Kolkata, Sep 18 (IANS): BCCI president Jagmohan Dalmiya, who was admitted to hospital on Thursday night after he complained of chest pain, underwent angiography, hospital sources said.

The 75-year-old has been admitted to the city's B.M. Birla Hospital.

"He complained of severe chest pain and now has been put in the Intensive Care Unit, doctors are constantly monitoring his condition. He was brought in around 9 pm today (Thursday)," a hospital spokesperson had told IANS.

In a medical bulletin it was later revealed that Dalmiya underwent "coronary angiography".

"Multiple lesions were observed with total occlusion of the left anterior descending coronary artery," it was said in the bulletin.

Doctors said he is "being closely monitored in the coronary critical care unit".

It also mentioned that he was brought to the hospital almost six hours after the onset of chest pain.

The veteran cricket administrator has not been keeping well for a while and was not actively taking part in the day-to-day functioning of the Board of Control for Cricket in India.

When he was being hospitalised, son Abhishek Dalmiya was reportedly by his side. Later Cricket Association of Bengal (CAB) officials including former India captain and CAB joint secretary Sourav Ganguly and treasurer Biswaroop Dey rushed to the private hospital.

Sports and Youth affairs minister Arup Biswas, too, visited the hospital.

Dalmiya took over the reins of BCCI in March, after a gap of 10 years, when he won the elections unopposed.

But he has been suffering since then, and his health has deteriorated further over the last few weeks.
