Initial Invasive or Conservative Strategy for Stable Coronary Disease

N Engl J MedPublished

  • Randomised controlled trial

Authors' conclusion

Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used.
