Aorta measurements

I am 59 male 205 lbs 5'9".  CAT scan findings are:: The chest wall anatomy and lungs are unremarkable. There are small mediastinal lymph nodes, which are not pathologic by size criteria.
The pericardium is unremarkable. The central pulmonary artery is
unremarkable. The cardiac chambers have normal dimensions. There is
normal central venous and pulmonary venous return. The coronary sinus is
unremarkable. There are mild, partially calcified atherosclerotic changes
of the coronary arteries. However, the current study is not optimized for
coronary assessment.
The aortic valve is trileaflet, without evidence of leaflet
calcification. The aortic root has normal dimensions. The sinotubular
junction is maintained, without evidence of calcification. There is
prominence of the ascending thoracic aorta, without evidence of
arthrosclerotic changes. The aortic arch has normal dimensions. The arch
branch vessels are patent without evidence of atherosclerotic changes.
There are trivial calcification of the proximal descending thoracic
aorta. The descending thoracic aorta has normal dimensions, without
evidence of arthrosclerotic changes. The aorta is seen to the level of
the right renal artery. There is no evidence of aortic dissection.
The aortic annulus measures 2.1 x 2.5 cm. The aortic root measures 3.6
cm at the sinuses of Valsalva. The sinotubular junction measures 3.4 cm.
The aorta measures 4.0 cm in the mid-ascending segment, 3.6 cm proximal
arch, 2.8 cm isthmus, and 2.6 cm mid-descending thoracic aorta.
IMPRESSION: Normal-size aortic root (3.6 cm) with maintained sinotubular
junction.
Prominence of the ascending thoracic aorta (4.0 cm).

I workout 4 times a week swimming or eliptical and/or use weight machines. My plus is always on the low side 40 to 50 bpm andblood pressure is average 120-130 80-88. I take Lipator and do have a  factor V Liden blood condition  but have never had a clot.   My question is: Should I push for surgery to fix the dilation? It has been a year since this scan and the thoracic aorta  is at 4.0 per recent echo.

The size of your ascending aorta is in the aneursym category >0.4 cm), Often an aneursym is closely watched for growth.  For an insight, the aortic diameter gradually increases over time. The normal expansion rate over a period of about 10 years is between 1-2 mm and the expansion may be greater for patients with an aorta that is larger than normal. If the growth factor is is an issue, your doctor may not want to operate.

Has your doctor approved weight training.  It is my understanding that lifting heavy weights is not recommended as the spikes blood pressure, also, systemic blood pressure should be controlled.  My cardiologist wants my blood pressure below 120/80!

Thank you for your comments. I keep the weights low and exercise only for tone not build up.

That is the proper choice. Take care and thanks for sharing.
