This pre-specified protocol originally included 777 patients with chronic kidney failure. These patients are a special population of higher risk where we might be able to see the advantage of a more aggressive initial strategy.
Death or MI rate (combined primary end point) resulted 36.4% for the invasive strategy vs. 36.7% for the initially conservative strategy with optimal medical treatment (HR 1.01; CI 95% 0.79-1.29).
Secondary end points such as death rate considered separately, non-fatal MI, hospitalization due to unstable angina, cardiac failure or cardiac arrest also resulted practically identical with 38.5% vs 39.7%, respectively (HR 1.01; CI 95% 0.79 to 1.29).
Stroke rate increased with the invasive strategy (HR 3.76; 95% CI 1.52-9.32) as well as risk of dialysis HR (1.48; CI 95% 1.04-2.11).
