A livery cab driver was killed when he had a heart attack and crashed into a double-parked truck Friday in Brooklyn, cops said.

Elin Medar, 37, was driving down East 100th Street near Foster Avenue in Canarsie at about 1:40 p.m. when he suffered the attack, lost control of the cab, and slammed into the unoccupied delivery truck, cops said.

Medar was rushed to Brookdale Hospital where he was pronounced dead on arrival.

No criminality is suspected and the investigation is ongoing, cops said.
