[Prevention of heart failure].
Heart failure is a major problem of public health, associated with poor outcome in the advanced stage, thus justifying its prevention. Primary prevention is based on the prevention and treatment of its principal etiologic factors, hypertension and coronary artery disease. Broad use of echocardiography or dosage of neurohormonal markers improve detection of asymptomatic left ventricular dysfunction. In ischemic heart disease, coronary recanalisation prevents or limits left ventricular remodeling and dysfunction, even if the "open artery" theory has not been entirely proved. Understanding the deleterous role of neurohormonal stimulation results in a large use of ACE-inhibitors, which beneficial effect has been demonstrated also in case of asymptomatic left ventricular dysfunction. Betablockers, already largely used after myocardial infarction, seem to have also a beneficial effect in heart failure: the same is probably also true for angiotensin II-antagonists. Double blocking of both the sympathetic nervous system and the angiotensin-aldosterone system seems to be recommended. More precisely understanding the pathways signaling the processes of ventricular remodeling and dysfunction points to new potential targets for a preventive treatment: endothelin receptors, apoptosis, oxidative stress, cytokines or even angiogenesis.
