This article aims to study the prevalence of coronary artery calcification and associated factors in a multiethnic population in Angola.
A descriptive, cross-sectional observational study was carried out in a private clinic in Angola. For this purpose, information was collected from sociodemographic and biological data. The selected variables were; history of arterial hypertension, diabetes mellitus, smoking (current and past), alcohol consumption, family history of coronary disease, and coronary calcium score. Independent Mann-Whitney test, Student's -test and chi-square test were used as appropriate.
The sample consisted of 211 individuals: 156(73.9%) of black race, 37(17.4%) of mixed race and 18(8.4%) of Caucasian race. 126(59.7%) were male. The average age was 56.7 ± 9.3 years. Of the total sample, 158 (74.9%) had a history of hypertension, 50 (23.7%) of diabetes mellitus, and 138 (65.4%) of dyslipidemia. Of the total number of individuals, 21(10.0%) were smokers and 38(18.0%) were ex-smokers, 137 (64.9%) were social drinkers and 44(20.9%) were obese. A significant association was found between calcification of the coronary arteries and aging (p <.001), Caucasian race (p =.037), and a history of diabetes mellitus, dyslipidemia and smoking (p <.001, p <.001, p =.012, respectively). Black race and female gender are associated with a lower risk of coronary artery calcification (p =.034 and p =.011, respectively).
The present results support the notion that there are racial and ethnic differences in the prevalence of coronary calcification.
本文旨在研究安哥拉多民族人群中冠状动脉钙化的患病率及相关因素。
在安哥拉的一家私人诊所开展了一项描述性横断面观察性研究。为此，收集了社会人口统计学和生物学数据信息。所选变量包括：动脉高血压病史、糖尿病史、吸烟（当前和既往）、饮酒情况、冠心病家族史以及冠状动脉钙化评分。根据情况适当使用独立曼-惠特尼检验、学生 t 检验和卡方检验。
样本包括211名个体：黑人156名（73.9%）、混血人种37名（17.4%）、白种人18名（8.4%）。男性126名（59.7%）。平均年龄为56.7±9.3岁。在总样本中，158名（74.9%）有高血压病史，50名（23.7%）有糖尿病史，138名（65.4%）有血脂异常。在个体总数中，21名（10.0%）为吸烟者，38名（18.0%）为既往吸烟者，137名（64.9%）为社交饮酒者，44名（20.9%）为肥胖者。发现冠状动脉钙化与衰老（p<.001）、白种人（p =.037）以及糖尿病、血脂异常和吸烟史（分别为p<.001、p<.001、p =.012）之间存在显著关联。黑人种族和女性与冠状动脉钙化风险较低相关（分别为p =.034和p =.011）。
目前的结果支持冠状动脉钙化患病率存在种族和民族差异这一观点。
