He had a history of heart attack, quadruple bypass, afib, pacemaker, and as of January, CHF. I feel like I must have missed something because he seemed fine the afternoon before. And his bloodwork was fine a few weeks before, his appetite was good, and the swelling in his legs was minimal. I just don't understand. He was 87 but until he went thru sepsis and a broken hip last year was healthy and strong. I really thought he would get better. Was I just in denial?!
