The increase in the life expectancy of the population  is accompanied by an increase in the prevalence of diseases for which old and senile age are risk factors. Atrial fibrillation (AF) and chronic kidney disease (CKD) are two diseases that can coexist in a patient. The risk of ac thromboembolic and hemorrhagic events in this case increases due to the mutual aggravating influence of these diseases. In addition,  these patients have a high incidence of coronary  events, and cardiovascular complications are the main cause of death in patients with AF and CKD. Consequently, such patients require an integrated  approach  to treatment,  and their management is a complex  clinical task. The direct oral anticoagulant rivaroxaban has been most studied in a population  of comorbid  AF and CKD  patients and has proven a high efficacy and safety profile in these patients in randomized controlled trials. In addition,  rivaroxaban has shown  a significant  reduction in the risk of myocardial  infarction  in various patients,  as well as the possibility of preserving renal function to a greater extent compared  with warfarin therapy, and a possible positive effect on reducing  the risk of cognitive impairment.  A single dosing  regimen  can improve adherence  to treatment,  which is one of the key conditions  for achieving  the above effects. Thus, these factors make it possible to achieve comprehensive protection of comorbid  patients with AF and CKD.

Dyslipidemia is a major modifiable risk factor for ischemic stroke. Treatment with statins reduces the incidence of recurrent ischemic stroke and also reduces coronary events in patients with a history of ischemic stroke. Therefore, statins represent an important component of secondary prevention of ischemic stroke. In patients who do not achieve low-density lipoprotein cholesterol (LDL-C) targets despite treatment with the maximal tolerated dose of a potent statin, ezetimibe should be added to their lipid-lowering treatment and also appears to reduce the risk of cardiovascular events. Selected patients who do not achieve LDL-C targets despite statin/ezetimibe combination are candidates for receiving proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors. Finally, it appears that adding icosapent ethyl might also reduce cardiovascular morbidity in patients who have achieved LDL-C targets but have persistently elevated triglyceride levels.

Current risk stratification strategies for coronary artery disease (CAD) have low predictive value in asymptomatic subjects classified as intermediate cardiovascular risk. This is relevant because not all coronary events occur in individuals with traditional multiple risk factors. Most importantly, the first manifestation of the disease may be either sudden cardiac death or acute coronary syndrome, after rupture and thrombosis of an unstable non-obstructive atherosclerotic plaque, which was previously silent. The inaccurate stratification using the current models may ultimately subject the individual to excessive or insufficient preventive therapies. A breakthrough in the comprehension of the molecular mechanisms governing the atherosclerosis pathology has driven many researches toward the necessity for a better risk stratification. In this Review, we discuss how metabolomics screening integrated with traditional risk assessments becomes a powerful approach to improve non-invasive CAD subclinical diagnostics. In addition, this Review highlights the findings of metabolomics studies performed by two relevant analytical platforms in current use–mass spectrometry (MS) hyphenated to separation techniques and nuclear magnetic resonance spectroscopy (NMR) –and evaluates critically the challenges for further clinical implementation of metabolomics data. We also discuss the modern understanding of the pathophysiology of atherosclerosis and the limitations of traditional analytical methods. Our aim is to show how discriminant metabolites originated from metabolomics approaches may become promising candidate molecules to aid intermediate risk patient stratification for cardiovascular events and how these tools could successfully meet the demands to translate cardiovascular metabolic biomarkers into clinical settings.

Reduction in coronary events rates in high-risk patients is feasible by altering cardiovascular risk factors. In the US and most European Countries, the leading cause of death is coronary heart disease (CHD). Hypercholesterolemia is the principal risk factor for coronary artery disease. High-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) are significant risk factors for CHD [1]. Hydroxymethylglutaryl-CoA (HMG-Co-A) inhibitors are the most effective treatment of cutting LDL-C levels with a subsequent reduction in cardiovascular death and morbidity. A nudge happens when a choice architecture is planned to control behaviour predictably without curbing an individual’s choice [2]. For a nudge to be influential, the direction and force should be in line with professional standards. The article detailed how patients' and physicians' actions contributed to the increasing incidence of cardiovascular diseases. Nudges either digital or  manual (use of post-it) can be useful in influencing physicians to be proactive and can increase patients’ adherence to the therapy. Trust between the patient and the physician is crucial in attaining these goals. Nudges can be a valuable management tool for steering correct behaviours among healthcare providers. The technique is to ensure that physicians see them as something constructive and not irritating or controlling noodges.

Abstract Aims Air pollution is an emerging key player in determining the residual risk of coronary events. However, pathophysiological mechanisms linking air pollution and coronary events have been not adequately investigated. We aimed at assessing the relationship between exposure to air pollutants and mechanisms of coronary instability evaluated by optical coherence tomography (OCT) in patients with acute coronary syndrome (ACS). Methods and results ACS patients undergoing OCT imaging were retrospectively selected. Mechanism of culprit lesion instability was classified as plaque rupture (PR) or intact fibrous cap (IFC) by OCT, and the presence of macrophage infiltrates (MØI) and thin-cap fibroatheroma (TCFA) at the culprit site was also assessed. Based on each case’s home address, exposure to several pollutants was evaluated, including particulate matter 2.5 (PM2.5), particulate matter 10 (PM10), and carbon monoxide (CO). Only patients with >2 years of available data on air pollution exposure prior to ACS were enrolled. We included 126 patients [median age 67.0 years (55.5–76.0), 97 (77.0%) male]. Sixty-six patients (52.4%) had PR as mechanism of plaque instability. Patients with PR were exposed to significantly higher PM2.5 levels compared to IFC, and PM2.5 was independently associated with PR [odds ratio per unit = 1.194, 95% CI: (1.036–1.377), P = 0.015]. Moreover, exposure to higher levels of PM2.5 was independently associated with the presence of TCFA and of MØI at the culprit site. Interestingly, PM2.5, PM10, and CO levels were positively and significantly correlated with serum levels of C-reactive protein. ROC curves were constructed to assess the ability of PM2.5 to predict the presence of plaque rupture, TCFA or MØI. The AUC for PM2.5 to predict plaque rupture was 0.62 (95% CI: 0.52–0.71, P = 0.018), for TCFA was 0.71 (95% CI: 0.61–0.80, P <0.001) and for MØI was 0.80 (95% CI: 0.71–0.88, P <0.001). Using a PM2.5 cut-off value of 13.40 μg/m3, the sensitivity and specificity for MØI were 81% and 66%, respectively. Conclusions We provide novel insights into the missing link between air pollution and increased risk of coronary events. In particular, exposure to higher concentrations of air pollutants is a risk factor for vulnerable plaque features and for plaque rupture as mechanism of coronary instability mediated by systemic and local plaque inflammation. Of importance, the thresholds of air pollutants that predicted the presence of vulnerable plaque features are far lower than commonly accepted safety thresholds used to start preventive measures for public health, suggesting that further efforts are needed in order to reduce the adverse effects on the cardiovascular system.

Aim: To find the frequency of recently poor glycemic control as assessed by HbA1c in diabetic patients with acute coronary syndrome Study design & Setting: Observational study. Methods: The study included 60 diabetic patients presented with acute coronary syndrome. Diagnosis of acute coronary syndrome was based on patient’s symptoms, ECG changes and cardiac enzyme results. HBA1c level report was collected for all patients from their hospital record. SPSS 21 version was used to analyze the collected data. The qualitative data was presented in the form of graphs while the quantitative data was presented by simple descriptive statistics in the form of mean, range and standard deviation. Results: Out of sixty patients enrolled in this study 2(45%) were females and 33(55%) were males. 28(46.67%) patients presented with ST-elevation MI (STEMI) whereas 25(41.66%) patients presented with non ST-elevation MI. 7(11.66%) had unstable angina. Out of sixty patients 21(35%) patients were having poor glycemic control (HBA1C >7%) whereas 39(65%) patients had fair glycemic control (HBA1C< 7%). Fifty eight (96%) patients were using oral anti diabetic tablets whereas 2(3.33%) patients were using insulin before hospital admission. Conclusion: This study shows that amongst patients admitted with acute coronary syndrome a significant proportion of patients (35%) had poor glycemic control over past three months as assessed by HBA1C implying that recent poor glycemic control is a significant risk factor for acute coronary events in diabetic patients. Keywords: Acute coronary syndrome, Glycemic control, Diabetes mellitus.

Objective: While the risk of acute coronary events has been associated with biological variability of circulating cholesterol, the association with variability of other atherogenic lipids remains less understood. We evaluated the longitudinal variability of 284 lipids and investigated their association with asymptomatic coronary atherosclerosis. Approach and Results: Circulating lipids were extracted from fasting blood samples of 83 community-sampled symptom-free participants (age 41–75 years), collected longitudinally over 6 months. Three types of coronary plaque volume (calcified, lipid-rich, and fibrotic) were quantified using computed tomography coronary angiogram. We first deconvoluted between-subject (CV g ) and within-subject (CV w ) lipid variabilities. We then tested whether the mean lipid abundance was different across groups categorized by Framingham risk score and plaques phenotypes (lipid-rich, fibrotic, and calcified). Last, we investigated whether visit-to-visit variability of each lipid was associated with plaque burden. Most lipids (72.5%) exhibited higher CV g than CV w . Among the lipids (N=145) with 1.2-fold higher CV g than CV w , 26 species including glycerides and ceramides were significantly associated with Framingham risk score and the 3 plaque phenotypes (false discovery rate <0.05). In an exploratory analysis of person-specific visit-to-visit variability without multiple-comparisons testing, high variability of 3 lysophospholipids (lysophosphatidylcholines 16:0, 18:0, and O-18:1) were associated with lipid-rich and fibrotic (noncalcified) plaque volume while high variability of diacylglycerol 18:1_20:0, triacylglycerols 52:2, 52:3, and 52:4, ceramide d18:0/20:0, dihexosylceramide d18:1/16:0, and sphingomyelin 36:3 were associated with calcified plaque volume. Conclusions: High person-specific longitudinal variation of specific nonsterol lipids are associated with the burden of subclinical coronary atherosclerosis. Larger studies are needed to confirm these exploratory findings.

Abstract Background Although coronary events (CE) and ischemic stroke share many risk factors, there are also some important differences. The aim of this paper was to assess the association of risk factors in relation to incident CE and ischemic stroke and to evaluate the heterogeneity in patterns of risk factors between the two outcomes. Method Traditional risk factors and inflammatory markers associated with coronary events and ischemic stroke were measured in the Malmö Diet and Cancer Cohort (MDCS, n = 26 519), where a total of 2270 incident ischemic stroke and 3087 incident CE occurred during a mean follow up time 19 ± 6 years, and in relation to inflammatory markers in the cardiovascular sub-cohort (MDC-CV, n = 4795). Cox regression analysis was used to obtain hazard ratios. A modified Lunn-McNeil competing risk analysis was conducted to assess the significance of any differences in risk profiles of these outcomes. Results Most cardiovascular risk factors were associated both with incident CE and ischemic stroke. However, current smoking, ApoB, low ApoA1, male sex and education level of ≤ 9 years of schooling were preferentially associated with CE compared to ischemic stroke. Conversely, age showed a stronger association with ischemic stroke than with CE. Conclusion CE and ischemic stroke have broadly similar risk factors profiles. However, there are some important differential associations, as well as substantial differences in the magnitude of the association. These could reflect the distinct biology of atherogenesis in different vascular beds. The difference in the determinants highlights the importance of looking at CE and ischemic stroke, two manifestations of cardiovascular disease, separately.
