Previous studies have shown synergism between ultrasound and thrombolytic agents or microbubbles on blood clot dissolution. It has not been investigated whether heparin or glycoprotein IIb/IIIa blockers enhance clot lysis by ultrasound. We compared the blood clot dissolution effect of saline, heparin, tissue plasminogen activator (tPA), tirofiban, and an(More)
BACKGROUND Limitations of coronary thrombolysis include the time to reperfusion, patency rate, and bleeding. We evaluated the use of noninvasive transcutaneous ultrasound to augment coronary thrombolysis. METHODS AND RESULTS In 24 dogs, a thrombotic occlusion of the left anterior descending coronary artery was induced and documented by 12-lead ECG and(More)
This review aims to provide a synthesis of the published evidence regarding the rationale and clinical benefits of cardiac resynchronization therapy (CRT) with implantable atrial-synchronized biventricular pacing (BVP) devices in patients with moderate to advanced heart failure and intra- and interventricular conduction delays. In addition, it addresses(More)
We determined the effects of cyclooxygenase-1 (COX-1; SC-560), COX-2 (SC-58125), and inducible nitric oxide synthase (iNOS; 1400W) inhibitors on atorvastatin (ATV)-induced myocardial protection and whether iNOS mediates the ATV-induced increases in COX-2. Sprague-Dawley rats received 10 mg ATV.kg(-1).day(-1) added to drinking water or water alone for 3 days(More)
We assessed 1) whether pretreatment before ischemia with pioglitazone (Pio) limits infarct size (IS) and whether this protective effect is due to nitric oxide synthase (NOS) and/or prostaglandin production, as has been shown for atorvastatin (ATV); and 2) whether Pio and ATV have synergistic effects on myocardial protection. Sprague-Dawley rats received(More)
Kimura's disease (KD) is an angiolymphoid proliferative disorder of soft tissue with eosinophilia, with a predilection for head and neck regions in young Oriental men. Renal disease is rarely associated with it. We describe a young non-Oriental male with KD and relapsing steroid-responsive minimal-change nephrotic syndrome. This case of KD associated(More)
Purpose: Both ATV and SL reduce myocardial infarct size (IS) by enhancing expression and activity of NOS isoforms. We investigated whether atorvastatin (ATV) and sildenafil (SL) have synergistic effects on myocardial infarct size (IS) reduction and enhancing nitric oxide synthase (NOS) expression. Method: Rats were randomized to nine groups: ATV-1 (1(More)
STUDY OBJECTIVES The decrease in incidence of tuberculosis, along with the increase in invasive cardiovascular procedures, may have changed the frequency of causes of bloody pericardial effusion associated with cardiac tamponade, although this is not yet recognized by medical textbooks. We analyzed the causes of bloody pericardial effusion in the clinical(More)
The ischemic heart suffers from nutrient deprivation, lack of oxygen, metabolic acidosis, hyperkalemia and Ca(2+) overload as well as high level of reactive oxygen species (ROS) generation; these risk factors endanger the cardiomyoctes and may cause their demise. Nevertheless, the treatment of acute myocardial infarction includes reperfusion, although it(More)
