Would urge you to be a little cautious. If the person doesn't have any symptoms of MI, then it may be better to go to a reputable diagnostic clinic nearby for ECG, Stress Test and Echocardiogram.
Thee problem with going to cardiac surgeons or interventional cardiologists is that once you go to them, it may result in a procedure. These days angioplasty (stenting) has become routine and there are many articles about their excessive usage on the web. An expose a few years ago by New York Times mentioned one person in the US who had 17 stents put all over his body.
Stenting costs range from as low as Rs. 60,000 to as high as Rs. 2.5 lakh per stent. There is a conflict of interest as medical professionals do not mention the alternative, bypass surgery, which is sometimes more appropriate than multiple stents on the same artery and costs less at approx. Rs. 1.5 to Rs. 2 lakh.
