Embodiments disclosed herein establish relationships between changes in cardiovascular indicators and drug combinations. These relationships are established by tracking causal chains described by linear relationships, from drug combinations to cardiovascular parameters and from cardiovascular parameters to cardiovascular indicators, by measuring the direction and sensitivity of hemodynamic changes caused by changes in cardiovascular parameters (resulting from drug administration). Some embodiments also model myocardial oxygen consumption, which cannot be directly measured, and establish relationships between hemodynamic changes in myocardial oxygen consumption and changes in one or more cardiovascular parameters. Because these embodiments qualitatively and quantitatively establish causal chains from drugs to cardiovascular indicators, they support clinical decision-making, thereby reducing the level of mere guesswork and uncertainty in determining the optimal drug combination for patients with acute heart failure.
