title: Early intervention with angiotensin-converting enzyme inhibitors during thrombolytic therapy in acute myocardial infarction: rationale and design of captopril and thrombolysis study. CATS investigators group.
abstract: The adjunctive use of angiotensin-converting enzyme (ACE) inhibitors with thrombolytic therapy early during acute myocardial infarction offers theoretic advantages. In the acute phase, captopril may scavenge free radicals, blunt the catecholamine response, elicit coronary vasodilation, and increase prostacyclin and bradykinin levels. In the chronic phase, ventricular remodeling may be attenuated. At present, a large number of controlled clinical trials mainly focusing on the effects of ACE inhibition in the chronic phase are underway. Only a few studies concentrate on the effect of acute intervention with ACE inhibitors in ischemia-reperfusion, i.e., thrombolysis in myocardial infarction. In April 1990 under auspices of the Interuniversity Cardiology Institute of the Netherlands, a large nationwide acute intervention trial with captopril in 280 patients receiving thrombolytic therapy was started, the Captopril and Thrombolysis Study (CATS). The primary hypothesis of CATS supposes a very early effect of ACE inhibition on evolving myocardial damage due to ischemia and the consequences of early reperfusion. This will be evaluated by serial echocardiography, Holter monitoring and neurohumoral measurements immediately on thrombolysis and during the first year after myocardial infarction.
