Alfredsson et al., (1982)

Case-control study in Stockholm County, Sweden

Incident myocardial infarction

356 cases and matched controls

The overall RR for Finnish immigrants compared to native Swedes was 1.7.  For the group of Finnish immigrants who had been in Sweden for 20 years or more the RR was 1.3.

Hedlund et al., (2007)

Case-control study in Stockholm County, Sweden

Incident myocardial infarction

46,366 cases of incident myocardial infarction and stratified controls

Foreign-born subjects had a higher incidence of myocardial infarction than those born in Sweden (RR for men = 1.17, 95% CI 1.13, 1.21; RR for women = 1.15, 95% CI 1.09, 1.21).  An increased incidence was present primarily in subjects born in Finland, other Nordic countries, Poland, Turkey, Syria and South Asia in both genders, from the Netherlands among men, and from Iraq among women.

Hedlund et al., (2008)

Population-based cohort study in Stockholm, Sweden

 Total mortality

Incident cases of myocardial infarction

After adjustment for socioeconomic status, male immigrants had a lower mortality within 28 days after a first myocardial infarction compared to Sweden-born (OR = 0.84, 95% CI 0.76, 0.94).  Among women, there was a weak similar relationship (OR = 0.92, 95% CI 0.76, 1.10).  There were no important differences between foreign-born and Sweden-born in 1-year mortality.

Saposnik et al.,(2010)

Population-bases, matched, retrospective cohort study in Ontario, Canada

Hospitalization for acute myocardial infarction

Persons at risk for myocardial infarction

The incidence rate of acute myocardial infarction was 4.14 per 10,000 persons among new immigrants and 6.61 per 10,000 person-years among long-term residents (HR = 0.66, 95% CI 0.63, 0.69).

Hempler et al., (2011)

Registry-based follow-up study in Denmark

Incident acute myocardial infarction

Persons at risk of acute myocardial infarction

Immigrant men and women from Turkey and Pakistan had an increased incidence of acute myocardial infarction.  No notable differences were observed between former Yugoslavians and native Danes.

Deckert et al., (2013)

Retrospective cohort study in Germany

Total mortality and acute myocardial infarction incidence

Persons at risk for acute myocardial infarction

Acute myocardial infarction incidence was higher in male repatriates (standardized incidence ratio = 1.30, 95% CI 1.02, 1.65) than in the general German population.

van Oeffelen et al., (2014)

Population-based cohort study in The Netherlands

Acute myocardial infarction and total mortality

Persons hospitalized for acute myocardial infarction

Mortality and acute myocardial infarction readmission rates were higher among immigrants as compared with ethnic Dutch.

Dzayee et al.., (2014)

Nationwide cohort study in Sweden

Recurrent myocardial infarction

518,503 patients diagnosed with first myocardial infarction

Foreign-born men and women had a slightly increased HR than Sweden-born men and women.  Foreign-born who had lived in Sweden for less than 35 years had a higher risk than those who had lived there for 35 years or longer.

Shvartsur et al., (2018)

Retrspective cohort study in Israel

Total mortality

11,143 Israeli-born and immigrant acute myocardial infarction patients

10-year mortality rates were 65% lower in Israeli-born patients compared with immigrants.
