Narrow pulse pressure

Hello all , first off I am a 33yr old male 5'10" and 160lbs . I was just wondering and worrying about my pulse pressure (difference between systolic and diastolic). I feel fine and everything but have been worried about my pulse pressure. My typical bp readings are 115/85, 120/90 124/90, which is a pulse pressure of around 30 on average but sometimes the readings can be as close as 24 apart. It isn't like this all the time though, throughout the day it changes and can average from 40-60. Like I said I have no symptoms and wouldnt even know this if I didnt continuously check it. It has me worried about heart failure but most the things I read about that say that is backed up by a fast resting pulse of over 100. My average resting heart rate is about 60-64. Should I be concerned??? Thanks, Dennis
