The relevance of physics in the causation of a HEART ATTACK

In summary, the conversation was about the topic of heart attacks and the role of different sciences, such as biology, chemistry, and physics, in understanding and explaining them. The participants discussed how physics can be related to heart attacks through understanding blood flow and the pumping actions of the heart. They also recommended researching the power inputs and stroke volumes of the heart for a better understanding. The conversation ended with a suggestion to search for cardiology tutorials for more information.

Hi there guys...this is for a project i am going to be doing for school tomorrow. The topic for my presentation is about the applications of different sciences (bio, chem, physics) and their roles in the causation of a heart attack.

But I am having difficulties finding aspects that cause a heart attack, which relates to physics. For example, in terms of biology you can discuss healthy living and how it affects the heart, for chemistry you can talk about some chemicals that lead to the blocking of nerves/veines which leads to a heart attack, etc, but i have no idea how physics can be discussed. I know it is applicable as it is applicable in anything and everything, but I am not too informed about "the heart." Do you guys know what I should look into, in terms of the physics aspects which is associated with the causing of a heart attack?

Thanks for any help.

Disclaimer: I know nothing about heart attacks, only a bit about physics.

Quote from wikipedia:
"Myocardial infarction (MI) or acute myocardial infarction (AMI), commonly known as a heart attack, is the interruption of blood supply to part of the heart, causing some heart cells to die. This is most commonly due to occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque, which is an unstable collection of lipids (fatty acids) and white blood cells (especially macrophages) in the wall of an artery. The resulting ischemia (restriction in blood supply) and oxygen shortage, if left untreated for a sufficient period of time, can cause damage or death (infarction) of heart muscle tissue (myocardium)."

From this, it seems to me that there are some physical events that cause heart attacks. So a physical explanation could try to describe this "rupture of a vulnerable atherosclerotic plaque" and how it can block the blood stream. It would be difficult to do anything quantitatively of course, but you could probably relate the probability of this "rupture"-phenomenon to the blood pressure?

First, those branches of science do not "cause" a heart attack (MI). They give us ways to understand different aspects of the MI, how it developed, what happens during the MI, and the various possible things that happen next.

Also, "blocking of nerves/veins" is not a correct term to use in the discussio of an MI. This intro page should help to get you a bit more calibrated on what causes it and what happens during an MI:

http://en.wikipedia.org/wiki/Heart_attack

As to your question, as far as physics goes, it would mainly be the blood flow and pumping actions that would be physics based. The heart is a pump, and its muscles are fed oxygen and other nutrients via the coronary arteries. It's the blocking of those arteries that causes the MI, which can lead to VF, asystole and a really bad day.

So look a bit into how fluid flows through pipes (mainly for the coronary artery part), and how a pump works in terms of stroke volume and power input, etc.

Thanks for the link. Like I said, I have no clue what causes an 'MI,' and actually don't know much about how the heart actually works. Thanks for the latter suggesstions though, but, if you mind me asking, do you know a website that has a run-down of the power inputs, stroke volumes, ect?

Thanks,

This is probably more than you want at this point, but here's a Google hit list for a search on cardiology tutorial:

http://www.google.com/search?source...lz=1T4GGLL_enUS301US302&q=cardiology+tutorial

Lots of fun stuff in there! I changed the search slightly to cardiology tutorial "stroke volume", and got some good hits:

http://www.google.com/search?source...01US302&q=cardiology+tutorial+"stroke+volume"

Looks like the 1st one on the hit list should answer your question:

I don't know if this is what you are looking for but this site helped me a lot on my last bio course. The animations are cool,the explanations are simple and there are lot of physics concepts related to the heart in there.
 

1. What role does physics play in causing a heart attack?

Physics is the study of matter, energy, and their interactions. It plays a crucial role in understanding the mechanisms behind a heart attack. The heart is a complex organ that relies on precise electrical signals and the flow of blood for its functioning. Any disruption to these processes can lead to a heart attack, and physics helps explain how these disruptions occur.

2. How does the physics of blood flow contribute to a heart attack?

Blood flow is essential for delivering oxygen and nutrients to the heart and other organs. The physics of blood flow, such as viscosity and pressure, can affect the health of blood vessels and the heart. High blood pressure, for example, can cause damage to the arteries and increase the risk of a heart attack.

3. Can physics help prevent heart attacks?

Yes, physics can help prevent heart attacks by providing insights into the factors that contribute to them. For example, understanding the laws of thermodynamics can help us make healthier dietary and lifestyle choices to maintain a healthy weight and reduce the risk of heart disease. Physics also plays a crucial role in medical imaging techniques that can detect and diagnose heart problems before they lead to a heart attack.

4. How do electromagnetism and the heart's electrical system relate to heart attacks?

The heart's electrical system, which controls the heartbeat, relies on electrical impulses to function correctly. Electromagnetism is the branch of physics that studies the relationship between electricity and magnetism. Any disruptions in the heart's electrical signals, such as arrhythmias, can lead to a heart attack. Understanding this relationship is crucial in diagnosing and treating heart conditions.

5. What are some current research areas in physics related to heart attacks?

There is ongoing research in using physics-based technologies to detect and treat heart disease. For example, scientists are developing new medical imaging techniques that use sound waves, magnetic fields, and radiation to create detailed images of the heart. There is also research into using nanotechnology to deliver drugs directly to damaged heart tissue. Additionally, physicists are studying the physics of blood flow in microcirculation, which can provide insights into how heart attacks occur and how to prevent them.
