[Influence of sex on the prognosis of high risk acute coronary syndromes treated by early angioplasty].
The aim of this study was to evaluate the influence of sex on the prognosis of high risk acute coronary syndromes treated early with angioplasty. Over a period of two years, 694 consecutive patients (151 female, 543 male) underwent revascularisation within the first 24 hours of an acute coronary syndrome without permanent ST elevation (ST depression (52.5%) or relapse of angina despite medical treatment (47.5%). The females were older than the males (67.9 vs 62.3 years; p < 0.0001), smoked less (7.3 vs. 32.8%; p < 0.001) and had a higher prevalence of hypertension (53 vs. 42.1%; p = 0.017). The angiographic characteristics were equivalent in both sexes, except for a lower frequency of thrombus in the females (6.9 vs. 15.2%; p < 0.0001). All lesions were treated with endoprosthesis implantation. The angiographic success rate was comparable (94 vs. 93.7%) as was the rate of major cardiac events while in hospital (3.8 versus 4%). With an average survival of 2 years, the incidence of major cardiac events remained identical in both sexes (15.4 vs 15.7%: p = 0.43): cardiac mortality (3.2 vs 2%; p = 0.18), myocardial infarction (7.3 vs 6.7%; p = 0.37), further revascularisation (8.3 vs 7.2%; p = 0.47). The survival without major cardiac event was comparable at 1 year (87 +/- 0.1 vs 88 +/- 0.3%) and at 2 years (78 +/- 0.2 vs 83 +/- 0.3%; p = 0.58). In conclusion, the progression both in hospital and at two years with a strategy of early revascularisation for high risk acute coronary syndromes was comparable in males and females.
