is pulmonary edema heart failure?
126954
Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs.

The symptoms of end-stage congestive heart failure include dyspnea, chronic cough or wheezing, edema, nausea or lack of appetite, a high heart rate, and confusion or impaired thinking.

Pulmonary edema can develop after a blockage in the upper airway causes negative pressure in the lungs from intense efforts to breathe despite the blockage. Pulmonary embolism. Pulmonary embolism, a condition that occurs when blood clots travel from blood vessels in your legs to your lungs, can lead to pulmonary edema.

High blood pressure (hypertension). Other conditions may lead to cardiogenic pulmonary edema, such as high blood pressure due to narrowed kidney arteries (renal artery stenosis) and fluid buildup due to kidney disease or heart problems.

Edema is usually caused by excess tissue fluid that had not yet returned to the circulatory system. Lymphedema is swelling caused by excess protein-rich lymph trapped within the tissues.

Coughing. Breathing heavily. Swelling in the legs (most often seen with right-sided heart failure) A bloated, fluid-filled abdomen (most often seen with right-sided heart failure and also known as ascites)

Tests that may be done to diagnose pulmonary edema or to determine why you developed fluid in your lungs include: Chest X-ray. A chest X-ray will likely be the first test you have done to confirm the diagnosis of pulmonary edema and exclude other possible causes of your shortness of breath. Pulse oximetry.

Difficulty concentrating or decreased alertness. Sudden, severe shortness of breath and coughing up pink, foamy mucus. Chest pain if your heart failure is caused by a heart attack.

Diastolic heart failure occurs when the heart pumps normally, but the ventricles become stiff and doesn't relax properly. This causes the pressure to rise in the heart and lungs. Systolic heart failure occurs when the heart is weak and doesn't contract with enough force.

The major difference being that pneumonia is an infectious pathology while pulmonary edema is not usually caused by an infection. It is a marker for a more severe underlying systemic pathology like heart failure or volume overload states in the body.

Pulmonary edema is a condition in which the lungs fill with fluid. It's also known as lung congestion, lung water, and pulmonary congestion. When pulmonary edema occurs, the body struggles to get enough oxygen and you start to have shortness of breath.

["Fatigue. Fatigue is extreme tiredness that isn't necessarily caused by exertion or relieved by rest. ... ", 'Breathlessness. Breathlessness is a very common symptom of heart failure and it can be very limiting and distressing. ... ', 'Peripheral oedema.']

So GTN increases NO levels, increasing vessel dilatation. The main action in pulmonary oedema is to dilate capacitance vessels in the legs, reducing pre-load; there is also an effect on after-load. Although the stroke volume is unchanged, the myocardial workload, and hence oxygen consumption, is reduced.

Heart-related lung problems. Chest X-rays can show changes or problems in your lungs that stem from heart problems. For instance, fluid in your lungs can be a result of congestive heart failure.

Features that are helpful in distinguishing CHF from ARDS include the following: While cardiogenic pulmonary edema typically begins centrally in the bilateral perihilar areas, ARDS usually causes more uniform opacification. Pleural effusions are not typical of ARDS but often present in CHF.

Kidney failure and inability to excrete fluid from the body can cause fluid build-up in the blood vessels, resulting in pulmonary edema. In people with advanced kidney disease, dialysis may be necessary to remove the excess body fluid.

The most common clinical sign of congestive heart failure (CHF) is persistent coughing accompanied by difficulty breathing. This is due mainly to pulmonary edema or the accumulation of fluid in the lungs. The enlarged heart will also push against the trachea, causing irritation that can induce a cough.
