Factors affecting Blood pressure01:28

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.
Physiological Factors:
Requirements for Human Life01:26

Requirements for Human Life

The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...
Blood Pressure01:30

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 diastolic...
Blood Pressure01:24

Blood Pressure

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...
Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
Special considerations while measuring blood pressure01:28

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Summary

Decreasing outdoor temperatures, specifically ambient and apparent, were linked to increased blood pressure in older men. This suggests a potential mechanism for cold-related cardiovascular mortality.

Area of Science:

  • Environmental Health
  • Cardiovascular Epidemiology
  • Biostatistics

Background:

  • Cardiovascular mortality is associated with ambient temperature fluctuations.
  • The precise mechanisms linking outdoor temperature to cardiovascular events remain unclear.
  • Elevated blood pressure is a known risk factor for cardiovascular mortality.

Purpose of the Study:

  • To investigate the association between outdoor temperature and blood pressure levels.
  • To explore potential mechanisms for temperature-related cardiovascular mortality.

Main Methods:

  • A cohort of elderly men (53-100 years) in the Boston area was studied.
  • Mixed-effects models analyzed repeated measures of systolic (SBP) and diastolic blood pressure (DBP).
  • Ambient, apparent, and dew point temperatures (DPT) were assessed, controlling for confounders like black carbon and barometric pressure.

Main Results:

  • A 5°C decrease in ambient and apparent temperature was associated with a modest increase in DBP (1.01% and 1.55%, respectively).
  • Excluding extreme temperatures strengthened these associations for DBP.
  • Similar modest increases were observed for SBP with decreasing apparent temperature.

Conclusions:

  • Cumulative exposure to decreasing ambient and apparent temperatures may elevate blood pressure.
  • Increased blood pressure due to cold exposure could be a pathway for cardiovascular mortality.
  • Findings suggest temperature effects on blood pressure are more pronounced in cold-related mortality.
