Depression: a predictor of smoking relapse in a 6-month follow-up after hospitalization for acute coronary syndrome

Smoking cessation and depression after acute coronary syndrome

Smoking and depression are risk factors for acute coronary syndrome (ACS) that often co-exist. We investigated the evolution of depression according to smoking cessation one-year after ACS. Data from 1822 ACS patients of the Swiss multicenter SPUM-ACS cohort study were analyzed over a one-year follow-up. Participants were classified in three groups based on smoking status one-year post-ACS - continuous smokers, smokers who quit within the year, and non-smokers. Depression status at baseline and one-year was assessed with the Center for Epidemiologic Studies Depression scale (CES-D) and antidepressant drug use. A CES-D score ≥ 16 defined depression. A multivariate-adjusted logistic regression model was used to calculate odds ratios (OR) between groups. The study sample mean age was 62.4 years and females represented 20.8%. At baseline, 22.6% were depressed, 40.9% were smokers, and 47.5% of these quit smoking over the year post-ACS. In comparison to depressed continuous smokers, depressed smokers who quit had an adjusted OR 2.59 (95% confidence interval (CI) 1.27-5.25) of going below a CES-D score of 16 or not using antidepressants. New depression at one-year was found in 24.4% of non-depressed smokers who quit, and in 27.1% of non-depressed continuous smokers, with an adjusted OR 0.85 (95% CI 0.55-1.29) of moving to a CES-D score of ≥16 or using antidepressants. In conclusion, smokers with depression at time of ACS who quit smoking improved their depression more frequently compared to continuous smokers. The incidence of new depression among smokers who quit after ACS was similar compared to continuous smokers.

Smoking cessation after acute coronary syndrome: A systematic review and meta-analysis

BACKGROUND

Smoking cessation is an effective secondary prevention measure after acute coronary syndrome (ACS). We conducted a systematic review with the aim to better understand which patients have a greater propensity to quit smoking and the risk factors for continued smoking after ACS.

METHODS

We searched MEDLINE and EMBASE for studies that evaluated smoking cessation after ACS. The pooled rate of smoking cessation across included studies was performed. Random effects meta-analysis for different variables and their association with smoking cessation was conducted.

RESULTS

A total of 39 studies with 11 228 patients were included in this review. The pooled rate of smoking cessation following ACS across 38 studies was 45.0%. Factors associated with greater likelihood of smoking cessation were attendance at cardiac rehabilitation (OR 1.90 95% CI 1.44-2.51), married/not alone (OR 1.68 95% CI 1.32-2.13), intention/attempt to quit smoking (OR 1.27 95% CI 1.11-1.46), diabetes mellitus (OR 1.24 95% CI 1.03-1.51) and hospitalised duration (OR 1.09 95% CI 1.02-1.15). Variables associated with a lower likelihood of smoking cessation were depression (OR 0.57 95% CI 0.43-0.75), chronic obstructive pulmonary disease/lung disease (OR 0.73 95% CI 0.57-0.93), previous admission with acute myocardial infarction/cardiac admission (OR 0.61 95% CI 0.47-0.80), cerebrovascular disease/transient ischaemic attack (OR 0.42 95% CI 0.30-0.58) and unemployment (OR 0.37 95% CI 0.17-0.80).

CONCLUSIONS

The majority of smokers with an ACS continue to smoke after admission. Patients attending cardiac rehabilitation show increased odds of quitting while people who are depressed and those with chronic lung disease were less likely to quit smoking and should be targeted for intensive smoking cessation interventions.

Parental divorce and offspring smoking and alcohol use: a systematic review and meta-analysis of observational studies

This study was conducted to investigate the relationship between parental divorce and smoking and alcohol consumption in offspring, which is based on a systematic review method and ultimately meta-analysis. Method: In a systematic search, three databases were selected. The manuscripts were searched based on the keywords and the time limit for the search was published manuscripts in English until November 2020. For the relationship between parental divorce and smoking/alcohol use in offspring, one main analysis, and four analyses based on sex, study design, adjusted level, and continents were performed. Result: Forty-three studies were synthesized from the collection of manuscripts. The odds of smoking in offspring whose parents were separated was 1.45 (CI 1.37-1.54) and this odds in men was equal to 1.38 (CI 1.11-1.71; Z = 2.91; p = 0.004; I2 = 81.5%) and in women, 1.78 (CI 1.51-2.10; Z = 6.88; p < 0.001; I2 = 69.6%). The odds of alcohol use in offspring whose parents were separated was 1.43 (CI 1.15-1.77) and this odds in men was equal to 1.69 (CI 1.16-2.47; Z = 2.73; p = 0.006; I2 = 99.6%) and in women 1.79 (CI 1.07-2.99). Discussion: The findings of the present study can be used in health-related policies, prevention, and clinical interventions. This study was a subject with limitations, also.

Symptoms of depression and active smoking among survivors of stroke and myocardial infarction: An NHANES analysis

Historic concerns about the cardiovascular and neuropsychiatric side effects of smoking-cessation pharmacotherapy have in part limited their use. We sought to evaluate whether depressive symptoms are associated with active smoking among survivors of stroke and myocardial infarction (MI). To do this, we performed a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (2005-2016). We included participants ≥20 years old with prior stroke or MI and any history of smoking. Symptoms of depression, at survey participation, were ascertained using the Patient Health Questionnaire-9. Active smoking was defined using self-report and, secondarily, with cotinine measures. We used logistic regression to evaluate the association between depression and active smoking after adjusting for demographics, smoking-related medical conditions, and health-related behaviors. We found that, among stroke and MI survivors with any history of smoking, 37.9% (95% CI, 34.5-41.3%) reported active smoking and 43.8% (95% CI, 40.3-47.3%) had biochemical evidence of smoking. Rates of active smoking were similar for stroke and MI survivors. Twenty-one percent screened positive for depression. In adjusted models, depression was associated with active smoking in the combined group of stroke and MI survivors (odds ratio, 2.28; 95% CI, 1.24-4.20) and in stroke survivors (odds ratio, 2.97; 95% CI, 1.20-7.38). Tests of heterogeneity by event type did not reveal an interaction. Findings were similar when using cotinine measures. We conclude that symptoms of depression were associated with active smoking among stroke and MI survivors. Stroke and MI survivors with symptoms of depression may require targeted smoking-cessation interventions.

Smoking-cessation pharmacotherapy for patients with stroke and TIA: Systematic review

Data regarding the efficacy and safety of smoking-cessation pharmacotherapy after stroke are lacking. We systematically reviewed data on this topic by searching Medline, Cochrane, and Clinicaltrials.gov to identify randomized clinical trials (RCT) and observational studies that assessed the efficacy and safety of nicotine replacement therapy (NRT), varenicline, and bupropion in patients with stroke and TIA. We included studies that reported rates of smoking cessation, worsening or recurrent cerebrovascular disease, seizures, or neuropsychiatric events. We identified 2 RCTs and 6 observational studies; 3 included ischemic stroke and TIA, 2 subarachnoid hemorrhage (SAH), and 3 did not specify. Four studies assessed efficacy; cessation rates ranged from 33% to 66% with pharmacological therapy combined with behavioral interventions versus 15% to 46% without, but no individual study demonstrated a statistically significant benefit. Safety data for varenicline and buopropion in ischemic stroke were scarce. Patients with SAH who received NRT had more seizures (9% vs 2%; P = 0.024) and delirium (19% vs 7%; P = 0.006) in one study, but less frequent vasospasm in 3 studies. In conclusion, combined with behavioral interventions, smoking-cessation therapies resulted in numerically higher cessation rates. Limited safety data may prompt caution regarding seizures and delirium in patients with subarachnoid hemorrhage.

Anxiety and Depression After a Cardiac Event: Prevalence and Predictors

Introduction

Patients who are anxious or depressed after an acute cardiac event are at increased risk of a subsequent event and premature death. It is therefore important to identify these patients early in order to initiate supportive or even preventive measures. In the present study, we report on the prevalence of anxiety and depression during the first 12 months after an acute cardiac event, and the patient characteristics predictive of increased anxiety and depression risk in early and late convalescence.

Methods

We recruited a sample of 911 patients with acute myocardial infarction (AMI), acute coronary syndrome (ACS), and/or unstable angina (UA), and/or undergoing coronary artery bypass graft surgery (CABGS). Patients completed the Hospital Anxiety and Depression Scale (HADS) close to the time of their event, and again during early (2–4 months post-event) and late (6–12 months post-event) convalescence. Using HADS-A and HADS-D cut-offs of 8+, prevalence rates for anxiety, depression, and comorbid anxiety and depression were determined for each timepoint. Chi-square tests and odds ratios were used to identify baseline patient characteristics associated with increased anxiety and depression risk over 12 months.

Results

Anxiety rates were 43, 28, and 27% at the time of the event, early, and late convalescence. Depression rates were 22, 17, and 15%, respectively. Factors consistently associated with increased anxiety and depression risk were history of depression, financial strain, poor self-rated health, low socioeconomic status, younger age (<55 years), and smoking. Obesity, diabetes, and social isolation (living alone or being unpartnered) were identified as important albeit less significant risk factors. Neither sex nor event type were predictive of anxiety or depression.

Conclusion

This large patient sample provided the opportunity to identify rates of anxiety and depression during the 12 months after a cardiac event and key patient characteristics for increased risk. These risk factors are easily identifiable at the time of the event, and could be used to guide the targeting of support programs for patients at risk.

Effects of post-discharge counseling and medication utilization on short and long-term smoking cessation among hospitalized patients

Numerous studies have tested the effect of multicomponent post-discharge smoking cessation interventions on post-discharge smoking cessation, and many are effective. However, little is known regarding the relative efficacy of the different intervention components on short or long-term cessation. The present study is a secondary analysis (n = 984) of a randomized controlled trial for hospitalized smokers that took place at two large hospitals in Kansas from 2011 to 2014. All study participants were offered post-discharge quitline services. Pharmacotherapy was recommended during bedside tobacco treatment. The study outcomes were self-reported cessation at 1-month and biochemically verified cessation at 6-months post-randomization. During the post-discharge period, 69% of participants completed at least one quitline call and 28% of participants reported using cessation pharmacotherapy. After controlling for known predictors of cessation among hospitalized smokers, both the number of total quitline calls completed post-discharge and use of cessation pharmacotherapy post-discharge were predictive of cessation at 1-month. After accounting for predictors of cessation and quitting at 1-month, total post-discharge quitline calls was associated with cessation at 6-months (OR [95% CI] = 1.23 [1.12, 1.35], p < 0.001) while post-discharge cessation pharmacotherapy use was not. The results suggest that both engagement in quitline services and use pharmacotherapy independently facilitate cessation beyond the influence of known clinical characteristics associated with cessation. Over the longer term, the effect of engaging in quitline services persists while the effect of pharmacotherapy diminishes. To optimize outcomes, future research should investigate methods to increase utilization of medications and promote sustained counseling engagement in order to sustain the effects of treatment during the post-discharge period.

•

Counseling and pharmacotherapy are effective interventions for helping hospitalized smokers quit smoking, but the relative contribution of each intervention component to short or long-term abstinence is not well understood

•

This secondary analysis of a large clinical trial found that quitline counseling and pharmacotherapy – when used after hospital discharge - were associated with increased odds of quitting smoking at 1-month follow up

•

Controlling for early abstinence at 1 month, only post-discharge quitline counseling remained predictive of cessation at 6-months follow-up

•

Pharmacotherapy and quitline counseling independently facilitate short-term abstinence, while long-term abstinence is facilitated by engagement in quitline counseling services

•

Hospitals could work directly with state quitlines to integrate counseling into post-discharge care

A randomized trial of decision support for tobacco dependence treatment in an inpatient electronic medical record: clinical results

BACKGROUND

Smokers usually abstain from tobacco while hospitalized but relapse after discharge. Inpatient interventions may encourage sustained quitting. We previously demonstrated that a decision support tool embedded in an electronic health record (EHR) improved physicians' treatment of hospitalized smokers. This report describes the effect on quit rates of this decision support tool and order set for hospitalized smokers.

METHODS

In a single hospital system, 254 physicians were randomized 1:1 to receive a decision support tool and order set, embedded in the EHR. When an adult patient was admitted to a medical service, an electronic alert appeared if current smoking was recorded in the EHR. For physicians receiving the intervention, the alert linked to an order set for tobacco treatment medications and electronic referral to the state tobacco quitline. Additionally, "Tobacco Use Disorder" was added to the patient's problem list, and a secure message was sent to the patient's primary care provider (PCP). In the control arm, no alert appeared. Patients were contacted by phone at 1, 6, and 12 months; those reporting tobacco abstinence at 12 months were asked to return to measure exhaled carbon monoxide. Generalized estimating equations were used to model the data.

RESULTS

From 2013 to 2016, the alert fired for 10,939 patients (5391 intervention, 5548 control). Compared to control physicians, intervention physicians were more likely to order tobacco treatment medication, populate the problem list with tobacco use disorder, refer to the quitline, and notify the patient's PCP. In a subset of 1044 patients recruited for intensive follow-up, one-year quit rates for intervention and control patients were, respectively, 11.5% and 11.6%, (p = 0.94), after controlling for age, sex, race, ethnicity, and insurance. Similarly, there were no differences in 1- and 6-month quit rates.

CONCLUSIONS

Although we were able to improve processes of care, long-term tobacco quit rates were unchanged. This likely reflects, in part, the need for sustained quitting interventions, and higher-than-expected quit rates in controls. Future enhancements should improve prescription of medications for smoking cessation at discharge, engagement of primary care providers, and perhaps direct engagement of patients in a more longitudinal approach.

Does outpatient cardiac rehabilitation help patients with acute myocardial infarction quit smoking?

Outpatient cardiac rehabilitation (OCR) reinforces patients' efforts to quit smoking, but the association between participation in OCR and long-term smoking status after acute myocardial infarction (AMI) is unknown. We studied hospitalized smokers with confirmed AMI from two multicenter prospective registries (PREMIER, from January 1, 2003, to June 28, 2004, and TRIUMPH, from April 11, 2005, to December 31, 2008) to describe the association of OCR participation with smoking cessation. Eligible patients smoked at least 1 cigarette per day on average in the 30 days prior to enrollment and completed 12-month follow-up (N = 1307). Structured interviews were completed on subjects at baseline and during follow-up. OCR participation and abstinence from smoking within the prior 30-days (30-day point prevalence abstinence, PPA) were self-reported. We constructed a propensity model of OCR participation based on 22 baseline sociodemographic and clinical characteristics, and constructed hierarchical modified Poisson regression models of 30-day PPA at 12 months after matching on the propensity for OCR participation (with clinical site treated as a random effect). Seventy-four percent of subjects were referred to OCR at hospital discharge, but only 36% participated during follow-up. At 12-month follow-up, 30-day PPA was 57% in OCR participants, compared to 41% in matched OCR non-participants. Participation in OCR was a significant predictor of 30-day PPA at 12 months (adjusted RR 1.38, 95% CI 1.20-1.57). In conclusion, smokers who participated in OCR were significantly more likely to abstain from smoking 12 months after AMI hospitalization.

Predictors of smoking relapse after percutaneous coronary intervention in Chinese patients

AIMS AND OBJECTIVES

To evaluate the prevalence and predictors of smoking relapse after percutaneous coronary intervention in Chinese patients.

BACKGROUND

Smoking is considered a vital risk factor for coronary heart disease. Although smoking cessation could decrease the risks of adverse cardiac outcomes, many patients resume smoking following a short period of abstinence. However, little is known about smoking resumption in patients who have undergone percutaneous coronary intervention.

DESIGN AND METHODS

A longitudinal study was conducted among Chinese patients who underwent percutaneous coronary intervention. Predictive variables were assessed at baseline through medical records and interviews with questionnaires including the Fagerström Test for Nicotine Dependence, Center for Epidemiologic Studies-Depression scale and Smoking Self-Efficacy Questionnaire. Smoking relapses were recorded at three, six, nine and 12 months by the self-reporting through telephone or at routine visits to the cardiology outpatient clinics.

RESULTS

A total of 221 patients who quit smoking immediately after percutaneous coronary intervention completed the whole study. Overall, 51.1%(n = 113) of the patients relapsed within 12 months after percutaneous coronary intervention. The prevalence showed a particular rise (49.6%, n = 56) in the first 3 months and a more gradual increase in the following months. The patients who were employed and had higher nicotine dependence, worse depressive symptoms and lower level of smoking self-efficacy were more vulnerable to relapse to cigarettes.

CONCLUSION

The prevalence of smoking relapse is high in the patients who stop smoking in the hospital due to percutaneous coronary intervention. The predictors of smoking relapse are employment, nicotine dependence, depression and smoking self-efficacy in the post- percutaneous coronary intervention patients.

RELEVANCE TO CLINICAL PRACTICE

This study may prompt the healthcare providers to focus on the issue of smoking relapse and provide some instructions for identification of the patients with a high-risk of relapse after percutaneous coronary intervention.

Smoking Abstinence Twelve Months after an Acute Coronary Syndrome

Studies on the cognitive working mechanism of smoking cessation in high-risk populations are few and much needed, and identifying long-term psychosocial factors to smoking cessation are relevant to improve intervention for cardiac patient groups. This longitudinal study followed patients who smoked and suffered an acute coronary syndrome from hospitalization to 12 months after clinical discharge. Questionnaires were administered to assess nicotine dependence, behavioral dependence, autonomous self-regulation, perceived competence, social support, anxiety, depressive symptoms and meaning in life at baseline, six months and twelve months after clinical discharge. The results showed that anxiety (F(2, 62) = 28.10, p < .001, η p 2 = .48) and depressive symptoms (F(2, 62) = 10.42, p < .001, η p 2 = .25) decreased over time, whereas meaning in life (F(2, 61) = 44.77, p < .001, η p 2 = .59) and social support increased (t(63) = -4.54, p < .001, 95% IC[-11.05, 4.29], η2 =.25). Smoking dependence was negatively predicted by change in perceived competence (B = -2.25, p = .011, 95% IC[.02, .60]) and positively by change in depressive symptoms (B =.37, p = .042, 95% IC[1.01, 2.05]) 12 months after clinical discharge. Nicotine dependence (t(17) = 2.76, p = .014, 95% IC[.39, 2.94], η2 =.31) and the number of cigarettes smoked per day (t(17) = 4.48, p < .001, 95% IC[5.49, 15.29], η2 =.54) decreased over time, whereas behavioral dependence increased among smokers (t(17) = -2.37, p = .030, 95% IC[-4.30, 2.54], η2 =.25). This study suggests that long term abstinence in cardiac patients may be enhanced by psychological interventions addressing perceived competence, depressive symptoms and behavioral dependence.

Anger Expression Style Predicts the Domain of the First Smoking Relapse After a Quit Attempt

BACKGROUND

Risk for smoking relapse may be associated with context-dependent social and behavioral cues. However, lack of research examining the role of trait negative mood such as anger in this relationship and assessment of objective indices related to smoking status (e.g., biochemical measures) may limit existing findings. We examined the roles of trait anger, habitual anger expression behavior, and the situation in which the first incident of smoking lapse following a quit attempt occurs.

METHODS

One-hundred and five smokers interested in cessation (mean age, SD: 34.7 ± 11.8) set a quit day and attended multiple post-quit assessments where they were asked to provide biochemical measures including exhaled carbon monoxide (CO) and self-report measurements, including smoking status.

RESULTS

Eighty-eight participants (40 women) returned to smoking over the 12-month study period. Self-reported smoking status was verified by exhaled CO measurements. Thirty-one percent of participants who relapsed reported the first lapse occurring at home, 15% at work, 14% at a restaurant or a bar, and 8% in a car. Multinomial logistic regression models found that high levels of anger-out were associated with smoking relapse in situations other than work or home (p <.05).

CONCLUSIONS

These results expand prior work suggesting habitual anger expression style may moderate associations between situational factors and risk for smoking relapse, highlighting the need to incorporate findings in treatment methods. Absence of gender differences suggests the situational factors explored here affect relapse independent of gender.

Self-Reporting of Smoking Cessation in Cardiac Patients: How Reliable Is It and Is Reliability Associated With Patient Characteristics?

OBJECTIVES

The objectives of this study were to determine the accuracy of smoking cessation self-reports by cardiac patients who participated in a smoking cessation program, and to determine which patient characteristics are associated with an inaccurate self-report during a follow-up interview 12 months after the start of the program.

METHODS

Smoking cessation self-reports (point prevalence abstinence) were validated against salivary cotinine levels. Using χ analyses, patients who reported accurately being a nonsmoker were compared with those who reported inaccurately being a nonsmoker (biochemically verified as smokers) on factors the literature has indicated to be associated with inaccurate self-report in smoking. Potential predictors of inaccurate self-report of smoking (P ≤ 0.20 in univariate analyses) were subsequently tested in a multivariate logistic regression analysis.

RESULTS

Of the 95 patients tested, almost 25% inaccurately reported having quit smoking at a cutoff of 10-ng/mL cotinine in saliva. The data show more underreporting of smoking among patients who received a face-to-face counseling intervention and among patients with an intermediate education level. There was significantly less underreporting among patients characterized as having a Type D personality.

CONCLUSIONS

These findings suggest that underreporting of smoking status in cardiac patients who participate in a smoking cessation program is high, especially in those who receive intensive face-to-face counseling. Having a Type D personality seems to be a protective factor, whereas having an intermediate level of education is a risk factor for inaccurate reporting. Biochemical validation in high-risk populations is highly needed, ideally accompanied by alternative forms of verification. Optimal validation testing in smoking cessation studies of cardiac patients is difficult because of high refusal rates, no-show, and organizational difficulties.

Trajectories of smoking behavior as a function of mood and satisfaction with life: What matters most?

BACKGROUND

Worldwide, tobacco use causes more than 5 million deaths per year. The present study investigated possible preventative factors of nicotine dependence, such as mood and Satisfaction With Life (SWL).

METHODS

Longitudinal Internet survey of 1957 individuals assessed three times at a two week interval (2007-2010).

OUTCOME MEASURES

Cigarette Dependence Scale (CDS), feeling prisoner to cigarettes, smoking cessation, reduction, and relapse.

PREDICTORS

Time (i.e. trajectory of dependence over time), smoking status (daily, occasional or ex-smoker), mood, and SWL. All measures were assessed at each time point.

RESULTS

Both SWL, and mood, respectively were significantly associated with dependence (slopeSWL=-0.03, slopeSWL=-0.11, ps<0.001). With respect to feeling prisoner to cigarettes, mood but not SWL showed a significant association (slopeSWL=-0.14, p<0.001). Occasional, and ex-smokers showed significantly greater decrease in psychological dependence, as mood increased, than daily smokers (slopeoccasional=-0.28, poccasional=0.011; slopeex=-0.27, pex<0.001). Smoking cessation decreased over time, and both mood, as well as SWL had a significant impact on cessation (ORmood=1.43, pmood<0.01, ORSWL=1.15, pSWL=0.042). Reduction in smoking was predicted by SWL only (ORSWL=1.21, p=0.043), whereas relapse was predicted by mood only (ORmood=0.55, p<0.01).

LIMITATIONS

The participants were self-selected. Possible confounding relationships (e.g., medication) have to be further assessed.

CONCLUSIONS

Cigarette dependence, feeling prisoner to cigarettes, cessation, and reduction are significantly influenced by both mood and SWL. Treatments may thus tackle mood regulation, SWL, and nicotine dependence in tandem.

Anxiety and adverse health outcomes among cardiac patients: a biobehavioral model

BACKGROUND

Anxiety is a common experience among patients with acute coronary syndrome (ACS) that can have a negative impact on health outcomes. Nonetheless, the negative role of anxiety remains underappreciated, as reflected by clinicians' underrecognition and undertreatment of anxious hospitalized and nonhospitalized patients with ACS. Underappreciation of the role of anxiety is possibly related to inadequate understanding of the mechanisms whereby anxiety may adversely affect health outcomes.

PURPOSE

The aim of this study was to synthesize the evidence about potential mechanisms by which anxiety and adverse health outcomes are related.

CONCLUSIONS

A biobehavioral model links anxiety to the development of thrombogenic and arrhythmic events in patients with ACS. Biologically, anxiety may interfere with the immune system, lipid profile, automatic nervous system balance, and the coagulation cascade, whereas behaviorally, anxiety may adversely affect adoption of healthy habits and cardiac risk-reducing behaviors. The biological and behavioral pathways complement each other in the production of poor outcomes.

CLINICAL IMPLICATIONS

Anxiety requires more attention from clinical cardiology. The adverse impact of anxiety on health outcomes could be avoided by efficient assessment and treatment of anxiety.

Systematic review and meta-analysis of the impact of depression on subsequent smoking cessation in patients with coronary heart disease: 1990 to 2013

OBJECTIVE

Smoking cessation is crucial for patients with coronary heart disease (CHD), yet depression may impede cessation success. We systematically reviewed the prospective association between depression and subsequent smoking cessation in individuals with CHD to quantify this effect.

METHODS

Electronic databases (PsychInfo, PubMed, CINAHL) were searched for prospective studies of patients with CHD that measured depression at baseline (scales, diagnostic interview, or antidepressant prescription) and reported smoking continuation/cessation at follow-up. Inclusive dates were January 1, 1990, to May 22, 2013. Standardized mean differences (SMDs) and associated 95% confidence intervals were estimated using random-effects meta-analysis. Sensitivity analysis explored the impact of limiting meta-analysis to studies using different depression measures (validated scales, diagnostic interviews, antidepressant prescription), different durations of follow-up, or higher-quality studies.

RESULTS

From 1185 citations retrieved, 28 relevant articles were identified. Meta-analysis of all available data from 20 unique data sets found that depressed patients with CHD were significantly less likely to quit smoking at follow-up (SMD = -0.39, 95% confidence interval = -0.50 to -0.29; I(2) = 51.2%, p = .005). Estimates remained largely unchanged for each sensitivity analysis, except for two studies that used antidepressants, which showed a much larger effect (SMD = -0.94, -1.38 to -0.51; I(2) = 57.7%, p = .124).

CONCLUSIONS

Patients with CHD and depressive symptoms are significantly less likely to quit smoking than their nondepressed counterparts. This may have implications for cardiovascular prognosis, and CHD smokers may require aggressive depression treatment to enhance their chances of quitting.

The prevalence and correlates of single cigarette selling among urban disadvantaged drug users in Baltimore, Maryland

BACKGROUND

Selling of single cigarettes, also known as loosies, is a public health concern. Loosies allow for those with fewer resources to buy cigarettes without having to purchase a pack. Selling of loosies may cue smoking behaviors. In the US, socioeconomically disadvantaged populations have high rates of smoking and illicit drug use and the selling of loosies appears to be linked to the urban informal economy. We examined the proportion and frequency of cigarette selling and roles in the informal economy associated with selling loosies among a sample of urban drug users.

METHODS

There were 801 participants, recruited by community outreach, assessed at baseline, who were enrolled in an HIV prevention intervention for drug users.

RESULTS

Most (89%) smoked cigarettes in the prior 30 days, of whom 92% smoked daily. Self-reported selling of cigarettes was common with 58% reporting that they had sold cigarettes within the last six months; 20.4% reported selling cigarettes a few times a week and 7.4% reported daily selling of cigarettes. In a stepwise regression model, four sources of income were associated with frequent cigarette selling: providing street security (OR=2.214, 95% CI 1.177-4.164), selling food stamps (OR=1.461, 95% CI 1.003-2.126), pawning items (OR=2.15, 95% CI 1.475-3.135), and selling drugs (OR=1.634, 95% CI 1.008-2.648).

CONCLUSION

There is a high rate of selling loosies among urban substance users. The wide availability of loosies may promote smoking. Smoking cessation programs with drug treatment and economic development programs may help to reduce economic pressures to sell loosies.

Development and Alpha Testing of QuitIT: An Interactive Video Game to Enhance Skills for Coping With Smoking Urges

BACKGROUND

Despite many efforts at developing relapse prevention interventions, most smokers relapse to tobacco use within a few months after quitting. Interactive games offer a novel strategy for helping people develop the skills required for successful tobacco cessation.

OBJECTIVE

The objective of our study was to develop a video game that enables smokers to practice strategies for coping with smoking urges and maintaining smoking abstinence. Our team of game designers and clinical psychologists are creating a video game that integrates the principles of smoking behavior change and relapse prevention. We have reported the results of expert and end-user feedback on an alpha version of the game.

METHODS

The alpha version of the game consisted of a smoking cue scenario often encountered by smokers. We recruited 5 experts in tobacco cessation research and 20 current and former smokers, who each played through the scenario. Mixed methods were used to gather feedback on the relevance of cessation content and usability of the game modality.

RESULTS

End-users rated the interface from 3.0 to 4.6/5 in terms of ease of use and from 2.9 to 4.1/5 in terms of helpfulness of cessation content. Qualitative themes showed several user suggestions for improving the user interface, pacing, and diversity of the game characters. In addition, the users confirmed a high degree of game immersion, identification with the characters and situations, and appreciation for the multiple opportunities to practice coping strategies.

CONCLUSIONS

This study highlights the procedures for translating behavioral principles into a game dynamic and shows that our prototype has a strong potential for engaging smokers. A video game modality exemplifies problem-based learning strategies for tobacco cessation and is an innovative step in behavioral management of tobacco use.

Effectiveness of a telephone delivered and a face-to-face delivered counseling intervention for smoking cessation in patients with coronary heart disease: a 6-month follow-up

Smoking cessation interventions for cardiac patients need improvement given their weak effects on long-term abstinence rates and low compliance by nurses to implementation. This study tested the effectiveness of two smoking cessation interventions against usual care in cardiac patients, and conditional effects for patients' motivation to quit and socio-economic status (SES). An experimental study was conducted from 2009 to 2012 for which Dutch cardiac patient smokers were assigned to: usual care (UC; n = 245), telephone counseling (TC; n = 223) or face-to-face counseling (FC; n = 157). The three groups were comparable at baseline and had smoked on average 21 cigarettes a day before hospitalization. After six months, interviews occurred to assess self-reported smoking status. Patients in the TC and FC group had significantly higher smoking abstinence rates than patients in the UC group (p ≤ 0.05 at all times). Regression analysis further revealed significant conditional effects of the interventions on smoking abstinence in patients with lower SES, with a larger effect for TC than FC when compared to UC. These findings suggest that intensive counseling is effective in increasing short-term abstinence rates, particularly in patients with lower SES. Future studies need to investigate how patients with higher SES can profit equally from these type of interventions.

Depressive symptoms among heavy cigarette smokers: the influence of daily rate, gender, and race

INTRODUCTION

Cigarette smokers experience higher levels of depressive symptoms and are more likely to be diagnosed with depressive disorders than nonsmokers. To date, the nature of the smoking-depression relationship has not been adequately studied among heavy smokers, a group at elevated risk for poor health outcomes. In this study, we examined depressive symptom expression among heavy smokers while considering the moderating roles of smoking status, gender, and race. We also explored whether amount of tobacco usually consumed had an impact.

METHODS

We extracted data from a large, highly nicotine-dependent, nontreatment cigarette smoking study sample (N = 6,158). Participants who consented were screened for major exclusions, and they completed questionnaires.

RESULTS

Smokers reported a higher, clinically meaningful level of depressive symptoms relative to nonsmokers (27.3% of smokers vs. 12.5% of nonsmokers) scored above the clinical cutoff on the Center for Epidemiological Studies Depression (CES-D) scale (p < .001), which differed among race × gender subgroups. Further, amount of daily intake was inversely associated with self-report of depressive symptoms. For every 10-cigarette increment, the likelihood of scoring above the CES-D clinical cutoff decreased by 62% (p < .0001).

CONCLUSIONS

These findings improve our understanding of tobacco's influence on depressive symptom expression among heavy smokers, with implications for tailoring evidence-based tobacco treatments.

Predictors of smoking patterns after first stroke

Persistent smoking following stroke is associated with poor outcomes including development of secondary stroke and increased mortality risk. This study uses longitudinal data from the U.S. Health and Retirement Study (1992-2008) to investigate whether depression and duration of inpatient hospital care impact smoking outcomes among stroke survivors (N = 745). Longer duration of care was associated with lower likelihood of persistent smoking. Depression was associated with greater cigarette consumption. Interaction effects were also significant, indicating that for survivors who experienced longer inpatient care there was a weaker association between depression and cigarette consumption. Implications for practice and research are discussed.

Smoking cue reactivity in adult smokers with and without depression: a pilot study

Little is known about the relationship between Major Depressive Disorder (MDD) and smoking-related behaviors such as cue-induced urges to smoke. The purpose of this pilot study was to examine: (1) differences in smoking cue reactivity by MDD history and (2) the association of a diagnosis of MDD, current depressive symptoms, and smoking variables to cue-induced urges to smoke. Participants (N = 52) were n = 31 smokers with no MDD history and n = 21 smokers with past MDD. Participants completed a 2-hour laboratory session during which they were exposed to neutral (eg, pencils) and smoking cues (eg, cigarettes) after smoking one of their preferred brand cigarettes (Satiated Condition) and when it had been 1 hour since they smoked (Brief Deprivation Condition). Cue-induced urges increased with exposure to smoking cues and this increase did not significantly differ by diagnosis group. Current symptoms of depression, but not a diagnosis of MDD, were significantly and positively related to cue-induced cravings in satiated adult smokers. The association between depression symptoms and smoking urges was not significant in the Brief Deprivation Condition. Smoking cue reactivity may be a useful procedure for studying aspects of smoking behavior in adults with depression.

Effectiveness of two intensive treatment methods for smoking cessation and relapse prevention in patients with coronary heart disease: study protocol and baseline description

BACKGROUND

There is no more effective intervention for secondary prevention of coronary heart disease than smoking cessation. Yet, evidence about the (cost-)effectiveness of smoking cessation treatment methods for cardiac inpatients that also suit nursing practice is scarce. This protocol describes the design of a study on the (cost-)effectiveness of two intensive smoking cessation interventions for hospitalised cardiac patients as well as first results on the inclusion rates and the characteristics of the study population.

METHODS/DESIGN

An experimental study design is used in eight cardiac wards of hospitals throughout the Netherlands to assess the (cost-)effectiveness of two intensive smoking cessation counselling methods both combined with nicotine replacement therapy. Randomization is conducted at the ward level (cross-over). Baseline and follow-up measurements after six and 12 months are obtained. Upon admission to the cardiac ward, nurses assess patients' smoking behaviour, ensure a quit advice and subsequently refer patients for either telephone counselling or face-to-face counselling. The counselling interventions have a comparable structure and content but differ in provider and delivery method, and in duration. Both counselling interventions are compared with a control group receiving no additional treatment beyond the usual care. Between December 2009 and June 2011, 245 cardiac patients who smoked prior to hospitalisation were included in the usual care group, 223 in the telephone counselling group and 157 in the face-to-face counselling group. Patients are predominantly male and have a mean age of 57 years. Acute coronary syndrome is the most frequently reported admission diagnosis. The ultimate goal of the study is to assess the effects of the interventions on smoking abstinence and their cost-effectiveness. Telephone counselling is expected to be more (cost-)effective in highly motivated patients and patients with high SES, whereas face-to-face counselling is expected to be more (cost-)effective in less motivated patients and patients with low SES.

DISCUSSION

This study examines two intensive smoking cessation interventions for cardiac patients using a multi-centre trial with eight cardiac wards. Although not all eligible patients could be included and the distribution of patients is skewed in the different groups, the results will be able to provide valuable insight into effects and costs of counselling interventions varying in delivery mode and intensity, also concerning subgroups.

Risk groups and predictors of short-term abstinence from smoking in patients with coronary heart disease

OBJECTIVES

We sought to identify risk groups among smoking cardiac patients from their social cognitive profiles, and to assess predictors of smoking abstinence shortly after discharge.

METHODS

Smoking cardiac patients (n = 133) completed questionnaires at hospital admission and 1 month after discharge. Hierarchical cluster analysis was used to detect risk groups of smokers, based on baseline scores for smoking-related social cognitions. Regression analyses were used to identify predictors of the intention to abstain from smoking and smoking abstinence 1 month after discharge.

RESULTS

Three groups of smokers were distinguished that differed significantly on the pros of nonsmoking, self-efficacy expectancies toward nonsmoking, social support, social modeling, and smoking behavior. Abstinence from smoking 1 month after discharge was predicted by group membership and a stronger intention to quit. A previous hospital admission because of a cardiac event significantly decreased the likelihood of abstinence.

CONCLUSIONS

One third of cardiac patients are at high risk of continuing smoking after hospital discharge because of an unfavorable smoking and disease history and a poor social cognitive profile. Interventions for cardiac patients should address risk profiles to achieve long-term abstinence. The implications of nursing practices in smoking cessation treatments are discussed.

Women and cardiovascular disease: at a social disadvantage?

BACKGROUND

Cardiovascular disease is the most common cause of death in Australian women. The genesis and progression of cardiovascular disease is modulated by a complex interplay of genetic, physiological, social and economic circumstances. Increasingly the impact of racial, ethic, social and economic inequalities is identified as predictors of cardiovascular disease outcome. Despite important advances over the last 30 years in reducing age adjusted mortality from cardiovascular disease, it continues to represent a major social and economic burden nationally and internationally.

AIM

This paper provides a critical review of the social issues impacting upon women in Australia. It also identifies areas for future interventions with a view to improving outcomes in women with cardiovascular disease.

METHOD

The bibliographic databases; CINAHL, MEDLINE, PsycARTICLES, were searched for relevant studies using the search terms 'women', 'cardiovascular disease', and 'socio-economic status'.

FINDINGS

While some gains have been made in reducing the risk factor profile and rates of death from cardiovascular disease, it is clear that gender, race and socioeconomic disparities persist.

CONCLUSIONS

New approaches are required to improve health differentials for CVD, and reduce the impact of gender, racial, ethic, social and economic factors on health disparities.

The Relationship between Smoking and Depression Post-Acute Coronary Syndrome

The purpose of the current paper is to review research on the relationship between smoking cessation and depressed mood post-Acute Coronary Syndrome (Myocardial infarction or unstable angina; ACS). Emerging evidence regarding the effect of anhedonia-a specific subcomponent of mood disturbance characterized by reduced pleasure-on post-ACS outcomes is also discussed. There is strong evidence that depression prospectively predicts post-ACS relapse to smoking. Weaker evidence suggests that smoking at the time of ACS is related to post-ACS depression. Bupropion is a particularly promising treatment for this population because of its smoking cessation and anti-depressant effects. Future research should focus on the relative risk of using nicotine replacement therapies post-ACS, the efficacy of bupropion for smoking cessation and depression reduction in post-ACS patients, the role of anhedonia in post-ACS smoking cessation, and the development and testing of integrated behavioral treatments (smoking cessation plus interventions targeting mood management) for ACS patients.

Current major depression among smokers using a state quitline

BACKGROUND

Smokers seeking treatment to quit smoking are generally not assessed for current depression, yet depression among smokers may influence quitting outcome.

PURPOSE

This study aims to formally assess current major depression among smokers calling a state tobacco quitline.

METHODS

A total of 844 smokers calling the California Smokers' Helpline in 2007 were screened for depression by the mood module of the Patient Health Questionnaire (PHQ-9). The Social Functioning Questionnaire (SFQ) also was administered to these callers. Two months after the screening, follow-up evaluations were conducted to assess cessation outcome.

RESULTS

In all, 24.2% of smokers met criteria for current major depression and 16.5% reported symptoms indicating mild depression. Callers with current major depression were more likely to be heavy smokers and on Medicaid. Moreover, 74.0% of smokers with current major depression had substantial social and occupational functioning deficits. Two months later, those with major depression at baseline were significantly less likely to have quit smoking (18.5% vs 28.4%).

CONCLUSIONS

Almost one in four smokers who called the California Smokers' Helpline met criteria for current major depression. More than 400,000 smokers call state quitlines in the U.S. for help with quitting each year, which means that as many as 100,000 smokers with serious depressive symptoms are using these services annually. The large number of depressed smokers who seek help suggests a need to develop appropriate interventions to help them quit successfully.

Perceived Risks and Benefits of Quitting Smoking in Non-Treatment Seekers

Little is known about beliefs about quitting and treatment motivation in non-treatment seeking smokers. One hundred eight-eight daily cigarette smokers not currently motivated to quit smoking completed measures of perceived risks and benefits of quitting and motivation to quit. Self esteem related to quitting was positively related to desire to quit, expected success at quitting, confidence in quitting, and motivation to quit. Greater perceived risks of cravings were related to greater expected difficulty of remaining abstinent, and greater perceived risk of increased negative affect was related to decreased expectation of success at quitting, confidence for quitting, and increased expectation for difficulty remaining abstinent. Greater perceived risk of weight gain was related to being less likely to have a goal of complete abstinence. There were no gender, ethnicity, age, or education differences in the relationship of perceived risks and benefits of quitting and motivation. Knowing the risks and benefits that relate to motivation to quit for non-treatment seeking smokers provides the foundation for targeting this group in campaigns to increase quit motivation.

[Acute myocardial infarction in young smokers treated by coronary angioplasty. In-hospital prognosis and long-term outcome in a consecutive series of 93 patients]

AIMS OF THE STUDY

The study evaluated in-hospital and long-term outcome of patients less than 50 years old with myocardial infarction within 12 hours after symptom onset treated by coronary angioplasty.

PATIENTS AND METHOD

This is a retrospective study with survival analysis by Kaplan-Meier method in patients included from December 2003 to February 2008.

RESULTS

We included 93 patients aged 42,8+/-5,2 years old with smoking estimated at 27,7+/-12,7 pack-years. Thirty-one patients (33,3%) were dyslipidemic and 36 patients had family history of coronary artery disease. Thirty patients (32,3%) had an anterior myocardial infarction and four patients (4.4%) had Killip greater than 2. Coronary angioplasty was performed within 4.5+/-3.0 hours after symptom onset with TIMI 3 final flow in the culprit vessel in 96.8%. One patient died from cardiogenic shock. With a follow-up of 85 patients during 20.0+/-15.6 months, the survival without death was 98.2% and survival without major cardiac complication was 87.9% at 24 months. Seventy-two patients (85.7%) were taking a betablocker, 81 patients (96.4%) aspirin, 75 patients (89.3%) a statin and 64 patients (76.2%) an angiotensin-converting inhibitor. Only 50 patients (58.8%) were nonsmokers.

CONCLUSION

Thus, young smokers with acute MI treated by coronary angioplasty have a good prognosis during in-hospital stay and long-term outcome. Secondary medical treatment prevention is well followed but there is a low rate of smoking cessation.

Stopping the cardiovascular disease continuum: Focus on prevention

The cardiovascular disease continuum (CVDC) is a sequence of events, which begins from a host of cardiovascular risk factors that consists of diabetes mellitus, dyslipidemia, hypertension, smoking and visceral obesity. If it is not intervened with early, it inexorably progresses to atherosclerosis, coronary artery disease, myocardial infarction, left ventricular hypertrophy, and left ventricular dilatation, which lead to left ventricular diastolic or systolic dysfunction and eventually end-stage heart failure and death. Treatment intervention at any stage during its course will either arrest or delay its progress. In this editorial, the cardiovascular risk factors that initiate and perpetuate the CVDC are briefly discussed, with an emphasis on their early prevention or aggressive treatment.

Smoking, nicotine and neuropsychiatric disorders

Tobacco smoking is an extremely addictive and harmful form of nicotine (NIC) consumption, but unfortunately also the most prevalent. Although disproportionately high frequencies of smoking and its health consequences among psychiatric patients are widely known, the neurobiological background of this epidemiological association is still obscure. The diverse neuroactive effects of NIC and some other major tobacco smoke constituents in the central nervous system may underlie this association. This present paper summarizes the pharmacology of NIC and its receptors (nAChR) based on a systematic review of the literature. The role of the brain's reward system(s) in NIC addiction and the results of functional and structural neuroimaging studies on smoking-related states and behaviors (i.e. dependence, craving, withdrawal) are also discussed. In addition, the epidemiological, neurobiological, and genetic aspects of smoking in several specific neuropsychiatric disorders are reviewed and the clinical relevance of smoking in these disease states addressed.

The association among depressive symptoms, smoking status and antidepressant use in cardiac outpatients

Both depression and smoking are highly prevalent and related to poorer outcomes in cardiac patients. In this study, the authors examined the association between depressive symptoms and smoking status, described the frequency and type of antidepressant use, and prospectively tested the effects of antidepressant use in smokers on smoking status and psychosocial outcomes. Participants comprised 1,498 coronary artery disease (CAD) outpatients who completed a baseline survey which assessed depressive symptoms, current medications, and smoking status. A second survey was mailed 9 months later that assessed depressive symptoms, anxiety, insomnia and smoking status. Results showed that current and former-smokers had significantly greater depressive symptoms than non-smokers. Ten percent of patients were taking antidepressants, most frequently SSRIs, with significantly more smokers on antidepressants than former and non-smokers. At follow-up, smokers on antidepressants were less likely to have quit, had greater anxiety, depressive symptoms and insomnia than smokers not using antidepressants. This study demonstrated that smokers and quitters with CAD had greater depressive symptoms and use of antidepressants than non-smokers, but that the antidepressants utilized may not be optimizing outcomes.

Long-term prognostic factors of young patients (≤ 35 years) having acute myocardial infarction: the detrimental role of continuation of smoking

Background

There are few and conflicting data regarding the prognostic role of continued smoking in very young survivors of acute myocardial infraction (AMI) after the event.

Design

We conducted a prospective study to evaluate the impact of smoking habits on long-term outcome in individuals who sustained AMI at the age of ≤ 35 years.

Methods

We recruited 147 consecutive patients who had survived their first AMI at the age of ≤ 35 years. Patients were followed up for up to 10 years. Clinical end points were: readmission for acute coronary syndrome, cardiac death or coronary revascularization because of clinical deterioration.

Results

The most prevalent risk factor at presentation was smoking (94.8%). Follow-up data were obtained by 135 patients (32 ± 3 yeas old, 115 men). During follow-up 75 (55.6%) patients reported continuation of smoking. Forty-four (32.6%) patients presented cardiac events (three cardiac deaths, 30 acute coronary syndromes, and 11 revascularizations). Multivariate data analysis showed that persistence of smoking (relative risk = 2.35, 95% confidence interval 1.5–5.25, P = 0.03) and ejection fraction at presentation (relative risk = 0.95, 95% confidence interval 0.91–0.98, P= 0.008) were the only significant predictors of cardiac events after adjusting for various confounding factors. In addition, continuation of smoking was the most significant predictor of cardiac events during follow-up in our sample (i.e. had the lowest log-likelihood ratio as compared with ejection fraction or other covariates).

Conclusion

Persistence of smoking is the most powerful predictor for the recurrence of cardiac events in patients with premature AMI.
