Abstract

OBJECTIVE:

To assess the prognostic value of the mitogenic, antiapoptotic, angiogenic and antifibrotic hepatocyte growth factor (HGF) in heart failure (HF).

DESIGN:

Prospective cohort study.

SETTING/PATIENTS:

Assessment of HGF levels at inclusion in 351 patients with advanced HF (median 75 years, interquartile range (IQR) 63-82, 66% male).

MAIN OUTCOME MEASURES:

All-cause mortality, cardiovascular mortality.

RESULTS:

During a median follow-up of 16&emsp14;months, 26% of patients died. HGF tertiles were associated with an increasing risk for all-cause mortality (p < 0.001) with a hazard ratio (HR) of 3.06 (95% confidence interval (CI) 1.69 to 5.53) for the third compared with the first tertile. This association remained significant after multivariable adjustment for B-type natriuretic peptide (BNP) and other risk factors (p = 0.002). Subgroup analysis revealed that HGF was a strong predictor of the secondary end point cardiovascular mortality in ischaemic HF (p = 0.009) with an adjusted HR of 6.2 (95% CI 1.76 to 21.8) comparing the third with the first tertile but not in non-ischaemic HF (HR = 1.47, 95% CI 0.48 to 4.49, p = 0.5). Patients with high HGF but low BNP had a comparable survival rate to those with elevated BNP but low HGF (p=0.66). Of note, the dose of angiotensin converting enzyme (ACE) inhibitors inversely correlated with HGF concentrations (r = -0.25, p < 0.001).

CONCLUSIONS:

HGF is a strong and independent predictor of mortality in advanced HF and, in particular, in ischaemic HF. These results indicate that HGF with its multiple effects on myocardial function exerts an overall deleterious effect in advanced HF. HGF may be of special interest for risk prediction and tailoring of HF treatment.
