[Frequency of angiographic restenosis after 6 months and long-term outcome of coronary angioplasty].
Five hundred patients with a mean age of 59 years were followed up for an average of 32 months after coronary angioplasty. All patients were included in a prospective study comprising coronary angiography at 6 months for 379 patients (91% primary successes). The long-term outcome was evaluated by a questionnaire or telephone interview in all cases. The global primary success rate was 84.4% in this series. The primary failures include 1.8 fatalities, 0.6% myocardial infarction, 2% emergency coronary bypass surgery and 11.2% without immediate clinical consequences. At 6 months, there were 48% of restenoses (182/379 patients) and 28% underwent immediate repeat angioplasty (141/500 patients) with a primary success rate of 91%. After the repeat angioplasty, the restenosis rate was 43% but this varied according to the time from the first restenosis: 60% when the interval was short (under 2 months) compared with 21% when the interval was 6 months (p < 0.01). The actuarial survival rates at 4 years were 95% after successful angioplasty 96% after uncomplicated failures or medically treated restenosis and 98% after bypass surgery. The predictive factors for secondary death were age of over 70 years, previous non-thrombolized myocardial infarction and complications of angioplasty. The long-term outcome was good despite the 48% 6 months restenosis rate requiring revascularisation procedure in 73% of cases.
