Observational Study
Superior long term outcome associated with native vessel versus graft vessel PCI following secondary PCI in patients with prior CABG.
Secondary percutaneous coronary intervention (PCI) in patients with prior coronary artery bypass graft surgery is increasingly common. Graft vessel PCI has higher rates of adverse events compared with native coronary vessel PCI. ⋯ Secondary PCI in patients with prior CABG surgery is increasingly common. Graft vessel PCI has inferior outcomes with high rates of restenosis and occlusion compared with native coronary vessel PCI. We studied the clinical outcomes of 220 patients with prior CABG who underwent secondary PCI to either a graft vessel (GV), a native coronary vessel (NV) or both graft and native (NG) vessels. Target vessel revascularisation was 5 times higher in the GV compared with the NV group. History of CRF and impaired left ventricular function were associated with higher risk of death. We also found that the median survival (interval between CABG and end of follow-up period) was better in the NV group compared with GV group. This registry study demonstrates inferior long term outcome for patients undergoing secondary PCI of GV. A strategy of NV rather than GV target PCI should be considered in patients with prior CABG.

Soluble urokinase plasminogen activator receptor (suPAR) has emerged as a relatively new biomarker that reflects increased inflammatory status and been associated with cardiovascular risk. We wanted to investigate the predictive value and usefulness of suPAR as an inflammatory biomarker in obese children. ⋯ Our research did not demonstrate the usefulness of suPAR as an inflammatory biomarker and a predictive value for future atherosclerosis in obese children. Further studies with larger sample size are required to determine whether suPAR is useful as an inflammatory biomarker in childhood obesity.

Pulmonary artery aneurysm (PAA) occurs in some patients with pulmonary arterial hypertension (PAH). We evaluated the characteristics of cardiac dysfunction in patients with PAH complicated by PAA. ⋯ In PAH patients with PAA, RV was larger and RV dysfunction was more severe, and LV diastolic dysfunction appeared. It is important to investigate the appearance of PAA and the severity of RV and LV dysfunction in PAH patients with PAA.

The aim of this study was to determine the prevalence of exercise-induced pulmonary hypertension (EIPH) in consecutive subjects referred for stress echocardiography for chest pain or shortness of breath and correlate echocardiographic diagnosis of EIPH with hemodynamics at right heart catheterization (RHC). ⋯ The results demonstrate that 11.7% of patients undergoing clinically indicated stress echocardiography have EIPH. Of those who underwent RHC abnormal hemodynamics were significantly associated with a dilated left atrium or age older than 55years.
