If your doctor suspects that you have PH, he or she will want to review your medical and family history, perform a physical exam and perform one or more diagnostic tests. Patients have little chance of survival if the mean pulmonary artery pressure to pulmonary artery occlusion pressure gradient or transpulmonary gradient is higher … The increased pressure makes your heart work harder, which can cause symptoms of heart or lung problems. As a result, the blood pressure in these arteries -- called pulmonary arteries -- rises far above normal levels. Pulmonary hypertension, defined as a mean pulmonary arterial pressure greater than 25 mm Hg at rest or greater than 30 mm Hg during exercise, is often characterized by a progressive and sustained increase in pulmonary vascular resistance that eventually may lead to right ventricular failure. Patients who have PH secondary to a medical condition such as left heart failure, lung diseases, or thromboembolic disease (PH group 2, 3, and 4 respectively) should receive treatment for the underlying cause. The right side of the heart must work harder to pump blood, and may become enlarged over time. The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved ), however most of the time, the right ventricle adjusts to an overload in chronic pressure.According to Voelkel, et al., … Upload media Wikipedia: Instance of: disease: Subclass of: hypertension: Authority control Q1128595 National Diet Library ID: 001107142.

Pulmonary arterial hypertension is a progressive disorder characterized by abnormally high blood pressure (hypertension) in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs. PH is defined as an elevated mean pulmonary artery pressure (PAP) ≥ 25 mmHg as measured by right heart catheterization at rest. It falls under group 1.5 of the Dana Point classification system of pulmonary hypertension (2008). Blood pressure in veterinary patients is not measured routinely; therefore hypertension is usually only diagnosed after clinical signs become apparent.
