Impact of Anxiety and Perceived Control on In-Hospital Complications After Acute Myocardial Infarction
Why the study?

Population
536 patients hospitalized for acute myocardial infarction (AMI)

Implication
High anxiety with low perceived control may flag higher AMI complication risk; hypothesis-generating for interventions targeting perceived control.
Key Points
- The study aims to investigate how perceived control affects the relationship between anxiety and in-hospital complications in acute myocardial infarction.
- Prospective examination of 536 patients hospitalized for acute myocardial infarction.
- Assessment of anxiety levels and perceived control regarding in-hospital complications.
- Multivariate hierarchical logistic regression analysis to identify predictors of complications.
- 27% of patients experienced one or more in-hospital complications.
- Higher anxiety correlated with more episodes of ventricular tachycardia, ventricular fibrillation, and reinfarction (p < .01 for all).
- Perceived control significantly reduced anxiety levels (p = .001) and moderated the relationship with complications.
Structured PICO
Do anxiety and perceived control levels predict in-hospital complications in patients with acute myocardial infarction?
P
Population
536 patients hospitalized for acute myocardial infarction (AMI)
O
Outcome
In-hospital complications (composite of recurrent ischemia, reinfarction, sustained ventricular tachycardia or fibrillation, and cardiac death)composite
High anxiety combined with low perceived control independently predicts an increased risk of in-hospital arrhythmic and ischemic complications following acute myocardial infarction.
