Regular exercise is generally considered to reduce the risk of coronary heart disease. Reduced levels of physical activity in Indo-Asians may partly explain why patients from this ethnic group sustain so many heart attacks.
To investigate ethnic differences in pre-admission levels of physical activity amongst patients admitted with myocardial infarction and triggers for the acute cardiac event.
Cross-sectional study using standard Baecke questionnaire, which provided a semi-quantitative work score, sport score, leisure score and total activity score of general daily activities, with additional questions on activity at the onset of chest pain.
Coronary Care Unit, City Centre Teaching Hospital.
We studied 100 consecutive patients (76 males, mean age 62.3 years, S.D. 12.5; 74 caucasians, 26 Indo-Asians) admitted with myocardial infarction. Most patients were engaged in sedentary activities, including lying in bed (25%), sitting (19%), watching television (14%) and sleeping (6%), whilst only 21% of patients were engaged in physical activity at chest pain onset; there were, however, no ethnic differences in activity at chest pain onset. There was a diurnal variation in chest pain onset, with the mode between 08:00 and 10:00 h. As the mean age of Indo-Asians was significantly lower than caucasians in the whole group (56.3 vs. 64.4 years; t-test, P < 0.002), the Baecke questionnaire analysis was confined to only male patients aged < 70 years (n = 56). Indo-Asian patients with myocardial infarction were found to have a significantly lower overall physical activity score (3.78 vs. 5.33; P = 0.003), leisure time physical activity (2.43 vs. 2.74; P < 0.05) and sporting score (0.14 vs. 0.82; P < 0.01) when compared to caucasians, despite a similar mean age and body mass index.
The majority of myocardial infarction patients were engaged in sedentary activities at chest pain onset. Although there were no differences between caucasians and Indo-Asians in activity at symptom onset, Indo-Asian patients had a significantly lower overall physical activity score, leisure time physical activity and sporting score compared to caucasians. The lower general physical activity amongst Indo-Asians may in part contribute to the high prevalence of ischaemic heart disease amongst this ethnic group.
定期锻炼通常被认为可降低冠心病风险。印度裔亚洲人身体活动水平较低可能部分解释了为何该族群的患者心脏病发作如此频繁。
调查心肌梗死患者入院前身体活动水平的种族差异以及急性心脏事件的诱因。
采用标准的贝克问卷进行横断面研究，该问卷提供了一般日常活动的半定量工作得分、运动得分、休闲得分和总活动得分，并附加了关于胸痛发作时活动情况的问题。
市中心教学医院冠心病监护病房。
我们研究了100例连续入院的心肌梗死患者（76名男性，平均年龄62.3岁，标准差12.5；74名白种人，26名印度裔亚洲人）。大多数患者从事久坐活动，包括卧床（25%）、坐着（19%）、看电视（14%）和睡觉（6%），而只有21%的患者在胸痛发作时进行身体活动；然而，胸痛发作时的活动情况在种族间并无差异。胸痛发作存在昼夜变化，发作高峰在08:00至10:00之间。由于整个组中印度裔亚洲人的平均年龄显著低于白种人（56.3岁对64.4岁；t检验，P<0.002），贝克问卷分析仅限于年龄<70岁的男性患者（n = 56）。与白种人相比，心肌梗死的印度裔亚洲患者总体身体活动得分（3.78对5.33；P = 0.003）、休闲时间身体活动得分（2.43对2.74；P<0.05）和运动得分（0.14对0.82；P<0.01）显著更低，尽管平均年龄和体重指数相似。
大多数心肌梗死患者在胸痛发作时从事久坐活动。尽管白种人和印度裔亚洲人在症状发作时的活动情况无差异，但与白种人相比，印度裔亚洲患者的总体身体活动得分、休闲时间身体活动得分和运动得分显著更低。印度裔亚洲人较低的总体身体活动水平可能部分导致了该族群缺血性心脏病的高患病率。
