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

What is pathophysiologic of right sided heart failure !?

Right heart failure: The commonest cause of right heart failure is left heart failure. The causes of isolated right heart failure include primary pulmonary hypertension and pulmonary diseases associated with pulmonary hypertension. Left to right cardiac shunts cause right heart failure and mitral stenosis is another(techinically this is a left heart cause. ...Read more

Describe the difference between left heart failure and right heart failure?

Describe the difference between left heart failure and right heart failure?

Physical exam: Fluid accumulates during congestive heart failure. When the right side of the heart fails, fluid accumulates in the legs and abdomen. When the left side of the heart fails, fluid accumulates in the lungs and makes the patient short of breath. Not infrequently, both sides of the heart fail at the same time. ...Read more

What's the difference between congestive heart failure and right heart failure?

Similar: Congestive heart failure refers to the congestion (fluid buildup) which is seen in the lungs and the legs (swelling) and in the abdomen. (might be swollen). Heart failure can involve both the right and left sides of the heart depending on the exact cause. The most common cause of right heart failure is left heart failure but certain things such as lung disease can cause just right heart failure. ...Read more

What are the symptoms of left sided heart failure?

What are the symptoms of left sided heart failure?

Swelling: The left side of the heart pumps blood throughout your body. When it fails, it decreases blood flow to organs. This can cause kidney injury, liver injury, fatigue, shortness of breath with little exertion, swelling of the feet and legs, fluid build-up in the lungs, and difficulty sleeping flat due to shortness of breath. Medications and diet are important for this disease! ...Read more

How are the symptoms of right sided heart failure different from left heart?

How are the symptoms of right sided heart failure different from left heart?

Findings: One must remeber that the most common cause of right heart failure is left heart failure and thuswhat is often referred to as left heart failure can represent biventricular failure. Isolated left heart failure usually manifests in pulmonary edema and shortness of breath. Right heart failure can manifest as passive liver congestion, periphera edema, elevated venous jugluar pressures, etc. ...Read more

What are the signs and symptoms of left sided heart failure due associated with decreased cardiac output?

Congestion: Breathlessness, especially with exertion. Easy fatigability. Impaired exercise capacity. These are early signs. Without treatment, one becomes short of breath resting, especially when lying down (orthopnea) and at night (paroxysmal nocturnal dyspnea). Eventually the right heart also fails leading to swelling (edema), abdominal fluid (ascites and effusions), and cachexia (wasting). ...Read more

What causes heart failure?

What causes heart failure?

Heart failure: In a healthy heart, during each heartbeat a set amount of blood enters the heart and is pumped out again. In heart failure, your heart cannot cope with pumping the full amount of blood in each heartbeat. Systolic heart failure- the ventricles of the heart do not contract properly during each heartbeat so blood is not adequately pumped out of the heart.Diastolic heart failure. This occurs when the ventricle does not fill up with blood enough ...Read more

What are the symptoms of left sided heart failure due to your heart's low output?

Variable: These can vary tremendously from person to person. The symptoms can include fatigue, weakness, decreased exercise tolerance, shortness of breath, pulmonary edema. It can be associated with abnormal heart rhythms and also with symptoms of right heart failure as well (and commonly right heart failure symptoms do co-exist). ...Read more

What's the difference between left heart failure vs right heart failure?

R/L heart failure: Right heart (right ventricle and atrium) failure typically has dependent edema, liver enlargement and increased jugular venous pulsations. Left heart (left ventricle and atrium) failure typically manifests with pulmonary edema. You can even have a combination of the two. This classification is not used as much. We have a systolic, a diastolic and mixed heart failure- this is the most used. ...Read more

What are the causes of heart failure?

Depends: Congestive heart failure or CHF can be from many things. Different types include systolic dysfxn wich means a weak heart. Usually from a virus, heart attack, or post partum.Diastolic dysfxn where the heart is stiff is usually due to hyer tension. High out put heart failure is when things such as hyperthyroidism or anemia . So your question is very broad and you need to narrow it down ...Read more

What is the difference between left heart failure and right heart failure?

Left and right heart: Left heart failure reduces the ability of the heart to pump bold to the body. It is mainly caused by chronic hypertension, coronary artery disease or valve disease. It causes fliuid to build up in lungs. Right heart failure is the inability to pump blood to the lungs. It is mainly caused by lung disease or by pressure in lungs from left heart failure. Fluid then builds up in the bodies veins. ...Read more
