Epidemiology and Demographics

Incidence

  • The incidence rate of mesenteric ischemia due to superior mesentric artery occlusion is 8.6/100 000/year. 70% of SMA occlusion is caused by embolism and 30% by thrombosis.[1][2][3]
  • The annual incidence of mesenteric ischemia is approximately 5.5% per 100,000 individuals.
  • In United States, between 1995-2010 incidence of mesenteric ischemia declined from 8.4 to 6.7% per 100,000 individuals.
  • Between 1970 and 1982, in the population of Sweden the incidence of mesenteric ischemia was estimated to be 12.9 cases per 100,000 individuals.

Prevalence

  • The prevalence of mesenteric ischemia:[4]
    • Occlusive mesenteric ischemia is approximately per 100,000 individuals worldwide.
    • Non-occlusive mesenteric ischemia is approximately 6000 per 100,000 individuals worldwide.
  • In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.
  • The prevalence of [disease/malignancy] is estimated to be [number] cases annually.

Case-fatality rate/Mortality rate

  • In 2017, the incidence of mesenteric ischemia is approximately 90-200 per 100,000 of surgical admissions with a mortality rate of 50%.[5]

Age

  • The incidence of mesenteric ischemia increases with age; the median age at diagnosis is years.
  • Mesentric ischemia commonly affects individuals older than 60 years of age.
  • [Chronic disease name] is usually first diagnosed among [age group].
  • [Acute disease name] commonly affects [age group].

Race

  • There is no racial predilection to [disease name].
  • [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].

Gender

  • Mesenetric ischemia affects men and women equally.

Region

  • The majority of mesenteric ischemia cases are reported in Sweden.
  • [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
