Ethnic variations in prevalence, presentation characteristics, and mortality have been identified in Canadian patients with coronary artery disease. Similar data with respect to heart failure do not exist. A retrospective sequential chart review of South Asians and non-South Asian Whites in Canada hospitalized with a primary diagnosis of congestive heart failure between 1997 and 1999 showed South Asians were significantly younger, of lower body mass index, were more often diabetic, and were less often smokers. In-hospital mortality was not different between groups, although South Asians were more likely to experience ventricular arrhythmias. Despite presenting at a younger age, South Asians had more high-risk features at hospital discharge. Since South Asians are at high risk of developing premature coronary artery disease, a more aggressive approach to prevention strategies in this ethnic group may reduce the subsequent burden of heart failure.
加拿大冠心病患者在患病率、临床表现特征和死亡率方面存在种族差异。关于心力衰竭的类似数据并不存在。对1997年至1999年间因充血性心力衰竭首次住院的加拿大南亚人和非南亚白人进行回顾性连续病历审查发现，南亚人明显更年轻，体重指数更低，糖尿病患者更多，吸烟者更少。两组间住院死亡率并无差异，尽管南亚人更易发生室性心律失常。尽管南亚人发病年龄较轻，但出院时具有更多高危特征。由于南亚人患早发性冠状动脉疾病的风险较高，对该种族群体采取更积极的预防策略可能会减轻随后的心力衰竭负担。
