Diastolic heart failure. Constrictive, restrictive, and pericardial
1Cardiology Unit, Fletcher Allen Health Care, University of Vermont, Burlington, USA.
Insights
Diastolic dysfunction, a cause of heart failure with normal systolic function, stems from myocardial or pericardial issues. Distinguishing between restrictive and constrictive heart conditions requires careful hemodynamic and echocardiographic analysis.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Heart failure with normal systolic function often indicates diastolic dysfunction.
- Diastolic dysfunction arises from myocardial or pericardial disorders.
- Amyloidosis exemplifies restrictive cardiomyopathy causing diastolic dysfunction.
Purpose of the Study:
- To highlight the challenges in differentiating restrictive and constrictive cardiac pathologies.
- To emphasize the importance of hemodynamic and Doppler echocardiographic features.
Main Methods:
- Review of clinical presentations of diastolic dysfunction.
- Analysis of hemodynamic and Doppler echocardiographic findings in restrictive and constrictive diseases.
Main Results:
- Myocardial disorders lead to restrictive physiology (e.g., amyloidosis).
- Pericardial disorders typically cause constrictive physiology.
- Distinguishing these conditions necessitates detailed hemodynamic and echocardiographic assessment.
Conclusions:
- Diastolic dysfunction in heart failure warrants investigation into underlying myocardial or pericardial causes.
- Accurate differentiation between restrictive and constrictive physiology is crucial for appropriate management.
- Hemodynamic and Doppler echocardiography are key diagnostic tools.
Abstract:
Clinical heart failure with normal systolic function is suggestive of diastolic dysfunction. This can result from myocardial or pericardial disorders. Myocardial disorders are a broad range of pathologies leading to restrictive physiology. Amyloidosis is a prototype of restrictive cardiomyopathy leading to diastolic dysfunction. Pericardial disorders leading to diastolic heart failure are usually in the form of constrictive physiology. Differentiation between restrictive and constrictive pathologies is often difficult and require careful attention to hemodynamic and Doppler echocardiographic features.
