Is diastolic pressure different from end-diastolic pressure?

Hi, I am a bit confused with some terminology...is diastolic pressure different to end-diastolic pressure? My understanding is that diastolic pressure refers only to the pressure in the aorta during ventricular relaxation whereas end-diastolic pressure refers to the pressure in the ventricles at the end of filling? Is this correct?

HI, thanks for using healthcare magic

Diastole is the period of time when the heart relaxes and fills with blood after systole (contraction).

End diastolic pressure refers to pressure in the ventricles at the end of diastole usually measured in the left ventricle as an approximation of end diastolic volume.

Diastolic pressure is lowest pressure in the arterial blood system occurring during each heart beat.

I hope this helps

My mom s blood pressure is currently 123 over 62. Is it dangerous to have such a large delta between systolic and diastolic? She is also experiencing intense pain on her left side, no tightness in her chest or lightheadedness though. Her father had many strokes and heart attacks before he died.

I recently have been noticing a Low diastolic blood pressure, I am 32? I am a 31 year old male. In excellent shape, 170 lbs 5 11 - I have unexplained hypertention. I have been on 40mgs of accupril for most of 9 years. I recently went to a cardiologist for an annual check up and received a echo and stress test, check for LVH and other cardiac issues. All results were normal. My blood pressure usually reads 125/80 w/ medication but recently I have been seeing lower diastolic pressures 125/65. My doctor added a diuretic to my treatment last year and I have stoped weight lifting which my cardiologist suggested might not be good for a hypertensive. Since then I have been running on average 8- 10 miles a week. Like i said my last cardio echo was perfect,.....could all this cardio and running be lowering my diastolic? If not what could it be if my echo s are clean ?
