Association between depressive symptoms and atherosclerotic cardiovascular disease: a Swedish population-based cohort study.
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAtherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality globally. While traditional risk factors such as hypertension, smoking, and dyslipidemia are well established, the role of depressive symptoms in ASCVD development, particularly in premature cases, is less understood. This study aims to determine the association between depressive symptoms, including severity and anxious distress as specifiers, with ASCVD and premature ASCVD in a Swedish population-based cohort.
methodsWe utilized data from the PART study (acronym in Swedish for: Psykisk hälsa, Arbete och RelaTioner: Mental Health, Work and Relationships), a longitudinal cohort study which include a total of 11,175 adults in Stockholm, Sweden. Depressive symptoms were assessed using the Major Depression Inventory across three waves from 1998 to 2010 Incident ASCVD cases were identified through the National Patient Register (NPR) until 2021. Premature ASCVD was defined as occurring before age 55 in men and 65 in women. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs), adjusting for sociodemographic factors, lifestyle behaviors, and cardiometabolic conditions.
resultsParticipants with depressive symptoms had a 42% increased risk of ASCVD (HR 1.42, 95% CI 1.19-1.68), independent of traditional cardiovascular risk factors. When stratifying by ASCVD type, depressive symptoms were associated with ischemic heart disease (HR 1.39, CI 1.06-1.83) and stroke (HR 1.53, CI 1.15-2.05). The risk varied by severity, with mild depressive symptoms associated with ischemic heart disease (HR 1.62, CI 1.11-2.37) and moderate (HR 1.70, 95% CI 1.04-2.78) and severe depressive symptoms (HR 1.61, 95% CI 1.04-2.49) were associated with stroke. Furthermore, participants with combined depressive symptoms and anxious distress had an increased risk of stroke (HR 1.50, CI 1.09-2.07), whereas participants with depressive symptoms without anxious distress had an increased risk of ischemic heart disease (HR 1.88, CI 1.25-2.82). The risk of premature ASCVD was increased among individuals with depressive symptoms (HR = 1.52, 95% CI 1.12-2.05). When examined by level of severity, only among subjects with mild depressive symptoms, a statistically significant association with premature ASCVD (HR = 1.61, 95% CI 1.05-2.48) was found.
conclusionsThis study provides evidence linking depressive symptoms to ASCVD and premature ASCVD in a Swedish population. The findings underscore the need to consider the effects of depressive symptoms as well as potential prevention strategies for depressive symptoms in regard to cardiovascular diseases. Future research should explore whether early identification and treatment of depressive symptoms can mitigate ASCVD risk and improve long-term cardiovascular outcomes.
