Purpose: the aim of this study is to investigate whether P wave dispersion (PWD), measured before, during and after fibrinolytic therapy (FT,) is able to predict successful reperfusion and infarct related artery (IRA) patency in patients with acute anterior MI who received FT. Methods: Sixty-eight patients who presented with acute anterior MI were enrolled in the study. An electrocardiogram was performed before and at 30, 60, 90 and 120 minutes after the start of FT. PWD was defined as the difference between maximum and minimum P wave duration on standard 12-lead surface electrocardiogram. A multivariate logistic regression model wa . . .s used to assess whether PWD was predictor of IRA patency and STsegment resolution (STR) on electrocardiogram. Results: PWD 120 was significantly lower in patients with STR on electrocardiogram (38 patients) compared with those without STR (30 patients) (44.8±11.5 vs. 52.9±10.3 ms; p<0.001). PWD 120 was found to be significantly lower in patients with patent IRA (31 patients) compared to those with occluded IRA (37 patients) (42.3±9.7 vs. 53.5±10.6 ms; p<0.001). Logistic regression analysis revealed that PWD120 significantly predicted STR and IRA patency. A ?51.6 ms PWD 120 can predict an occluded IRA with a 87% sensitivity, ?51 ms PWD 120 can predict no reperfusion with a 74% sensitivity. Conclusion: PWD values, which were higher than 51 ms and 51.6 ms in patients who received fibrinolytic therapy, can serve as a marker of failed reperfusion and occluded IRA. PWD values, in combination with other reperfusion parameters, can contribute to the identification of rescue PCI candidates. © 2012 CIM Daha fazlası Daha az

Article | 2017 | Korean Journal of Internal Medicine32 ( 2 ) , pp.286 - 294

Background/Aims: The aim of this study was to investigate atrial conduction times and left atrial mechanical functions, the noninvasive predictors of atrial fibrillation, in prediabetic patients with impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). Methods: Study included 59 patients (23 males, 36 females; mean age 52.5 ± 10.6 years) diagnosed with IFG or IGT by the American Diabetes Association criteria, and 43 healthy adults (22 males, 21 females; mean age 48.5 ± 12.1 years). Conventional and tissue Doppler echocardiography were performed. The electromechanical delay parameters were measured from the onset of t . . .he P wave on the surface electrocardiogram to the onset of the atrial systolic wave on tissue Doppler imaging from septum, lateral, and right ventricular annuli. The left atrial volumes were calculated by the disk method. Left atrial mechanical functions were calculated. Results: The mitral E/A and E’/A’ ratios measured from the lateral and septal annuli were significantly lower in the prediabetics compared to the controls. The interatrial and left atrial electromechanical delay were significantly longer in prediabetic group compared to the controls. Left atrial active emptying volume (LAAEV) and fraction (LAAEF) were significantly higher in the prediabetics than the controls. LAAEV and LAAEF were significantly correlated with E/A, lateral and septal E’/A’. Conclusions: In the prediabetic patients, the atrial conduction times and P wave dispersion on surface electrocardiographic were longer before the development of overt diabetes. In addition, the left atrial mechanical functions were impaired secondary to a deterioration in the diastolic functions in the prediabetic patients. © 2017 The Korean Association of Internal Medicine Daha fazlası Daha az

Karabag T. | Aydin M. | Dogan S.M.

Article | 2013 | Turkiye Klinikleri Cardiovascular Sciences25 ( 1 ) , pp.26 - 28

Oxcarbazepine, 10 keto analogue of carbamezepine, is an antiepileptic drug used pri manly for the treatment of focal and generalized tonic clonic seizures in adults and children. Ox carbazepine has been observed to have a positive effect also on psychiatric diseases and trigeminal neuralgia. Oxcarbazepine like most of antiepileptic drugs, inhibits voltage dependent fast sodium channels. During oxcarbazepine treatment, side effects such as hyponatremia, headache, vertigo, somnolence, nausea, double vision, vomiting and ataxia can be seen. However, to date, no specific and!or severe cardiac complications of oxcarbazepine have been rep . . .orted. In this paper, we present a case of complete atrioventricular block that was considered to be caused by oxcarbazepine and that improved after cessation of the drug in a 67 year old female patient with no underlying cardiac etiology.

BACKGROUND: QRS prolongation and the presence of QRS fragmentation in 12-lead ECG are associated with increased mortality and sudden cardiac death in the long term. In this study we aimed to assess QRS duration and fragmentation in patients with Behçet's disease (BD). METHODS: A total of 50 patients (mean age 42.7±12.0 years) previously diagnosed with BD were recruited. In addition, a control group consisting of 50 healthy people (mean age 39.4±12.5 years) was formed. The longest QRS duration was measured in surface 12-lead ECG and QRS complexes were evaluated in terms of fragmentation. Serum C-reactive protein levels were also obta . . .ined. RESULTS: QRS duration and corrected QT duration were significantly longer in patients with BD compared with controls (102.75±11.91 vs. 96.99±10.91 ms, P=0.007; 438.55±30.80 vs. 420.23±28.06 ms, P=0.003, respectively). Fragmented QRS (fQRS) pattern was more common in patients with BD than controls [n=27 (54%) vs. n=16 (32%), P=0.026]. Disease duration was longer in patients with BD with fQRS compared with those without (12.67±8.68 vs. 7.09±7.06 years, P=0.010). Furthermore, C-reactive protein level was higher in patients with BD with fQRS compared with those without (6.53±4.11 vs. 4.97±6.32 mg/dl, P=0.043). Correlation analysis revealed no association between disease duration and QRS duration (r=0.219, P=0.126). CONCLUSION: QRS duration is greater and fQRS complexes are more frequent in patients with BD. These findings may indicate subclinical cardiac involvement in BD. Given the prognostic significance of ECG parameters, it is reasonable to evaluate patients with BD with prolonged and fQRS complexes more in detail such as late potentials in signal averaged ECG in terms of cardiac involvement. © 2013 Wolters Kluwer Health / Lippincott Williams & Wilkins Daha fazlası Daha az

Backgrounds: Charlson Comorbidity index (CCI) is a scoring system to predict prognosis and mortality. It exhibits better utility when combined with age, age-adjusted Charlson Comorbidity Index (ACCI). The aim of this study was to evaluate the relationship between ACCI and diurnal variation of blood pressure parameters in hypertensive patients and normotensive patients. Methods: We enrolled 236 patients. All patients underwent a 24-h ambulatory blood pressure monitoring (ABPM) for evaluation of dipper or non-dipper pattern. We searched the correlation between ACCI and dipper or non-dipper pattern and other ABPM parameters. To further . . . investigate the role of these parameters in predicting survival, a multivariate analysis using the Cox proportional hazard model was performed. Results: 167 patients were in the hypertensive group (87 patients in non-dipper status) and 69 patients were in the normotensive group (41 patients in non-dipper status) of all study patients. We found a significant difference and negative correlation between AACI and 24-h diastolic blood pressure (DBP), awake DBP, awake mean blood pressure (MBP) and 24-h MBP and awake systolic blood pressure(SBP). Night decrease ratio of blood pressure had also a negative correlation with ACCI (p = 0.003, r = -0.233). However, we found a relationship with non-dipper pattern and ACCI in the hypertensive patients (p = 0.050). In multivariate Cox analysis sleep MBP was found related to mortality like ACCI (p = 0.023, HR = 1.086, %95 CI 1.012–1.165) Conclusion: ACCI was statistically significantly higher in non-dipper hypertensive patients than dipper hypertensive patients while ACCI had a negative correlation with blood pressure. Sleep MBP may predict mortality. © 2018, © 2018 Taylor & Francis Daha fazlası Daha az

Sayin M.R. | Akpinar I. | Karabag T. | Dogan S.M. | Aydin M.

Article | 2013 | Journal of Cardiology Cases8 ( 1 ) , pp.391 - 392

Dual left anterior descending coronary artery (LAD) is a rare coronary anomaly and is divided into six subgroups in the literature according to the origin and course of the short and long branches of the anomalous artery. We present two distinct cases of dual LAD which are distinguished by two branches of equal length from their counterparts in the literature. Learning objective: In our cases a novel dual LAD variant is presented with two main branches of equal length and reaches the cardiac apex. Cardiologists and cardiovascular surgeons should be aware of these variants to avoid misinterpretation of coronary angiography and intrao . . .perative complications. © 2013 Japanese College of Cardiology Daha fazlası Daha az

Article | 2012 | European Heart Journal Cardiovascular Imaging13 ( 3 ) , pp.251 - 256

Aims: To investigate the atrial electromechanical delay (EMD) duration that is a non-invasive predictor of atrial fibrillation (AF) in patients with Behcet's disease (BD). Methods and results: Thirty-eight Behcet's patients (24 females, 14 males; mean age: 43.6 ± 10.3 years) who were being followed in the dermatology or internal medicine department and 29 demographically matched controls (13 females, 16 males; mean: age 42.6 ± 11.1 years) were included in the study. The inclusion criteria were recurrent oral ulcerations and two of the following features: recurrent genital ulceration, eye lesions, skin lesions or positive pathergy sk . . .in test for Behcet's group. Using tissue Doppler imaging, atrial electromechanical coupling [time interval from the onset of P wave on surface electrocardiogram to the beginning of A wave interval with tissue Doppler echocardiography (PA)] were measured from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septum), and right ventricular tricuspid annulus (PA tricuspid). The mean disease duration was 10.5 ± 7.7 years. The inter-atrial and intra-atrial EMD were significantly higher in the Behcet group than those in the controls (19.8 ± 8.2 vs. 13.1 ± 4.4 ms, P = 0.001; 11.5 ± 7.4 vs. 6.9 ± 3.7 ms, P = 0.02; respectively). The left atrial EMD was similar in both of the groups. However, the P max and PWD values were significantly higher in the BD group compared with those in the controls (120.5 ± 10.1 vs. 112.1 ± 5.9 ms, P < 0.0001; 44.9 ± 10.7 vs. 28.4 ± 5.9 ms, P < 0.0001; respectively). Conclusion: Atrial electromechanical conduction times were increased in the BD patients compared with those in the controls. The tendency of BD patients to go into AF can be easily and non-invasively detected using tissue Doppler echocardiography. These findings may be indicators for subclinical cardiac involvement.

Sayin M.R. | Dogan S.M. | Aydin M. | Karabag T.

Article | 2011 | Canadian Journal of Cardiology27 ( 6 ) , pp.8.70E+19 - 8.70E+21

An unusual type of food poisoning, mad honey poisoning, is a well-known phenomenon in the Black Sea region of Turkey. Mad honey poisoning can result in severe cardiac complications including sinus bradycardia, nodal rhythm, various degrees of atrioventricular blocks, and even asystole. However, no cases of long QT interval have been reported so far. This paper reports the first case of extremely long QT interval to be associated with mad honey consumption. © 2011 Canadian Cardiovascular Society.

Article | 2012 | Texas Heart Institute Journal39 ( 1 ) , pp.116 - 118

Lymphomatoid granulomatosis is a rare, diffuse, large B-cell lymphoma that is positive for Epstein-Barr virus. A multiorgan process, it manifests itself chiefly in the lungs but can also affect the skin, nervous system, and kidneys. Cardiac involvement and pericardial effusion are very unusual. We report the case of a 62-year-old man with lymphomatoid granulomatosis involving the heart and lungs. Diagnosis was confirmed with wedge biopsy at pericardiotomy, and the patient was treated with cyclophosphamide, prednisolone, and vincristine. Although the patient was still symptomatic at 6-month follow-up, he was in partial remission with . . . improved functional capacity. © 2012 by the Texas Heart ® Institute, Houston Daha fazlası Daha az
