Sphymocor Px

SphygmoCor Px system, which provides key heart function parameters and central blood pressures for the assessment and management of cardiovascular risk and disease. The system appropriately derives the calibrated blood pressure waveform at the ascending aorta from a transcutaneous that records the radial artery pressure waveform.

Features:
From the aortic pressure waveform, the system calculates a range of indices of arterial stiffness, ventricular-arterial interaction, and cardiac function, such as:
* Diastolic perfusion pressure and cardiac reserve index, key parameters affecting MI risk
* Aortic augmentation index (AIx), a measure of systemic arterial stiffness
* Central pulse pressure, an improved measure of stroke risk
* Aortic systolic pressure (Sp), which can differ markedly from brachial Sp
* LV load and systolic after load, key parameters affecting LV hypertrophy risk
* Ejection duration (ED) and subendocardial viability ratio key parameters for distinguishing systolic vs. diastolic dysfunction, and for managing efficacy of CHF therapy

Benefits:

* Provides a clinical tool to diagnose and manage arterial stiffening due to aging and disease
* Improves characterization and stratification of CV risk
* Provides a powerful clinical capability for managing CHF patients with diastolic dysfunction
