Researchers found that at around 6:30 a.m. the circadian system sends out an increased amount of PAI-1 cells which blocks blood clots from breaking down. The more PAI-1 cells in the blood, the higher the risk for a blood clot that leads to a heart attack

I've been diagnosed with coronary heart disease and my doctor recommended bypass surgery but I've also heard about EECP and chelation therapy as alternatives. I'm really confused about which option to choose and worried about the costs. One source said EECP costs around 70-80 thousand but a local hospital quoted 2.5 lakh rupees. Can you help me understand the pros and cons of each treatment and why there's such a big difference in the cost?

Bypass surgery is a major decision. EECP is non-invasive and more affordable, but bypass surgery may offer more immediate results. The cost difference is often due to location, equipment, and the type of care provided at the hospital.
