Methods: In this prospective, open label study, 48 NSTE-ACS were randomized to niacin or control group. Patients continued their optimal medical therapy in the control group. In the niacin group patients were assigned to receive extended-release niacin 500 mg/day. Patients were contacted 1 month later to assess compliance and side effects. Blood samples for hs-CRP were obtained upon admittance to the coronary care unit, in the third day and in the first month of the treatment. Fasting blood samples for cholesterol levels were obtained before and 30 days after the treatment. The primary end point of the study was to evaluate changes in hs-CRP, cholesterol levels, short-term cardiovascular events, and the safety of niacin in NSTE-ACS. Results: Baseline demographic, clinical and laboratory characteristics were similar between the two groups. Logarithmic transformation of baseline and 3rd day hs-CRP levels were similar between the groups; but 1 month later, logarithmic transformation of hs-CRP level was significantly lower in the niacin group (0.43 +/- 0.39 to 0.83 +/- 0.91, p = 0.04). HDL-C level was significantly increased in the niacin group during follow-up. Drug related side effects were seen in 7 patients in the niacin group but no patients discontinued niacin. Conclusions: Our findings demonstrate that lower dose extended release niacin can be used safely and decreases hs-CRP and lipid parameters successfully in NSTE-ACS patients.Item Chronic Aortic Dissection and Recoarctation As A Late Complication of Aortic Coarctation Surgery(2015) Coner, Ali; Balcioglu, Serhat; Akinci, Sinan; Cicek, Davran; Muderrisoglu, Haldun; 0000-0001-5250-5404; 0000-0002-9635-6313; 0000-0002-5711-8873; 26717344; AAC-8036-2020; AAD-5564-2021; AAG-8233-2020; ABD-7321-2021Item Acquired Aneurysm of Sinus of Valsalva(2017) Coner, Ali; Akinci, Sinan; Cicek, Davran; Saba, Tonguc; Muderrisoglu, Haldun; 0000-0002-9635-6313; 0000-0001-5250-5404; 0000-0002-5711-8873; AAG-8233-2020; AAC-8036-2020; AAD-5564-2021; ABD-7321-2021Item Which Is Responsible for Cardiac Autonomic Dysfunction in Non-Diabetic Patients with Metabolic Syndrome: Prediabetes or the Syndrome Itself(2016) Balcioglu, Akif Serhat; Akinci, Sinan; Cicek, Davran; Eldem, Halil Olcay; Coner, Ali; Bal, Ugur Abbas; Muderrisoglu, Haldun; https://orcid.org/0000-0001-5250-5404; https://orcid.org/0000-0002-5711-8873; https://orcid.org/0000-0002-9446-2518; 26610403; AAD-5564-2021; ABD-7321-2021; AAK-4322-2021Aims: Cardiac autonomic dysfunction (CAD) is associated with both prediabetes and metabolic syndrome (MS). Heart rate variability (HRV) and heart rate turbulence (HRT) are reliable 24-h Holter-ECG findings of cardiac autonomic function. This study aimed to investigate the relation between MS and its components and CAD using HRV and HRT. Materials and methods: The study included 80 non-diabetic patients with MS and 70 control subjects. All study population and the patients with MS were further analyzed for each diagnostic component of MS to investigate which criteria impaired HRV and HRT. Results: HRV and HRT parameters were disturbed in patients in the MS group. While impairment in HRV and HRT was significantly related to the presence of the fasting plasma glucose (FPG) criterion, there were no differences between groups in terms of the other 4 MS criteria. Moreover, FPG level was significantly correlated with SDNN (r = -0.352, p < 0.001), SDNN index (r = -0.423, p < 0.001), SDANN (r = -0.301, p < 0.001), RMSSD (r = -0.237, p < 0.001), pNN50 (r = -0.237, p < 0.001), turbulence onset (TO) (r = 0.365, p < 0.001) and turbulence slope (TS) (r = -0.365, p < 0.001). Among the MS diagnostic criteria, only FPG level was an independent determinant of all HRV and HRT parameters. Conclusions: This study confirms the relation between MS and CAD. Increased FPG alone appears to be responsible for the mentioned findings among the 5 diagnostic criteria. Accordingly, CAD may be the result of prediabetes, not MS in patients with MS.

Methods: Patients who were treated interventionally between 2015 and 2020 and were using tirofiban were retrospectively screened. Clinical, laboratory, and angiographic findings were obtained from the hospital database. Patients were analyzed by dividing them into clopidogrel and prasugrel/ticagrelor groups. Results: Acute coronary syndrome patients (n = 227) who were treated interventionally were included in this retrospective study. Clopidogrel was given to 93 (41%), ticagrelor to 112 (49.3%), and prasugrel to 22 of the patients (9.7%). Compared to the ticagrelor/prasugrel group, the clopidogrel group was older and more were women, and the history of hypertension and previous coronary artery disease was higher (P, respectively: <.001; .001; .008; .0045). The creatinine value was higher, the basal hemoglobin was lower, and the GRACE (Global Registry of Acute Coronary Events) and CRUSADE (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA Guidelines) scores were higher (P, respectively:.026; .002;.002; <.001). The in-hospital bleeding rate was significantly higher in the clopidogrel group (P <.001). Although the in-hospital mortality rate was higher, it was not statistically significant (P = .07). Regression analysis showed that GRACE score and gender were associated with in-hospital mortality (P <.001; P = .031, respectively), and only age was associated with in-hospital bleeding (P <.001). No relationship was found with P2Y12 inhibitor. Conclusion: In our study, we found that the combined use of potent P2Y12 inhibitor with tirofiban in acute coronary syndrome patients treated interventionally was not different from the use of clopidogrel in terms of in-hospital bleeding and mortality.Item A New And Simple Parameter For Diagnosis Pulmonary Edema: Expiratory Air Humidity(2022) Adar, Adem; Can, Emine Yilmaz; Elma, Yusuf; Ferah, Meryem Akpolat; Kececi, Mete; Muderrisoglu, Haldun; Akbay, Ertan; Akinci, Sinan; Coner, Ali; Haberal, Cevahir; Cakan, Fahri; Onalan, Orhan; https://orcid.org/0000-0002-9146-0621; https://orcid.org/0000-0001-5250-5404; 35092906; AAD-5479-2021; AAD-5564-2021Purpose: Acute pulmonary edema is characterized by increased levels of fluid in the interstitial and alveolar space of the lung and requires emergency treatment. In acute pulmonary edema, the amount of fluid in the intra-alveolar, interstitial space, and pleural space vary considerably and this fluid will evaporate in different amounts compared to the physiological fluid. The aim of this study was to compare the humidity rates of expiratory air measured before and after pulmonary edema induced by alpha-naphthylthiourea (ANTU) in rats. Methods: The study included twenty healthy adult rats divided equally into a healthy control group and a pulmonary edema group. Pulmonary edema was induced by administering ANTU intraperitoneally in the rats in the study group. Humidity, temperature, lung weight, pleural effusion, and histopathological changes in the respiratory system due to pulmonary edema were examined in the ANTU group. Control measurments were taken before administration of ANTU and again 4 h after administration of ANTU when lung damage was considred to be at maximum levels. Results: Mean expiratory air humidity was 71.22 +/- 3.59% before ANTU and 56.28 +/- 3.94% after administration of ANTU. The mean humidity difference of -14.94 +/- 5.96% was considered statistically different (p = 0.01). Conclusion: Humidity rate in expiratory air was significantly lower in rats with acute pulmonary edema compared to healthy rats. This result supports the hypothesis that humidity in expiratory air can be considered an important parameter in patients during clinical are follow-up for pulmonary edema. (C) 2022 Elsevier Inc.

In this study, we aimed to document these characteristics and to compare them between female patients with MINOCA and MIOCA. Methods: The study was a subgroup analysis of the MINO-CA-TR study. The study was a multi-center, observational cohort study that was conducted in Turkey between March 2018 and October 2018. In this study, 477 (29.3%) female patients who had been diagnosed with acute myocardial infarction were evaluated. Results: Of these women, 49 (10.3%) were diagnosed with MINOCA (mean age 58.9 +/- 12.9 years) and 428 (89.7%) had a final diagnosis of MIOCA (mean age 67.4 +/- 11.8 years). The prevalence of hypertension, hyperlipidemia, and diabetes mellitus was significantly lower in the MINOCA group than in the MIOCA group. In addition, the MINOCA group had higher rates of recent flu history and non-ST elevation myocardial infarction (NSTEMI) presentation than the MIOCA group. There were significant clinical differences in patients with MINOCA in terms of sex. The female patients were older, had higher systolic blood pressures, and lower hemoglobin levels than male patients. Conclusion: The study revealed that the prevalence of traditional coronary artery disease risk factors was lower in female patients with MINOCA than in those who had final diagnosis of MIOCA.Item Answer Regarding: Potent P2Y12 Inhibitors and Bleeding Complications(2022) Akinci, Sinan; Coner, Ali; Akbay, Ertan; Adar, Adem; Muderrisoglu, Haldun; 36200724Item Which is responsible for target organ damage in masked hypertension? Is it an increase in blood pressure or a disruption of the circadian rhythm?(2021) Akbay, Ertan; Coner, Ali; Akinci, Sinan; Demir, Ali Riza; Toktamis, Aydin; 0000-0002-9146-0621; 0000-0002-5711-8873; 0000-0001-5250-5404; 33870802; AAD-5479-2021; ABD-7321-2021; AAD-5564-2021Masked hypertension (MH) and non-dipping pattern are conditions associated with target organ damage and cardiovascular risk, which are frequently observed together. We aimed to show the relationship between the target organ damage observed in MH and the deterioration in the dipping pattern. Methods Patients who underwent ambulatory blood pressure monitoring (ABPM) and office blood pressure (BP) <140/90 mmHg were retrospectively screened. In ABPM data, those with daytime BP >= 135/85 mmHg and night BP >= 120/70 mmHg were included in the MH group, while the others were included in the normotensive group. The patients were grouped as dipper, non-dipper and reverse-dipper according to ABPM results. Left ventricular mass index (LVMI), glomerular filtration rate (GFR) and serum creatinine levels were used to determine target organ damage. Results 289 patients [mean age 46.6 +/- 12.4 years, 136 (47.1%) males], 154 (53.3%) of whom had MH were included in our study. GFR value was found to be significantly lower, serum creatinine levels and LVMI were significantly higher in patients with MH compared to normotensives (p < .05, for all). When the subgroups were examined, it was found that this difference was associated with the disruption in the dipping pattern. In patients with MH, dipping pattern disruption without change in systolic BP was independently associated with an increase in LVMI (p < .05, for both). Conclusion Target organ damage seen in MH may be due to the deterioration of the dipping pattern.
