Latest Coronary artery bypass surgery Stories
Heart failure is a leading cause of death in Canada. As part of the ongoing IMPACT-CABG clinical trial to treat advanced heart failure, physicians at the Peter Munk Cardiac Centre performed the first cardiac stem cell transplant in Ontario last week using stem cells derived from the patient's own bone marrow, isolated completely within the operating room, and implanted into the heart at the time of coronary bypass surgery.
Patients who discontinued use of an antiplatelet agent such as clopidogrel prior to undergoing cardiac surgery to lower their bleeding risk and received intravenously the platelet inhibitor cangrelor achieved a higher rate of maintenance of platelet inhibition, compared to patients who received placebo.

Contrary to current guidelines, Mayo Clinic researchers have found that elective or primary (in patients who have had heart attacks) angioplasties performed at centers without on-site cardiac surgery capabilities pose no increased risk for patient death or emergency bypass surgery.
Despite current guidelines discouraging percutaneous coronary interventions (PCI; procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) being performed at centers without on-site cardiac surgery capability, an analysis of previous studies finds that PCIs at these centers are not associated with a higher incidence of in-hospital death or emergency coronary artery bypass surgery compared to PCIs at centers with on-site surgery.
Physician preferences and hospital characteristics influence the type of procedures performed on blockages of the heart, leading to significant variations in rates of bypass, stent or angioplasty procedures.
A new method for measuring narrowing in the arteries of the heart may allow patients to be assessed for a stent without having to take a drug with unpleasant side effects.
