Risk of depression after coronary artery bypass grafting: a SWEDEHEART population-based cohort study.

ABSTRACT:

Aims

A diagnosis of depression in patients with coronary heart disease is associated with worse outcomes. This study examined the long-term risk for new onset of depression after coronary artery bypass grafting (CABG) compared to an age- and sex-matched control group from the general population.

Methods and results

In total, 125 418 primary isolated CABG patients and 495 371 matched controls were included from 1992 to 2017. The SWEDEHEART registry and three other national registers were used to acquire information about baseline characteristics and depression. The adjusted risk of depression was estimated by using Cox regression models adjusted for patient characteristics, and socioeconomic variables, described by hazard ratios (HR) and 95% confidence intervals (CI). In total, 6202 (4.9%) CABG patients and 17 854 (3.6%) controls developed depression. The cumulative incidence of depression was higher in CABG patients than in the control population [6.1%, 95% CI 6.0-6.3 vs. 4.7% (4.7-4.8), P < 0.0001]. Overall, the CABG group had a marginally increased adjusted risk of depression compared to controls [adjusted HR (aHR): 1.05 (1.01-1.09), P = 0.0091]. In age-specific analyses, the increased risk compared to controls was only present in patients <65 years [aHR: 1.19 (1.11-1.27), P <0.0001] and was only evident during the first 5 years after surgery.

Conclusion

Patients who underwent CABG had a higher risk of new onset of depression compared to sex- and age-matched controls in the general population. The risk of depression was especially pronounced in younger patients during the first 5 years after surgery.

Project description:Background Low income and short education have been found to be independently associated with inferior survival after coronary artery bypass grafting (CABG), whereas the use of secondary prevention medications is associated with improved survival. We investigated whether underusage of secondary prevention medications contributes to the inferior long-term survival in CABG patients with a low income and short education. Methods and Results Patients who underwent CABG in Sweden between 2006 to 2015 and survived at least 6 months after discharge (n=28 448) were included in a population-based cohort study. Individual patient data from 5 national registries, including the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) registry, covering dispensing of secondary prevention medications (statins, platelet inhibitors, β-blockers, and RAAS inhibitors), socioeconomic factors, patient characteristics, comorbidity, and long-term mortaity were merged. All-cause mortality risk was estimated using multivariable Cox regression models adjusted for patient characteristics, baseline comorbidities, time-updated secondary prevention medications, and socioeconomic status. Long-term mortality was higher in patients with a low income and short education. Statins and platelet inhibitors were dispensed less often to patients with a low income, both at baseline and after 8 years. The decline in dispensing over time was steeper for low-income patients. Short education was not associated with reduced dispensing of any secondary prevention medication. Use of statins (adjusted hazard ratio=0.57 [95% CI, 0.53-0.61]), RAAS inhibitors (adjusted hazard ratio=0.78 [0.73-0.84]), and platelet inhibitors (adjusted hazard ratio=0.74 [0.68-0.80]) were associated with reduced long-term mortality irrespective of socioeconomic status. Conclusions Secondary prevention medications are dispensed less often after CABG to patients with low income. Underusage of secondary prevention medications after CABG is associated with increased mortality risk independently of income and extent of education.

Project description:Background The long-term impact of new-onset postoperative atrial fibrillation (POAF) after coronary artery bypass grafting and the benefit of early-initiated oral anticoagulation (OAC) in patients with POAF are uncertain. Methods and Results All patients who underwent coronary artery bypass grafting without preoperative atrial fibrillation in Sweden from 2007 to 2015 were included in a population-based study using data from 4 national registries: SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-based Care in Heart Disease Evaluated According to Recommended Therapies), National Patient Registry, Dispensed Drug Registry, and Cause of Death Registry. POAF was defined as any new-onset atrial fibrillation during the first 30 postoperative days. Cox regression models (adjusted for age, sex, comorbidity, and medication) were used to assess long-term outcome in patients with and without POAF, and potential associations between early-initiated OAC and outcome. In a cohort of 24 523 patients with coronary artery bypass grafting, POAF occurred in 7368 patients (30.0%), and 1770 (24.0%) of them were prescribed OAC within 30 days after surgery. During follow-up (median 4.5 years, range 0‒9 years), POAF was associated with increased risk of ischemic stroke (adjusted hazard ratio [aHR] 1.18 [95% CI, 1.05‒1.32]), any thromboembolism (ischemic stroke, transient ischemic attack, or peripheral arterial embolism) (aHR 1.16, 1.05‒1.28), heart failure hospitalization (aHR 1.35, 1.21‒1.51), and recurrent atrial fibrillation (aHR 4.16, 3.76‒4.60), but not with all-cause mortality (aHR 1.08, 0.98‒1.18). Early initiation of OAC was not associated with reduced risk of ischemic stroke or any thromboembolism but with increased risk for major bleeding (aHR 1.40, 1.08‒1.82). Conclusions POAF after coronary artery bypass grafting is associated with negative prognostic impact. The role of early OAC therapy remains unclear. Studies aiming at reducing the occurrence of POAF and its consequences are warranted.

Project description:BackgroundPostoperative delirium (POD) is a common complication of major surgery and is associated with fortified morbidity, mortality, and long-term cognitive dysfunction. This study sought to evaluate the incidence and risk factors of delirium in elderly (aged ≥65 years) patients who underwent coronary artery bypass grafting (CABG).MethodsWe performed a retrospective cohort analysis. The clinical data of 1,426 elderly patients who underwent CABG at our hospital from October 2018 to October 2020 were collected and analyzed. Delirium was defined as any positive Confusion Assessment Method for Intensive Care Unit examination following surgery during the intensive care unit (ICU) stay. Risk factors for POD were authenticated via univariate and multivariate logistic regression analyses. The intraoperative and postoperative factors were evaluated using a propensity score-matched regression analysis based on preoperative factors.ResultsA total of 39.3% (560 of 1,426) of elderly patients who underwent CABG were diagnosed with delirium. Based on the multivariate analysis, age [odds ratio (OR) 1.013], long-term alcohol consumption (OR 2.026), diabetes (OR 1.51), stroke (OR 1.41), and extracardiac arteriopathy (OR 1.61) were found to be independent predictors of post-cardiac surgery delirium. Conversely, high-density lipoprotein cholesterol levels (HDL-C) ≥1.0 mmol/L (OR 0.71) was found to be a protective factor. Among the intraoperative and postoperative factors evaluated, only a prolonged ICU stay (≥48 h; OR 1.62) was identified as a risk factor for developing delirium in the propensity-score matched analysis, after adjusting for potential confounding variables and selection bias. In contrast to the earlier analysis, the multivariate logistic regression further revealed that peri-procedural myocardial infarction and postoperative arterial oxygen partial pressures were not significantly associated with POD.ConclusionsThe incidence of POD in elderly patients undergoing CABG was high. Factors such as older age, long-term alcohol consumption, diabetes, stroke, and extracardiac arteriopathy were independent risk factors for POD in these patients. In relation to the intraoperative and postoperative factors, after adjusting for preoperative confounding factors, only a prolonged ICU stay was identified as a risk factor for POD. Additionally, high levels of HDL-C may be beneficial in reducing the incidence of delirium.
