https://www.selleckchem.com/Proteasome.html Especially patients with complex, cyanotic disease, heart failure and arrhythmias require particular attention. Treatment in patients with cyanotic heart disease should be guided by the relative degree of desaturation compared with baseline and lactate levels rather than absolute oxygen saturation levels. Patients with right heart dilatation or dysfunction are potentially at increased risk of right heart failure as mechanical ventilation and acute respiratory distress syndrome can lead to increase in pulmonary arterial pressures.Percutaneous coronary intervention (PCI) continues to advance at pace with an ever-broadening indication. In this article we will review the recent technological advances in PCI that have enabled more complex coronary disease to be treated. The choice of revascularisation strategy must take into account the evidence-just because we can treat by PCI does not necessarily mean we should. When PCI is indicated, a safe, precision PCI approach guided by physiology, imaging and optimal lesion preparation should be the goal to obtain complete revascularisation and a durable long-term result. When these standards are adhered to, the outcomes can be excellent, in even complex coronary disease. We provide contemporary trial evidence to justify PCI and treatment algorithms that ensure optimal revascularisation decision making to achieve the best patient outcomes.Objective Right ventricular (RV) function is a major determinant of survival in patients with pulmonary arterial hypertension (PAH). Metabolic alterations may precede haemodynamic and clinical deterioration. Increased RV fluorodeoxyglucose (FDG) uptake in positron emission tomography (PET) was recently associated with progressive RV dysfunction in MRI, but the prognostic value of their combination has not been established. Methods Twenty-six clinically stable patients with PAH (49.9±15.2 years) and 12 healthy subjects (control group, 44.7±13.5 years) h
