Clinical characteristics and outcome comparison between young (< or = 45 years) female and male patients with coronary artery disease undergoing percutaneous coronary intervention / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical characteristics and clinical outcomes in young (< / = 45 years) female and male coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>Angiographic and clinical data from 124 premenopausal female patients who underwent elective PCI from April 2004 to February 2008 were compared to age-matched 430 male patients who underwent elective PCI between 2006 and 2007 in our department. All patients were treated according to guidelines and coronary angiography was repeated after 6 months. One year clinical follow-up were performed in all patients.</p><p><b>RESULTS</b>Incidences of dyslipidemia, the history of myocardial infarction and smoking were significantly lower in female patients than in male patients (all P < 0.01). Left main, left anterior descending and bifurcation lesions were more common while type C lesion and right coronary lesion were less common in young female CAD group compared to young male CAD group (P < 0.01-0.05). The average lesion length in female patients was significantly longer than that in male patients [(20.36 +/- 13.37) mm vs. (23.04 +/- 13.86) mm, P < 0.05]. The in-hospital and follow-up incidences of major adverse cardiac events, stent thrombosis and in-stent restenosis were similar between young female and male CAD patients.</p><p><b>CONCLUSIONS</b>CAD risk factors were less and vessel lesions were more likely to be found at left main, left anterior descending and bifurcation in young female CAD patients compared to young male CAD patients. The clinical outcomes were similar between young female and male CAD patients.</p>
