From: A dynamical model for heart remodeling during the two phases of pulmonary arterial hypertension
Evolution of the mean pulmonary arterial pressure P pa and the pulmonary resistance R p versus time as described by our model for reproducing the evolution of a pulmonary hypertension. The graph can be divided into 4 parts: the first part (from day 0 to day 530) corresponds to the phase without any pulmonary arterial hypertension (P pa<25 mmHg), the second part (from day 530 to day 1128) is the compensation phase, the third part (from day 1128 to day 2315) is the decompensation phase, and the last part (from day 2315) corresponds to the “death zone” during which a patient can not survive
