Diagnostic tests and treatment procedures performed prior to cardiovascular death in individuals with severe mental illness

The epidemiology of major depression among adults in Norway: an observational study on the concurrence between population surveys and registry data - a NCDNOR project

BACKGROUND

Mental health problems, and major depression in particular, are important public health issues. Following trends in the prevalence of major depression is difficult because of the costs and complications of diagnostic interviews and general population self-report health surveys. Scandinavian countries, however, have several central, population-based health registries. We aimed to investigate how well these registries capture the epidemiology of major depression in the population.

METHODS

In two Norwegian regional surveys of general population health, each repeated after 10 years, responders were asked to report depressive symptoms using the Hopkins Symptom Checklist (HSCL) or the Hospital Anxiety and Depression Scale (HADS). Data were linked to three central health registries capturing contact with primary care, specialist care and prescriptions for antidepressants, to investigate how well these registries reflected self-reported depressive symptoms.

RESULTS

Most responders scored low on Hopkins Symptom Checklist (HSCL) and the Hospital Anxiety and Depression Scale (HADS), but 10% and 13%, respectively, scored above cut-off, with only minor changes between the two survey times. Females scored higher than males. Older people scored lower than younger, and a social gradient was visible. Around 12% of those who scored above the cut-off on either scale were recorded in the central health registries during the following year. This correlation was highest in primary care data, followed by prescription data and lowest in specialist care. Females were more often recorded in registries (p < 0.001), as were younger people (p < 0.001).

CONCLUSIONS

There was a strong association between scores on screening for major depression in the general population surveys and being recorded in central health registries. There was a low sensitivity of these registries. and there was some variation in how sensitive the central health registries were in picking up depression, especially for males and older people. However, the stability of the measures over time suggests we may get an impression of the prevalence of major depression in the general population by using data from the central health registries. A combination of primary care data, prescription data and specialist care data have a higher sensitivity.

Factors associated with medico-legal autopsy of decedents with psychiatric disorders

INTRODUCTION

Autopsy rates are declining worldwide, resulting in increasing selectivity in referral for forensic autopsy and increased uncertainty about the validity of assigned causes of death. Persons with psychiatric disorders have high rates of premature death but not all are referred for forensic autopsies. Knowledge is needed on which decedents with psychiatric disorders are chosen for forensic autopsy to determine whether causes of death are at risk of being misclassified among certain subgroups of decedents.

METHODS

We conducted a nationwide register-based case-control study including all decedents with psychiatric disorders in Denmark in the period 1998-2015. Using multivariate logistic regression, we examined associations between demographic and socioeconomic factors, comorbidities, healthcare utilization, and referral for forensic autopsy, overall and stratified by age at death (<45, 45-64, ≥65 years).

RESULTS

Of the 152,799 decedents in the study population, 7043 (4.61 %) had a forensic autopsy. Decedents referred for forensic autopsy were more likely to be young, have a history of substance use, and have schizophrenia or an affective disorder (factors listed in diminishing order of strength of association). Increasing severity of comorbidities as measured by the Charlson comorbidity index was associated with decreasing likelihood of being autopsied. Patterns of association with sex, alcohol use, habitation and education did not vary by age at death. Schizophrenia and drug use were most strongly associated with forensic autopsy in decedents < 45 years of age, whereas death early in the study period was more strongly associated with autopsy in the oldest age groups.

DISCUSSION

The decision to refer a decedent for forensic autopsy was predominantly based on the decedent's age, history of drug use, and the absence of non-psychiatric comorbidities. Causes of death in decedents with comorbidities or recent contact with the healthcare system and decedents > 65 years may be more likely to be inaccurate, particularly in drug users.

Comparative mortality risks in two independent bipolar cohorts

OBJECTIVES

To compare mortality rates in bipolar disorder with common causes of mortality.

METHODS

Observational data from the Prechter Longitudinal Study of Bipolar Disorder (PLS-BD) of 1128 participants including 281 controls was analyzed using logistical regression to quantify mortality rates in comparison with common comorbidities and causes of death. Outcome and treatment measures, including ASRM, GAD-7, PHQ-9 and medication use were used to stratify those with bipolar disorder (BD) that are alive or deceased. A larger cohort of 10,735 existing BD patients with 7,826 controls (no psychiatric diagnosis) from the University of Michigan Health (U-M Health) clinics was used as replication, observational secondary data analysis.

RESULTS

The mortality rates are significantly different between those with BD and controls in both PLS-BD and U-M Health. Those with BD and are deceased have a higher percentage of elevated depression measures but show no difference in mania or anxiety measures nor medication use patterns. In both cohorts, a diagnosis of BD increases the odds of mortality greater than history of smoking or being older than ≥ 60-years of age.

CONCLUSION

BD was found to increase odds of mortality significantly and beyond that of a history of smoking. This finding was replicated in an independent sample.

Exploring key determinants of health among individuals with serious mental Illness: qualitative insights from a first episode psychosis cohort, 20 years postdiagnosis

BACKGROUND

Individuals with serious mental illness (SMI) are more likely to experience functional decline, low well-being, comorbidities, shorter lifespan, and diminished quality of life than the general population. This qualitative study explores determinants of health that individuals with SMI perceive as important to their health, well-being, and ability to live a meaningful life.

METHOD

We conducted interviews with 13 individuals with early detected first episode psychosis as part of a 20-year follow-up study of a larger cohort. Interview data were analyzed using qualitative content analysis.

RESULTS

Analysis identified two themes comprising eight categories representing determinants of health. The first theme reflected management of mental and physical health. Categories in this theme were: access to mental healthcare adapted to individual needs, strategies during deterioration, use of psychotropic medication, maintenance of physical health and lifestyle. The second theme reflected social health determinants in coping with mental illness and comprised three categories: family and friends, engaging in meaningful hobbies and activities, and the influence of employment on mental health.

CONCLUSIONS

Individuals with SMI outlined mental, physical, and social determinants of health that were important for their health, well-being, and ability to live a meaningful life. In future clinical practice, coordinated care addressing the complexity of health determinants will be important.

Disparities in cardiovascular disease and treatment in the Nordic countries

The Nordic countries, including Denmark, Finland, Iceland, Norway, and Sweden have seen a steep decline in cardiovascular mortality in recent decades. They are among the most egalitarian countries by several measures, and all have universal, publicly funded welfare systems providing healthcare for all citizens. However, despite these seemingly ideal conditions, disparities in access to cardiovascular care and outcomes persist. To address this challenge, The Lancet Region Health-Europe convened experts from a broad range of countries to summarize the current state of knowledge on cardiovascular disease disparities across Europe. This Series Paper presents the main challenges in Nordic countries based on evidence from high-quality nationwide registries. Focusing on major cardiovascular health determinants, areas in need of improvement were identified. There is a need for addressing structural causes underlying these disparities, such as poverty and discrimination, but also to improve access to healthcare in deprived neighborhoods and to address underlying social determinants of health that may mitigate disparities in cardiovascular outcomes. Overall, while the Nordic countries have made great strides in promoting egalitarianism and providing universal healthcare, there is still much work to be done to ensure equitable access to care and improved cardiovascular outcomes for all members of society.

Effect of Telemedicine Use on Medical Spending and Health Care Utilization: A Machine Learning Approach

Introduction

This study analyzes the effect of telemedicine use on healthcare utilization and medical spending for patients with chronic mental illness.

Methods

Using the IBM MarketScan Research database from 2009 to 2018, this study examined the timing of users' first telemedicine use and identified similar periods for non-users by using random forest and random forest proximity matching. A difference-in-differences approach, which tests whether there are differences in the study outcomes before and after the actual/predicted first use among the treated group (users) compared with the control group (non-users), was then used to assess the impact of telemedicine. Analyses were done in 2021.

Results

Comparing users with non-users after matching suggested that telemedicine use both increases the number of overall outpatient visits (0.461; 95% CI=0.280, 0.642; p<0.001) related to psychotherapy and evaluation and management services, and decreases the number of in-person visits (0.280; 95% CI= -0.446, -0.114; p=0.001) for patients with chronic mental health diagnoses. Total medical spending was not significantly affected. Additionally, no evidence was found of telemedicine use being associated with an increased probability of an emergency department visit or hospitalization.

Conclusions

The study findings suggest that telemedicine use is associated with an increase in outpatient care utilization for patients with chronic mental health diagnoses. No substantive changes in medical spending, the probability of an emergency department visit, or the probability of hospitalization were noted. Results provide insights into the effect of telemedicine use on spending and healthcare utilization for patients with chronic mental illness. These findings may inform research to guide future telemedicine policies and interventions.

Cardiovascular risk factors and metabolic syndrome in patients treated with long-acting injectables antipsychotics: a retrospective study

The present cross-sectional, retrospective study aimed to assess the prevalence of cardiovascular disease (CVD) risk factors and metabolic syndrome in a sample of psychiatric patients treated with long-acting injectable antipsychotics (LAIs). The clinical charts of 120 patients, mainly diagnosed with schizophrenia (30.0%), schizoaffective disorder (15.0%), and bipolar disorder (13.3%) on LAIs therapy - initiated in the period from 2013 to 2019 and lasting at least one year - were retrospectively reviewed and related socio-demographic, clinical and laboratory variables were collected. The 70.8% of patients were treated with first-generation LAIs, and the remaining 29.2% with second-generation LAIs. The overall sample showed low compliance in performing the required exams and evaluations related to CVD risk factors. The prevalence of metabolic syndrome was 30.8%, and, considering specific CVD risk factors, 55% of the total sample reported abdominal obesity, 43.3% arterial hypertension, 41.7% low HDL-cholesterol, 25.8% hypertriglyceridemia, and 20.8% fasting hyperglycemia. Lastly, 6.7% showed prolonged corrected QT (QTc) interval at the ECG. Patients treated with LAIs should be regularly monitored for metabolic changes and CVD risk factors. Metabolic changes rapidly develop after initiating an antipsychotic therapy and these often involve parameters, that can be easily recorded in an outpatient setting (e.g. abdominal obesity and hypertension).

Coronary Artery Disease in Patients with Severe Mental Illness

Severe mental illnesses (SMI), such as schizophrenia and bipolar disorder, are associated with a decrease in life expectancy of up to two decades compared with the general population, with cardiovascular disease as the leading cause of death. SMI is associated with increased cardiovascular risk profile and early onset of incident cardiovascular disease. Following an acute coronary syndrome, patients with SMI have a worse prognosis, but are less likely to receive invasive treatment. In this narrative review, the management of coronary artery disease in patients with SMI is discussed, and avenues for future research are highlighted.

Peripheral artery disease in patients with schizophrenia as compared to controls

BACKGROUND

Patients with schizophrenia have an increased prevalence of risk factors for peripheral artery disease (PAD) and is expected to have an increased prevalence of PAD. PAD can be detected utilizing toe-brachial index (TBI) which screens for vascular pathology proximal to the toes.

METHODS

Using a cross-sectional design, we defined the subpopulations: (1) Patients diagnosed with schizophrenia less than 2 years before inclusion (SCZ < 2), (2) Psychiatric healthy controls matched to subpopulation 1 on sex, age, and smoking status, and (3) Patients diagnosed with schizophrenia 10 or more years before inclusion (SCZ ≥ 10). TBI was calculated by dividing toe pressures by systolic brachial blood pressure, and PAD was defined by TBI < 0.70. Logistic regression analysis with PAD as outcome and sex, age, smoking status, BMI, skin temperature, diagnosis of schizophrenia, and comorbidities as explanatory variables was conducted.

RESULTS

PAD was present in 26.2% of patients diagnosed with SCZ < 2 (17 of 65) and in 18.5% of psychiatric healthy controls (12 of 65) with no statistically significant difference in prevalence rates (p = 0.29). PAD was present in 22.0% of patients diagnosed with SCZ ≥ 10 (31 of 141). In logistic regression, patients diagnosed with SCZ < 2 had an increased odds of PAD with psychiatric healthy controls as reference (Odds ratio = 2.80, 95% confidence interval 1.09-7.23, p = 0.03). The analysis was adjusted for age, sex, smoking status, BMI and comorbidities such as hypertension, diabetes and heart disease.

CONCLUSIONS

This study did not find statistically significant increased prevalence rates of PAD in patients with schizophrenia even though patients with SCZ were compared to psychiatric healthy controls using TBI. Utilizing logistic regression PAD was associated with schizophrenia diagnosis within the last 2 years, age and skin temperature. As PAD is initially asymptomatic, screening could be relevant in patients with schizophrenia if other risk factors are prevalent. Further large-scale multicenter studies are warranted to investigate schizophrenia as a potential risk factor for PAD.

Severe psychiatric disorders and general medical comorbidities: inflammation-related mechanisms and therapeutic opportunities

Individuals with severe psychiatric disorders, such as mood disorders and schizophrenia, are at increased risk of developing other medical conditions, especially cardiovascular and metabolic diseases. These medical conditions are underdiagnosed and undertreated in these patients contributing to their increased morbidity and mortality. The basis for this increased comorbidity is not well understood, possibly reflecting shared risks factors (e.g. lifestyle risk factors), shared biological mechanisms and/or reciprocal interactions. Among overlapping pathophysiological mechanisms, inflammation and related factors, such as dysbiosis and insulin resistance, stand out. Besides underlying the association between psychiatric disorders and cardiometabolic diseases, these mechanisms provide several potential therapeutic targets.

Life expectancy and years of potential life lost in bipolar disorder: systematic review and meta-analysis

BACKGROUND

There is increasing research examining excess mortality in people with bipolar disorder using life expectancy and related measures, which quantify the disease impact on survival. However, there has been no meta-analysis to date summarising existing data on life expectancy in those with bipolar disorder.

AIMS

To systematically review and quantitatively synthesise estimates of life expectancy and years of potential life lost (YPLL) in people with bipolar disorder.

METHOD

We searched Embase, Medline, PsycINFO and Web of Science databases up to 31 March 2021. We generated pooled life expectancy using random-effects models, and derived YPLL summary estimate by calculating averaged values weighted by sample size of individual studies. Subgroup analyses were conducted for gender, geographical region, study period, a given age (set-age) for lifespan estimation and causes of death. The study was registered with PROSPERO (CRD42021241705).

RESULTS

Eleven and 13 studies were included in the review for life expectancy (n = 96 601) and YPLL (n = 128 989), respectively. Pooled life expectancy was 66.88 years (95% CI 64.47-69.28; I² = 99.9%, P < 0.001), was higher in women than men (70.51 (95% CI 68.61-72.41) v. 64.59 (95% CI 61.16-68.03); z = 2.00, P = 0.003) and was lowest in Africa. Weighted average YPLL was 12.89 years (95% CI 12.72-13.07), and was greatest in Africa. More YPLL was observed when lifespan was estimated at birth than at other set-age. YPLLs attributable to natural and unnatural deaths were 5.94 years (95% CI 5.81-6.07) and 5.69 years (95% CI 5.59-5.79), respectively.

CONCLUSIONS

Bipolar disorder is associated with substantially shortened life expectancy. Implementation of multilevel, targeted interventions is urgently needed to reduce this mortality gap.

Educational attainment and mortality in schizophrenia

BACKGROUND

Individuals suffering from schizophrenia have a reduced life expectancy with cardiovascular disease (CVD) as a major contributor. Low educational attainment is associated with schizophrenia, as well as with all-cause and CVD mortality. However, it is unknown to what extent low educational attainment can explain the increased mortality in individuals with schizophrenia.

AIM

Here, we quantify associations between educational attainment and all-cause and CVD mortality in individuals with schizophrenia, and compare them with the corresponding associations in the general population.

METHOD

All Norwegian citizens born between January 1, 1925, and December 31, 1959, were followed up from January 1, 1990, to December 31, 2014. The total sample included 1,852,113 individuals, of which 6548 were registered with schizophrenia. We estimated hazard ratios (HR) for all-cause and CVD mortality with Cox models, in addition to life years lost. Educational attainment for index persons and their parents were included in the models.

RESULTS

In the general population individuals with low educational attainment had higher risk of all-cause (HR: 1.48 [95% CI: 1.47-1.49]) and CVD (HR: 1.59 [95% CI: 1.57-1.61]) mortality. In individuals with schizophrenia these estimates were substantially lower (all-cause: HR: 1.13 [95% CI: 1.05-1.21] and CVD: HR: 1.12 [95% CI: 0.98-1.27]). Low educational attainment accounted for 3.28 (3.21-3.35) life years lost in males and 2.48 (2.42-2.55) years in females in the general population, but was not significantly associated with life years lost in individuals with schizophrenia. Results were similar for parental educational attainment.

CONCLUSIONS

Our results indicate that while individuals with schizophrenia in general have lower educational attainment and higher mortality rates compared with the general population, the association between educational attainment and mortality is smaller in schizophrenia subjects than in the general population.

Echocardiographic study of cardiac structure and function in people with bipolar disorder after midlife

BACKGROUND

Heart failure is the leading cause of mortality in older people with bipolar disorder (BD). Studies examining cardiac structure and function in middle-aged patients with BD by using echocardiography and cardiac strain imaging are scant.

METHODS

We recruited 48 patients with bipolar I disorder (BD-I) older than 45 years to undergo conventional and tissue speckle tracking echocardiography. Data of 31 mentally healthy adults older than 45 years were randomly retrieved from the echocardiographic dataset and compared with the data of BD patients.

RESULTS

Patients with BD-I had significantly higher mean values of interventricular septal thickness (Cohen's d = 0.83, p = 0.001) and left ventricular internal diameter (Cohen's d = 0.90, p = 0.001) at end-diastole relative to controls. Additionally, BD-I patients exhibited significantly lower mean values of mitral valve E/A ratio (Cohen's d = 0.67, p = 0.007) and a more reduced global longitudinal strain (Cohen's d = 0.72, p = 0.029) than controls. Multiple linear regression revealed that body mass index was negatively correlated with the mitral valve E/A ratio (adjustment R² = 0.363, p = 0.043) in patients with BD-I.

LIMITATIONS

A relatively small sample size may limit generalization.

CONCLUSIONS

After midlife, BD patients exhibit cardiac diastolic (low mitral valve E/A ratio) and systolic (reduced global longitudinal strain) dysfunction. High body mass index may play a role in the unfavorable cardiac function in aging patients with BD.

Mortality gap and physical comorbidity of people with severe mental disorders: the public health scandal

BACKGROUND

Patients suffering from severe mental disorders, including schizophrenia, major depression and bipolar disorders, have a reduced life expectancy compared to the general population of up to 10-25 years. This mortality gap requires urgent actions from a public health perspective in order to be reduced.

MAIN TEXT

Factors associated with the high mortality rates in patients with severe mental disorders can be grouped into four groups: those related to the patients, to psychiatrists, to other non-psychiatrist medical doctors and to the healthcare system. Each of these factors should become the target of specific and dedicated interventions, in order to reduce the morbidity and mortality rate in patients with severe mental disorders. All these elements contribute to the neglect of physical comorbidity in patients with severe mental. In particular, the long-standing separation of psychiatry from other branches of medicine and the lack of specific training on this issue further contribute to the poor attention dedicated to management of physical comorbidities. Recently, several professional associations have invited national bodies regulating education of healthcare professionals to include the management of physical health of people with severe mental disorders in undergraduate and postgraduate educational programs.

CONCLUSIONS

The premature mortality in patients with severe mental disorders is a complex phenomenon resulting by the interaction of several protective and risk factors. Therefore, a multilevel approach is needed, in which the different stakeholders involved in health care provision establish workforces for the long-term management of physical and mental health conditions.

Clinical Heart Failure Among Patients With and Without Severe Mental Illness and the Association With Long-Term Outcomes

BACKGROUND

Patients with severe mental illness (SMI) including schizophrenia, bipolar disorder, and severe depression have earlier onset of cardiovascular risk factors, predisposing to worse future heart failure (HF) compared with the general population. We investigated associations between the presence/absence of SMI and long-term HF outcomes.

METHODS

We identified patients with HF with and without SMI in the Duke University Health System from 2002 to 2017. Using multivariable Cox regression, we examined the primary outcome of all-cause mortality. Secondary outcomes included rates of implantable cardioverter defibrillator use, cardiac resynchronization therapy, left ventricular assist device implantation, and heart transplantation.

RESULTS

We included 20 906 patients with HF (SMI, n=898; non-SMI, n=20 008). Patients with SMI presented clinically 7 years earlier than those without SMI. We observed an interaction between SMI and sex on all-cause mortality (P=0.002). Excess mortality was observed among men with SMI compared with men without SMI (hazard ratio, 1.36 [95% CI, 1.17-1.59]). No association was observed among women with and without SMI (hazard ratio, 0.97 [95% CI, 0.84-1.12]). Rates of implantable cardioverter defibrillator use, cardiac resynchronization therapy, left ventricular assist device implantation, and heart transplantation were similar between patients with and without SMI (6.1% versus 7.9%, P=0.095). Patients with SMI receiving these procedures for HF experienced poorer prognosis than those without SMI (hazard ratio, 2.12 [95% CI, 1.08-4.15]).

CONCLUSIONS

SMI was associated with adverse HF outcome among men and not women. Despite equal access to procedures for HF between patients with and without SMI, those with SMI experienced excess postprocedural mortality. Our data highlight concurrent sex- and mental health-related disparities in HF prognosis, suggesting that patients with SMI, especially men, merit closer follow-up.

Mind-Body Connection: Cardiovascular Sequelae of Psychiatric Illness

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the world. Mental health disorders are associated with the onset and progression of cardiac disease. The adverse sequelae of this association include worsened quality of life, adverse cardiovascular outcomes, and heightened mortality. The increased prevalence of CVD is partly explained by increased rates of traditional cardiovascular risk factors including hypertension, hyperlipidemia, diabetes mellitus, obesity, and smoking, but mental illness is an independent risk factor for CVD and mortality. Given the association between mental health disorders and poor cardiovascular health, it is vital to have an early and accurate identification and treatment of these disorders. Our review article shares the current literature on the adverse cardiovascular events associated with psychiatric disorders. We present a review on depression, anxiety, bipolar disorder, schizophrenia, type A and D personality disorders, obsessive-compulsive disorder, and stress.

Excess mortality and life-years lost in people with bipolar disorder: an 11-year population-based cohort study

AIMS

Bipolar disorder is associated with premature mortality, but evidence is mostly derived from Western countries. There has been no research evaluating shortened lifespan in bipolar disorder using life-years lost (LYLs), which is a recently developed mortality metric taking into account illness onset for life expectancy estimation. The current study aimed to examine the extent of premature mortality in bipolar disorder patients relative to the general population in Hong Kong (HK) in terms of standardised mortality ratio (SMR) and excess LYLs, and changes of mortality rate over time.

METHODS

This population-based cohort study investigated excess mortality in 12 556 bipolar disorder patients between 2008 and 2018, by estimating all-cause and cause-specific SMRs, and LYLs. Trends in annual SMRs over the 11-year study period were assessed. Study data were retrieved from a territory-wide medical-record database of HK public healthcare services.

RESULTS

Patients had higher all-cause [SMR: 2.60 (95% CI: 2.45-2.76)], natural-cause [SMR: 1.90 (95% CI: 1.76-2.05)] and unnatural-cause [SMR: 8.63 (95% CI: 7.34-10.03)] mortality rates than the general population. Respiratory diseases, cardiovascular diseases and cancers accounted for the majority of deaths. Men and women with bipolar disorder had 6.78 (95% CI: 6.00-7.84) years and 7.35 (95% CI: 6.75-8.06) years of excess LYLs, respectively. The overall mortality gap remained similar over time, albeit slightly improved in men with bipolar disorder.

CONCLUSIONS

Bipolar disorder is associated with increased premature mortality and substantially reduced lifespan in a predominantly Chinese population, with excess deaths mainly attributed to natural causes. Persistent mortality gap underscores an urgent need for targeted interventions to improve physical health of patients with bipolar disorder.

Identification and management of cardiometabolic risk in subjects with schizophrenia spectrum disorders: A Delphi expert consensus study

BACKGROUND

Patients with schizophrenia spectrum disorders (SSD) have worse physical health and reduced life expectancy compared to the general population. In 2009, the European Psychiatric Association, the European Society of Cardiology and the European Association for the Study of Diabetes published a position paper aimed to improve cardiovascular and diabetes care in patients with severe mental illnesses. However, the initiative did not produce the expected results. Experts in SSD or in cardiovascular and metabolic diseases convened to identify main issues relevant to management of cardiometabolic risk factors in schizophrenia patients and to seek consensus through the Delphi method.

METHODS

The steering committee identified four topics: 1) cardiometabolic risk factors in schizophrenia patients; 2) cardiometabolic risk factors related to antipsychotic treatment; 3) differences in antipsychotic cardiometabolic profiles; 4) management of cardiometabolic risk. Twelve key statements were included in a Delphi questionnaire delivered to a panel of expert European psychiatrists.

RESULTS

Consensus was reached for all statements with positive agreement higher than 85% in the first round. European psychiatrists agreed on: 1) high cardiometabolic risk in patients with SSD, 2) importance of correct risk management of cardiometabolic diseases, from lifestyle modification to treatment of risk factors, including the choice of antipsychotic drugs with a favourable cardiometabolic profile. The expert panel identified the psychiatrist as the central coordinating figure of management, possibly assisted by other specialists and general practitioners.

CONCLUSIONS

This study demonstrates high level of agreement among European psychiatrists regarding the importance of cardiovascular risk assessment and management in subjects with SSD.

Management of Cardiovascular Health in People with Severe Mental Disorders

PURPOSE OF REVIEW

To review evidence regarding the association between bipolar disorder and schizophrenia, henceforth referred to as severe mental disorders (SMD), and cardiovascular morbidity and mortality, its mechanisms, and the interventions to reduce this burden.

RECENT FINDINGS

Much of the loss in life expectancy in people with SMD remains driven by cardiovascular mortality. Antipsychotics and mood stabilizers are associated with negative cardio-metabolic outcomes, but large inter-individual differences are observed, and not treating SMD might be associated with even greater cardiovascular mortality. Classical modifiable cardiovascular risk factors remained inadequately screened and, once identified, too seldom treated in people with SMD. After a myocardial infarction, aggressive tertiary prevention may be as effective in people with SMD as in the general population but is less prescribed. Reduced healthcare quality and increased prevalence of cardiovascular risk factors may not fully explain the excess cardiovascular mortality associated with SMDs, which themselves should be considered risk factors in risk calculators. Hazardous health behaviors, the cardio-metabolic adverse effects of medications, and a reduced access to quality healthcare remain priority targets for intervention.

Cardiovascular disease in patients with severe mental illness

Individuals diagnosed with schizophrenia or bipolar disorder have a life expectancy 15-20 years shorter than that in the general population. The rate of unnatural deaths, such as suicide and accidents, is high for these patients. Despite this increased proportion of unnatural deaths, physical conditions account for approximately 70% of deaths in patients with either schizophrenia or bipolar disorder, with cardiovascular disease contributing 17.4% and 22.0% to the reduction in overall life expectancy in men and women, respectively. Risk factors for cardiovascular disease, such as smoking, unhealthy diet and lack of exercise, are common in these patients, and lifestyle interventions have been shown to have small effects. Pharmacological interventions to reduce risk factors for cardiovascular disease have been proven to be effective. Treatment with antipsychotic drugs is associated with reduced mortality but also with an increased risk of weight gain, dyslipidaemia and diabetes mellitus. These patients have higher risks of both myocardial infarction and stroke but a lower risk of undergoing interventional procedures compared with the general population. Data indicate a negative attitude from clinicians working outside the mental health fields towards patients with severe mental illness. Education might be a possible method to decrease the negative attitudes towards these patients, thereby improving their rates of diagnosis and treatment.

Diagnostic tests and treatment procedures performed prior to cardiovascular death in individuals with severe mental illness

OBJECTIVE

To examine whether severe mental illnesses (i.e., schizophrenia or bipolar disorder) affected diagnostic testing and treatment for cardiovascular diseases in primary and specialized health care.

METHODS

We performed a nationwide study of 72 385 individuals who died from cardiovascular disease, of whom 1487 had been diagnosed with severe mental illnesses. Log-binomial regression analysis was applied to study the impact of severe mental illnesses on the uptake of diagnostic tests (e.g., 24-h blood pressure, glucose/HbA1c measurements, electrocardiography, echocardiography, coronary angiography, and ultrasound of peripheral vessels) and invasive cardiovascular treatments (i.e., revascularization, arrhythmia treatment, and vascular surgery).

RESULTS

Patients with and without severe mental illnesses had similar prevalences of cardiovascular diagnostic tests performed in primary care, but patients with schizophrenia had lower prevalences of specialized cardiovascular examinations (prevalence ratio (PR) 0.78; 95% CI 0.73-0.85). Subjects with severe mental illnesses had lower prevalences of invasive cardiovascular treatments (schizophrenia, PR 0.58; 95% CI 0.49-0.70, bipolar disorder, PR 0.78; 95% CI 0.66-0.92). The prevalence of invasive cardiovascular treatments was similar in patients with and without severe mental illnesses when cardiovascular disease was diagnosed before death.

CONCLUSION

Better access to specialized cardiovascular examinations is important to ensure equal cardiovascular treatments among individuals with severe mental illnesses.
