RESUMO
INTRODUCTION: The coexistence of significant mitral regurgitation (MR) and severe aortic stenosis is prevalent, has a prognostic impact and makes treatment in the elderly population a complex issue. The aim of this study is to determine the prevalence of significant MR among a population of octogenarians and its influence on treatment and prognosis. METHODS: We used the data from PEGASO (Pronóstico de la Estenosis Grave Aórtica Sintomática del Octogenario), a prospective registry that consecutively included 928 patients aged ≥80â¯years with severe symptomatic aortic stenosis. RESULTS: The prevalence of significant MR was 8.5% (79 patients) and independently associated with the decision to treat conservatively (odds ratioâ¯=â¯2.28, 95% confidence interval: 1.31-3.95, pâ¯=â¯0.003). The group of patients with significant MR had higher overall mortality at 12â¯months follow-up (51.9% vs 25%, pâ¯<â¯0.001), which remained on division into subgroups based on the presence of comorbidities (Charlson<5: 49.2% vs 21.9%, pâ¯<â¯0.001; and Charlsonâ¯≥5: 62.5% vs 41.7%, pâ¯=â¯0.07). Within the group of patients in whom conservative treatment was performed, those with significant MR had higher mortality at one year (62.7% vs 35%, pâ¯<â¯0.001). MR was a significant independent predictor of overall mortality at 12-month follow-up (hazard ratioâ¯=â¯1.87, 95% confidence interval: 1.09-3.18, pâ¯=â¯0.022). CONCLUSIONS: Significant MR has a high prevalence and worsens the prognosis of octogenarian patients with severe symptomatic aortic stenosis, especially in patients with conservative treatment, independently of the existence of comorbidities.

BACKGROUND: Data on the cardiac characteristics of centenarians are scarce. Our aim was to describe electrocardiogram (ECG) and echocardiography in a cohort of centenarians and to correlate them with clinical data. METHODS: We used prospective multicenter registry of 118 centenarians (28 men) with a mean age of 101.5±1.7 years. Electrocardiogram was performed in 103 subjects (87.3%) and echocardiography in 100 (84.7%). All subjects underwent a follow-up for at least 6 months. RESULTS: Centenarians with abnormal ECG were less frequently females (72% vs 93%), had higher rates of previous consumption of tobacco (14% vs 0) and alcohol (24% vs 12%), and scored lower in the perception of health status (6.8±2.0 vs 8.3±6.8). Centenarians with significant abnormalities in echocardiography were less frequently able to walk 6 m (33% vs 54%). Atrial fibrillation/flutter was found in 27 subjects (26%). Mean left ventricular (LV) ejection fraction was 60.0±10.5%. Moderate or severe aortic valve stenosis was found in 16%, mitral valve regurgitation in 15%, and aortic valve regurgitation in 13%. Diastolic dysfunction was assessed in 79 subjects and was present in 55 (69.6%). Katz index and LV dilation were independently associated with the ability to walk 6 m. Age, Charlson and Katz indexes, and the presence of significant abnormalities in echocardiography were associated with mortality. CONCLUSIONS: Centenarians have frequent ECG alterations and abnormalities in echocardiography. More than one fifth has atrial fibrillation, and most have diastolic dysfunction. Left ventricular dilation was associated with the ability to walk 6 m. Significant abnormalities in echocardiography were associated with mortality.

BACKGROUND: The benefit from intervention in elderly patients with symptomatic severe aortic stenosis (AS) and high comorbidity is unknown. Our aims were to establish the correlation between the Charlson comorbidity index and the prognosis of octogenarians with symptomatic sever AS and to identify patients who might not benefit from intervention. METHODS: We used the data from PEGASO (Pronóstico de la Estenosis Grave Aórtica Sintomática del Octogenario--Prognosis of symptomatic severe aortic stenosis in octogenarians), a prospective registry that included consecutively 928 patients aged ≥ 80 years with severe symptomatic AS. RESULTS: The mean Charlson comorbidity index was 3.0 ± 1.7, a total of 151 patients (16.3%) presented high comorbidity (index ≥ 5). Median survival was lower for patients with high comorbidity than for those without (16.7 ± 1.2 vs. 26.5 ± 0.6 months, p < 0.001). In patients without high comorbidity planned interventional management was clearly associated with prognosis (log rank p < 0.001), which was not the case in patients with high comorbidity (log rank p > 0.10). In multivariate analysis, the only variables that were independently associated with prognosis were planned medical management and Charlson index. Patients with high comorbidity presented non-cardiac death more frequently than those who had not (28.6% vs. 19.5%, p = 0.008). CONCLUSIONS: One sixth of octogenarians with symptomatic severe AS have very high comorbidity (Charlson index ≥ 5). These patients have a poor prognosis in the short term and do not seem to benefit from interventional treatment.

BACKGROUND: The aim of the present study was to analyze whether absolute BNP and relative BNP change values during follow-up of elderly patients with chronic HF could predict the development of acute decompensated episodes. METHODS AND RESULTS: A total population of 108 elderly outpatients with the diagnosis of HF was retrospectively reviewed. Available BNP levels after at least one stable visit and one acute decompensated episode were required. Follow-up period was 12 months (343 visits, 42.6% decompensated HF episodes). Relative BNP changes were analyzed: "CC period" (patients who remained stable) and "CD period" (patient who suffered from a decompensated HF episode). Changes in BNP levels were significantly higher in CD than in CC periods (mean and median differences 138% and 85%, vs 16% and 0%, respectively; p<0.001). The clinical model (AUC=0.83) had a sensitivity of 67.06%, and a specificity of 80.36%. Relative BNP change (29%) showed by itself, a similar AUC (0.83) and specificity (79%) and an improved sensitivity (0.80) than the clinical model. When relative BNP change was introduced at the clinical model, a similar specificity was obtained and the diagnostic accuracy, AUC (0.89 vs 0.83, p=0.01) and sensitivity were improved. Absolute BNP changes showed worse AUC than that derived from relative BNP changes or clinical assessment. CONCLUSIONS: Percent BNP change values during the follow-up showed better results than absolute BNP values and improved the clinical assessment for diagnostic of decompensated HF episodes in elderly outpatients.
