Heart failure (HF) is a growing medical problem and it is of interest to study new biomarkers for better characterisation. In this sense, nitric oxide, reactive oxygen species (ROS), NADPH, and superoxide dismutase (SOD) were evaluated, along with their possible predictive value in patients with HF. An analysis was also performed on the potential(More)
The efficiency of prophylactic antiarrhythmic treatment with amiodarone in reducing 1-year mortality in patients with reduced left ventricular ejection fraction ( < 35%) and asymptomatic ventricular arrhythmias (Lown classes 2 and 4) was investigated in a prospective, multicenter, randomized, controlled study. Among 127 patients who entered the study, 61(More)
An experimental model for dog sinoatrial node autoperfusion is proposed. A by-pass was performed between right internal mammary artery and right atrial dorsal artery. A blood flow of 2.5 +/- 0.15 ml/min was calculated from blood forward velocity measurements. The injection of either isoproterenol or verapamil into the by-pass was followed by rapid heart(More)
