[The clinical outcomes of patients undergoing revascularization for acute coronary syndrome].

OBJECTIVE

To evaluate short-term and long-term prognosis of revascularization in patients with acute coronary syndrome.

METHODS

A total of 6005 patients who received coronary revascularization in our institution between July 2003 and September 2005 were enrolled. The patients were followed up in clinic or by telephone after discharge between September 2006 and November 2006. The clinical and prognosis data of all-cause mortality, neo-myocardial infarction, nonfatal stroke, and re-revascularization of ST-segment elevation myocardial infarction (STEMI), non ST-segment elevation myocardial infarction (NSTEMI) and major adverse cardiovascular and cerebrovascular events (MACCE) were analyzed.

RESULTS

Among 4865 acute coronary syndrome patients, 955 cases were STEMI; 263 cases were NSTEMI; and 3647 cases were unstable angina (UA) pectoris. There were no significant difference for in-hospital mortality and late mortality (18 month survival 96%, 98% and 98%) between patients with STEMI, NSTEMI and UA. Patients with UA had lower MACCE rate (18 month non-MACCE survival of STEMI, NSTEMI and UA group were 86%, 86%, and 89% respectively).

CONCLUSIONS

Despite different clinical characteristics, patients with STEMI, NSTEMI and UA undergoing revascularization had similar short-term and long-term mortality. Patients with UA had lower MACCE rate.
