When the heart is at risk, patients are eager to listen to their doctor's recommendations. But three studies have found that many cardiologists oversell the benefits of percutaneous coronary interventions involving stenting, and patients often fail to remember the doctor's precautions about the procedure. JAMA Internal Medicine found that many patients with chronic angina are pushed onto the PCI path and don't ask if the treatment will actually help their particular case. For example, patients with stable angina do not often benefit from PCI surgery, although the treatment was found to be offered to them regardless. If the treatment was explained as ineffective for a patient's case, more than 30% of them still continued to believe it might help them. Story
