Is blood pressure response to the Valsalva maneuver related to neurohormones, exercise capacity, and clinical findings in heart failure?
OBJECTIVES To investigate the relationship of the BP response to the Valsalva maneuver (VM) to parameters of congestive heart failure (CHF) other than hemodynamic measures. DESIGN Comparison of neurohormones (atrial natriuretic peptide [ANP], brain natriuretic peptide [BNP], norepinephrine [NE]), parameters of spiroergometry, and clinical parameters with BP response to the VM. SETTING Terti...
متن کاملPulse pressure response to the strain of the valsalva maneuver in humans with preserved systolic function.
Arterial pulse pressure response during the strain phase of the Valsalva maneuver has been proposed as a clinical tool for the diagnosis of left heart failure, whereas responses of subjects with preserved systolic function have been poorly documented. We studied the relationship between the aortic pulse amplitude ratio (i.e., minimum/maximum pulse pressure) during the strain phase of the Valsal...
متن کاملBlood pressure responses to the Valsalva maneuver in cardiac patients with and without congestive failure.
Compensated cardiac patients, like normal subjects, on performing the Valsalva maneuver show a decrease in systolic, diastolic, and pulse pressures during the blowing effort and a characteristic hy-pertensive overshoot after the release of the strain. Cardiac patients in congestive failure show the "failure response" with a maintenance of the systolic, diastolic, and pulse pressures during the ...
متن کاملNoninvasive evaluation of pulmonary capillary wedge pressure by BP response to the Valsalva maneuver.
STUDY OBJECTIVES To determine the BP response to the Valsalva maneuver (VM) at baseline and after changes in therapy and to compare this response to the invasively measured pulmonary capillary wedge pressure (PCWP). DESIGN Comparison of the BP response to the VM with invasively measured PCWP. In a subset of patients, direct PCWP and pulse amplitude ratio (PAR) measurements were repeated (mean...
متن کاملPressure flow studies in patients having a pressor response to the Valsalva maneuver.
a pressor response to the Valsalva maneuver. Beat-to-beat changes in stroke volume, blood pressure, pulse pressure, peak blood flow, duration of systole, duration of ejection, and heart rate were calculated. Stroke volume and blood pressure rose with the onset of straining; blood pressure rose slightly further as stroke volume fell to below control levels at the end of the straining period. Pul...
