Recently, angiotensin receptor neprilysin inhibitor (ARNi) has emerged as a promising treatment for HF with reduced ejection fraction (HFrEF). Here, we shared our experience with the use of ARNi in HFrEF from multiple centers in Turkey. Methods: The ARNi-TR is a multicenter, nonintervention al, retrospective, observational study. Overall, 779 patients with HF from 22 centers in Turkey who were prescribed sacubitril/valsartan were examined. Initial clinical status, biochemical and echocardiographic parameters, and New York Heart Association functional class (NYHA-FC) values were compared with follow-up values after 1 year of ARNi use. In addition, the effect of ARNi on number of annual hospitalizations was investigated, and the patients were divided into 2 groups, depending on whether ARNi was initiated at hospitalization or under outpatient clinic control. Results: N-terminal pro-brain natriuretic peptide (NT-proBNP), left-ventricle ejection fraction (LV-EF), and NYHA-FC values improved significantly in both groups (all parameters, p<0.001) within 1-year follow-up. In both groups, a decrease in hemoglobin A1c (HbA1c) values was observed in ARNi use (p<0.001), and a decrease in daily diuretic doses and hospitalizations owing to HF were observed after ARNi use (all comparisons, p<0.001). Hypotension (16.9%) was the most common side effect in patients using ARNi. Conclusion: The ARNi-TR study offers comprehensive real-life data for patients using ARNi in Turkey. The use of ARNi has shown significant improvements in FC, NT-proBNP, HbA1c levels, and LV-EF. Likewise, reductions in the number of annual hospitalizations and daily furosemide doses for HF were seen in this study.Item Admission Tpe interval predicts reperfusion success in STEMI patients treated with fibrinolytic agents(2020) Coner, Ali; Akinci, Sinan; Akkucuk, Mehmet Husamettin; Altin, Cihan; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0003-4569-1143; 0000-0001-5250-5404; 31974326; AAG-8233-2020; AAJ-2828-2021; AAD-5564-2021Objective: Myocardial infarction is a leading cause of morbidity and mortality. Fibrinolytic administration is still a life-saving choice in ST-segment elevated myocardial infarction (STEMI), but the rate of successful reperfusion can be inconsistent. Failed reperfusion adds additional clinical risks to rescue percutaneous coronary intervention for STEMI patients. The interval between the peak of the T wave and the end of the T wave (Tpe) and the ratio of Tpe and a corrected measurement of the time from the start of the Q wave to the end of the T wave (Tpe/QTc ratio) are relatively new electrocardiogram (ECG) indices and have not yet been tested in STEMI patients treated with fibrinolytic agents. Methods: A total of 177 STEMI patients (mean age: 60.5 +/- 11.1 years; 138 men and 39 women) were enrolled in this retrospective study to evaluate ECG parameters. The Tpe interval and the Tpe/QTc ratio at baseline and at the 90th minute following the administration of fibrinolytic therapy were analyzed. The clinical and ECG findings of successful and failed reperfusion groups were compared. Results: Successful reperfusion was achieved in 119 patients (67.2%). The average Tpe interval on the admission ECG was shorter (91.7 vs. 100.9 milliseconds [ms]) (p<0.001) and shortened more in the successful reperfusion group (9.3 vs. 4.5 ms) (p<0.001). A cut-off value of 89.0 ms for the Tpe interval on the admission ECG was found to be related to reperfusion success with a sensitivity of 90.9%. Conclusion: The Tpe interval was a predictor for reperfusion success in STEMI patients treated with fibrinolytic agents.Item Clinical characteristics and in-hospital outcomes of acute decompensated heart failure patients with and without atrial fibrillation(2020) Kocabas, Umut; Sinan, Umit Yasar; Arugaslan, Emre; Kursun, Mustafa; Coner, Ali; Celebi, Ozlem Ozcan; Ozturk, Cengiz; Dalgic, Onur; Turkoglu, Ebru Ipek; Kemal, Hatice Soner; Gazi, Emine; Altin, Cihan; Zoghi, Mehdi; 32352420Objective: Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases. The impact of AF on in-hospital outcomes in acute decompensated heart failure (ADHF) is controversial. The aim of this study is to determine the prevalence of AF among hospitalized patients with ADHF and describe the clinical characteristics and in-hospital outcomes of these patients with and without AF. Methods: We examined the multicenter, observational data from the real-life data of hospitalized patients with HF: Journey HF-TR study in Turkey that studied the clinical characteristics and in-hospital outcomes of hospitalized patients with ADHF between September 2015 and September 2016. Results: Of the 1,606 patients hospitalized with ADHF, 626 (39%) had a history of AF or developed new-onset AF during hospitalization. The patients with AF were older (71 +/- 12 vs. 65 +/- 13 years; p<0.001) and more likely to have a history of hypertension, valvular heart disease, and stroke. The AF patients were less likely to have coronary artery disease and diabetes. In-hospital adverse event rates and length of in-hospital stay were similar in ADHF patients, both with and without AF. In-hospital all-cause mortality rate was higher in patients with AF than in patients without AF, although the difference was not statistically significant (8.9% vs. 6.8%; p=0.121). Conclusion: AF has been found in more than one-third of the patients hospitalized with ADHF, and it has varied clinical features and comorbidities. The presence of AF is not associated with increased adverse events or all-cause mortality during the hospitalization time.Item Subclinical myocardial dysfunction in liver transplant candidates determined using speckle-tracking imaging(2019) Inci, Saadet Demirtas; Sade, Leyla Elif; Altin, Cihan; Pirat, Bahar; Pamukcu, Hilal Erken; Yilmaz, Sabriye; Muderrisoglu, Haldun; 31802775Objective: There are various cardiovascular abnormalities in end-stage liver disease (ESLD). In these patients, left ventricular (LV) systolic function is normal at rest but deteriorates during stress. This deterioration may be due to subclinical myocardial dysfunction. This study evaluated global LV and right ventricular (RV) functions using 2-dimensional (2D) speckle tracking in patients with ESLD. Methods: Forty liver transplant candidates with ESLD and 26 healthy individuals were included in the study. All of the patients underwent conventional echocardiographic measurement. Longitudinal, circumferential, and radial strain measurements, as well as apical and parasternal short-axis image recordings were obtained. All 2D strain measurements were measured with offline analysis using velocity vector imaging (VVI) software. Results: In the apical 4- and 2-chamber measurements, the LV mean longitudinal strain was significantly lower in the patient group compared with that of the control group (-16.0 +/- 3.2% versus -17.6 +/- 2.2%, -16.7 +/- 3.3% versus -18.7 +/- 2.1 +/- 2.1 %; p=0.002, respectively). The LV mean circumferential strain did not differ between groups. The LV mean radial strain and RV longitudinal strain were significantly lower in the patient group (45.4 +/- 10.7 vs. 52.7 +/- 10.8%; p=0.01 and -19.2 +/- 3.5% versus -21.5 +/- 3.6%; p=0.03, respectively). Conclusions: Subclinical impairment of global LV and RV systolic functions was determined in liver transplantation candidates using VVI. This deterioration was detected in longitudinal and radial deformation rather than circumferential deformation mechanics, which is consistent with early-stage LV myocardial dysfunction.Item A rare cause of circulatory shock(2014) Altin, Cihan; İzmir, Arzu; Osmanoglu, Sevda; Gezmis, Esin; Sagduyu, Afsin; 25233504Item A clinical dilemma about a new oral anticoagulant treatment(2014) Altin, Cihan; Ozturkeri, Ovgu Anil; Gezmis, Esin; Muderrisoglu, Haldun; 25341482Item A novel oral anticoagulant, dabigatran, in acute renal infarction(2015) Altin, Cihan; Sakallioglu, Onur; Gezmis, Esin; Muderrisoglu, Haldun; 25625445Item Possible renoprotective effects of dabigatran Reply(2015) Altin, Cihan; Sakallioglu, Onur; Gezmis, Esin; Muderrisoglu, Haldun; 26258187Item Coronary anatomy, anatomic variations and anomalies: a retrospective coronary angiography study(2015) Altin, Cihan; Kanyilmaz, Suleyman; Koc, Sahbender; Gursoy, Yusuf Cemil; Bal, Ugur; Aydinalp, Alp; Yildirir, Aylin; Muderrisoglu, Haldun; 25502334INTRODUCTION The incidence of coronary artery anomalies (CAAs) varies from 0.2% to 8.4%. Knowledge of such anatomical variations is important as coronary procedures are regularly performed these days. We aimed to find the coronary dominance pattern, intermediate artery (IMA) frequency and CAA incidence in our clinic, and compare them to those in the literature. METHODS The medical reports of 5,548 patients who had undergone coronary angiography (CAG) between 2005 and 2009 were retrospectively investigated. Dominance pattern and presence of IMA and CAA were recorded. CAAs were described using two different classifications: Angelini and Khatami's classification, and a new modified classification that was derived from Angelini and Khatami's classification. Some procedural details and clinical features of the patients with CAA were also investigated. RESULTS Coronary dominance pattern was: 81.6% right coronary artery, 12.2% circumflex artery and 6.2% co-dominant. IMA was present in 613 (11.0%) patients. The incidences of overall anomaly were 2.7% and 1.4%, according to the different classifications. Absent left main coronary artery, which was the most common anomaly in the present study, was found in 51 (0.9%) patients. Incidences of myocardial bridge, coronary arteriovenous fistulae and aneurysms were 1.1%, 0.2% and 0.3%, respectively. CONCLUSION CAAs are generally asymptomatic, isolated lesions. Some may lead to anginal symptoms, myocardial infarction or sudden death. We found that CAA was associated with increased radiation and contrast exposure in patients who underwent CAG. This risk could be reduced if appropriate catheters were designed and training programmes on ostial cannulation were developed.Item Is echocardiographic epicardial adipose tissue thickness measurement a reliable and reproducible method for risk stratification?(2015) Altin, Cihan; Yilmaz, Mustafa; Gezmis, Esin; 26424627
