Abstract Approximately 10 to 15% of patients surviving acute MI will die within one year, and most of these deaths will be due to occurrence of a malignant ventricular arrhythmia (VT and/or VF). Despite considerable improvement in risk stratification after MI, the identification of patients who are at risk of sudden and/or arrhythmic death remains imprecise. Attempts to identify those patients who will experience sudden death from results of ambulatory ECG monitoring, assessment of left ventricular function, and exercise testing have proved disappointing (Richards et al., 1991). |
