Background Masked hypertension is directly related to increased cardiovascular morbidity and mortality but remains underdiagnosed in clinical practice. The aim of the study was to search the role of aortic arch calcification (AAC) in the diagnosis of masked hypertension. Methods and results Among the patients who underwent ambulatory blood pressure monitoring (ABPM) in our clinic, those with office blood pressure (OBP) <140/90 mmHg were included in the study population. According to OBP, they were divided into two groups as normal (<130/85 mmHg) and high normal (130-139/85-89 mmHg) OBP groups. Subjects were also investigated for the presence of masked hypertension with ABPM and searched in masked hypertension and control groups. Masked hypertension was defined as in the latest 2017 ACC/AHA Hypertension guideline and was diagnosed as the daytime BP >= 135/85 mmHg and nighttime BP >= 120/70 mmHg. AAC was evaluated on direct X-ray telecardiography. Diagnosis of masked hypertension was searched depending on the presence of AAC and OBP measurements as well. A total of 216 volunteers were involved in the study [mean age 45.2 +/- 12.2 years; female gender 120 (55.5%)]. One hundred ten volunteers (50.9%) had masked hypertension according to the ABPM. AAC was significantly more common in the masked hypertension group (44.5% vs. 26.4%) (P = 0.005). AAC had a positive predictive value of 79% in those with high normal OBP in the diagnosis of masked hypertension, and also AAC had a negative predictive value of 74% in those with normal OBP. Conclusion AAC can be used as a reliable diagnostic tool to exclude and predict masked hypertension during office examination.

Introduction The autonomic nervous system plays an active role in the regulation of early morning blood pressure (BP) and BP/pulse regulation in the treadmill exercise test (TET). Aim We evaluated the relationship between BP/pulse changes during TET and morning blood pressure surge (MS). Methods Patients who underwent ambulatory blood pressure measurement (ABPM) and TET in the same visit between 2017 and 2020 were evaluated retrospectively. Patients with previously diagnosed hypertension and/or using antihypertensives and office BP >= 140/90 were excluded from the study.MS values and dipping percentage were calculated from ABPM data. The patients were analyzed by dividing them into two groups according to the MS median, and BP/pulse values during exercise and recovery periods were compared in these groups. Results 202 patients [median age 45 (39-51), male 134 (66.3%)] were included in the study. MS median was 18.5 (10.75-27) mmHg. TET recovery period 3rd-min systolic blood pressure (RSBP) was higher in the group with high MS (p: 0.017). Systolic and diastolic dipping percentages were higher in the group with higher MS (p: 0.015, p: 0.040, respectively). Peak systolic and diastolic BP, RSBP, and recovery 3rd min diastolic BP were positively correlated with MS (p < 0.05, for all). Additionally, an independent relationship was observed between RSBP and MS (beta: 0.205, p: 0.028). Conclusion We found an independent association between RSBP and MS. Increased RSBP may be associated with target organ damage and cardiovascular events such as MS.

Objective: The role of dipping blood pressure pattern in normotensives is unclear. The study aims to search the circadian blood pressure rhythm and the clinical determinants related to reverse dipping pattern in a strictly selected, normotensive population. Methods: The study population was divided into three groups depending on the nocturnal dipping pattern as dipping, non-dipping, and reverse dipping. Basal clinical characteristics, anthropometric measurements, and spot urine samples from the first-morning void were collected. Clinical determinants related to the presence of reverse dipping pattern were tested by the Multiple Binary Logistic Regression analysis. Results: A total of 233 participants were involved in the study population (median age 45 years [40-50]). Dipping pattern was detected in 55.4%, non-dipping pattern in 33.0%, and reverse dipping pattern in 11.6% of the study population. There was no difference between the groups in terms of basal clinical features. Albumin-to-creatinine ratio (ACR) (p < .001) and hs-CRP levels (p = .006) were also statistically significant across the groups. ACR (HR: 1.195, 95% CI: 1.067-1.338, p = .002) and hs-CRP (HR: 2.438, 95% CI: 1.023-5.808, p = .044) were found to be related to the presence of reverse dipping blood pressure pattern. Conclusions: The absence of nocturnal physiological dipping is seen at a remarkable rate in the normotensive Turkish population. ACR and hs-CRP are the clinical determinants related to the presence of reverse dipping blood pressure pattern.

Background Para-aortic adipose tissue (PAT) is the local adipose tissue that externally surrounds the aorta. It contributes significantly to aortic atherosclerosis and enlargement. Studies conducted with computed tomography and magnetic resonance have shown that individuals with aortic aneurysm had more PAT than healthy individuals. In this study, we measured PAT using transthoracic echocardiography (TTE). The aim of this study is to investigate the possible relationship of TTE measured PAT with ascending aortic width. Methods PAT was defined as the hypoechoic space in front of ascending aortic 2 cm above the sinotubular junction at the end of the systole. Patients were divided into 2 groups according to the presence of dilatation in the ascending aorta using Roman's classification (aortic size index, ASI). ASI of less than 21 was considered no aortic dilation and an ASI of 21 mm/m2 or greater was considered to have aortic dilation. Results A total of 321 unselected patients were divided into the ascending aortic dilatation (AAD) group (n = 96) and the normal ascending aorta diameter group (n = 225 patients). PAT was significantly higher in the AAD group compared with the non-ADD group (0.9 (0.48) vs. 0.7 (0.91) mm, p < 0.0001). Univariate and multivariate logistic regression analysis revealed that PAT (OR: 3.005, 95%CI (1.445-6.251)) were significantly associated with AAD. Conclusions This is the first study which evaluated PAT measured by TTE. We found a significant association between PAT measured by TTE and ascending aorta width.

(2021) Akinci, Sinan; Coner, Ali; Akbay, Ertan; Muderrisoglu, Ibrahim Haldun; 0000-0002-9146-0621; 0000-0001-5250-5404; 0000-0002-5711-8873; 34549694; AAD-5479-2021; AAD-5564-2021; ABD-7321-2021
Aim The autonomic nervous system plays an important role in the pathogenesis of vasovagal syncope, but studies on the effect of basal autonomic tone have found confusing results. The aim of this study was to investigate the effect of basal autonomic functions, as assessed by heart rate variability (HRV) and heart rate turbulence (HRT), in patients with vasovagal syncope. Material and methods Patients who underwent head-up tilt test (HUTT) due to unexplained syncope and who had a 24-hr Holter ECG recording in the same period were retrospectively analyzed. Patients with diabetes, a history of myocardial infarction, heart failure, orthostatic hypotension, atrial fibrillation, or use of vasoactive drugs, such as beta blockers, were excluded from the study. 161 patients who met these criteria were included in the study. Time domain HRV parameters from Holter ECG recordings and HRT parameters from patients with sufficient number of ventricular premature contractions were measured. Results The age of the patients varied from 16 to 75 yrs (mean: 44.8 +/- 18.5 yrs). HUTT results of 60 (37.2%) patients were evaluated as positive. There were no significant differences in the basal demographic, clinical, or laboratory findings of the tilt-positive and tilt-negative patient groups. Likewise, there were no significant differences between the time domain HRV parameters and HRT parameters of both groups. Conclusion HRV and HRT parameters reflecting basal autonomic function were not different between HUTT positive and HUTT negative patient groups. These findings suggest that basal autonomic functions have no effect on vasovagal syncope pathogenesis.

(2022) Akinci, Sinan; Coner, Ali; Akbay, Ertan; Adar, Adem; Muderrisoglu, Haldun; 35860883
Objective: In this study, we aimed to determine whether potent agents affect in-hospital bleeding and mortality compared to clopidogrel in patients with the acute coronary syndrome in whom tirofiban and P2Y12 inhibitor are used together. 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.

(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-5564-2021
Purpose: 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.

(2022) Akbay, Ertan; Coner, Ali; Akinci, Sinan; Adar, Adem; Demir, Ali Riza; Uygur, Begum; Saba, Tonguc; Budak, Ali Baran; Muderrisoglu, Ibrahim Haldun
Objective: Saphenous vein graft failure (VGF) is a measure of the short-and long-term success of coronary artery bypass graft surgery (CABG). Aortic arch calcification (AAC) is a long-term finding of atherosclerosis in large vessels. The aim of this study was to evaluate the relationship between AAC and VGF.Materials and Methods: Patients who underwent CABG surgery and subsequent coronary angiography in a single hospital between January 2010 and January 2021 were included in the study. The presence and stage of AAC was evaluated using preoperative chest X-rays. VGF was defined as >= 75% stenosis and/or total occlusion in the saphenous vein graft. In addition, the effect of AAC on VGF was evaluated based on the time elapsed since the CABG procedure. Results: Of the 594 patients who underwent CABG during the study period, 91 patients (mean age 63.6 +/- 10.0; 71 [78.0%] male) were included in the study. VGF was observed in 49 (53.8%) patients. AAC was found to be an independent predictor of VGF (odds ratio [OR]: 2.788, 95% confidence interval [CI]: 1.068-7.278). The results indicated no association between AAC and VGF in patients whose coronaries were screened within 1 year (OR: 1.143, 95% CI: 0.279-4.683), while there was a strong association between AAC and VGF in patients who were screened 1 year after the surgery (OR: 5.355, 95% CI: 1.618-17.720).Conclusion: AAC evaluation may be a valuable diagnostic method to predict VGF after CABG, and particularly late VGF.
New Perspective On Fatigue In Hemodialysis Patients With Preserved Ejection Fraction: Diastolic Dysfunction Fatigue And Diastolic Dysfunction
(2022) Akbay, Ertan; Akinci, Sinan; Coner, Ali; Adar, Adem; Genctoy, Gultekin; Demir, Ali Riza; https://orcid.org/0000-0002-9146-0621; https://orcid.org/0000-0001-5250-5404; AAD-5479-2021; AAD-5564-2021
The relationship between diastolic dysfunction and fatigue in hemodialysis patients with preserved ejection fraction is unknown. In this context, the objective of this study is to assess fatigue using the relevant scales and to demonstrate its relationship with diastolic dysfunction. The patients who underwent hemodialysis were evaluated prospectively. Patients' fatigue was assessed using the Visual Analogue Scale to Evaluate Fatigue Severity (VAS-F). The echocardiographic works were performed as recommended in the American Society of Echocardiography guidelines. A total of 94 patients [mean age 64.7 +/- 13.5 years, 54 males (57.4%)] were included in the study. The median VAS-F score of these patients was 68.5 (33.25-91.25), and they were divided into two groups according to this value. Peak myocardial velocities during early diastole (e ') and tricuspid annular plane systolic excursion (TAPSE) values were found to be significantly lower in the group with high VAS-F scores, whereas the early diastolic flow velocities (E)/e ' ratio and pulmonary artery peak systolic pressures (PAP) were found to be significantly higher (p < 0.05, for all). E/e ' ratio (r 0.311, p 0.002) and PAP (r 0.281, p 0.006) values were found to be positively correlated with the VAS-F score, as opposed to the TAPSE (r - 0.257, p 0.012) and e ' (r - 0.303, p 0.003) values, which were found to be negatively correlated with the VAS-F score. High fatigue scores in hemodialysis patients may be associated with diastolic dysfunction. In addition, in our study, we determined the correlation of VAS-F score with E/e ' ratio, PAP and TAPSE.
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-5564-2021
Masked 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.
