KOLKATA: A series of medical tests would be conducted on BCCI president Sourav Ganguly on Thursday following which a decision might well be taken on the next course of treatment, a senior doctor at the hospital where he has been admitted said. The former Team India captain, hospitalised on Wednesday for the second time in a month, was likely to undergo angiography, and doctors would subsequently decide if another stent insertion was necessary. Earlier in January, he was diagnosed with 'triple vessel disease' and had a stent inserted in a coronary artery after suffering a mild heart attack. "Mr Ganguly slept well all night. He had a light breakfast this morning. A series of tests will be conducted on him today to decide on the next course of treatment," the senior doctor, who is part of the panel attending to the cricketing icon, said.
