Although different groups of PH have different etiologies, pulmonary vascular dysfunction is common in these groups. PH can lead to increased pulmonary artery pressure, which can …

Since right ventricle is dependent on preload, RV contractility and afterload, severe pulmonary arterial hypertension causes pathological changes to right ventricle

Jan 6, 2023 · Pulmonary hypertension is increased pressure in the pulmonary circulation. It has many secondary causes; some cases are idiopathic. Pulmonary vessels may become …

Nov 15, 2019 · Increases in pulmonary vasculature pressures cause both diastolic and systolic dysfunction of the right ventricle. The resulting preload-dependent output of the right ventricle …

Feb 21, 2022 · In these patients, pulmonary vasodilators may precipitate cardiogenic pulmonary edema by increasing blood flow through the right ventricle and hence increasing left ventricular …

Jan 1, 2024 · Right heart failure may manifest from derangements in preload, afterload (such as pulmonary hypertension), or intrinsic myocardial dysfunction (such as myocardial infarction), …

Chronic PH causes adaptation and remodelling of the RV to increased loading conditions.

Pulmonary hypertension (PH or PHTN) is a condition of increased blood pressure in the arteries of the lungs. [7] Symptoms include shortness of breath, fainting, tiredness, chest pain, swelling …

Jan 31, 2023 · Pulmonary hypertension (PH) is a pathophysiological disorder that may involve multiple clinical conditions and can complicate many cardiovascular and respiratory diseases …

Jan 12, 2022 · Often multiple causes of PH co-exist and identifying potentially multiple factors that are contributing is necessary for optimal management.
