Key result
Photoplethysmography is a simple and cost-effective method feasible for routine clinical screening of cardiovascular pathology and individual health monitoring via smart devices.
Why the study?
Vegetative dysfunction is considered a principal mechanism in cardiovascular pathology pathogenesis, prompting a review of photoplethysmography methods for assessing vegetative imbalance and screening cardiovascular system pathology.
Photoplethysmography offers a non-invasive, cost-effective approach for screening cardiovascular pathology and assessing autonomic dysfunction in both clinical and ambulatory settings.
May support PPG screening via wearables; leaves open outcome impact before practice adoption.
Currently, vegetative dysfunction considered to be one of principal mechanisms in the pathogenesis of cardiovascular pathology, which causes a cascade of events leading to changes in the properties and a structure of vascular wall. This review article contains literature from various databases (Russian science citation index, PubMed, Google Shcolar, Scopus). It presents the methods for assessing vegetative imbalance. In particular, the method of photoplethysmography (PPGV) is considered for recording periodic fluctuations at various frequencies in the distal vascular bed which characterize physiological processes (cardiac activity, respiratory influences, neurogenic, myogenic and endothelial activity). In addition, other diagnostic capabilities of PPGV such as heart rate (HR) assessment, determining the properties of vascular wall and the level of blood saturation are elucidated. This paper demonstrates a wide range of PPGV applications. The simplicity of PPGV reproduction and its cost-effectiveness make it feasible both in routine clinical practice for the purposes of screening for cardiovascular pathology, and for individual health monitoring incorporated in smart devices.
