Define cardiac arrest, heart failure, heart attack. Thanks?

Question

hahaha..hygrader...sounds like somebody needs a break....

Answer 1

Cardiac arrest is when the heart stops, so there is no circulation. Heart failure means your heart muscle does not pump as much blood as your body needs. Failure does not mean that your heart has stopped. It means that your heart is not pumping as well as it should. A heart attack occurs when one or more of the coronary arteries are blocked.

Answer 2

Like some other posters have said heart attack and cardiac arrest are different. Here is to put it simple: Heart attack is caused by blockage in an artery which causes ischemia. That is a lack of oxygen to that part of the heart and if not treated quickly it can die. The heart has different areas that can be affected. One of the first things that are done is a 12-lead EKG to see if it is a heart attack or angina. When ST-Segment elevation is noticed in two or more leads than it is most likely a heart attack. Keep in mind other conditions can cause this. Treatment for a heart attack is blood thinners like Heparin, going to the cath lab to remove the blockage, and possible open heart surgery for a bypass. Patients are also given medication for pain and oxygen. Many people survive heart attacks. I have seen many where some survived where others have died. If the LAD is blocked than there is a 95% chance of going into cardiac arrest. This is also known as the "widow maker" I have seen people live and die. Those that lived got to a cath lab very quickly. When someone is in cardiac arrest than the heart has stopped and so has the breathing. This can be caused by numerous things including: Drugs Heart attack Hypothermia Trauma to chest or any other crucial body part Hypovolemia which is blood loss Too much potassium and many other things. The news reports have said that he most likely died from cardiac arrest but so does everyone. The question is WHAT CAUSED THE CARDIAC ARREST. It will not be known until autopsy and they can look at the heart and tell if it was from a heart attack. The other kid is 100% right but just remember, until autopsy they will not know if it was indeed a heart attack. I have seen both. Heart attacks and cardiac arrest. Most do NOT survive cardiac arrest. It requires aggressive CPR, medications, and possibly defibrillation depending on the rythym. Hope this helps

Answer 6

Medical Term For Heart Attack

Answer 7

CARDIAC ARREST-is a situation when the heart did not complete the breathing process.
HEART FAILURE-the heart refuse the pumping .
HEART ATTACK-if somebody job everyday and has no resting days.

Answer 8

cardiac arrest
Sudden cessation of heartbeat and cardiac function, resulting in the loss of effective circulation.

heart failure
1. Cessation of normal heart function.
2. The inability of the heart to pump blood at an adequate rate, resulting in congestion in the lungs, shortness of breath, edema in the lower extremities, and enlargement of the liver.

heart attack
Sudden interruption or insufficiency of the supply of blood to the heart, typically resulting from occlusion or obstruction of a coronary artery and often characterized by severe chest pain. Also called myocardial infarction.

Answer 9

A CARDIAC ARREST, or circulatory arrest, is the abrupt cessation of normal circulation of the blood due to failure of the heart to contract effectively during systole.[1]

The resulting lack of blood supply results in cell death from oxygen starvation. Cerebral hypoxia, or lack of oxygen supply to the brain, causes victims to lose consciousness and to stop breathing, which in turn causes the heart to stop. Brain damage is likely to occur after 3-4 minutes, except in cases of hypothermia. To improve survival and neurological recovery immediate response is paramount.[2]

Cardiac arrest is a medical emergency that, in certain groups of patients, is potentially reversible if treated early enough. When cardiac arrest leads to death this is called sudden cardiac death (SCD).[1] The primary first-aid treatment for cardiac arrest is cardiopulmonary resuscitation (commonly known as CPR).

Acute myocardial infarction (AMI or MI), commonly known as a HEART ATTACK, is a serious, sudden heart condition usually characterized by varying degrees of chest pain or discomfort, weakness, sweating, nausea, vomiting, and arrhythmias, sometimes causing loss of consciousness. It occurs when the blood supply to a part of the heart is interrupted, causing death and scarring of the local heart tissue. Since the area affected may be large or small, the severity of heart attacks vary, but they are often a life-threatening medical emergency which demand both immediate attention and activation of the emergency medical services.

Diagnosis is by the combination of medical history, ECG findings and blood tests for cardiac enzymes. The most important treatment in myocardial infarction is restoring the blood flow to the heart, by thrombolysis (enzymatically dissolving the clot in the artery) and/or angioplasty (using a balloon to push the artery open). Close monitoring on a coronary care unit is mandatory to observe for various complications. There is emphasis on secondary prevention, the elimination of risk factors that could lead to further heart attacks.

The medical term myocardial infarction derives from myocardium (the heart muscle) and infarction (tissue death), in this case caused by an obstruction of blood flow. The phrase "heart attack" is occasionally used to refer to heart problems other than a myocardial infarction, such as unstable angina pectoris.

Congestive heart failure (CHF), also called congestive cardiac failure (CCF) or just HEART FAILURE, is a condition that can result from any structural or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body. It is not to be confused with "cessation of heartbeat", which is known as asystole, or with cardiac arrest, which is the cessation of normal cardiac function in the face of heart disease. Because not all patients have volume overload at the time of initial or subsequent evaluation, the term "heart failure" is preferred over the older term "congestive heart failure". Congestive heart failure is often undiagnosed due to a lack of a universally agreed definition and difficulties in diagnosis, particularly when the condition is considered "mild".
