Hyperkinetic PMI correlates to?

Hyperkinetic PMI correlates to?

• A. Increase in Stroke Volume; Does Not Indicate Cardiovascular Disease
• B. Decreased Stroke Volume
• C. Reduced Preload
• D. Aortic Aneurysm

Answer: (A)

Hyperkinetic PMI signals a hyperdynamic circulation where the left ventricle is ejecting a larger stroke volume, producing a brisk, forceful impulse at the apex. This reflects increased cardiac output from states that raise stroke volume—such as anemia, fever, pregnancy, or hyperthyroidism—rather than intrinsic heart disease. So the best match is an increase in stroke volume, and this finding does not by itself indicate cardiovascular disease. In contrast, decreased stroke volume would yield a softer impulse, reduced preload can blunt or alter the impulse but not make it hyperkinetic, and an aortic aneurysm involves vascular pathology with different exam cues rather than a brisk PMI.
