Background: Inflammation is a mediator of atherosclerosis progression. However, it remains unclear whether immunoglobulin G4 (IgG4)-related immuno-inflammation may play a specific role in cardiovascular disease. Methods: We used a case-cohort design to analyze the association of serum IgG4 levels with future cardiovascular events. The sample included 561 cases of the primary end point, defined as cardiovascular death, myocardial infarction, ischemic stroke, or unstable angina, and a random subcohort of 1688 (1409 males; mean age, 68.1 ± 8.4 years), of whom 73 were also cases, selected from 12413 eligible participants with stable coronary artery disease in the Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy with Pitavastatin in Coronary Artery Disease (REAL-CAD) study. Results: This case-cohort study had a median follow-up of 3.9 years (interquartile range [IR] 2.9-4.6). Serum IgG4 levels at baseline were 45.3 mg/dL (IR 37.9-58.9), and 845 (50%) took high-dose statins in the subcohort sample. In Cox regression using age, gender, statin dose, high-sensitivity C-reactive protein (hsCRP), body mass index, estimated glomerular filtration rate (eGFR), hypertension, diabetes, and serum lipid profiles, including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides, as covariates, the highest IgG4 quartile was predictive of the primary end point at 4 years (hazard ratio [HR] 1.44, 95% confidence interval [CI] 1.03-2.00, P=0.031), compared with the lowest quartile. Similar results were observed for the secondary end point, a composite of the primary end point plus coronary revascularization (HR 1.60, 95% CI 1.16-2.20, P=0.004). Conclusions: Elevated serum IgG4 level at baseline predicted long-term cardiovascular outcomes independent of established risk factors and high-dose statin therapy in patients with stable CAD. Serum IgG4 may reflect residual cardiovascular risk.

Abstract Background: Suppression of tumorigenesis-2 (ST2) is implicated in myocardial overload and has long been recognized as an inflammation marker related to heart failure and acute coronary syndromes, but data on the prognostic value of ST2 in patients with coronary artery disease (CAD) remain limited. This study sought to investigate the prognostic value of ST2 in patients with established coronary artery disease and its predictive value in CAD patients with or without type 2 diabetes mellitus (T2DM).Methods: A total of 3641 consecutive patients were included in this prospective cohort study. The primary end point was major adverse cardiovascular events (MACEs). The secondary end point was all-cause death. The association between ST2 and outcomes was investigated using multivariable Cox regression.Results: During a median follow-up of 6.4 years, 775 patients had the occurrence of MACEs and 275 patients died. Kaplan-Meier survival estimates indicated that the patients with higher levels of ST2 (ST2> 19 ng/ml) had a significantly increased risk of MACEs (log-rank p＜0.001) and all-cause death (log-rank p<0.001). Multiple Cox regression models showed that higher level of ST2 was an independent predictor for MACEs developments (HR=1.36, 95% CI 1.17-1.56, p<0.001) and all-cause death (HR=2.01, 95% CI 1.56-2.59, p<0.001). The addition of ST2 to established risk factors significantly improved risk prediction of the composite outcome of MACEs and all-cause death (C-statistic, net reclassification index, and integrated discrimination improvement, all p<0.05). Subgroup analyses showed that ST2 remained a significant predictor of MACEs and all-cause death in patients with and without T2DM in multivariable models.Conclusions: A higher level of ST2 is significantly associated with long-term MACEs and all-cause death in CAD patients with and without T2DM. ST2 may provide incremental prognostic value beyond traditional risk factors.

Abstract Background Recent guidelines recommend a target of low density lipoprotein cholesterol (LDL-C) <70 mg/dL in patients at very high risk of cardiovascular disease (CVD). However, a considerable residual risk of CVD persists despite achievement of the LDL-C goal on statin treatment. Purpose This study examined the predictive value of remnant lipoprotein levels for cardiovascular events (CVE) in patients with stable coronary artery disease (CAD) and LDL-C levels <70 mg/dL on statin treatment. Methods Serum levels of remnant lipoproteins (remnant-like lipoprotein particles cholesterol; RLP-C) were measured by an immunoseparation method in 247 consecutive patients with CAD who had on-statin LDL-C levels <70 mg/dL. All the patients were followed prospectively for a period of ≤60 months or until the occurrence of the primary composite endpoint of cardiac death, nonfatal myocardial infarction, unstable angina requiring coronary revascularization, worsening heart failure, peripheral artery diseases requiring endovascular or surgical intervention, aortic events, and ischemic stroke. Results During a mean follow-up period of 38 months, 33 CVEs occurred. Kaplan-Meier estimates in time-to-first-event analysis demonstrated that higher RLP-C levels (>3.9 mg/dL, determined by ROC-curve) resulted in a significantly higher probability for the primary endpoint than did lower RLP-C levels (<3.9 mg/dL) (p<0.01 by log-rank test). Stepwise multivariate Cox proportional hazard analysis showed that RLP-C was a significant predictor of the primary endpoint after adjustment for known risk factors and lipid variables including triglycerides (TG), and total apolipoprotein B (ApoB) (HR 1.62, 95% CI 1.26–2.07, p<0.01). The c-statistics showed that addition of RLP-C had a significant incremental effect on the predictive value of traditional risk factors (area under curve; traditional risk factors: 0.68 vs. traditional risk factors + RLP-C: 0.77, p=0.02). Category-free NRI and IDI demonstrated the additive value of RLP-C to the traditional risk factors plus non-high-density lipoprotein (HDL)-C and ApoB levels (NRI 0.52, p<0.01; IDI 0.06, p<0.01). Conclusions RLP-C levels are a residual risk factor for future CVEs in patients with CAD and on-statin LDL-C <70 mg/dL.

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

Abstract We measured lipid and lipoprotein concentrations in blood samples from control subjects and patients with coronary artery disease (CAD) in Taiwan. We found significant differences (P &lt; 0.01) in the concentrations of high-density lipoprotein cholesterol (HDLC), apolipoprotein AI (ApoAI), apolipoprotein B (ApoB), and lipoprotein(a) [Lp(a)]. Concentrations of HDLC &lt; 350 mg/L, ApoAI &lt; 900 mg/L, ApoB &gt; 800 mg/L, and Lp(a) &gt; 200 mg/L occurred, respectively, 2.8, 5.2, 1.7, and 2.3 times more frequently in the patients than in the control group. If one considers HDLC at &lt; 350 mg/L, ApoAI at &lt; 900 mg/L, ApoB at &gt; 800 mg/L, and Lp(a) at &gt; 200 mg/L as separate risk factors for CAD, the ratio of individual patients to control subjects having 4, 3, 2, 1, or 0 risk factors was [symbol: see text] 9.4, 2.1, 0.2, 0.2, respectively. Individuals displaying three or more risk factors were found 15 times more frequently in the CAD group than in the control group. These risk factors may be used clinically for the prediction and prevention of CAD in the general population.

Abstract Background Coronary artery disease (CAD) is a universal public health challenge, more prominently so in the low- and middle-income countries. In this study, we aimed to determine prevalence and trends of CAD risk factors in patients with documented CAD and to determine their effects on the age of CAD diagnosis. Materials and methods We conducted a registry-based, serial cross-sectional study using the coronary angiography data bank of the Tehran Heart Center. Adult patients who had obstructive (> 50% stenosis) CAD were included in the study. The prevalence and 11-year trends of conventional CAD risk factors were analyzed by sex and age, and their adjusted effects on the age of CAD diagnosis were calculated. Results From January 2005 to December 2015, data for 90,094 patients were included in this analysis. A total of 61,684 (68.5%) were men and 28,410 (31.5%) were women. Men were younger at diagnosis than women, with a mean age of 60.1 in men and 63.2 in women (p < 0.001), and had fewer risk factors at the time of diagnosis. Mean age at diagnosis had an overall increasing trend during the study period. Increasing trend was seen in body-mass index, hypertension prevalence, diabetes mellitus. All lipid profile components (total cholesterol, low-density lipoprotein cholesterol, triglycerides, and high-density lipoprotein cholesterol) decreased over time. Of particular interest, opium consumption was associated with 2.2 year earlier age of CAD diagnosis. Conclusion The major results of this study (lower age of CAD diagnosis in men, lower age of diagnosis associated with most risk factors, and lower prevalence of serum lipids over time) were expected. A prominent finding of this study is confirming opium use was associated with a much younger age of CAD onset, even after adjusting for all other risk factors. In addition to recommendations for control of the traditional risk factors, spreading information about the potential adverse effect of opium use, which has only recently been associated with higher risk of CAD, may be necessary.
