Left ventricular diastolic dysfunction in chronic kidney disease and anaesthesia implications

Area of Science:

• Cardiology
• Nephrology

Background:

• Left ventricular diastolic dysfunction is prevalent in patients with chronic kidney disease (CKD).
• Diastolic dysfunction involves abnormal ventricular relaxation, distensibility, or filling, potentially with normal or reduced ejection fraction.
• Heart failure with preserved ejection fraction (HFpEF) is frequently linked to diastolic dysfunction.

Purpose of the Study:

• To highlight the association between CKD and left ventricular diastolic dysfunction.
• To emphasize the diagnostic role of echocardiography in assessing diastolic dysfunction.
• To underscore the clinical implications of severe diastolic dysfunction, particularly in surgical patients.

Main Methods:

• Echocardiography is the primary imaging modality used.
• Assessment of left ventricular diastolic function parameters.
• Review of clinical outcomes in patients with varying grades of diastolic dysfunction.

Main Results:

• Left ventricular diastolic dysfunction is a frequent comorbidity in CKD.
• Severe diastolic dysfunction (Grade III) is associated with increased major adverse cardiovascular events.
• Peri-operative complications like pulmonary edema are noted in patients with significant diastolic dysfunction.

Conclusions:

• Left ventricular diastolic dysfunction is a significant concern in CKD patients.
• Echocardiographic evaluation is crucial for identifying and grading diastolic dysfunction.
• Management strategies should address diastolic dysfunction to mitigate cardiovascular risks, especially peri-operatively.
