A patient presents with severe heart failure and BP 90/60 mmHg with underlying severe aortic stenosis and EF 33%. His cardiac index is 1.8 l/min/m².
What is the drug that will optimally improve his myocardial performance?
- High dose dopamine (15 μg/kg/min)
This patient has a high peripheral vascular resistance despite his low systemic pressure. All vasoconstrictors will decrease myocardial performance, which will negate the effect of the added B1 effect with high dose dopamine and norepinephrine.
