Abstract. Aim: The aim of this retrospective cohort study is to assess the effect of
hypertension among the Qatari and non-Qatari patients admitted to hospital in Qatar with
acute myocardial infarction (AMI). Methods: A total of 22,440 Qatari and non-Qatari
patients (40% males and 60% females) were admitted with AMI with or without hypertension
in the Hamad General Hospital, State of Qatar from 1991 to 2002. The diagnostic
classification of definite AMI was made in accordance with criteria based on the
International Classification of Disease tenth revision (ICD-10). Data analysis was performed
using stepwise logistic regression analysis. Results: Of all patients, 8976 (40%) were Qataris
and 13,464 (60%) were non-Qataris. 5390 (24%) patients admitted with AMI. Qataris with
AMI were 1598 and 601 among them were hypertensive and non-Qataris with AMI were 3792
and 826 among them were hypertensive. Also, the incidence of hypertension was slightly
higher in females than in males both among the Qataris 41.1% vs 20.5% (P < 0.001) and
among the non-Qataris 13.0% vs 3.2%. Hypertension cases were rising sharply with
increasing age (P < 0.001) among the Qataris. The results of stepwise logistics regression
analysis showed that there was a statistically significant association between AMI and
gender, diabetes, hypercholesterolemia, shortness of breath, and smoking. Conclusion: The
present study revealed that there is a strong association between AMI, hypertension, DM,
and other CVD risk factors, indicating the importance of the need for more effective
prevention programs and control of hypertension and AMI.
