Hi there. You may be a candidate for stenting? With the info supplied its hard to be sure, but the best advice would be to ask your Cardiologist, as he would have all your results in detail & any medical history. Best of luck
My cardiologist said as the position s at the distal part, stent cannot be proceeded as it is less than 2mm diameter. And the risk is relatively low as the functions can be performed by others. He just reminded me to take the liptor to maintain a healthy level.
A CT is not the best tool for the analysis of severity of blockages. The best tool is still an angiographic procedure with FFR measurements.
Lets however assume that the outcome is correct.
For the 30% stenosis treatment is not necessary. The 70% stenosis can give you problems.
As it is however not stentable (being <2mm) you need medication only.
If the stenosis progresses slowly, despite the medication, you will probably form other vessels that take over the function of the (more and more) blocking vessel.
In the worst case, if the vessel suddenly blocks completely, you might suffer a minor heart attack (minor because only a small part of the heart is provided with blood from this vessel)
Given Lcx and the CT noted blockage, I think I would want that checked via cath and done with FFR to note the severity of the blockage. Small vessels can be stented. My circumflex had a FFR significant 90% blockage opened with a Boston Scientific 2.5mm x 12 mm Promus Premier DES. I know each person is different but I think mentioning it might be helpful. YMMV. I know I felt miserable with my ccx blocked as it was. Once opened, it made a significant difference. The balloon comes in as pre-treatment to open the vessel which may allow a stent to be placed. Personally I'd want that artery to be reviewed in the cath lab with FFR (Fractional Flow Reserve). If they can't stent, it's possible a balloon may help for a period of time.
I'm on Crestor, which has some rough side effects but does do a better job at cholesterol management and even can cause some regression of plaques. Maybe you could ask your doc about Crestor. Good luck!
