EPIDEMIOLOGY AND HISTORY AHF/HF Disease Awareness

History of acute heart failure management Did you know? Despite having being used for decades, the effects of diuretics on mortality and morbidity have not been studied in patients with heart failure 7 1. Lechat et al.

Circulation 1956;13:664–74; 6. (Accessed 1 May 2013); 7. McMurray et al. Eur Heart J 2012;33:1787–847 Heart transplant image 1900–1970 Early models of heart failure focussed on hemodynamics, with edema as the key characteristic of the condition. This led to the widespread use of diuretics in patients with heart failure 1 The first half of the 20 th Century saw the introduction of mercurial diuretics for the treatment of congestive heart failure 2,3 The 1950’s saw the introduction of thiazide diuretics 3 and vasodilators such as hydralazine 5 The loop diuretic furosemide was approved by the Food and Drug Administration in 1966, 6 while in 1967, the first human-to-human heart transplant was performed. 3 Both of these are still used today in the management of heart failure 7 “... when heart failure occurs with normal rhythm, as in hypertension, mercurial diuretics usually prove more successful than digitalis in increasing the urinary output, in lessening pulmonary congestion, and in relieving dyspnoea” 4

History of acute heart failure management *A population-based study assessed survival rates for patients hospitalized for heart failure between 1987–2002 from four communities within the USA 1. McKee et al N Engl J Med 1971;285:1441–6; 2. (Accessed 1 May 2013); 3. McMurray et al. Eur Heart J 2012;33:1787–847; 4. Loehr et al. Am J Cardiol 2008;101:1016– –1990 The Framingham heart study was published in 1971 showing high mortality in patients with heart failure:1 “Despite modern management, congestive heart failure proved to be extremely lethal. The probability of dying within five years from onset of congestive heart failure was 62% for men and 42% for women” During the 1970’s and 1980’s, inotropes and intravenous nitrates were approved for patients with acute heart failure.2 These were the first advances in therapy in over a decade – there have been relatively few advances since Although nitrates are still used in the management of acute heart failure today, there is no robust evidence that they relieve dyspnoea or improve other clinical outcomes Intravenous drip Did you know? Acute heart failure is still associated with high levels of mortality; 30-day, 1-year and 5-year mortality rates for patients hospitalized for acute heart failure are approximately 10%, 22% and 42%, respectively*4

N Engl J Med 1974;290:499– –Present day Launch of two new agents for acute heart failure, but they are not approved by regulatory authorities in all markets: B-type natriuretic peptide (nesiritide; 2001; US only 1 ); calcium sensitizer (levosimendan; 2000; Scandinavia, Russia, Latin America 2 ) A number of novel therapies fail to demonstrate outcome benefits in clinical trials in patients with acute heart failure: 3–6 Clinical trials with a vasopressin V2 receptor blocker, an endothelin receptor antagonist and an adenosine receptor fail to demonstrate improvements in long-term ouctomes 3–5 2011: Several years after launch, a pivotal study shows artificial B-type natriuretic peptide has no effect on outcomes in patients with acute heart failure 6 Hope on the horizon? The need to raise awareness of acute heart failure and improve patient care pathways is being increasingly recognized and many medical associations and have initiatives to address this. 7–9 Meanwhile, a number of potential novel therapies for acute heart failure are currently in clinical development 10 Did you know? The main therapies for acute heart failure recommended by the guidelines (loop diuretics, vasodilators and inotropes) are the same therapies that have been used for decades 11,12 There remains a significant need for improved disease management and new treatment options that reduce mortality in patients with acute heart failure
