Left Ventricular Diastolic Dysfunction in Cardiac Surgery: A Narrative Review.

Area of Science:

• Cardiology
• Cardiac Surgery
• Anesthesiology

Background:

• Diastolic dysfunction (DD) is a complex cardiac condition affecting left ventricular filling and stroke volume.
• Perioperative ischemia-reperfusion injury and pre-existing DD significantly impact surgical outcomes, including complications and hospital stay.
• Risk factors for DD include age, hypertension, diabetes, and left ventricular hypertrophy, complicating perioperative management.

Purpose of the Study:

• To review and consolidate current knowledge on diastolic dysfunction in cardiac surgery.
• To provide clinically applicable information for diagnosing and managing perioperative DD.
• To highlight the need for validated diagnostic criteria and individualized treatment strategies.

Main Methods:

• Literature review of studies on cardiac diastolic dysfunction.
• Analysis of factors contributing to perioperative DD.
• Synthesis of information on diagnostic challenges and therapeutic approaches.

Main Results:

• Diastolic dysfunction is linked to adverse postoperative outcomes and prolonged hospital stays.
• Current diagnostic guidelines for DD lack perioperative validation.
• Effective management requires individualized strategies for fluid management, rate control, and lusitropic medications.

Conclusions:

• Timely diagnosis of perioperative DD is crucial for preventing low cardiac output syndrome.
• An individualized approach to treatment, considering specific patient factors, is necessary.
• Further research is needed to validate diagnostic criteria for DD in the perioperative setting.
