(AP) — Country music singer Randy Travis is in critical condition at a Texas hospital after being hospitalized for heart problems.

A news release from the singer’s publicist says the 54-year-old Travis was admitted to the hospital Sunday in Dallas and was in critical condition Monday evening.

Publicist Kirt Webster said Travis is suffering from viral cardiomyopathy, a heart condition caused by a virus. The Mayo Clinic website says the disease weakens and enlarges the heart muscle, making it harder for the heart to pump blood and carry it to the rest of the body. It can lead to heart failure.

Long a popular figure in country music, the North Carolina-born singer had been putting his life back together after a series of embarrassing public incidents involving alcohol.
