Background: There is limited data regarding the clinical utility of cystatin C in patients with stable coronary artery disease (CAD). The aim of this study was to determine the predictive value of cystatin C for the presence and severity of CAD and the association between this protein and other biochemical risk factors for atherosclerosis in patients with(More)
Limited, controversial data exist regarding changes in high-sensitivity C-reactive protein (hs-CRP) levels over short times and the importance of detecting these changes in patients who have coronary artery disease (CAD). We investigated the variation of hs-CRP levels and their association with the severity of CAD in patients with stable CAD.We measured(More)
Reactive oxygen species have been implicated in the pathogenesis of contrast-induced nephropathy (CIN). We investigated the relationship between CIN with paraoxonase 1 (PON-1) activity and oxidative stress markers (total antioxidant status [TAS], total oxidant status [TOS], and oxidative stress index [OSI]) in patients with anterior ST-segment elevation(More)
OBJECTIVE Some findings of left ventricular (LV) functions in athletes are controversial. On the other hand, studies concerning the right ventricle (RV) are limited. The aim of the study was to assess the effects of endurance training on LV and RV systolic and diastolic function. METHODS A total of 60 (54 male, 6 female) athletes (mean age 20.7 +/- 2.5(More)
We reported a 21-year-old patient with strict descending aorta coarctation and small post-ductal patent ductus arteriosus, complicated with abortion and hypertension. The patient was successfully treated by endovascular stent-graft with a single cardiac catheterization. Endovascular stent-graft is an easy, safe, and reliable intervention for the treatment(More)
Our aim was to investigate, in patients with heart failure, the relationship between left atrial size and exercise capacity and cardiovascular events. Seventy-five patients (67 men and 8 women; mean age, 53.4 +/- 8.8 yr) with left ventricular ejection fractions of < or =0.45 (New York Heart Association functional classes I-III) were matched by age and sex(More)
We investigated the effects of atorvastatin on inflammation and cardiac events during the inpatient period and initial 6-month follow-up in acute coronary syndrome (ACS) patients with low low-density lipoprotein (LDL) cholesterol level. One hundred and twelve consecutive ACS patients with LDL cholesterol less than 100 mg/dl were included in the study (mean(More)
The prognostic value of pulse pressure has been investigated in heart-failure patients. Low pulse pressure in advanced heart failure and high pulse pressure in mild heart failure have been separately linked to increased mortality rates. We prospectively investigated an association between pulse pressure and 2-year cardiovascular death in an entire(More)
Percutaneous device closure of atrial septal defect (ASD) is an alternative treatment to surgery. The main advantages of the percutaneous approach include avoidance of surgery, short procedure time and hospital length, in addition to comparable rates of complications. However, percutaneous device closure is associated with infrequent early and late(More)
OBJECTIVE Mean platelet volume (MPV) plays a pivotal role in the pathophysiology of atherosclerotic disease. Thoracic aortic intima-media thickness (IMT) was reported as an earlier marker of preclinical atherosclerosis than carotid IMT. However, the relationship between MPV and aortic IMT was not investigated. We aimed to assess the relationship between(More)
