Aims
We performed a prospective multi-center study to assess gender-specific differences in the predictive value of the measured level of NT-proBNP and the calculated Heart Failure Survival Score (HFSS).
Methods
Baseline characteristics and follow-up data up to 5 years from 2,019 men and 530 women diagnosed with chronic heart failure (CHF) due to ischemic heart disease or dilated cardiomyopathy were prospectively compared. Death from any cause constituted the endpoint of the study. NT-proBNP was measured and HFSS calculated according to standard methods. Survival of men and women according to level of NT-proBNP and HFSS was analyzed in logistic regression models.
Results
Median NT-proBNP level in men was 1,394 ng/l (IQR 516–3,406 ng/l) and 1,168 ng/l (IQR 444–2,830 ng/l) in women (
p
 = n.s.). Median HFSS value was 8.4 (IQR 7.7–9.1) and 8.5 (8.0–9.1) in men and women, respectively. NT-proBNP levels and HFSS score correlated well with survival rates in both genders (
p
for interaction = 0.22 for NT-proBNP and 0.93 for HFSS). The all-cause death rates were similar in men and women.
Conclusion
Despite a number of gender-specific differences in CHF and the general predominance of men measured levels of NT-proBNP and HFSS score can be utilized for risk stratification with similar informative value in men and women.
