The Significance of Thallium-201-Chloride SPECT Myocardial Perfusion Imaging in the Management of Patients With Stable Chronic Coronary Artery Disease.

Background: Patients with stable coronary artery disease (CAD) can be evaluated for myocardial viability by examining reverse redistribution of Thallium-201 (TI) through cardiac scintigraphy. There is limited knowledge about association of a reverse redistribution with favorable cardiac outcomes. In this study, we hypothesized that higher left ventricular ejection fraction (LVEF), lower myocardial necrosis, fewer ischemic events, and less angina will be associated with reverse redistribution of TI imaging.

Arterial stiffness in patients with coronary artery disease: relation with in-stent restenosis following percutaneous coronary intervention.

Background: Coronary artery disease (CAD) is one of the most important issues in modern medicine due to its high mortality and prevalence. An early detection and prevention can reduce morbidity and mortality. Arterial stiffness is a potent and independent predictor of CAD.

Multiple multilateral coronary-cameral fistulae in a patient with minor cardiac venous system.

A 40-year-old man was hospitalized in the coronary care unit with chest pain and abnormal electrocardiogram. Twenty days earlier, the patient underwent laparoscopic gallbladder surgery. Due to chest pain and ischemic ECG changes, patient was subjected to coronary angiography.

Prevention of contrast-induced nephropathy with Na/K citrate.

Aims: Contrast-induced nephropathy (CIN) is a frequent complication of many radiological procedures involving the application of contrast media. It represents a significant health problem that causes the increase in mortality, morbidity, and medical costs. For the prevention of CIN, a number of methods have been proposed to be effective.

Measuring of the heparin leakage into the circulation from central venous catheters--an in vivo study.

Background: A catheter lock with a highly concentrated heparin solution is often used to maintain its patency. The result of the in vitro study shows a significant catheter leakage that occurs after locking the catheter. The goal of this study is to develop a model to measure the catheter leakage in vivo and test it on various kinds of catheters.
