Why the study?

Do left ventricular function, coronary anatomy, or electrophysiologic characteristics differentiate patients with aborted sudden death from those with sustained VT after myocardial infarction?

Population

42 patients referred for evaluation of sustained ventricular tachycardia or surviving 'aborted' sudden death…

Implication

May aid post-MI sudden death risk stratification; leaves open prospective validation before guiding therapy.

Structured PICO

Do left ventricular function, coronary anatomy, or electrophysiologic characteristics differentiate patients with aborted sudden death from those with sustained VT after myocardial infarction?

P
Population
42 patients referred for evaluation of sustained ventricular tachycardia (VT) or surviving 'aborted' sudden death for more than 9 days after myocardial infarction.
I
Intervention
Patients surviving 'aborted' sudden death
C
Comparator
Patients with sustained ventricular tachycardia (VT) without sudden death
O
Outcome
Differences in left ventricular function, coronary anatomy, and electrophysiologic characteristics (assessed via cardiac angiography and programmed electrical stimulation)surrogate

Patients with aborted sudden death after myocardial infarction exhibit distinct electrophysiologic characteristics, including shorter VT cycle lengths and more frequent polymorphic VT/VF, compared to those with sustained VT.
