Heart failure with preserved LV function: pathophysiology, clinical presentation, treatment, and nursing implications

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Diastolic dysfunction causes heart failure in up to one-third of patients with dyspnea.
• Characterized by impaired left ventricular relaxation and filling during diastole.
• Often associated with left ventricular hypertrophy and ischemic conditions.

Purpose of the Study:

• To review the pathophysiology, diagnosis, and management of heart failure with diastolic dysfunction.
• To highlight the differences and similarities in management compared to systolic dysfunction.

Main Methods:

• Review of existing literature on diastolic dysfunction and heart failure.
• Analysis of diagnostic criteria and treatment strategies.

Main Results:

• Diastolic dysfunction presents similarly to systolic dysfunction, with comparable rehospitalization rates.
• No large-scale randomized trials guide drug efficacy for diastolic dysfunction.
• Treatment relies on addressing reversible causes and empiric medication use.

Conclusions:

• Management of diastolic dysfunction requires identifying and treating reversible causes.
• Medications used for systolic dysfunction may be employed, but with different dosages and rationale.
• Nursing interventions and patient education are crucial for managing diastolic heart failure.
