Among the millions living with diabetes, a quiet crisis has long gone unnoticed — hearts straining in silence while fatigue and breathlessness are chalked up to the condition itself. A landmark trial from the University of Glasgow has revealed that nearly one in four diabetic patients carries undiagnosed heart failure, detectable through a simple blood test already available in most clinics. The TARTAN-HF trial, presented at the American College of Cardiology Conference, found that early detection and treatment reduced the risk of hospitalization or death by 55 percent — a finding that asks me
