Insights
Chronic renal failure (CRF) patients have a high risk of coronary artery disease. Electron beam CT (EBCT) effectively identifies this risk by measuring coronary artery calcium scores noninvasively.
Area of Science:
- Nephrology
- Cardiology
- Radiology
Background:
- Patients with chronic renal failure (CRF) face elevated risks of cardiovascular disease.
- Assessing coronary artery disease (CAD) risk is crucial for managing CRF patients.
Purpose of the Study:
- To evaluate the risk of coronary artery disease in CRF patients.
- To assess the utility of electron beam CT (EBCT) for measuring coronary artery calcium scores in this population.
Main Methods:
- 81 CRF patients were categorized into pre-dialysis, hemodialysis, and peritoneal dialysis groups.
- Coronary artery calcium scores were measured using EBCT.
- Serum biochemical markers, including calcium and phosphorus products, were analyzed.
Main Results:
- Higher calcium x phosphorus products were observed in dialysis groups compared to pre-dialysis.
- Elevated serum calcium levels were found in the peritoneal dialysis group.
- Patients with higher calcium scores (>400) and those with cardiovascular complications showed significantly higher calcium scores on EBCT.
Conclusions:
- EBCT is a valuable noninvasive tool for assessing coronary artery disease risk in CRF patients.
- CRF patients, particularly those on dialysis, exhibit significant coronary calcification.
- Early identification of CAD risk via EBCT can aid in managing cardiovascular complications in CRF.
Abstract:
We evaluated the risk of coronary-artery disease in patients with chronic renal failure (CRF) by measuring the coronary-artery calcium scores with electron beam CT (EBCT). A total of 81 CRF patients were divided into three groups; pre-dialysis (group I, n = 35), hemodialysis (group II, n = 31) and peritoneal dialysis (group III, n = 15). The several serum biochemical markers and calcium score levels by EBCT were determined. The Ca x P products were significantly higher in groups II (p < 0.05) and III (p < 0.01) than in group I. The serum calcium levels were significantly higher in group III than in both group I (p < 0.01) and II (p < 0.05). The serum calcium level in 15 patients with a calcium score > 400 was significantly higher than the 66 patients with a score < or =400 (p < 0.01). The calcium score was significantly higher in the 15 patients with cardiovascular complications than in the 66 patients without cardiovascular complications (628.9+/-904.8 vs. 150.4+/-350.9, p < 0.01). EBCT seemed to be a good diagnostic tool for evaluating the risk of coronary-artery disease ''noninvasively'' in CRF patients who are at increased risk of cardiovascular morbidity and mortality.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
