Percutaneous coronary intervention (PCI) is commonly used for patients with coronary artery disease (CAD). However, the effects of chronic kidney disease (CKD) and hypertension (HT) on long-term outcomes in patients with stable CAD receiving PCI are still unclear. A total of 1,676 patients treated with PCI were prospectively enrolled and divided into 4 groups according to the presence or absence of HT or CKD. General characteristics, clinical medications, risk factors, angiographic findings, and long-term outcomes were analyzed. Patients with CKD had the highest rate of all-cause and cardiovascular (CV) mortality (both P < 0.01). Patients with CKD alone had the lowest event-free rate of all-cause and CV deaths (both P < 0.001). Based on Cox proportional hazard model, patients with CKD alone had the highest risk of all-cause death (HR:2.86, 95% CI:1.73-4.75) and CV death (HR: 3.57,95% CI:2.01-6.33); while patients with both CKD and HT had the highest risk of repeat PCI (HR: 1.42, 95% CI:1.09-1.85).We found that in stable CAD patients after undergoing PCI, those with CKD alone had the highest long-term mortality. Comorbid CKD appears to increase risk in patient with HT, whereas comorbid HT doesn't seem to increase risk in patients with CKD.
