Abstract
INTRODUCTION: Trimetazidine has been reported to have potential benefits in patients with chronic heart failure (CHF). Soluble suppression of tumorigenicity-2 (sST2) was shown to worsen CHF and, hence, has a diagnostic value in heart failure. The aim of the present study was to evaluate the effectiveness of trimetazidine in patients expressing high and low levels of sST2 compared with their matched placebo. METHODS: In this prospective cohort study, 170 patients were enrolled. Patients expressing more than 35 ng/mL sST2 (S+) were split into a trimetazidine group (group A) and placebo group (group B). Likewise, patients expressing 35 ng/mL or less of sST2 (S-) were divided into a trimetazidine (group C) and placebo group (group D). Patients in both the trimetazidine groups were administered 20-mg twice-a-day doses of trimetazidine. Trimetazidine effectiveness was determined in terms of changes in cardiac function, motor function, and mental status at 1, 3, 6, and 12 months from baseline among the four groups. RESULTS: A total of 158 patients were included for final data analysis (group A, n = 50; group B, n = 57; group C, n = 27; group D, n = 24). On comparing different outcomes between the four groups and across the time points, significant difference was observed between the groups in ejection fraction (EF; P < 0.001), cardiac index (CI; P < 0.001), New York Heart Association score (P < 0.001), 6-min walk test (P < 0.001), Veterans Specific Activity Questionnaire (VSAQ; P < 0.001), Minnesota Living with Heart Failure Questionnaire (MLHFQ; P < 0.001), hospital anxiety and depression scores (P < 0.001), and Copenhagen Burnout Inventory (P < 0.001). Significant difference in systolic blood pressure (P < 0.001), heart rate (P < 0.001), EF (P < 0.001), CI (P < 0.001), VSAQ (P = 0.017), and MLHFQ (P < 0.001) was observed. CONCLUSION: Trimetazidine demonstrated an overall improvement in cardiac function, motor function, quality of life (QoL), and mental status in both S+ and S- patients. Among patients administered trimetazidine, significant changes in maximum outcomes were observed among those expressing higher levels of sST2 compared with placebo.
