Why the study?
Coronary artery disease causes autonomic activity anomalies, making the assessment of autonomic balance of clinical interest.
Do Poincare-derived stress score and S/PS ratio correlate with HRV parameters and differentiate autonomic dysfunction in CAD patients from healthy controls?
Population
60 male volunteers aged 50–55 years including 30 CAD patients and 30 controls
Comparison
CAD patients vs control subjects
Design
Case-control study

May aid noninvasive autonomic assessment in CAD; leaves open prospective validation before clinical use.
Do Poincare-derived stress score and S/PS ratio correlate with HRV parameters and differentiate autonomic dysfunction in CAD patients from healthy controls?
Poincare-derived stress score and S/PS ratio from short-term ECG can serve as effective markers of sympathetic activity and sympathovagal balance in patients with coronary artery disease.
