association between left ventricle ejection fraction and vitamin d levels in congestive heart failure: a cross sectional study

Background: congestive heart failure (chf) is a chronic disease that incidence is growing in the population. vitamin d effects on directly myocardial cells. the aim of this study was to investigate the association between vitamin d levels with ejection fraction of left ventricle. methods: the study population consisted of 101 patients admitted with heart failure. age, gender, and demographic characteristics (diabetes mellitus, hypertension, smoking-nonsmoking, coronary artery disease) of all patients were recorded. in all patients for blood analyses vitamin d, creatine, crp and lipid profile were studied. and all patients were studied echocardiography. results: chf patients, in our population 35 (34.7%) patient is female and 66 (65.3%) patient is male. the mean age of our patients was calculated as 67.4±12.9 years. our patients laboratory parameters mean were measured for vitamin d 24.3±17.3 ng/ml. left ventricular ejection fraction (lvef) mean was measured 31.8±9.5. in our study group lvef and vitamin d was correlated with each other. conclusion: vitamin d and lvef had a positive correlation in heart failure patients. it may be occured with the protective effect of vitamin d or consequence of hipovitaminosis.
