A small percentage of patients with COPD develop pulmonary hypertension with no other disease to explain the high pressure. [109] On the other hand, obesity-hypoventilation syndrome is very commonly associated with right heart failure due to pulmonary hypertension. [110]
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]
Since the main causes of right ventricular hypertrophy is tricuspid regurgitation or pulmonary hypertension (discussed above), management involves treatment of these conditions. [3] Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [ 12 ]
The most common presentations of hypertensive emergencies are cerebral infarction (24.5%), pulmonary edema (22.5%), hypertensive encephalopathy (16.3%), and congestive heart failure (12%). [5] Less common presentations include intracranial bleeding, aortic dissection, and pre-eclampsia or eclampsia. [6]
The treatment of acute respiratory failure may involve medication such as bronchodilators (for airways disease), [7] [8] antibiotics (for infections), glucocorticoids (for numerous causes), diuretics (for pulmonary oedema), amongst others. [1] [9] [10] Respiratory failure resulting from an overdose of opioids may be treated with the antidote ...
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
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 ...
Diabetes has several complications of which one is hypertension or high blood pressure. Data indicate that at least 60-80 percent of individuals whom develop diabetes will eventually develop high blood pressure. The high blood pressure is gradual at early stages and may take at least 10–15 years to fully develop.
