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

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.
