Summary
This study found that older patients with ischemic heart disease have more severe coronary artery stenosis. Age significantly correlates with the number of narrowed coronary arteries, with diffuse atherosclerosis more common in those over 40.
Area of Science:
- Cardiology
- Vascular Medicine
- Diagnostic Imaging
Background:
- Ischemic heart disease (IHD) is a major cause of morbidity and mortality.
- Atherosclerotic changes in coronary arteries are the primary pathology in IHD.
- Understanding the relationship between patient age and coronary atherosclerosis severity is crucial for risk stratification and treatment planning.
Purpose of the Study:
- To assess the prevalence and severity of atherosclerotic lesions in the main coronary arteries.
- To investigate the correlation between patient age and the extent of coronary artery stenosis.
- To analyze the impact of age on the pattern of coronary atherosclerosis.
Main Methods:
- Selective coronarography and left ventriculography were performed on 1000 patients with suspected IHD.
- Coronary arteries were assessed for stenosis exceeding 50% of lumen diameter.
- Patients were analyzed in age subgroups (younger and older than 40 years).
Main Results:
- Significant coronary artery stenosis was present in a majority of patients (7.7% no stenosis, 14.5% single artery, 32.8% single significant, 28.5% two arteries, 10.1% three arteries).
- A statistically significant correlation was found between patient age and the number of coronary artery stenoses.
- Diffuse coronary atherosclerosis was more prevalent in patients over 40 years, while younger patients predominantly showed single-artery involvement.
Conclusions:
- Patient age is a significant factor influencing the extent and pattern of coronary artery atherosclerosis.
- Older individuals (>40 years) tend to exhibit more widespread and severe coronary artery disease.
- These findings highlight the importance of age in the evaluation and management of ischemic heart disease.
