RESUMO
OBJECTIVES: To evaluate whether carotid disease is associated with coronary artery disease (CAD) extension in patients undergoing treadmill exercise stress echocardiography (EE). METHODS: We retrospectively studied 156 patients without previous vascular disease who underwent EE, carotid ultrasonography, and coronary angiography between 2002 and 2013. Low-, intermediate-, and high-risk EE were defined as negative, localized ischemia, and multivessel/extensive ischemia EE respectively; carotid disease according to Mannheim and American Society of Echocardiography Consensus and CAD extension from zero to three vessel disease as stenosis ≥50% by visual assessment. RESULTS: Of the 156 patients, 67 (42.9%), 43 (27.6%), 22 (14.1%), and 24 (15.4%) had zero, one, two, and three vessel disease respectively. Age (P = 0.047), male sex (P = 0.010), diabetes mellitus (P = 0.039), smoking habit (P = 0.015), fasting plasma glucose (P = 0.021), European Systematic COronary Risk Evaluation (P = 0.003), pretest CAD probability (P = 0.003), high-risk EE (P < 0.001), and carotid plaque presence (CP) (P < 0.001) were associated in univariate analysis with more extensive CAD. Predictors of CAD extension in multivariate analysis were high-risk EE (odds ratio [OR] 2.42, P < 0.001), CP presence (OR 1.75, P = 0.004), and pretest CAD probability >65% (OR 1.49, P = 0.023). CP was also associated with multivessel CAD in the 53 patients with low- or intermediate-risk EE (P = 0.001). CONCLUSIONS: CP is associated with CAD extension in patients with ischemic heart disease suspicion undergoing EE. Patients with CP could benefit from a more aggressive therapeutic strategy regarding patients without carotid disease and similar risk EE, especially in intermediate- and/or low-risk test where guidelines recommend initially optimal medical treatment.

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.
