The legendary yoga guru was admitted to a hospital in Pune on August 12 following complaints of acute breathlessness and palpitation, Dr Deepali Mande, who attended on him said. "He did not want to be admitted to hospital even though he was unwell at home for almost three weeks. Iyengar had a cardiac (ailment) history. His condition subsequently worsened leading to renal failure after which he was put on dialysis," she said.
