Centenarians and their hearts: A prospective registry with comprehensive geriatric assessment, electrocardiogram, echocardiography, and follow-up.

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.

INTRODUCTION AND OBJECTIVES: Multiple clinical and echocardiographic parameters have been shown to have prognostic value in cases of left ventricular dysfunction. The purpose of this paper was to evaluate the relative predictive power of such parameters. METHODS: Ninety-one patients with systolic dysfunction were prospectively studied. Functional status was evaluated using the New York Heart Association classification and the 6-minute walking test. Other clinical and biochemical parameters were assessed, and an anatomic and functional echocardiographic study was performed. RESULTS: Mean follow-up was 16.5 months (SD: 6.95). Eighteen patients died and two underwent heart transplantation (cardiac death 22%). Multiple regression analysis showed that the only independent predictor of death was functional status. Functional classes I and II showed a 16-month mortality rate of 10%, class III 40% and class IV 83%. The mortality rate was 67% for patients who walked < 300 meters and 0% for those who reached > 500 meters. When echocardiographic results were analyzed separately, the only independent predictors of outcome were left atrial diameter and the E wave deceleration time. Deceleration times < 100 ms or atrial diameters > 5 cm were associated with a mortality rate of 46%. The correlation between E wave deceleration time and the walking test was r = 0.55, p < 0.0001. CONCLUSIONS: Functional status is the main predictor of outcome in patients with systolic dysfunction, whether assessed subjectively or estimated objectively by a walking test. Among echo-Doppler parameters, the deceleration time of the E wave and left atrial diameter gave similar prognostic information, although with less statistical significance. They can confirm or substitute the prognosis obtained by the functional classification.
