Insights
Heart rate (HR) can help estimate pulse wave velocity (PWV) in primary care. Specific HR thresholds after physical exertion or position changes indicate potentially high PWV, aiding early cardiovascular risk assessment.
Area of Science:
- Cardiology
- Physiology
Background:
- Cardiovascular diseases are a leading global cause of mortality.
- Pulse wave velocity (PWV) is a key predictor of adverse cardiovascular events.
- Preliminary assessment of PWV in primary care is needed.
Purpose of the Study:
- To explore methods for preliminary PWV assessment in primary care settings.
- To identify heart rate (HR) parameters indicative of elevated PWV.
Main Methods:
- 36 healthy medical students/residents (20-30 years) participated.
- Measurements included arteriograph-based PWV and treadmill physical effort (PE) testing.
- Heart rate (HR) response to PE and postural changes was recorded.
Main Results:
- High PWV may be associated with specific HR thresholds post-PE (e.g., >80 bpm after 6 min rest).
- Elevated HR (>1 min) during PE recovery or orthostatic stress (>100 bpm) suggests higher PWV.
- Resting HR >80 bpm also correlated with higher PWV.
Conclusions:
- Steady-state HR demonstrates a correlation with PWV.
- HR measurements can serve as a preliminary tool for PWV assessment in primary care.
Abstract:
Background and Objectives: Cardiovascular diseases are the main cause of death worldwide, and pulse wave velocity (PWV) is considered a predictor of major adverse cardiovascular events. The study intended to be helpful in finding methods for the preliminary assessment of PWV in primary care units. Materials and Methods: The study group consisted of 36 subjects (considered healthy by their own statement) from the medical field (medicine students and residents) aged between 20 and 30 years: 33.3% males and 66.7% females. Two types of measurements were carried out successively: (a) measurements with the arteriograph and (b) measurements on a treadmill effort testing system, where heart rate (HR) was measured over time as a response to step function physical effort (PE). Results: The study allowed for the highlighting of some limits which, if exceeded, can be associated with high PWV values: (i) if after a moderate PE and a resting time of at least 6 min, the HR is larger than 80 b/min; (ii) if the relaxation time in a PE test of moderate intensity is larger than 1 min; (iii) if the HR measured after the subject is raised from the supine to orthostatic position is larger than 100 b/min, and (iv) if the resting HR is larger than 80 b/min. Conclusions: Steady-state HR correlates with PWV and may be used for the preliminary assessment of PWV.
