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)
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)
Background: Recently it has been demonstrated that transcutaneous delivery of ultrasound combined with tissue plasminogen activator (tPA) is more effective than tPA alone in recanalizing acutely thrombosed canine coronary arteries. In the present study, we investigated the incidence of partial (≥50%) and complete (≥70%) ST-segment elevation resolution in(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)
Ultrasound energy is currently being used and intensively investigated for recanalization of thrombotically occluded arteries. The ultrasonic energy is mainly applied either by a transcutaneous approach or by a percutaneous approach through a catheter with an external ultrasound transducer. Catheter-delivered transducer-tipped ultrasound thrombolysis is a(More)
