Abstract Background Previous studies have suggested that patients with diabetes mellitus (DM) have higher prevalence of atherosclerotic cardiovascular disease (ASCVD), and plasma levels of free fatty acids (FFAs) are a useful marker for predicting ASCVD. We hypothesized that FFAs could predict both coronary and carotid lesions in an individual with type 2 DM (T2DM). The present study, hence, was to investigate the relation of plasma FFA level to the presence and severity of coronary and carotid atherosclerosis in patients with T2DM. Methods Three hundred and two consecutive individuals with T2DM who have received carotid ultrasonography and coronary angiography due to chest pain were enrolled in this study. Plasma FFAs were measured using an automatic biochemistry analyzer. Coronary and carotid severity was evaluated by Gensini score and Crouse score respectively. Subsequently, the relation of FFA levels to the presence and severity of coronary artery disease (CAD) and carotid atherosclerotic plaque (CAP) in whole individuals were also assessed. Results Increased plasma FFA levels were found in the groups either CAD or CAP compared to those without. Patients with higher level of FFAs had a higher CAD (89.9%) and elevated prevalence of CAP (69.7%). And also, patients with higher level of FFAs had a higher Gensini and Crouse scores. Multivariate regression analysis showed that FFA levels were independently associated with the presence of CAD and CAP (OR = 1.83, 95%CI: 1.27–2.65, P = 0.001; OR = 1.62, 95%CI: 1.22–2.14, P = 0.001, respectively). The area under the curve (AUC) was 0.68 and 0.65 for predicting the presence of CAD and CAP in patients with DM respectively. Conclusions The present study firstly indicated that elevated FFA levels appeared associated with both the presence and severity of CAD and CAP in patients with T2DM, suggesting that plasma FFA levels may be a useful biomarker for improving management of patients with T2DM.

Type 2 diabetes mellitus is a major risk factor for cardiovascular disease and mortality. Uncontrolled type 2 diabetes mellitus results in a systemic milieu of increased circulating glucose and fatty acids. The development of insulin resistance in cardiac tissue decreases cellular glucose import and enhances mitochondrial fatty acid uptake. While triacylglycerol and cytotoxic lipid species begin to accumulate in the cardiomyocyte, the energy substrate utilization ratio of free fatty acids to glucose changes to almost entirely free fatty acids. Accumulating evidence suggests a role of miRNA in mediating this metabolic transition. Energy substrate metabolism, apoptosis, and the production and response to excess reactive oxygen species are regulated by miRNA expression. The current momentum for understanding the dynamics of miRNA expression is limited by a lack of understanding of how miRNA expression is controlled. While miRNAs are important regulators in both normal and pathological states, an additional layer of complexity is added when regulation of miRNA regulators is considered. miRNA expression is known to be regulated through a number of mechanisms, which include, but are not limited to, epigenetics, exosomal transport, processing, and posttranscriptional sequestration. The purpose of this review is to outline how mitochondrial processes are regulated by miRNAs in the diabetic heart. Furthermore, we will highlight the regulatory mechanisms, such as epigenetics, exosomal transport, miRNA processing, and posttranslational sequestration, that participate as regulators of miRNA expression. Additionally, current and future treatment strategies targeting dysfunctional mitochondrial processes in the diseased myocardium, as well as emerging miRNA-based therapies, will be summarized.

The Relationship

Background: Patients with type 2 diabetes mellitus (T2DM) have an elevated risk of atherosclerotic cardiovascular disease. Although previous data have suggested that serum calcium levels could be involved in T2DM and cardiovascular disease, whether this applies in T2DM patients with atherosclerosis remains unclear. This study therefore aimed to investigate the relationship between serum calcium levels within the physiological ranges and carotid atherosclerotic plaque in T2DM patients. Methods: A total of 594 normocalcaemic in-patients with T2DM were recruited, of whom 231 had carotid atherosclerotic plaque. Serum calcium levels were measured and carotid ultrasonography was performed. Results: Patients with plaque had significantly higher serum albumin-corrected calcium than those without plaque [9.02 (8.78–9.34) mg/dL versus 8.86 (8.66–9.06) mg/dL, p < 0.001]. As serum albumin-corrected calcium levels increased across tertiles, the percentage of plaque increased (27.6%, 35.5%, and 55.7%; p < 0.001). Logistic regression showed that serum albumin-corrected calcium levels were independently and positively correlated with the presence of plaque, but not parathyroid hormone levels. Compared with patients in the lowest serum calcium tertiles, the odds ratio for plaque in patients in the upper quartile was 2.47 (95% confidence interval 1.51–4.03, p < 0.001) after adjustment for potential confounders. Conclusion: Serum albumin-corrected calcium levels are elevated in patients with T2DM and carotid atherosclerotic plaques.

Background: Dyslipidaemia is a major risk factor for cardiovascular complications in patients with type 2 diabetes mellitus and affects 10-73% of this population. In type 2 diabetes mellitus, increased efflux of free fatty acids from adipose tissue and impaired insulin mediated skeletal muscle uptake of free fatty acids, increases fatty acid flux to the liver and also decreased glucose utilization in muscle that leads to acute elevation of free fatty acids. Lipid profile which is altered in diabetes state is one of the significant factors in development of cardiovascular diseases. The derangements seen in serum lipid profile includes: increased total cholesterol (TC), triglycerides (TG) and low-density lipoprotein (LDL) and decreased high-density lipoprotein cholesterol (HDL) concentration. Hence with the aforementioned views the present study had been planned to evaluate the effect of atorvastatin and metformin combination therapy in type 2 diabetic dyslipidemias.Methods: Study design, observational prospective study, with duration of 4-5 months and sample size of 30 patients with type 2 diabetes mellitus are taken with mild to moderate dyslipidemias. The study subjects received combination therapy of metformin 500 mg/day along with atorvastatin 20mg/day, there effect is seen on serum lipid profile and fasting blood glucose levels (FBS).Results: There was a significant mean decrease in TC, LDL , TG , FBS by 31.7 mg/dl (p<0.05), 28.5 mg/dl (p value <0.05), 19.5 mg/dl (p<0.05), 9.13 mg/dl (p<0.05) respectively and rise in HDL by 1.7 mg/dl (p<0.05) ), no significant decrease in VLDL (p>0.05).Conclusions: Combination of atorvastatin and metformin was effective in reduction of TC, LDL, TG and FBS and elevation of HDL levels in type-2 diabetic dyslipidemias.

Increase in plasma free fatty acids (FFAs) concentrations may cause cellular damage via the induction of oxidative stress. The aim of this present study was to investigate FFAs and oxidative stress in hypertension co-morbidly occurring with Type 2 Diabetes Mellitus (T2DM). Age and sex matched control subjects (n=150) and patients (n=470) [hypertensive nondiabetics (HND, n=179), normotensive diabetics (ND, n=132), hypertensive diabetics (HD, n=159)] presenting at the Medical Out-Patient Clinic of the State Hospital, Abeokuta, Nigeria were recruited. Fasting plasma glucose, creatinine, urea, FFAs, thiobarbituric acid reactive substances (TBARS) were determined spectrophotometrically. The presence of either or both diseases resulted in significant increase (p<0.05) in the plasma FFAs and oxidative stress marker-TBARS in different compartments (plasma, erythrocytes andlipoproteins) for both male and female patients when compared with their control counterparts. The increase in FFAs was more marked in comorbidity female when compared with other female patients. There was significant (p<0.05) difference in gender FFAs concentrations. In both controls and patients, FFAs in plasma are significantly (p<0.05) higher in male when compared with their female counterparts. This research revealed biochemical variations in hypertension co-morbidly occurring with T2DMcharacterised by gender-related elevation in FFAs and enhanced oxidative stress. Plasma FFAs might be a good biomarker predicting the occurrence and development of hypertension and/or T2DM.
