Demographic and clinical characteristics angiographic findings of Turkish patients with coronary artery fistula have been investigated in this study diagnostic tests treatment methods used these also evaluated detail.We examined the cardiac catheterization laboratory database retrospectively between March 2006 July 2010. Among 49,567 patients, we noted 60 diagnosed as fistula. After images were by two invasive cardiologists, 54 who had clear evidence vessel origin drainage included study.A...
An attenuated heart rate recovery (HRR) immediately after exercise has been shown to be predictive of mortality. It is not known whether HRR predicts mortality when measured in patients with failure. The present study was undertaken evaluate the ability predict We studied 84 NYHA class II or III chronic congestive failure who had a left ventricular ejection fraction < = 40%. All underwent symptom limited cardiopulmonary testing. value for defined as difference between peak and one-minute...
Paraoxonase 1 (PON1) is an organophosphate ester hydrolase associated with high-density lipoprotein (HDL). The recently emphasized function of PON1 activity its antiatherogenic activity. always found together HDL in plasma, and responsible for the protective effect against low-density (LDL) oxidation. Considering this role cardiovascular diseases antioxidant properties, may be a valuable biomarker predicting coronary artery ectasia (CAE), whose pathogenesis has not yet been fully elucidated....
Left atrial (LA) function is associated with left ventricular (LV) diastolic filling and cardiac output response to exercise. But the relation between LA exercise performance has not been adequately evaluated. The aim of this study was investigate capacity in dilated cardiomyopathy (DCM) cardiopulmonary testing. Forty-four patients a end-diastolic dimension (LVDd) > or = 60 mm an ejection fraction (EF) < 40%, normal sinus rhythm were included study. Patients divided into group 1 2 according...
<i>Background/Aims:</i> The timing of GpIIb/IIIa inhibitor administration may be important in achieving early epicardial and myocardial reperfusion. We evaluated the effect tirofiban on salvage cardiovascular outcome patients with acute infarction (AMI) undergoing infarct-related artery stenting. <i>Methods:</i> Patients (n = 66) a first AMI presenting <6 h from onset symptoms were randomized to either emergency room 32) or later catheterization laboratory 34)...
Low T3 which is defined as decreased triiodothyronine (T3) and normal thyroid-stimulating hormone (TSH) thyroxin (T4) levels present in many acute diseases related to increased mortality. We studied low level's relation long-term mortality non-ST-elevation coronary syndrome (NSTE-ACS) patients.T3, T4, TSH of consecutive NSTE-ACS patients were measured. Patients with T4 levels, but level group. T3, Clinical laboratory findings these two groups compared. In addition, we examined early...
Recent studies suggest that an increase in red cell distribution width (RDW) levels have a better prognostic value than single measurement. In the current study, we investigated predictive of increasing RDW for mortality acute pulmonary emboli (APE) patients.For 199 APE patients who were hospitalized enrolled. Patients divided into three groups according to their admission and 24th hour values. whom both values normal put group 1 (normal); with > 14.5% decreased 2 (decreased); whose >14.5%...
Background . An increased risk of ischemic stroke has been reported in patients with Parkinson’s disease (PD). Atrial fibrillation (AF) is strongly associated stroke. Prolonged atrial electromechanical delay (EMD) an independent predictor for the development AF. Aims The aim present study was to evaluate conduction parameters PD and assess their relation severity PD. Study design We prospectively enrolled 51 consecutive newly diagnosed 31 age- sex-matched non-PD subjects. Methods To coupling...
The relationship between the frequency of autonomic dysfunction (AD) and severity chronic obstructive pulmonary disease (COPD) has not been exactly known, despite its importance in pathogenesis COPD. Therefore, we aimed to evaluate clinical stage AD COPD patients.The type were determined according 35 stable patients. results compared mild moderate-severe groups. Sympathetic system (SS) was evaluated with sympathetic skin response (SSR), QT QTc intervals (ms) analyses. Parasympathetic heart...
Nitric oxide plays an important role in the regulation of basal vascular tone and cardiac myocyte function. We investigated NOS3-786T>C polymorphism chronic heart failure (CHF) its effects on long-term mortality.Ninety-one patients with CHF who were referred to Department Cardiology Siyami Ersek Cardiovascular Thoracic Surgery Center for cardiopulmonary exercise testing between April 2001 January 2004 30 controls enrolled this study. Patient followed prospectively a period 1 12...
<i>Background:</i> Little is known about the relationship between exercise intolerance and lipid peroxidation in chronic heart failure (CHF) patients. This study was designed to investigate exercise-induced plasma malondialdehyde (MDA) changes CHF patients determine whether there any association MDA levels capacity assessed by cardiopulmonary testing. <i>Methods:</i> Cardiopulmonary testing applied 31 (16 ischemic, 15 idiopathic) controls. Rest peak blood samples were...
Background: Red cell distribution width (RDW) is a quantitative measurement and shows heterogeneity of red blood size in peripheral blood. RDW has recently been associated with cardiovascular events diseases, it novel predictor mortality. In this study, we aimed to evaluate the clinical usefulness measuring patients coronary stent thrombosis. Patients methods: We retrospectively reviewed 3,925 consecutive who presented acute syndrome underwent angiography at Siyami Ersek Hospital between May...
The renin-angiotensin system has a very important role in coronary thrombosis and restenosis. Plasma angiotensin converting enzyme (ACE) activity is associated with an insertion/deletion polymorphism the gene coding for ACE. It known that there strong correlation between ACE DD atherosclerosis. However, little been documented about its venous graft failure. objective of this study was to investigate relationships among gen long-term vein occlusion.The population consisted 87 consecutive...
A single coronary artery with an anomalous origin between the pulmonary and aorta is unusual congenital anomaly. We present a 60 year old female patient stable angina pectoris. Her angiogram revealed that right originated from left main stem coursed great vessels. There was 90% stenosis in anterior descending artery. performed fractional flow reserve study of both stenosed vessel. Fractional RCA did not reveal functional ischemia. refer to bypass grafting but instead percutaneous...
The efficacy of angiotensin-converting enzyme (ACE) inhibitors in the treatment heart failure (HF) is well documented. However, ACE may provide incomplete blockade renin-angiotensin-aldosterone system due to alternative pathways for production angiotensin II (Ang II). aim this study was evaluate combined therapy an inhibitor and Ang receptor blocker losartan patients with HF by using cardiopulmonary exercise testing (CPET) on a treadmill.Seventeen (ejection fraction < or = 40%) were included...
