Summary

The present study is testing in a combined design to types of drugs in patients with chronic heart failure: 1) Hydralazine in combination with isosorbide dinitrate (BiDil) and 2) Metformin hydrochloride. The study is double blind, placebo controlled.

1. The first hypothesis is that hydralazine in combination with isosorbide dinitrate can reduce mortality and hospitalization with worsening heart failure in chronic heart failure patients with reduced LVEF.
2. The second hypothesis is that treatment with metformin in chronic heart failure patients with reduced LVEF and type 2 diabetes / diabetes risk / insulin resistance can reduce mortality and cardiovascular hospitalizations. Among secondary endpoints are reduction in new-onset diabetes in heart failure patients with insulin resistance and diabetes risk profile and patient safety.
