Tarleton State says coach Billy Gillispie won't return after being away from the bench for more than a month because of medical issues. Glenn Cyprien was named acting head coach on Jan. 30, about two weeks after Gillispie stepped away. The 66-year-old Gillispie told The Dallas Morning News earlier this month he was dealing with heart and blood-pressure issues that have plagued him for years. The former Kentucky coach had a kidney transplant in 2018, but told the newspaper his kidney was fine.

Atrial fibrillation, or A-fib, is becoming more common, but doctors say treatments are improving. The condition is a quivering or irregular heartbeat that can lead to blood clots, stroke and heart failure. Experts say more than 10 million Americans have it, mostly older adults. Symptoms include a pounding heartbeat and shortness of breath. Smartwatches and other devices are helping with diagnosis. Causes include genetics, high blood pressure and stress. Treatments range from medications to procedures like ablation. Experts recommend a healthy lifestyle to lower the risk.
