Depression and the risk of coronary heart disease: a meta-analysis of prospective cohort studies
BMC Psychiatry volume 14, Article number: 371 (2014)
Several systematic reviews and meta-analyses demonstrated the association between depression and the risk of coronary heart disease (CHD), but the previous reviews had some limitations. Moreover, a number of additional studies have been published since the publication of these reviews. We conducted an updated meta-analysis of prospective studies to assess the association between depression and the risk of CHD.
Relevant prospective studies investigating the association between depression and CHD were retrieved from the PubMed, Embase, Web of Science search (up to April 2014) and from reviewing reference lists of obtained articles. Either a random-effects model or fixed-effects model was used to compute the pooled risk estimates when appropriate.
Thirty prospective cohort studies with 40 independent reports met the inclusion criteria. These groups included 893,850 participants (59,062 CHD cases) during a follow-up duration ranging from 2 to 37 years. The pooled relative risks (RRs) were 1.30 (95% CI, 1.22-1.40) for CHD and 1.30 (95% CI, 1.18-1.44) for myocardial infarction (MI). In the subgroup analysis by follow-up duration, the RR of CHD was 1.36 (95% CI, 1.24-1.49) for less than 15 years follow-up, and 1.09 (95% CI, 0.96-1.23) for equal to or more than 15 years follow-up. Potential publication bias may exist, but correction for this bias using trim-and-fill method did not alter the combined risk estimate substantially.
The results of our meta-analysis suggest that depression is independently associated with a significantly increased risk of CHD and MI, which may have implications for CHD etiological research and psychological medicine.
Cardiovascular disease (CVD) is now a public health crisis in both developed and developing countries. It is the leading cause of mortality and extorts heavy social and economic costs globally ,. Although regular physical activity and maintenance of a healthy diet (and health weight) are probably the most crucial ways to prevent the disease -, mental health status may provide an additional preventive strategy against CHD risk.
Depression is a common mental disorder, which usually causes severe disability and imposes a huge burden of disease on individuals, families and societies . It is estimated that 5.8% of men and 9.5% of women will experience a depressive episode in any given year . Depression is highly prevalent in the world. The average lifetime prevalence of depression has been estimated at 14.6% in high-income countries, 11.1% in low-to middle-income countries . According to the estimate by World Health Organization (WHO), depression will become the second leading cause of disability-adjusted life years lost by the year 2020 . During the past decades, a large body of epidemiological studies suggested that depression was associated with an increased risk of chronic diseases , including CHD.
Previous reviews - showed that depression has been associated with CHD, but they had some limitations. In 1987, the first meta-analysis  showed that depression was an risk factor for CHD, but most of the studies included in that review were cross-sectional in design , which maybe have more confounding bias. As we know, the prospective cohort study owned the strongest evidence in observational studies. Prospective data to exclude some possible sources of bias that may exist in retrospective data could do good to come to more definitive conclusions. Rugulies  showed that depression was a predictor for coronary heart disease based on cohort studies, while the review did not fully investigate other subgroups except for the type of depression measurement. Other two meta-analyses ,were published on this topic in the past 10 years and the most recent one was published in 2007. The meta-analysis  in 2007 reported a pooled relative risk estimated of 1.48 (95% CI, 1.29–1.69) for CHD, which focused on the cardiovascular outcomes and took pooled effect size of CHD from 16 studies published before 2005 as a secondary analysis. Furthermore, the review did not exclude those studies that participants were with CHD at the study baseline, which did not clearly enable reader to discern the depression as pre-morbid risk factor, and affected the magnitude of the true association. Potential publication bias was also not fully explored in this review. Since the publication of the last review on this topic, many more prospective studies have emerged, which allowed to perform more detailed analysis for new insights and obtain more powerful evidence on the association between depression and CHD risk. Given the limitations of previous reviews and the higher level of evidence from prospective cohort studies, along with the additional recent studies, it was necessary for us to assess the association between depression and the risk of CHD by conducting an updated meta-analysis based on prospective cohort studies.
We performed this systematic review in accordance with the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines . A literature search of PubMed, Embase and Web of Science from their inception to April 2014 for prospective cohort studies describing the association between depression status (defined by self-reported scales, clinician/physician diagnosis, or structured clinical diagnostic interview) and the risk of CHD was conducted. We used the following search terms “depression,” “depressive symptoms,” “depression disorder,” and “coronary heart disease” or “ischemic heart disease” or “myocardial infarction” [MeSH] or “cardiovascular diseases” [MeSH] combined with “cohort studies” “follow-up studies” “prospective studies” “longitudinal studies”. In addition, the reference lists of all identified relevant publications and relevant reviews were reviewed. Only articles published in English were considered.
Studies were included in the meta-analysis if they met the following criteria: (1) the study was a population-based or community-based prospective cohort study design; (2) the exposure of interest was depression symptoms; (3) the outcome of interest was CHD or MI; (4) participants were free of CHD at study entry; (5) the study reported the risk estimates with 95% confidence interval (CI) for the association between depression and CHD. Studies were excluded if (1) the study had a retrospective design; (2) the estimates were presented without standard errors or other information that allowed calculation of standard errors; (3) no confounders were adjusted for. In the case of multiple publications from the same study, only the most recent paper or article with a longer follow-up was included.
We extracted the following information from each retrieved study: name of the first author, year of publication, study location, characteristics of study population at baseline, duration of follow-up, definition and measurement of exposure, outcomes, number of cases, size of cohort, adjusted relative risk (RR) with 95% CI, and covariates that were adjusted in the multivariable analysis. Data extraction was conducted independently by two authors (Y.G. and Y.H.G). Interobserver agreement was assessed using Cohen kappa (κ), and any differences were resolved by discussion with the third author (Z.X.L.).
To determine the validity of included studies, two reviewers (Y.G. and Y.H.G.) independently performed the quality assessment by using the Newcastle-Ottawa Scale , which is a validated scale for non-randomized studies in meta-analyses . The Newcastle-Ottawa Scale is a nine-point scale that allocates points based on the selection process of cohorts (0–4 points), the comparability of cohorts (0–2 points), and the identification of the exposure and the outcomes of study participants (0–3 points). We assigned scores of 0–3, 4–6, and 7–9 for low, moderate, and high quality of studies, respectively. Each study was rated independently by two authors (Y.G. and Y.H.G.); ratings were reported in Additional file 1: Table S1.
In this meta-analysis, the RR was used as a common measure of the association between depression and the risk of CHD, and the hazard ratios (HRs) was considered equivalent to RRs. If articles provided RRs for women and men separately, we pooled both risk estimates to obtain one overall estimates for the primary analysis. If studies reported fatal or nonfatal outcomes, the two outcomes were considered as two independent reports respectively for all analysis. To be consistent across studies, we used binary variables (yes/no) for depression and CHD. We did not include studies using depressive scale as a continuous variable because the risk estimates were not comparable with those using categorized depression measures.
The heterogeneity among studies was estimated by the Cochran Q test and I 2 statistic. P < 0.10 was considered indicative of statistically significant heterogeneity. Statistical heterogeneity among studies was evaluated using the I 2 statistic, where values of 25%, 50% and 75% represent cut-off points for low, moderate and high degrees of heterogeneity, respectively . When appropriate, we used a fixed-effects model or random-effects model. The RRs were pooled using the fixed-effects model if no heterogeneity was detected, or the random-effects model was used otherwise .
We conducted stratified analyses and sensitive analyses to evaluate the influences of study and population characteristic on study results. We used the Begg test , the Egger test  and visual inspection of a funnel plot to assess the publication bias. The Duval and Tweedie nonparametric trim-and-fill method  was performed to further assess the potential publication bias. All analyses were performed with STATA statistical software version 11.0 (STATA Corp, College Station, TX, USA). All tests were two sided with a significance level of 0.05.
Literature search and study selection
Initially, 9022 articles from the PubMed, Embase, and Web of Science were identified. The majority were excluded after the first screening of titles or abstracts, because they were duplicates, reviews, case–control studies, cross-sectional studies, or not relevant to our analysis. After assessing full texts for detailed evaluation, 30 studies - met the inclusion criteria and were included in the meta-analysis. A flow chart showing the study selection was presented in Figure 1. Interobserver agreement (κ) was 0.959, which indicated a very outstanding concordance between raters for article inclusion decisions . The quality of studies was generally good, with results of study quality assessment yielded a score of 6 or above for all included studies, with an average score of 7.8.
Additional file 1: Table S1 showed the main characteristics of 30 prospective cohort studies included that were published between 1993 and 2014. With regard to study location, fifteen studies were conducted in the United States, twelve in European countries (one of the twelve studies was a multi-country study), one each in Hong Kong, Taiwan, and Canada. The study samples ranged from 660 to 345,949, with a total of 893,850, and the follow-up durations ranged from 2 to 37 years. The number of CHD cases diagnosed in the primary studies ranged from 45 to 11,659, with 59,062 reported CHD outcomes (two studies , did not report the number of CHD cases). Twenty-three studies reported results for both men and women, six reported results for men and women separately (The result of one study is only available for men ), five studies reported results for men only, and two studies reported results for women only. One study  reported results by time interval: 0 to 5 year and 5 to 10 year. Three studies ,, reported the outcome of fatal and nonfatal CHD simultaneously. The assessment of depression varied across studies, twenty-two studies administered a validated questionnaire of depression symptoms, in which nine different self-reported symptom scales were represented in Additional file 1: Table S1. Twelve of twenty-two studies used the Center for Epidemiology Studies Depression scale (CESD). Of the 30 studies, 24 reported CHD outcomes and 12 reported MI outcomes. The proportion of major depression or scoring above the cutoff of self-rating instruments ranged from 1.3 to 50.6% (average 17.5%). The prevalence rate of depression symptoms was much higher than clinical diagnosis. Outcome ascertainment was from a variety of sources, such as medical records, self-report, register database, National Death Index, clinical diagnoses, and death certificates. The major adjustment confounding factors included age, sex, smoking, alcohol intake, physical activity, body mass index (BMI), diabetes, hypertension and cholesterol.
Association between depression and the risk of all CHD events
Thirty studies with 39 reports were included in the analysis of depression and CHD risk. The results from random-effects meta-analysis of depression and the risk of CHD were shown in Figure 2. Of the 39 reports, 21 showed a significantly positive relationship between depression and the risk of CHD, while the other reports did not. The pooled RR of CHD for depression was 1.30 (95%CI, 1.22–1.40). Substantial heterogeneity was observed (P < 0.001; I 2 = 71.9%).
Association of depression with the risk of MI
The results from random-effects meta-analysis of depression and the risk of MI were shown in Figure 3. Of the 12 studies, 8 showed a significant positive association between depression and MI risk, and 4 suggested no statistically significant association of interest. The pooled RR was 1.30 (95% CI, 1.18–1.44), and there was a moderate to high heterogeneity (P = 0.001; I 2 = 64%). Visual inspection of the Begg funnel plot did not identify substantial asymmetry. Neither the Begg test nor the Egger test for publication bias reached significance (P > 0.05 for both tests).
Of note, one study  was excluded because depressive symptoms score was used as a continuous variable. We added the RR from the study to the main analysis of MI, and the pooled RR was 1.26 (95 CI%, 1.16 to 1.37). Thus, our results would not change even if the study was included.
Table 1, Additional file 1: Table S2 and S3 showed the results from subgroup analyses examining the stability of the primary results and exploring the resource of heterogeneity. The associations between depression and the risk of CHD and MI were similar in most subgroup analyses, which were stratified by sex, mean age at baseline, publication year (before 2005 vs. after 2005), duration of follow-up, study location, type of depression measure, and whether smoking, BMI, diabetes, hypertension, physical activity, cholesterol or socioeconomic status were controlled or not in models. However, moderate to high heterogeneities were observed in most subgroups. The increased CHD risk was more evident in the groups of less than 15 years follow-up and adjusted for hypertension. No significant between-group difference was found for other variable (see Additional file 1: Table S2 and S3).
Sensitivity analyses were performed to detect potential sources of heterogeneity in the association between depression and the risk of CHD, and to examine the influence of various exclusion criteria on the combined risk estimate. Exclusion of 3 studies that their outcomes were CHD plus MI showed a greater risk 1.35 (95% CI, 1.22–1.50), and statistical heterogeneity was forcefully attenuated (P =0.001, I 2 = 52.8%). Exclusion of the study by Cohen et al. that enrolled patients with hypertension yielded a pooled RR of 1.29 (95%CI, 1.17-1.43; P < 0.001). We excluded any single study in turn and pooled the results of the remaining studies. The overall combined RR did not change substantially, with a range from 1.29 (95% CI, 1.17 to 1.42; P <0.001) to 1.34 (95%CI, 1.21 to 1.48; P <0.001).
Two studies , were excluded because depressive symptoms score was used as a continuous variable rather than a binary variable. We added the RRs from the two studies to the main analysis of CHD, and the results did not change substantially (RR, 1.25; 95% CI, 1.16 to 1.34).
Visual inspection of the Begg funnel plot did not reveal any asymmetry. The Begg test was not significant (z = 1.13; P = 0.26), which identified no evidence of substantial publication bias, but the Egger test did not (P = 0.059). A sensitivity analysis using the trim-and-fill method was performed with 5 imputed studies, which produced a symmetrical funnel plot (see Figure. 4). The corrected RR using the trim-and-fill method was 1.25 (95% CI, 1.14–1.38; P < 0.001). Correction for potential publication bias therefore did not alter the combined risk estimate substantially.
The results of our meta-analysis of 30 prospective cohort studies with 40 independent reports suggest that depression is associated with a significantly increased risk of CHD and MI. Participants with depression, compared with those free of it, experienced a significant increased risk of 30% for CHD and MI. Furthermore, the association remained significant in the groups adjusted for potential confounders, such as lifestyle factors and socio-demographic factors.
Comparison with previous studies
The present meta-analysis showed that the pooled adjusted RRs were 1.30 (95% CI, 1.22–1.40), 1.30 (95% CI, 1.18–1.44) for CHD and MI, respectively, which were much lower than those from a previous meta-analysis published 2007 for CHD (RR, 1.48; 95% CI, 1.29–1.69) and for MI (RR, 1.60; 95% CI, 1.34–1.92). Our meta-analysis included 19 new prospective cohort studies with larger sample size and many more cases, which significantly enhanced statistical power to detect the potential associations of depression with CHD and MI. In addition, we also fully explored the potential publication bias. Although potential publication bias may exist, correction for this bias using trim-and-fill method remained statistically significant. More important, compared with the previous meta-analysis in 2007, the associations differed between populations of different ethnic backgrounds was investigated. We found that the association trended to be stronger for participants from the United States than for European participants. There was null statistically significant risk of CHD in Hong Kong, which might result from the limited number of included studies (One study with two reports comprising 62,839 participants). Given that the studies included in our meta-analysis were conducted in affluent countries (areas) in North America, Western Europe, and Hong Kong, the results should not be extended to developing countries. In order to make the finding generalize to other populations, more studies conducted in other populations from Asia, Africa and South America are warranted.
Our subgroups analyses identified two important and valuable findings. A major finding was that depression increased the risk of CHD in the group of less than 15 years follow-up, but did not have statistically significant association for equal to or more than 15 years follow-up, which was a very interesting phenomenon. One possible explanation to this finding was that most studies have usually measured depression only one time at the beginning of the study, and have assessed the outcomes at the end of the follow-up. It was well known that depression was treatable and depressive individuals could recover during the follow-up. The longer the follow-up duration, the more people could recover, which might weaken the association between depression and CHD risk. In turn, the finding confirmed that the depression was associated with CHD risk.
Another finding was that depression could be an independent risk factor for CHD. In our subgroup analyses, studies adjusted for smoking, BMI, hypertension, diabetes, physical activity, and socioeconomic status did not influence the result of positive association, which suggested that adequate adjustment was not definite to weaken the pooled effect estimate and conclusion .
In the subgroup analysis type of depression measurement, it was notable that the association was much stronger in these studies that identified depression using self-reported scales rather than structured clinical diagnostic interviews or clinical diagnosis. One possible interpretation was that the estimates of depression may differ depending on the use of dimensionally versus categorically based depression assessment tools . Structured psychiatric interviews would definitely exclude individuals with subsyndromal depressive symptoms from case status. Conversely, utilization of self-reported symptom scales would allow the inclusion of a lot of people with clinically significant depressive symptoms who failed to meet formal criteria for diagnostic and statistical manual of mental disorders (DSM) diagnosis, but a large body of evidence showed that subsyndromal depressive symptoms, like clinical syndromes, were significantly associated with adverse functional outcomes, disability, morbidity and mortality . Therefore, inclusion of people with subsyndromal depression in the reference category may weaken the risk estimates of studies with categorically based depression definition. More important, there were quite clear differences present that go opposite to a dose–response association between depression and CHD. The interesting finding deserves attention from related researchers. More studies investigating the association between depression and CHD risk based on the use frequency of self-report instruments and interviews over time are needed, which will help to explore the dose–response relationship with them. Specially, in our meta-analysis, a majority of studies defined depression status by self-reported symptom scales, thus our findings much more trended to generalize to the populations who had depression symptoms.
On the basis of our research findings, it was expected that treatment with antidepressants would reduce the risk of development of CHD. Conversely, some observational studies , suggested treatment with antidepressants was associated with increasing risk of CHD. However, the results should be interpreted cautiously because medication use could be a marker of depression severity , evidence from a meta-analysis of clinical trials showed that treatment with antidepressants was beneficial for CHD . Thus, patients with antidepressants medication use were more likely to have severe depressive symptoms, and the increased risk of CHD may be attributable to depression severity rather than the antidepressant medication use.
Interestingly, although the evidence from observational studies on the association between depression and the risk of CHD seemed to be robust, the evidence from randomized controlled trials (RCTs) did not find an effect of the intervention ,. We noted that evidence from RCTs had suggested that the treatment response and medical prognosis of different patient subgroups appear different . For example, among post–acute coronary syndrome patients, depression, particularly if mild, might be monitored for remission without treatment. On the contrary, persistent depression, particularly if treatment recalcitrant, should be treated, taking into considering the link to adverse post-acute coronary syndrome outcomes . In addition, studies suggested that gender might play a different role in affecting the medical outcomes from psychotherapy ,. Therefore, more research is needed to further investigate the prognosis of subgroups based on depression severity and/or onset and gender, which would help to reveal the relationship between depression and CHD.
Study strengths and limitations
Our review is very valuable and crucial though it is an updated meta-analysis. Firstly, we not only included the prospective cohort studies, also included 19 more new studies and 759,922 more new participants than the previous reviews, which provided stronger and more sufficient evidence. Secondly, on the basis of our subgroup analysis, an important methodological finding was worth paying attention to. In cohort studies with longer follow-up, exposure (such as depression) might be mutative, but the exposure measurement frequency was often inadequate, which should arouse the investigator’s attention in the population-based observational epidemiological studies.
A few limitations of our meta-analysis should be acknowledged. Firstly, we observed robust and consistent associations across different subgroups via sensitivity analyses and subgroup analyses. Yet as a limitation, there was the evidence of heterogeneity across the studies used for the analysis of association between depression and the risk of CHD. The heterogeneity might result from the difference of participants’ characteristic, sample sizes, study designs, and diagnostic criteria of depression. Thus, the results of this meta-analysis should be interpreted cautiously. Secondly, the measurement of depression mostly used the self-reported symptom scales, which could cause the misclassification of exposure , and might underestimate the reported association. Thirdly, the publication bias were observed, however, we used trim-and-fill method to correct the bias, which did not obviously alter the positive association. Fourthly, the receipt and type of depression treatment were not taken into consideration, and many studies lacked information on depression treatment and antidepressant medication use. The role of depression treatment in modulating subsequent risk of CHD needs to be studied further.
Suggestions for further studies
On the basis of our findings, we put forward some suggestions for future studies. Firstly, more studies are needed to assess depression in a repeated-measures design with diagnostic interview as well as self-report during the follow-up. Secondly, in order to achieve stronger research evidence, investigators should strive to improve the standardization of their depression measurement and outcome definitions . Thirdly, we should inquire the variation of depression of participants at the end of the follow-up, and further accurately assess the association between depression and the risk of CHD. Finally, more interventional studies are needed to explore the underlying mechanisms and to determine the cause and effect relationships that link depression and CHD.
In conclusion, our meta-analysis of prospective studies suggests that depression is probably an independent risk factor, which is associated with a 30% increase risk for CHD and MI. Given the high prevalence of depression in the general population and the heavy economic burden of CHD, it is greatly important for us to take depression account into the clinical prevention and treatment of CHD.
