Longer the duration of diabetes, greater the risk for developing heart failure, stated an analysis of around 10,000 U.S. adults followed for about 23 years.

A multivariable analysis revealed that there was a steady and significant escalation in the rate of incident heart failure with increase in diabetes duration. Among 168 study subjects, constituting 2% of the total study group, who had diabetes for at least 15 years, the incidence of heart failure was shown to be around three times higher than among 4,802 individuals (49%) who never had diabetes or prediabetes, reported researchers in JACC Heart Failure.

Individuals with prediabetes, who constituted 32% of the study population, demonstrated a significant yet modest increase in the rate of incident heart failure - 16% higher than control group that never developed diabetes. People with diabetes for duration of 0-4.9 years, 5.0-9.9 years, or 10-14.9 years, demonstrated a steady rise in relative incident heart failure rates of 29%, 97%, and 210%, respectively, compared to controls… (Medscape)
