Abstract：Objective To explore the differences in risk factors, related medical history, and hospital mortality between patients of different ages, different sexes, and patients with acute myocardial infarction (AMI) in different regions. Methods A total of 550 AMI patients were selected from Fuxin Central Hospital and Beipiao Central Hospital between January 2015 to December 2015, including 321 males and 199 females. Clinical data such as patient general condition, risk factors, related medical history, discharge diagnosis and hospital adverse cardiovascular events were collected. Results Group of age≥75 years old had the highest proportion of AMI. Group of age <55 years old had the highest proportion of males with AMI. Group of age ≥75 years old had the highest proportion of females with AMI. Age and the proportion of AMI was positively correlated (P<0.05). The incidence of AMI in males is higher than that in females. There were more females than males with respect to history of hypertension and diabetes, and more males than females with respect to history of smoking (P<0.05). In the 55-year-old group, there was a higher proportion of patients with a history of smoking. The abnormal rate of dyslipidemia in patients with AMI in Fuxin area was higher than that in Beipiao area (P<0.05). The history of ischemic stroke in Fuxin area was lower than that of Beipiao (P<0.05). The number of ST-elevated myocardial infarction (STEMI) patients was higher than number of non ST-elevated myocardial infarction (NSTEMI) patients. Lower wall myocardial infarction and anterior myocardial infarction (including anterior wall, anterior wall, extensive anterior wall) higher incidence. The hospital mortality rate of STEMI was higher than NSTEMI (all P<0.05). Conclusion Group of age ≥75 years old had the highest proportion of AMI. The male AMI patients had become younger. The incidence of AMI increases with age. The incidence of AMI in males was higher than that in females. AMI patients of different genders and regions had different proportions of risk factors and related medical history. The incidence of different infarction sites and the proportion of in-hospital deaths were different. STEMI cases were more than NSTEMI. The incidence of inferior myocardial infarction was the highest. The proportion of in-hospital deaths in patients with STEMI was higher than in patients with NSTEMI.
