心胸比率是根据生活在牙买加农村和郊区社区的929个典型样本的全尺寸胸片估计的，这些样本主要是非洲血统的男性和女性，年龄35-。女性的CTR大于男性，并随着年龄的增长而增加；它们与体重和血压水平相关。牙买加的平均CTR大大高于生活在威尔士的白人的可比样本。这些差异不能用包括高血压在内的心血管疾病的患病率或体重或体力活动的差异来解释。可能在心脏在胸腔内的位置或胸径的大小上存在种族差异。在根据胸片评估心脏大小时，应考虑黑人较大的CTR。
Cardiothoracic ratios were estimated from 929 full-sized chest radiographs of representative samples of men and women of predominantly African origin aged 35–64 years living in rural and suburban communities in Jamaica. CTRs were greater in women than in men and increased with age; they were correlated with weight and with blood pressure levels. Mean CTRs were substantially greater in Jamaica than in a comparable sample of white persons living in Wales. These differences could not be explained by the prevalence of cardiovascular disorders including hypertension or by differences in weight or physical activity. An ethnic difference, possibly in the position of the heart within the chest or in the size of the thoracic diameter, is suggested. The greater CTR of the Negro should be taken into account when assessing heart size from chest films.
