Insights
Treatment for heart failure has evolved, with increased use of recommended therapies like beta-blockers, angiotensin receptor blockers (ARBs), and aldosterone blockers. However, combined therapies remain underutilized despite guidelines.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Heart failure treatment has significantly advanced due to clinical trials.
- Neurohormonal system antagonism is key for improving heart failure prognosis.
- Angiotensin-converting enzyme (ACE)-inhibitors, beta-blockers, angiotensin receptor blockers (ARBs), and aldosterone blockers are proven effective.
Purpose of the Study:
- To examine trends in pharmacological treatment for heart failure.
- To assess the adoption of evidence-based therapies from 1995 to 2005 using the IN-CHF registry.
- To evaluate the clinical practice translation of new heart failure guidelines.
Main Methods:
- Analysis of data from the IN-CHF registry (1995-2005).
- Examination of changes in the utilization of specific drug classes.
- Comparison of treatment patterns before and after key guideline publications (CHARM, Val-HeFT).
Main Results:
- Significant increase in the use of beta-blockers, ARBs, and aldosterone antagonists.
- Beta-blocker use rose notably in elderly and advanced NYHA class patients.
- Combined ACE-inhibitor and ARB use, and triple therapy (beta-blocker, ACE-inhibitor, ARB), remained low (1.1% and 0.8% respectively).
- Statin use increased from 5% to 20% in this population.
Conclusions:
- While evidence-based therapies for heart failure are increasingly used, combined regimen adoption lags behind recommendations.
- Further efforts are needed to align clinical practice with guideline recommendations for optimal heart failure management.
- The role of statins in heart failure requires further investigation.
Abstract:
In the last years the treatment of heart failure has radically changed due to the results of multicenter clinical trials. The antagonism of neurohormonal systems has proved to be the only strategy, which favorably modifies the prognosis of the patients with heart failure. Particularly, the effectiveness of angiotensin-converting enzyme (ACE)-inhibitors and beta-blockers has been proven in patients with heart failure and left ventricular dysfunction; more recently, angiotensin receptor blockers (ARBs) and aldosterone blockers have shown to improve the outcome in heart failure. The public health im portance of translating this body of evidence of research into clinical practice is paramount. We used data from the IN-CHF registry to examine changes in the use of pharmacological treatment from 1995 to 2005. The proportion of patients receiving an ACE-inhibitor was slightly higher in the 1995-2000 than after but this difference is not statistically significant. The use of "recommended therapies" as beta-blockers, aldosterone antagonists and ARBs increased significantly in these 10 years. The use of beta-blockers also increased significantly among elderly patients and patients in advanced NYHA class. Patients treated with the combination of ACE-inhibitors and ARBs are very few (1.1%), even if this association is now recommended by the European Society of Cardiology guidelines. The same analysis repeated after the CHARM and Val-HeFT publication shows that this association is used in 2.0% of the patients. The proportion of patients treated with a beta-blocker plus ACE-inhibitors plus ARB is only 0.8%. Use of digitalis and calcium channel blockers fell continuously from 1995 whereas use of diuretics and anticoagulants remained relatively constant. Statins are becoming widely used in this population (from 5 to 20%) even if the information on the effect of these drugs in heart failure is still incomplete.
