Known cardiovascular risk factors account for approximately 90% of myocardial infarctions in African populations, consistent with global data.
Known CVD risk factors account for approximately 90% of MI observed in African populations, which is consistent with the overall INTERHEART study. Contrasting gradients found in socioeconomic class, risk factor patterns, and AMI risk in the ethnic groups suggest that they are at different stages of the epidemiological transition.
Steyn et al. (2005) studied this question.
