Medications specifically used to treat pulmonary hypertension include epoprostenol, treprostinil, iloprost, bosentan, ambrisentan, macitentan, and sildenafil, tadalafil, selexipag, riociguat. [4] Lung transplantation may be an option in severe cases. [6] The frequency of occurrence is estimated at 1,000 new cases per year in the United States.
A pulmonary artery wedge pressure being less than 15 mmHg (also measured by right heart catheterization) excludes post-capillary bed (in the veins distal to the capillary bed) pulmonary hypertension. Pulmonary arterial hypertension is a subgroup of pulmonary hypertension and is categorized as World Health Organization as group 1. [3]
Pulmonology (/ ˌ p ʌ l m ə ˈ n ɒ l ə dʒ i /, / ˌ p ʊ l m ə ˈ n ɒ l ə dʒ i /, from Latin pulmō, -ōnis "lung" and the Greek suffix -λογία-logía "study of"), pneumology (/ n ʊ ˈ m ɒ l ə dʒ i, n j ʊ-/, built on Greek πνεύμων pneúmōn "lung") or pneumonology [1] (/ n ʊ m ə n ˈ ɒ l ə dʒ i, n j ʊ-/) is a medical specialty that deals with diseases involving ...
A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy. Examples include those branches of medicine that deal exclusively with children ( pediatrics ), cancer ( oncology ), laboratory medicine ( pathology ), or primary care ( family medicine ).
Respiratory therapists educate, assist in diagnosis, and treat people who have heart and lung problems. Specialized in both cardiac and pulmonary care, respiratory therapists often collaborate with specialists in pulmonology and anaesthesia in various aspects of clinical care of patients.
Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .
Similar to hypertensive retinopathy, evidence of nerve fiber infarcts due to ischemia (cotton-wool spots) can be seen on physical exam. Symptoms may include headache, nausea , or vomiting . Chest pain may occur due to increased workload on the heart resulting in inadequate delivery of oxygen to meet the heart muscle's metabolic needs .
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
