Objectives: Although there are many studies assessing the relationship between carotid artery ultrasound findings and coronary artery disease, the relationship between carotid plaque types and the complexity of coronary lesions is not assessed. We aimed to examine the relationship between the SYNTAX score and carotid plaque morphology. Patients and Methods: We retrospectively screened patients who underwent carotid Ultrasound before the coronary artery bypass graft operation between 2015 and 2020. Syntax score was calculated by two independent interventional cardiologists with online SYNTAX score calculator (www.syntaxscore.com). The lesions of carotid arteries by ultrasound were classified as fibrous, calcific and mixed plaques. Results: A total of 407 patients were enrolled. Median age was 65 (58-71) years and 81.6% of patients were male. We used multinomial logistic regression to test the association between plaque types and syntax score. The syntax score was associated with calcified plaque both in right (odds ratio 1.04, 95% CI 1.01-1.07, p=0.006) and left internal carotid artery (odds ratio 1.04, 95% CI 1.02-1.06, p=0.004). However, the syntax score was not associated with fibrous (odds ratio 0.97, 95% CI 0.94-1.01, p=0.155 for right and odds ratio 0.99, 95% CI 0.96-1.02, p=0.759 for left carotid artery) and mixed plaque types (odds ratio 1.02, 95% CI 0.98-1.06, p=0.168 for right and odds ratio 1.00, 95% CI 0.96-1.04, p=0.791 for left carotid artery). Conclusion: Syntax score may provide an idea for carotid plaque morphology prediction. Especially higher SYNTAX score may be a predictor of calcific carotid plaque.

Aim: The aim of this study was to assess the association between PEAR1 polymorphisms and ischemic clinical outcomes. Materials & methods: We searched the electronic database for articles on the relationship of PEAR1 SNPs and ischemic events in patients with coronary artery disease (CAD) up to October 2020. Results: A total of 9914 patients with CAD from six studies focusing on 12 SNPs of PEAR1 were included in this study. The A allele of rs12041331 were associated with ischemic events (odds ratio: 1.40; 95% CI: 1.04–1.88; p = 0.03). The AA homozygotes of rs2768759 was related to a higher risk of ischemic events than carriers of the C allele (odds ratio: 2.08; 95% CI: 1.09–3.97; p = 0.03). Conclusion: PEAR1 rs12041331 and rs2768759 are significantly associated with ischemic events in patients with CAD.

Introduction: Sex differences in plaque morphology and composition exist; men develop more unstable plaques than women. Yet, stroke kills more women than men. Despite these differences, no sex-specific guidelines for carotid disease management exist. Thus, markers that reflect sex-specific morphological features in the plaque should be explored for better prediction of stroke risk. Pro-inflammatory adipokines, chemerin and resistin, influence vascular function. Herein we are the first to investigate sex differences in the relationship between carotid plaque instability and the expression of these adipokines. Methods: Subjects with ≥50% carotid stenosis scheduled for a carotid endarterectomy were recruited from McGill-affiliated hospitals. Pre-operative plasma chemerin and resistin levels were measured using ELISA. Stability of carotid plaque specimens was assessed by two gold standard histological classifications. Stable and unstable plaques were immunostained for chemerin, chemerin’s receptor (ChemR23), and resistin. Digital and semi-quantifications assessed the % area of expression as well as staining intensity (mild to high) and % of positively stained macrophages/foam cells. Plaque mRNA expression was assessed by quantitative PCR. Sex-hormone analyses are ongoing. Results: Men (n=171) had more unstable plaque features, i.e., greater hemorrhage (P=0.022), lipid core size (P<0.001), inflammation (P=0.007), cap infiltration (P=0.006), and less fibrous tissue (P<0.001) than women (n=79). Circulating chemerin and resistin levels were similar between men and women and no sex differences were observed in relation to plaque instability. The % area of chemerin and resistin staining in the plaque was greater in unstable vs stable plaques in men only (P=0.040; P=0.005, respectively). Similarly, greater intensity in chemerin, ChemR23, and resistin staining was associated with plaque instability in men only (P<0.001; P=0.013; P=0.033, respectively). In contrast, lower resistin plaque mRNA expression was associated with plaque instability in women only (P=0.040). Conclusion: Our results suggest the possibility of a sex-dependent regulatory mechanism underlying the connection between these adipokines and plaque instability.

Background and Aim: Arterial wall shear strain (WSS) has been proposed to impact the features of atherosclerotic plaques. The aim of this meta-analysis was to assess the impact of different types of WSS on plaque features in coronary artery disease (CAD). Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar, and the Cochrane Central Registry, from 1989 up to January 2020 and selected clinical trials and observational studies which assessed the relationship between WSS, measured by intravascular ultrasound (IVUS), and plaque morphology in patients with CAD. Results: In four studies, a total of 72 patients with 13,098 coronary artery segments were recruited, with mean age 57.5 ± 9.5 years. The pooled analysis showed that low WSS was associated with larger baseline lumen area (WMD 2.55 [1.34 to 3.76, p < 0.001]), smaller plaque area (WMD −1.16 [−1.84 to −0.49, p = 0.0007]), lower plaque burden (WMD −12.7 [−21.4 to −4.01, p = 0.04]), and lower necrotic core area (WMD −0.32 [−0.78 to 0.14, p = 0.04]). Low WSS also had smaller fibrous area (WMD −0.79 [−1.88 to 0.30, p = 0.02]) and smaller fibro-fatty area (WMD −0.22 [−0.57 to 0.13, p = 0.02]), compared with high WSS, but the dense calcium score was similar between the two groups (WMD −0.17 [−0.47 to 0.13, p = 0.26]). No differences were found between intermediate and high WSS. Conclusions: High WSS is associated with signs of plaque instability such as higher necrotic core, higher calcium score, and higher plaque burden compared with low WSS. These findings highlight the role of IVUS in assessing plaque vulnerability.

Abstract Background Cerebral oximetry has been widely used to measure regional oxygen saturation in brain tissue, especially during cardiac surgery. Despite its popularity, there have been inconsistent results on the use of cerebral oximetry during cardiac surgery, and few studies have evaluated cerebral oximetry during off pump coronary artery bypass graft surgery (OPCAB). Methods To evaluate the relationship between intraoperative cerebral oximetry and postoperative delirium in patients who underwent OPCAB, we included 1439 patients who underwent OPCAB between October 2004 and December 2016 and among them, 815 patients with sufficient data on regional cerebral oxygen saturation (rSO2) were enrolled in this study. We retrospectively analyzed perioperative variables and the reduction in rSO2 below cut-off values of 75, 70, 65, 60, 55, 50, 45, 40, and 35%. Furthermore, we evaluated the relationship between the reduction in rSO2 and postoperative delirium. Results Delirium occurred in 105 of 815 patients. In both univariable and multivariable analyses, the duration of rSO2 reduction was significantly longer in patients with delirium at cut-offs of < 50 and 45% (for every 5 min, adjusted odds ratio (OR) 1.007 [95% Confidence interval (CI) 1.001 to 1.014] and adjusted OR 1.012 [1.003 to 1.021]; p = 0.024 and 0.011, respectively). The proportion of patients with a rSO2 reduction < 45% was significantly higher among those with delirium (adjusted OR 1.737[1.064 to 2.836], p = 0.027). Conclusions In patients undergoing OPCAB, intraoperative rSO2 reduction was associated with postoperative delirium. Duration of rSO2 less than 50% was 40% longer in the patients with postoperative delirium. The cut-off value of intraoperative rSO2 that associated with postoperative delirium was 50% for the total patient population and 55% for the patients younger than 68 years.

A patient of ischemic heart disease (IHD) with additional carotid artery stenosis (CAS) has been distinguished as a high risk group for both heart and cerebral inconveniences following surgical intervention. We aimed to review the outcome of concurrent carotid endarterectomy (CEA) and off-pump coronary bypass graft (OPCABG)in a patient undergoing surgical revascularization for IHD and CAS at our institute.In the vicinity of 2014 and 2016, fifteen patients experienced OPCABG and CEA associatively in a single Surgeon's Practice. Six (40%) patients had a history of myocardial infarction (MI), four (26.66%) had unstable angina (USAP), and three (20%) had USAP together with MI, though two (13.33%) were asymptomatic. Nine (60%) patients demonstrated no neurological manifestations, three (20%) had transient ischemic assaults (TIAs), two (13.33%) experienced stroke, and 1 (6.66%) experienced both. Majority 7 (46.66%) patients had 75-90% carotid artery stenosis and 6(40%) patients experienced right though 8 (53.33%) experienced left CEA and only 1 (6.66%) had bilateral CEA. Five (33.33%) patients were found left main disease (>50% lesion) and 100% patients have had significant Left Anterior Descending (LAD) lesion in this study. Twelve (80%) patients show significant lesion in Right Coronary Artery (RCA) and ten (66.66%) patients had Obtuse marginal (OM) branch disease. CEA was performed before OPCABG in all cases. There were 15 patients (mean age 62.5±2.8 years; 80% were male), two (13.33%) had a perioperative stroke while one of them had TIAs (6.6%). Mean ICU stay was 36.6±4.5 h and patients were released in 10 days. There was no mortality in the early postoperative period and co-morbidity was less significant (6.6% myocardial ischemia, 13.33% atrial fibrillation, 6.66% TIA, 13.33% Stroke). There was 1 (6.66%) postoperative acute renal failure evidenced by raised serum creatinine level. Two (13.33%) patients showed respiratory complications; only 6.6% of them suffered from wound infection. A combined strategy by means of CEA with OPCABG is safe and savvy in view of the satisfactory consequences of morbidity and mortality rates and also short ICU and hospital stay status.Faridpur Med.
