What are the most common causes coronary heart disease?
Coronary heart disease occurs when the coronary artery that brings oxygen to the heart muscle become narrowed or obstructed because of the buildup of fat/cholesterol within the gut wall.In the event the build-up is just mild, symptoms could have a feeling of pressure or tightness in the chest occasionally of greater activity or stress and/or shortness of breath or fatigue with physical exertion. After the blood circulation to the heart muscle is severely reduced, chest pain (angina), heart attack (myocardial infarction) or heart rhythm disturbances (arrhythmia) can occur.In New Zealand, 180,000 people (or just one in twenty adults) you live with cardiovascular disease and every 90 minutes someone dies from the disease.Causes and risk factorsThe center is just a muscle that pumps blood to all parts of the human anatomy. After the heart chambers arrangement, blood is pumped from the center through the aorta (the major artery from the center ) carrying nutrients and oxygen into the rest of the body. One's center itself also needs oxygen to operate. It's the duty of the coronary artery to deliver oxygen-filled blood to the heart muscle.Cardiovascular disease is also called coronary cardiovascular disease, ischaemic heart disease, and coronary heart disease. It is the result of the narrowing or blockage of coronary arteries by plaque formed by fat/cholesterol to the artery walls (a process known as atherosclerosis).There are many risk factors related to cardiovascular disease. Some of these risk factors may be controlled through lifestyle medications or changes, while others can't. Controllable factors include:High blood cholesterolSmokingHigh Blood pressureType 2 diabetesPhysical inactivityFatPoor dietStress/anxiety.Non-controllable Aspects include:AgeGenderEthnicityFamily backgroundMedical history.The affliction affects men more commonly than premenopausal ladies. However, after menopause, the prevalence in women rises to be virtually the same as men. Men more than 45 decades and women older than 55 years are at increased risk.For more details - Health Education For Coronary Heart Disease Patient - Abudo
How can someone under 25 die of heart disease while appearing healthy?
How can someone under 25 die of heart disease while appearing healthy?There are 3 main reasons for deaths from heart disease in young adults.Heart muscle disease like hypertrophic cardiomyopathy (thickening of the heart muscle)Arrhythmia, abnormal heart rhythms can cause cardiac arrestHeart defects; congenital is the most commonMost young adults rarely get annual check ups and problems with their hearts are seldom caught ahead of time.
Anatomy homework clinical case study help.?
I actually don't think this is an MI (heart attack). I think this is hypokalemia and possible heart failure from an overdose of the HCTZ. HCTZ is a diuretic and it sounds like he is forgetful with the Alzheimer's and took too many of the pills. I could be wrong, though! So- 1) HCTZ overdose and subsequent hypokalemia and and hypotension that could be leading him into heart failure 2) Probably for hypertension or a past case of congestive heart failure (left sided heart failure) 3) From overdosing on HCTZ which can lead to depleted levels of potassium (hypokalemia) which can head to irregular heart rate and crushing chest pain and heart failure. All the other symptoms like low heart rate, low blood pressure, diaphoresis, confusion, distress, etc also fit with symptoms of a HCTZ overdose (according to my pharmacology textbook). 4) Fluids and electrolytes to restore his blood volume and electrolyte balance 5) Chronic gingivitis can lead to atherosclerosis and that can lead to a heart attack. Chronic inflammation like gingivitis can lead to heart disease. I hope this was correct. I'm not 100% sure. But I think saying it's just a heart attack is ignoring some of the important signs. His BP and pulse would not be that low and why would they mention the HCTZ? Best Wishes, Tiffany
Would a syringe full of air cause a heart attack?
No, a very large amount of air would need to actually be pumped into a vein in order to create difficulties on the cardiac level.
Is it normal to have your heart upside-down?
Good question by the way. Had to do a lot of research on this one to find the name. I am not a doctor, but from what I found this is called Situs Inversus. It is not a disease though, it is a condition. It is not common and is rare. Situs Inversus is a rare heart condition characterized by abnormal positioning of the heart. In this condition, the tip of the heart (apex) is positioned on the right side of the chest. Additionally, the position of the heart chambers is reversed. However, most affected individuals can live a normal life without associated symptoms or disability. Many times with situs inversus the liver and spleen are reversed also, but you did not say anything about that. Also the person who has this, they should ask their doctor to ensure the name I have given is correct. I feel it is after the research I have found. Click these links, if you would like to read up on it: http://www.healthatoz.com/healthatoz/Atoz/common/standard/transform.jsp?requestURI=/healthatoz/Atoz/ency/situs_inversus.jsp http://www.emedicine.com/radio/topic639.htm http://www.medterms.com/script/main/art.asp?articlekey=5499 http://healthlink.mcw.edu/article/901226430.html http://en.wikipedia.org/wiki/Situs_inversus Hope this helps, best wishes.
What exactly happens, in an anatomy level, when your heart stops beating?
Referred to as cardiac arrest (SCA).Usually occurs due to a myriad of different arrhythmia's (irregular heart beatings) caused by the hearts own electrical system (cardiac conducting system) as well as a result of a massive or multiple heart attacks where heart muscle (myocardium) dies.The electrical system starts in the right atrium, the sinoatrial node (SA node) where electric signals are sent through the hearts nerves causing the muscle to contract and beat. There are various stages (systole, diastole) and each can be effected contributing to SCAVentricular Fibrillation (v-fib) is an arrhythmia that often causes SCA. The ventricles in the heart (that pump blood to lungs and rest of body) quiver and don’t work properly, effectively stopping the hearts function.Another; Coronary Heart Disease (CHD) is caused by plaque buildup in the coronary arteries which supply the myocardium from the aorta. This can lead to heart attack, causing scar tissue in the myocardium, causing degeneration of the hearts cardiac conduction system where ECG leads monitor your hearts ‘beat’ by providing information on the electric signals of each rhythm. When the electrical system is compromised, either by heart failure, neurological degeneration, old age, other primary conditions etc, the heart eventually fails and stops.That’s why cardio (heart) exercise is good for your heart. It improves the coronary vessel infrastructure and aids in fat loss around rest of your body which may be a contributing factor to heart disease and consequent SCA.For more reading:Your Heart's Electrical SystemWhat Is Sudden Cardiac Arrest?
Why is a myocardial infarction called "heart attack?"?
it's not an actual attack, if you did your homework so, based on that, it's just a layman term because no one outisde the medical community would recognize myocardial infarction faster than heart attack meaning: if you say myocardial infarction, you'll get funny looks. if you say heart attack, everyone will have that enlightened "Ohhh..." reaction
What organ is under the heart? What are its functions?
There are lots of great resources out there for understanding basic human anatomy. This link is a pretty cool way to check out the human body in layers and systems so that you can get a better idea of what everything does and where it is in the body: Explore the Human Anatomy in 3DIn a person with normal anatomy, the heart sits on the centre/left side of the chest. Depending on the size of the liver (more of it on the right side under the lungs) will be on the border of the right side of the heart. Underneath the apex (bottom) of the heart is the stomach and on the left side is the spleen. Your stomach is responsible for digestion, breaking down food for fuel. Your spleen is a busy little organ that helps to recycle red blood cells and is a storage spot for platelets (for clotting) and white blood cells (immune system). The spleen is well protected- tucked under the rib cage to prevent trauma to it. On the back side of the body are the kidneys (filter toxins out of the blood, maintain hydration status, sodium/potassium balance, red blood cell production and much more) with small adrenal glands on the top of them (stress hormone production and much more). Underneath all that are your intestines- large and small, which are involved in the digestion process- breaking down food and absorbing nutrients and water.Surprisingly, some people can have medical conditions where the organs are on the reverse side of the body (called situs inversus) or in incorrect spots (situs ambiguus/heterotaxy), making normal landmarks useless. Some individuals with these conditions have normal functioning, as their organs are just a mirror image of normal anatomy, while others may have medical conditions such as heart disease.
