Combination of the Barthel Index at Discharge with GRACE Leads to Improved One-Year Mortality Prediction in Older Patients with Acute Myocardial Infarction.

Purpose: Many older patients with acute myocardial infarction (AMI) have impaired ability for activities of daily living (ADL). Impaired ADL leads to poor prognosis in elderly patients. The Global Registry of Acute Coronary Events (GRACE) score is widely used for risk stratification in AMI patients but does not consider physical performance, which is an important prognosis predictor for older adults. This study assessed whether the Barthel Index (BI) score combine the GRACE score would achieve improved one-year mortality prediction in older AMI patients. Patients and Methods: This single-center retrospective study included 688 AMI patients aged ≥65 years who were divided into an impaired ADL group (BI ≤60, n = 102) and a normal ADL group (BI >60, n = 586) based on BI scores at discharge. The participants were followed up for one year. Cox survival models were constructed for BI score, GRACE score, and BI score combined GRACE score for one-year mortality prediction. Results: Patients had a mean age of 76.29 ± 7.42 years, and 399 were men (58%). A lower BI score was associated with more years of hypertension and diabetes, less revascularization, longer hospital stays, and higher one-year mortality after discharge. Multivariable Cox regression analysis identified BI as a significant risk factor for one-year mortality in older AMI patients (HR 0.977, 95% CI, 0.963-0.992, P = 0.002). BI (0.774, 95% CI: 0.731-0.818) and GRACE (0.758, 95% CI: 0.704-0.812) scores had similar predictive power, but their combination outperformed either score alone (0.810, 95% CI: 0.770-0.851). Conclusion: BI at discharge is a significant risk factor for one-year mortality in older AMI patients, which can be better predicted by the combination of BI and GRACE scores.

Clinical features and treatment options for mitral regurgitation in elderly inpatients.

OBJECTIVE: To summarize clinical characteristics and treatment strategy of Chinese elderly mitral regurgitation (MR) inpatients under the current guidelines, and to identify factors related to treatment options in them. METHODS: A single center retrospective study was conducted in which patients hospitalized in Fuwai hospital from May 1st of 2014 to April 30 of 2015 with moderate to severe MR assessed by transthoracic echocardiography were enrolled consecutively (n = 1741). Patients > 60 years old were grouped as elderly group (n = 680) and patients < 60 years were grouped as control group (n = 1061). The elderly group was categorized into two subgroups based on surgical status. RESULT: s The mean age of the elderly group was 66.98 ± 5.94 years. The most common reason of MR in elderly group was degenerative MR (41.18%). Atherosclerotic risk factors such as hypertension, diabetes or hyperlipidaemia were more commonly observed in elderly group than the control group (45.44% vs. 25.17%, P < 0.001; 19.56% vs. 8.48%, P < 0.001; 35.29% vs. 19.51%, P < 0.001). Elderly group had higher EuroscoreIIscore (5.54 ± 2.42 vs. 3.15 ± 1.66), greater left ventricular end diastolic diameter (LVEDD) (57.72 ± 12.3 vs. 57.33 ± 10.19 mm) and a lower surgery rate (54.71% vs. 63.91%); P < 0.05. Age, left ventricular ejection fraction (LVEF), regurgitation grade, EuroScore-II high risk stratification and having diabetes were identified as factors associated with therapy decisions in elderly MR patients. CONCLUSIONS: Valve surgery was denied in 45.29% of elderly MR inpatients. Older age, impaired LVEF, lower regurgitation grade, EuroScore-II high risk stratification, and having diabetes were factors most significantly associated with surgery denial among elderly Chinese inpatients with MR.
