Answer

Older clinical trials, such as TIMI III-B, the VANQWISH (Veterans Affairs Non–Q-Wave Infarction Strategies in-Hospital) study, and the MATE (Medicine versus Angiography in Thrombolytic Exclusion) trial, did not find routine catheterization to be superior to reserving catheterization for patients with recurrent ischemic symptoms or a significantly positive stress test result. Heightened abrupt vessel closure, stent thrombosis, and MI rates were early hazards observed with angioplasty performed in the acute setting of myocardial ischemia. [74, 75]
