Re: Pulse Pressure 60 to 65 - Why?
Wide pulse pressure can be due to many causes:
hyperthyroidism - thyroid hormone potentiates norepinephrine action leading to increased cardiac contracility which increases systolic pressure, more than diastolic
Increased cardiac output seen in essential hypertension - often in part from elevated sympathetic nervous system outflow.
Pheochromocytoma - the catecholamines produced by the tumor yield an effect similar to the items above
Reduced vascular compliance - stiff vessels do not have normal elastance, thus systolic elevates abnormally with each stroke volume delivered to the aorta, and lack of recoil of the aorta in diastole produces a lower diastolic pressure.
Aortic Regurgitation - aortic valve regurgitation can produce profoundly elevated systolic pressure and quite low diastolic pressures. Your ECHO was normal so this isnt your case.
Your pulse pressures are perhaps somewhat elevated above that of a normtensive, but I dont think this is an unusual pulse pressure given that you are a young, hypertensive.
