I26-I28: Pulmonary heart disease and diseases of pulmonary circulation
I26: Pulmonary embolism
Pulmonary embolism (PE) is a serious condition that primarily affects the lungs and the cardiovascular system. It occurs when a blood clot, usually originating from the leg or pelvic veins, becomes dislodged and travels through the bloodstream to the lung, blocking a vessel. This blockage can restrict blood flow to the lung tissue, causing it to become starved of oxygen, which can lead to damage. Symptoms can vary widely, ranging from mild chest pain and breathlessness, to more severe symptoms like collapsing and heart failure, depending on the size and location of the embolism. PE can rapidly progress, potentially leading to sudden death if not promptly identified and managed. Common risk factors for PE include prolonged immobility, recent surgery or injury, certain medical conditions, and genetic predisposition.
