24-hour hemodynamic and stiffness parameter data in smoking and non-smoking volunteers

The brachial diastolic (DBPbr) and systolic blood pressure (SBPbr), heart rate (PULSE), aortic systolic blood pressure (SBPao), aortic augmentation index (AIXao), brachial augmentation index (AIXbr) and pulse wave velocity (PWV) were recorded and mean arterial pressure (MAP) and pulse pressure (PP) were calculated in every 20 minutes during waking and in every 40 minutes during sleeping hours with an oscillometric device. Volunteers abstained from smoking during the first 24 hours and were allowed to smoke during the second 24 hours (at least 10 cigarettes). Afterwards, data was obtained with the same method from 10 healthy, non-smoker, age-matched and BMI-matched volunteers. All participants abstained from alcohol-containing beverages and physical exertion outside normal daily activities during the examined period. Day and night periods were adjusted individually. Invalid data were eliminated resulting in an average of 46 remaining values per day per parameter.
In the dataset nighttime hours were highlighted with grey and a thick black line represented the end of the first (non-smoking) day among light smokers.

本研究采用示波设备，于清醒时段每20分钟、睡眠时段每40分钟，记录肱动脉舒张压（DBPbr）、肱动脉收缩压（SBPbr）、心率（PULSE）、主动脉收缩压（SBPao）、主动脉增强指数（AIXao）、肱动脉增强指数（AIXbr）与脉搏波速度（PWV），并计算得到平均动脉压（MAP）与脉压（PP）。受试者在前24小时内需禁烟，后24小时内可吸烟，累计至少10支。后续采用相同方法，对10名健康非吸烟、年龄与体重指数（BMI）匹配的受试者开展数据采集。所有受试者在研究期间均需禁酒，且不得进行超出日常常规活动的体力运动或劳作。昼夜时段均经个体化调整。剔除无效数据后，各参数每日平均剩余46条有效观测值。
本数据集以灰色高亮标注夜间时段，且以粗黑线标示轻度吸烟者首个（禁烟）阶段的结束时刻。
