Popis: Background and Aim: This study explored the correlation between vitamin D status and the severity of coronary artery disease (CAD), as well as left ventricular function in patients with acute coronary syndrome (ACS). Materials and Methods: This prospective observational study included 102 patients diagnosed with ACS admitted to an Indian tertiary care facility from January 2021 to December 2021. Upon admission, the researchers collected baseline data of the patients and measured serum vitamin D levels. CAD severity was evaluated using Gensini and SYNTAX scores, and left ventricular ejection fraction (LVEF) was measured using echocardiography. Results: The study cohort had a median age of 56.5 years, with males comprising 62.7% of the total patient population. Anterior wall myocardial infarction was the most common presentation (59.8%), and 32.4% of patients had double vessel disease (DVD). The median vitamin D level was 18.3 ng/mL (interquartile range 12.7-26.8). Patients with vitamin D deficiency (≤20 ng/mL) exhibited significantly higher Gensini (46.5-94) and SYNTAX (7.5-38) scores than those with optimal levels (>30 ng/mL) (P < 0.001). A notable inverse correlation was found between vitamin D levels and both Gensini (r=-0.572, P < 0.001) and SYNTAX (r=-0.787, P < 0.001) scores. Reduced vitamin D levels were linked to decreased LVEF (P = 0.018) and a higher incidence of multivessel disease, particularly DVD (P = 0.009). Conclusion: This study revealed a significant negative correlation between low vitamin D status, CAD severity, and left ventricular dysfunction in patients with ACS. These results suggest that low vitamin D status indicates vitamin D deficiency and plays a crucial role in the occurrence and progression of coronary atherosclerosis.
