RESUMO
Objective:To observe the clinical characteristics of female patients with ST-segment elevation myocardial infarction (STEMI) complicated with multivessel disease (MVD) undergoing direct percutaneous coronary intervention (PCI), and to explore the factors affecting the prognosis of female patients.Methods:In this retrospective cohort study. 1 033 patients (196 women) with STEMI combined with MVD who were admitted to our hospital from 2005 to 2015 and successful completed direct PCI within 24 h onset of symptom were enrolled. Patients’ baseline data, PCI data and follow-up results were recorded. Kaplan-Meier method was used to plot the survival curve. Cox regression model was used to screen the prognostic factors of STEMI patients with multivessel disease.Results:Compared with male patients, the age of female patients was significantly older, while the proportion of smoking history, family history of coronary heart disease, and stent implantation history was significantly lower, the time from onset to PCI was significantly longer, and the proportion of intraoperative slow blood flow/no-reflow was significantly higher among female patients. The mean follow-up time was 4 years, and the incidence of major adverse cardiovascular events (MACE) was higher in women than in men. The main factor affecting the prognosis of female patients was Killip cardiac function grade Ⅱ~Ⅳ ( HR=1.804, 95% CI: 1.060~3.071, P<0.05). The number of lesions with >50% occlusion ( HR=1.808, 95% CI 1.123-2.912, P < 0.01) was a common risk factor for both men and women. Conclusions:Compared with male patients, there is more treatment delay among female patients with STEMI and MVD, the incidence of MACE is higher, and cardiac insufficiency is the main factor affecting the prognosis of female patients.
RESUMO
Objective To observe the effect of tirofiban,aspirin and Clopidogrel Hydrogen triple antiplatelet in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention and the effect on the incidence of major adverse cardiac events.Methods a total of 60 patients with acute myocardial infarction(AMI)in our hospital from January 2015 to-2016 in December were enrolled in this study.All patients were treated with percutaneous coronary intervention(PCI).The patients were randomly divided into control group(n=30)and observation group(n=30).The control group using clopidogrel hydrogen treatment,observation group were treated with tirofiban,aspirin and Clopidogrel Hydrogen triple antiplatelet therapy,the incidence and clinical effects of the two groups of major adverse cardiac events.Results the two groups before treatment,the platelet aggregation rate and platelet count had no statistically significant difference; no significant observation group after treatment compared 30d platelet count difference; observation group 30d after treatment,the platelet aggregation rate was lower than the control group(P<0.05); the observation group after the treatment of 30d MA-ADP on platelet drug reaction the inhibition rate is lower than the control group(P<0.05); the observation group after treatment of AA drugs 30d platelet inhibition rate,the inhibition rate of ADP,higher than that of the control group(P<0.05); the observation group after treatment,the incidence of major adverse cardiac events was 13.33％,33.33％in the control group,two groups of major adverse cardiac events was statistically significant the difference(P<0.05).Conclusion The patients with acute myocardial infarction undergoing primary percutaneous coronary intervention after treatment with tirofiban,aspirin and chlorine Pigre triple antiplatelet ideal treatment effect,can reduce the incidence of major adverse cardiac events,it is worthy of popularization and application.
RESUMO
Objective To investigate the clinical characteristics and risk factors of non-premature STEMI patients underwentprimaryPCI with multivessel disease.Methods Data of clinic and coronary angiographic features were retrospectively compared between group of 371 younger STEMI patients (male age ＜ 55 years,female ＜ 65 years) and group of 662 older STEMI patients.All patients were admitted to hospital from January 2005 to January 2015 and treated with primary PCI.The patients' gender,smoking history,family history of coronary heart disease (CHD),hypertension,type 2 diabetes mellitus,previous myocardial infarction and revascularization,stroke history,serum uric acid,lipids etc.were documented.The comparison of coronary artery disease characteristics and the incidence of adverse events during hospitalization were also carried out between two groups.Results (1) Prevalence of males (88.4％ vs.76.9％),smokers (74.9％ vs.51.5％),family history of CHD (21.0％ vs.9.7％) and levels of diastolic blood pressure,total cholesterol,low density lipoprotein cholesterol (LDL-c),triglycefides,and low cholesterol were significantly higher in the non-prematuregroup than in the premature group (all P ＜ 0.01),while high density lipoprotein cholesterol (HDL-c) was lower in non-prematuregroup (P ＜ 0.01).(2) The incidence of in-hospital events in both groups were low.There was less ventricular tachycardia in the non-premature group (1.5％ vs.0.3％) (P＜0.05).(3) There were no statistically significant differences in the number of infarct vessels,site ofinfarctbetween two groups.(4) Logistic regression analysis showed that smoking (OR =2.22,95％ CI:1.588-3.108) (P ＜ 0.05),family history of CHD (OR=2.12,95％CI:1.431-3.140) (P＜0.05),triglyceride concentration (OR=1.971,95％CI:1.475-2.635) (P＜0.05),LDL-c (OR=1.193,95％CI:1.008-1.413) (P=0.04) were independent risk factors fornon-premature STEMI withmultivessel disease.Conclusion Smoking,family history of CHD,triglyceride concentration,LDL are main risk factors of younger age STEMI patients with multiple vessel disease;Compared with younger age patients,older age patients during hospitalization are more likely to occur ventricular tachycardia.Regardless of age difference,the characteristics of coronary artery lesions show no significant difference.
