[The diastolic function: an echocardiographic study and its clinical meaning]

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Heart failure with preserved ejection fraction (HFpEF) presents with symptoms despite normal systolic function.
• Diastolic dysfunction is the primary cause of HFpEF symptoms.
• Echocardiography is crucial for non-invasive assessment of diastolic anomalies.

Purpose of the Study:

• To highlight the importance of diastolic function assessment in HFpEF.
• To review various echocardiographic methods for evaluating diastolic function.
• To emphasize the role of integrated analysis in improving diagnostic accuracy.

Main Methods:

• Pulsed Doppler analysis of transmitral flow.
• Assessment of pulmonary venous flow.
• Color M-Mode evaluation of mitral flow propagation velocity.
• Doppler tissue imaging for myocardial diastolic velocities.
• Integration of preload variations.

Main Results:

• Transmitral flow analysis is a primary method for diastolic function evaluation.
• Additional techniques like pulmonary venous flow and tissue Doppler imaging provide complementary data.
• Integrated analysis of multiple echocardiographic parameters enhances diagnostic accuracy.

Conclusions:

• Comprehensive echocardiographic assessment, integrating various Doppler techniques, is essential for diagnosing diastolic dysfunction in HFpEF.
• Accurate evaluation of diastolic function and filling pressures aids in risk stratification for short/medium-term events.
• Advanced echocardiographic methods improve the characterization of diastolic function in patients with HFpEF.
