Vit D levels in the different study groups, expressed as ng/ml. *Significant differences were found between PH and LVF groups (p = 0.017) and between PH group and HS (p = 0.001). Difference between LVF and HS groups was not significant (p = 0.046). HS, healthy subjects; LVF, left ventricular failure; PH, pulmonary hypertension; Vit D, vitamin D
