The family of Jean-Marc Vallée says the late writer and director died from an irregular heartbeat and coronary artery disease, Deadline reports.

The final coroner’s report states Vallée suffered from “a fatal cardiac arrhythmia secondary to severe coronary atherosclerosis” when he died at his family’s lakeside cabin in Quebec on Christmas Day at age 58,the family saidin a statement to the outlet on Wednesday.

Vallée was originallybelieved to have diedfrom a heart attack.

Vallée’s sons Alex and Émile Vallée said their father continues to be remembered worldwide through “testimonials of friendship, esteem and respect.”

“We are sincerely grateful and we hope that his creativity will continue to serve as inspiration and guidance to the people in this industry that he was so passionate about,” the sons added, per Deadline.

Vallée was best known for directing several highly-acclaimed projects includingBig Little Lies,Dallas Buyers Club, andWild and Sharp Objects. His breakout feature film wasC.R.A.Z.Y., which he wrote and directed.

According to Deadline’s initial report revealing Vallée’s death, the director did not drink alcohol and was known as a fitness fanatic, even taking on the Wim Hof method — a fitness practice that involves exposing the body to ice-cold temperatures and achieving heightened oxygen levels through breathing techniques.

Vallée is believed to have died on Christmas Day and was found the next morning, per the outlet’s previous report.

Coronary artery disease — also known as ischemic heart disease — kills 70,000 Canadians each year,per the University of Ottawa. It is the second-leading cause of death in the country behind cancer.

Though health concerns such as being overweight, physical inactivity, unhealthy eating, and smoking tobacco are among the main risk factors for coronary artery disease, “a family history of heart disease also increases your risk for CAD, especially a family history of having heart disease at an early age (50 or younger),” the CDC says.

According to the University of Ottawa, four in 10 Canadians have at least three risk factors for coronary artery disease, with nine in 10 people over the age of 20 having at least one.
