简要总结
Overall, the investigators aim to recruit 150 subjects during their hospitalization for an acute coronary syndrome (ACS). At two weeks post-ACS, the investigators will assess levels of gratitude and optimism, draw blood for baseline levels of biomarkers, gather baseline information about health behaviors critical to cardiac health, and obtain baseline measures of symptoms and function. Finally, the investigators will repeat assessments of biomarkers, behavior, and function at 6 months to allow us to assess the impact of gratitude and optimism on these outcomes; the investigators will also have an objective measure of physical activity via accelerometer (step counter) at 6 months.
Specific Aim #1: To prospectively assess the association between gratitude/optimism 2 weeks after ACS and improvement in biological markers of cardiac health at 6 months post-ACS.
Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater reductions in levels of biomarkers associated with negative heart health between 2 weeks and 6 months.
Specific Aim #2 (*primary aim*): To assess the association between gratitude/optimism 2 weeks after ACS and subsequent adherence to health behaviors known to improve post-ACS prognosis at 6 months.
Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater amounts of physical activity (measured by accelerometer) at 6 months (primary study outcome measure), and greater improvements in self-reported adherence to health behaviors (activity, diet, and medication) between 2 weeks and 6 months.
Specific Aim #3: To assess the association between gratitude/optimism at 2 weeks and non-elective cardiac rehospitalizations (and other clinical outcomes) at 6 months.
Hypothesis: Higher levels of gratitude/optimism at 2 weeks will be associated with greater improvements in depression, health-related quality of life, function, cardiac symptoms, and possibly readmissions, between 2 weeks and 6 months.
详细描述
Enrollment Patients will be enrolled during their acute admission for an ACS. At this visit, patients will be introduced to the study and given a follow-up study visit at the MGH Heart Center 2 weeks following their ACS. We will also ask them about their physical activity levels in the time before their ACS.
On the date of enrollment, study staff will estimate baseline physical activity using the Stanford 7-day Physical Activity Recall Scale (PAR). Additionally, contact information (address, phone number, email) will be obtained from the subject along with his/her social security number in order to provide a check for compensation.
Initial Evaluation:
After enrollment, subjects will have a visit 2 weeks post-ACS in the MGH Heart Center. Several procedures will occur during this visit.
- Baseline assessments. Subjects will complete self-report measures to assess the following:

入选标准
- •Adult patients admitted to cardiac units at MGH with a primary admission diagnosis of ACS (eligible patients must meet World Health Organization criteria for myocardial infarction or criteria for unstable angina [new-onset angina within 2 months, exacerbation of previous angina with rest pain or with minimal exercise, or angina within 2 weeks of MI]). ACS diagnosis will be clarified with the inpatient care team and adjudicated by co-investigator cardiologist Dr. Januzzi as needed.
排除标准
- •'Periprocedural' ACS (ACS that occurs in the setting of another medical procedure; such events may occur in the absence of structural heart disease and likely represent a different pathophysiology, course and prognosis than those with 'endogenous' ACS).
- •Conditions likely to alter biomarkers of interest (renal failure requiring hemodialysis, inflammatory disease [e.g., systemic lupus erythematosus])
- •Condition likely to lead to death within 6 months (e.g. cancer).
- •Inability to complete physical activity due to unrelated medical condition (e.g., severe arthritis)
- •Inability to complete self-report evaluations due to inability to speak or write in English or due to cognitive deficits (assessed using an established six-item screen).
