Sometimes, a blood clot forms in one of these narrowed arteries. A slow narrowing of the coronary arteries can weaken the left ventricle. Over time, the arteries that supply blood to the heart muscle can become narrow from fatty deposits (plaques). Medical conditions that can cause heart failure and lead to pulmonary edema include:Ĭoronary artery disease. The increased pressure pushes fluid through the blood vessel walls into the air sacs. When a diseased or overworked left lower heart chamber (left ventricle) can't pump out enough of the blood it gets from the lungs, pressures in the heart go up. Heart-related (cardiogenic) pulmonary edemaĬardiogenic pulmonary edema is caused by increased pressures in the heart. From the aorta, the blood travels to the rest of the body. The aortic valve keeps the blood from flowing backward into the heart. The heart valves keep blood flowing in the right direction. Finally, it leaves the heart through the body's main artery (aorta). It then flows through the mitral valve into the left ventricle. The oxygen-rich blood then returns to the left atrium through the pulmonary veins. There, the blood releases carbon dioxide and picks up oxygen as it flows by the alveoli. From there it's pumped through large blood vessels (pulmonary arteries) to the lungs. Typically, blood without oxygen from all over the body enters the right atrium then the right ventricle. The lower chambers pump blood out of the heart. The upper chambers (the right and left atria) receive incoming blood and pump it into the lower chambers (right and left ventricles). The typical heart is made of two upper and two lower chambers. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The upper chambers, the right and left atria, receive incoming blood. Instead, call 911 or emergency medical care and wait for help.Ī typical heart has two upper and two lower chambers. A sudden worsening of any of pulmonary edema symptomsĭon't drive yourself to the hospital.A big drop in blood pressure that causes lightheadedness, dizziness, weakness or sweating.Breathing difficulty with a lot of sweating.Coughing up phlegm that looks pink or has blood in it.A bubbly, wheezing or gasping sound when breathing.Trouble breathing or a feeling of suffocating (dyspnea).Shortness of breath, especially if it comes on suddenly.Call 911 or emergency medical help if you have any of the following acute symptoms: Pulmonary edema that comes on suddenly (acute pulmonary edema) is life-threatening. Symptoms of high-altitude pulmonary edema (HAPE) tend to get worse at night. Later, a cough that produces frothy sputum that may look pink or have blood in it.Not being able to exercise as much as you once could.Shortness of breath with activity, which becomes shortness of breath at rest.Headache, which may be the first symptom.Symptoms are similar to those that occur with acute pulmonary edema and can include: HAPE can occur in adults and children who travel to or exercise at high altitudes. High-altitude pulmonary edema (HAPE) signs and symptoms More shortness of breath than usual when you're physically active.Difficulty breathing with activity or when lying flat.Awakening at night with a cough or breathless feeling that may be relieved by sitting up.Long-term (chronic) pulmonary edema signs and symptoms

Anxiety, restlessness or a feeling that something bad is about to happen.A rapid, irregular heartbeat (palpitations).A cough that produces frothy sputum that may have blood in it.A feeling of suffocating or drowning that worsens when lying down.Difficulty breathing (dyspnea) or extreme shortness of breath that worsens with activity or when lying down.Symptoms depend on the type of pulmonary edema. Pulmonary edema symptoms may appear suddenly or develop over time.
