Clustering Status Of Main Coronary Heart Disease Risk Factors In AMI Patients With Different Age And Gender

Objective:To investigate the clustering status of main risk factors in Acute myocardialinfarction patients with different age and gender.Methods:The study covered1420patients with the diagnosis of Acute Myocardial Infarctionadmitted in CCU from January2010to December2012in the First Affiliate Hospital ofDalian Medical University. Based on gender, all patients were divided into two groups:male group and female group. Based on age, all patients were divided into three groups:youth group(＜45years), middle-aged group(45~64years) and elderly group(≥65years). Compare the differences of main coronary heart disease risk factors among thesegroups.Results:1. Compared with male, the average age of female patients to suffer AMI was nineyears later. In the male group, cigarette smoking was the main risk factor(66.2%), whilethe rate of hypertension, dyslipidemia and diabetes mellitus in the female group weresignificantly higher than those in the male group（68.5%vs53.4%,51.8%vs42.4%,37.0%vs27.5%respectively, all P＜0.01).2. The aggregation of risk factors for male mainly included cigarette smoking, dyslipidemia and hypertension, while for female patients it mainly includeddyslipidemia, hypertension and diabetes mellitus.3. Male, cigarette smoking, and dyslipidemia were the main risk factors in theyouth group, the rate were96.6%,70.5%and65.9%respectively, the rate ofhypertension, diabetes mellitus and family history were low(43.2%,25.0%and13.6%respectively); in the middle-aged group, we found the similar results; hypertension anddiabetes mellitus were the main risk factors in the elderly group, the rate of these twowere significantly higher than those in the other two groups (compared with the youthgroup:60.7%vs43.5%and32.8%vs11.8%respectively; compared with themiddle-aged group:60.7%vs49.7%and32.8%vs26.1%respectively. all P＜0.01).4. Young patients mainly had two risk factors, the rate was46.6%, whilenon-young patients usually had two and three risk factors: in the middle-aged group, therate were31.2%and31.6%respectively; in the elderly group, the rate were32.8%and37.7%respectively.5. There were1055male and365female patients of all, the rate were74.3%and25.7%respectively. In the male group, cigarette smoking was the main CHD risk factorsfor young AMI patients, while hypertension was the main CHD risk factors for oldpeople. In the female group, hypertension and dyslipidemia were the main risk factorsin the non-young female patients, the rate of hypertension in middle-aged femalepatients was significantly higher than old women (71.1%vs60.2%, P＜0.01).Conclusion：1. Female patients with acute myocardial infarction were significantly older thanmen. The aggregation of risk factors for male mainly included cigarette smoking,dyslipidemia and hypertension, while for female patients it mainly includeddyslipidemia, hypertension and diabetes mellitus.2. Young AMI patients were mainly male. Cigarette smoking, dyslipidemia andfamily history were the main CHD risk factors for young AMI patients, hypertensionand diabetes mellitus were the main CHD risk factors for old people.3. There was aggregation of variable cardiovascular risk factors in each group and moreAMI patients usually had two or more CHD risk factors.4. To control the risk factors, young population should quit smoking and reducelipid, while the old population should control the blood pressure and plasma glucose.
