Reducing stress and anxiety in patients with myocardial infarction with non-obstructive coronary arteries or Takotsubo syndrome: A non-randomized feasibility study

Mental health status and quality-of-life after an acute myocardial infarction with non-obstructive coronary arteries or takotsubo syndrome: A systematic review

BACKGROUND

Myocardial infarction with non-obstructive coronary arteries (MINOCA) and takotsubo syndrome (TS) are both characterised by lack of significant coronary artery stenoses and a higher prevalence of mental health disorders preceding the event. Currently, little is known about their pathological aetiologies and subsequent treatment plans, giving cause for concern among those affected. The objective of this review is to provide a comprehensive overview of mental health status and quality of life (QoL) in MINOCA- and TS-patients after the acute event, compared to both cardiac and non-cardiac populations, and over time.

METHODS

A systematic search was conducted via Cochrane Library, CINAHL, PyschINFO, PubMed, ASSIA, Web of Science, Scopus and Embase from inception to May 2024. The review was registered in PROSPERO and methods, and results were reported in accordance with the PRISMA guidelines. Quality assessment and risk of bias were evaluated using the Newcastle-Ottawa Scale for cross-sectional and cohort studies.

RESULTS

Sample sizes ranged from 13 to 5,322 participants. The risk of bias was high in 18/28, medium in 7/28, and low in 3/28 studies. Across the symptoms assessed, MINOCA- and TS-patients reported worse mental health status or QoL than non-cardiac groups in 10/13 studies, and cardiac groups in 10/20 studies. Investigating change over time, 1/5 studies found deteriorating mental health status, 3/5 reported improved mental health status or QoL and 1/5 reported no change in MINOCA- and TS-patients.

CONCLUSIONS

Patients with MINOCA or TS seem to have worse mental health status and QoL after the acute event than non-cardiac individuals, but it is yet difficult to conclude whether mental distress and QoL are equal or worse compared to CHD-patients. There is no convincing evidence that mental health status or QoL of MINOCA- and TS- patients naturally improve over time after the acute event. Among the studies evaluated, risk of bias was high. More high-quality studies are needed, investigating mental health status and QoL among MINOCA- and TS-patients.

Mobile health delivered physical activity after mild stroke or transient ischemic attack: Is it feasible and acceptable?

BACKGROUND AND AIMS

Physical activity is a key component of secondary stroke prevention. Mobile health (mHealth) interventions show promise for enhancing post-stroke physical activity, but most studies have combined mHealth with onsite services. This study evaluated the feasibility and acceptability of a fully digitalized mHealth intervention for physical activity among individuals post-stroke or transient ischemic attack (TIA) in Sweden.

METHODS

In this two-arm feasibility randomized controlled trial, adults with stroke or TIA were randomized to one of the following 6-month interventions: (1) the experiment group, receiving mHealth-delivered supervised exercise (two sessions weekly during months 1 to 3, one session weekly during months 4 to 6) and behavioral change techniques for physical activity (including two individual counseling and six follow-up sessions) or (2) the control group, receiving two mHealth-delivered individual counseling and three follow-up sessions. Feasibility (reach, retention, adherence, fidelity, safety) and acceptability were assessed according to pre-specified progression criteria.

RESULTS

Of 114 participants, 105 (92%) completed the 6-month intervention and 102 (89%) completed the 12-month follow-up assessment. The intervention reached individuals from 20 of 21 Swedish regions. Sixty-eight percent of participants had a stroke (of which 96% were mild), 64% were female, and the average age was 71 years (standard deviation = 9). Ninety-five percent were born in Sweden, had a high level of education (61%), and an average daily step count of 6451 steps. Completion of outcome measures included digital questionnaires (98%), sensor-derived physical activity (92%), and blood pressure monitoring (97%). A total of 1781 supervised exercise sessions were delivered to the experiment group, with an adherence rate of 76%, and adherence to individual counseling and follow-up sessions was 96%. Ninety-five adverse events were recorded, of which 16 were related to the intervention (predominantly pain or muscle soreness) but non-serious. Overall satisfaction with the mobile app was 71%, and 76% of the experiment group believed the app could partly replicate in-person visits.

CONCLUSION

The mHealth intervention was overall feasible and acceptable; however, there is a need to develop recruitment procedures to increase diversity of included participants regarding socioeconomic status and physical activity level, prior to a phase 3 trial.

Psychosocial Factors of Women Presenting With Myocardial Infarction With or Without Obstructive Coronary Arteries

BACKGROUND

Women with myocardial infarction (MI) are more likely to have elevated stress levels and depression than men with MI.

OBJECTIVES

We investigated psychosocial factors in women with myocardial infarction with nonobstructive coronary arteries (MINOCA) and those with MI and obstructive coronary artery disease (CAD).

METHODS

Women with MI enrolled in a multicenter study and completed measures of perceived stress (Perceived Stress Scale-4) and depressive symptoms (Patient Health Questionnaire-2) at the time of MI (baseline) and 2 months later. Stress, depression, and changes over time were compared between MI subtypes.

RESULTS

We included 172 MINOCA and 314 MI-CAD patients. Women with MINOCA were younger (age 59.4 years vs 64.2 years; P < 0.001) and more diverse than those with MI-CAD. Women with MINOCA were less likely to have high stress (Perceived Stress Scale-4 ≥6) at the time of MI (51.0% vs 63.0%; P = 0.021) and at 2 months post-MI (32.5% vs 46.3%; P = 0.019) than women with MI-CAD. There was no difference in elevated depressive symptoms (Patient Health Questionnaire-2 ≥2) at the time of MI (36% vs 43%; P = 0.229) or at 2 months post-MI (39% vs 40%; P = 0.999). No differences in the rate of 2-month decline in stress and depression scores were observed between groups.

CONCLUSIONS

Stress and depression are common among women at the time of and 2 months after MI. MINOCA patients were less likely to report high stress compared with MI-CAD patients, but the frequency of elevated depressive symptoms did not differ between the 2 groups. Stress and depressive symptoms decreased in both MI-CAD and MINOCA patients over time.

Internet-Delivered, Therapist-Assisted Treatment for Anxiety and Depression in Patients with Cardiovascular Disease: Evidence-Base and Challenges

PURPOSE OF REVIEW

This review focuses on the efficacy of internet-based psychological interventions for patients with cardiovascular disease (CVD) and comorbid anxiety and depression. Anxiety and depression comprise barriers for treatment adherence and are associated with poorer patient-reported and clinical outcomes, and greater health care costs.

RECENT FINDINGS

Internet-based, therapist-assisted interventions targeting anxiety and depression can be as efficacious as face-to-face therapy and may have some advantages, as patients can do it from their own laptop/smartphone at home at a time of their convenience, which may facilitate a better integration in their lives. To enhance the field of internet-based therapy for patients with CVD, we need to involve patients in the development of interventions, focus on developing standards for adherence and assessment of fidelity, and assess and augment health literacy in patients to safeguard equality in health care.

The e-mental health treatment in Stockholm myocardial infarction with non-obstructive coronaries or Takotsubo syndrome study (E-SMINC): a study protocol for a randomised controlled trial

BACKGROUND

In the aftermath of a myocardial infarction with non-obstructive coronary arteries (MINOCA) or Takotsubo syndrome (TS), patients commonly express high levels of stress and anxiety. Current treatment alternatives rarely address these issues.

METHODS

The study is a randomised controlled trial, where 90 patients with a discharge diagnosis of MINOCA or TS who also report symptoms of stress or anxiety will be randomised 2-6 weeks after their cardiac event. The treatment consists of 10 weeks of Internet-based cognitive behaviour therapy (CBT) and starts immediately after randomisation for the treatment group. The control group receives usual care. Main outcomes are symptoms of anxiety measured with the Hospital Anxiety and Depression scale, anxiety subscale, and perceived stress measured with the Perceived Stress Scale, 14-item version, 10 weeks after randomisation. Secondary measures include cardiac specific anxiety, symptoms of post-traumatic stress, quality of life, cortisol measured in hair and physiological stress responses (heart rate variability, blood pressure and saliva cortisol) during a stress procedure. Ten weeks after randomisation, the control group will also receive treatment. Long-term follow-up in the self-report measures mentioned above will be conducted 20 and 50 weeks after randomisation where the total group's development over time is followed, and the groups receiving intervention early versus late compared.

DISCUSSION

At present, there are no randomised studies evaluating psychological treatment for patients with MINOCA or TS. There is an urgent need for treatment alternatives aiming at relieving stress and anxiety considering the high mental stress and anxiety levels observed in MINOCA and TS, leading to decreased quality of life. CBT aiming at reducing mental stress has been shown to be effective regarding prognosis in patients with coronary artery disease. The current protocol describes a randomised open-label controlled trial evaluating an Internet-based CBT program for reduction of stress and anxiety in patients with increased mental stress and/or anxiety with a discharge diagnosis of either MINOCA or TS.
