Erythrocyte membrane, plasma and atherosclerotic plaque lipid pattern in coronary heart disease.

The objective was to analyze the lipid composition of the atherosclerotic plaque (AP), plasma and erythrocyte membrane (EM) in patients with advanced coronary heart disease (CHD). AP were obtained through endarterectomy in 18 patients. Ten normolipemic healthy subjects were selected to obtain the normal lipid pattern profile.

Recommendations for use of everolimus after heart transplantation: results from a Latin-American Consensus Meeting.

Despite improvements during the last decades, heart transplantation remains associated with several medical complications, which limit clinical outcomes: acute rejection with hemodynamic compromise, cytomegalovirus (CMV) infections, allograft vasculopathy, chronic renal failure, and neoplasias. Everolimus, a proliferation signal inhibitor, represents a new option for adjunctive immunosuppressive therapy. Everolimus displays better efficacy in de novo heart transplant patients than azathioprine for prophylaxis of biopsy-proven acute rejection episodes of at least ISHLT grade 3A (P < .

Methylene blue reduces mortality and morbidity in vasoplegic patients after cardiac surgery.

Background: The discovery of nitric oxide as mediator in cardiac postoperative vasoplegia encourages the use of inhibitory drugs such as methylene blue. This drug has been used with favorable results in isolated cases. The purpose of this article is to analyze the incidence of the postoperative vasoplegic syndrome, to consider its prognosis, and to evaluate the effect of intravenous methylene blue on mortality.

Amrinone stimulation test: ability to predict improvement in left ventricular ejection fraction after coronary bypass surgery in patients with poor baseline left ventricular function.

Objectives: This study sought to determine whether the response to amrinone in patients with severe baseline left ventricular dysfunction can predict improvement in left ventricular ejection fraction after coronary artery bypass graft surgery.

Background: Previous studies have suggested that the inotropic response to dobutamine can identify viable myocardium in the setting of chronic coronary disease and left ventricular dysfunction. However, increased oxygen demand stimulated by dobutamine can lead to superimposition of ischemia on the hibernating state, potentially confounding interpretation of results.

Argentine randomized trial of percutaneous transluminal coronary angioplasty versus coronary artery bypass surgery in multivessel disease (ERACI): in-hospital results and 1-year follow-up. ERACI Group.

Objectives: This study was designed to compare freedom from combined cardiac events (death, angina, myocardial infarction) at 1-, 3- and 5-year follow-up in patients with multivessel disease randomized to either percutaneous transluminal coronary angioplasty or coronary artery bypass graft surgery.

Background: Percutaneous transluminal coronary angioplasty has been an effective approach in patients with coronary artery disease, but its role in patients with multivessel coronary artery disease is still controversial.

Methods: One-hundred twenty-seven patients with multivessel disease and lesions suitable for either form of therapy were randomized to either coronary artery bypass grafting (n = 64) or coronary angioplasty (n = 63).
