Myocardial Infarction - Stress Prevention Intervention (MI-SPRINT)

January 6, 2016 updated by: University Hospital Inselspital, Berne

MI-SPRINT (Myocardial Infarction - Stress PRevention INTervention): A Randomized Controlled Minimal Early Behavioral Intervention Trial to Reduce the Development of Posttraumatic Stress Caused by Acute Myocardial Infarction

Posttraumatic Stress Disorder (PTSD) is a mental disorder that may occur after someone experiences a traumatic event. Between 10-20% of patients may develop PTSD in response to the traumatic experience of myocardial infarction (MI). PTSD is associated with impaired quality of life, social functioning, and high economic burden to the society. Posttraumatic stress attributable to MI has also been shown to be predictive of poor cardiovascular prognosis, whereby this link might relate to several atherothrombotic processes. Therefore the prevention of PTSD after MI is of high relevance. Guidelines have been published for early interventions to prevent the development of posttraumatic stress after different types of trauma but not in terms of acute MI as a traumatic event.

The overarching aim of the planned trial is to test whether a minimal behavioral intervention performed shortly after acute MI in patients at a high risk to develop PTSD and in the setting of a coronary care unit reduces the development of posttraumatic stress.

The primary hypothesis is that posttraumatic stress levels at the 3-month follow-up will be at least 20% lower in the intervention group than in the control group, and that this effect will last up to 12 months after the intervention. The secondary hypothesis is that the intervention group will show better psychosocial functioning, and a more favourable cardiometabolic biomarker profile than the control group 3 and 12 month after the intervention.

Study Overview

Detailed Description

Background

Posttraumatic Stress Disorder (PTSD) is a mental disorder that may occur after someone experiences a traumatic event. Between 10-20% of patients may develop PTSD in response to the traumatic experience of myocardial infarction (MI). Sociodemographic and psychosocial variables, including perceived distress during MI, have been identified as "risk factors" for the development of posttraumatic stress in the aftermath of MI. PTSD is associated with impaired quality of life, social functioning, and high economic burden to the society. Posttraumatic stress attributable to MI has also been shown to be predictive of poor cardiovascular prognosis, whereby this link might relate to atherothrombotic processes like endothelial dysfunction, dyslipidemia, inflammation, and coagulation. Therefore the prevention of PTSD after MI is of high relevance. Guidelines have been published for early interventions to prevent the development of posttraumatic stress after different types of trauma. A recent systematic review and meta-analysis on randomized controlled trials of early psychological interventions designed to prevent symptoms of PTSD found a benefit, but only if treatment was provided to symptomatic individuals and trauma-focused. The impact of such an intervention on posttraumatic stress in response to a myocardial infarction has not been assessed so far. The planned project is the first to test, if the development of posttraumatic stress can successfully be prevented in MI patients at high risk to develop PTSD through a minimal behavioral intervention that is feasible.

Objective

Primary aim: The overarching aim of the planned project is to investigate in a randomized-controlled trial whether a minimal (single counseling session of 45 minutes plus an information booklet) and early-on (within 48 hours after myocardial infarction) administered behavioral intervention reduces the development of clinician-rated posttraumatic stress levels attributable to MI in patients at a high risk to develop clinically relevant levels of posttraumatic stress.

Secondary aim: A further aim is to investigate whether the behavioral intervention improves psychosocial functioning and favorably affects cardiometabolic risk markers.

Methods

Patients considered to be at "high risk" to develop posttraumatic stress will be randomized to one single counseling session of 45 minutes (either targeting specific MI-triggered traumatic reactions or more general information about the role of psychological stress in coronary heart disease). The session will be performed by the study therapist in the coronary care unit within 48 hours after the patient has reached stable circulatory condition. Each patient will additionally receive written study material in the form of an information booklet. Medical variables, sociodemographic factors and cardiometabolic biomarkers will also be determined.

At 3-month and 12-month follow-up each patient will be assessed for interviewer-rated posttraumatic stress levels, psychosocial functioning, and biomarkers.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention group
Patients in the intervention group will participate in one single counseling session of 45 minutes (the minimal behavioral intervention) that targets specific MI-triggered traumatic reactions.
The minimal behavioral intervention consists of one single counseling session of 45 minutes that targets specific MI-triggered traumatic reactions. The focus of the intervention is an educational and resource-oriented approach targeting individual patient resources and cognitive (re)structuring.
Active Comparator: Control group
Patients in the control group will participate in one single counseling session of 45 minutes (the control intervention) that targets more general information about the role of psychological stress in coronary heart disease.
The control intervention consists of one single counseling session of 45 minutes that targets more general information about the role of psychological stress in coronary heart disease. Any terminology related to "trauma" will be completely avoided.
