Vitamin D Deficiency Predicts Poor Clinical Outcomes in Heart Failure Patients Undergoing Cardiac Resynchronization Therapy

Figure 2

Plasma NT-proBNP levels at baseline and after six months of CRT. We compared the baseline and six-month plasma NT-proBNP levels in patients groups of baseline plasma vitamin D levels below and above 24.13 ng/mL using the Mann-Whitney test. CRT: cardiac resynchronization therapy; NT-proBNP: N-terminal of the prohormone brain natriuretic peptide.
