Intraoperative Takotsubo Cardiomyopathy: A Case Report.

Takotsubo cardiomyopathy (TTC) is a rare condition associated with transient akinesia of apical segments and hyperkinesia of basal segments of the heart. Although several mechanisms have been proposed to cause direct and indirect myocardial damage owing to catecholamine excess, the underlying pathophysiology remains unknown. An 18-year-old female was referred to our otorhinolaryngology outpatient clinic for a septorhinoplasty. Apart from the fear of surgery, the patient had no other health issues. After the administration of local anesthesia (lidocaine and epinephrine mix), tachycardia storms occurred and soon ended with cardiac collapse. Further evaluation revealed TTC. TTC should be considered, especially in cases of treatment-resistant hemodynamic problems after cardiac resuscitation, and nurses can play a crucial role during the preanesthetic period in helping the patient cope with the stress factors related to the upcoming surgery.

Relationship between Aortic Arch Calcification, Detected by Chest X-Ray, and Renal Resistive Index in Patients with Hypertension.

OBJECTIVE: Aortic arch calcification (AAC) is a surrogate marker for arterial stiffness and hypertension-related vascular damage. Renal resistive index (RRI), a renal Doppler ultrasonography parameter, is used to assess renal hemodynamics. In this study, we aimed to evaluate the relationship between RRI and AAC in patients with hypertension. METHODS: Patients with hypertension underwent a chest X-ray and re nal Doppler ultrasonography. They were divided into two groups according to RRI (group 1: RRI ≥0.70; group 2: RRI < 0.70). Two examiners, blinded to the findings of RRI, reviewed the AAC in these patients. The kappa value was detected to be 0.781 and a p value < 0.001 was considered significant. RESULTS: The study included 289 hypertensive patients (mean age 63.87 ± 11.38 years). In 53.6% (n = 155) of the study subjects, RRI was observed to be ≥0.70. Patients with RRI ≥70 were older and had more prevalent AAC as well as left ventricular hypertrophy. A multiple linear regression analysis was carried out to test whether presence of AAC significantly predicted RRI. The results of the regression analysis indicated that presence of AAC significantly predicted RRI (ß = 0.053; p < 0.001). CONCLUSIONS: A strong and independent relationship was found between AAC on chest X-ray and RRI in patients with hypertension.

Relationship between ST-Segment Shifts in Lead aVR and Coronary Complexity in Patients with Acute Coronary Syndrome.

BACKGROUND: ST-segment shifts in lead aVR are associated with increased coronary atherosclerosis. However, there is insufficient data about the relationship between ST-segment shifts in lead aVR and coronary complexity. The aim of this study was to investigate this relationship. METHODS: This prospective, observational study included 236 patients with acute coronary syndrome who underwent coronary angiography. Electrocardiograms on presentation were reviewed in terms of ST-segment shifts in lead aVR. Inter-observer agreement was analyzed using kappa statistics for the presence of aVR lead ST segment shifts. The patients were divided into two groups according to their Sx scores (≤ 22 and > 22). RESULTS: The mean age of the study population was 62.19 ± 12 years. Eighty-seven patients (37%) had complex coronary artery disease as defined by intermediate-high Sx scores, and 130 patients (55%) had ST-segment shifts in lead aVR. In multivariate logistic regression analysis, ST-segment elevation or depression ≥ 1 mm were independently associated with intermediate-high Sx scores. CONCLUSIONS: In patients with acute coronary syndrome, the presence of ST-segment elevation or depression ≥ 1 mm in lead aVR may indicate coronary complexity.

Pregbalin induced recurrent syncopal attacks with prolong QT interval.

Long QT syndrome may lead to fatal dysrhythmia. Prolongation of QT interval due to pregabalin has been shown in rats and no data is available in humans. We report a 80-year-old female patient using pregabalin. She was presented to emergency room with syncope attacks. Her admission electrocardiography demonstrated prolonged QT interval. After excluding the possible causes of the long QT syndrome, we attributed prolonged QT interval to pregabalin therapy. After discontinuation of pregabalin QT interval returned to normal range and patient experienced no further syncope attacks. It is first time for documentation of prolonged QT due to pregabalin in humans.

Aortic arch calcification is strongly associated with coronary artery calcification.

BACKGROUND: We aimed to investigate the association between aortic arch and coronary artery calcification (CAC). We postulated that low- and high-risk CAC scores could be predicted with the evaluation of standard chest radiography for aortic arch calcification (AAC). PATIENTS AND METHODS: Consecutive patients who were referred for a multidetector computerized tomography (MDCT) examination were enrolled prospectively. All patients were scanned using a commercially available 64-slice MDCT scanner for the evaluation of CAC score. A four-point grading scale (0, 1, 2 and 3) was used to evaluate AAC on the standard posterior-anterior chest radiography images. RESULTS: The study group consisted of 248 patients. Median age of the study group was 52 (IQR: 10) years, and 165 (67 %) were male. AAC grades (r = 0.676, p < 0.0001) and age (r = 0.518, p < 0.0001) were significantly and positively correlated with CAC score. Presence of AAC was independently associated with the presence of CAC (OR: 11.20, 95 % CI 4.25 to 29.52). An AAC grade of ≥ 2 was the strongest independent predictor of a high-risk CAC score (OR: 27.42, 95 % CI 6.09 to 123.52). Receiver operating characteristics curve analysis yielded a strong predictive ability of AAC grades for a CAC score of ≥ 100 (AUC = 0.892, P < 0.0001), and ≥ 400 (AUC = 0.894, P < 0.0001). Absence of AAC had a sensitivity, specificity and accuracy of 90 %, 84 % and 89 %, respectively, for a CAC score of < 100. An AAC grade of ≥ 2 predicted a CAC score of ≥ 400 with a sensitivity, specificity and accuracy of 68 %, 98 % and 95 %, respectively. CONCLUSIONS: AAC is a strong and independent predictor of CAC. The discriminative performance of AAC is high in detecting patients with low- and high-risk CAC scores.

Onychomycosis is associated with subclinical atherosclerosis in patients with diabetes.

BACKGROUND: We aimed to investigate the association of toenail onychomycosis with subclinical atherosclerosis in patients with diabetes mellitus. PATIENTS AND METHODS: Consecutive diabetic patients who were seen at our outpatient clinic were enrolled. The carotid intima-media thickness (CIMT) was assessed and toenail onychomycosis was diagnosed with microscopic evaluation. RESULTS: We investigated 127 patients with diabetes melltus type 2. Overall, the prevalence of toenail onychomycosis was 37.8 % (48 of 127). Of the 127 patients, 60 (47.2 %) had subclinical atherosclerosis (CIMT ≥ 1 mm). Prevalence of male gender (43.3 % vs. 22.4 %, p = 0.012) and onychomycosis (53.3 % vs. 23.9 %, p = 0.001) was significantly higher in patients with subclinical atherosclerosis. Among biochemical parameters, low-density lipoprotein (122 ± 38 mg/dL vs. 108 ± 36 mg/dL, p = 0.039) and glycosylated hemoglobin levels (median 8.4 %, IQR: 2.1 % vs. median 7.5 %, IQR: 1.6 %, p = 0.002) were significantly higher in patients with subclinical atherosclerosis. Study groups were similar with respect to all other demographic, clinical, and laboratory parameters. After adjustment for all potential confounders, the presence of onychomycosis was independently associated with subclinical atherosclerosis (OR 2.77, 95 % CI 1.16 to 6.30) in multivariate logistic regression analysis. CONCLUSIONS: Presence of onychomycosis in patients with diabetes is associated with subclinical atherosclerosis. Onychomycosis may be a marker of atherosclerotic arterial involvement.

Association of Fragmented QRS with Subclinical Left Ventricular Dysfunction in Patients with Obstructive Sleep Apnea.

OBJECTIVE: We aimed to investigate whether fragmented QRS (fQRS) is associated with subclinical left ventricular (LV) dysfunction in patients with obstructive sleep apnea (OSA). SUBJECTS AND METHODS: A total of 141 patients with OSA who had normal LV ejection fraction (LVEF) were included in the study. The fQRS was defined as the presence of an additional R wave, notching of R or S wave or the presence of fragmentation in 2 contiguous electrocardiography (ECG) leads. Subclinical LV dysfunction was defined as the presence of a tissue Doppler-derived Tei index of ≥ 0.5 in the absence of impaired LVEF (<50%) as assessed by transthoracic echocardiography. RESULTS: Of the 141 patients, 71 (50.4%) had subclinical LV dysfunction. Overall, the prevalence of the fQRS was 61% (86/141). Patients with fQRS had significantly higher Tei indices than those without fQRS [median 0.66, interquartile range (IQR) 0.39 vs. median 0.40, IQR 0.15, p < 0.001]. The presence of fQRS on ECG predicted subclinical LV dysfunction in univariate logistic regression analysis [odds ratio (OR) 6.69, 95% confidence interval (CI) 3.10-14.43]. The association remained significant after adjusting for all potential confounders (OR 4.59, 95% CI 1.94-10.87). CONCLUSION: fQRS on ECG was an independent predictor of subclinical LV dysfunction in patients with OSA. This simple tool might help to identify OSA patients who could be at risk for developing overt cardiac dysfunction.

Fragmented QRS is associated with subclinical left ventricular dysfunction in patients with chronic kidney disease.

OBJECTIVE: We aimed to investigate the association of fragmented QRS (fQRS) with subclinical left ventricular (LV) dysfunction in patients with chronic kidney disease (CKD). METHODS AND RESULTS: Patients with CKD who had a normal LV ejection fraction (> or = 50%) were enrolled.The tissue Doppler-derived Tei index was measured for all patients. A Tei index of > or = 0.5 was considered abnormal. Subclinical LV dysfunction was defined as the presence of an abnormal Tei index in the absence of impaired LV ejection fraction (< 50%). The fQRS was defined as the presence of an additional R wave (R') or notching of R or S wave or the presence of fragmentation in two contiguous ECG leads. The study group consisted of 82 patients (45 male, mean age 54 +/- 14 years). Overall, prevalence of fQRS was 60% among CKD patients who had a preserved LV ejection fraction. Of these, 52 (63%) had an abnormal (> or = 0.5) and 30 (37%) a normal Tei index (< 0.5). The prevalence of fQRS was significantly higher in patients with an abnormal Tei index than in patients with a normal Tei index (71% vs. 40%, P = 0.006). Patients with an abnormal Tei index had a lower E/A ratio as compared to patients with a normal Tei index (P = 0.03). Groups were similar with respect to all other variables. In multivariate logistic regression analysis, the presence of fQRS was independently associated (OR 3.52, 95% CI 1.28-9.64) with the presence of an abnormal Tei index after adjustment for potential confounders. CONCLUSION: Fragmented QRS is independently associated with subclinical LV dysfunction in patients with CKD and normal ejection fraction.

Relationship between fragmented QRS complex and left ventricular systolic and diastolic function in kidney transplant patients.

BACKGROUND: Kidney transplant is a most important replacement therapy. It reduces cardiovascular mortality and morbidity but does not fully correct impairments in cardiac function. Fragmented QRS (fQRS) complex includes various RSR' patterns with different QRS complex morphologies on electrocardiograms. OBJECTIVE: To analyze fQRS frequency and the relationship between fQRS and left ventricular function in kidney transplant patients. METHOD: -After demographic data on 39 kidney transplant patients were recorded and biochemical parameters were investigated, electrocardiograms were evaluated for the presence of fQRS. Left ventricular ejection fraction, mitral annular plane systolic excursion, peak early diastolic mitral annular velocities, late diastolic mitral annular velocities, and systolic mitral annular velocity were analyzed. RESULTS: Fragmented QRS was detected in 16 patients. A history of hypertension was associated with the presence of fQRS. Patients with fQRS had significantly lower systolic and peak early diastolic mitral annular velocities, mitral annular plane systolic excursion, and left ventricular ejection fraction than did patients without fQRS (P= .03, .01, <.001, and .03, respectively). CONCLUSION: Detection of fQRS on electrocardiograms may be useful in predicting systolic and diastolic dysfunction of the left ventricle in kidney transplant patients.

Increased frequency of fragmented QRS in patients with severe aortic valve stenosis.

OBJECTIVE: To investigate the presence of myocardial fibrosis determined by fragmented QRS in patients with severe aortic valve stenosis. SUBJECTS AND METHODS: Eighty-seven consecutive patients with severe aortic valve stenosis and 83 age- and gender-matched control subjects were enrolled into this study. Severe aortic valve stenosis was defined as an aortic valve area <1 cm(2), a Vmax >4 m/s, or a mean gradient ≥40 mm Hg. Fragmented QRS was assessed using a 12-lead electrocardiogram. RESULTS: Fragmented QRS was detected in 40 (46%) patients in the aortic valve stenosis group and in 15 (18%) control subjects (p < 0.001). In multivariate binary logistic regression analysis, the presence of aortic valve stenosis was the only independent factor associated with fragmented QRS (OR = 3.69; 95% CI 1.81-7.55, p < 0.001). CONCLUSION: A higher frequency of fragmented QRS was detected in patients with severe aortic valve stenosis compared to controls.

Aortic Arch Calcification Observed on Chest X-Ray May Serve as an Independent Predictor for Recurrent Stroke. / A Calcificação do Arco Aórtico Observada na Radiografia de Tórax Pode Servir Como um Preditor Independente de Acidente Vascular Cerebral Recorrente.

BACKGROUND: Despite advances in diagnostic and treatment modalities, there is a need for predictive markers for recurrent strokes. OBJECTIVES: This study aimed to investigate the relationship between aortic arch calcification (AAC) and stroke recurrence in stroke patients during a one-year follow-up. METHODS: All stroke patients who experienced their first event were evaluated for participation in the study. Patients who experienced recurrent strokes during the one-year follow-up were recorded. AAC was assessed by chest radiography. Based on the occurrence of recurrent strokes the patients were divided into two groups. AAC was classified into four categories according to its degree, and the presence of AAC was included in the statistical analysis. The relationship between AAC and recurrent stroke was assessed using a receiver operating characteristic curve. A significance level of <0.05 was deemed acceptable for all statistical analyses. RESULTS: A total of 203 patients were included in the study (46.8% female, mean age 69±12.3). Recurrent stroke was detected in 49 patients. AAC, hypertension, and atrial fibrillation were more frequent in patients with recurrent stroke. Patients with recurrent stroke had a lower glomerular filtration rate and a higher red cell distribution width (RDW). In multivariate regression analysis, AAC (hazard ratio [HR], 3.544; 95% CI:1.653-7.598, p=0.001) and RDW (HR,1.214; 95% CI:1.053-1.400, p=0.008) were identified as independent predictors of recurrent stroke. CONCLUSION: The presence of AAC (≥ grade 1) and RDW were found to be significantly associated with the development of recurrent stroke within one year. These findings may have prognostic significance in the follow-up of stroke patients.

FUNDAMENTO: Apesar dos avanços nas modalidades de diagnóstico e tratamento, há necessidade de marcadores preditivos para acidente vascular cerebral (AVC) recorrentes. OBJETIVOS: Este estudo teve como objetivo investigar a relação entre calcificação do arco aórtico (CAA) e recorrência de AVC em pacientes com AVC durante o acompanhamento de um ano. MÉTODOS: Todos os pacientes com AVC que sofreram seu primeiro evento foram avaliados para participação no estudo. Foram registrados pacientes que sofreram AVC recorrentes durante o acompanhamento de um ano. A CAA foi avaliada por radiografia de tórax. Com base na ocorrência de AVC recorrente, os pacientes foram divididos em dois grupos. A CAA foi classificada em quatro categorias de acordo com o seu grau, e a presença de CAA foi incluída na análise estatística. A relação entre CAA e AVC recorrente foi avaliada por meio de uma curva característica de operação do receptor. Um nível de significância <0,05 foi considerado aceitável para todas as análises estatísticas. RESULTADOS: Um total de 203 pacientes foram incluídos no estudo (46,8% mulheres, média de idade 69±12,3). AVC recorrente foi detectado em 49 pacientes. CAA, hipertensão e fibrilação atrial foram mais frequentes em pacientes com AVC recorrente. Pacientes com AVC recorrente apresentaram menor taxa de filtração glomerular e maior largura de distribuição de glóbulos vermelhos (RDW). Na análise de regressão multivariada, CAA (hazard ratio [HR], 3,544; IC 95%:1,653-7,598, p=0,001) e RDW (HR,1,214; IC 95%:1,053-1,400, p=0,008) foram identificados como preditores independentes de AVC recorrente. CONCLUSÃO: A presença de CAA (≥ grau 1) e RDW foram significativamente associadas ao desenvolvimento de AVC recorrente dentro de um ano. Esses achados podem ter significado prognóstico no acompanhamento de pacientes com AVC.

Clinical characteristics of atrial fibrillation in nonagenarian population and relationship with mortality.

BACKGROUND: There is a considerable amount of literature available on well-known risk factors for atrial fibrillation (AF); however, available data specifically focused on the ninth decade are scarce. The main objective of this study was to assess the demographic and clinical characteristics of AF and sinus rhythm in a nonagenarian population. METHODS: All individuals aged >90 years who were admitted to the Cardiology outpatient clinic between April 2018 and January 2019 were enrolled in the study. The demographic and clinical characteristics of all patients were recorded. All deaths that occurred during the two-year follow-up period were recorded. RESULTS: In total, 112 nonagenarian individuals were included in the study. Of these patients, 50 (44.6%) had AF. The groups showed similarities in demographic and clinical characteristics. During a mean follow-up period of 596±44 days, 39 patients (78%) in the AF group and 35 patients (56.5%) in the sinus group died. Patients with AF showed a lower overall survival distribution than those with sinus rhythm (P=0.005, log-rank test χ2=7.734). AF was associated with an increased risk of mortality (P=0.002, hazard ratio [HR] =2.104, 95% confidence interval [CI] = 1.326-3.339) in multivariate Cox regression analysis, while waist circumference and total cholesterol (P=0.003, HR=0.969, 95% CI=0.949-0.989 and P=0.046, HR=0.993, 95% CI=0.986-1.000, respectively) showed a decreased risk of mortality. CONCLUSIONS: Atrial fibrillation is very common in individuals over the age of 90 years (44.6%). Well-known risk factors do not appear to be effective in this age group, and AF is associated with a 2.1-fold increase in the risk of mortality.

Aortic knob calcification and coronary artery lesion complexity in non-ST-segment elevation acute coronary syndrome patients.

OBJECTIVES: Coronary artery lesion complexity is important for risk stratification of acute coronary syndrome (ACS) patients undergoing cardiac catheterization. SYNTAX score is a pure angiographic measure of anatomic coronary complexity. Chest radiography is a routine examination for evaluating patients with chest pain. There have been no studies to date exploring the relation between aortic knob calcification (AKC) and coronary lesion complexity assessed by SYNTAX score. STUDY DESIGN: 135 consecutive patients with first time diagnosis of non-ST segment elevation ACS were enrolled. SYNTAX score was calculated by dedicated computer software. Aortic calcification was assessed visually. RESULTS: Patients with AKC had higher SYNTAX score compared to those without AKC (16±6 vs. 11±7, p=0.019). Also, patients with AKC had higher TIMI risk score and were more elderly. Linear regression analysis demonstrated AKC (95% confidence interval [CI] 1.7-6.9, p=0.002), diabetes (95% CI, 1.1-5.7, p=0.005), and smoking (95% CI, 1.2-13.5, p=0.004) as independent determinants of SYNTAX score. CONCLUSION: Aortic calcification detected on chest X-ray is an independent predictor of complex coronary artery lesions in patients with ACS.

Increased leucocyte count could predict coronary artery calcification in patients free of clinically apparent cardiovascular disease.

OBJECTIVES: Several studies have demonstrated that inflammation plays a major role in the development of atherosclerosis and that the inflammatory process might also be involved in coronary artery calcification (CAC). The main purpose of this study was to investigate the relation between leucocyte count and CAC and to determine whether a higher leucocyte count could indicate subclinical atherosclerosis in patients without overt cardiovascular disease. STUDY DESIGN: A total of 284 consecutive patients (156 men, 128 women) without established cardiovascular disease were enrolled. CAC was measured using cardiac computed tomography. Leucocyte count was measured via routine blood examination. RESULTS: Patients with CAC had higher leucocyte counts compared to those without calcification (7.87±1.85 vs. 6.01±1.84; p<0.001). Logistic regression analysis identified the following as independent predictors of CAC: leucocyte count (odds ratio [OR]: 1.7, 95% confidence interval [CI]: 1.3-2.1), smoking (OR: 2.4, 95% CI: 1.2-4.6) and age (OR: 1.2, 95% CI: 1.1-2.3). There was also a significant correlation between CAC and leucocyte count (r=0.57, p<0.001). CONCLUSION: We demonstrated that leucocytes may play an important role in the evolution of CAC and may be used in the detection of subclinical atherosclerosis in asymptomatic subjects.

Association of Morning Surge and Postexercise Heart Rate and Blood Pressure Recovery.

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 (ß: 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.

Association of the Atherogenic Index of Plasma with C-Reactive Protein and Urinary Albumin Excretion in a Normotensive Nondiabetic Population.

Background: The atherogenic index of plasma (AIP) is an indicator of atherogenic dyslipidemia and is significantly associated with the development of atherosclerotic cardiovascular disease. Previous studies showing the association of AIP with C-reactive protein (CRP) and microalbuminuria included hypertensive and diabetic patients. We aimed to determine the association of AIP with CRP and albuminuria in a normotensive and nondiabetic population. Methods: The study was conducted retrospectively. Two hundred thirty-three individuals without hypertension, diabetes, cardiovascular disease, malignancy, systemic inflammatory disease, nephrological disease, and active infection were determined and included in the study. Urinary albumin excretion was calculated from the albumin-creatinine ratio in fresh spot urine [urinary albumin-creatinine ratio (UACR)]. AIP risk groups were compared in terms of clinical and laboratory findings, and the correlation between AIP and CRP and UACR was evaluated. Results: A total of 233 people, with a mean age of 45.4 years and 139 (69.7%) of whom were male, were included in the study. One hundred thirty-eight (59.2%) individuals were found to be in the low-risk group, 29 (12.5%) in the medium-risk group, and 66 (28.3%) in the high-risk group, according to the AIP value. CRP and UACR were not different between the AIP risk groups (P: 0.141 and 0.441, respectively). A mild correlation was found between AIP and CRP (r: 0.192; P: 0.003), but no correlation was found between AIP and UACR (r: 0.086; P: 0.193). The stepwise linear regression analysis with model adjusted for possible confounders and AIP revealed that only body mass index was a significant predictor of CRP (ß: 0.308; P < 0.001), while only systolic blood pressure was a significant predictor of UACR (ß: 0.19; P: 0.004), but AIP was not. Conclusions: AIP was not associated with CRP and UACR in normotensive and nondiabetic individuals. This finding suggests that the relationship found in previous studies is related to the presence of hypertension or diabetes rather than the AIP.

In-Hospital Bleeding and Mortality in Acute Coronary Syndrome Patients Treated with Tirofiban and Potent P2Y12 Inhibitors.

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 signifi- cantly 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 tiro- fiban in acute coronary syndrome patients treated interventionally was not different from the use of clopidogrel in terms of in-hospital bleeding and mortality.

New perspective on fatigue in hemodialysis patients with preserved ejection fraction: diastolic dysfunction : Fatigue and diastolic dysfunction.

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.

Evaluation of the relationship between para-aortic adipose tissue and ascending aortic diameter using a new method.

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.

A new and simple parameter for diagnosis pulmonary edema: Expiratory air humidity.

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 α-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.
