Abstract

In the last four decades, hypertension doubled to 1.13 billion patients. High blood pressure (BP) is the main risk factor for cardiovascular morbidity and mortality. Arterial stiffness (AS) is a key component and poorly understood part of cardiac vital signs. Pressure-volume loop (PULoop) has been used to measure local pulse wave velocity (PWV) which is an indicator of AS [1]. We have been able to measure the PU-Loop noninvasively on palmar digital arteries. Pressure and flow waveforms are measured simultaneously at the same location. The dataset has calculated the normalized PWV of 1.48±0.4 from the slope of the line formed between two early systole points of 20-30%. PU-Loop provides an insight into contractility, preload, and hypertension and correcting factor for pulse transit time estimations.
