Outcomes After Percutaneous Coronary Intervention in Patients With a History of Cerebrovascular Disease: Insights From the Blue Cross Blue Shield of Michigan Cardiovascular Consortium.
CIRCULATION-CARDIOVASCULAR INTERVENTIONS(2018)
摘要
Background-Because of shared risk factors between coronary artery disease and cerebrovascular disease, patients with a history of transient ischemic attack (TIA) or stroke are at greater risk of developing coronary artery disease, which may require percutaneous coronary intervention (PCI). However, there remains a paucity of research examining outcomes after PCI in these patients. Methods and Results-We analyzed consecutive patients who underwent PCI between January 1, 2013, and March 31, 2016, at 47 Michigan hospitals and identified those with a history of TIA/stroke. We used propensity score matching to adjust for differences in baseline characteristics and compared in-hospital outcomes between patients with and without a history of TIA/stroke. We compared rates of 90-day readmission and long-term mortality in a subset of patients. Among 98730 patients who underwent PCI, 10915 had a history of TIA/stroke. After matching (n=10618 per group), a history of TIA/stroke was associated with an increased risk of in-hospital stroke (adjusted odds ratio, 2.04; 95% confidence interval, 1.41-2.96; P<0.001). There were no differences in the risks of other in-hospital outcomes. In a subset of patients with postdischarge data, a history of TIA/stroke was associated with increased risks of 90-day readmission (adjusted odds ratio, 1.22; 95% confidence interval, 1.09-1.38; P<0.001) and long-term mortality (hazard ratio, 1.23; 95% confidence interval, 1.07-1.43; P=0.005). Conclusions-A history of TIA/stroke was common in patients who underwent PCI and was associated with increased risks of in-hospital stroke, 90-day readmission, and long-term mortality. Given the devastating consequences of post-PCI stroke, patients with a history of TIA/stroke should be counseled on this increased risk before undergoing PCI.
