The data with respect to stable coronary artery disease (SCAD) are mainly confined to main vessel disease. However, there is a lack of information and long-term outcomes regarding isolated side branch disease. This study aimed to evaluate long-term major adverse cardiac and cerebrovascular events (MACCEs) in patients with isolated side branch coronary artery disease (CAD). A total of 437 patients with isolated side branch SCAD were included. After a median follow-up of 38 months, the overall MACCE and all-cause mortality rates were 14.6% and 5.9%, respectively. Among angiographic features, 68.2% of patients had diagonal artery and 82.2% had ostial lesions. In 28.8% of patients, the vessel diameter was ≥2.75 mm. According to the American College of Cardiology lesion classification, 84.2% of patients had either class B or C lesions. Age, ostial lesions, glycated hemoglobin A1c, and neutrophil levels were independent predictors of MACCE. On the other hand, side branch location, vessel diameter, and lesion complexity did not affect outcomes. Clinical risk factors seem to have a greater impact on MACCE rather than lesion morphology. Therefore, the treatment of clinical risk factors is of paramount importance in these patients.

AbstractObjectiveThe objective of the present study was to examine the relationship between plasma alkyresorcinol (AR) concentrations, which are biomarkers of whole-grain intake, and atherosclerotic progression over 3 years in postmenopausal women with coronary artery disease.DesignPlasma AR concentrations were measured by a validated GC–MS method in fasting plasma samples. Atherosclerosis progression was assessed using change in mean minimal coronary artery diameter (MCAD) and percentage diameter stenosis (%ST), based on mean proximal vessel diameter across up to ten coronary segments. Dietary intake was estimated using a 126-item interviewer-administered FFQ.SettingA prospective study of postmenopausal women participating in the Estrogen Replacement and Atherosclerosis trial.SubjectsFor the analysis of plasma AR concentrations and atherosclerotic progression, plasma samples and follow-up data on angiography were available for 182 women.ResultsMean whole-grain intake was 9·6 (se 0·6) servings per week. After multivariate adjustment, no significant associations were observed between plasma AR concentrations and change in mean MCAD or progression of %ST. Plasma AR concentrations were significantly correlated with dietary whole grains (r=0·35, P<0·001), cereal fibre (r=0·33, P<0·001), bran (r=0·15, P=0·05), total fibre (r=0·22, P=0·003) and legume fibre (r=0·15, P=0·04), but not refined grains, fruit fibre or vegetable fibre.ConclusionsPlasma AR concentrations were not significantly associated with coronary artery progression over a 3-year period in postmenopausal women with coronary artery disease. A moderate association was observed between plasma AR concentrations and dietary whole grains and cereal fibre, suggesting it may be a useful biomarker in observational studies.

Background: The clinical and angiographic predictors of outcomes after percutaneous coronary intervention (PCI) in patients with cancer and radiation associated coronary artery disease (CAD) are not well established. Methods: In this retrospective cohort study, 157 patients with thoracic malignancy and external beam radiation therapy (XRT) prior to PCI were identified. The rates of major adverse cardiovascular and cerebrovascular events (MACCE; all-cause mortality, myocardial infarction, repeat revascularization, or stroke) were compared across patient characteristics. Results: During follow-up of 5.4±4.5 years, 91 (58%) patients had MACCE; 59 (38%) died, of which 23 (39%) were cardiac deaths, 23 (39%) due to cancer or other causes, and 13 (22%) unknown. By Kaplan-Meier analysis, MACCE were more frequent with coronary artery calcification (p=0.023), ostial stenosis (p=0.049), target vessel diameter ≥ 3.0 mm (p=0.018), a SYNTAX score ≥ the median of 11 (p=0.014), or bare metal stenting (BMS) compared to drug-eluting stenting (DES) (p=0.006) (Figure). Cardiac death was more frequent in patients with SYNTAX score ≥ 11 (p=0.028) or BMS (p=0.043). After multivariable adjustment, independent predictors of MACCE were chronic kidney disease (CKD) (p=0.006), New York Heart Association (NYHA) class ≥ 3 (p=0.024), and BMS (p=0.008) (Table). Conclusions: In patients with radiation associated CAD treated with PCI, MACCE is more frequent in those with target vessel calcification, ostial stenosis, large vessel diameter, or SYNTAX score ≥ 11. BMS placement is independently associated with greater MACCE than DES, and other risk factors for MACCE include CKD and NYHA class ≥ 3.

Background: Coronary Artery disease (CAD) is defined as the presence of stenosis of atleast 50% of the vessel diameter in any of the main coronary arteries. Coronary Artery Disease (CAD) is the leading cause of death worldwide. According to WHO estimates, 17.5 million people died of CAD in 2005. Uric acid (UA) is the end product of purine nucleotide metabolism, it could induce the proliferation and inflammation of vascular smooth muscle cells. This study is undertaken to evaluate the role of serum uric acid levels in severity CAD in our centre.Methods: This is a cross sectional study of 120 patients with CAD visiting the OPD or admitted in Medicine department at hospitals attached to BMCRI between June 2018 to July 2019. All CAD patients were assessed for the presence of comorbid conditions and ongoing medications. Serum Uric acid levels, creatinine level, fasting lipid profile were measured in all patients before Coronary Angiogram. The severity of CAD (percentage of stenosis) was assessed by the Gensini scoring system.Results: Of 120 CAD patients’ majority were in the age group of 51-60 years, 89 were men and 31 were women. Of the study patients, 93 (77.5%) symptoms like chest pain and/or breathlessness, 84 (70%) had a smoking history, 43 (35.8) had gensini score of 4 with uric acid levels of (mean 5.49), 26 (21.7%) had gensini score of 8 with uric acid levels of (mean 6.36), 49 (40.8%) had gensini score of 16 with uric acid levels of (mean 7.03) and 2 (1.7%) had gensini score of 32 with uric acid levels of (mean 7.35). Based on this analysis, we found that serum uric acid levels were in linear correlation with the severity of CAD.Conclusions: In conclusion, serum uric acid levels were found to be associated with the severity of CAD.

Abstract The role of inflammation in all phases of atherosclerotic process is well established and soluble TREM-like transcript 1 (sTLT1) is reported to be associated with chronic inflammation. Yet, no information is available about the involvement of sTLT1 in atherosclerotic cardiovascular disease. Present study was undertaken to determine the pathophysiological significance of sTLT1 in atherosclerosis by employing an observational study on human subjects (n=117) followed by experiments in human macrophages and atherosclerotic apolipoprotein E (apoE)−/− mice. Plasma level of sTLT1 was found to be significantly (P<0.05) higher in clinical (2342 ± 184 pg/ml) and subclinical cases (1773 ± 118 pg/ml) than healthy controls (461 ± 57 pg/ml). Moreover, statistical analyses further indicated that sTLT1 was not only associated with common risk factors for Coronary Artery Disease (CAD) in both clinical and subclinical groups but also strongly correlated with disease severity. Ex vivo studies on macrophages showed that sTLT1 interacts with Fcɣ receptor I (FcɣRI) to activate spleen tyrosine kinase (SYK)-mediated downstream MAP kinase signalling cascade to activate nuclear factor-κ B (NF-kB). Activation of NF-kB induces secretion of tumour necrosis factor-α (TNF-α) from macrophage cells that plays pivotal role in governing the persistence of chronic inflammation. Atherosclerotic apoE−/− mice also showed high levels of sTLT1 and TNF-α in nearly occluded aortic stage indicating the contribution of sTLT1 in inflammation. Our results clearly demonstrate that sTLT1 is clinically related to the risk factors of CAD. We also showed that binding of sTLT1 with macrophage membrane receptor, FcɣR1 initiates inflammatory signals in macrophages suggesting its critical role in thrombus development and atherosclerosis.
