(Sage Publications inc, 2024) Oguz, Mustafa; Akbulut, Tayyar; Saylik, Faysal; Sipal, Abdulcabbar; Erdal, Emrah
Coronary in-stent restenosis (ISR) remains a challenge in interventional cardiology. We investigated the relationship between angiographic pre-interventional grade of lesion stenosis (LS) and the prognosis of late ISR. After exclusions, 110 patients with ISR and 109 patients without ISR were compared. In the ISR group, the grade of LS was greater (P < .001) and the length of the critical segment (LCS) was longer (P < .001). Stent length was longer in the ISR group (P = .008). Compared with the LCS, the grade of LS above 87.5% is 6.9 times more predictive of ISR than the LCS >10.5 mm. Kaplan-Meier curve analysis showed that the grade of initial LS >87.5% had a higher ISR rate than the grade of LS <87.5% (log-rank test P < .001) and critical lesion length over 10.5 mm had a higher ISR rate than critical lesion length under 10.5 mm (log-rank test P < .001). The present study found that the angiographic pre-interventional grades of LS and LCS were important predictors of ISR. Pre-interventional angiographic stenosis >87.5% was significantly predictive of late ISR.
Association of Echocardiographic Parameters With Chest Computed Tomography Score in Patients With Covid-19 Disease
(Elsevier Urban & Partner Sp Z O O, 2021) Saylik, Faysal; Akbulut, Tayyar; Oguz, Mustafa; Sipal, Abdulcabbar; Ormeci, Tolgahan
Purpose: Although coronavirus disease 2019 (COVID-19) primarily affects the pulmonary system, the involvement of the heart has become a well-known issue. Pulmonary CT plays an additive role in the diagnosis and prognosis of the disease. We aimed to investigate the association of echocardiographic indices with pulmonary CT scores and mortality in COVID-19 patients. Materials and methods: A total of 123 patients diagnosed with COVID-19 were included in this study. The British Society of Thoracic Imaging (BSTI) score and echocardiographic parameters were calculated, and echocardio-graphic indices were compared between BSTI score grades. Results: During in-hospital follow-up, 36 of 123 patients (29.3%) had died. BSTI score, IVS, LVPWd, RV mid-diameter, RV basal diameter, RV longitudinal diameter, sPAP, and RVMPI were higher, and RVFAC, TAPSE, and RVS were lower in the non-survivor group than in the survivor group. There were statistically significant changes between BSTI scores in terms of LVPWd, RV mid diameter, RV basal diameter, RV longitudinal diameter, sPAP, RVFAC, RVMPI, and TAPSE. BSTI score was positively correlated with sPAP and RV basal diameter and negatively correlated with TAPSE and RVFAC. Multivariate logistic regression analysis demonstrated that sPAP (OR = 1.071, p = 0.002) and RV basal diameter (OR = 1.184, p = 0.005) were independent predictors of high BSTI scores (grade 4 and 5). Furthermore, age, sPAP, and a high BSTI score (grade 5) were independent predictors of in-hospital mortality in COVID-19 patients. Conclusion: Echocardiographic indices were correlated with BSTI scores, and patients with higher BSTI scores had more cardiac involvement in COVID-19.
Fragmented Qrs in Inferior Leads Is Associated With Non-Alcholic Fatty Liver Disease, Body-Mass Index, and Interventricular Septum Thickness in Young Men
(Aves, 2022) Sarikaya, Remzi; Sengul, Cihan; Kumet, Omer; Imre, Gurkan; Akbulut, Tayyar; Oguz, Mustafa
Objective: Fragmented QRS (fQRS) has been shown to be related to coronary heart disease, heart failure, hypertension, cardiac arrhythmia, and metabolic syndrome. Although fQRS in lateral leads is shown to be associated with a poor outcome in patients with a known cardiac disease, the knowledge about the significance and prevalence of fQRS in inferior leads is scarce. This study aimed to investigate the prevalence and predictors of fQRS in inferior leads in healthy young men. Methods: A total of 1,155 men underwent electrocardiography (ECG), hepatic ultrasonography, and routine biochemical tests. A total of 210 eligible men with fQRS in inferior leads (group 1) and 770 eligible men without fQRS in inferior leads (group 2) were compared with each other in terms of clinical, demographic, and laboratory parameters. Results: The prevalence of fQRS in inferior leads was found to 21.4%. Body mass index (BMI), systolic blood pressure (BP), creatinine, and alanine aminotransferase levels; non-alcoholic fatty liver disease (NAFLD) percentage; and interventricular septum thickness (IVST) were significantly greater in group 1 than those in group 2. BMI, IVST, NAFLD, creatinine, ALT, and systolic BP were entered in a model of multiple regression analyses to predict fQRS, a dependent variable. NAFLD was the best independent predictor of fQRS (beta=6.115, p=0.001). BMI (beta=1.448, p=0.014) and IVST (beta=1.058, p=0.029) were the other independent predictors of fQRS in inferior leads. Conclusion: This study demonstrated the association of fQRS in inferior leads with NAFLD, BMI, and IVST in young men.

Thrombus-Demarcated Stenting With Dual-Contrast Imaging: a Novel Approach for Late-St Elevation Myocardial Infarction With Unsuccessful Predilatation
(Thieme Medical Publ inc, 2024) Oguz, Mustafa; Akbulut, Tayyar; Saylik, Faysal; Cinar, Tufan
The success of revascularization in the total occluded coronary lesion with dense thrombus burden is important for the short- and long-term prognosis of patients with acute ST-segment elevation myocardial infarction (STEMI). In these lesions, stenting without dispersing the thrombus can increase the success of revascularization without fatal complications. The aim of this case is to demonstrate the newly developed thrombus-demarcated stenting with dual-contrast imaging approach after unsuccessful predilatation in a late-inferior STEMI. In centers where optical coherence tomography is not available, this technique can be used as an alternative.
