pulmonary vascular resistance definition

Results: Death attributed to PAH occurred in six out of these 18 patients (33.3%, 7% of total cohort).Patients with precapillary PH and "borderline" PVR falling outside the current definition have adverse outcomes.

The final dataset included 284 SSc patients, 146 patients (49.2%) had mean pulmonary arterial pressure (mPAP) ≤20 mm Hg, 19.3% had mPAP 21-24 mm Hg and 29.4% had mPAP ≥25 mm Hg.

Using the Australian and New Zealand Pulmonary Hypertension Registry, we aimed to study a population diagnosed with PAH between January 2004 and December 2017 with the pre-defined haemodynamic characteristics of mean PAP ≥25 mmHg, PAWP ≤15 mmHg and PVR <3 Wood units.Eighty-two patients met the pre-defined haemodynamic inclusion criteria (mean age 63±11 years; 67 females).

The normal PVR is usually less than 2 Wood units (between 30 and 180 dynes/sec/cm −5).PVR is increased by anything that causes increased resistance in the pulmonary vascular system, including pulmonary emboli, hypoxia, and so on. Use of pulmonary arterial hypertension-specific therapy in overweight or obese patients with obstructive sleep apnea and pulmonary hypertension.  |  Pulmonary vascular resistance occurs when the pulmonary artery creates resistance against the blood flowing into it from the right ventricle.The resistance is naturally created by the arrangement of blood vessels in the lungs and is healthy in low levels. However, this abnormal elevation of mPAP is not sufficient to define pulmonary vascular disease as it can be due to an increase in cardiac output or pulmonary arterial wedge pressure.
