[An evaluation of left ventricular myocardial function by x-ray and electrocardiographic data in patients with
Insights
X-ray imaging can noninvasively assess left ventricular function in patients with coronary artery disease. End systolic volume and relative heart volume correlate closely, aiding in patient follow-up.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Postinfarction cardiosclerosis impacts heart function.
- Assessing left ventricular function is crucial for managing coronary artery disease.
- Noninvasive methods for monitoring cardiac function are highly desirable.
Purpose of the Study:
- To evaluate the diagnostic value of chest x-ray criteria for heart function in postinfarction cardiosclerosis patients.
- To compare radiographic findings with coronary-ventricular and electrocardiographic data.
- To explore the utility of x-ray methods in the follow-up of coronary artery disease patients.
Main Methods:
- Comparison of x-ray data with coronary-ventricular and electrocardiographic findings.
- Inclusion of patients in two age groups: 22-39 years (Group I) and 60-69 years (Group II).
- Analysis of end systolic volume and relative heart volume as x-ray indicators.
Main Results:
- Younger patients (Group I) exhibited more pronounced left ventricular functional alterations than older patients (Group II) for similar coronary artery lesions.
- A strong correlation was observed between end systolic volume and relative heart volume.
- X-ray indicators show potential for assessing left ventricular function.
Conclusions:
- X-ray criteria, specifically the correlation between end systolic volume and relative heart volume, can serve as a noninvasive method for assessing left ventricular function.
- This radiographic approach is valuable for the follow-up of patients with coronary artery disease.
- Age influences the manifestation of functional alterations in postinfarction cardiosclerosis.
Abstract:
To determine the diagnostic significance of x-ray criteria for assessing heart function in patients with postinfarction cardiosclerosis, the coronary-ventricular and electrocardiographic findings were compared with x-ray data in patients of 2 age groups. Group I was made up of patients aged 22 to 39 years, group II of patients aged 60 to 69 years. An attempt was made to base the use of the x-ray method during follow-up of patients suffering from coronary disease. With lesions of the coronary arteries being the same, the functional alterations in the left ventricle were more pronounced in younger patients than in elderly ones. The presence of a sufficiently close correlation between the end systolic volume and the relative heart volume makes it possible to employ this x-ray indicator as a noninvasive criterion for assessing left ventricular function during follow-up of patients with coronary disease.
