Association of epicardial adipose tissue with cardiovascular risk factors in subjects free from clinical symptoms of coronary artery disease

Aim. To determine the expression of adiponectin, leptin and I interleukin-6 (IL-6) in subcutaneous, epicardial and perivascular adipose tissue, depending on the presence of cardiovascular risk factors.Material and methods. The study included 90 patients with stable coronary artery disease (CAD) who underwent coronary artery bypass grafting. Samples of adipose tissue were obtained during surgery. The levels of matrix ribonucleic acid (mRNA) of the studied adipocytokines were determined in the presence/absence of the main cardiovascular risk factors.Results. Differences in the expression of genes of the studied adipocytokines in different sex and age groups of patients were revealed, depending on the tissue belonging of adipocytes. Expression of adiponectin in the epicardial and perivascular adipose tissue (EАT and PVAT, respectively), as well as of leptin in the PVAT was less pronounced in men. However, the level of IL-6 mRNA in the subcutaneous adipose tissue (SAT) of men was three times higher than in women, and in the PVAT it was lower. The maximum expression of leptin and IL-6 in the EAT and PVAT was found in persons aged 50-59 years. The presence of dyslipidemia is associated with a decrease in the expression of adiponectin in the EAT, PVAT, and IL-6 in the PVAT. In patients with hypertension (HTN), there was a low level of adiponectin mRNA in the EAT against the background of high leptin levels in the EAT and IL-6 in SAT and EAT. In hypertension with a duration of more than 20 years, there was a decrease in adiponectin expression and an increase in leptin in all types of AT. In smokers, an increase in the expression of adiponectin in the SAT, EAT, PVAT and leptin in the SAT, EAT was found.Conclusion. Associations of traditional cardiovascular risk factors with imbalance of adipocytokines of local fat depots in patients with CAD were revealed. The detected imbalance is manifested by a decrease in the expression of cardioprotective adiponectin in the EAT, PVAT, an increase in leptin and IL-6, which is an unfavorable sign. The presence of such risk factors as male sex, age of 50-59 years, dyslipidemia and hypertension in patients can enhance atherogenesis and contribute to the further progression of CAD.

BACKGROUND Routine screening of healthy individuals for the presence of cardiovascular risk factors is important for identification of high-risk coronary artery disease (CAD) patients at early stage and to provide preventive care. Considering the high burden of CAD, such investigations are of significant importance in Indian context. METHODS In this cross-sectional study, adult individuals (18 – 68 years) were evaluated for pre-existing diseases, lipid profile, blood glucose profile, thyroid profile, haemoglobin (Hb) and vitamins D3 and B12 levels after obtaining informed consent. These variables were compared between patients stratified based on their gender and age (< 40, 40 – 60, > 60 years). RESULTS A total of 1,508 participants (mean age: 49 ± 11 years; 49.9 % females) were investigated. Hypertension, diabetes, dyslipidaemia, anaemia, vitamin D3 and B12 deficiencies, hyperthyroidism, and hypothyroidism were observed in 31.2 %, 26.5 %, 32.0 %, 8.6 %, 35.3 %, 25.1 %, 21.0 % and 0.6 % of patients respectively. Prevalence of hypertension, diabetes, and dyslipidaemia increased with ageing, while deficiencies of Hb, vitamin D3, and vitamin B12 as well as hyperthyroidism and hypothyroidism were comparable across all age groups. Males were more prone to hypertension, diabetes, and dyslipidaemia, while females were more prone to have Hb deficiency, hyperthyroidism, and hypothyroidism. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), fasting blood sugar (FBS), vitamin D3, and vitamin B12 were elevated with increase in age, while Hb levels decreased. Males exhibited higher levels of TG, low-density lipoprotein cholesterol (LDL-C), TC / HDL, LDL / HDL, FBS, and Hb, while females displayed higher levels of vitamin D3 and B12. CONCLUSIONS Our findings verify the role of age and gender on majority of cardiovascular risk factors. The high prevalence of cardiovascular risk factors is alarming and demands the need for appropriate health-care measures. KEYWORDS Age, Coronary Artery Disease, Gender, Risk Factor

Artery Disease

Premature coronary atherosclerosis, which is actually seen as an active inflammatory process, is an established complication of systemic autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). We hypothesized that exposure to chronic inflammation, even in the absence of classical cardiovascular risk factors (CVRF), could result in coronary microvascular dysfunction (CMD), an early marker of coronary atherosclerosis. By means of positron emission tomography in combination with oxygen-15 labeled water, myocardial blood flow (MBF) was measured at rest and during iv adenosine infusion (140 μg/kg/min) in 13 SLE and 12 RA patients (mean [±SD] age 44±10 years) without CVRF. All patients underwent coronary angiography using multi-slice (64 slices) computed tomography and only those with none or trivial coronary artery disease (<30% luminal stenosis) were included. A group of 25 age- and gender-matched controls were also studied. There were no differences between patients and controls regarding body-mass index, blood pressure and lipid parameters. RA and SLE patients showed similar mean disease duration (16±11 and 11±7 years, respectively; p=0.12). Resting MBF was similar in patients and controls (1.25±0.27 vs 1.15±0.24 ml/min/g, p=0.15). However, during adenosine stress patients had lower MBF compared with controls (2.94±0.83 vs 4.11±0.84 ml/min/g, p<0.001). As result, coronary flow reserve (CFR; adenosine/resting MBF) was significantly reduced in patients (2.44±0.78) compared with controls (3.81±1.07; p<0.001). Seven patients showed ischemic electrocardiographic changes during adenosine and had a more severe reduction in CFR (1.76±0.81) and more years of disease (21±7 years) compared with those patients without ischemic changes (CFR 2.49±0.54; p=0.006; duration of disease 14±5 years; p=0.03). CFR was inversely correlated with years of disease (r=−0.65, p<0.001), but not with corticosteroid cumulative dose (r=0.20, p=0.39). Chronic inflammation in the absence of traditional CVRF is characterized by severe CMD. This may represent an early marker of disease which precedes and contributes to premature coronary artery disease in patients with RA and SLE.

Abstract Background Lower-extremity peripheral artery disease (LE-PAD) and coronary artery disease (CAD) are both pathologically rooted in atherosclerosis, and their shared clinical features regarding the exposure to cardiovascular risk factors have been emphasized. However, comparative data of the two cardiovascular diseases (CVDs) were so far lacking. The purpose of this study was to directly compare the clinical profile between cases undergoing endovascular therapy (EVT) for LE-PAD and those undergoing percutaneous coronary intervention (PCI). Methods Data were extracted from the nationwide procedural databases of EVT and PCI in Japan (J-EVT and J-PCI) between 2012 and 2017. A total of 1,121,359 cases (103,887 EVT cases for critical limb ischemia [CLI] or intermittent claudication and 1,017,472 PCI cases for acute coronary syndrome [ACS] or stable angina) were analyzed. Heterogeneity in clinical profile between CVDs was evaluated using the C statistic of the logistic regression model for which dependent variable was one CVD versus another, and explanatory variables were clinical profile. When two CVDs were completely discriminated from each other by the developed model, the C statistic (discrimination ability) of the model would be equal to 1, indicating that the two CVDs were completely different in clinical profile. On the other hand, when two CVDs were identical in clinical profile, the developed model would not discriminate them at all, with the C statistic equal to 0.5. Results Mean age was 73.5 ± 9.3 years in LE-PAD patients versus 70.0 ± 11.2 years in CAD patients (P < 0.001). The prevalence of diabetes mellitus and end-stage renal disease was 1.96- and 6.39-times higher in LE-PAD patients than in CAD patients (both P < 0.001). The higher prevalence was observed irrespective of age group. The exposure to other cardiovascular risk factors and the likelihood of cardiovascular risk clustering also varied between the diseases. The between-disease heterogeneity in patient profile was particularly evident between CLI and ACS, with the C statistic equal to 0.833 (95% CI 0.831–0.836). Conclusions The current study, an analysis based on nationwide procedural databases, confirmed that patient profiles were not identical but rather considerably different between clinically significant LE-PAD and CAD warranting revascularization.
