I had a dissection at 4.5cm. I had only known about my aneurism for a year. It was 4 cm when discovered. I have been told not to lift, push, or pull anything that would cause me to hold my breath, strain, grunt, anything like that. Remember I have had the surgery. After surgery my BP were what they considered a little high. After 6 months they added Metropol by 1/2 tablet and said they wanted my BP below 120/80. I didn't have high BP before but since I had surgery they didn't want it in the 130's or higher. I have been doing well. I hope this helps you. Best wishes.
