Question of the Day
Which of the following changes would MOST likely result in increased coronary artery perfusion in a patient with aortic stenosis?
Explanation
Coronary perfusion pressure is the major determinant of coronary artery perfusion and is equivalent to the aortic diastolic pressure minus the left ventricular end-diastolic pressure (LVEDP). An increase in systemic vascular resistance leads to increased aortic diastolic pressure. Thus, an increase in systemic vascular resistance would be likely to elicit an increase in coronary artery perfusion.
