Question

After arriving at the ER, Leo was put on an iv and was administered nitroglycerin to cause coronary blood vessel dilation.  Blood also was drawn for a series of tests including creatine kinase (CK or CK-MB) and troponins (sometimes referred to as cTnT & cTnI) levels.  Results from these tests would later confirm an MI.  Leo then was wheeled to the cardiac catherization lab where coronary angiography was performed with the following results:
       Circumflex artery - 20% blocked
       Right coronary artery - 15% blocked
       Left anterior descending artery (or anterior interventricular artery) - 80 % blocked

Given the results of the angiogram, what part of his heart's muscle most likely was involved in the myocardial infarction?  Explain your reasoning.
