BACKGROUND The aim of our study was to determine if ablation and pacing improved brain perfusion (BP) and cognitive function (CF) in patients with medically refractory rapidly conducted atrial fibrillation (Med Refr RCAF). METHODS AND RESULTS The study included 17 patients with Med Refr RCAF (average age 55.3 ± 4.5 years). All patients underwent brain(More)
Thirty-five cardiomyoplasty procedures were performed in five patients with dilated and 30 patients with ischemic cardiomyopathies. Russian-made cardiomyostimulators (CMS) were implanted in these patients. Twenty-one patients underwent a one-step procedure using a left thoracotomy for cardiomyoplasty, while in 14 patients, a two-step procedure that included(More)
The study included 31 patients with essential hypertension. Twenty-four hours blood pressure monitoring, assessment of neurological status and cognitive functions as well as single photon emission tomography were performed at baseline and three months after treatment. The beta-blocker therapy during 3 months exerted a positive effect on the brain perfusion(More)
AIM To compare antianginal efficacy and tolerability of propranolol therapy in patients with stable angina pectoris and chronic hypotension (Hpts) and normotensive patients with angina of effort (Npts). MATERIAL AND METHODS A randomized, single-blind, placebo-controlled study was made in 35 Hpts and 38 Npts was made using bicycle exercise tests,(More)
Scintigraphy of the myocardium with 199Tl-chloride was performed in 59 patients. On the basis of the results of clinicoinstrumental investigation the diagnosis of chronic CHD was made in 36, that of acute myocardial infarction--in 7. The control group consisted of 16 persons without signs of coronary pathology. The sensitivity of scintigraphy with(More)
Epy influence of combined treatment including neoadjuvant chemotherapy, radical surgery and intraoperative radiotherapy with a single dose of 15 Gr or 10 Gr has been studied in conditions of radiosensibilization on morphological and functional status of myocardium in non-small lung cancer patients at stage III with by means of ECG-synchronized single-photon(More)
Purpose: to study the feasibility of using the new radiopharmaceutical based on the technetium-99m-labeled gamma-alumina for identification of sentinel lymph nodes (SLNs) in breast cancer patients. The study included two groups of breast cancer patients who underwent single photon emission computed tomography (SPECT) and intraoperaive gamma probe(More)
AIM To assess in a randomized open study effect of 12-15 week use of angiotensin converting enzyme inhibitors (ACEI) with and without trimetazidine on myocardial perfusion reserve in patients with ischemic heart disease (IHD) and/or hypertension associated with type II diabetes. MATERIAL Patients (n=69) receiving long term ACEI therapy with transient(More)
OBJECTIVE The aim of this study was to evaluate cognitive function, as measured by serial neuropsychological testing, and cerebral perfusion, as measured by brain SPECT scanning in patients with coronary artery diseases (CAD) following off-pump and on-pump coronary artery bypass graft surgery. Besides, the relationship between cerebral blood flow, cognitive(More)
