TL;DR: The age-adjusted incidence of AF increased significantly in Olmsted County during 1980 to 2000 and the projected number of persons with AF for the United States will exceed 10 million by 2050, underscoring the urgent need for primary prevention strategies against AF development.

TL;DR: (ICT+IRT)/ET is a conceptually new, simple and reproducible Doppler index of combined systolic and diastolic myocardial performance in patients with primarymyocardial systols dysfunction and was easily measured, reproducible, and had a narrow range in normals.

TL;DR: In this article, a prospective study of 140 adults, referred for a clinically-indicated echocardiogram and in sinus rhythm, with no history of atrial arrhythmias or valvular heart disease, determined the left atrial (LA) volume, LV diastolic function status, cardiovascular risk score, and cardiovascular disease burden (based on confirmed vascular disease, congestive heart failure, and transient ischemic attack or stroke).

TL;DR: The normal size and phasic function of the left atrium is discussed, the clinically important aspects and pitfalls of evaluating LA size, and the methods for assessing LA function using echocardiography are outlined.
