Öğe Acute myocardial infarction in a patient with essential thrombocythemia treated with glycoprotein IIb/IIIa inhibitor(Sage Publications Inc, 2004) Gül, Ç; Kürüm, T; Demir, M; Özbay, G; Vural, Ö; Iqbal, O; Fareed, JEssential thrombocythemia (ET) rarely causes obstruction of coronary arteries or acute myocardial infarction. Treatment of acute myocardial infarction in patients with ET may be a problem due to the important role of platelets in the pathogenesis of infarction. There is no reported case of acute myocardial infarction with essential thrombocythemia treated with a glycoprotein IIb/IIIa inhibitor. In this report, a 49-year-old woman with essential thrombocythemia, admitted with a diagnosis of acute inferolateral myocardial infarction, was treated with tirofiban, a glycoprotein IIb/IIIa receptor blocker.Öğe Antianginal and anti-ischemic effects of nisoldipine and ramipril in patients with syndrome X(Clinical Cardiology Publ Co, 1999) Özçelik, F; Altun, A; Özbay, GBackground: Syndrome X is defined as typical angina pectoris, positive treadmill exercise test, negative intravenous ergonovine test, and angiographically normal coronary arteries. Hypothesis: In the present study, we investigated the antiischemic and antianginal effects of nisoldipine and ramipril in patients with syndrome X. Methods: After 2 weeks of the first wash-out period, 18 patients (7 men, 11 women, age 46 +/- 10 years) were given nisoldipine (NIS) 5 mg twice daily for 4 weeks, and after 2 weeks of the second wash-out period, the same patients were given ramipril (RAM) 2.5 mg once daily for 4 weeks. A treadmill exercise test with modified Bruce protocol was performed at the end of each period. Results: The time to angina in exercise (607 +/- 115 s-650 +/- 117 s, p = 0.006, vs. 630 +/- 114 s-660 +/- 123 s, p = 0.02), total exercise time (612 +/- 110 s-656 +/- 114 s, p = 0.0008, vs. 630 +/- 114 s-660 +/- 123 s, p = 0.02), and maximum MET value (11.09 +/- 2.08-11.86 2.04, p = 0.0016, vs. 11.42 +/- 2.09-12.2 +/- 2.26, p = 0.01) were increased significantly with both therapy modalities. The time to 1 mm ST-segment depression(123 +/- 93 s - 220 +/- 172 s, p = 0.002) was increased significantly with NIS therapy. The time to ST-segment recovery (434 +/- 268 s-330 +/- 233 s, p = 0.016 vs. 443 +/- 259 s-370 +/- 278 s, p = 0.012), the frequency of anginal attacks per week (1.27 +/- 1.4-0 +/- 0.38, p = 0.005, vs. 1 +/- 1.32-0.33 +/- 0.59, p = 0.028), and the need for sublingual nitroglycerin (1.16 +/- 1.29-0.11 +/- 0.32, p = 0.005, vs. 0.94 +/- 1.16-0.27 +/- 0.57, p = 0.012) were decreased significantly with both drugs. Conclusion: We observed that 10 mg daily NIS and 2.5 mg daily RAM have similar anti-ischemic and antianginal effects in patients with syndrome X.Öğe Arterial distensibility as determined by carotid-femoral pulse wave velocity in patients with Behcet's disease(Springer, 2005) Kürüm, T; Yildiz, M; Soy, M; Özbay, G; Alimgil, L; Tüzün, BBehcet's disease (BD) is a chronic, multisystem disorder characterized by genital and oral aphthae, skin lesions, uveitis, and tendency to thrombosis. Pulse wave velocity (PWV) is an important factor in determining cardiovascular mortality and morbidity. It is an index of arterial wall stiffness and inversely related to the arterial distensibility. In this study we investigated the arterial distensibility in BD by PWV. We studied 14 patients with BD ( 18 - 44 years old, 10 men) and 28 healthy subjects ( 18 - 39 years old, 21 men) without known cardiovascular disease. Arterial distensibility was assessed by automatic carotid-femoral PWV measurement using the Complior Colson device. PWV is calculated from measurements of pulse transit time and the distance traveled by the pulse between two recording sites, according to the following formula: pulse wave velocity (m/s)= distance (m)/transit time(s). The mean ages, systolic blood pressure, diastolic blood pressure, pulse pressure, heart rate, and PWV of Behcet's disease and control subjects were 32.1 +/- 7.4 vs 27.9 +/- 6.1 years, 112.9 +/- 12.0 vs 108.7 +/- 10.0 mmHg, 72.1 +/- 10.7 vs 67.7 +/- 7.5 mmHg, 40.7 +/- 12.2 vs 41.0 +/- 10.7 mmHg, 74.1 +/- 10.2 vs 77.2 +/- 10.1 bpm, and 8.4 +/- 1.4 vs 8.5 +/- 1.1 m/s, respectively. Differences between all parameters studied were not found to be statistically significant ( p> 0.05). The carotid-femoral PWV, an index of arterial stiffness and a marker of atherosclerosis, is not increased in patients with BD compared with control subjects.Öğe Automatic backscatter analysis of regional right ventricular systolic function using color kinesis in patients with inferior wall acute myocardial infarction(Medimond S R L, 1999) Kürüm, T; Korucu, C; Özçelik, F; Eker, H; Öztekin, E; Özbay, G[Abstract Not Available]Öğe A case of primary anti phospholipid syndrome who developed acute myocardial infarction followed by early-onset pre-eclampsia(Springer-Verlag, 2003) Kürüm, T; Soy, M; Karahasanoglu, E; Özbay, G; Sayin, NC[Abstract Not Available]Öğe Differentiating the infarct-related artery on initial electrocardiogram in single or multi-vessel disease in acute inferior myocardial infarction and evaluating involvement of vessels using correspondence analysis(Westminster Publ Inc, 2005) Kürüm, T; Birsin, A; Özbay, G; Türe, MInitial electrocardiography changes were compared prospectively with the findings of coronary angiography to predict the infarct-related artery (IRA) in cases of single- and multi-vessel disease and to demonstrate the relationship between other coexisting coronary involvements and IRA in patients who presented with acute inferior myocardial infarction (AMI). ST elevations or depressions of at least 1 mm (0.1 mV) were evaluated in the leads 1, aVL, and V-1-V-6. Of the 160 patients hospitalized due to inferior AMI, 153 (96%) underwent coronary angiography using standard methods. The angiograms were screened for stenotic lesions using quantitative coronary angiography to confirm significance, which was considered > 50% vessel lumen diameter reduction. Among single-vessel involvements, the IRA was either the circumflex artery (Cx) or right coronary artery (RCA). In conditions in which IRA was detected as either Cx or RCA, 1-, 2-, and 3-vessel involvements were also detected. Correspondence analysis was performed to show the vessel involvements accompanying IRA. Compared with patients with IRA as RCA, the presence of ST depressions in the leads V-1 or V-2 and aVL were more frequently seen in patients with IRA as Cx (p = 0.000, p = 0.015, respectively). Among all vessel involvements in which IRA was either Cx or RCA, a ST-segment depression in leads V-1 or V-2 (P = 0-000) and aVL (p = 0.000) and a ST-segment elevation in lead 1 (p = 0.005) were considered to be significant for Cx, and a ST-segment depression in lead I for RCA involvement (p=0.010). According to correspondence analysis, the most frequent single-vessel involvement seen in inferior AM] was RCA; when IRA was RCA, a multi-vessel involvement included RCA and Cx; and when IRA was Cx, a single-vessel involvement included the left anterior descending (LAD) artery most frequently, and RCA+LAD less frequently (p = 0.000). In inferior AMI, RCA was the most common IRA; however, the possibility of multi-vessel disease is increased when Cx is found to be the IRA. In patients presenting with inferior AM], the presence of ST-depression in the leads aVL and V1-2 is a sensitive finding that indicates Cx stenosis rather than RCA stenosis and is not affected by coexisting other coronary artery involvements.Öğe Early and late advanced atrioventricular black in acute inferior myocardial infarction(Lippincott Williams & Wilkins, 1998) Altun, A; Özkan, B; Gürçagan, A; Kadi, H; Özçelik, F; Özbay, GBackground Advanced atrioventricular block is a frequent complication in patients with inferior acute myocardial infarction (AMI); in patients in hospital, it often occurs concurrently with other complications and is associated with high mortality, Very little information is available about early and late advanced atrioventricular block in inferior AMI, We hypothesized that the time of appearance of advanced atrioventricular block characterized by poor response to atropine requiring temporary pacemaker therapy may affect the prognosis of patients with inferior AMI. Methods We studied 51 patients with inferior AMI and advanced atrioventricular block characterized by poor response to atropine requiring temporary pacemaker therapy. According to pre-established electrocardiographic criteria and the time of appearance of the advanced atrioventricular block, patients were divided into two groups: an early block group consisting of 30 patients who developed advanced atrioventricular block during the first 24 h of inferior AMI, and a late block group consisting of 21 patients who developed advanced atrioventricular block after the first 24 h of chest pain. Results The groups were similar regarding age, coronary risk factors, frequency of right ventricular infarction, QRS score, atrial and ventricular rates, the time of return to first-degree atrioventricular block, cardiac arrhythmias, heart failure and mortality. The early advanced atrioventricular block group included a greater number of men than did the late group (P = 0.017). Conclusion These data suggest that the time of appearance of advanced atrioventricular block does not affect the prognosis of hospital patients with inferior AMI.

Between January 1999 and December 2001, of 867 patients who underwent angiography for the first time, 90 patients (24 women and 66 men), with occlusion in only I coronary artery participated in the study. Information regarding age, body mass index, sex, smoking, hypertension, diabetes mellitus, hyperlipidemia, preinfarction angina, and use of oral beta blockers and nitrates were recorded for all patients. The patients were separated into 2 groups in accordance with development of their coronary collateral circulation; those with insufficient (Rentrop 0, 1, and 2) and those with sufficient coronary collateral circulation. They were also divided into 3 groups on the basis of body mass index as follows: (1) 18.0-24.9 kg/m(2), (11) 25.0-29.9 kg/m(2), and (111) more than 30 kg/ml. In the obesity and overweight groups, hyperlipidemia, diabetes mellitus, and nitrate use were identified more frequently than in the other groups (p < 0.05). Use of oral nitrates more than 6 months before the myocardial infarction and existence of preinfarction angina affected collateral coronary vessel development in the positive direction (p=0.01, p = 0.03, respectively). There was no correlation between coronary artery disease and coronary collateral vessel development in the obese patients (p = 0.6). Although it has been shown that coronary collateral vessel development was affected negatively in obese patients with coronary artery disease, no statistical significance was identified.Öğe Heart failure during first inferior acute myocardial infarction(Lippincott Williams & Wilkins, 1999) Altun, A; Özçelik, F; Özkan, B; Özbay, GBackground Inferior acute myocardial infarctions (AMI) have better in-hospital prognosis than do anterior AMI. Authors of several studies reported that patients with inferior AMI complicated by atrioventricular block, concomitant precordial ST-segment depression and involvement of right ventricle have larger infarctions and a worse prognoses than do patients without these features. Objective To analyse the incidence, clinical course and in-hospital prognosis of patients with heart failure and first inferior AMI. Methods We analysed in 257 consecutive patients with first inferior AMI who had been admitted to the coronary care unit during January 1991 and March 1995. The clinical and electrocardiographic characteristics, as well as the morbidities and in-hospital mortalities, of groups of patients with and without heart failure during inferior AMI were compared. Results Symptoms and signs of heart failure were noted for 49 patients (19%). We found that patients who had suffered heart failure during inferior AMI were older (61.1 +/- 9.86 versus 58.78 +/- 1 0.58 years, P<0.05) than those who had not suffered heart failure. There was no significant difference between patients' sex, history of diabetes mellitus, hypertension, smoking status, thrombolytic therapy, involvement of right ventricle and QRS score for these two groups. We found a greater prevalence of ST-segment depression (ST-segment depression greater than or equal to 1 mV in more than one precordial lead with maximal ST-segment depression in leads V4-V6) of V4-V6 precordial leads (57 versus 26%, P=0.00002) and a lesser prevalence of no ST-segment depression (ST-segment depression <0.1 mV in each precordial lead; 14 versus 38%, P=0.001) among patients who had suffered heart failure. We found greater incidences of serious ventricular arrhythmias (53 versus 26, P=0.0002) and ventricular tachycardia-fibrillation (16 versus 7%, P=0.03) among patients who had suffered heart failure than we did among those who had not. Third-degree atrioventricular block was more often found in patients who had suffered heart failure (23 versus 12%, P=0.07) but this difference was not statistically significant. We found that the in-hospital mortality among patients who had suffered heart failure was much higher than that among those who had not (24.5 versus 3.8%, P=0.000001). Conclusion We found that heart failure occurs primarily in old patients, and in those with precordial ST-segment depression, especially in leads V4-V6. The patients who suffer heart failure have worse in-hospital prognosis due to serious ventricular arrhythmias and cardiogenic shock.

The etiology, severity, and prognosis of the ischemic stroke might be estimated with the level of the activation of the coagulation system. In this study, prothrombin F1+2 (F1+2), D-dimer, and fibrinogen levels were measured in patients with acute ischemic stroke with and without NVAF, and stroke severity was compared with these hemostatic parameters. Of 55 patients, 29 had sinus rhythm (group I), 26 had NVAF (group II); 20 healthy subjects (group III) were included in the study. Subtypes of cerebral infarction were classified. The patients underwent stroke severity, electrocardiography, echocardiography, cranial computed tomography, cervical duplex ultrasonography, and hemostatic parameter studies. In group II, F1+2 level (2.83 +/- 0.89) was significantly higher than in group I (2.33 +/- 0.80) and III (1.94 +/- 0.64) (p values: group I-II, 0.036; groups II-III, 0.001; groups I-III, 0.104). In group III, fibrinogen level (251.64 +/- 60.96) was significantly lower than that in groups I (347.97 +/- 111.49) and II (364.04 +/- 86.20) (p = 0.001). D-dimer was not significantly different between groups. In group I, lacunar syndrome (LACS), and in group II, partial and total anterior circulation syndrome (PACS + TAGS) were more common (p = 0.013, p = 0.001, respectively). In group II, Scandinavian Stroke Scale scores were lower than those in group I (group I = 45.2 +/- 14, group II = 35.4 +/- 18.9, p = 0.02). In conclusion, activation of coagulation, demonstrated by increment F1+2, is more abundant in the stroke patients with NVAF than in the stroke patients with sinus rhythm. Our results also showed that activation of the hemostatic system might be related to stroke subtype and stroke severity. It is suggested that the oral anticoagulation treatment as prophylaxis is important in the prevention of stroke in patients with NVAFÖğe Hyperosmolar hyperglycaemic nonketotic coma associated with acute myocardial infarction(Taylor & Francis Ltd, 2002) Yildiz, M; Gül, Ç; Özbay, GDiabetes mellitus is one of the most commonly associated diseases of patients suffering an acute myocardial infarction. Although the coexistence of acute myocardial infarction with other clinical manifestations of diabetes have been well described, extremely few data exists about the concomitant occurrence of hyperosmolar hyperglycaemic nonketotic coma and myocardial infarctions. This article presents three patients with this association and aimed to discuss the clinical course and treatment strategies of this rare condition.Öğe I-123 MIBG scintigraphy in the detection of amiodarone induced pulmonary toxicity(Springer-Verlag, 2001) Altun, GD; Altun, A; Salihoglu, YS; Sankaya, A; Özbay, G; Berkarda, S[Abstract Not Available]Öğe Incidental detection of a quadricuspid aortic valve by transesophageal echocardiography in a patient with ruptured mitral valve chorda(I C R Publishers, 2002) Akdemir, O; Sürücü, H; Özbay, GQuadricuspid aortic valve is a rare congenital cardiac abnormality which is frequently detected at necropsy or surgery. Here, a young, asymptomatic patient with mild aortic. and mitral regurgitations is described in whom a quadricuspid aortic valve was detected incidentally on transesophageal echocardiography performed initially to diagnose ruptured mitral chordae tendineae.Öğe Predictive value of admission electrocardiogram for multivessel disease in acute anterior and anterior-inferior myocardial infarction(Futura Publ Co, 2002) Kürüm, T; Öztekin, E; Özçelik, F; Eker, H; Türe, M; Özbay, GBackground: Our aim was to investigate the correlation between admission ECG and coronary angiography findings in terms of predicting the culprit vessel responsible for the infarct or multivessel disease in acute anterior or anterior-inferior myocardial infarction (AMI). Methods: We investigated 101 patients with a diagnosis of anterior AMI with or without ST-segment elevation or ST-segment depression in at least two leads in DII, III, aVF. The patients were classified as those with vessel involvement in the left anterior descending (LAD) coronary artery and patients with multivessel disease. Vessel involvement in LAD + circumflex artery (Cx) or LAD + right coronary artery (RCA) or LAD + Cx + RCA were considered as multivessel disease. Thus, (a) anterior AMI patients with reciprocal changes in inferior leads, (b) anterior AMI patients with inferior elevations, (c) all anterior AMI patients according to the ST-segment changes in the inferior region were analyzed according to the presence of LAD or multivesssel involvement. Results: Presence of ST-segment depression in aVL and V6 was significantly correlated with the presence of multivessel disease in anterior AMI patients with reciprocal changes in the inferior leads (P = 0.005 and P = 0.003, respectively). No statistically significant difference between the leads were detected in terms of ST-segment elevation in predicting vessel involvement in the two groups of anterior AMI patients with inferior elevations, When all the patients with anterior AMI were analyzed, the presence of ST-segment depression in leads aVL, V4, V5 and V6 were significantly associated with the presence of multivessel disease (P = 0.035, P = 0.010, P = 0.011, P = 0.001, respectively). Conclusions: The presence of ST-segmert depression in anterolateral leads in the admission ECG of anterior AMI patients with reciprocal changes in inferior leads was associated with multivessel disease.Öğe The prevalence of hereditary thrombophilia in the Trakya region of Turkey(Yonsei Univ College Medicine, 2000) Demir, M; Vural, Ö; Sunar, H; Altun, A; Yorulmaz, F; Özbay, GThe prevalences of deficiencies in antithrombin III (AT III), protein C (PC), protein S (PS) and in the activated protein C (APC) resistance in the thrombotic population of the Trakya region, Turkey were investigated. 37 patients with venous thrombosis (VT) and 17 patients with arterial thrombosis (ArT) were included in this study. The mean ages of the patients with VT and ArT were 46 years (range 20-70) and 38 years (range 32-40), respectively; The activity of AT III was measured by commercially available immuno-turbidimetric assay. The activities of PC and PS were determined by coagulometric assay. The APC resistance was measured using a modified APTT-based clotting assay. Among the VT patients, there were 2 cases (5.4%) with AT Ill, 5 (13.51%) with PC deficiency, 5 (13.51%) with PS deficiency and 2 (5.4%) with APC resistance. In the ArT patient group, there was 1 patient (5.88%) with AT III, 3 (17.64%) with PC deficiency, 1 (5.88%) with PS deficiency and no APC resistant patients, while there was one (2.08%) with PC deficiency and one (2.08%) with APC resistance in the control group (49 persons, mean age 41 years). The relative risk of thrombosis (odds ratio) was 1.7 in the deficiency of PC and 5.6 in the deficiency of PS. The data presented suggests that the prevalences of AT III, PC and PS deficiencies causing thrombophilia in the Trakya region of Turkey are higher than in other reported studies while the APC resistance is lower than in others. Further studies including more patients would be required to clarify these discrepancies.Öğe QT dispersion in hypothyroidism(Elsevier Sci Ireland Ltd, 1999) Altun, A; Altun, G; Özbay, GWe studied ten women (age: 40+/-12 years) with primary hypothyroidism. Baseline and after T4 treatment (euthyroid stage), all patients' resting ECGs were recorded. After T4 treatment, QTd (P=0.036), QTad (P=0.016), JTd (P=0.0001), JTad (P=0.005), Ted (P=0.036), QRS (P=0.046), QTcd (P=0.036), QTacd (P=0.028), JTcd (P=0.006), JTacd (P=0.016), Tecd (P=0.036) values shortened in patients with hypothyroidism. We found that regional inhomogeneity of ventricular repolarization in patients with hypothyroidism improves after T4 treatment. (C) 1999 Elsevier Science Ireland Ltd.

Methods and results - We studied 11 patients with dual-chamber pacemakers (DDD) and 11 patients, with ventricular inhibiting mode (VVI). All patients underwent Doppler echocardiography of the left ventricle. Atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), renin and aldosteron were measured. The LV was scanned for the presence of intracavitary flow during the isovolumic relaxation and isovolumic contraction period. The plasma levels of BNP and ANP were significantly lower in DDD mode than in VVI mode (56+/-32 pg/ml vs. 94+/-32 pg/ml, p=0.022 and 98+/-20 pg/ml vs. 134+/-17 pg/ml, p=0.042, respectively). There were no significant differences in the plasma level of renin or aldosteron. VVI mode versus DDD mode increased isovolumic relaxation flow time (129+/-41 vs. 111+/-36 sec, p = 0.020) and isovolumic relaxation flow velocity (50+/-4 vs. 37+/-2 cm/s, p=0.018). A strong relationship between blood ANP and BNP levels and IRF velocity was found in patients with a VVI pacemaker (r: 0.632, p: 0.028; r: 0.528, p: 0.024, respectively). Conclusion - VVI mode has a longer isovolumic relaxation time, isovolumic relaxation flow velocity and has higher ANP and BNP plasma levels than DDD mode. IRF resulting from asynergy and asynchrony in VVI mode pacemakers versus DDD mode pacemakers affects the plasma levels of ANP and BNP compared to renin and alclosteron.Öğe Right ventricular aneurysm complicating right ventricular infarction(Acta Cardiologica, 2001) Akdemir, O; Gül, Ç; Özbay, GRight ventricular (RV) involvement commonly occurs in patients with acute inferior myocardial infarction and is associated with high mortality and morbidity. RV dysfunction and dilatation commonly recover in survivors; chronic RV dyskinesia and failure are rare complications. This case report presents a patient in whom an isolated RV aneurysm complicates a RV involvement of acute inferior-posterior myocardial infarction.Öğe Specific tissue Doppler predictors of preserved systolic and diastolic left ventricular function after an acute anterior myocardial infarction(Japan Heart Journal, Second Dept Of Internal Med, 2003) Akdemir, O; Dagdeviren, B; Yildiz, M; Gül, Ç; Sürücü, H; Özbay, GThe degree of left ventricular (LV) dysfunction determines the outcome of patients suffering an acute anterior myocardial infarction (AAMI). Many recent studies have utilized tissue Doppler echocardiography (TDE) parameters in the assessment of LV function. We sought to investigate whether some variables easily obtained from TDE profiles of mitral annulus corners would predict a relatively preserved LV global function traditionally assessed with ejection fraction (EF) and deceleration time (DT), within the acute phase of AAMI Included were 50 consecutive patients with a first AAMI. Standard echocardiography and TDE of mitral annulus were performed within 36 hours of admission Pulsed wave sample volumes were set at the septal, lateral, anterior, and inferior corners of the mitral annulus. Preserved LV function was defined as an EF > 40% together with a DT greater than or equal to 140 ms and < 220 ms. An inferior annular systolic velocity of > 7.5 cm/s predicts preserved global left ventricular function with a sensitivity of 81% and specificity of 71%. An anterior mitral annular early diastolic velocity of > 8cm/s had a sensitivity of 69% and specificity of 85%. When these two velocities both exceed the limits above, such a combined index yielded a sensitivity of 69%, specificity of 94%, and an overall diagnostic accuracy of 86% for the estimation of preserved LV global function. The parameters derived from TDE profiles of inferior and anterior mitral annulus corners provide valuable information to predict preserved global left ventricular function during the early period of AAMI.Öğe Transient ST segment changes mimicking early repolarisation phenomenon in a patient with angina at rest -: Coronary artery spasm.(Bmj Publishing Group, 2001) Altun, A; Akdemir, O; Tath, E; Özbay, G[Abstract Not Available]
