Objective: To compare the distribution of risk factors and clinical outcome of acute coronary syndrome (ACS) between Kuwaiti and other Arab men living in Kuwait.
Subjects and methods: The data for this study was collected from the computerized database at the Mubarak Al-Kabeer Hospital, Kuwait and the 1997-2000 census data for the State of Kuwait. 1,329 Arab men (666 Kuwaitis and 663 other Arabs) older than 25 years who were admitted between September 1997 and August 2000 with a diagnosis of ACS were included in the study.
Results: The rate of admission for the entire patient population was twofold higher for Kuwaiti (1.68/1,000) than other Arab men (0.72/1,000), (p < 0.001); the mean age of the Kuwaiti men was 56.7 +/- 11.9 years and other Arab men 53.0 +/- 10.5 years (p < 0.001). The prevalence of hypertension, diabetes, smoking and hypercholesterolemia for Kuwaiti men was 35.9, 56.9, 51.7 and 36.2%, respectively; the corresponding prevalence for other Arab men was 28.8, 42.7, 68.2 and 32.0%, the difference in the prevalence except for hypercholesterolemia was significant (p < 0.001). In Kuwaiti men younger than 55 years of age, the prevalence of hypertension, diabetes mellitus, smoking and hypercholesterolemia was 26.6, 49.5, 68.6 and 43.3%, respectively; the corresponding values for other Arab men was 22.3, 36.2, 77.7 and 43.3%; the difference in prevalence except for hypertension was significant (p < 0.001). The in-hospital mortality for the whole study was 6.2% (Kuwaiti) and 2.3% (other Arab men; p < 0.001); while that for men younger than 55 years was 2.7% (Kuwaiti) and 0.8% (other Arab men; p < 0.05).
Conclusion: The rate of admission for the entire patient population with a diagnosis of ACS was twofold higher for Kuwaiti than other Arab men. Among all patients and also those less than 55 years, the prevalence of diabetes mellitus was consistently higher among Kuwaiti than other Arab men thereby probably leading to the higher admission rate and in-hospital mortality.
