Left Atrial Volume, Geometry, and Function in Systolic and Diastolic Heart Failure of Persons ≥65 Years of Age (The Cardiovascular Health Study)

摘要: The left atrium enlarges in association with many factors, including aging, atrial fibrillation, hypertension, diastolic dysfunction, and heart failure (HF) low ejection fraction. However, (LA) volume, geometry, emptying have not been compared between systolic HF, nor has the of LA volume for new HF determined older subjects, whom normal We used echocardiography to measure 851 community-dwelling subjects ≥65 years age, 180 at baseline 255 participants who subsequently developed HF. area, linear dimensions were higher prevalent incident groups than controls did differ those versus independent co-morbidities Doppler measures function. fractional area change was associated prevalent, but incident, In conclusion, population-based size is increased decreased patients either or development These findings highlight important role without a
