Ho was diagnosed with cardiomyopathy in 2005. He had a pacemaker implanted. He talked with a biotechnology company that dealt with treating heart conditions with adult stem cells. This company was working with Dr. Shoa, cardiac surgeon and one of the first people to work with adult stem cells for heart disease. On December 6, 2005, Ho had his own stem cells put into his heart by Amit Patel and his other doctors in Thailand. The treatment went without problems. Later in the month, Ho said, "I'm feeling much better and I'm so happy I came up here to do it."
