HPR was defined as a PRU \u2265 200 during clopidogrel therapy.

Of these, 1789 tests had a PRU \u2265 200 (HPR overall prevalence, 54%). We then identified 1195 patients who underwent either an endovascular or coronary procedure and had a PRU measurement. This corresponded to 935 coronary and 260 endovascular interventions. In the coronary cohort, the HPR prevalence was 54% (503\/935). In the vascular cohort, the HPR prevalence was 53% (137\/260); there was no difference between cohorts in HPR prevalence ( p = 0.78).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\u201cClopidogrel resistance\u201d or HPR was found to be present in nearly half of patients with cardiovascular disease undergoing intervention. Our data suggest HPR is more common in the cardiovascular patient population than previously appreciated. Evaluating patients for HPR is both inexpensive ($25) and rapid (&lt; 10\u00a0min). Future randomized studies are warranted to determine whether HPR has a clinically detectable effect on revascularization outcomes.<\/jats:p>\n
