DUBLIN, Ohio — At age 86, Jack Nicklaus no longer strolls the fairways with a bounce in his step, but age is not the only specific factor in the Golden Bear’s slowdown.
Nicklaus suffers from transthyretin cardiac amyloidosis ATTR-CM, a progressive heart condition most commonly affecting older adults, predominantly men over 60, which can cause an irregular heartbeat and heart muscle problems (cardiomyopathy). The Upper Arlington native first began experiencing health issues related to ATTR-CM in 2015, but it took years to correctly diagnose.
Nicklaus continues to speak out about the disease by relaying the common symptoms of atrial fibrillation (Afib), shortness of breath, heart failure and carpal tunnel syndrome, for which Nicklaus underwent surgery weeks before the 2026 Masters Tournament. He continues to receive treatment for ATTR-CM.
Nicklaus will host the 51st playing of the Memorial Tournament June 4-7 at Muirfield Village Golf Club in Dublin, Ohio, as the PGA Tour event celebrates its 50th anniversary. Nine of the top-10 ranked players in the world are scheduled to compete, including No. 1 Scottie Scheffler, who is the two-time defending champion, and No. 2 Rory McIlroy, seeking his first Memorial win.
