[Treatment of chronic heart failure: current views].

New agents for treating chronic heart failure include angiotensin converting enzyme (ACE) inhibitors, betablockers and phosphodiesterase inhibitors. The ACE inhibitors represent the major therapeutic advance of the 1980-1990 decade. This is the most effective class of drugs on survival, whatever the stage of heart failure and it shows the evolution towards symptoms in asymptomatic patients. Studies currently under way are evaluating the dose-effect relationship of ACE inhibitors. Betablockers improve the quality of life and physical performance but a benefit on mortality has not been shown in two recent trials. Phosphodiesterase inhibitors improve quality of life and physical performance at the price of an increase in mortality. Therefore, they are not indicated in the treatment of heart failure. However, new molecules such as vesnarininone or pimobendan are under trial. Finally, in the next few years, the introduction of antagonists to Angiotensin II receptors is eagerly awaited.
