Question

Which of the following is NOT a determinant of myocardial oxygen supply?

A) Hemoglobin level
B) Afterload
C) Blood oxygen saturation
D) Coronary blood flow
E) Diastolic time

Answer 1

Hemoglobin level is not a determinant of myocardial oxygen supply.

Step-by-step explanation:

Out of the options given, Hemoglobin level is NOT a determinant of myocardial oxygen supply.

Myocardial oxygen supply is primarily determined by factors such as coronary blood flow, blood oxygen saturation, and diastolic time.

For example, if there is a decrease in coronary blood flow or blood oxygen saturation, the myocardial oxygen supply may be compromised, leading to ischemia.
Hence, Hemoglobin level is not a determinant of myocardial oxygen supply.
