Abstract
Background: Heart failure poses an increasingly significant medical and economic burden. Management options and additional diagnostic testing is contingent upon determining the LV systolic and diastolic function. A rapid, non invasive tool to accurately distinguish systolic from diastolic dysfunction would be valued. We tested the ability of an FDA-approved radial tonometry device (Sphygmocor; AtCor Medical Corp; Sydney, Australia) for this novel purpose. Methods: 73 randomly selected patients evaluated with echocardiography underwent simultaneous radial artery tonometry.
