Meta-analysis supports elective revascularization and medical therapy for reducing cardiac death

The ISCHEMIA trial found no significant difference between an invasive vs. a conservative strategy in patients with chronic coronary syndromes and moderate to severe ischemia at a mean of 3.2 years. However, the cumulative difference in the estimates of cardiac death between the invasive and conservative strategies tended to increase numerically over time (e.g., 0.3% in favor of the invasive strategy at two years and 1.3% at five years). Because the ISCHEMIA trial was not powered for cardiac mortality and did not focus on long-term follow-up, the rationale for a meta-analysis emerged.
