Randomized Controlled Trial Multicenter Study Clinical Trial
Role of aspirin with thrombolytic therapy in acute myocardial infarction.
Thrombolytic therapy has been shown to limit infarct size, improve ventricular function, and decrease mortality in suspected evolving myocardial infarction (MI). Aspirin therapy also decreases mortality as well as stroke and reinfarction in suspected evolving MI. ⋯ The use of aspirin with thrombolysis also protects against the increase in reinfarction observed when thrombolytic therapy is given alone. While ongoing research is evaluating the optimal thrombolytic agent as well as the possible role of heparin, it is already clear that the use of aspirin with thrombolytic therapy will significantly decrease reinfarction, stroke, and vascular mortality in suspected evolving MI.

Multicenter Study Clinical Trial
GISSI trials in acute myocardial infarction. Rationale, design, and results.
The first Gruppo Italiano per lo Studio della Streptochinasi nell'Infarto (GISSI) study showed striking evidence of the effectiveness and safety of intravenous thrombolytic treatment in acute myocardial infarction (MI). Since publication in The Lancet, the original report has become a reference work for every paper which deals with thrombolysis. In addition to GISSI's scientific value, these studies applied formal research to routine clinical practice outside of referral centers. ⋯ The package of treatments recommended after extensive discussion with all the investigators (beta-blocker, aspirin, nitrates) was widely adopted. Now, only five years after the start of the GISSI-1, the overall mortality of Italian patients with acute MI has decreased from 13.0 percent to about 9 percent, and the number of patients with acute MI arriving in hospital within 1 h of the onset of symptoms has increased 50 percent. It is the wish of the GISSI investigators that this approach to treating acute MI will be regarded and acknowledged as their major contribution to the problem.
