Pump failure death and sudden cardiac death in patients with cardiac dysfunction: a search for prognostic predictive factors--a long-term follow-up study.
BACKGROUND
There have been few reports that have analyzed the predictive factors for heart failure death, which is sub-divided into pump failure death and sudden cardiac death, in the long term.


RESULTS
We followed 186 consecutive patients with myocardial infarction (MI) and 115 consecutive patients with non-ischemic heart failure (NIHF) during 73+/-3 months. In the MI group, 26 died from pump failure and 12 died from sudden cardiac death. In the NIHF group, 21 died from pump failure and 9 died from sudden cardiac death. Multivariate analysis revealed that the log B-type natriuretic peptide (BNP) was an independent predictor for pump failure death in both groups. In the MI group, the estimated glomerular filtration rate (eGFR) was an independent predictor for sudden cardiac death. Kaplan-Meier analysis revealed that a high BNP level was a risk factor for pump failure death in either MI or NIHF patients. On the other hand, the sudden cardiac death rate was significantly higher in the MI patients with low eGFR than in those with high eGFR.


CONCLUSIONS
The plasma BNP level is an independent predictor for pump failure death in both MI and NIHF patients. The eGFR is an independent predictor for sudden cardiac death in MI patients.
