Brief Summary:
Previous studies have demonstrated a direct association between blood pressure level and cardiovascular risk. However in patients with heart failure this association is considered controversial. The aim of this study is to evaluate the effect of the reduction of blood pressure in patients with heart failure. The investigators will examine the effects of this intervention over mortality, quality of life, and cardiac function.

Arm Intervention/treatment
Experimental: Intervention Drug: Hydralazine/amlodipine
Patients will receive drug therapy aimed to reducing blood pressure - first line drug will be hydralazine up to 100mg/day; if systolic blood pressure reduces less than 20% from baseline and remains over 100mmHg patients will further receive amlodipine up to 10mg/day

Placebo Comparator: Control Drug: Placebo
Patients will receive placebo
