Randomized Controlled Trial
A randomized study of the relative pharmacokinetics, pharmacodynamics, and safety of alirocumab, a fully human monoclonal antibody to PCSK9, after single subcutaneous administration at three different injection sites in healthy subjects.
We investigated the relative pharmacokinetics, pharmacodynamics, and safety of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab following injection at three different sites. ⋯ These results suggest that alirocumab can be interchangeably injected in the abdomen, upper arm, or thigh.

Randomized Controlled Trial Multicenter Study Comparative Study
Real polymer-free sirolimus- and probucol-eluting versus biodegradable polymer sirolimus-eluting stents for obstructive coronary artery disease: DKPLUS-Wave 1, a multicenter, randomized, prospective trial.
Polymer-free sirolimus- and probucol-eluting stents (Real Dual drug-eluting stents [DES]) is as effective as first-generation DES in treating coronary artery stenosis. It is unknown whether sirolimus-eluting stents containing biodegradable polymer (Excel) would be superior to real Dual DES. This study aimed to investigate the difference in target vessel revascularization (TVR) at 12 months in patients with coronary artery disease treated by the implantation of Dual DES or Excel stents. ⋯ The Excel stent was statistically superior to the Dual DES in terms of restenosis, late loss, and TVR for long lesions.

Randomized Controlled Trial
The effect of prethrombolytic cyclosporine-A injection on clinical outcome of acute anterior ST-elevation myocardial infarction.
Reperfusion injury reduces the benefits of early reperfusion therapies after acute ST-elevation myocardial infarction (STEMI). Cyclosporine-A (CsA) is a potent inhibitor of opening of the mitochondrial permeability transition pore, which has been shown to play a key role in myocardial reperfusion injury. The impact of this treatment on clinical outcomes of acute STEMI remains unknown. Our aim was to investigate the clinical outcomes of using this drug in patients with acute anterior STEMI receiving thrombolytic treatment (TLT). ⋯ In this study, the prethrombolytic administration of CsA was not associated with a reduction in the infarct size or any improvement in clinical outcomes.

Randomized Controlled Trial
Cardiac shock wave therapy for chronic refractory angina pectoris. A prospective placebo-controlled randomized trial.
Cardiac shock wave therapy (CSWT) delivered to the myocardium increases capillary density and regional myocardial blood flow in animal experiments. In addition, nonenzymatic nitric oxide production and the upregulation of vascular growth factor's mRNA by CSWT have been described. The aim of the study was therefore to test its potential to relieve symptoms in patients with chronic stable angina pectoris. ⋯ This placebo controlled trial shows a significant improvement in symptoms, quality of life parameters and ischemic threshold during exercise in patients with chronic refractory angina pectoris treated with CSWT. Thus, CSWT represents a new option for the treatment of patients with refractory AP.

Randomized Controlled Trial
A dosing algorithm for erythropoietin alpha in older adults with heart failure and a preserved ejection fraction.
Erythropoietin stimulating agents (ESAs) is an active area of clinical investigation in heart failure (HF) but can cause hypertension and higher hemoglobin concentrations (Hb) that have been associated with adverse outcomes. We evaluated a dosing algorithm and potential confounders' effect on Hb and blood pressure (BP) in a clinical trial. ⋯ The currently employed dosing algorithm, which adjusts the administration of ESA based on the absolute hemoglobin and weekly change in hemoglobin increases Hb with relatively a low weekly dose of ESA without significant effects on BP.
