Imbalance between pro- and anti-inflammatory cytokines secreted from visceral adipose tissue (VAT) contributes to the pathogenesis of certain cardiovascular and metabolic disorders, including insulin resistance. Epicardial adipose tissue (EAT) is a form of VAT mainly concentrated along the coronary arteries. It has been shown in various studies that EAT thickness is positively correlated with cardiovascular disease. Due to its high worldwide prevalence, prevention and management of type 2 diabetes (T2D) has become a major public health challenge. Metformin, the most widely prescribed drug to treat T2D, has favorable effects on VAT and body weight. As metformin decreases VAT mass, in this prospective study we analyzed the possible positive effect of metformin on EAT mass, which is organ-specific VAT, and body mass index (BMI). Subjects were selected from patients admitted to the internal medicine outpatient clinic. Newly diagnosed T2D patients treated with metformin monotherapy were analyzed and 40 patients were included. EAT thickness in the included patients was measured echocardiographically. BMI and EAT thickness were analyzed at the beginning (BMI0 and EAT0) and after three months of metformin monotherapy (BMI3 and EAT3). There was a statistically significant decrease in EAT thickness after three months of metformin monotherapy (EAT0=5.07±1.33 mm vs. EAT3=4.76±1.32 mm; p<0.001). Furthermore, BMI was also significantly decreased (BMI0=28.27±2.71 vs. BMI3=27.29±2.10; p<0.0001). In this study we show that metformin monotherapy significantly decreases EAT thickness and BMI in T2D patients. This suggests that metformin could reduce the frequency of coronary atherosclerosis.
The neutrophil to lymphocyte ratio (NLR) predicts adverse clinical outcomes in several cardiovascular diseases. Our aim was to investigate the association of residual SYNTAX score (rSS) with the NLR in patients (n = 613) with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. Patients were divided into 2 groups: group 1 with low NLR (2.59). Coronary artery disease severity was calculated for both groups besides baseline clinical and demographic variables. Receiver operating characteristic curve analysis demonstrated that NLR with a cutoff value of 2.59 had good predictive value for increased rSS (area under the curve = 0.707, 95% CI: 0.661-0.752, P < .001). The median rSS value of group 2 was higher (2.0 [0-6.0]; 4.0 [0-10.0], P < .001) compared with group 1; the number of patients with high rSS was also higher in group 2 (26 [9.7%]; 107 [31.0%], P < .001). In multivariate logistic regression analysis, the NLR (odds ratio = 3.933; 95% CI: 2.419-6.393; P < .001) was an independent predictor of high rSS. Additionally, there was a positive correlation between NLR and rSS (r = 0.216, P < .001). In conclusion, higher NLR was an independent predictor of increased rSS in patients with STEMI.
Background: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large‐scale study aimed to retrospectively evaluate the long‐term outcomes of the patients who underwent reoperation or TC of PVLs. Methods and Results: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in‐hospital or long‐term outcomes were assessed. The primary end point was defined as the all‐cause death during follow‐up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P =0.549) and procedural success (73.7 versus 65.2%; P =0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in‐hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75–5.88]; P =0.001; and adjusted odds ratio (inverse probability‐weighted), 4.55 [95% CI, 2.27–10.0]; P <0.001). However, the long‐term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59–1.25]; P =0.435; and adjusted HR (inverse probability‐weighted), 1.11 [95% CI, 0.67–1.81]; P =0.679). Conclusions: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long‐term mortality rates compared with surgery.
The present study aimed to compare long-term outcomes of patients with Medina 0.1.0 left main (LM) bifurcation lesions treated by crossover stenting (COS) versus accurate ostial stenting (AOS). A total of 229 consecutive eligible patients with Medina 0.1.0 LM bifurcation lesions were enrolled and were stratified according to the stenting techniques. The primary end-point was major cardiovascular and cerebral events (MACCE), defined as the combination of all-cause death, target vessel related-myocardial infarction (MI), clinically driven target lesion revascularization (TLR), stroke, or stent thrombosis. COS and AOS were applied to 78 (34%) and 151 (66%) patients, respectively. During a mean of 40.6 ± 21.1 months of follow-up, the rate of MACCE (27.8 vs 12.8%; P =.007) was higher in patients treated with AOS than those treated with the COS technique, mainly driven by more frequent all-cause death (13.9 vs 3.8%, P = .013) and TLR (6.4 vs 15.9%; P = .029). In multivariable Cox regression analysis, AOS strategy was one of the independent predictors of MACCE (odds ratio: 2.166; 95% confidence interval, 1.080–4.340; P = .029). The current study suggests that COS was associated with a better long-term MACCE rate and lower all-cause mortality rate than AOS in patients with Medina 0.1.0 LM bifurcation disease.
