amedheadwould decreased cardiac output not also increase the blood pressure due to sympathetic activation of the baroreceptor reflex?+
bwdcI think youโre ignoring a directly correct answer, increased PVR literally equals increased BP, and are instead trying to postulate an indirectly plausible answer. Decreased CO, as you just implied, means less blood pumping into the aorta and less blood pounding and stretching the arteries and thus decreased BP. Note, your original logic would apply to stroke volume just as easily. Yes, a sympathetic response could then occur as a response to mitigate this, such as in shock or heart failure, but it would misleading to suggest that decreased CO causes hypertension.+3

The only thing that directly raises BP of the list is increased PVR.
