Key result
Vitamin D supplementation linked to an ~83% decrease in PVCs in a deficient patient.
Why the study?
Serum vitamin D levels are linked to physical fitness and cardiac rehabilitation response, and vitamin D is involved in cardiomyocyte function.
Does vitamin D supplementation combined with cardiac rehabilitation reduce PVC burden in patients with vitamin D deficiency and RVOT PVCs?
Case Report (n=1)
No
Does vitamin D supplementation combined with cardiac rehabilitation reduce PVC burden in patients with vitamin D deficiency and RVOT PVCs?
In a patient with RVOT PVCs and vitamin D deficiency, adding vitamin D supplementation to cardiac rehabilitation significantly reduced PVC burden and eliminated symptoms.
Introduction. Vitamin D deficiency is a quite common pathology in European countries. Serum vitamin D levels are closely linked to physical fitness and lesser response to cardiac rehabilitation in various categories of patients with heart disease. Vitamin D is also involved in the function of heart cells via a vitamin D receptors found in cardiomyocytes. We present the case of a patient with vitamin D deficiency and symptomatic premature ventricular contractions (PVCs), in whom cardiac rehabilitation decreased PVC number, but association with vitamin D supplements led to a significant decrease in PVCs and complete disappearance of symptoms.

Cismaru et al. (2020) conducted a case report in Premature ventricular contractions (PVCs) and Vitamin D deficiency (n=1). Vitamin D supplementation and cardiac rehabilitation vs. Baseline (no treatment) and cardiac rehabilitation alone was evaluated on Number of premature ventricular contractions (PVCs) per 24 hours. In a patient with vitamin D deficiency, adding vitamin D supplementation to cardiac rehabilitation decreased premature ventricular contractions from 1350 to 230 per 24 hours and eliminated symptoms.
