Blood Pressure01:24

Blood Pressure

9.7K
The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Measurement of Blood Pressure

2.8K
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Alterations in Blood Pressure01:30

Alterations in Blood Pressure

2.1K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Area of Science:

  • Cardiovascular Physiology
  • Hypertension Research

Background:

  • Exaggerated sympathetic cardiovascular reactivity to stress is linked to increased cardiovascular disease (CVD) risk.
  • Identifying individuals with heightened reactivity using feasible healthcare measurements is crucial.

Purpose of the Study:

  • To examine the association between home blood pressure (BP) variability and cardiac workload response to whole-body cold exposure.
  • To determine if home BP variability can identify individuals with exaggerated sympathetic responses to environmental stressors.

Main Methods:

  • Seventy-five men (55-65 years) measured home BP twice daily for a week.
  • Systolic home BP variability was computed as the standard deviation of daily means.
  • Participants underwent whole-body cold exposure (-10°C) with BP and heart rate monitored; cardiac workload was assessed via rate-pressure product (RPP).

Main Results:

  • Subjects with high systolic home BP variability showed a significantly greater RPP increase during cold exposure compared to those with low variability.
  • This heightened response was associated with augmented systolic BP changes in the high variability group.
  • Home BP variability positively correlated with cold-induced RPP and systolic BP responses.

Conclusions:

  • Moderate cold exposure increases BP and cardiac workload more in individuals with higher systolic home BP variability.
  • Elevated home BP variability may signify augmented sympathetically mediated vascular reactivity to environmental stressors.
  • Home BP variability is a potential marker for identifying heightened cardiovascular reactivity.
