Background Increasing diastolic dysfunction (DD) grade is associated with increased heart failure (HF). Patients with preserved ejection fractions and grade 1 DD may have left atrial dilatation, e′ < 8 cm/sec, increased left ventricular (LV) mass, or variable E/e′ ratios. The aim of this study was to test the hypothesis that LV hypertrophy or E/e′ ratio > 8 may be associated with a greater incidence of HF. Methods Two hundred twelve patients with grade 1 DD and ejection fractions > 50% were retrospectively studied. Group 1 comprised 108 patients with E/A ratios < 0.8, without LV hypertrophy, e′ < 8 cm/sec, and E/e′ ratios < 8. Group 2 comprised 104 patients with LV hypertrophy or E/e′ ratios > 8. Patients with incident HF and valvular or coronary disease were excluded. Using two-dimensional Doppler echocardiography, LV and left atrial volumes and transmitral spectral and tissue Doppler were analyzed. Medical records were examined for laboratory data, HF admissions, and all-cause mortality from 2004 to 2012. Results Despite similar ejection fractions, patients in group 2 had greater LV and left atrial volumes, LV mass index values, and E/e′ ratios (P < .01 for all). HF incidence was greater in group 2 (30 vs 4, P < .001). Combined HF or all-cause mortality was greater in group 2 (46 vs 14, P < .001). Multivariate analysis revealed that HF was associated with E/e′ ratio (P < .0001), systolic blood pressure (P = .0123), and LV mass index (P = .042). Combined HF or all-cause mortality was associated with E/e′ ratio (P < .0001), LV mass index (P = .009), and lower calcium channel blocker use (P = .0011). Conclusions HF alone or HF and all-cause mortality were increased in patients with grade 1 DD in the presence of LV hypertrophy or elevated LV filling pressures.
