Casting a wider net to catch more cases of pulmonary hypertension

When most people think of high blood pressure, they think of being tested with an arm cuff at a doctor's appointment. That type of blood pressure is separate from pulmonary hypertension (PH), which is high blood pressure in the lung arteries. In a study published today in The Lancet Respiratory Medicine, investigators from Brigham and Women's Hospital took an evidence-based approach to determine the lower end of the risk spectrum for PH based on pulmonary vascular resistance (PVR), which is resistance against blood flow from the pulmonary artery to the lungs. The team presents evidence that by redefining the lower risk level for PVR, 60 percent more patients who are at risk for death due to PH can be diagnosed.
