Objective and Subjective Multidimensional Sleep Health in Women After Myocardial Infarction
- Multivariable regression of actigraphy and sleep diary measures
- 7 nights of wrist actigraphy
Authors' conclusion
Many women with prior MI had suboptimal sleep (short or long sleep duration, low sleep efficiency, and/or long WASO). Our results highlight the importance of discussing multiple dimensions of sleep with women post-MI to optimize cardiovascular health.
Study context
- Population
- Women with prior myocardial infarction (MI)
- Participants
- 94 post-MI women
Main finding
As reported in the abstract
Sleep measures
Mean sleep duration
405.1 minutes (approximately 6.8 hours)
Sleep efficiency
86.3%
Wake after sleep onset (WASO)
61.6 minutes
Self-reported sleep quality
3.3
Further findings
Prevalence of suboptimal sleep
- Short (<7 hours) or long (>9 hours) sleep duration
- 64.9%
- Low sleep efficiency (<85%)
- 33%
- Long WASO (>30 minutes)
- 88.3%
Participant characteristics
- Median days since MI
- 93; IQR: 69-709
- Mean age
- 60 years
- Non-Hispanic White
- 67.0%
Factors associated with poor sleep
- Identifying as other than non-Hispanic White (shorter sleep duration, lower efficiency, and longer WASO)
- Being nonpartnered (shorter sleep duration)
- Hypertension (lower sleep efficiency)
- Higher depressive symptoms (lower sleep quality)
- exploratory analyses
