[The indices of intracardiac hemodynamics in patients with postinfarct cardiosclerosis]
Insights
Postinfarction cardiosclerosis patients show reduced left ventricular pump function, especially those with decreased ejection fraction (EF). This decline indicates a need for inotropic medications to enhance myocardial function.
Area of Science:
- Cardiology
- Cardiovascular Physiology
Background:
- Postinfarction cardiosclerosis can impair cardiac function.
- Left ventricular ejection fraction (EF) is a key indicator of cardiac health.
Purpose of the Study:
- To investigate endocardiac hemodynamics in patients with postinfarction cardiosclerosis.
- To correlate ejection fraction (EF) levels with left ventricular pump function.
Main Methods:
- Echocardiographic B- and M-mode techniques were employed.
- Hemodynamics were assessed in 81 patients with varying ejection fractions (EF).
Main Results:
- Patients with postinfarction cardiosclerosis exhibited diminished left ventricular pump function.
- A more pronounced decline in pump function was observed in patients with decreased ejection fraction (EF < 57%).
Conclusions:
- Reduced myocardial pump function in postinfarction cardiosclerosis, even without overt heart failure, warrants intervention.
- Inotropic agents like cardiac glycosides and vasodilators are indicated to improve myocardial contractility.
Abstract:
Endocardiac hemodynamics was studied in 81 patients with postinfarction cardiosclerosis with intact and decreased ejection fraction (EF > 57% and EF < 57% respectively) using echocardiographic B- and M-mode techniques. Patients with postinfarction cardiosclerosis without overt heart failure demonstrated a decline in the left ventricular pump function which was more manifest in postinfarction cardiosclerosis presenting with a decreased ejection fraction. A decline in the pump function of the myocardium in those patients having postinfarction cardiosclerosis without overt cardiac insufficiency is an indication for prescription of those medicinal substances enhancing the inotropic function of the myocardium (cardiac glycosides, peripheral vasodilators).
