64-multyslice computed tomography: detection of coronary artery disease in patients with ischemic heart disease

At present time, the death rate from cardiovascular disease occupies leading position in the structure of total mortality worldwide. The opportunity to conduct non-invasive studies of the coronary arteries has appeared through the development and implementation of multislice computed tomography (MSCT) into medical practice, which carry 64 or more sections. Aim. The purpose of this research is the identification of diagnostic capabilities of 64-slice MSCT in the verification of the severity of coronary artery lesions in patients with proven coronary artery disease. Methods and results. The study has been conducted on a 64-slice CT scanner Optima 660 (GE, USA). The degree of stenosis and calcification of the coronary arteries and also central hemodynamics have been studied. The analysis of survey results of 65 patients with coronary heart disease (30.8% of patients had a history of myocardial infarction) has been carried out. The average age of patients in observation group was 60.2 ± 10.56 years. Male patients were dominated (75.4%). According to the 64-slice MSCT it has been found that coronary artery stenosis occurs ≥ 50% in 90.0% of patients with myocardial infarction, and in 32.5% of patients with symptomatic coronary artery disease. Conclusion. Therefore, MSCT has sufficient specificity in the diagnosis of occlusive and stenotic lesions of the coronary arteries, and can be used for screening patients with suspected coronary artery disease
