Prevalence of coronary heart disease in Kin-Chen, Kinmen.
We estimated the prevalence of coronary heart disease (CHD) by the Minnesota code of a 12-lead resting electrocardiogram, Rose chest pain questionnaire and self-reported previous medical history in Kin-Chen, Kinmen (Quemoy), an island under military control for 40 years and the focal point of confrontation between mainland China and Taiwan. Among the target population of 6346 who accounted for all residents aged over 30, 3826 (60.3%) responded with complete data. The prevalence of probable CHD (Minnesota code 1.1-1.2) was 4.1% (71/1732) in men and 4.0% (84/2094) in women, whereas the prevalence of possible CHD (Minnesota code 1.3, 4.1-4.4, 5.1-5.3 and 7.1.1) was significantly higher in women (21.4%) than in men (11.6%). When compared to Chinese populations elsewhere, the increased overall prevalence may suggest a link to long-term stress conditions under military control. We also found the abnormal ECG was associated with many risk factors of CHD, particularly win women. The prevalence of Rose angina and self-reported angina or myocardial infarction was, however, low and associated poorly with any cardiovascular risk factors. Long-term follow-up studies are needed to determine the predictive value of these electrocardiographic abnormalities for cardiovascular disease morbidity and mortality in this population.
