[Prognostic significance of equivalent density of calcium deposits of coronary arteries in men with osteopenic syndrome and prior coronary artery bypass grafting: prospective study].

AIM: Determination of the clinical and prognostic value of the equivalent density of calcium deposits (EDCD) of coronary arteries in patients with stable coronary heart disease (CHD) and concomitant osteopenic syndrome (OS) after coronary artery bypass grafting (CABG), based on five-year follow-up. MATERIALS AND METHODS: A prospective study included 393 patients with stable CHD hospitalized for CABG. All patients underwent multispiral computed tomography of coronary arteries to assess the degree of calcification and EDCD, and Х-ray absorptiometry. During the five-year observation we studied mortality and adverse cardiovascular events. The average duration of the observation period was 58.91.8 months. RESULTS: Data were obtained on the correlation of EDCD with the presence of OS (r=0.19; p0.001), a decrease in the T-criterion of the thigh (r=-0.21; p0.001) and lumbar vertebrae (r=-0.19; p0.001). With a decrease in the EDCD of coronary arteries below the level of 0.19 mg/mm3, an increased mortality risk is noted (odds ratio 2.84, 95% confidence interval 1.545.25). Linear regression analysis revealed that predictors of adverse outcomes over the course of a follow-up were the presence of carotid artery stenosis 30%, low left ventricular contractility, elevated triglyceride levels, and low EDCD. CONCLUSION: According to the results of the study the negative prognostic significance of the low EDCD of coronary arteries in relation to mortality, myocardial infarction, and revascularization in patients after CABG, regardless of the presence of concomitant OS.

[Relationship of visceral obesity and coronary calcinosis in ischemic heart disease].

AIM: To assess the relationship between the prevalence of visceral obesity (VO) and the severity of coronary calcification (CC) in patients with verified coronary artery disease (CAD). MATERIALS AND METHODS: 125 patients with CAD were examined. Assessment of the morphometric characteristics of visceral adipose tissue (VAT) and CC was perform using multislice computed tomography (MSCT). The calcium index (CI) of the coronary arteries (CA) was determine by the Agatston method. Statistical analysis was perform using Statistica 10.0. RESULTS: VO was detect in 82 (65.6%) patients with CAD. In the presence of VO, higher CC values were observed in the projection of the envelope (p=0.00014), right coronary (p=0.00002) arteries, total CI (p=0.0003), and the prevalence of massive CC. Correlation analysis showed the relationship between the area of VAT and the CC of all the studied localizations. According to the ROC analysis, VO is a significant predictor of massive CC (area under the ROC curve AUC 0.72, 95% CI 0.560.89), in contrast to body mass index BMI (AUC 0.56, 95% CI 0.310.82). CONCLUSION: The index of the ratio of VAT to subcutaneous adipose tissue (VAT/SAT), but not BMI, had a direct correlation with CC. Morphology of VAT may be a significant diagnostic sign of massive CC in patients with CAD, as a factor affecting treatment and prognosis.

[Evaluation of coronary artery lesion in men with osteopenic syndrome and coronary artery disease].

AIM: To examine the relation between coronary atherosclerosis (CA), coronary artery calcification (CAC), and bone mineral density (BMD) in men with coronary artery disease (CAD). SUBJECTS AND METHODS: The investigation included 74 males aged 60.1 (range, 55-70) years with verified CAD. All the patients underwent X-ray contrast-enhanced selective coronary angiography and coronary artery calcium score (CS) and BMD measurements by osteodensitometry. The severity of a coronary artery lesion was evaluated using the SYNTAX score. According to the T score, the patients were divided into 3 groups: 1) 23 patients with osteoporosis (OP), 2) 30 patients with osteopenia, and 3) 21 patients with normal BMD. RESULTS: Osteopenic syndrome (OS) (OP and osteopenia) was found in 71.6% of the patients with angiographically confirmed CAD. Single-vessel lesion in the coronary bed (CB) was more frequently recorded in the normal BMD group than in the OP one (p = 0.023). Severe CB lesion was more common for the patients with OP (p = 0.029). There were statistically significant differences between the osteopenia and normal BMD groups in the severe degree of CB lesion (p = 0.042). Differences were noted in total CS between Groups 1 and 2 (p = 0.0122). CS significantly correlated with the severity of CA lesion according to the SYNTAX score (r = 0.53; p = 0.002). CONCLUSION: Severe CB lesion in males correlates with CAC and is associated with decreased BMD, suggesting the commonness of the pathogenetic components of AS and OS.
