Abstract

Fifty-two survivors of prehospital sudden coronary death (SCD) were studied with angiography and cardiac catheterization. Coronary bypass surgery (CAB) was performed and combined with medical therapy in 24 patients and 28 patients were treated with medical therapy alone. Severity of coronary artery disease (CAD), left ventricular function, and clinical characteristics are described in the surgical and medical groups. Most patients had at least two-vessel CAD and left ventricular dysfunction was common. Nineteen of the 24 surgical (79%) and 17 of the 28 medical patients (60%) had a primary dysrhythmia without an associated acute myocardial infarction (MI) as the cause of their SCD. After a maximal follow-up of 80 months (mean 38.2 months in surgical group, 32.2 months in medical group), there have been 12 deaths. Eight of the 10 cardiac deaths occurred in patients showed initial SCD was related to ventricular fibrillation (VF) not associated with acute MI. Four of these 10 deaths were in the surgical group and six were in the medical group. Two surgical patients died in the early postoperative period; the other two died from recurrent VF 36 and 48 months after SCD. No perioperative or postsurgical MIs have occurred and only two ...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
