Why the study?
Does echocardiographically defined LA diameter predict cardiovascular death in middle-aged men?
Does echocardiographically defined LA diameter predict cardiovascular death in middle-aged men?
Echocardiographically defined left atrial enlargement is directly associated with an increased risk of cardiovascular death in middle-aged men.
Answers are grounded in this paper and cite their sources.
LA diameter may identify higher CV death risk in middle-aged men; leaves open incremental value over standard predictors.
This prospective population-based study shows that echocardiographically defined LA diameter was directly related to the risk of cardiovascular death. The association of LA enlargement to cardiovascular death appears to be partially related to LV hypertrophy.
