Left ventricular apical rotation is related to ambulatory blood pressure and body mass in healthy elderly females

Abstract

In healthy elderly females, there seems to be an interaction between LV apical rotation, BP and body mass. Peak apical rotation and peak diastolic rotation velocity correlate with indices of LV filling and ejection, indicating that suction, a crucial element for effective early LV filling, may be preserved in healthy elderly subjects. Suction deteriorates with elevations of the arterial BP. An age- and BP-related reduction in LV end-diastolic volume may represent an additional impediment to LV filling. Both features may contribute to the development of LV diastolic dysfunction and to episodes of diastolic heart failure.
