“He is doing well,” said Prof Dr Abu Nasar Rizvi of Bangabandhu Sheikh Mujib Medical University (BSMMU).
“Doctors are preparing to conduct a bypass surgery next week,” Rizvi said.
His condition has been improving gradually over the last few days and the minister was able to walk on Monday.
Quader was admitted to BSMMU on March 3 following breathing complications but tests revealed three blockages in his coronary artery.
He was flown to Singapore the next day for treatment at the Mount Elizabeth Hospital.
Cardiothoracic surgeon Dr Sivathasan Cumaraswamy, a member of the medical board treating Quader, also briefed his family members about his improvement.
