Evaluation of the relationship between vitamin D deficiency and right
and left ventricular systolic function in patients without coronary
artery disease
Abstract
Background: Vitamin D deficiency is one of the most common
nutritional deficiencies. Cardiovascular disease patients are also prone
to this condition. Recently, a relationship between vitamin D deficiency
and cardiovascular diseases has been suggested. This study aims to
compare the relationship between ventricular systolic function and
vitamin D deficiency. Methods: This study investigated patients
without obvious coronary artery disease between 2020 and 2021. First,
vitamin D levels were measured in the patients. Then, they were divided
into two groups based on a 30 ng/dl cut-off point. All patients
underwent echocardiography and ventricular systolic function parameters
were evaluated and compared. Results: In this study, 27
patients with normal vitamin D levels and 47 patients with vitamin D
deficiency entered the study. There was no significant difference in
demographic variables and underlying diseases between these two groups.
There was no significant difference between left ventricular (LV)
systolic function parameters including ejection fraction (EF), and LV
end-systolic/diastolic volume. No significant difference was also
observed between right ventricular (RV) systolic function parameters
including Tricuspid Annular Plane Systolic Excursion (TAPSE), RV
fractional area change (RVFAC), Right ventricular systolic velocity
(RVSM) in tissue Doppler echocardiography as well as RV diastolic
parameters such as A, E, E´, deceleration time (DT), right atrial volume
(RAVi) as a precursor of right ventricular systolic dysfunction groups.
Conclusion: Based on the results of this study, there is no
relationship between vitamin D levels and ventricular systolic
dysfunction.
