Congestive heart failure arising from diastolic dysfunction in the presence of normal left-ventricular systolic function

Area of Science:

• Cardiology
• Geriatrics

Background:

• Congestive heart failure (CHF) with preserved systolic function, often due to diastolic dysfunction, is common, especially in the elderly.
• These patients present with typical CHF symptoms but normal left ventricular (LV) systolic function.

Purpose of the Study:

• To outline a diagnostic approach for CHF patients with normal systolic function.
• To highlight the clinical characteristics, prognosis, and treatment challenges of diastolic dysfunction.

Main Methods:

• Review of clinical presentation and diagnostic considerations for diastolic dysfunction.
• Analysis of existing literature on treatment trials and outcomes for diastolic dysfunction.

Main Results:

• Patients with diastolic dysfunction have a better prognosis than those with LV systolic dysfunction.
• Limited clinical trials specifically target diastolic dysfunction, unlike LV systolic failure.

Conclusions:

• A thorough diagnostic work-up is crucial to identify and manage contributing factors in CHF with normal systolic function.
• Symptomatic relief is achievable with tailored therapy, but further research on long-term outcomes and specific treatments for diastolic dysfunction is warranted.
• Advancements in noninvasive imaging and hemodynamic assessments hold promise for improving patient care.
