Primary Institution: Örebro University Hospital
Hypothesis
We hypothesized a relation between scores of emotional stress and depression on one side and cardiological, physiological and biochemical measures of disease severity, on the other.
Conclusion
Patients with tako tsubo cardiomyopathy have altered cardiac autonomic function and a high incidence rate of borderline or definite posttraumatic stress syndrome acutely.
Supporting Evidence
- Markers of myocardial damage and heart failure were slightly to moderately elevated.
- Ejection fraction improved to normal values in all patients after 3 months.
- Two patients fulfilled criteria for posttraumatic stress syndrome while 7 patients were in the borderline zone.
- There was a statistically significant inverse correlation between PTSS-10 score and QRS duration.
Takeaway
This study looked at women with a heart condition called tako tsubo cardiomyopathy, which can happen after stress. It found that many of them also had signs of stress and anxiety.
Methodology
Patients diagnosed with tako-tsubo cardiomyopathy were extensively investigated using biochemical screening, echocardiography, cardiac MRI, heart rate variability analysis, and questionnaires for posttraumatic stress and depression.
Potential Biases
Only a subset of patients was examined by MRI and had plasma catecholamine investigations.
Limitations
The study is limited by its size and the fact that data come from a single center.
Participant Demographics
All participants were women with a median age of 70 years.
