Summary

Diastolic heart failure, common in the elderly, involves heart failure symptoms with preserved ejection fraction. Risk factors include age, female gender, hypertension, and diabetes, requiring careful diagnosis and management.

Area of Science:

  • Cardiology
  • Heart Failure Research
  • Geriatric Cardiology

Background:

  • Diastolic heart failure (DHF) presents with heart failure symptoms but preserved left ventricular systolic function (ejection fraction >45%).
  • Its incidence and prevalence increase with age, potentially affecting up to 50% of the elderly population.
  • Key risk factors for DHF include advanced age, female gender, hypertension, coronary artery disease, diabetes, and obesity.

Purpose of the Study:

  • To define diastolic heart failure and outline its clinical presentation.
  • To identify risk factors and discuss the hemodynamic consequences of DHF.
  • To review diagnostic approaches, prognostic factors, and therapeutic strategies for DHF.

Main Methods:

  • Clinical definition based on heart failure symptoms and preserved ejection fraction.
  • Risk factor identification through epidemiological data.
  • Diagnostic recommendations including echocardiography and myocardial stress imaging.
  • Review of prognostic indicators and current therapeutic options.

Main Results:

  • DHF shares hemodynamic consequences with systolic heart failure, including elevated pulmonary venous pressure and reduced cardiac output.
  • Diagnosis relies on preserved ejection fraction; diastolic dysfunction assessment is recommended but not mandatory.
  • B-type natriuretic peptide levels do not differentiate between diastolic and systolic heart failure.
  • Echocardiography and stress imaging are crucial for excluding other cardiac conditions.

Conclusions:

  • Prognosis of DHF is variable, influenced by age, heart failure severity, and comorbidities.
  • Severe DHF carries a prognosis similar to systolic heart failure.
  • Management requires careful use of diuretics/nitrates, essential heart rate control, and pharmacologic agents like ACE inhibitors and ARBs to reduce hypertrophy, with aldosterone antagonists showing potential for fibrosis reduction pending further studies.
