Summary

Assessing diastolic cardiac function requires multiple parameters due to its complex active and passive factors. Comprehensive evaluation, including invasive and noninvasive methods, is crucial for accurate diagnosis and effective therapy in heart conditions.

Area of Science:

  • Cardiology
  • Cardiovascular Physiology

Background:

  • Diastolic cardiac function is increasingly recognized for early detection of cardiac disease.
  • It involves complex active and passive factors, necessitating a multi-parameter assessment.

Purpose of the Study:

  • To review various diastolic function parameters.
  • To discuss their role in assessing cardiac function and responsiveness to therapy in conditions like hypertrophy, cardiomyopathy, and coronary heart disease.

Main Methods:

  • Comprehensive analysis requires invasive procedures (pressure and volume measurements) and noninvasive techniques (echocardiography, radionuclear ventriculography).
  • Assessment includes filling parameters, stress-strain relationships, and complementary diagnostics like pulmonary pressure and stress testing.

Main Results:

  • No single parameter is sufficient for a complete diastolic function analysis.
  • Therapies must consider potential impacts on diastolic function, especially concerning myocardial oxygen consumption.

Conclusions:

  • Effective evaluation of diastolic cardiac function integrates invasive and noninvasive diagnostics.
  • Understanding parameter responsiveness to therapy is key for managing cardiac conditions.
