythmogenic substrate. Empiric antiarrhythmic therapy offers no advantage in such modification. Pharmacologic therapy with antiarrhythmic drugs should be guided by an objective therapeutic endpoint, which is best accomplished through the use of programmed ventricular stimulation and serial electrophysiologic studies. Other therapeutic options include surgical suppression of ventricular tachycardia and implantation of a cardioverter defibrillator.
