What is the normal systolic and diastolic pressure range in the aorta?

• A. 100-140 mmHg (systolic); 60-90 mmHg (diastolic)
• B. 120-160 mmHg (systolic); 70-100 mmHg (diastolic)
• C. 90-120 mmHg (systolic); 50-70 mmHg (diastolic)
• D. 140-180 mmHg (systolic); 90-110 mmHg (diastolic)

Answer: (A)

Normal pressures in the aorta reflect the systemic arterial pressure during a cardiac cycle. The peak systolic pressure produced by the left ventricle is typically about 100–140 mmHg, and the diastolic pressure maintained between beats is about 60–90 mmHg. This range provides adequate perfusion to organs, including the coronary arteries, while avoiding excessive aortic wall stress. Values outside this range—either higher or lower—are not normal central aortic pressures in a healthy adult. Therefore, 100–140 mmHg systolic with 60–90 mmHg diastolic best fits normal central aortic pressure.
