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)
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)
Time of appearance of agitated saline contrast in the left atrium is one of the distinguishing features between intracardiac and intrapulmonary shunt. We report a patient with hepatic cirrhosis who had intrapulmonary shunting and had appearance of peripheral venous saline contrast injection in the left heart chambers within 3 cardiac cycles after its(More)
OBJECTIVES We examined the hypothesis that mitral annulus calcification (MAC), aortic valve sclerosis (AVS) and aortic root calcification (ARC) are associated with coronary artery disease (CAD) in subjects age < or =65 years. BACKGROUND Mitral annulus calcification, AVS and ARC frequently coexist and are associated with coronary risk factors and CAD in(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)
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)
End of life is an unfortunate but inevitable phase of the heart failure patients' journey. It is often preceded by a stage in the progression of heart failure defined as advanced heart failure, and characterised by poor quality of life and frequent hospitalisations. In clinical practice, the efficacy of treatments for advanced heart failure is often(More)
Several new oral anticoagulants have been approved for thromboembolism prevention in patients with nonvalvular atrial fibrillation. However, they are not yet approved for anticoagulation use in patients with prosthetic mechanical valves, and no randomized data have been published so far on their safety of use in these patients. We present two cases of(More)
BACKGROUND Failure of ST-segment resolution (STR) after primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction is associated with adverse outcome but currently cannot be predicted on admission. Our aim was to determine whether failure of STR can be predicted from clinical and electrocardiographic data available on admission(More)
