- Abstract
- Left ventricular filling pressure (LVFP) is a marker for diastolic dysfunction and heart failure (HF) with preserved ejection fraction (pEF). The interaction between arterial stiffness (AS) and elevated LVFP has not been sufficiently investigated. In 257 patients with preserved left ventricular ejection fraction (mean age: 66 years, 53% female, mean left ventricular ejection fraction: 61%) and at least one cardiovascular risk factor (eg, hypertension and diabetes) for the development of HF or a previous diagnosis of HF, LVFP was estimated in accordance with the recommendations of the American Society of Echocardiography (elevated when E/e' ≥ 13, left atrial volume index ≥ 34 mL/m2). LVFP was correlated with radial pulse wave analysis (augmentation index normalized by 75 b/min [AIx@75]) and carotid-femoral pulse wave velocity (cfPWV). Thirty-eight percent of patients demonstrated an elevated LVFP. These patients were significantly older (68.3 ± 7.4 vs. 63.5 ± 7.6 years, P < .001), demonstrated a higher body mass index (29.8 ± 4.6 vs. 28.0 ± 5.0; P < .01), presented more often with hypertension (89.7% vs. 73.1%, P < .01), hypercholesterolemia (32.0% vs. 21.3%, P < .05), dyspnea on exertion (28.4% vs. 16.6%, P < .05), and peripheral edema (25.3% vs. 10.2%, P < .01). cfPWV and AIx@75 and were significantly elevated in patients with elevated LVFP (12.2 ± 2.7 m/s vs. 10.5 ± 2.6 m/s, P < .001, an 29.2 ± 6.7% vs. 27.4 ± 6.7%, P < .05 respectively). cfPWV and AIx@75 were correlated with echocardiographic parameters, that is, posterior wall thickness (r = 0.292, P < .001; r = 0.167, P < .01), left ventricular mass index (r = 0.255, P < .001; r = −0.192, P < .01), e' (r = −0.508, P < .001; r = −0.159, P < .05), and E/e' (r = 0.380, P < .001; r = 0.200, P < .01). cfPWV correlated with left atrial volume index (r = 0.189, P < .05) and increasing E/A ratio (r = −0.334, P < .001). Multivariate linear regression analysis demonstrated age and PWV as most important and independent predictors of LVFP elevation in the cohort. Increased AS measured by cfPWV was associated with an elevated LVFP in patients with preserved systolic function. Whether targeting AS as a major component of diastolic dysfunction and HF with preserved ejection fraction needs to be further investigated.
