Patients with type 1 diabetes have higher rates of sudden cardiac death (SCD), with a nearly 10-fold increased risk at ≤ 30 years and a 20-fold increased risk in ages 30–40 years, according to a Danish study. Type 2 diabetes patients also showed increased SCD risk, with a nearly sixfold increase up to 30 years and a 5.6-fold increase in ages 30–40 years. The study highlights the need for better diabetes treatment and prevention strategies.
