1. Mr. Garcia had a myocardial infarction. Explain what happened to his heart muscle and vascular system. What is a STEMII? 2. Mr. Garcia's chest pain resolved after two sublingual NTF at 3-minute intervals and 2 mg of IV morphine. In the cardiac catheterization lab he was "found to have a totally occluded distal right coronary artery and a 70% occlusion in the left circumflex coronary artery. The left anterior descending artery was patent. Angioplasty of the distal right coronary artery resulted in a patent infarct- related artery with near normal flow. A stent was left in place to stabilize the patient and limit infarct size. Left ventricular ejection fraction was normal at 42%, and a posterobasilar scar was present with hypokinesis." a. Explain angioplasty and stent placement. Define occluded occlusion. b. What is the purpose of this medical procedure?
