From: A dynamical model for heart remodeling during the two phases of pulmonary arterial hypertension

Fig. 6

Evolutions of the different variables of our model when the mean pulmonary arterial pressure is progressively increased: mean pulmonary arterial pressure (a, b), heart rate (a), mean aortic pressure (b), right and left backflow resistances (c) and right and left end-diastolic volumes (d). The graph can be divided into 4 phases: the first phase (from day 0 to day 530) corresponds to the phase without any pulmonary arterial hypertension (P pa<25 mmHg), the second phase (from day 530 to day 1128) is the compensation phase, the third phase (from day 1128 to day 2315) is the decompensation phase. The last part (from day 2315) corresponds to the “death zone” during which the patient can no longer survive
