Insights
Diastolic heart failure, characterized by preserved systolic function, is increasingly recognized, especially in older adults. Current treatments remain empirical due to limited evidence-based data.
Area of Science:
- Cardiology
- Internal Medicine
Context:
- Historically, heart failure was solely linked to systolic dysfunction.
- Recent observations define heart failure with preserved systolic function (diastolic heart failure).
- This condition is increasingly recognized in elderly populations.
Purpose:
- To define diastolic heart failure and its associated conditions.
- To highlight the prevalence and contributing factors of diastolic heart failure.
- To address the current limitations in evidence-based treatment strategies.
Summary:
- Diastolic heart failure, or heart failure with preserved systolic function, is a clinical syndrome not primarily caused by reduced contractility.
- It is frequently associated with conditions such as hypertension, aortic stenosis, hypertrophic cardiomyopathy, and pericardial diseases.
- This syndrome is more prevalent in the elderly population.
Impact:
- Recognizes diastolic heart failure as a distinct clinical entity.
- Identifies key conditions contributing to diastolic heart failure.
- Emphasizes the need for further research into effective, evidence-based treatments for diastolic heart failure.
Abstract:
Until recently, the development of heart failure was related exclusively to the acute or chronic impairment in systolic function. Currently, the concept of heart failure not sustained primarily by a significant reduction in contractility has been clearly defined by several epidemiological and pathophysiological observations. This condition, defined as 'diastolic heart failure' or 'heart failure with preserved systolic function' can be related to different cardiac diseases with a higher prevalence in the elderly. Afterload mismatch situations, such as hypertension or aortic stenosis, as well as hypertrophic cardiomyopathy or pericardial diseases, determine this common clinical syndrome more frequently. Currently, the treatment of diastolic heart failure is still empirical, as there are few and inconclusive data coming from evidence-based medicine.
