Objective Several recent studies have shown that the aldosterone synthase gene ( CYP11B2) −344C/T polymorphism is related to cardiovascular diseases. However, whether the −344C allele influences the incidence of cardiovascular diseases in Chinese patients with hypertension is unclear. Methods Chinese patients with essential hypertension were genotyped for the −344C/T polymorphism in CYP11B2 (n = 755; CC, n = 112; CT, n = 361; TT, n = 282) and followed for 11 years for major adverse cardiovascular events (MACEs), including stroke, onset of coronary artery disease (CAD), and CAD-related death. Established cardiovascular risk factors were used to adjust the multivariate Cox analysis. Results After a mean follow-up period of 7.60 ± 1.12 years, a significantly higher incidence of MACEs was seen in patients with the CC genotype than in those with the CT and TT genotypes. The CC variant was significantly and independently predictive of MACEs (hazard ratio = 2.049), CAD (hazard ratio = 1.754), and stroke (hazard ratio = 2.588), but not CAD-related stroke or death. Conclusion The CYP11B2 −344 CC genotype is a risk factor for CAD and stroke, independent of other established cardiovascular risk factors in Chinese patients with hypertension.

Abstract Background/Introduction Cross-sectional studies are inconsistent on the potential independent adverse effects of human immunodeficiency virus (HIV)-infection on coronary artery disease (CAD). Furthermore, there is no information on the potential effects of HIV-infection on plaque volumes. Also, only the independent effects of HIV-infection on CAD have been investigated. Purpose In a prospective longitudinal observational cohort, we wished to assess whether HIV-infection accelerates CAD independently, or by acting in synergistic fashion with conventional and nonconventional cardiovascular risk factors to accelerate disease progression as assessed by clinical and volumetric parameters of CAD on coronary CT angiography (CCTA). Methods Overall, 300 asymptomatic individuals without cardiovascular symptoms but with CCTA-confirmed coronary plaques (210 males, age: 48.0±7.2 years) with or without HIV (226 HIV-infected) prospectively underwent CCTA at two time points (mean follow-up: 4.0±2.3 years). Agatston-score, number of coronary plaques, segment stenosis score were calculated, and we also segmented the coronary plaques to enumerate total, noncalcified (−100–350HU) and calcified (≥351HU) plaque volumes. Linear mixed models were used to assess the effects of HIV-infection, atherosclerotic cardiovascular disease (ASCVD) risk, years of cocaine use and high-sensitivity C-reactive protein on CCTA markers of CAD. Results In univariate analysis, there was no significant difference in CAD characteristics between HIV-infected and -uninfected, neither at baseline nor at follow-up (p>0.05 for all). Furthermore, there was no significant difference in annual progression rates between the two groups (p>0.05 for all). By multivariate analysis, HIV was not associated with any CAD parameter (p>0.05 for all). However, among HIV-infected individuals, each year of cocaine use significantly increased all CAD parameters (p<0.05 for all), while ASCVD risk score was significantly associated with CAD parameters except for Agatston-score (p<0.05). These associations were only present among HIV-infected individuals. Conclusion(s) Instead of directly worsening CAD, HIV may promote CAD through increased susceptibility to conventional and nonconventional cardiovascular risk factors. Therefore, aggressive management of both conventional and nonconventional cardiovascular risk factors is needed to reduce cardiovascular burden of HIV-infection.

AbstractAim:To compare the growth attainment of preterm children and their cardiovascular risk factors at adolescence with the values measured in term children in Germany.Methods:About 17,641 children aged 0 to <18 years were studied between 2003 and 2006 in the population representative German KiGGS survey (“German Health Interview and Examination Survey for Children and Adolescents”) using questionnaires, physical examinations, standardized anthropometric and blood pressure measurements, and blood sample analyses. Analysis of covariance (ANCOVA) was employed for the analyses of anthropometric parameters.Results:About 11.8% of the 16,737 children with complete and valid data had been born preterm. After adjustment for covariates the estimated z-scores over the total age range were larger in term compared to preterm children for length/height (P<0.001; estimated difference B=0.277, 95% CI 0.191–0.362), head circumference (P<0.001; B=0.238, 95% CI 0.144–0.333), BMI (P=0.001; B=0.160, 95% CI 0.069–0.252), and skinfold thickness (P=0.220; B=0.058, 95% CI −0.035 to 0.151). The onset of pubertal development was slightly (but not significantly) earlier in term compared to preterm children. At 14 to <18 years, anthropometric and biochemical indicators of cardiovascular diseases were not worse in preterm compared to term children.Conclusions:Preterm-born German adolescents remained significantly shorter, lighter, and had a smaller head circumference than term-born adolescents, but the risk indicators for cardiovascular diseases were not higher.

Thrombin generation may be a potential tool to improve risk stratification for cardiovascular diseases. This study aims to explore the relation between thrombin generation and cardiovascular risk factors, cardiovascular diseases, and total mortality. For this study, N=5000 subjects from the population-based Gutenberg Health Study were analysed in a highly standardized setting. Thrombin generation was assessed by the Calibrated Automated Thrombogram method at 1 and 5 pM tissue factors trigger in platelet poor plasma. Lag time, endogenous thrombin potential, and peak height were derived from the thrombin generation curve. Sex-specific multivariable linear regression analysis adjusted for age, cardiovascular risk factors, cardiovascular diseases and therapy, was used to assess clinical determinants of thrombin generation. Cox regression models adjusted for age, sex, cardiovascular risk factors and vitamin K antagonists investigated the association between thrombin generation parameters and total mortality. Lag time was positively associated with obesity and dyslipidaemia for both sexes (p<0.0001). Obesity was also positively associated with endogenous thrombin potential in both sexes (p<0.0001) and peak height in males (1 pM tissue factor, p=0.0048) and females (p<0.0001). Cox regression models showed an increased mortality in individuals with lag time (1 pM tissue factor, hazard ratio=1.46, [95% CI: 1.07; 2.00], p=0.018) and endogenous thrombin potential (5 pM tissue factor, hazard ratio = 1.50, [1.06; 2.13], p=0.023) above the 95th percentile of the reference group, independent of the cardiovascular risk profile. This large-scale study demonstrates traditional cardiovascular risk factors, particularly obesity, as relevant determinants of thrombin generation. Lag time and endogenous thrombin potential were found as potentially relevant predictors of increased total mortality, which deserves further investigation.

Rheumatoid arthritis is a frequent and one of the most severe immuno-inflammatory diseases in humans, which determines the great medical and socio-economic importance of this pathology. One of the priority problems of modern cardiac rheumatology is an increased risk of cardiovascular complications in rheumatoid arthritis. In patients with rheumatoid arthritis, traditional cardiovascular risk factors for cardiovascular diseases (metabolic syndrome, obesity, dyslipidemia, arterial hypertension, insulin resistance, diabetes mellitus, smoking and hypodynamia) and a genetic predisposition are expressed. Their specific features also have a certain effect: the “lipid paradox” and the “obesity paradox”. However, chronic inflammation as a key factor in the development of progression of atherosclerosis and endothelial dysfunction plays a leading role in morbidity and mortality from cardiovascular diseases in rheumatoid arthritis. This review discusses the effect of chronic inflammation and its mediators on traditional cardiovascular risk factors and its independent significance in the development of CVD. Drug therapy (non-steroidal anti-inflammatory drugs, glucocorticosteroids, basic anti-inflammatory drugs, genetically engineered biological drugs) of the underlying disease also has a definite effect on cardiovascular risk factors in patients with rheumatoid arthritis. A review of studies on this problem suggests a positive effect of pharmacological intervention in rheumatoid arthritis on cardiovascular risk factors, their reduction to a level comparable to the populations of patients not suffering from rheumatoid arthritis. The interaction of rheumatologists, cardiologists and first-contact doctors (therapist and general practitioner) in studying the mechanisms of the development of atherosclerosis in patients with rheumatoid arthritis will allow in real clinical practice to develop adequate methods for the timely diagnosis and prevention of cardiovascular diseases in patients with rheumatoid arthritis.

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
