Long-term hospital-based secondary prevention of coronary artery disease: a randomized controlled trial

Smoking cessation and prognosis during long-term follow-up after stroke, TIA, and acute coronary syndrome-results from the randomized controlled NAILED trial

BACKGROUND AND AIMS

About 50% of patients continue to smoke after stroke and myocardial infarction. We aimed to assess the effect of a multiple risk factor intervention on long-term smoking cessation and to explore a possible association between early smoking cessation and long-term prognosis.

MATERIAL AND METHODS

Consecutive patients with stroke/TIA/acute coronary syndrome (ACS) at Östersund Hospital during 2010-2014 were included, randomized to intervention or usual care (1:1), and followed through 2017. This substudy included participants that reported current smoking during hospitalization and were alive at 1 month post discharge when the intervention began (n = 321). The smoking cessation intervention was part of a telephone-based, multiple risk factor intervention delivered by a nurse and consisted of brief advice delivered annually. Smoking cessation at the last follow-up was analyzed as the primary outcome. Smoking cessation at other time points and association between early smoking cessation and prognosis (CV events, survival) were secondary outcomes.

RESULT

After a mean follow-up of 4.2 years, 171 participants reported nonsmoking, with no significant difference between the intervention and control group (50.3% vs. 56.3%, absolute difference 5.9%, 95% CI -5.0 to 16.7, p = 0.286). Of these, 80.7% had stopped smoking within 1 month after discharge. The intervention did not improve smoking cessation proportions in the long or short term, and there was no apparent effect on smoking cessation attempts or sustained abstinence. Smoking cessation within 1 month was associated with lower all-cause mortality (HR 0.52, 95% CI 0.32-0.87), and there was a nonsignificant trend towards a lower incidence of CV events (HR 0.71, 95% CI 0.45-1.12).

CONCLUSION

Annual brief advice by a nurse as part of a multiple risk factor follow-up did not improve long-term smoking cessation after stroke/TIA/ACS. Continued smoking past 1 month was associated with worse prognosis.

Improving transitional care after acute myocardial infarction: A scoping review

Cardiovascular disease remains the leading cause of morbidity and mortality, posing a significant challenge to healthcare systems worldwide. Transitional care interventions, which ensure coordination and continuity of care as patients move between different levels of healthcare, have been shown to reduce unnecessary healthcare utilization and improve patient outcomes. While much attention has been given to transitional care in heart failure, this review aims to map the interventions implemented for patients following an acute myocardial infarction (AMI). A scoping review was conducted following the Joanna Briggs Institute (JBI) methodology, with literature searches performed in the Cochrane, CINAHL, MEDLINE, JBI, and SciELO databases, focusing on publications from 2013 onwards in both Portuguese and English. Seventy-five studies were included, with most combining multiple interventions that contributed to improved cardiovascular health outcomes, including increased adherence to healthy lifestyle behaviors, enhanced medication compliance, and better healthcare self-management. These interventions were effective in reducing cardiovascular-related Emergency Department visits, unplanned 30-day readmissions, and mortality following a first-time myocardial infarction. Key strategies identified included discharge planning, digital health solutions, outpatient care, and healthcare coordination. The findings of this review underscore the need for developing methodologies that enhance the transition of care from hospital to primary care following an AMI. There is an urgent need to design and implement new healthcare programs that integrate discharge interventions, digital health, outpatient care, and healthcare coordination to ensure continuity of care and optimize patient outcomes post-discharge.

Self-reported smoking status and exhaled carbon monoxide in secondary preventive follow-up after coronary heart events: Do our patients tell the truth?

INTRODUCTION

Smoking cessation reduces the risk of myocardial infarctions (MI) and death in patients with coronary heart disease. Smoking status is frequently assessed based on self-report. The aims of this study were to compare self-reported and objectively measured (exhaled carbon monoxide [eCO]) smoking status after MI, percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG), and to assess whether assumed wrongly declared smoking cessation was associated to poorer achievement of other treatment targets for secondary prevention.

METHODS

This study was a sub-analysis from a randomized controlled trial at Sorlandet Hospital, Arendal, Norway, 2007-2022, including patients hospitalized due to MI or after scheduled PCI/CABG, and primarily aimed at comparing secondary preventive follow-up in the outpatient clinic versus primary healthcare. Participants were followed up after the index event through outpatient consultations. Smoking status was assessed by self-report and by eCO (Smokerlyzer, Bedfont, UK) with concentration values ≥6 ppm interpreted as suggesting smoking.

RESULTS

A total of 1540 participants aged 18-80 years were included in the main study. Self-reported smoking status and concomitant eCO measurement one year after the index event were available in 1291 (84%) participants. In all, Brussels, Belgium, from the 12th to the 13th of September 2024. The concentration of eCO was ≥6 ppm one year after the index event in 285 (22%) patients, and 72 (25%) of these patients reported non-smoking. Fewer patients with elevated eCO reporting non-smoking achieved the treatment target for blood pressure (<140/90 mmHg) in comparison to those reporting smoking (53% vs 68%, p=0.02). No differences for the other treatment targets for secondary prevention were found.

CONCLUSIONS

The study indicates a need for objective measures for smoking cessation both in clinical studies and in clinical practice, and may indicate a lack of truthfulness regarding smoking habits.

Implementation of recommendations on the check of risk factors for cardiovascular diseases in patients undergoing coronary re-interventions

METHOD

The study involved 905 patients after coronary interventions, qualified for invasive diagnosis due to symptomatic coronary disease.

AIM

The aim of this study was to check the implementation of recommendations on the control of risk factors for cardiovascular diseases in patients undergoing re-interventions.

RESULTS

Compared to elderly persons, younger people more often increased their physical activity (62 vs. 65 years, p = 0.009), stopped smoking (61 vs. 65 years, p < 0.001) and reduced alcohol consumption (62 vs. 65 years, p = 0.001). People with secondary and higher education increased their physical activity more often than those with primary education (51%, 31% vs. 23%, p = 0.006). Men more often than women decided to limit their alcohol consumption (48% vs. 37%, p = 0.007). Patients with a history of acute coronary syndrome were more likely to quit smoking and reduce their alcohol consumption than those without such a history (47% vs. 37%, p = 0.003 and 42% vs. 34%, p = 0.020, respectively). Only 2% of the subjects achieved the recommended LDL cholesterol values. Forty-eight percent were qualified for reinvasive procedures on the coronary arteries. Less than half of the patients undertook health-promoting behaviors that required modification of existing habits.

CONCLUSION

Age, gender, and education level influence pro-health behaviors. The majority of patients do not achieve the levels of LDL cholesterol and triglycerides consistent with the ESC guidelines in the secondary prevention of coronary disease. Inadequate check of risk factors may result in faster disease progression and coronary re-interventions.

Sex differences in secondary preventive follow-up after coronary heart events

BACKGROUND AND AIMS

Some studies point to sex differences in cardiovascular preventive practices. The aim of this study was to investigate differences in achievement of secondary preventive targets and long-term outcome in men and women after a coronary heart event.

METHODS

This study was a subanalysis from a randomized controlled trial of hospital-based versus primary care-based secondary preventive follow-up at Sorlandet Hospital, Norway, 2007-2022 and included both groups. The main outcome was achievement of treatment targets two years after the index event. Event-free survival was calculated based on the composite of mortality, coronary intervention, stroke, or myocardial infarction during follow-up. Participants were followed-up for up to 10 years after the index event through out-patient consultations.

RESULTS

In total, 337 women and 1203 men were eligible for the study. Due to loss of follow-up during the first two years after the index coronary event 106 (7%) participants were excluded from further analysis (53% withdrawal of consent, 12% death, and 35% other causes) leaving 307 (21%) women and 1127 (79%) men. After two years of follow-up we found no differences between women and men in achievement of blood pressure targets (61% vs. 59%; p = 0.57), LDL-cholesterol goals (64% vs. 69%; p = 0.15), HbA1c-goal in patients with diabetes (49% vs. 45%; p = 0.57), non-smoking (79% vs. 81%; p = 0.34), healthy diets (14% vs. 13%, p = 0.89), physical activity (55% vs. 58%; p = 0.38), use of acetylsalicylic acid (93% vs. 94%; p = 0.39), and use of lipid lowering therapy (92% vs. 94%; p = 0.15). After a median follow-up time of 5.0 [SD 3.2] years there were no differences between women and men regarding composite endpoint (89 [30.0%] vs. 345 [30.6]; p = 0.58), and composite endpoint-free survival did not differ between women and men (hospital-based follow-up HR for women versus men, 0.87, 95% CI 0.62-1.23; p = 0.44 and primary care service HR for women versus men 0.95, 95% CI 0.69-1.31; p = 0.78).

CONCLUSIONS

The study show no sex differences in achievement of secondary preventive targets or composite endpoint after coronary heart events. However, many women and men did not achieve treatment goals, and further improvement in secondary prevention is needed.

Association of Troponin T measurements with long-term outcomes in patients with coronary artery disease participating in a secondary prevention trial

BACKGROUND AND AIMS

Identification of high-risk patients in secondary cardiovascular prevention may be challenging, although risk stratification tools are available. Cardiac troponins might have predictive value in identification of high-risk patients. The aim of this study was to investigate the association between cardiac Troponin T (cTnT) levels following a coronary event and long-term outcomes.

METHODS

This study was carried out as a subanalysis from a randomized controlled trial conducted at Sørlandet Hospital, Norway, where patients hospitalized with myocardial infarction (MI) or scheduled percutaneous coronary intervention (PCI)/coronary artery bypass grafting (CABG) were included between 2007 and 2017. Participants were followed-up for up to 10 years after the index event through out-patient consultations. cTnT was assessed at each consultation as well as information regarding new cardiovascular events or death.

RESULTS

A total of 1278 patients (18-80 years) with complete measurements of cTnT were included. cTnT was elevated (≥ 14 ng/L) one year after the primary event in 241 (19%) of participants. Median follow-up was 5.7 [SD 2.7] years. Cox regression analyses showed reduced survival (adjusted HR 0.37, 95% CI 0.19-0.72; p = 0.003) and composite endpoint-free survival (adjusted HR 0.73, 95% CI 0.55-0.98; p = 0.04) in participants with elevated cTnT versus participants with low cTnT after adjustment for risk factors at inclusion and randomization assignment.

CONCLUSIONS

Assessment of cTnT after coronary heart events may help identify patients at high risk of poor outcomes and might contribute to more focused secondary preventive treatment.

Barriers and facilitators for smoking cessation in chronic smokers with atherosclerotic cardiovascular disease enrolled in a randomized intervention trial: A qualitative study

Objectives

Smoking is common in patients with cardiovascular disease. Despite strong recommendations for cessation and the existence of efficacious pharmacological and behavioral interventions, cessation rates remain low. Therefore, in this study, we explore perceived facilitators and barriers to smoking cessation in patients with atherosclerotic cardiovascular disease who have participated in a cessation intervention study.

Methods

Participants (N = 10) from the intervention arm of a randomized controlled study with access to free cessation support and pharmacological aids completed a semi-structured, in-depth telephone interview after a 6-monthfollow-up between October 2021 and July 2022. The interviews were audio recorded, transcribed, and analyzed according to principles of thematic analysis.

Results

The mean age was 65.7 (range: 55-79) years, and three of the 10 participants were women. Among the participants, five had quit smoking, three had relapsed, and two were persistent smokers. The themes identified encompassed barriers and facilitators to cessation, both including individual and contextual factors. Barriers included the upsides of smoking, difficult life situations, addiction to smoking, smoking in social circles, perceived lack of support and understanding from health professionals. Facilitators included intrinsic motivation, concerns about the health condition, financial implications, specific behavioral strategies, positive influence from the social environment, and helpful components of the cessation intervention.

Conclusion

Smokers with cardiovascular disease who have attended a cessation intervention study report several facilitators weighted against barriers, interacting with the intention to cease smoking. The most important potentially modifiable factors of significance for cessation identified may be addressed through motivational interviews and focus groups with other smokers.

Time trends in incidence, treatment, and outcome in acute myocardial infarction in Norway 2013–19

Aims

Acute myocardial infarction (AMI) is a common cause of morbidity and mortality. The aim of the present study was to assess time trends in the incidence, treatment, and outcome of AMI in a nationwide registry–based cohort of patients.

Methods and results

All patients with a first AMI registered in the Norwegian Myocardial Infarction Registry between 2013 and 2019 were included in this cohort study. The number of patients admitted to Norwegian hospitals with a first AMI decreased from 8933 in 2013 to 8383 in 2019. The proportion of patients with ST-elevation myocardial infarction (STEMI) was stable at 30% throughout the period, and the percentage of STEMI undergoing coronary angiography was stable at 87%. The proportion of patients with non-STEMI undergoing coronary angiography increased by 2.4% per year (95% confidence interval 1.6–3.3) from 58% in 2013 to 68% in 2019. More patients were discharged with secondary preventive medication at the end of study period. Age-adjusted 1-year mortality was reduced from 16.4% in 2013 to 15.1% in 2018. The changes over time were primarily seen in the oldest patient groups.

Conclusion

In the period 2013–19 in Norway, we found a reduction in hospitalizations due to a first AMI. Both the percentage of patients undergoing coronary angiography as well as the percentage discharged with recommended secondary preventive therapy increased during the period, and the age-adjusted 1-year mortality after AMI decreased. A national AMI register provides important information about trends in incidence, treatment, and outcome, and may improve adherence to guideline recommendations.
