Abstract:
BACKGROUND:Galectin-3 has emerged as a potential useful novel biomarker for heart failure and cardiovascular disease (CVD). However, it remains unclear whether galectin-3 is associated with recurrent cardiovascular events during long-term follow-up of patients with stable coronary heart disease (CHD) after adjustment for multiple established and novel risk factors. METHODS:We measured galectin-3 at baseline in a cohort consisting of 1035 CHD patients and followed them for 13 years to assess a combined CVD end point. Moreover, we adjusted for multiple traditional and novel risk factors. RESULTS:Galectin-3 concentration was positively associated with the number of affected coronary arteries, history of heart failure, and multiple traditional risk factors. Also, galectin-3 correlated significantly with emerging risk factors [e.g., cystatin C, N-terminal pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity (hs)-troponin]. During follow-up (median 12.0 years), 260 fatal and nonfatal CVD events occurred. The top quartile of galectin-3 concentration was significantly associated with CVD events compared to the bottom quartile after adjustment for age and sex [hazard ratio (HR) 1.88 (95% CI, 1.30-2.73), P = 0.001 for trend] as well as for established CVD risk factors (HR 1.67, 95% CI, 1.14-2.46, P = 0.011 for trend). However, after adjustment for other biomarkers available [including eGFR (estimated glomerular filtration rate), sST2 protein, GDF-15 (growth differentiation factor 15), NT-proBNP, and hs-troponin], the association was no longer statistically significant [HR 1.11 (95% CI 0.72-1.70), P = 0.82 for trend]. CONCLUSIONS:Galectin-3 does not independently predict recurrent cardiovascular events in patients with established CHD after adjustment for markers of hemodynamic stress, myocardial injury, inflammation, and renal dysfunction.
