Reference no: EM133295020
Case Scenario
Explain what effect this cardiac event would have on the function of the left side of Brocks heart by answering the following questions.
1a) Describe the normal pathway of blood through the left side of the heart, beginning with the structures that deliver blood to that side of the heart, the characteristics of blood that enters the left side of the heart, the structures it moves through to leavethe left side of the heart, and where it goes to
1b) Myocardial infarction (heart attack) usually occurs due to a blockage in the coronary arteries that supply the heart muscle.List possible coronary arteries that may have been affected and define the structure of the heart they supply to.
1c) Stroke volume is directly influenced by the cardiac parameters known as preload and afterload. Define each of these factorsand explain how they reduce stroke volume
1d) Referring to the equation for cardiac output, explain how Brocks cardiac output would be affected and why
Case Scenario 2
Before discharge from hospital, Brock's nurse discusses some of the risk factors for myocardial infarction. In Brock's case, this includes his hypertension. The nurse also discusses with Brock the medications that have been prescribed to treat his hypertension including:
Diuretic
Beta-blocker
Question Two: Explain How does each drug work to lower blood pressure?
2a) Explain how a diuretic works (i.e., its mechanism of action) to lower blood pressure. Refer to the blood pressure equation (BP = CO x SVR) to assist with your explanation.
2b) Explain how beta-blockers work (i.e., its mechanism of action) to lower blood pressure. Using the blood pressure equation (BP = CO x SVR) to assist with your explanation.
