Influence of Left Ventricular Stroke Volume on Incident Heart Failure in a Population with Preserved Ejection Fraction (From the Strong Heart Study)

At a given level of left ventricular (LV) systolic function, LV pump performance (assessed by stroke index [SVi]) may differ, depending on LV size. We evaluated whether low SVi may be considered a marker of risk for incident congestive heart failure (HF), independent of LV geometry and systolic function, assessed by ejection fraction (EF) or midwall fractional shortening (MFS), in a large population-based sample with normal EF. Clinical and echocardiographic data from the second Strong Heart Study (SHS) exam, including 2,885 American Indians (59 ±8 years; 63% women) with normal EF (EF≥51% in men and EF≥55% in women) and without prevalent HF or significant valve disease, were analyzed.
