Ailing BNP chairperson Begum Khaleda Zia will be able to recover completely if she is allowed to go abroad for treatment, her personal physician Professor AZM Zahid Hossain said.
When asked about Khaleda's physical condition at the moment, he declined to go into specifics.
Earlier on the day, a ring was installed in her heart as it suffered a 99% block.
She underwent a coronary angiogram test after suffering a mild cardiac arrest last night.
The Evercare Hospital sources said that Khaleda Zia's physical condition is stable now.
"Khaleda Zia's condition is stable now. She has been admitted to the coronary care unit (CCU) of the hospital," said Dr. Arif Mahmud, head of the medical services of the hospital.
BNP Chairperson's press wing member Shairul Kabir Khan said that a press conference on Khaleda Zia's overall health condition is scheduled to be held this afternoon.
Khaleda Zia was taken to Evercare Hospital in the capital in April for health check-ups.
The 76-year-old former prime minister has been suffering from various ailments, including liver cirrhosis, arthritis, diabetes, kidney, lung, and eye problems.
She was last admitted to Evercare Hospital on 13 November last year where she was diagnosed with liver cirrhosis. On 1 February this year, she returned home after an 81-day stay at the hospital as she was suffering from internal bleeding caused by the liver cirrhosis problem.
Khaleda was sent to the Old Dhaka Central Jail as a lower court sentenced her to five years imprisonment in the Zia Orphanage Trust corruption case on February 8, 2018. Later, she was found guilty in another corruption case the same year.
Amid the coronavirus outbreak, the government temporarily freed Khaleda Zia from jail through an executive order suspending her jail sentence on 25 March 2020, with conditions that she will stay in her Gulshan house and will not leave the country.
