Abstract:
Objective To analyze causes of death and risk factors of acute myocardial infarction(AMI)、Methotis 118 AMI patients who died f selected from 1252 hospitalized patients with AMI from January 2003 to June 2008)were retrospectively enrolled for analysis of risk factors and death causes.Resuits The overall mortality of hospitalized patients with AMI was 9.42%(118/1252).The mortality rate in the males was 8.91%(84/943)while in the females was 11.00%(34/309)which was higher than the males but there was no statistical difieFence (P=0.2739).Mortality rate rose along with age and showed significant statistical difference(P＜0.0001)among different age group[＜40 yrs:6.45%(2/31),40～54:2.56%(6/234),55～64:5.11%(16/313),≥65:13.95%(94/674)].Pump failure occurred in 77 cases(65.25%)which was the main cause of death,cardiac arrest occurred in 21 cases(17.80%)and heart rupture in 13 cases(11.02%).There existed other causes of death including cerebral hemorrhage.digestive tract bleeding and pneumonia in 7 cases(5.93%).The mortality of patients with PCI was 4.24%(39/920)while23.80%(79/332)of those witbout PCI(P＜0.0001).Rate of cardiac rupture was 1.04%(13/1252),2.91%(9/309)in females and 0.42%(4/943)in males(P＜0.0001).The time was＜24 h(23.72%.28/118)when death occurred from onset,24 h～1 week(55.93%,66/118)and 1～4 week (20.34%,24/118).There was no statistical difference of mortality related to different infarction locations[antior 12.47%(59/473),anteroseptal 9.23%(12/130),inferior 6.73%(28/416),lateral 8.70%(4/46),ventricle postwall 5.97%(4/67),and ST-segmental elevated myocardial infarction 9.17%(11/120)(P=0.0852)].Conclusions There is a high mortality in aged patients with AMl with heart failure as the most common cause of death which usually occurs at early stage of AMI.The females have more cardiac ruptures than the males.PCI significantly decreases rates of mortality and cardiac rupture.Moreover.gender and location of AMI might be another important risk factor which affect mortality.
