title: Progression from hypertension to heart failure. Mechanisms and management.
abstract: Patients with hypertension are at increased risk of developing heart failure (HF), but the mechanisms by which hypertension leads to HF have not been clarified [although left ventricular hypertrophy (LVH) is clearly a predictor of an increased risk of HF]. Similarly, although antihypertensive therapy has been shown to reduce the risk of HF in hypertensive patients, it is not known how this benefit is produced and, currently, there is no clear evidence that any class of antihypertensive agent is more effective than any other in this respect. On theoretical grounds, beta-blockers would be expected to be ideal agents for the prevention of HF in hypertensive patients. In addition to control of blood pressure and regression of LVH, they have clear benefits on morbidity and mortality after myocardial infarction (MI), which probably plays a major role in the development of HF in hypertensive patients, and on the prognosis of HF itself. A reduction in long-term mortality after MI has been demonstrated only for non-selective beta-blockers. Carvedilol, a non-selective beta-blocker which also has other ancillary properties including alpha-1-receptor blockade and antioxidant effects and a favourable metabolic profile, may be an appropriate choice for the prevention of HF in hypertensive patients. This is reinforced by the salutary benefits of carvedilol for the reduction in the morbidity and mortality of HF itself.
