Usefulness of the second derivative of the finger photoplethysmogram for assessment of end-organ damage: the J-SHIPP study

Early detection of pathological changes in the vasculature is required to identify individuals at risk of cardiovascular diseases. Noninvasive measurement of the second derivative of photoplethysmogram (SDPTG) might aid in evaluating vascular aging. Here we clarified the diagnostic significance of four SDPTG indices for end-organ damage. A total of 1613… CONTINUE READING
