Two-Decade Trends in the Prevalence of Atherosclerotic Risk Factors, Coronary Plaque Morphology, and Outcomes in Adults Aged ≤45 Years Undergoing Percutaneous Coronary Intervention.

Data are limited about the prevalence trends of risk factors, lesion morphology, and clinical outcomes of coronary artery disease in patients, aged ≤45 years, undergoing percutaneous coronary intervention (PCI), between the bare-metal stent (BMS; 1994 to 2002) and drug-eluting stent (DES; 2003 to 2012) eras. From the PCI database at the Cleveland Clinic, we identified 1,640 patients aged ≤45 years and without a history of coronary artery bypass grafting who underwent PCI from 1994 to 2012. There were 883 patients in the BMS era cohort with a mean follow-up period of 13.15 years and 757 in the DES era cohort with a mean follow-up of 5.02 years. The DES era had more obese (51.8% vs 44.7%, p <0.001) and diabetes (23.0% vs 19.5%, p = 0.09) patients. DES era patients had more B2/C lesions (74.0% vs 32.5%, p <0.001), more severe preprocedural stenosis (86.1 ± 12.9 vs 72.2 ± 21.3, p <0.001), and longer lesions (15.5 ± 9.9 vs 9.6 ± 6.8, p <0.001). No difference was observed in the 30-day mortality between the DES and BMS eras. Irrespective of era, diabetics had worse long-term mortality (19.4% vs 9.3%, p <0.001) compared with nondiabetics. Obese patients had similar long-term outcomes compared with nonobese patients. In conclusion, patients aged ≤45 years, who underwent a PCI procedure in the DES era had worse risk factor profiles, including obesity, compared with patients in the BMS era. They also had more complex lesions. Procedural and long-term outcomes of these patients have not changed between the 2 eras. Young diabetic patients have worse long-term outcomes compared with nondiabetics.

Risk of cerebrovascular events in patients with patent foramen ovale and intracardiac devices.

OBJECTIVES: This study investigated whether patients with patent foramen ovale (PFO) have an increased risk of stroke due to permanent pacemaker (PPM)/implantable cardioverter-defibrillator (ICD) implantation. BACKGROUND: Data are lacking on the risk of stroke in patients with PFO and implantable intracardiac devices, either a PPM or an ICD. We investigated whether patients with PFO have increased risk of stroke due to PPM/ICD implantation. METHODS: Between 2001 and 2008, 2,921 consecutive patients with PFO (67.5 ± 16.4 years of age, 52.2% male) were identified from our echocardiography database. These patients were divided into a device group (patients had PPM/ICD implantation for any reason after receiving a diagnosis of PFO) and a no device group (patients did not have PPM or ICD implantation). Patients who had PFO closure during follow-up were excluded. Both groups were matched for baseline characteristics and medications. The incidence of ischemic stroke was assessed in each group after propensity score matching (case:control ratio of 1:1 yielding 231 pairs). All patients completed at least 4 years of follow-up until May 2012. RESULTS: There were 2,690 patients in the n device group (67.3 ± 16.4 years of age, 51.6% male) and 231 patients in the device group (75.4 ± 14.6 years of age, 59.3% male). Six patients (2.6%) in the no device group and 6 (2.6%) in the device group had a stroke during the follow-up period. No difference in the rate of stroke, transient ischemic stroke, or stroke/transient ischemic stroke was observed between the 2 groups. CONCLUSIONS: The risk of stroke in patients with PFO and an implantable intracardiac device is similar to those without an intracardiac device. In patients with PFO, without a history of stroke, device implantation might not be considered a risk factor for future stroke occurrence.
