Cardiopulmonary Exercise Testing Variables Reflect the Degree of diastolic Dysfunction in Patients With Heart Failure Normal Ejection Fraction Marco Guazzi, MD, PhD, Jonathan Myers, PhD, Mary Ann Peberdy, MD, Daniel Bensimhon, MD, Paul Chase, MEd, and Ross Arena, PhD, PT. PURPOSE: Previous investigations have reported a relationship between K E Y W O R D S. Variables obtained from echocardiography with tissue Doppler imaging (TDI) and Cardiopulmonary Exercise Testing (CPX) in systolic diastolic function heart failure (HF) cohorts. The purpose of the present investigation was to perform a comparative analysis between echocardiography heart rate recovery with TDI and CPX in patients with HF and normal ejection fraction ventilatory expired gas (NEF). METHODS: Patients with HF-NEF (N 32) underwent echocardiography with TDI and CPX to determine the following Variables : (1) the ratio between mitral early velocity (E ) and mitral annular velocity (E ), (2) Author Affiliations: Cardiology ejection fraction, (3) left ventricular (LV) mass, (4) left ventricular end Division, University of Milano, San systolic volume, (5) peak oxygen uptake ( V O2), (6) ventilatory efficien- Paolo Hospital, Milano, Italy cy, (7) the partial pressure of end-ti
