Abstract:
Objective To compare the clinical characteristics and long?term prognosis between male and female patients with premature coronary artery disease (PCAD) post coronary intervention, and analyse the risk factors of major adverse cardio?cerebrovascular events (MACCE) and bleeding events. Methods This was a prospective single?center observational study. From January 2013 to December 2013, 4 744 patients diagnosed as PCAD and treated with percutaneous coronary intervention (PCI) in Fuwai Hospital were enrolled. The general clinical data, laboratory results and interventional treatment data of all patients were collected, and patients were followed up for 2 years after PCI and the incidence of events including MACCE and bleeding was analyzed. The baseline data and clinical events of PCAD patients of different genders were compared. Survival curves were estimated by Kaplan?Meier method. Univariate and multivariate Cox regression were used to analyze whether gender was an influencing factor of different clinical events of PCAD patients within 2 years after PCI, and other relevant influencing factors of MACCE and bleeding events. Results Among the 4 744 PCAD patients included, there were 3 390 (71.5%) male aged (47.0 ± 5.4) years old and 1 354 (28.5%) female aged (57.0 ± 5.8) years old. Compared with female patients, male patients had higher body mass index, higher proportion of hyperlipidemia, smoking, myocardial infarction, previous PCI, preoperative estimated glomerular filtration rate, ST?segment elevation myocardial infarction, radial artery approach, intravenous ultrasound use and chronic occlusive lesions (all P<0.05). Age, left ventricular ejection fraction, prevalence of hypertension, diabetes mellitus, past stroke history, non?ST?segment elevation acute coronary syndrome (NSTE?ACS) and the use of calcium channel blockers were lower in male patients than in female patients (all P<0.05). The 2?year follow?up results showed that the incidence of BARC type 1 hemorrhage was significantly higher in female patients than in male patients (6.9%(92/1 343) vs. 3.7%(126/3 378), P<0.001); however, the incidence of MACCE, all?cause death, cardiac death, recurrent myocardial infarction, revascularization (target vessel revascularization and target lesion revascularization), stent thrombosis, stroke and BARC type 2-5 hemorrhage were similar between the two groups (all P>0.05). Multivariate Cox regression analysis showed that gender was an independent risk factor for BARC type 1 bleeding in PCAD patients ( HR=2.180, 95%CI 1.392-3.416, P<0.001), but it was not an independent risk factor for MACCE and BARC type 2-5 bleeding(all P>0.05). Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE?ACS were the independent risk factors for MACCE in PCAD patients with PCI (the HRs (95% CI ) were 1.289(1.052-1.580), 1.030 (1.019-1.042), 1.758(1.365-2.264), 1.264(1.040-1.537), respectively); gender (HR=1.579, 95%CI 1.085-2.297, P=0.017), hyperlipidemia ( HR=1.305, 95%CI 1.005-1.695, P=0.046), anticoagulant drugs including low molecular weight heparin (HR=1.321, 95%CI 1.002-1.741, P=0.048) or sulfonate(HR=1.659, 95%CI 1.198-2.298, P=0.002) were the independent risk factors for bleeding events. Conclusions There are differences in clinical and coronary artery lesion characteristics between different genders in patients with PCAD. The incidence of minor bleeding is significantly higher in female PCAD patients than in male PCAD patients. Hyperlipidemia, preoperative SYNTAX score, multivessel lesions and NSTE?ACS are the independent risk factors for MACCE, and gender, hyperlipidemia, anticoagulant drugs including low molecular weight heparin or sulfonate are the independent risk factors for bleeding events in patients with PCAD.
