Preval died of heart disease:

The eagerly anticipated results of an autopsy of former Haitian President Rene Preval showed the leader died in March after a heart irregularity cut off his ability to breathe, officials said on Wednesday.

The 74-year-old Preval, who was the first president in Haitian history to win a democratic election, serve a full term and peacefully hand power to a successor, died unexpectedly on March 3 after falling unconscious at his home.

“Effectively, there had been a certain suspicion because the death was sudden,” Clame-Ocnam Dameus, Haiti’s prosecutor, told journalists.

He said Preval’s heart had swollen and turned black, harming his ability to breathe. Dameus emphasized that chronic disease caused Preval’s death, not foul play. (RTRS)
