Abstract
PURPOSE OF REVIEW The endotracheal intubation of patients with pulmonary arterial hypertension (PAH) in respiratory distress is a highly morbid procedure that can precipitate hemodynamic collapse. Here we review our strategy for confronting this difficult clinical situation. RECENT FINDINGS There are no clinical trials that explore best practices in the management of patients with PAH and respiratory failure. Here we provide a practical approach to respiratory support, inopressor and pulmonary vasodilator selection, hemodynamic considerations, point-of-care ultrasound monitoring, and endotracheal intubation in patients with PAH in respiratory failure.

Abstract
The management of acute medical emergencies in patients with pulmonary hypertension (PH) can be challenging. Patients with preexisting PH can rapidly deteriorate due to right ventricular decompensation when faced with acute physiological challenges that would usually be considered low-risk scenarios. This review considers the assessment and management of acute medical emergencies in patients with PH, encompassing both pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH), acknowledging these comprise the more severe groups of PH. Management protocols are described in a systems-based approach. Respiratory emergencies include pulmonary embolism, airways disease, and pneumonia; cardiac emergencies including arrhythmia and chest pain with acute myocardial infarction are discussed, alongside PH-specific emergencies such as pulmonary artery dissection and extrinsic coronary artery compression by a dilated proximal pulmonary artery. Other emergencies including sepsis, severe gastroenteritis with dehydration, syncope, and liver failure are also considered. We propose management recommendations for medical emergencies based on available evidence, international guidelines, and expert consensus. We aim to provide advice to the specialist alongside the generalist, and emergency doctors, nurses, and acute physicians in nonspecialist centers. A multidisciplinary team approach is essential in the management of patients with PH, and communication with local and specialist PH centers is paramount. Close hemodynamic monitoring during medical emergencies in patients with preexisting PH is vital, with early referral to critical care recommended given the frequent deterioration and high mortality in this setting.

Abstract
Pulmonary hypertension due to left heart disease (PH-LHD) or group 2 PH is the most common and lethal form of PH, occurring secondary to left ventricular systolic or diastolic heart failure (HF), left-sided valvular diseases, and congenital abnormalities. It is subdivided into isolated postcapillary PH (IpcPH) and combined pre- and post-capillary PH (CpcPH), with the latter sharing many similarities with group 1 PH. CpcPH is associated with worse outcomes and increased morbidity and mortality when compared to IpcPH. Although IpcPH can be improved by treatment of the underlying LHD, CpcPH is an incurable disease for which no specific treatment exists, likely due to the lack of understanding of its underlying mechanisms. Furthermore, drugs approved for PAH are not recommended for group 2 PH, as they are either ineffective or even deleterious. With this major unmet medical need, a better understanding of mechanisms and the identification of effective treatment strategies for this deadly condition are urgently needed. This review presents relevant background of the molecular mechanisms underlying PH-LHD that could translate into innovative therapeutic targets and explores novel targets currently being evaluated in clinical trials.

Abstract
Pulmonary hypertension (PH) is a common diagnosis in patients admitted to the cardiac intensive care unit with a wide range of underlying causes. A detailed evaluation to identify all factors contributing to the elevated pulmonary artery pressure and provide an assessment of right ventricular haemodynamics and function is needed to guide treatment and identify patients at highest risk for poor outcomes. While in many patients management of underlying and triggering medical problems with careful monitoring is appropriate, a subset of patients may benefit from specialized treatments targeting the pulmonary circulation and support of the right ventricle. In such cases, collaboration with or transfer to a centre with special expertise in the management of PH may be warranted.

Abstract
PURPOSE OF REVIEW Need for intensive care in the patient with pulmonary arterial hypertension is associated with high mortality. This review will provide an overview of causes of ICU admission for patients with pulmonary hypertension and provide guidance on management. RECENT FINDINGS There is a paucity of evidence-based medical literature on management of patients with pulmonary arterial hypertension. This article will summarize the available literature and expert guidance on the topic. Patients with pulmonary arterial hypertension may require ICU care as a direct consequence of decompensated right heart failure. Alternatively, patients with pulmonary arterial hypertension may be affected by the myriad of maladies encountered every day in the ICU including acute respiratory failure, septic shock, and gastrointestinal bleeding. The treatment plan should focus on identifying and treating the cause for decompensation. In addition, optimization of right ventricular preload, reduction of right ventricular afterload, correction of hypotension and augmentation of right ventricular inotropy should be considered. SUMMARY The approach to ICU care of patients with pulmonary arterial hypertension requires special consideration with regard to intubation and mechanical ventilation and management of volume status and hemodynamics. Whenever possible, these patients should be transferred to centers with experience in treating this complex, vulnerable population.
