We examined the effect of silent myocardial ischemia (SMI) on functional fitness levels and physical independence in 60-79-year-old individuals.
We conducted a cross-sectional study with 716 older adults and used an electrocardiograph and an ambulatory electrocardiogram to diagnose those with SMI. Physical independence was assessed using the Composite Physical Function scale, whereas physical fitness was assessed using the Senior Fitness Test battery.
The 60-79-year-old females and males with SMI were more likely to have lower scores for lower and upper body strength, agility/dynamic balance, and aerobic endurance ( < 0.05) than those without SMI. The scores for lower and upper body flexibility in all age groups for both genders were not significant ( > 0.05). Binary logistic regression analysis revealed that old adults with SMI had a higher risk of losing physical independence later in life than those without SMI ( < 0.05).
This study showed that individuals with SMI have lower fitness levels and increased risk of losing physical independence than those without SMI.
我们研究了无症状心肌缺血（SMI）对60至79岁个体功能健康水平和身体独立性的影响。
我们对716名老年人进行了一项横断面研究，并使用心电图仪和动态心电图诊断患有SMI的人。使用综合身体功能量表评估身体独立性，而使用老年人健身测试组合评估身体健康状况。
与没有SMI的60至79岁女性和男性相比，患有SMI的人在下肢和上肢力量、敏捷性/动态平衡以及有氧耐力方面得分更低（P<0.05）。所有年龄组中男女的下肢和上肢柔韧性得分均无统计学意义（P>0.05）。二元逻辑回归分析显示，患有SMI的老年人在晚年失去身体独立性的风险高于没有SMI的人（P<0.05）。
这项研究表明，与没有SMI的人相比，患有SMI的人健康水平较低，失去身体独立性的风险增加。
