Diabetes mellitus (DM) is considered a risk factor for the development of coronary artery disease (CAD). Metformin, an anti-diabetic drug, has been shown to lower the cardiovascular events in pre-clinical and clinical studies. Many research articles suggests that metformin has a protective effect on CAD beyond its hypoglycemic effects. Patients with diabetes type 2 have an increased risk for cardiovascular disease and commonly use combination therapy consisting of the anti-diabetic drug metformin and a cholesterol-lowering statin. Statins have been found to be a safe and effective approach to reduce serum low density lipoprotein cholesterol (LDL-C) levels, which is the cornerstone for primary and secondary prevention of atherosclerosis. However, regular statin monotherapy in some patients may not be sufficient to achieve a therapeutic LDL-C. It has been reported that statins increased the incidence of new-onset diabetes in a dose dependent manner especially in women, the elderly, or in the presence of a family history of type 2 diabetes (T2D) and Asian ethnicity. The molecular mechanisms contributed to antioxidation, anti-inflammation, and anti-apoptosis. In this chapter, we aimed to investigate whether the combined administration of metformin and atorvastatin could achieve superior protective effects on different disease treatment purpose and to elucidate its molecular mechanisms of the combinations.

Atherosclerotic disease is still one of the leading causes of mortality. Atherosclerosis is a complex progressive and systematic artery disease that involves the intima of the large and middle artery vessels. The inflammation has a key role in the pathophysiological process of the disease and the infiltration of the intima from monocytes, macrophages and T-lymphocytes combined with endothelial dysfunction and accumulated oxidized low-density lipoprotein (LDL) are the main findings of atherogenesis. The development of atherosclerosis involves multiple genetic and environmental factors. Although a large number of genes, genetic polymorphisms, and susceptible loci have been identified in chromosomal regions associated with atherosclerosis, it is the epigenetic process that regulates the chromosomal organization and genetic expression that plays a critical role in the pathogenesis of atherosclerosis. Despite the positive progress made in understanding the pathogenesis of atherosclerosis, the knowledge about the disease remains scarce.

Abstract Background There is evidence of statin benefit among patients with diabetes regardless of their cholesterol levels or prior cardiovascular disease history. Despite the evidence, there is under-prescription of statins in clinical practice. This study aimed to assess statin prescriptions and associated factors among patients with type 2 diabetes in Botswana. Methods The study was a secondary data analysis of 374 randomly selected type 2 diabetes patients at a specialised diabetes clinic at Gaborone Botswana. We assessed the proportion of statin-eligible patients who are prescribed statins and evaluated the adjusted associations between various factors and statin prescription. Results Overall, 356 (95.2%) participants were eligible for a statin prescription. Clinicians prescribed statins in 162 (45.5%%; 95% confidence interval [CI]: 40.4% - 50.7%)) of eligible participants, and only one (5.5%) ineligible participant. The probability of statin prescription was high in participants with high baseline low-density lipoprotein cholesterol (risk ratio [RR]: 1.49; 95%CI: 1.17 - 1.89), increasing duration of diabetes (RR: 1.01; 95%CI 1.00 - 1.03) and the presence of chronic kidney disease (RR: 1.35; 95%CI: 1.06 - 1.74). Conclusion Most patients with type 2 diabetes are not receiving statins. Clinicians did not consider most guideline-recommended indications for statin prescription. The findings call for improvement in diabetes quality of care by implementing evidence-based guideline recommendations. Key words: statin, type 2 diabetes mellitus, prescription and Botswana

Objective: Variability in lipid levels has been associated with poor cardiovascular outcomes in patients with coronary artery disease. The aim of this study was to investigate whether low-density lipoprotein cholesterol (LDLC) variability can be used to predict cardiovascular events in patients with type 2 diabetes mellitus (DM). Methods: A total of 5,354 patients with type 2 DM were enrolled in this study. Cardiovascular events including peripheral arterial disease, coronary artery disease, stroke, and cardiovascular death were defined as the study endpoints, and standard deviations of lipid levels were used to define intra-individual lipid variability. Results: Univariate Cox proportional hazards analysis showed that LDL-C standard deviation (hazard ratio [HR] = 1.016; 95% confidence interval [CI] = 1.006 to 1.022; P<.001) was associated with a higher risk of cardiovascular events. Multivariate Cox proportional hazards analysis showed that an increase in LDL-C standard deviation significantly increased the risk of cardiovascular events (HR = 1.063; 95% CI = 1.025 to 1.102; P = .01). Kaplan-Meier analysis of cardiovascular event-free survival showed that the patients in tertiles 2 and 3 of the standard deviation of LDL-C had worse cardiovascular event-free survival compared to those in tertile 1. Conclusion: Variability in LDL-C could predict cardiovascular events in the patients with type 2 DM in this study.

Introduction: Atherosclerotic Coronary Artery Disease (CAD) is fundamentally related to disorders of lipid metabolism. Health problems like obesity, glucose intolerance and metabolic syndrome increase atherosclerotic CAD risk.  A fraction of Low density lipoprotein cholesterol (LDL) is called small dense low density lipoprotein cholesterol (sdLDL). These particles are more atherogenic because they are taken up more easily by arterial wall, readily oxidized and not easily cleared from plasma. Every LDL particle contain an Apo B molecule.Methods: In this cross sectional study we recruited 100 known cases each of CAD, type 2 diabetes, overweight and 100 age and sex matched healthy controls. We took a detailed case summary along with anthropometric measurements. We measured sdLDL by heparin magnesium precipitation method followed by direct estimation of the LDL in the supernatant.Result: Linear regressive analysis showed positive correlation between sdLDL and Apolipoprotein B (Apo B) with LDL cholesterol (r=0.61, p=0.004), (r=0.754, p=0.0034) respectively. Multiple Comparisons after Kruskalwallis test of sdLDL and Apo B levels of  type 2 diabetes, CAD and overweight with controls were significant (p<0.001).Conclusion: Our findings suggest that the estimation of sdLDL and Apo B provide a complimentary benefit in assessment of cases with CAD, type 2 diabetes and overweight.

Abstract Background: Diabetes often accompanies with increase in triglyceride(TG) as well as small dense low density lipoprotein(sdLDL). Statins are difficult to completely correct this dyslipidemia. Xuezhikang, an extract of cholestin, is better than some statins in reducing TG. Under the condition of the similar decrease in LDL-cholesterol (LDL-C), it is not clear whether there is any difference in the effect of XZK and statins on TG reduction in patients with Type 2 DM(T2DM). Methods: An open-label multicenter study is planned to estimate the effects of Xuezhikang(1.2 g/d) and pravastatin(20 mg/d) on TG level and other blood lipids in T2DM patients with dyslipidemia and moderate to high risk of cardiovascular diseases. A total of 114 patients will be enrolled and randomly assigned (1:1 ratio) to accept Xuezhikang or pravastatin therapy for 6 weeks. The primary outcome measure is the change in fasting TG level after 6 weeks. The changes in other fasting lipids and postprandial lipids at 1, 2, 4 h after a nutritious breakfast will also be explored. The planned duration for enrollment is between November 2021 and December 2022. Conclusion: This study will evaluate the effect of 6-week treatment of Xuezhikang(1.2 g/d) and pravastatin(20 mg/d) on fasting TG level and other blood lipids in T2DM patients with dyslipidemia, which may provide a more optimized schedule for lipid control in patients with diabetes and dyslipidemia in primary prevention.

BackgroundPathophysiological vascular remodeling in response to disturbed flow with low and oscillatory shear stress (OSS) plays important roles in atherosclerosis progression. Pomegranate extraction (PE) was reported having anti-atherogenic effects. However, whether it can exert a beneficial effect against disturbed flow-induced pathophysiological vascular remodeling to inhibit atherosclerosis remains unclear. The present study aims at investigating the anti-atherogenic effects of pomegranate peel polyphenols (PPP) extraction and its purified compound punicalagin (PU), as well as their protective effects on disturbed flow-induced vascular dysfunction and their underlying molecular mechanisms.MethodsThe anti-atherogenic effects of PPP/PU were examined on low-density lipoprotein receptor knockout mice fed with a high fat diet. The vaso-protective effects of PPP/PU were examined in rat aortas using myograph assay. A combination of in vivo experiments on rats and in vitro flow system with human endothelial cells (ECs) was used to investigate the pharmacological actions of PPP/PU on EC dysfunction induced by disturbed flow. In addition, the effects of PPP/PU on vascular smooth muscle cell (VSMC) dysfunction were also examined.ResultsPU is the effective component in PPP against atherosclerosis. PPP/PU evoked endothelium-dependent relaxation in rat aortas. PPP/PU inhibited the activation of Smad1/5 in the EC layers at post-stenotic regions of rat aortas exposed to disturbed flow with OSS. PPP/PU suppressed OSS-induced expression of cell cycle regulatory and pro-inflammatory genes in ECs. Moreover, PPP/PU inhibited inflammation-induced VSMC dysfunction.ConclusionPPP/PU protect against OSS-induced vascular remodeling through inhibiting force-specific activation of Smad1/5 in ECs and this mechanism contributes to their anti-atherogenic effects.

Cardiovascular disease is the leading cause of major morbidity and mortality in patients with type 2 diabetes. The recent focus on the apparent lack of cardiovascular benefit associated with glucose-lowering strategies has overshadowed the importance of targeting dyslipidemia for cardiovascular prevention in patients with diabetes. While lowering low-density lipoprotein (LDL) cholesterol is beneficial, diabetes is also characterized by hypertriglyceridemia, low levels of high-density lipoproteHDL-cholesterol and abundant levels of small, dense LDL particles. Accordingly, these factors represent additional targets for therapeutic modification in order to achieve more effective reductions in cardiovascular risk.
