A doomed 24-year-old man walked into Downstate Medical Center in Brooklyn with a gunshot wound to the chest and died early Saturday.

The man was one of two shot at about 2:40 a.m. on East 37th Street and Glenwood Road in East Flatbush, cops said.

The second victim, a 29-year-old man, was shot in the leg. He also showed up at the hospital on his own, the NYPD said, and is listed in stable condition.

First responder reports said two suspects left the crime scene in separate vehicles.

There were no arrests.
