Coronary Artery Checkup

In early 80s I had a sroke, and as a treatment got a procedure/operation of "baloon arteries enlargement". To make a long strory short, for several years I didn't have any heart attacks or other problems, and didn't use any medications. But recently I start feeling problems with my legs - walk difficulties, etc. My feet are often swollen, the same as if the blood isn't coming through.

I know that I can't delay a visit to the doctor and checkup any longer.

So, now I'm searching for a doctor/hospital for my heart checkup, and so far, have heard of Prof Keitchai Pooripaniya at Piyavate Hospital.

Any recommendations on the specialists and tests available today in Thailand...
