    Real-World Data on the Incidence of Stroke, Myocardial Infarction, and Mortality Among Nonvalvular Atrial Fibrillation Patients in Türkiye: New Oral Anticoagulants-TURKey Study
    (2023) Unlu, Serkan; Altay, Servet; Gedikli, Omer; Ozden, Ozge; Canpolat, Ugur; Askin, Lutfu; Yayla, Cagri; Yanik, Ahmet; Cakmak, Huseyin Altug; Sinan, Umit Yasar; Besli, Feyzullah; Sahin, Mahmut; Pehlivanoglu, Seckin; 0000-0002-4837-7099; 37888785; A-7003-2017
    Background: Atrial fibrillation (AF) is strongly associated with an increased risk of isch- emic events. Anticoagulation focuses on reducing the risk of embolism. Guideline recom- mended CHA2DS2-VASc scoring system is most widely used; however, different scoring systems do exist. Thus, we sought to assess the impact of anticoagulant treatment and different scoring systems on the development of stroke, myocardial infarction, and allcause mortality in patients with nonvalvular AF. Methods: The present study was designed as a prospective cohort study. The enrollment of the patients was conducted between August 1, 2015, and January 1, 2016. The followup period was defined as the time from enrollment to the end of April 1, 2017, which also provided at least 12 months of prospective follow-up for each patient. Results: A total of 1807 patients with AF were enrolled. During the follow-up, 2.7% (48) of patients had stroke, 0.8% (14) had myocardial infarction, and 7.5% (136) died. The antico- agulation and risk factors in AF (ATRIA) score had a better accuracy for the prediction of stroke compared to other scoring systems (0.729, 95% CI, 0.708-0.750, P < .05). Patients under low -dose rivaroxaban treatment had significantly worse survival (logrankP < .001). Age, CHA2DS2-VASc score, R2CHADS2 score, ATRIA score, chronic heart failure, prior stroke, and being under low -dose rivaroxaban treatment were independent predictors of clinical endpoint (P < .001). Conclusion: Low -dose rivaroxaban treatment was independently and strongly associated with the combined clinical endpoint. Furthermore, the ATRIA score proved to be a stronger predictor of stroke in the Turkish population.

    Effect of acute kidney injury on long-term mortality in patients with ST-segment elevation myocardial infarction complicated by cardiogenic shock who underwent primary percutaneous coronary intervention in a high-volume tertiary center
    (2020) Hayiroglu, Mert Ilker; Bozbeyoglu, Emrah; Yildirimturk, Ozlem; Tekkesin, Ahmet Ilker; Pehlivanoglu, Seckin; 31974325
    Objective: Acute kidney injury (AKI) is a reflection of both renal and cardiac reserve in patients with ST-segment elevation myocardial infarction (STEMI), but there is a lack of evidence related to the effect of AKI on long-term mortality in patients with STEMI. This study was an investigation of the prognostic value of AKI for long-term mortality in patients with STEMI complicated by cardiogenic shock (CS) and primary percutaneous coronary intervention (PPCI). Methods: This retrospective analysis evaluated the long-term prognostic impact of AKI on 492 patients with STEMI complicated by CS who were treated with PPCI. AKI was defined as >= 0.3mg/dL increase in serum creatinine within 48 hours or a >= 50% increase in serum creatinine in 7 days, or a reduction in urine output (documented oliguria of less than 0.5mL/kg per hour >6 hours. Patients were grouped according to the incidence of AKI and long-term mortality was compared. Cox regression analysis was used to determine independent prognostic factors of long-term mortality. Results: In Cox regression analysis, the age- and sex- adjusted hazard ratios (HRs) were higher for all-cause mortality in patients with AKI. [HR: 4.556; 95% confidence interval: (CI) 2.370-8.759]. After adjustment for confounding variables, the relative risk was greater for patients with AKI in comparison with patients without AKI (HR: 2.207; 95% CI: 1.150-4.739). Age (HR: 1.060, 95% CI: 1.027-1.094; p<0.001), left ventricular ejection fraction (HR: 0.952, 95% CI: 0.916-0.989; p=0.012), blood urea nitrogen level (HR: 1.019, 95% CI: 1.005-1.034; p=0.010), and AKI (HR: 2.244, 95% CI: 1.077-4.676; p=0.031) were found to be independent factors to determine long-term mortality. Conclusion: The results of this study demonstrated that AKI was an independent prognostic factor for long-term mortality among patients with STEMI complicated by CS and treated with PPCI.
