A patient arrived at the emergency department 2 days after the development of "chest pressure" and "tightness" was treated with antacids thinking it was indigestion
His enzymes show a massive myocardial infarction (MI). Following angioplasty, the patient asks why so much muscle was damaged if only one vessel was blocked, the left circumflex. The nurse responds, A) "With any blockage in the heart, muscle damage always occurs." B) "If a major artery like the circumflex is occluded, the smaller vessels supplied by that vessel cannot restore the blood flow." C) "Since the circumflex artery supplies oxygenated blood flow to the posterior surface of the left ventricle, any amount of blockage will result in vital muscle tissue being lost." D) "When it comes to arteries in the heart, all vessels are equal, and any blockage causes a massive amount of damage that will not be restored."
