ABSTRACT
ObjectiveTo analyze hospitalized death related factors in elderly patients with nonST-segment elevation myocardial infarction (NSTEMI). MethodsThree hundred and two patients (≥65 years old) with NSTEMI were included. Thirty-two patients of them died in hospital (death group). Their clinical data were retrospectively analyzed and correlated factors for in-hospital death were evaluated. ResultsCompared with survival group, patients in death group were more likely to have 3 or more chronic diseases,heart function killip grades Ⅲ- Ⅳ, heart rate＞ 100/min and peripheral blood WBC count＞10X 10＜'9＞/L on admission (all P＜:0.05). There was no significant difference in fasting plasma glucose level and serum creatinine on admission between the two groups (both P:＞0.05). But after glomerular filtration rate(eGFR) were estimated by the modified abbreviated MDRD equations based on the Chinese CKD patients, patients in death group were more likely to be with renal dysfunction and pulmonary infection (both P＜0.01 ). Multiple logistic regression analysis showed that heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR, pulmonary infection on admission were the independent predictors for in-hospital death in elderly patients with NSTEMI. ConclusionsCoexistence of 3 or more chronic diseases is a related factor of death and heart function killip grades Ⅲ-Ⅳ, renal dysfunction evaluated by eGFR and pulmonary infection are the independent predictors for in-hospital death in elderly patients with NSTEMI.
