B Vitamins as Adjunctive Treatment for Chronic Heart Failure.

INTRODUCTION

Vitamin B deficiency causes cardiac hypertrophy, reduced cardiac contractility, and arrhythmias.The purpose of this study is to perform a network meta-analysis of randomized controlled trials of vitamin B supplements in a group of 150 patients who meet the eligibility criteria.The study also aims to describe the effect of synthetic multivitamins (pyridoxine, folic acid, and cyanocobalamin) on the laboratory findings reflecting the severity of chronic heart failure (cholesterol, glucose, and fibrinogen).

METHODS

The experiment involved a group of people (150 individuals) diagnosed with chronic heart failure with reduced left ventricular ejection fraction. The study compared serum levels of B vitamins measured after the therapy and at baseline. The second part of the study focused on the assessment of the laboratory findings reflecting the severity of cardiovascular pathology and indicating an increased risk of vascular catastrophes.

RESULTS

Clinical trials among patients diagnosed with chronic heart failure showed that the intake of synthetic forms of pyridoxine, folic acid, and cyanocobalamin slightly increases systolic, diastolic and central venous pressure while decreasing the heart rate and increasing LVEF. Thiamine acts as a vasodilator. It reduces the cardiac afterload and improves heart function.

CONCLUSION

The results obtained can be useful in terms of improving the comprehensive treatment strategy for chronic heart failure and further investigation of the effects produced by the intake of B vitamins.
