A preexisting condition might have had a part to play in a car accident that killed a Queens man and injured 6 others on Sunday, police said.
Anthony Boyd, 45, died soon after what investigators believe was some sort of medical emergency as he drove his family through Astoria at around 4:40 p.m.
Boyd was driving the Kia Sedona down 35th Avenue with his wife, daughter and two grandchildren when he is thought to have lost control of the van as it approached 21st Street.
The vehicle struck the curb and crashed into a fire hydrant before the minivan flipped its passengers on its side.

Cops arrived at the scene at around 4:46 p.m. to find the flipped van and an injured 72-year-old pedestrian who was hit by flying debris after the accident.
Paramedics rushed Boyd to Mount Sinai Queens Hospital, where he was pronounced dead on arrival.
His family was taken to Elmhurst Hospital Center, where officials said they were in sable condition. The elderly passerby was also in stable condition after treatment at Mount Sinai Queens.
