702 Possible Causes for Pulmonary Artery Pressure Increased

  • High Altitude Pulmonary Hypertension

    .- Thirty-four mountaineers were studied at low (110 m) and high altitude (4559 m) to evaluate if increased pulmonary artery systolic pressure (PASP) at high altitude is associated[ncbi.nlm.nih.gov] Its vasodilatory effects effectively counteract the hypoxia-induced increase in pulmonary arterial pressure.[emedicine.medscape.com] OBJECTIVE: High altitude leads to an increase in sympathetic nervous system (SNS) activity and pulmonary arterial pressure (PAP).[ncbi.nlm.nih.gov]

  • Secondary Pulmonary Hypertension

    […] decrease pulmonary artery cross sectional area, increase pulmonary artery pressure, increase pulmonary artery blood floow What are examples sof diseases that decrease pulmonary[quizlet.com] Sildenafil did not affect aortic pressure, but it significantly decreased pulmonary artery pressure and increased cardiac index, thereby reducing pulmonary vascular resistance[ncbi.nlm.nih.gov] Furthermore, the addition of hypoxic pulmonary hypertension will increase pulmonary artery pressures and therefore the load on the right heart.[thorax.bmj.com]

  • Pulmonary Hypertension

    Pulmonary hypertension (PH) is an increase in pulmonary arterial pressure secondary to narrowing and obliteration of the lumen of the lung vessels resulting in an increased[ncbi.nlm.nih.gov] From Wikidata Jump to navigation Jump to search hypertension characterized by an increase of blood pressure in the pulmonary artery, pulmonary vein or pulmonary capillaries[wikidata.org] Signs and symptoms of pulmonary arterial hypertension occur when increased blood pressure cannot fully overcome the elevated resistance.[web.archive.org]

  • Cor Pulmonale

    Indeed, from a pathophysiologic and clinical standpoint, any disease in which pulmonary arterial pressures increase sufficiently to affect right ventricular function results[accessmedicine.mhmedical.com] An oxygen saturation of less than 85% usually causes pulmonary arterial pressure to increase above 25 mm Hg. Acidosis and exercise cause further elevations. 4.[rjoson.tripod.com] […] in afterload, the rv increases systolic pressure to keep the gradient. at a point, a further increase in the degree of pulmonary arterial pressure produces significant rv[allnurses.com]

  • Familial Pulmonary Arterial Hypertension

    As the vessels become narrowed, pulmonary arterial pressure increases, resulting in compensatory hypertrophy of the right ventricle.[arup.utah.edu] Pulmonary hypertension occurs when the mean arterial blood pressure in the pulmonary artery increases above 25 mmHg during rest (normal pressure: Pulmonary hypertension means[aoporphan.com] artery pressure increases because of increasing right ventricle work, thrombotic pulmonary arteriopathy occurs.[emedicine.medscape.com]

  • Pulmonary Arterial Hypertension

    Pulmonary hypertension occurs when the mean arterial blood pressure in the pulmonary artery increases above 25 mmHg during rest (normal pressure: Pulmonary hypertension means[aoporphan.com] What happens in the event of pulmonary hypertension (PAH)?[aoporphan.com]

  • Acute Cor Pulmonale

    Elevated pulmonary artery pressure increases right ventricular workload with resulting myocardial hypertrophy and diastolic dysfunction ultimately leading to diastolic right-heart[acphospitalist.org] Likewise, our study showed a significant increase in pulmonary artery pressures in patients with Mastora index values greater than 21.3% and a further significant increase[ajronline.org] Decreased luminal cross sectional diameter leads to increased resistance and increased pulmonary artery pressure. 8. 6.[slideshare.net]

  • Eisenmenger Syndrome

    They become stiff and hard and, as this process occurs, the pressure in the pulmonary arteries increases.[pulmonaryhypertensionrn.com] BACKGROUND: In Eisenmenger syndrome (ES), oral phosphodiesterase type-5 inhibitors, which are preferential pulmonary vasodilators, reduce the elevated pulmonary artery pressure[ncbi.nlm.nih.gov] One trial showed a significant effect of bosentan treatment over placebo on indexed pulmonary vascular resistance and mean pulmonary artery pressure, but a non-significant[ncbi.nlm.nih.gov]

  • High Altitude Pulmonary Edema

    At high altitude, systolic pulmonary artery pressure increased less in participants receiving dexamethasone (16 mm Hg [95% CI, 9 to 23 mm Hg]) and tadalafil (13 mm Hg [CI,[ncbi.nlm.nih.gov] As reported, at 4,559 m pulmonary arterial pressure was increased in healthy volunteers but reached higher levels in HAPE.[ncbi.nlm.nih.gov] Brief Summary: It has been shown, that subjects susceptible to high altitude pulmonary edema (HAPE)are characterized by an abnormal increase of pulmonary artery pressure at[clinicaltrials.gov]

  • Hypertension
