Article Synopsis
- The study assesses the relationship between fractional flow reserve (FFR) and noninvasive ischemia tests in patients with serious coronary artery obstructions.
- A retrospective analysis of 96 patients found that all had ischemia, but only 52% showed FFR values at or below the critical threshold of 0.80.
- The results indicate no strong correlation between FFR measurements and noninvasive ischemia tests, questioning the reliability of FFR in these cases.
Background: The efficacy of pharmacological stents in decreasing the incidence of cardiac events is not homogeneous for all lesions or patient subgroups.
Objective: 1) To evaluate the late clinical evolution of patients submitted to pharmacological stent implantation in atherosclerotic lesions of the left anterior descending artery; 2) to identify, among the clinical, angiographic and intravascular ultrasonographic characteristics, the ones predictive of cardiac event risk.
Methods: From May 2002 to August 2005, 205 patients were treated with 236 pharmacological stent implants, guided by the intravascular US (IVUS).
