Right heart failure (cor pulmonale)

Acute cor pulmonale is also called acute right-sided heart failure and acute RHF. It is the sudden failure of the right ventricle of the heart.

The right ventricle pumps blood out of the heart, into the pulmonary artery, and into the lungs. If the pulmonary artery is blocked, the right ventricle will quickly become overworked and in danger of shutting down. A blood clot, called an embolism, or plaque lining this artery can suddenly cut off blood flow from the heart into the lungs.

Risk factors for acute cor pulmonale include surgery, obesity, smoking, and prolonged immobility. All of these leave the person prone to blood clots and/or plaque in the arteries.

Symptoms include sudden chest pain with rapid heartbeat, pale skin, cold sweat, shortness of breath, and coughing, sometimes with blood.

Acute cor pulmonale is a life-threatening medical emergency. Take the patient to the emergency room or call 9-1-1.

Diagnosis is made through physical examination, blood tests, echocardiogram, and chest x-ray.

Treatment involves oxygen, diuretics, blood-thinning and clot-dissolving medications, and sometimes surgery.

Rarity: Common

Top Symptoms: fatigue, chest pain, shortness of breath on exertion, wheezing, decreased exercise tolerance

Symptoms that never occur with right heart failure (cor pulmonale): severe chest pain

Urgency: Hospital emergency room

Allergic reaction (not life-threatening)

When the body encounters a harmful substance, it responds with inflammation and swelling that can be protective. In many individuals, the body responds this way to substances that are not normally harmful, like foods or pollen. This is the basis of allergy, or Type 1 Hypersensitivity.

Rarity: Common

Top Symptoms: swollen face, swollen lips, lip numbness, hives, red swollen bumps or patches with a pale center, lip redness

Symptoms that never occur with allergic reaction (not life-threatening): shortness of breath, throat itching
