The science as understood today is clear—stent placement to relieve symptoms of angina in patients with stable coronary artery disease does not reduce the risk of myocardial infarction when compared with optimal medical therapy. But a new, small study finds this information is not successfully communicated to patients. It found that most patients with stable coronary disease, all of whom went through the informed consent process with their cardiologists, still believe percutaneous coronary intervention (PCI) will reduce their myocardial infarction risk. The findings also suggest that a significant percentage of cardiologists believe stenting lowers myocardial infarction risk in this population.
