探讨确诊冠心病 (CHD) 的焦虑患者在一次急性有氧运动后状态焦虑的个体差异。 118 名患有焦虑症状的先天性心脏病患者参加了了解运动和艾司西酞普兰对冠心病焦虑患者的益处 (UNWIND) 临床试验，在症状限制运动跑台测试之前和之后使用 100 毫米视觉模拟量表评估他们的焦虑水平。许多运动（例如，峰值摄氧量、运动持续时间、最大心率、无氧阈值）和心理变量被检查作为运动反应的潜在预测因素。使用一般线性模型检查焦虑的变化及其与心理变量的关联。 50 名患者 (42%) 在跑步机运动测试后表示，相对于运动前的评分，焦虑有所减轻。虽然检查了许多因素，但区分那些报告焦虑症状减轻的人与那些保持不变或实际上报告焦虑增加的人的唯一因素是运动前视觉模拟量表焦虑评级较高。没有观察到性别、特质焦虑严重程度、焦虑障碍的存在、运动测试持续时间或年龄的差异。尽管检查了许多变量，但只有较高的基线焦虑才能将视觉模拟量表评分下降的人和焦虑保持不变或恶化的人区分开来。对急性运动的反应在多大程度上可以预测慢性运动的抗焦虑作用需要进一步研究。
To explore individual differences in state anxiety following a single, acute bout of aerobic exercise among anxious patients with diagnosed coronary heart disease (CHD). One hundred eighteen CHD patients with elevated symptoms of anxiety enrolled in the UNderstanding the Benefits of Exercise and Escitalopram in Anxious Patients WIth coroNary Heart Disease (UNWIND) clinical trial rated their level of anxiety using a 100-mm visual analog scale before and after a symptom-limited exercise treadmill test. A number of exercise (eg, peak oxygen uptake, exercise duration, maximum heart rate, anaerobic threshold) and psychological variables were examined as potential predictors of exercise response. Changes in anxiety and their association with psychological variables were examined using general linear models. Fifty patients (42%) rated a reduction in anxiety relative to their pre-exercise ratings following the exercise treadmill test. While a number of factors were examined, the only factor that distinguished those individuals who reported a reduction in anxiety symptoms compared with those who either remained the same or actually reported an increase in anxiety was a higher pre-exercise visual analog scale anxiety rating. No differences were observed as a function of sex, severity of trait anxiety, the presence of an anxiety disorder, exercise test duration, or age. Although many variables were examined, only higher baseline anxiety distinguished those who showed a reduction in their visual analog scale ratings from those whose anxiety remained the same or got worse. The extent to which the response to acute exercise predicts the anxiolytic effects of chronic exercise needs further study.
