Background: Distribution of coronary artery calcium (CAC) has been determined in different heterogeneous populations in the Multi-Ethnic Study of Atherosclerosis (MESA). Based on findings showing that geography and culture can influence CAC scoring beyond traditional race groups, we determined the distribution of CAC in a homogenous black African population to provide an initial basis for a larger CAC score study in Africa.
Methods and results: This is a preliminary study using computed tomography to determine the CAC scores within a black African population who were referred to our center. Other information on patients were recorded through a combination of one-on-one interviews and medical records. A total of 170 patients were involved in our study, including 60.6% males, with an average age of 53.9 ± 9.2 years. The majority (78.8%) had a zero calcium score, with patients within the age group of 55–64 years dominating the non-zero calcium score population. Males were found to have higher calcium levels compared to females, and coronary artery calcification and prevalence steadily rose with the increasing age. However, P-values of 0.328 and <0.001 were observed with distribution of CAC according to gender and age, respectively.
Conclusion: Findings from this study showed that the distribution of CAC was markedly affected by the age of our study population, which will be more apparent in a larger study.
