The late rapper's autopsy revealed that Heavy D died from a pulmonary embolism. A long flight from Europe may have contributed to his death as well.
The embolism resulted from a blood clot traveling from a leg vein into an artery in his lungs. Blood clots can build from long stationary periods and Heavy's flight from Wales could have caused the clot to form.
L.A.'s Coronor's Office also revealed Heavy had heart disease which also could have contributed to his death.
Heavy was only 44 years old when he passed away November 9th.
