ABSTRACT
Objective: To summarize the clinical features and treatment status for elderly in-hospital patients with mitral regurgitation (MR). Methods: A single center retrospective study was conducted in 1 741 patients admitted in our hospital from 2014-05-01 to 2015-04-30 with echocardiography confirmed moderate to severe MR. The patients were divided into 2 groups: Elderly group, n=680(39.06%)patients≥60 years of age and Non-elderly group,n=1 061(60.94%)patients<60 years.Clinical features and treatment status were studied and compared between 2 groups. Results: The mean age in Elderly group was (66.98±5.94) years and the most common type was degenerative MR (41.18%). Compared with Non-elderly group, Elderly group had more patients combining coronary artery disease (37.79% vs 17.43% ), more risk factors of atherosclerosis such as hypertension (45.44% vs 25.17%), diabetes (19.56% vs 8.48%) and hyperglycemia (35.29% vs 19.51%) all P<0.05; Elderly group had the higher EuroSCORE Ⅱ score (5.54±2.42) vs (3.15±1.66), greater left ventricular end diastolic diameter (57.72±12.37) mm vs (57.33±10.19) mm and less patients combining multiple valve disease (35.59% vs 40.81%), less patients received surgical treatment (54.71% vs 63.9%), all P<0.05. The surgery procedures (mitral valve replacement or mitral-plasty) were similar between 2 groups; compared with Non-elderly group, Elderly group had the higher application rate of bio-prosthetic valve (53.88% vs 18.67%), P<0.001. Conclusion: About 40% in-hospital moderate to severe MR patients were the elderly crowd, the most common pathogenesis was degenerative changes which leaded the higher incidences of cardiac complications, worse cardiac function and the higher risk scores for surgical treatment, there were less patients received surgery.
