BCCI president and former India captain Sourav Ganguly, who underwent angioplasty after a "mild" heart attack, is stable and his health parameters are normal, doctors said on Sunday.

The cricket icon was diagnosed with three blocked coronary arteries on Saturday, following which a stent was inserted in one to remove the blockage.

"He had an uneventful last night and presently Afebrile (not feverish)... He is sleeping now," a bulletin issued by the private hospital where Ganguly is admitted, said.

His blood pressure is 110/70 and oxygen saturation level is 98 per cent, it said.

Doctors said they will be deciding on conducting another angioplasty after assessing Ganguly’s condition.

To a question, a hospital spokesperson said the medical board is not thinking about the option of bypass surgery. "Our expert panel will decide about the future course of treatment tomorrow," he said.

"He has taken breakfast, read newspapers and chatted with the hospital staff in the morning. A routine ECG was also conducted... His oxygen support has been removed," one of the doctors treating Ganguly told reporters.

Fans of the celebrated former cricketer were seen holding posters that read “Come back dada” outside the hospital, which saw a beeline of visitors like Saturday.

Ganguly complained of chest pain following a workout session on Friday evening and family members took him to the hospital Saturday afternoon when the problem recurred.

Bengal Chief Minister Mamata Banerjee expressed concern over Ganguly's hospitalisation.

"Sad to hear that Sourav Ganguly suffered a mild cardiac arrest and has been admitted to hospital. Wishing him a speedy and full recovery. My thoughts and prayers are with him and his family," Banerjee tweeted.

The development came at a time when speculations were rife about his joining politics ahead of the state assembly elections likely in April-May this year.

According to political circles in the state, the former batting great could join the BJP, but Ganguly himself never made his intentions quite clear about taking the political plunge.
