A single-center retrospective study of Vitamin D status and acute left ventricular heart failure from a super specialty tertiary care hospital in Northeast India

Abstract

Introduction: Heart failure (HF) is a progressive clinical condition and is a major cause of mortality and morbidity. Various studies have shown the association of Vitamin D deficiency with HF. The present study aimed to investigate the Vitamin D status among acute left ventricular failure (LVF) patients admitted to our hospital. Materials and Methods: Medical records of 55 acute LVF patients were retrospectively assessed. Patients were categorized according to their Vitamin D status. Demographics, risk factors, clinical presentations, and biochemical data of the patients were analyzed and documented. Results: Patients were grouped based on their Vitamin D status as deficient (40%; n = 22), insufficient (32.7%; n = 18), optimal (23.6%; n = 13), and toxic (3.6%; n = 2). The overall cohort included 67.3% (n = 37) of males with a male/female ratio of 2.1:1. Ages ranged from 22 to 86 years with a mean age of 64.8 years ± 2.3. Rural/Urban was 1:0.9. Hypertension (63.6%; n = 35) was the predominant risk factor across all groups. Mortality was the highest in the Vitamin D deficient group (36.4%; n = 8). The most common symptom observed was dyspnea (76.4%; n = 42). A high incidence of HF with reduced ejection fraction (58.1%; n = 32) was seen in the entire cohort with the highest prevalence in the Vitamin D-deficient group (27.3%; n = 15). Conclusions: Our study revealed a high occurrence of Vitamin D deficiency and insufficiency among HF patients. Routine screening of Vitamin D levels should be done in patients with unexplained cardiac problems. Serious adverse events, including HF, can be prevented and/or reduced on early diagnosis and treatment of Vitamin D deficiency/insufficiency.
