Randomized Controlled Trial Comparative StudyTreatment with ezetimibe plus low-dose atorvastatin compared with higher-dose atorvastatin alone: is sufficient cholesterol-lowering enough to inhibit platelets?
We sought to test the platelet inhibitory and anti-inflammatory effects of a higher statin dosage compared with combined treatment with ezetimibe plus a low statin dose. ⋯ Platelet reactivity and a proinflammatory chemokine were reduced more by the higher atorvastatin dose than by ezetimibe plus low-dose atorvastatin. In patients with coronary artery disease, it might be important to combine ezetimibe with higher statin dosages to benefit from cholesterol-independent pleiotropic effects.

Endovascular treatment for superior vena cava occlusion or obstruction in a pediatric and young adult population: a 22-year experience.
The purpose of this research was to investigate the causes and symptoms of superior vena cava (SVC) obstruction or occlusion and report on the long-term results of transcatheter therapy. ⋯ Superior vena cava-related symptoms occur in only 50% of patients with hemodynamically significant SVC obstruction. Endovascular therapy is successful in relieving the stenosis and associated symptoms with good long-term results.

Randomized Controlled Trial Comparative StudyA randomized controlled trial of multi-slice coronary computed tomography for evaluation of acute chest pain.
This study sought to compare the safety, diagnostic efficacy, and efficiency of multi-slice computed tomography (MSCT) with standard diagnostic evaluation of low-risk acute chest pain patients. ⋯ Multi-slice computed tomographic coronary angiography can definitively establish or exclude coronary disease as the cause of chest pain. However, inability to determine the physiological significance of intermediate severity coronary lesions and cases with inadequate image quality are present limitations.

Controlled Clinical TrialVascular remodeling after "successful" repair of coarctation: impact of aortic arch geometry.
This study was designed to investigate the influence of aortic arch geometry on vascular remodeling after anatomically successful repair of coarctation of the aorta (CoA). ⋯ In young adult survivors of anatomically successful CoA repair, a gothic-type aortic arch with high H/W is associated with abnormal IMT, higher aortic stiffness index, and impaired arterial reactivity in the pre-CoA vasculature.
