Answers are grounded in this paper and cite their sources.
We found that from 1976 through 1983 the incidence of acute myocardial infarction (AMI) diagnosed among Navajo Indians remained low (0.5 per 1,000 persons age 30 years or more), although the incidence in women appears to be climbing. Navajo AMI patients are more likely to be hypertensive and diabetic than age- and sex-matched patients with gallbladder disease. Twenty-four per cent die within one month of AMI.

Coulehan et al. (1986) conducted an observational in Acute myocardial infarction. Navajo Indian population / Acute myocardial infarction vs. Age- and sex-matched patients with gallbladder disease was evaluated on Incidence of acute myocardial infarction and 1-month mortality. Navajo Indians aged ≥30 years had a low incidence of acute myocardial infarction from 1976 to 1983 (0.5 per 1,000 persons), with a 24% one-month mortality rate.
