Figures

• 

  Fig 1. Prevalence of HF in (A) total population and (B) men and women between 2004 and 2014. The crude prevalence of HF was 1.42% in 2004 and steadily increased to 1.98% in 2014. However, the age-adjusted prevalence of HF tended to be stable at 1.42% in 2004, increasing to 1.43% in 2014. The prevalence rates of HF in men and women was 1.1% and 1.7%, respectively, in 2004, while that in women was consistently higher than that in men over the 11-year study period (1.8% and 2.1%, respectively, in 2014).

  Fig 2. Prevalence of HF according to the age group between 2004 and 2014. The prevalence of HF was steeply increased especially in older adults (over 85 years old).

• 

  Fig 3. Incidence of HF in (A) total population and (B) men and women between 2004 and 2014. The crude incidence of HF was stable between 2004 and 2014. The age-adjusted incidence of HF decreased from 6.07 per 1000 person-years in 2004 to 3.94 per 1000 person-years in 2014.

  Fig 5. Hospitalized HF (per 1000 person-years) between 2004 and 2014. The number of hospitalized patients with HF increased from 1.40 per 1000 person-years in 2004 to 1.87 per 1000 person-years in 2014.
