Stress-Induced Autonomic Dysfunction is Associated With Mental Stress–Induced Myocardial Ischemia in Patients With Coronary Artery Disease

Circ Cardiovasc ImagingPublished Cross-sectional study

Authors' conclusion

In individuals with coronary artery disease, mental stress-induced autonomic dysfunction may be a mechanism implicated in the causal pathway of MSIMI.

Study context

Population
Patients with stable CAD undergoing a standardized laboratory speech stressor with Holter monitoring
Participants
735 patients
Exposure
Low heart rate variability (HRV) vs high HRV during mental stress
Outcome
Mental stress-induced myocardial ischemia (MSIMI)

Main finding

As reported in the abstract

MSIMI, by HRV during stress
Low HRV vs High HRVOdds ratio (95% CI)
High-frequency HRV during stress
2.1(1.3–3.3)
Low-frequency HRV during stress
2.1(1.3–3.3)

Observational data: associations, not effects.

Further findings

Low-frequency HRV at rest also associated with mental stress-induced myocardial ischemia (MSIMI), with slightly reduced effect estimates
