      In a recent systematic review it was estimated that the global prevalence of peripheral artery disease (PAD) was 5.6%, with higher prevalence estimates in high-income countries than in low-income countries.

      • Temporal Trends in Hospitalization for Lower Extremity Peripheral Artery Disease in Ontario: The Importance of Diabetes
        Canadian Journal of CardiologyVol. 37Issue 10
        • Preview
          We sought to assess temporal trends in peripheral artery disease (PAD)-related hospitalization rates in Ontario. Trends in quarterly rates of PAD hospitalization per 100,000 Ontarians between 2006 and 2019 were assessed using autocorrelated linear regression. Stratified analyses according to age, sex, and most responsible diagnosis code type (with vs without diabetes-specific PAD codes) were performed. From 2006 to 2019, overall PAD hospitalizations did not decrease significantly when diabetes-specific codes were included.
