-Decrease the workload on the heart and promote maximum coronary artery filling.
Step-by-step explanation;
-A myocardial infarction (MI), also known as a heart attack, occurs when a portion of the heart is deprived of oxygen due to blockage of a coronary artery. Coronary arteries supply the heart muscle (myocardium) with oxygenated blood.
-An inferior myocardial infarction occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
