| Abstract | <p>For patients with acute myocardial infarction (MI), the immediate therapeutic goal is to establish the patency of the infarct-related artery. Prolonged myocardial ischemia, however, often breaks down the coronary microvasculature, and the flow to the infarct myocardium may be markedly reduced. This is called the no-reflow phenomenon. This phenomenon is important not solely because it correlates with infarct size but because it provides additional prognostic information. With recent advances in imaging modalities, the no-reflow phenomenon is observed more frequently than when clinical judgment alone is used. Patients with this phenomenon are associated with poor functional and clinical outcomes. Now, the no-reflow phenomenon can be a parameter with which to predict high-risk patients. The focus of reperfusion therapy has shifted toward the improvement of myocardial perfusion. The improvement of myocardial perfusion could promote the functional recovery of viable muscle and reduce infarct expansion, which is associated with favorable clinical outcomes. For this purpose, pharmacological interventions and catheter-based devices to retrieve embolic materials have been proposed. Advances in our understanding of the pathophysiology of microvascular dysfunction would aid the development of therapeutic strategies for its prevention and treatment.</p> |

| Abstract | Pulmonary arterial hypertension (PAH) is characterized by elevation of pulmonary artery pressure caused by pulmonary vasoconstriction and vascular remodeling, which leads to right heart failure and death. Epoprostenol (prostaglandin I2) has a potent short-acting vasodilator property, and intravenous continuous epoprostenol is therefore used for treatment of PAH. Here we review evidence for the usefulness of intravenous continuous epoprostenol therapy in patients with PAH. Epoprostenol therapy is effective in idiopathic PAH patients and in patients with PAH associated with connective tissue disease, portal hypertension or congenital heart diseases, but it is not effective in patients with pulmonary veno-occlusive disease or pulmonary capillary hemangiomatosis. High-dose epoprostenol therapy markedly improved hemodynamics in some patients with PAH, possibly due to reverse remodeling of pulmonary arteries. This therapy has several side effects and complications such as headache, hypotension and catheter-related infections. Intravenous continuous epoprostenol is an effective treatment, but there are still some problems to be resolved. |

| Abstract | A treatment strategy for patients with pulmonary hypertension (PH) and atrial septal defect (ASD) remains unclear. This study was designed to evaluate the effects of initial repair of ASD followed by treatment with PH-specific drugs in patients with PH and ASD. Eligible patients receive transcatheter ASD closure followed by treatment with bosentan and sildenafil. Right heart catheterization is performed at baseline and at 12, 24 and 48 weeks. The primary endpoint is change in pulmonary artery pressure and pulmonary vascular resistance from baseline to follow-up. This study should provide valuable information to establish a therapeutic strategy for PH and ASD. |
