Estado del arte en hipertensión pulmonar y cateterismo cardiaco derecho

Abstract

The universally accepted definition of pulmonary hypertension corresponds to all those patients with a mean pulmonary arterial pressure of equal to or greater than 25mm Hg at rest, measured using right-heart catheterisation. It should not be forgotten that the mean normal pulmonary arterial pressure is a maximum of 20mm Hg, which means that patients with a mean pulmonary arterial pressure between 20 and 24mm Hg need to be followed-up. It should also be remembered to be clear on differentiating between pulmonary hypertension and pulmonary arterial hypertension. Pulmonary hypertension includes five groups, among which pulmonary arterial hypertension is Group 1. The concept of exercise-induced pulmonary arterial hypertension can be defined as all those patients with a pulmonary arterial hypertension above 30mm Hg at a cardiac output less than 10 L, or a total pulmonary resistance of more than 3 Wood units. Exercise-induced pulmonary hypertension is a research field that has been little investigated up until now. The classification still has five groups, and is dynamic in accordance with the progress in understanding the pathophysiology of each disease.
