Background: Previous studies have reported endothelial dysfunction and inflammatory cytokine in heart failure patients (HF).

Objectives: The purpose of this study was to determine the effects of creatine monohydrate and exercise on inflammatory and endothelial dysfunction markers among HF patients.

Patients and Methods: One hundred patients were prospectively randomized into two groups: Intervention group which received 5 grams/day creatine monohydrate and exercised for 8 weeks; and control group which did not receive any interventions. Interleukine-6 (IL-6), high sensitivity C reactive protein (hs-CRP), P-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule 1 (VCAM-1) were measured at the start and end of the study for both groups.

Results: In total, 100 patients including 50 controls and 50 intervention group (54% male, mean EF of 34.2 ± ۱۰٫۵% and 52% male, mean EF of 35.6 ± ۱۲٫۷%, respectively) were analyzed. The serum levels of hs-CRP and IL-6 increased at the end of the study in the control group compared to the baseline, (7.5 ± ۱٫۵ mg/L vs. 6.9 ± ۱٫۳ mg/L, P < 0.05 and 3.0 ± ۰٫۷۵ ng/L vs. 2.55 ± ۰٫۹ ng/L, P < 0.05, respectively). However, compared to the baseline, the level of both markers decreased at the end of the study in the intervention group (6.3 ± ۱٫۶ mg/L vs.7.5 ± ۱٫۵ mg/L, P < 0.05 and 2.1 ± ۰٫۸ ng/L vs.2.5 ± ۰٫۵ ng/L, P < 0.05). Also, P-selectin and ICAM-1 levels increased at the end of study (56.9 ± ۱٫۸ ng/L vs. 51.9 ± ۱٫۵ ng/L, P < 0.05 and 368.1 ± ۲۵٫۴ µg/L vs. 353.1 ± ۱۰٫۴ µg/L, P < 0.05 respectively). Inversely, the levels of these markers decreased in the intervention group, at the end of study (49.7 ± ۱٫۹ ng/l vs. 51.4 ± ۲٫۱ ng/l, P < 0.05 and 342.7 ± ۱۶٫۵ µg/l vs. 350.4 ± ۱۴٫۷ µg/l, P < 0.05, respectively). VCAM-1 level was not decreased significantly at the end of the study in the intervention group (570.5 ± ۷۸٫۴ µg/L vs. 575.3 ± ۸۶٫۵ µg/L, P > 0.05).

Conclusions: Combination of creatine monohydrate and exercise attenuated inflammation and endothelial dysfunction markers among heart failure patients.
