Comparative Observations Of Clinical Characteristics In Hospital Patients With AMI In The Hunchun Area

Objective: The purpose of the present study was to investigate the clinicalcharacteristics and the risk factors of the female Acute Myocardial Infraction (AMI)patients compared to male AMI patients in the Hunchun area, in order to improve thetreatment and prevention of the diseases in female patients. Methods: Weselected the clinical data received from the Hunchun City Hospital and HunchunCity Chinese Traditional Hospital. A total of 356 AMI patient cases(231 male/125female)between January 2000 and December 2006,were used in this study. Clinicalcharacteristics,risk factors for the disease,the infarction mortality rate, and thesocio-economic factors, according to gender, were considered. Significantdifferences were compared using Student's T-test. Unpaired data and the classifiedvariable data were compared by Chi-Square test. Statistical significance, was definedas P＜0.05. The results were given as Means±SD. Results:①The averageage of female patients was 64.87 years old (±11.14 years)where the average age ofmale patients was 59.14 years old(±12.67 years). The peak age of female patientswhen AMI was first diagnosed was between 61-70 years and the peak for males was51-60 years. The age of female patients with AMI disease appears to be 10 yearslater than male patients.②With relation to the traditional risk factors ofsmoking and hypercholesterolemia, there were significant differences by Chi-Squaretest between the two groups of AMI patients (P＜0.05). There were no significantdifferences with diabetes and hypertensive disease between the two groups of AMIpatients (P＞0.05).③There were significant difference with no chest pain betweenfemale patients(48.00%) and male patients (16.88%)(P＜0.05).④Cardiacinsufficiency of the female AMI group was significantly different compared with themales (72.80% and 45.45%, respectively, P＜0.01). There were between the twogroups of AMI patients (91.20% and 95.24%; 21.60% and 24.24%, respectively, P＞0.05).⑤There were no significant differences with the position of AMI between the two groups of female and male AMI patients (P＞0.05).⑥The infarction mortalityrate in females (32.00%) was significantly higher than that Of males (9.96%) (P＜0.05). In the＜45 years of age group and the 45-54years of age group, theinfarction mortality rate in AMI patients showed no significant differences (P＞0.05).In the 55-64 years old group and the≥65 years old group, there were significantdifferences (P＜0.05).⑦In the 55-64 years old group and the≥65 years oldgroup, there were significant differences with the cluster of risk factors in the group ofAMI patients (P＜0.05).⑧The female AMI patients who were automaticallydischarged from the hospital due to financial difficulties comparedwith the male ones have significant differences (females-37.64%/males-13.94%, P＜0.05). Conclution:①The AMI mortality rate in femalesof the Hunchun area was significantly higher than that Of males,which wassignificantly higher with growing age.②The proportion of cardiac insufficiency of thefemale AMI group in Hunchun area were higher than that of males with seriouscondition, poor prognosis.③After menopause and the cluster of risk factors are themain reason of higher mortality in the female AMI patients of Hunchun areacomepared with the male ones.④Socio-economic factors had made a more notableimpact on the female AMI patients of Hunchun area than the male ones.
