Questions: Question 10 of 15 A patient recently suffered a myocardial infarction. He has suffered from hypertension for the past 10 years. What is the proper sequence of events showing how the patient's hypertension may have played a role in his myocardial infarction? Increase workload on the heart Left ventricular hypertrophy Myocardial ischemia Inceased arterial blood pressure Myocardial infarction

The proper sequence of events showing how the patient's hypertension may have played a role in his myocardial infarction is as follows:

1. Increased arterial blood pressure
2. Increase workload on the heart
3. Left ventricular hypertrophy
4. Myocardial ischemia
5. Myocardial infarction

Explanation:

1. Increased arterial blood pressure: Hypertension leads to consistently high blood pressure in the arteries.
2. Increase workload on the heart: The heart has to work harder to pump blood against the higher pressure in the arteries.
3. Left ventricular hypertrophy: Over time, the increased workload causes the left ventricle to thicken and enlarge (hypertrophy) to cope with the increased demand.
4. Myocardial ischemia: The thickened heart muscle may not receive adequate blood supply, leading to reduced oxygen delivery to the heart tissue (ischemia).
5. Myocardial infarction: Prolonged ischemia can result in the death of heart muscle tissue, leading to a myocardial infarction (heart attack).

This sequence outlines the pathophysiological process linking chronic hypertension to the development of a myocardial infarction.
