Abstract: Objective To evaluate the effect of metabolic syndrome(MS)on prognosis of patients with cardiovascular diseases(CVD).Methods The data of 143 CVD patients including the age,waistline,blood pressure,body mass index(BMI),coronary arteriongraphy,ultrasound and blood glucoset,total cholesterol(TC),triglycerides(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),uric acid(UA),creatinine(Cr)were analyzed to detect the incidence of MS,the position and degree of coronary atherosclerosis,organ functional failure(OFF)and ventricular remodelling in the MS patients and those without MS.Results Of 143 CVD patients,72 cases(50.35%)were diagnosed with MS,and UA,Cr,waistline,systolic blood pressure(SBP),diastolic blood pressure(DBP),blood sugar,TG,body mass index(BMI),MS index,HDL-C,left ventricular end-systolic diameter(LVESD),ejection fraction(EF),left atrial dimension(LAD),interventricular septum thickness(IVST),posterior wall thickness(PWT),left ventricular mass(LVM),left ventricular mass index(LVMI),myocardial infraction(MI),stroke,cardia insufficiency,the position and degree of coronary atherosclerosis had difference between the patients with MS and without MS(P<0.05).Conclusion MS is a condition characterized by clustering of CVD risk factors.MS not only increases the incidence of CVD and OFF in the patients,but also effects the prognosis.
