Rationale: New therapies for refractory angina are needed.
Objective: Assessment of transendocardial delivery of bone marrow CD133 cells in patients with refractory angina.
Methods And Results: Randomized, double-blinded, placebo-controlled trial enrolled 31 patients with recurrent Canadian Cardiovascular Society II-IV angina, despite optimal medical therapy, ≥1 myocardial segment with inducible ischemia in Tc-99m SPECT who underwent bone marrow biopsy and were allocated to cells (n=16) or placebo (n=15).
Background: Occurrence of a stroke is a major concern in patients undergoing coronary artery bypass grafting (CABG). It remains uncertain whether significant asymptomatic carotid artery stenosis (CAS) is associated with stroke incidence in such patients.
Aim: To investigate the incidence of cerebrovascular events, myocardial infarction (MI), and death in patients with a significant asymptomatic CAS undergoing CABG.
There is some evidence that deaf children are more threatened than the general population by dangerous heart arrhythmias. An example is Jervell-Lange-Nielsen syndrome (one of the forms of long QT syndrome) which is characterised primarily by congenital deafness and prolongation of the QT interval. The aim of this study was to perform preliminary cardiological examinations on 162 deaf children (76 girls and 86 boys, 3-15 years old, mean age 10.
