Epidemiology and Demographics

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.

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.

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

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].

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].

[Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
