Insights
Only 13% of patients quit smoking after an atherosclerotic cardiovascular disease (ASCVD) event. The type of ASCVD event impacts smoking cessation likelihood, highlighting the need for tailored interventions.
Area of Science:
- Cardiology
- Public Health
- Smoking Cessation Research
Background:
- The impact of specific atherosclerotic cardiovascular disease (ASCVD) event types on smoking cessation remains unclear.
- Understanding these differences is crucial for developing targeted cessation strategies.
Purpose of the Study:
- To investigate how different types of ASCVD events influence patients' likelihood of quitting smoking.
- To compare the association of various ASCVD events with smoking cessation rates.
Main Methods:
- Utilized data from the National Cardiovascular Data Registry (2013-2018) for current smokers.
- Analyzed smoking status changes after interim ASCVD events (myocardial infarction, PCI, CABG, stroke/TIA, PAD).
- Employed multivariable Cox models to assess the association between ASCVD event type and smoking cessation.
Main Results:
- Among patients experiencing an ASCVD event, 12.8% quit smoking.
- Myocardial infarction, coronary artery bypass graft, and stroke/transient ischemic attack were associated with higher smoking cessation likelihood.
- Compared to elective percutaneous coronary intervention or peripheral artery disease, these events showed a greater impact on cessation.
Conclusions:
- Smoking cessation rates after an ASCVD event are low (around 13%).
- The specific type of ASCVD event significantly influences a patient's decision to quit smoking.
- Patient-centered interventions are necessary to improve smoking cessation outcomes post-ASCVD event.
Background:
It is unclear how the type of an atherosclerotic cardiovascular disease (ASCVD) event potentially influences patients' likelihood of smoking cessation.
Methods:
Using 2013 to 2018 data from the US based National Cardiovascular Data Registry Practice Innovation and Clinical Excellence outpatient cardiac registry, we identified patients who were current smokers at a clinic visit and followed them over time for a subsequent ASCVD event. Self-reported smoking status was assessed at each consecutive visit and used to determine smoking cessation after each interim ASCVD event (myocardial infarction, percutaneous coronary intervention, coronary artery bypass graft, stroke/transient ischemic attack, peripheral artery disease). We constructed separate multivariable Cox models with nonproportional hazards to examine the association of each interim ASCVD event with smoking cessation, compared with not having an interim ASCVD event. We estimated the relative association of ASCVD event type with smoking cessation using contrast tests. Analyses were stratified by presence versus absence of ASCVD at baseline.
Results:
Across 530 cardiology practices, we identified 1 933 283 current smokers (mean age 62±15, male 54%, ASCVD at baseline 50%). Among the 322 743 patients who had an interim ASCVD event and were still smoking, 41 336 (12.8%) quit smoking by their first subsequent clinic visit, which was higher among those with baseline ASCVD (13.4%) as compared with those without baseline ASCVD (11.5%). Each type of ASCVD event was associated with an increased likelihood of smoking. Patients who had an myocardial infarction, underwent coronary artery bypass graft (hazard ratio, 1.60 [95% CI, 1.55-1.65]), or had a stroke or transient ischemic attack were more likely to quit smoking as compared with those who underwent elective percutaneous coronary intervention or had a new diagnosis of peripheral artery disease (hazard ratio, 1.20 [95% CI, 1.17-1.22]).
Conclusions:
Only 13% of patients reported smoking cessation after an ASCVD event, with the type of event being associated with the likelihood of smoking cessation, prompting the need for patient-centered interventions.
