Compared with medical therapy, percutaneous coronary intervention (PCI) does not confer a mortality benefit or decrease myocardial infarction in stable angina. Therefore, PCI should be a patient-preference sensitive decision, guided by anginal symptoms. In reality, physicians may use other criteria to decide on whether to perform PCI.
We retrospectively reviewed charts of patients undergoing elective catheterization in 2 time periods (Dec 2007 to Aug 2008 and Jan 2012 to Jul 2012). We compared symptoms, stress test results and angiographic lesions of patients whose obstructive stenoses were treated with PCI to those with stenoses treated with optimal medical therapy (OMT).
Of the 446 patients, 96 had no CAD; 265 had obstructive stenoses >70%; 164 underwent PCI, 56 underwent CABG and 45 patients with lesions amenable to PCI were referred to OMT. Compared to patients who received OMT, those receiving PCI were younger, more likely to have non-C lesions and less likely to have a positive stress test or distal lesions. There were no differences in sex, race, symptoms, referral status or time period (Table 1).
For patients undergoing catheterization for chronic stable angina, the decision to proceed to PCI is associated with angiographic characteristics but not symptomatology.
