ABSTRACT
PURPOSE:
To analyse the influence of unstable coronary syndromes (UCS) in the early and late prognosis after rotational atherectomy (RA).METHODS:
We treated 236 patients with RA between Aug/1992 and May/1996. Patients were divided into two groups A) stable coronary syndromes 120 (51) patients; B) UCS 116 (49) patients. Definitions 1) procedure success (PS)--lesion success in all locations were RA use was attempted, without a major complication; 2) late coronary events (LCE)--angina, MI, additional revascularization or death.RESULTS:
There was a significant predominance of age > 70 (A = 14x B = 24, p = 0.03) in B and previous MI (A = 32x B = 11, p = 0.0001) in A. Other characteristics were similar in both groups, including complex lesions (type B2/C), which were observed in 77A stenosis and 80B lesions. PS was 95in A and 92in B (p = NS). In-hospital major complications were observed in 2.5A and 4.3B patients, (p = NS). One patient died in each group. A and B patients had similar time of follow-up. LCE occurred in 25A and 39B patients (p = 0.002). Recurrence of angina (36x 23; p = 0.01) and target lesion revascularization (29x 18; p = 0.03) were also more frequently required in B cases.CONCLUSION:
This study suggests that UCS (group A) does not implicate in worse acute results after RA. However, UCS patients present greater incidence of late coronary events, particularly recurrence of angina and target-lesion revascularization.Key words
