Hypertension frequently causes heart failure, often linked to diastolic dysfunction. Advanced imaging techniques reveal this dysfunction even in early stages and in individuals with a family history of hypertension.

Area of Science:

  • Cardiology
  • Hypertension Research
  • Cardiovascular Disease

Background:

  • Heart failure is a leading cause of cardiovascular morbidity and mortality.
  • Hypertension is the primary driver of cardiac failure.
  • Diastolic dysfunction is a common finding in hypertensive heart disease.

Purpose of the Study:

  • To review current understanding of diastolic function assessment in hypertension.
  • To highlight advancements in echocardiographic and other imaging techniques for evaluating diastolic function.
  • To discuss the role of myocardial ischemia and fibrosis in hypertensive diastolic dysfunction.

Main Methods:

  • Review of invasive and non-invasive methods for assessing diastolic function.
  • Focus on echocardiography (Doppler, tissue Doppler, color M-mode) and newer modalities (MRI, cine CT).

  • Analysis of E and A waves of mitral flow and ventricular time intervals.

    • Main Results:

    • Diastolic dysfunction is prevalent in hypertensive patients, preceding detectable left ventricular hypertrophy.
    • Early diastolic dysfunction can occur in normotensive offspring of hypertensive parents.
    • Myocardial ischemia and fibrosis are identified as key contributors to diastolic dysfunction in hypertension.

    Conclusions:

    • Assessing diastolic function is crucial in managing hypertensive heart disease.
    • Advanced imaging techniques provide valuable insights into diastolic dysfunction.
    • Understanding the underlying mechanisms, including ischemia and fibrosis, is essential for targeted therapies.
