About 2 months ago, I had some minor chest pain, difficulty catching my breath, and extreme sweating, even in air con. I was at Central Festival at the time. I drove across the street to Pattaya Memorial.
They did an EKG, said I was having a small heart attack. They said they were not equipped to handle it and took me in an ambulance to Samitivej in Sri Racha.
Angiogram showed almost zero blood flow in left coronary artery. Doc installed 2 stents. Stayed 2 nights, discharged on my 71st birthday. The nurses gave me a nice party! Now 90% flow.
Total cost: 660,000 THB (out of pocket).
Now on expensive drugs for at least the next year, total about 10,000 THB/month. Statins, aspirin, anti-coagulants, etc.. Brilanta is the worst. ~ 4,500 THB/month. Might switch to Pavlix after one year.
BP was regularly 135-140/80-90. Now 100-110/65-70 every day.
May have been cheaper at Pattaya City (if they could even do it) or Bangkok Pattaya hospital, but I was in no shape to shop around.
One thing I like about living in PTY is the availability of several hospitals. Hope that helps to inform your decision.
Best of luck.
