Comparative StudyPredicting the Need for Upfront Combination Therapy in Pulmonary Arterial Hypertension.
Combination therapy is commonly used for pulmonary arterial hypertension (PAH) treatment. We aimed to identify factors that may predict the need for future combination therapy. ⋯ Patients with PAH who require combination therapy in the course of their disease have worse hemodynamics, PAH risk score, functional class, and end of 6MWT oxygen saturation at the time of presentation compared to patients maintained on monotherapy.

Randomized Controlled Trial Comparative StudyNicorandil Versus Nitroglycerin for Symptomatic Relief of Angina in Patients With Slow Coronary Flow Phenomenon: A Randomized Clinical Trial.
Patients with the coronary slow flow phenomenon frequently experience angina episodes. The present study aimed to compare the efficacy of nicorandil versus nitroglycerin for alleviation of angina symptoms in slow flow patients. ⋯ In slow flow patients, nicorandil provides better symptomatic relief of angina than nitroglycerin.

ReviewWhat is Wrong With Cardiac Conditioning? We May be Shooting at Moving Targets.
Early recanalization of the occluded culprit coronary artery clearly reduces infarct size in both animal models and patients and improves clinical outcomes. Unfortunately, reperfusion can seldom be accomplished before some myocardium infarcts. As a result there has been an intensive search for interventions that will make the heart resistant to infarction so that reperfusion could salvage more myocardium. ⋯ In remote conditioning, a limb is subjected to ischemia/reperfusion prior to or during coronary reperfusion. Its mechanism is not as well understood as that of ischemic preconditioning, but the results have been very encouraging. In the present article, we will review ischemic, remote, and pharmacologic conditioning and possible confounders that could interfere with their efficacy in clinical trials in 2 settings of myocardial ischemia: (1) primary angioplasty in acute myocardial infarction and (2) elective angioplasty.

Meta Analysis Comparative StudyGenotype-Guided Dosing of Coumarin Anticoagulants: A Meta-analysis of Randomized Controlled Trials.
Coumarin anticoagulants (acenocoumarol, phenprocoumon, and warfarin) are generally used for the prevention of stroke in patients with atrial fibrillation or for the therapy and prevention of venous thromboembolism. However, the safe use of coumarin anticoagulants is restricted by a narrow therapeutic window and large interindividual dosing variations. Some studies found that the effectiveness and safety of coumarin anticoagulants therapy were increased by pharmacogenetic-guided dosing algorithms, while others found no significant effect of genotype-guided therapy. ⋯ This meta-analysis showed that genotype-guided dosing increased the effectiveness and safety of coumarin therapy compared with standard dosing but did not have advantages compared with clinical variables-guided dosing.
