Systemic immune inflammation index and its implication on in-stent restenosis among patients with acute coronary syndrome.

OBJECTIVE: This study aims to assess the predictive value of the Systemic Immune Inflammation Index (SII) in determining in-stent restenosis (ISR) likelihood in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI). METHODS: The study enrolled 903 ACS patients undergoing PCI, categorized into ISR (+) and ISR (-) groups based on control coronary angiography results. Demographic, clinical, laboratory, and angiographic-procedural characteristics were systematically compared. RESULTS: The ISR (+) group encompassed 264 individuals (29.2%), while the ISR (-) group comprised 639 individuals (70.8%). Patients had a mean age of 55.8 ±â€…10.2 years, with 69% being male. The ISR (+) group had higher diabetes and smoking prevalence and notably larger stent dimensions. Lab parameters showed significantly elevated creatinine, total cholesterol, red cell distribution width, white blood cell and neutrophil counts, SII index and C-reactive protein (CRP) in the ISR (+) group, while lymphocyte levels were lower. Binary logistic regression identified stent diameter (odds ratio [OR]: 0.598, 95% confidence interval [CI]: 0.383-0.935; P  = 0.024), stent length (OR: 1.166, 95% CI: 1.132-1.200; P  < 0.001), creatinine (OR: 0.366, 95% CI: 0.166-0.771; P  = 0.003), CRP (OR: 1.075, 95% CI: 1.042-1.110; P  = 0.031), and SII index (OR: 1.014, 95% CI: 1.001-1.023; P  < 0.001) as independent ISR predictors. CONCLUSION: The SII index exhibits potential as a predictive marker for ISR in ACS patients post-PCI, indicating systemic inflammation and heightened restenosis risk. Integrating the SII index into risk models could identify high-risk patients for targeted interventions.

The importance of mass diameter in decision-making for preoperative coronary angiography in myxoma patients.

OBJECTIVES: Although coronary angiography (CAG) is generally performed to rule out coexisting coronary artery disease in patients with cardiac myxoma, its necessity to evaluate vascular supply of the myxoma is debatable. The aim of this article is to evaluate clinical experience and CAG findings in our patient group. METHODS: This retrospective analysis was performed in 46 patients (17 men, mean age 57.7 ± 8.6 years), who underwent surgery with an indication for cardiac myxoma between 2004 and 2016 with a CAG performed preoperatively. All CAGs were evaluated in a blinded manner by a cardiac surgeon and a cardiologist separately. Correlations between the presence and pattern of feeding vessels, presence of an arteriocavity fistula (ACF), coronary arterial dominance, size of mass and clinical presentations were analysed. RESULTS: Coronary artery disease defined as >50% obstructive lesions was detected in 10 patients (21.7%). The tumour diameter was found to be significantly higher in patients who had an ACF and a dual-feeding artery (P = 0.049 and P = 0.0001, respectively). Additionally, there was a significant relationship between the presence of dual-feeding vessels and ACF (P = 0.014). ROC analysis revealed a cut-off point of 27 mm in diameter based on the presence of an ACF and a dual-feeding artery. In cases with a diameter of 27 mm or above, the risk of existence of an ACF was 4.68-fold greater, with a confidence interval of 95%, and a dual-feeding pattern was seen in all of them. CONCLUSIONS: This study suggests that preoperative CAG can be considered to detect feeding vessels that may lead to a steal phenomenon, which may alter the management in patients with myxoma greater than 27 mm in diameter.

The effects of weight loss after sleeve gastrectomy on left ventricular systolic function in men versus women.

PURPOSE: To evaluate and compare the effects of weight lost after sleeve gastrectomy on left ventricular (LV) systolic function using both two-dimensional speckle tracking (2D-STE) and three-dimensional echocardiography (3DE) in men versus women. METHODS: In 53 obese patients referred for sleeve gastrectomy, 2D-STE and 3DE were performed prior to and 6 months after surgery. RESULTS: The study included 53 obese patients (62.3% female; mean age 36.8 ± 10.7 years). Six months after surgery, all patients demonstrated a significant decrease in body mass index, body weight, blood pressure, heart rate, LV end-diastolic dimension, myocardial wall thickness, LV mass, LV mass index, LV mass/height(2.7) , LV end-diastolic volume, LV end-systolic volume, and stroke volume as well as an increase in SV index and ejection fraction. There was no significant difference in measured variables between men and women at baseline or postsurgery, except for baseline LV end-diastolic dimension, and baseline and after surgery LV mass, LV mass index, and LV mass/height(2.7) , which were all significantly higher in men. CONCLUSIONS: Sleeve gastrectomy improves LV systolic function and contributes to reverse LV remodeling in both genders. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:492-499, 2016.
