Thoracic ascending aneurysm increase in size:
We have learned over the last five years that there are lifestyle modifications you can do to minimize risk of growth. Maybe the most important are keeping your blood pressure below 120/80; not lifting over 30 lbs; minimizing stress. Your weight limit may be lower given how much smaller you are than my husband.
