[New approach to understanding the hemodynamic norm]
Insights
Healthy individuals exhibit diverse hemodynamic patterns, categorized as hyperkinetic, eukinetic, or hypokinetic based on cardiac index. This hemodynamic heterogeneity in the general population may inform studies on arterial hypertension.
Area of Science:
- Cardiovascular Physiology
- Human Physiology
Context:
- Hemodynamic norms are typically considered uniform in healthy populations.
- Previous research has not extensively characterized the spectrum of hemodynamic variation in young adults.
Purpose:
- To investigate and classify hemodynamic patterns in healthy young adults.
- To explore the heterogeneity of hemodynamic norms within a healthy population.
Summary:
- This study analyzed hemodynamic values in 114 healthy individuals aged 15-34 using rheography and tachooscillography.
- Participants were categorized into hyperkinetic (23.7%), eukinetic (46.5%), and hypokinetic (29.8%) groups based on cardiac index.
- Findings support the concept of a heterogeneous hemodynamic norm in healthy individuals.
Impact:
- Provides evidence for the diverse nature of normal hemodynamics.
- Suggests using baseline hemodynamic heterogeneity as a criterion for analyzing hemodynamics in patients with arterial hypertension.
Abstract:
Hemodynamic values were studied by rheography and tachooscillography in 114 healthy individuals whose ages ranged from 15 to 34 years. According to the cardiac index value, all individuals examined were divided into 3 groups: with hyperkinetic type hemodynamics (cardiac index 5.67--4.32 l/min/m2 in males and 6.06--4.70 l/min/m2 in females), eukinetic (4.31--2,96 and 4.69--3.33 l/min/m2, respectively), and hypokinetic (2.95--1,59 and 3.32--1.95 l/min/m2, respectively). The first type was encountered in 23.7% of cases, the second in 46.5%, and the third in 29.8%. The information yielded by the study is used as evidence in favour of the assumption concerning the heterogeneous character of the hemodynamic norm among the healthy population. It is suggested that the criterion of the initial hemodynamic heterogeneity of the human population is employed in the analysis of the heterogeneity of hemodynamics in individuals with arterial hypertension.
