UCSF researchers investigating the appropriate use of procedures to open narrowed coronary arteries -- such as angioplasty and stenting -- found that less than half of Medicare patients had documented noninvasive stress testing prior to elective percutaneous coronary intervention, or PCI, the clinical name for such procedures.
