Insights
Sixty-four slice multi-detector computed tomography (MDCT) coronary angiography is a reliable, non-invasive method for diagnosing coronary artery disease. With 92% sensitivity and 86% positive predictive value, it effectively aids in excluding coronary artery disease.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Cardiovascular diseases, particularly coronary artery disease, are a leading cause of mortality in European countries, accounting for over 50% of deaths.
- Myocardial infarction is significantly more prevalent in men than women before age 75.
Purpose of the Study:
- To evaluate the diagnostic accuracy of 64-slice multi-detector computed tomography (MDCT) coronary angiography.
- To compare MDCT coronary angiography with invasive coronary angiography for detecting coronary artery disease.
Main Methods:
- A study involving 50 patients (average age 60) of both genders.
- All participants underwent both CT coronary angiography and conventional invasive coronary angiography.
Main Results:
- MDCT coronary angiography demonstrated a sensitivity of 92% and a positive predictive value (PPV) of 86%.
- Significant differences were observed in evaluating stenosis of the circumflex artery (CX) between the two methods.
- No statistically significant differences were found in the analysis of the left anterior descending (LAD) and right coronary artery (RCA) between CT and invasive angiography.
Conclusions:
- CT coronary angiography is a non-invasive, comfortable, and dependable diagnostic tool for coronary artery disease.
- Its high sensitivity and PPV facilitate the reliable exclusion of coronary artery disease.
- MDCT coronary angiography holds a significant position within the diagnostic algorithm for cardiovascular diseases.
Introduction:
Cardiovascular disease, among which the most common is coronary disease of the hearth are the main cause of death at middle aged persons in the majority of European countries. Percent of cardiovascular disease in overall mortality among our population is even more than 50%. Up to 55 years of live myocardial infarction is by 5-6 times more common among men, and up to age of 75 years that difference decreases to 2.5 times.
Goal:
The goal of this study is to determine the diagnostic value of 64 slices computerized tomography in detection of coronary disease compared to classic, invasive coronography.
Material And Methods:
Study included 50 patients, of both genders, at average age of 60 years. Patients underwent CT coronography as well as classic coronography.
Results:
Our research prove that the sensitivity of MSCT coronography 92% with positive predictive value of 86%. Mayor difference was in the analysis of CX artery in the evaluation of significant and non-significant stenosis in application of these two methods. During the analysis of LAD and RCA artery there was no statistically significant difference in findings of these two methods.
Conclusion:
CT coronography is non-invasive, comfortable and reliable method in coronary disease diagnostics. Thanks to its high sensitivity and PPV it enables reliable exclusion of coronary disease and takes significant place in a cardiovascular diseases diagnostic algorithm.

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...
