Introduction: Aims: hypovitaminosis D has frequently been identified in patients with heart failure (HF). However, few studies have been conducted in regions with high solar incidence. Therefore, this study aimed to evaluate vitamin D status and predictors of 25-hydroxyvitamin D (25(OH)D) levels in patients with HF living in a sunny region (5 °- 6 °S). Methods: this cross-sectional study enrolled 70 patients with HF. Biodemographic, clinical, biochemical, dietary, and sun exposure data were collected, and 25(OH)D levels were measured. Results: the mean 25(OH)D level was 40.1 (12.4) ng/mL, and 24.3 % (95 % CI: 14.2-33.8) of patients with HF had hypovitaminosis D (25(OH)D < 30 ng/mL). Female patients (p = 0.001), those with ischemic etiology (p = 0.03) and those with high parathyroid hormone levels (> 67 pg/mL) (p = 0.034) were more likely to present hypovitaminosis D. Higher 25(OH)D levels were observed in men than in women (β = 7.78, p = 0.005) and in patients with HF in New York Heart Association (NHYA) functional class I when compared to those in class III/IV (β = 8.23, p = 0.032). Conclusions: the majority of patients with HF had sufficient 25(OH)D levels. Sex and functional classification were identified as independent predictors of 25(OH)D levels. These results highlight the need for increased monitoring of vitamin D status among female patients with heart failure and those with more severe symptoms. |
