What is the difference between heart attack and heart failure?

Blocked artery: Heart attacks are almost always caused by a blockage in one of the arteries that supplies the heart. This stops the flow of blood (and oxygen) to that area of the heart and eventually the involved area of muscle dies. Heart failure is most often the result of several small or one large heart attack that affects enough muscle to keep the heart from being able to pump blood effectively. ...Read more

Heart Failure (Definition)

Heart failure is a complex set of conditions in which the heart "fails" to pump a normal amount of blood with each beat. This can be due to poor squeezing function (systolic heart failure) and/or a stiff heart incapable of filling normally (diastolic heart failure). Common symptoms include swelling and trouble breathing, particularly when ...Read more

Please tell me, could you explain me what's the difference between heart attack and heart failure?

Please tell me, could you explain me what's the difference between heart attack and heart failure?

Heart attack: Heart attack is also called myocardial infarction. It is death of some amount of heart muscle caused by blockage of a heart artery and can result in sudden death. Heart failure is when the heart is not pumping adequately to supply the body's need for blood flow. It can be caused by heart attack or other abnormalities. ...Read more

Could a specialist please explain to me what's the difference between heart attack and heart failure?

Could a specialist please explain to me what's the difference between heart attack and heart failure?

Acute vs chronic: A heart attack [myocardial infarction (MI)] is the death of a portion of the heart muscle that occurs when the artery supplying blood closes. It happens iin minutes to hours. Heart failure is a chronic condition where the heart cannot pump enough blood for the body due to weakness from prior MIs valve disease, chemotherapy or viral infection and fluid backs up into the lungs due to failing pump. ...Read more

What is the difference between a heart attack, heart failure and cardiac arrest?

What is the difference between a heart attack, heart failure and cardiac arrest?

Heart, chf: A heart attack is when a blood vessel to the heart blocks off and a part of the heart is damaged. A cardiac arrest can be the result of a heart attack. Cardiac arrest is when the heart suddenly stops pumping for one reason or another. A heart attack can cause cardiac arrest. A cardiac arrest isn't necessarily caused by a heart attack. Heart failure is when the heart can't supply the body's demands ...Read more

What is the difference between cardiac arrest, a heart attack and heart failure?

What is the difference between cardiac arrest, a heart attack and heart failure?

See below ...: cardiac arrest: pumping or rhythm abnormality so severe that the flow of blood thought the heart is super low or zero - incompatible with life unless successfully treated. heaty attack - region of heart muscle get less oxygen than it needs so the muscle dies. heart failure - heart is unable to adequately deliver oxygen to the body, or requires an unhealthy amount of filling pressure to do so. ...Read more

Is there a relationship between coronary heart disease, angina, heart failure and heart attack?

Is there a relationship between coronary heart disease, angina, heart failure and heart attack?

Continuum: Coronary disease develops from our lifestyle and as we age real blockage develops in some or all coronary vessels. One or more plaques disrupt and obstruct. If adequate collateral pathways exist may just vagus transient angina or pain. Angina is pain without damage. If not adequate flow, or collateral, acute myocardial infarction- heart attack occurs and that is "damage". Heart failure may follow. ...Read more

What's the difference between heart failure, heart stroke, and heart attack? If they're basically the same, shouldn't the name be, too?

What's the difference between heart failure, heart stroke, and heart attack? If they're basically the same, shouldn't the name be, too?

Difference....: They are different. A heart attack is when a blockage occurs in one (or more) of the blood vessels that supplies blood to the heart muscle. Heart failure is when the heart is not able to pump adequate blood to the bodily organs. A stroke (not heart stroke) occurs when there is a blockage of one of the blood vessels supplying the brain or when a blood vessel in the brain leaks. ...Read more

Can you tell me the difference between heart failure from myocardial infarction?

Can you tell me the difference between heart failure from myocardial infarction?

Yes: Myocardial infarction ("heart attack") is permanent injury to heart muscle from lack of blood supply. Heart failure is a syndrome that can occur from many causes when the heart doesn't pump effectively. One of those causes can be myocardial infarction but CHF can also occur from high blood pressure, valve abnormalities, rhythm disturbances, infection, tumor, senescence and many, many other causes. ...Read more

Can you tell me the difference between a heart failure from myocardial infarction?

Can you tell me the difference between a heart failure from myocardial infarction?

HF and MI: Hf is due to ineffective pumping action of the heart resulting in fluid overload. Mi is due to blockage of one or several arteries that supply and nourish the heart. It might result in various complications. ...Read more

Heart Attack (Definition)

Heart attack is a life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
