Insights
Coronary artery calcification detected by fluoroscopy strongly indicates coronary sclerosis. This non-invasive method is simple, sensitive, and valuable for diagnosing coronary heart disease.
Area of Science:
- Cardiology
- Radiology
Background:
- Coronary heart disease (CHD) is a leading cause of mortality worldwide.
- Accurate non-invasive diagnostic methods for CHD are crucial for early intervention.
Purpose of the Study:
- To evaluate the diagnostic value of coronary artery calcification detected by fluoroscopy in patients with suspected coronary heart disease.
Main Methods:
- Coronary angiography and laevo-cardiography were performed on 236 patients.
- Coronary artery calcification was assessed using fluoroscopy.
- Correlation between calcification presence/severity and coronary angiogram findings was analyzed.
Main Results:
- Coronary artery calcification was present in 47% of patients.
- 97% of patients with calcification showed abnormal coronary angiograms, with 67% having >=50% stenosis.
- A positive correlation was observed between the amount of calcification and stenosis severity.
Conclusions:
- Fluoroscopy-detected coronary artery calcification is a highly probable indicator of coronary sclerosis.
- Fluoroscopy is a simple, sensitive, and valuable non-invasive tool for investigating coronary sclerosis.
Abstract:
Two hundred and thirty-six patients with coronary heart disease were examined by coronary angiography and laevo-cardiography. In 111 patients (47%) there was coronary artery calcification. Of these, 108 patients (97%) showed abnormal findings on the coronary angiogram; in 72 patients (67%) coronary stenosis was greater than or equal to 50% of the lumen. The severity of the stenoses increased with the amount of calcification. There were only three false positive findings and the presence of coronary calcification indicates coronary sclerosis with a high degree of probability. Fluoroscopy is the simplest and most sensitive method of examination and is of great value in the non-invasive investigation of coronary sclerosis.
