What's the Connection? Your Heart Can Affect Your Breathing

relationship of heart lungs and brain

The heart and lungs work together to deliver oxygen to and removecarbon dioxide from the body's tissues. The functions of the heart, lungs and blood vessels are introduced through Such a condition of the blood vessel in the brain causes cerebral infarction and the. Link between brain and lung, as has been asked for, can easily be explained What is the relationship between the brain, heart, and lungs?.

Blood is supplied from the heart through the arteries and returned to the heart through the veins.

Page Top Blood flow and the arteries and the veins The blood flow centering on the heart is classified into two major types: Page Top Coronary artery and myocardial infarction A coronary artery is a route that supplies oxygen and nutrition to the heart to enable the heart to function.

If the function of the coronary artery deteriorates for some reason, oxygen shortage in the heart occurs, causing a major health problem. The condition where sufficient blood flow is impaired due to the narrowing of the interior of the coronary artery is called "heart attack" and the condition where the blood vessel is completely clogged is called myocardial infarction.

Page Top Highest blood pressure and lowest blood pressure Our arteries are elastic, much like rubber. Therefore, blood flows smoothly. When the heart contracts, the pressure on the artery becomes the highest highest pressure. When the heart expands, the pressure becomes the lowest low pressure. An excessive high blood pressure causes cerebral apoplexy or heart disease.

The researchers admit that the link between heart function and brain ageing is not yet clear. However, this is an important topic and further research to clarify the association between cardiac index and brain volume is required. Where did the story come from? The study was published in the peer-reviewed medical journal, Circulation.

This study was covered accurately by the BBC, which highlighted the preliminary nature of this research. What kind of research was this? Participants were taken from the ongoing Framingham Heart Study, a large cohort study of cardiovascular health that has followed several generations of American citizens since The researchers note that cardiomyopathy, a heart problem caused by severe wasting of the heart muscles, has been associated with dementia in previous studies.

However, it is not known how other heart diseases affect brain ageing. They suggest that the brain may be affected by problems in the heart as the brain needs adequate blood flow in order to stay healthy, and disrupted blood flow may result in damage to the brain.

As the researchers say, a cross-sectional analysis within a cohort study cannot confirm causation i. It can only suggest whether there could be an association between heart function and brain ageing.

What did the research involve? The participants in this study were recruited to the ongoing Framingham Offspring study a prospective cohort study between andand examined every four years subsequently.

This sub-study looked at data from 1, patients who had attended their seventh examination cycle and who had agreed to undergo a brain MRI study and a MRI of their heart. The participants in the study were aged between 34 and 84, with an average age of In the examination the researchers recorded blood pressure, current smoking status and any medication use. None of the included participants had dementia, nor had they had a stroke. The researchers took a brain MRI and measured the size of various brain areas and a heart MRI to look at the volume of blood passing through the heart with each heartbeat.

What were the basic results? They were interested in participants that may have subclinical heart problems i. Once they had excluded participants with cardiovascular disease from their analyses, the relationship between cardiac index and brain volume remained, although there was no association between cardiac index and heart ventricle size.
