ABSTRACT
AIM: To determine the frequency, distribution and characteristics of ectopic obesity in patients without manifested cardiovascular disease. MATERIALS AND METHODS: We examined 320 patients without manifested cardiovascular disease (average age 63.813.9 years), 38 of them without cardiovascular risk factors (healthy referent group). Anthropometric indicators were measured, body mass index (BMI) was calculated. Degree, type of obesity, lipid profile were evaluated. All patients underwent multi-detector chest computed tomography in spiral mode on Toshiba Aquilion Prime scanner using standardized protocol. Perivascular adipose tissue (PVAT) and pericardial adipose tissue (PAT) were detected using specialized semi-automatic software Tissue Composition Module QCTPro (Mindways Software, Inc., USA) after scanner calibration with special phantom. PAT and PVAT exceeding the 90th percentile in the healthy referent group were considered as ectopic obesity. Statistical analysis was performed using Statistica 10.0 software (StatSoft Inc., USA). RESULTS: PAT volume 3.2 cm3 and PVAT volume 0.4 cm3 were criteria for high pericardial and high perivascular fat; 81 (25.2%) patients had ectopic obesity, 85 (26.5%) patients abdominal obesity; 146 (42.9%) people had high pericardial fat, 134 (39.4%) high perivascular fat. The frequency of ectopic obesity in patients with arterial hypertension (AH) was statistically significantly higher compared to persons without AH. Significantly more often ectopic forms of obesity were detected in patients with overweight and obesity. The high pericardial fat and high perivascular fat were found in patients with overweight and normal body weight. When comparing the clinical characteristics of patients with abdominal and ectopic obesity, metabolic parameters, as well as the incidence of hypertension and dyslipidemia, did not differ significantly. CONCLUSION: Ectopic obesity can develop outside of global obesity. In addition, this type of obesity is accompanied by metabolic disorders and AH, regardless of the abdominal distribution of adipose tissue.

In Russia, target blood pressure (BP) levels are achieved in only 14.4% of men and in 30.9% of women. The need for combination therapy of hypertension is as high as 70.7%. There are well-known benefits of combined antihypertensive therapy allowing for higher efficiency and better tolerability. One of the current combinations is a combination of an angiotensin-converting enzyme inhibitor and a calcium antagonist, which have pronounced protective activity and metabolic neutrality. Fixed-dose combinations have substantial advantages over free ones, contributing to improving patient compliance with the used treatment regimen. Dyslipidemia is present in 60.7% of the hypertensive patients. Nonetheless, only 9.7% of Russian patients with coronary heart disease take statins and control of lipid levels remains very poor. The review discusses whether the use of the triple combination lisinopril + amlodipine + rosuvastatin is reasonable from the standpoint of evidence-based medicine. There are literature data suggesting the high value of this fixed-dose combination in the context of organ protection and the reduced risk of cardiovascular events.
