[Doppler echocardiographic assessment of diastolic function of left ventricle]

Area of Science:

• Cardiology
• Cardiovascular Physiology

Background:

• Diastolic dysfunction is prevalent in congestive heart failure (CHF), often occurring without reduced ejection fraction (LVEF>50%).
• It involves impaired left ventricular relaxation or compliance, affecting diastolic filling.
• Conditions like hypertension and coronary artery disease frequently cause diastolic dysfunction.

Purpose of the Study:

• To review the clinical impact of echocardiographic methods in assessing diastolic dysfunction.
• To highlight the importance of understanding diastolic impairment in CHF.

Main Methods:

• Review of classic and recent echocardiographic contributions to diastology.
• Focus on noninvasive Doppler-echocardiographic assessment techniques.

Main Results:

• Diastolic dysfunction is common, even with preserved ejection fraction.
• Elevated left atrial pressures compensate for impaired filling.
• The severity of diastolic dysfunction correlates with symptom severity in CHF patients with reduced systolic function.

Conclusions:

• Accurate echocardiographic assessment of diastolic function is crucial for understanding and managing this condition.
• Diastolic dysfunction plays a significant role in the pathophysiology and symptomatology of CHF.
