Abstract:
Objective: To analyze the risk factors affecting prognosis of calciifc aortic stenosis in patients elder than 75 years of age and to compare the safety among different treatments. Methods: A total of 421 consecutive aortic stenosispatients treated in our hospital from 2008-01-01 to 2015-01-01 were retrospectively studied. The patients were at the age of (79.1 ± 3.5) years and with 243 (57.7%) of male gender. According to echocardiography data, the patients were divided into 3 groups: Mild stenosis group,n=112, Moderate stenosis group,n=83 and Severe stenosis group,n=226. All patients were followed-up for 1 year to observe the end point of all cause and cardiac death. In Severe stenosis group, mortalities by different treatments were compared; the risk factors related to death were calculated by Logistic regression analysis. Results: The overall 1 year all cause and cardiac mortalities were 22.3% (94/421) and 19.7% (83/421) respectively, both all cause and cardiac mortalities were similar among 3 groups,P>0.05. Multivariate Logistic regression analysis indicated that peripheral vascular disease (OR=2.31, 95% CI 1.215-4.392), LVEF (OR=0.966, 95% CI 0.942-0.991) and NT-proBNP (OR=2.022, 95% CI 1.140-3.586) were the independent risk factors for 1 year all cause death; diabetes (OR=2.157, 95% CI 1.213-3.836), LVEF (OR=0.975, 95% CI 0.950-1.000), NT-proBNP (OR=2.786, 95% CI 1.449-5.356) and blood levels of phosphorus (OR=5.755, 95% CI 1.462-22.657) were the independent risk factors for 1 year cardiac death. In Severe stenosis group, the all cause mortalities by medication, PBAV, TAVR and SAVR were 43.6%, 57.1%, 7.3% and 6.45% respectively, the patients with TAVR, SAVR had the lower mortality than those with medication, P<0.0001, while the mortality was similar between the patients with TAVR and SAVR, P>0.05. Conclusion: All cause and cardiac mortalities within 1 year were increasing with the age accordingly, while aortic stenosis grade was not related to mortality in elder patients with calcific aortic stenosis. Peripheral vascular disease and blood levels of phosphorus were the risk factors affecting prognosis. TAVR and SAVR had better effect for treating the patients with severe aortic stenosis.
