[Left ventricular systolic function in patients with infectious allergic myocarditis]

Area of Science:

• Cardiology
• Nuclear Medicine

Background:

• Infectious-and-allergic myocarditis and myocarditic cardiosclerosis can affect cardiac function.
• Left ventricular systolic function is a key indicator of heart health.

Purpose of the Study:

• To assess left ventricular systolic function in patients with infectious-and-allergic myocarditis and myocarditic cardiosclerosis.
• To investigate the relationship between cardiac function and clinical presentation.

Main Methods:

• Radionuclide ventriculography was used to examine 26 patients with infectious-and-allergic myocarditis and 12 with myocarditic cardiosclerosis.
• Measurements included end-systolic volume and mean myocardial fiber circular shortening rate.

Main Results:

• Impairment of left ventricular systolic function was observed in both patient groups.
• A downward tendency was noted in end-systolic volume and mean myocardial fiber circular shortening rate.
• A correlation was found between systolic function alterations and the clinical pattern.

Conclusions:

• Radionuclide ventriculography is effective in detecting systolic dysfunction in myocarditis and cardiosclerosis.
• Cardiac function abnormalities are linked to the clinical manifestation of these heart conditions.
