E-cigarettes are promoted for smoking cessation due to their having lower toxicity than cigarettes, but they are often used recreationally and linked to cardiovascular, respiratory, and mental health risks. Clinicians must understand usage patterns and influencing factors to guide patients in reducing or quitting their use.
We surveyed consecutive cardiac inpatients admitted to the University of Ottawa Heart Institute between November 2019 and May 2020. Surveys were conducted in-person or via telephone. Descriptive statistics and logistic regression were used to examine factors associated with vaping status.
During the evaluation, 1616 cardiac patients were admitted and discharged; 124 (7.7%) were ineligible, and 403 (24.9%) refused or were unreachable. A total of 1089 (73.0%) completed the survey. Among them, 10.3% had ever vaped, and 5.5% were current vapers. Of ever-users, 66.1% used vaping to quit smoking. Adjusted analysis showed that younger age, tobacco co-use, secondhand exposure at home, and lower education levels were significantly associated with e-cigarette use.
This evaluation found a low overall rate of e-cigarette use among cardiac inpatients. However, e-cigarette use was more common among younger patients, tobacco users, and those exposed to tobacco or e-cigarettes at home. These factors highlight the importance of advising patients to reduce their exposure to tobacco and e-cigarettes in their home and social environments, as doing so may improve their chances of quitting. Incorporating future prospective research in additional populations and settings would help support the generalizability of these results and assess their impact on clinical outcomes.
电子烟因毒性低于香烟而被推广用于戒烟，但它们常被用于消遣，并与心血管、呼吸和心理健康风险相关联。临床医生必须了解其使用模式和影响因素，以指导患者减少或戒除电子烟。
我们对2019年11月至2020年5月期间入住渥太华大学心脏研究所的连续心脏科住院患者进行了调查。调查通过面对面或电话方式进行。使用描述性统计和逻辑回归来检查与电子烟使用状况相关的因素。
在评估期间，1616名心脏科患者入院并出院；124名（7.7%）不符合条件，403名（24.9%）拒绝参与或无法联系到。共有1089名（73.0%）完成了调查。其中，10.3%曾经使用过电子烟，5.5%为当前电子烟使用者。在曾经使用者中，66.1%使用电子烟来戒烟。校正分析显示，年龄较小、同时使用烟草、在家中接触二手烟以及教育水平较低与电子烟使用显著相关。
本次评估发现心脏科住院患者中电子烟总体使用率较低。然而，电子烟使用在年轻患者、烟草使用者以及在家中接触烟草或电子烟的人群中更为常见。这些因素凸显了建议患者减少在家中和社交环境中接触烟草和电子烟的重要性，因为这样做可能会提高他们戒烟的几率。纳入针对更多人群和环境的未来前瞻性研究将有助于支持这些结果的普遍性，并评估它们对临床结局的影响。
