[The significance of investigation of the left ventricle diastolic function in cardiosurgery]
Insights
Assessing left ventricular diastolic function alongside systolic parameters is crucial for evaluating outcomes in acquired heart disease and ischemic heart disease patients. Surgical correction can significantly improve diastolic dysfunction and reduce pulmonary hypertension.
Area of Science:
- Cardiology
- Cardiac Surgery
- Cardiovascular Physiology
Background:
- Patients with congenital, acquired, and ischemic heart disease (IHD) require comprehensive assessment for operative treatment.
- Evaluating left ventricular (LV) function is critical, but diastolic parameters are often overlooked.
- Diastolic dysfunction can be caused or exacerbated by conditions like volume/pressure overload and myocardial ischemia.
Purpose of the Study:
- To emphasize the necessity of assessing left ventricular (LV) diastolic function in patients with acquired heart disease and IHD.
- To determine the impact of cardiosurgical correction on LV diastolic dysfunction and pulmonary hypertension.
Main Methods:
- Examination of 79 patients with various heart diseases and 64 age-matched controls.
- Assessment of systolic and diastolic function parameters of the left ventricle (LV).
- Evaluation of LV filling patterns (monophasic vs. biphasic) and pulmonary artery pressure pre- and post-operatively.
Main Results:
- Testing diastolic function of the left ventricle (LV) is necessary to improve the assessment of operative treatment outcomes for acquired heart disease and IHD.
- Cardiosurgical correction can eliminate or reduce LV diastolic dysfunction caused by volume/pressure overload or ischemia.
- A pathological monophasic LV filling pattern indicates severe systole-diastolic dysfunction and pulmonary hypertension.
- Radical surgery restores biphasic LV filling and reduces pulmonary artery pressure.
Conclusions:
- Left ventricular (LV) diastolic function assessment is vital for evaluating surgical outcomes in acquired heart disease and IHD.
- Cardiosurgical interventions can effectively manage LV diastolic dysfunction and associated pulmonary hypertension.
- Restoration of normal LV filling patterns post-surgery signifies improved cardiac function and reduced pulmonary vascular resistance.
Abstract:
An examination of 79 patients (main group) with congenital, acquired heart diseases and ischemic heart disease (IHD) without activity of the rheumatoid process and infectious endocarditis and 64 subjects of the same age has shown that in order to improve the assessment of the results of operative treatment of patients with the acquired heart disease and IHD it is necessary to test the diastolic function of the left ventricle (LV) in addition to the systole parameters. Cardiosurgical correction of pathological processes either causing or aggravating LV diastolic dysfunction (overloading LV with the volume or pressure, myocardium ischemia) can either eliminate or reduce its degree. A pathological monophasic filling of LV is a sign of a pronounced systole-diastolic dysfunction of LV and lung hypertension. A radical operative intervention reestablishes the biphasic filling of LV and reduces pressure in the pulmonary artery.
