Summary

Hypertension can cause diastolic dysfunction, leading to heart failure even with normal systolic function. This review covers causes, measurement tools, and treatments for diastolic heart failure in hypertensive patients.

Area of Science:

  • Cardiology
  • Internal Medicine
  • Hypertension Research

Background:

  • Diastolic dysfunction is a significant cause of heart failure, particularly in hypertensive individuals.
  • A substantial proportion of patients with heart failure symptoms exhibit preserved systolic function but impaired diastolic function.
  • Hypertension is a primary risk factor contributing to the development of diastolic dysfunction.

Purpose of the Study:

  • To review the pathophysiologic mechanisms underlying diastolic dysfunction in hypertension.
  • To discuss current and novel diagnostic tools for assessing diastolic function.
  • To explore contemporary treatment strategies for patients with diastolic heart failure.

Main Methods:

  • Literature review of pathophysiologic factors in diastolic dysfunction.
  • Analysis of current and emerging diagnostic modalities for diastolic function assessment.
  • Synthesis of current treatment concepts for diastolic heart failure.

Main Results:

  • Diastolic dysfunction can manifest asymptomatically or as severe pulmonary edema in hypertensive patients.
  • Normal left ventricular systolic function is observed in up to 40% of hypertensive patients with congestive heart failure.
  • Understanding pathophysiologic factors is crucial for effective management.

Conclusions:

  • Diastolic dysfunction is a key contributor to heart failure in hypertension, often with preserved ejection fraction.
  • Accurate assessment of diastolic function is vital for diagnosis and management.
  • Targeted therapeutic approaches are essential for improving outcomes in patients with diastolic heart failure.
