Background:
Self-management of heart failure relies on patients to assess their symptoms, but their ability to do so is often difficult to determine. The 12-item self-report Heart Failure Somatic Awareness Scale (HFSAS) was developed to measure awareness of and distress secondary to heart failure symptoms. The purpose of this study was to test the psychometric properties of the HFSAS.
Methods And Results:
Feasibility and discriminant validity of the HFSAS were tested in 49 patients admitted for an exacerbation of heart failure. The HFSAS was acceptable to patients and discriminated between heart failure symptoms and anxiety (r = 0.25, P = .08). When reliability and validity were tested in 201 patients with acute heart failure, theta reliability was adequate (0.71). The HFSAS was low to moderately correlated with general bodily awareness (r = 0.48). No difference was found based on gender, but younger patients had higher mean and median HFSAS scores (more distress). The HFSAS was a significant predictor of symptom duration prior to seeking care for heart failure; higher scores were associated with longer delay before seeking care.
Conclusion:
The HFSAS is reliable with content, discriminant, and construct validity. Evaluation of its usefulness in teaching patients to monitor daily symptoms is needed.

Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
