Obesity is the strongest predictor of left atrial size in hypertensive men, highlighting its importance in the cardiac structural effects of hypertension.
Obesity may be a modifiable driver of LA enlargement in hypertension; leaves open causality and need for longitudinal outcome trials.
Obesity is the strongest predictor of LA size in patients with hypertension and amplifies the relation between LA size and LV mass. Race influences effects of age and hypertension on LA size. Because increased LA size and LV mass (also influenced by obesity) are associated with an adverse outcome, these findings underscore the importance of obesity, race and age with regard to the cardiac effects of hypertension.
