Major Depression and Acute Coronary Syndrome-Related Factors

Pathophysiological mechanisms of post-myocardial infarction depression: a narrative review

Myocardial infarction (MI) can have significant physical and mental consequences. Depression is a prevalent psychiatric condition after MI which can reduce the quality of life and increase the mortality rates of patients. However, the connection between MI and depression has remained under-appreciated. This review examines the potential connection between depression and MI by overviewing the possible pathophysiologic mechanisms including dysregulation of the hypothalamic-pituitary-adrenal axis and autonomic nervous system, coagulation system dysfunction, inflammation, environmental factors, as well as, genetic factors. Furthermore, depression can be an adverse event of medications used for MI treatment including beta-blockers, statins, or anti-platelet agents. The need for early detection and management of depression in patients with MI is, therefore, crucial for improving their overall prognosis. Adherence to treatments and regular follow-up visits can ensure the best response to treatment.

Prevalence of Depression in Patients With Post-Acute Coronary Syndrome and the Role of Cardiac Rehabilitation in Reducing the Risk of Depression: A Systematic Review

Patients with acute myocardial infarction (AMI) or ischaemic heart disease are at risk of developing anxiety and depression. This systematic review aims to identify the various risk factors and the role of cardiac rehabilitation in reducing the risk of depression in patients after AMI. In this review, we included data on the prevalence of depression in patients post-AMI for the years 2016-2017 from a cardiac rehabilitation unit at Morriston Hospital, Swansea, a primary coronary angioplasty centre. Results from our meta-analysis were compared with the findings of previous studies. Our data showed the prevalence of depression to be 14% pre-cardiac rehabilitation and 3% post-cardiac rehabilitation. A meta-analysis of seven studies showed the prevalence to be approximately 20-35% depending on the type of questionnaire or screening method used. Gender, marital status, age, and sedentary lifestyle were found to be risk factors for depression post-acute coronary syndrome (ACS). Females, patients aged >65 years, and those who were single, lived alone, or widowed were at a higher risk of depression, and patients with sedentary lifestyles were more likely to have post-ACS depression. Depression in patients post-myocardial infarction was also associated with increased mortality and morbidity risk as well as higher hospital re-admission and future cardiac events.

The meta-analysis showed significant publication bias, studies with negative results were less likely to be published, and the study data were heterogeneous. The pooled estimate for depression estimated using the random-effects model was 1.78 (95% confidence interval = 1.58-2.01).

Prevalence of Symptoms of Anxiety Disorders and Depression in Cardiac Rehabilitation Patients in an Academic Hospital: a Case Study

The relationship between body and mind is increasingly recognized in the occurrence and prognosis of cardiac disease. Based on reports detailing the potential (and the influence of certain risk factors) of developing depression and anxiety following cardiovascular disease, or a cardiac event, most notably acute coronary syndrome (ACS), we investigated whether such symptoms also existed in patient cases found at the cardiac rehabilitation unit of an academic hospital of Eastern Ontario. We examined data from charts during a 6-year period (2012-2017). The Hospital Anxiety and Depression Scale cumulated data within a retrospective cross-sectional study, was used to estimate the prevalence of anxious and depressive symptoms that might reflect the presence of psychological distress. Overall, our sample included 1178 patient files, 81.3% of which were diagnosed with ACS and 69.6% were male. 63.1% of the patients were between 60 and 79 years old at the time of diagnosis. Most patients were Caucasian (81.1%), married (60.3%), and living with their family (74.3%), and 49.7% were recorded as overweight or obese. We found that 29.3% of patients reported symptoms of psychological distress. Regression analyses revealed strong negative correlations between the proportion of symptoms of psychological distress and factors like age and functional capacity as measured by metabolic equivalents. Significant associations were also established between symptoms of psychological distress and factors such as obesity, sedentary lifestyle, smoking, and sex (female). This study was undertaken as part of a business case to implement a new cardiac rehabilitation programme in an academic hospital of Eastern Ontario and illustrate to the managers and decision-makers, the important factors to consider and to target when developing a stepped-care program for patients in cardiac rehabilitation in order to prevent psychological distress and how such a program was relevant to their institution.

Depression and Anxiety in patients undergoing Percutaneous Coronary Intervention for Acute Coronary Syndrome

Background and Objective

Depression and anxiety are very common in patients with cardiac diseases. Percutaneous coronary intervention (PCI) has not only decreased mortality but angina, heart failure and recurrent hospitalization all are improved. Therefore, anxiety and depression associated with fibrinolytic therapy in acute coronary syndrome (ACS) are expected to be decreased in the patient undergoing PCI. Therefore, the aim of this study was to determine prevalence of depression and anxiety in patients undergoing percutaneous coronary intervention for acute coronary syndrome.

Methods

This study was conducted at Larkana Satellite Center of National Institute of Cardiovascular Diseases (NICVD), Pakistan from August 2018 to December 2018. Patients who underwent cardiac intervention within one month were enrolled in this study. Patients were interviewed regarding their basic demographics, indication for intervention and procedure details. Symptoms of anxiety were assessed using the translation of inventory of SAS (Zung's Self-Rating Anxiety Scale). Patients were interviewed for depression by using Becks depression inventory (BDI).

Results

A total of 153 patients were included in this study out of which 118 (77.1%) were males and 35 (22.5%) were females. All were married except one. Diabetes mellitus (DM) was present in 61 (39.9%), hypertension (HTN) in 69 (45.15%), obesity in 15 (9.8%), and 40 (26.1%) were smokers. Depression was present in 16 (10.5%) patients and anxiety was present in 12 (7.5%) of patients. On analysis of the association of various factor with depression; non-diabetics, housewives, laborers and uneducated were found to be more depressed. While those who smoke or earn more than 50 thousand were found less likely to be depressed.

Conclusion

Both depression and anxiety were present in only 10.5% and 7.5% of the patients after percutaneous coronary intervention for acute coronary syndrome.

Gender-Based Differences in Anxiety and Depression Following Acute Myocardial Infarction

Background

Among patients with heart disease, depression and anxiety disorders are highly prevalent and persistent. Both depression and anxiety play a significant role in cardiovascular disease progression and are acknowledged to be independent risk factors. However, there is very little gender-related analysis concerning cardiovascular diseases and emotional disorders.

Objective

We aimed to evaluate depression and anxiety levels in patients suffering from myocardial infarction [MI] within the first month after the MI and to assess the association between cardiovascular disease risk factors, demographic indicators and emotional disorders, as well as to determine whether there are gender-based differences or similarities.

Methods

This survey included demographic questions, clinical characteristics, questions about cardiovascular disease risk factors and the use of the Hospital Anxiety and Depression Scale [HADS]. All statistical tests were two-sided, and p values < 0.05 were considered statistically significant.

Results

It was determined that 71.4% of female and 60.4% of male patients had concomitant anxiety and/or depression symptomatology (p = 0.006). Using men as the reference point, women had an elevated risk of having some type of psychiatric disorder (odds ratio, 2.86, p = 0.007). The HADS-D score was notably higher in women (8.66 ± 3.717) than men (6.87 ± 4.531, p = 0.004). It was determined that male patients who developed depression were on average younger than those without depression (p = 0.005).

Conclusions

Women demonstrated an elevated risk of having anxiety and/or depression disorder compared to men. Furthermore, depression severity increased with age in men, while anxiety severity decreased. In contrast, depression and anxiety severity was similar for women of all ages after the MI. A higher depression score was associated with diabetes and physical inactivity, whereas a higher anxiety score was associated with smoking in men. Hypercholesterolemia was associated with both higher anxiety and depression scores, and a higher depression score was associated with physical inactivity in women.

Association of depression and anxiety with cardiovascular co-morbidity in a primary care population in Latvia: a cross-sectional study

BACKGROUND

Cardiovascular (CV) diseases (CVDs) are the leading cause of mortality worldwide. Globally, there is a growing interest in understanding and addressing modifiable psychosocial risk factors, particularly depression and anxiety, to prevent CVDs and to reduce morbidity and mortality. Despite the high premature mortality rate from CVDs in Latvia, this is the first Latvian study to examine the association of depression and anxiety with CVD morbidity in a primary care population.

METHODS

This cross-sectional study was carried out in 2015 within the framework of the National Research Program BIOMEDICINE at 24 primary care facilities throughout Latvia. Consecutive adult patients during a one-week time period at each facility were invited to join the study. Assessments onsite included a 9-item Patient Health Questionnaire (PHQ-9) and a 7-item Generalized Anxiety Disorder scale (GAD-7) followed by a socio-demographic questionnaire and measurements of height, weight, waist circumference, blood pressure, and total cholesterol. The diagnostic Mini International Neuropsychiatric Interview (MINI) was conducted over the telephone within 2 weeks after the visit to the general practitioner. A multivariate model was developed using binary logistic regression.

RESULTS

From the 1565 subjects (31.2% male), CVD was detected in 17.1%. Depression screening was positive (PHQ-9 ≥ 10) for 14.7%, and anxiety screening was positive (GAD-7 ≥ 10) for 10.1% of the study subjects. According to the MINI, 10.3% had current and 28.1% had lifetime depressive episode, and 16.1% had an anxiety disorder. Depression, not anxiety, was statistically significantly related to CVDs with an odds ratio (OR) of 1.52 (p = 0.04) for current depressive symptoms (PHQ-9 ≥ 10) and 2.08 (p = 0.002) for lifetime depressive episode (MINI).

CONCLUSIONS

Current depressive symptoms (PHQ-9 ≥ 10) and a lifetime depressive episode (according to the MINI) were significantly associated with increased risk of CV morbidity. Therefore, CV patients should be screened and treated for depression to potentially improve the prognosis of CVDs. Enhanced training and integration of mental health treatment in Latvian primary care settings may improve clinical outcomes.
