Usefulness of dual imaging stress echocardiography for the diagnosis of coronary allograft vasculopathy in heart transplant recipients.

Background: Coronary allograft vasculopathy (CAV) is the main factor limiting long-term survival after cardiac transplantation. Dual imaging stress echocardiography with wall motion and Doppler-derived coronary flow reserve (CRF) of the left anterior descending artery (LAD) is a state-of-the-art methodology during dipyridamole stress echocardiography (DiSE). This study involving 74 heart transplanted patients has the purpose to assess the diagnostic value of dipyridamole stress echocardiography with evaluation of wall motion (WM) and Doppler-derived coronary flow reserve for the diagnosis of coronary allograft vasculopathy.

Real incidence of diabetes mellitus in a coronary disease population.

The high prevalence of unknown diabetes mellitus (DM) in patients with coronary disease and that the oral glucose tolerance test (OGTT) is the best diagnostic method in this context are well known. However, data about the incidence of DM in this population have not been well described. In the present study, we sought to determine the actual incidence of new-onset DM in patients with coronary disease using the OGTT.

Cardiogenic shock following administration of propofol and fentanyl in a healthy woman: a case report.

Introduction: Cardiogenic shock is very uncommon in healthy people. The differential diagnosis for patients with acute heart failure in previously healthy hearts includes acute myocardial infarction and myocarditis. However, many drugs can also depress myocardial function.
