Pope Francis died of stroke and heart failure

Pope Francis died after a stroke and irreversible heart failure, Vatican doctor Andrea Arcangeli said in a death certificate released on Monday evening.
The certificate, which was published by the Vatican, said the pontiff, 88, had fallen into a coma before his death early on Monday.

Pope Francis had been considerably weakened after a severe respiratory infection kept him in hospital for five weeks. Doctors said he developed pneumonia in both lungs and suffered two episodes of "acute respiratory failure" before he was discharged on March 23.

The Pope had suffered increasingly poor health in recent years, with bouts of bronchitis and knee pain that forced him to use a wheelchair.
