Mental health status and risk of new cardiovascular events or death in patients with myocardial infarction: a population-based cohort study.

ABSTRACT: To examine the association between mental health status after first-time myocardial infarction (MI) and new cardiovascular events or death, taking into account depression and anxiety as well as clinical, sociodemographic and behavioural risk factors.Population-based cohort study based on questionnaires and nationwide registries. Mental health status was assessed 3 months after MI using the Mental Component Summary score from the Short-Form 12 V.2.Central Denmark Region.All patients hospitalised with first-time MI from 1 January 2009 through 31 December 2009 (n=880). The participants were categorised in quartiles according to the level of mental health status (first quartile=lowest mental health status).Composite endpoint of new cardiovascular events (MI, heart failure, stroke/transient ischaemic attack) and all-cause mortality.During 1940 person-years of follow-up, 277 persons experienced a new cardiovascular event or died. The cumulative incidence following 3 years after MI increased consistently with decreasing mental health status and was 15% (95% CI 10.8% to 20.5%) for persons in the fourth quartile, 29.1% (23.5% to 35.6%) in the third quartile, 37.0% (30.9% to 43.9%) in the second quartile, and 47.5% (40.9% to 54.5%) in the first quartile. The HRs were high, even after adjustments for age, sociodemographic characteristics, cardiac disease severity, comorbidity, secondary prophylactic medication, smoking status, physical activity, depression and anxiety (HR3rd quartile 1.90 (95% CI 1.23 to 2.93), HR2nd quartile 2.14 (1.37 to 3.33), HR1st quartile 2.23 (1.35 to 3.68) when using the fourth quartile as reference).Low mental health status following first-time MI was independently associated with an increased risk of new cardiovascular events or death. Further research is needed to disentangle the pathways that link mental health status following MI to prognosis and to identify interventions that can improve mental health status and prognosis.

Project description:BACKGROUND:Depressive symptoms is associated with adverse cardiovascular outcomes in patients with myocardial infarction (MI), but the underlying mechanisms are unclear and it remains unknown whether subgroups of patients are at a particularly high relative risk of adverse outcomes. We examined the risk of new cardiovascular events and/or death in patients with depressive symptoms following first-time MI taking into account other secondary preventive factors. We further explored whether we could identify subgroups of patients with a particularly high relative risk of adverse outcomes. METHODS AND RESULTS:We conducted a prospective population-based cohort study of 897 patients discharged with first-time MI between 1 January 2009 and 31 December 2009, and followed up until 31 July 2012. Depressive symptoms were found in 18.6% using the Hospital Anxiety and Depression Scale (HADS-D?8). A total of 239 new cardiovascular events, 95 deaths, and 288 composite events (239 new cardiovascular events and 49 deaths) occurred during 1,975 person-years of follow-up. Event-free survival was evaluated using Cox regression analysis. Compared to the 730 patients without depressive symptoms (HADS-D<8), the 167 patients with depressive symptoms (HADS-D?8) had age- and sex-adjusted hazard ratios [HR] (95% confidence interval [CI]) of 1.53 (95% CI, 1.14-2.05) for a new cardiovascular event, 3.10 (95% CI, 2.04-4.71) for death and 1.77 (95% CI, 1.36-2.31) for a composite event. The associations were attenuated when adjusted for disease severity, comorbid conditions and physical inactivity; HR?=?1.17 (95% CI, 0.85-1.61) for a new cardiovascular event, HR?=?2.01 (95% CI, 1.28-3.16) for death, and HR?=?1.33 (95% CI, 1.00-1.76) for a composite event. No subgroups of patients had a particularly high risk of adverse outcomes. CONCLUSIONS:Depressive symptoms following first-time MI was an independent prognostic risk factor for death, but not for new cardiovascular events. We found no subgroups of patients with a particularly high relative risk of adverse outcomes.

Project description:ObjectiveTo examine the long-term use of healthcare contacts to general practice (GP) and hospital after a first-time myocardial infarction (MI) according to mental health and socioeconomic position.MethodsPopulation-based cohort study of all patients discharged with first-time MI in the Central Denmark Region in 2009 (n=908) using questionnaires and nationwide registers. We estimated adjusted incidence rates and incidence rate ratios (IRR) for GP and hospital contacts according to depressive and anxiety symptoms, educational level and cohabitation status.ResultsDuring the 24-month period after the MI, patients with anxiety symptoms had 24% more GP contacts (adjusted IRR 1.24, 95% confidence interval (CI) 1.12-1.36) than patients with no anxiety symptoms. In contrast, patients with depressive symptoms (1.05, 0.94-1.16) and with short and medium education (<10 years: 0.96, 0.84-1.08; 10-12 years: 0.91, 0.80-1.03) and patients living alone (0.95, 0.87-1.04) had the same number of GP contacts as their counterparts (patients with no depressive symptoms, with long education [>12 years] and patients living with a partner). During the first 6 months after the MI, patients living alone had 13% fewer hospital contacts (0.87, 0.77-0.99), patients with short education had 16% fewer hospital contacts (<10 years: 0.84, 0.72-0.98) and patients with anxiety symptoms had 27% fewer hospital contacts (0.73, 0.62-0.86) than their counterparts. In contrast, patients with depressive symptoms (0.92, 0.77-1.10) and medium education (10-12 years: 1.05, 0.91-1.22) had the same number of hospital contacts as their counterparts.ConclusionsThis study indicates that patients with depressive symptoms, short and medium education and patients living alone have a lower long-term use of healthcare contacts following MI than patients without these risk factors. Patients with depressive symptoms and low socioeconomic position would be expected to have a higher need of healthcare after MI as they have a poorer prognosis.

Project description:Diet has been associated with better mental health in general populations, but less is known on this association in patients with a history of coronary heart disease. The objective of this study is to examine the cross-sectional associations between dietary patterns and mental health in elderly patients with a history of myocardial infarction.Data were drawn from the final assessment of the Alpha Omega cohort that monitored patients with a history of myocardial infarction (age range 60-80 years). 2171 patients with complete data for diet and mental health were included in this study. Diet was assessed with the 203-item Food Frequency Questionnaire, and subsequently categorized into two scores: the Dutch Healthy Nutrient and Food Score (DHNaFS) and the Dutch Undesirable Nutrient and Food Score (DUNaFS). Depressive symptoms, assessed with the Geriatric Depression Scale (GDS-15), and dispositional optimism, assessed with the 4-item questionnaire (4Q), were cross-sectionally analyzed in relation to dietary patterns using linear regression analysis.Patients were on average 72.2 years old and 79.5% were male. The DHNaFS score was associated with less depressive symptoms and higher dispositional optimism (? = -0.108; P<0.001; and ? = 0.074; P<0.001), whereas no associations were found with the DUNaFS score. Particularly, consumption of vegetables, fruits, whole grains, fish, and low fat-dairy were associated with less depressive symptoms and higher optimism. Similar associations were found when analyzing the association between average DHNaFS score over the preceding 41 months with depression ? = -0.085; P<0.001) and higher dispositional optimism (? = 0.084; P<0.001).A healthy dietary pattern, in particular a higher consumption of vegetables, fruit, whole grains, fish and low-fat dairy, was associated with less depressive symptoms and higher optimism. However, given the cross-sectional nature of our analyses, our findings may also be explained by more optimistic participants making healthier food choices. Therefore, future prospective or interventions studies are needed to establish the direction of causality of this association.ClinicalTrials.gov NCT03192410.

Project description:Background Beyond the controlled setting of trials, scarce information exists on the burden, predictors, and outcomes associated with elevated hs CRP (high-sensitivity C-reactive protein) in "real-world" patients with myocardial infarction ( MI ). Methods and Results We included all-coming MI survivors undergoing hs CRP testing >30 days after an MI during routine health care in Stockholm, Sweden (2006-2011). hs CRP tests measured during hospitalization/emergency department visits, followed by antibiotics or indicative of acute illness, were excluded, together with patients with ongoing/recent cancer, chronic infections, or immunosuppression. Inflammation was defined over a 3-month baseline window and associated with subsequent death and major adverse cardiovascular events (composite of MI, ischemic stroke, or cardiovascular death). Included were 17 464 patients (63% men; mean age, 72.6 years) with a median hs CRP level of 2.2 (interquartile range, 1.0-6.0) mg/L and a median of 2.2 (interquartile range, 0.8-4.9) years since their MI . Most (66%) had hs CRP ≥2 mg/L, and 40% had hs CRP >3 mg/L. Lower hemoglobin, lower estimated glomerular filtration rate, and comorbidities (eg, heart failure, peripheral vascular disease, stroke, atrial fibrillation, diabetes mellitus, and rheumatoid diseases) were associated with higher odds of hs CRP ≥2 mg/L. Conversely, previous percutaneous coronary intervention, ongoing renin-angiotensin blockade, and statins were associated with lower hs CRP ≥2 mg/L odds. Patients with hs CRP ≥2 mg/L were at higher risk of major adverse cardiovascular events (n=3900; adjusted hazard ratio, 1.28; 95% CI, 1.18-1.38) and death (n=4138; adjusted hazard ratio, 1.42; 95% CI, 1.31-1.53). Results were robust across subgroups of patients and after exclusion of events occurring during the first 6 to 12 months. On a continuous scale, the association between hs CRP and outcomes was linear until hs CRP >5 mg/L, plateauing thereafter. Conclusions Most patients with MI exhibit elevated hs CRP levels. Besides identifying populations at high-inflammatory risk, this study extends the prognostic validity of this biomarker from trial evidence to real-world healthcare settings.
