Previous research has been equivocal as to the impact of smoking status on cardiovascular reactivity to challenge. In addition, little is known about patterns of cardiovascular response habituation-sensitization to repeated challenge, in either smokers or the general population as a whole. The present study sought to clarify whether smokers and non-smokers differ in cardiovascular reactivity to challenge, or in patterns of reactivity to repeated challenge. 28 smokers and 28 anthropometrically matched non-smokers underwent repeated cardiovascular reactivity assessment. Results suggest that smokers had higher diastolic blood pressure (DBP) than non-smokers, and that female non-smokers demonstrated DBP response sensitization. Findings highlight direct associations between smoking and cardiovascular reactivity of potential significance to the etiology of cardiovascular disease.
先前的研究对于吸烟状况对挑战的心血管反应的影响一直存在争议。此外，对于吸烟者或整个普通人群在重复挑战时的心血管反应习惯化-敏感化模式知之甚少。本研究旨在阐明吸烟者和不吸烟者在对挑战的心血管反应方面是否存在差异，或者在对重复挑战的反应模式方面是否存在差异。28 名吸烟者和 28 名体重指数匹配的不吸烟者接受了重复的心血管反应评估。结果表明，吸烟者的舒张压（DBP）高于不吸烟者，而女性不吸烟者表现出 DBP 反应敏感化。研究结果突出了吸烟与心血管反应之间的直接关联，这对心血管疾病的病因具有重要意义。
