The three major determinants of myocardial oxygen demand (MVO2) include each of the following except: a. Diastolic pressure b. Heart rate c. Left ventricular contractility d. Systolic pressure Fill in the Blank: 2. is the most important factor in myocardial oxygen demand. As this increases, myocardial oxygen consumption or demand also increases. Multiple Choice: 3. What is the most common cause of cardiogenic shock? a. Heart failure b. Cardiomyopathy c. Myocardial infarction d. Hypertension Multiple Choice: 4. Which does NOT occur during cardiogenic shock? a. Decreased cardiac output b. Hypotension c. Hypoperfusion d. Decreased systemic vascular resistance Your Answer: Question 18 10 / 10 pts Explain the differences in the pathophysiology, symptoms, and whether nitroglycerin and/or rest will relieve symptoms in stable angina, unstable angina, and myocardial infarction. Your Answer: artherscloes disease cornary vessel become norrow and the blood supply to the diminish, with extertion vessel cant vasodilate, therefore PT feels pain in the chest and short breath , that is what stable angina is. stable angina the heart is at rest but cant keep up the demand extertion. stable angina typically 70% stenosis cornary artries, it can be relieve with rest or nitroglyclcerin unstable agina is with increase occlusion cornary vessel demand with heart at rest may become to the PT experience angina without extertion that is unstable angina. unstable angiona means one more cornary arties are nearly or totaly occluded res is unsufficeint but nitrogycycerin can releive myocardial infraction is cause by when plaque repture cornary thrombosis can cause complete the collrate flow is not the tissue supplied vessel become ischemd with oxygen and portion of the heart muscle can die that is the couse of MI. the symptoms of the heart attack are pain in the jow lefts side pain that can raidiate to the left hand nusea/vomating , shortness ofbreath crushin pain in the chest, women can feel fatigue, weekness, also GI complain, it canot be relieve with nitrglyclerin With atherosclerotic disease, the coronary vessel lumens are narrowed and blood supply to the heart is diminished. With exertion, the vessels cannot adequately vasodilate. This can manifest as chest pain or tightness and/or shortness of breath. Stable angina- The heart is stable at rest but cannot keep up with the demand of exertion. Stable angina typically has a 70% stenosis of the coronary arteries. It is relieved by rest or nitroglycerin (vasodilator). Unstable angina- With increasing occlusion of the coronary vessel(s), the demands of the resting heart may become too great. When the patient experiences angina without exertion, or when the level of exertion necessary to cause anginal symptoms decreases, this is called unstable angina. It can be relieved by nitroglycerin, but not rest. Unstable angina means one or more coronary vessels is nearly totally occluded. Myocardial infarction- If a plaque ruptures, coronary thrombosis can cause complete occlusion. If collateral flow is inadequate, the tissue supplied becomes ischemic. Without oxygen, a portion of the muscle can die. MI can present as chest pain unrelieved by rest, sometimes radiating down the left ram or into the jaw or neck, dyspnea, nausea/vomiting, sweating, and/or other signs of distress. Other symptoms include a crushing pain or like “something is sitting on my chest.” Women may present with weakness, fatigue, shortness of breath, or GI complaints. Symptoms are not relieved by nitroglycerin. Question 19 5 / 10 pts Question 20 2.5 / 2.5 pts Question 21 2.5 / 2.5 pts Question 22 2.5 / 2.5 pts Question 23 2.5 / 2.5 pts Multiple Choice: With atherosclerotic disease, the coronary vessel lumens are narrowed and blood supply to the heart is diminished. With exertion, the vessels cannot adequately vasodilate. This can manifest as chest pain or tightness and/or shortness of breath. What is this referred to as? Correct! Question 24 2.5 / 2.5 pts Correct! Question 25 2.5 / 2.5 pts Which arrhythmias are dangerous because of severely reduced diastolic time and cardiac output? Select all that apply. Correct! Correct!
