"Vital exhaustion," characterized by fatigue, irritability, and demoralization, precedes new and recurrent coronary events. Biological mechanisms explaining this association are not fully understood. The objective was to investigate the relationship between vital exhaustion, lifestyle, and lipid profile. Vital exhaustion, smoking, body mass index (BMI), alcohol consumption, exercise capacity, and serum lipids were determined in 300 healthy women, aged 56.4 +/- 7.1 years. No statistically significant associations were found between vital exhaustion and lifestyle variables. Divided into quartiles, vital exhaustion was inversely related to high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 in a linear fashion after adjustment for age, BMI, exercise capacity, and alcohol consumption. A multivariate-adjusted vital exhaustion-score in the top quartile, as compared to one in the lowest, was associated with 12% lower HDL-C and 8% lower apolipoprotein A1 (p < .05). In conclusion, alterations in lipid metabolism may be a possible mediating mechanism between vital exhaustion and coronary heart disease. The impact of lifestyle variables was weak.
以疲劳、易怒和士气低落为特征的“活力耗竭”先于新发和复发性冠状动脉事件出现。解释这种关联的生物学机制尚未完全明确。目的是研究活力耗竭、生活方式和血脂谱之间的关系。对300名年龄在56.4±7.1岁的健康女性测定了活力耗竭、吸烟、体重指数(BMI)、饮酒、运动能力和血脂。活力耗竭与生活方式变量之间未发现统计学上的显著关联。按四分位数分组后,在对年龄、BMI、运动能力和饮酒进行校正后,活力耗竭与高密度脂蛋白胆固醇(HDL-C)和载脂蛋白A1呈线性负相关。与最低四分位数相比,最高四分位数的多变量校正活力耗竭评分与HDL-C降低12%和载脂蛋白A1降低8%相关(p<.05)。总之,脂质代谢改变可能是活力耗竭与冠心病之间的一种可能中介机制。生活方式变量的影响较弱。
