That finding held true for patients with several severely blocked coronary arteries. The study, she added, “certainly will challenge our clinical thinking.”This is far from the first study to suggest that stents and bypass are overused. Nor did those trials include today’s improved stents, which secrete drugs intended to prevent opened arteries from closing again. With its size and rigorous design, the new study, called Ischemia, was intended to settle questions about the benefits of stents and bypass. Instead, the patients had narrowed arteries that were discovered with exercise stress tests.
