Prognostic value of chromogranin A in chronic heart failure: data from the GISSI-Heart Failure trial.
OBJECTIVE
To assess the association between circulating levels of chromogranin A (CgA) and outcome in a large population of patients with chronic heart failure (HF).


RESULTS
Plasma CgA levels were measured at randomization and after 3 months in 1233 patients (median age 68 years, 80% male) with chronic, stable HF from the GISSI-HF trial. Circulating CgA levels were associated with several established risk markers in HF, including increased age, diabetes, reduced renal function, and heart rate variability. During a median follow-up of 3.9 years, 333 patients (27%) died. By univariable analysis, plasma CgA levels at baseline were strongly associated with all-cause mortality during follow-up; 2nd vs. 1st tertile: HR 1.58 (1.17-2.11), P = 0.002; and 3rd vs. 1st tertile: HR 2.35 (1.78-3.10), P < 0.0001. After adjustment for established risk factors of mortality, this association was attenuated and no longer significant. Randomized treatments with n-3 polyunsaturated fatty acid or rosuvastatin did not significantly change plasma CgA concentration over 3 months.


CONCLUSIONS
Measurement of circulating CgA levels in patients with chronic, stable HF does not provide incremental prognostic information to that obtained from physical examination, routine biochemical analysis, and contemporary HF biomarkers.
