Abstract

Many patients with essential hypertension (EH) exhibit increased left ventricular mass. Similarly, elevated circulating levels of an endogenous ouabainlike factor (OLF) have been described in some but not all patients with EH. Moreover, ouabain has a hypertrophic influence on isolated cardiac myocytes. Accordingly, we investigated relationships among plasma OLF, left ventricular mass, and cardiac function in patients with EH. Plasma OLF was determined in 110 normotensive subjects and 128 patients with EH. Echocardiographic parameters and humoral determinants were measured in EH. Plasma OLF levels were increased (P2, P=0.0003, and 57.10±1.48 versus 52.30±1.14 mL/m2, P=0.02, respectively), although heart rate was slower (74.2±1.3 versus 80.5±1.3 bpm, P=0.005). Multiple regression analysis that tested the influence of body mass index, age, gender, 24-hour blood pressure, and OLF on left ventricular mass revealed independent contributions of systolic (13.2%) and diastolic (12.4%) blood pressure and plasma OLF (11.6%) to left ventricular mass. We conclude that ≃50% of patients with uncomplicated EH have elevated-high circulating OLF levels, higher diastolic blood pressure, greater left ventricular mass and stroke volume, and reduced heart rate. We propose that the OLF affects cardiovascular function and structure and should be considered as a factor that contributes to the risk of morbid events.
