Earlier, Ganguly was working out at the gym in his home when he felt unwell and dizzy
Sourav Ganguly (48), former captain of India's cricket team and president of the Board of Control for Cricket in India (BCCI) is currently stable.
He had a light dinner a few hours after undergoing coronary angiography at 3pm on Saturday at a private hospital in Kolkata, reports Hindustan Times.
Earlier, he was detected with three blocked arteries.
The authorities at Woodlands Hospital said around midnight on Saturday that percutaneous transluminal coronary angioplasty (PTCS) and stenting in his right coronary artery was done through the radial route.
Revasculation to the left anterior descending artery and the obtuse marginal artery will be done later.
Later on Monday, doctors will decide how to treat these conditions.
The Ganguly's family has a history of heart disease, according to the authorities.
Ganguly was working out at the gym in his home when he felt unwell and dizzy around 11am.
Dr Rupali Basu, MD and CEO, Woodlands, said in a statement on Saturday midnight that Ganguly arrived at the emergency department around 1 pm. He had discomfort in the chest and had vomited while working out.
The ECG report showed acute inferolateral wall myocardial infarction and echocardiography pointed at mild inferior wall hypokinesia. Ganguly tested negative for Covid-19.
West Bengal chief minister Mamata Banerjee, Bengal governor Jagdeep Dhankhar, a number of cabinet ministers rushed to the hospital to visit Ganguly in the evening.
Bharatiya Janata Party leaders also inquired about Ganguly's health. BJP national general secretary Kailash Vijayvargiya said Union home minister Amit Shah told state BJP leaders that the Centre would make available all facilities required for Ganguly's treatment.
"I cannot believe that a sportsperson so fit could have a heart attack. He smiled at me and asked about my health instead. I came to know that he never underwent any precautionary test. This must be made mandatory for all cricketers," said Mamata Banerjee after visiting Ganguly.
Ganguly has been the BCCI president since October 2019. His elder brother Snehasish was also a first-class cricketer and is now an administrator at the Cricket Association of Bengal.
