Key result
The Valsalva maneuver in cardiac patients with congestive failure produces a 'failure response' with maintained blood pressures during strain and absent overshoot, unlike compensated patients.
Why the study?
Does the blood pressure response to the Valsalva maneuver differ between cardiac patients with and without congestive heart failure?
Population
Cardiac patients with and without congestive heart failure, and normal subjects
Comparison
Valsalva maneuver vs Compensated cardiac patients and normal subjects
Design
Cross-sectional

May distinguish decompensated HF by Valsalva response pattern; leaves open prospective validation before clinical adoption.

Does the blood pressure response to the Valsalva maneuver differ between cardiac patients with and without congestive heart failure?
Patients with congestive heart failure exhibit a distinct 'failure response' to the Valsalva maneuver, characterized by maintained blood pressure during strain and absent overshoot, driven by elevated right ventricular diastolic pressure.
Judson et al. (1955) conducted an observational in Cardiac patients with and without congestive failure. Valsalva maneuver vs. Compensated cardiac patients and normal subjects was evaluated on Blood pressure response (systolic, diastolic, and pulse pressures). The Valsalva maneuver in cardiac patients with congestive failure produces a 'failure response' with maintained blood pressures during strain and absent overshoot, unlike compensated patients.
