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?

One of the reasons, a person during initial stages of atherosclerotic coronary blood vessel may not show any symptoms of cardiac dysfunction because 1. Coronary blood vessels show marked reactive hyperemia. 2. Coronary blood vessels carry large amount oxygen which is not fully used by myocardium 3. The threshold for activation of the pain fibers associated with the Coronary blood vessels does not occur until they are fully compressed by the disease. 4. None of the above is correct
