Abstract
Objective To explore the correlation between the level of hematocrit (HCT) of the patients with acute myocardial infarction (AMI) shortly after admission and the heart failure (HF) after percutaneous coronary intervention (PCI).Methods The clinical data of 872 patients with AMI undergoing emergent PCI hospitalized during the period from Jan.,2010 to Dec.,2010 were collected and 872 patients were divided into 3 groups according to the level of HCT detected at admission:anemia group (n =229,HCT ＜ 39 ％ for men and HCT ＜ 36 ％ for women),normal group (n =600) and erythrocytosis group (n=43,HCT＞47％ for men and HCT＞46％ for women);follow-up lasted for 65 months;a comparative study was made to the occurrence of cardiovascular events during follow-up among the groups.Results The comparison of the general clinical data at admission showed that there existed a statistical difference in age,low-density lipoprotein (LDL-C),total cholesterol (TC),triglycerides (TG),sex,smoking history,ST-elevation and dialysis history (P＜0.05);the occurrence of heart failure 65 months after operation was of obvious difference among the 3 groups (P＜0.01),the occurrence in anemia group was greatly different from that in normal group (P＜0.01);binary logistic regression analysis was made with the adjustment of age,smoking history and hyperlipidaemia and the result indicated that HCT was the independent predictor of HF occurrence 65 months after PCI in patients with AMI (r=4.466,P＜0.05).Conclusions HF occurrence in patients with low level of HCT after admission is high,which may be the predictor of the occurrence of cardiovascular events in patients with AMI 5 years after PCI.关键词
