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.
