Prediction of Heart Failure — An Art Aided by Technology

Abstract
Heart failure is common, has a poor prognosis,1 and can be treated.2 The incidence is increasing, partly because of improved survival after myocardial infarction and partly because the population is aging and heart failure is a disease of the elderly. The most common causes are coronary heart disease and hypertension, and the prevention of heart failure is inextricably linked to the prevention of these disorders. An enlarged heart, a known precursor of heart failure, is often detectable before the onset of symptoms, and early treatment slows the progression to overt heart failure.3 Patients included in recent trials of new treatments . . .
