What Is a Pulmonary Embolism? Catherine O'Hara's Cause of Death Exposed

A pulmonary embolism, commonly known as PE, is a severe and life-threatening medical condition that happens when a blood clot obstructs an artery in the lungs, thereby interrupting blood circulation and lowering oxygen levels throughout the body.

The health problem became the main factor in the death of a famous actressCatherine O'Hara.

As per Harvard, the majority of pulmonary embolisms begin as deep vein thrombosis, or DVT, which is a clot that develops in a deep vein, typically in the legs or pelvis. When a portion of this clot detaches, it can move through the blood and become stuck in the lungs, thereby blocking blood flow. In uncommon instances, obstructions might result from fat, air, or cancer cells.

Pulmonary embolism symptoms

Symptoms may develop quickly and differ in intensity. The primary indicator is difficulty breathing, typically with sharp chest pain that can become more severe when taking a deep breath. Certain individuals might experience coughing up blood or mucus mixed with blood. Additional signs can involve an increased heart rate, feeling dizzy, experiencing lightheadedness, or even passing out.

Medical professionals warn that pulmonary embolisms are especially hazardous as they quickly stress the heart and hinder oxygen from reaching essential organs. If not treated promptly, a significant or neglected PE may result in lasting lung injury or fatalities.

Contributing factors consist of extended periods of inactivity, like being confined to bed or taking long trips, previous surgical procedures, cancer diagnosis, pregnancy, tobacco use, excess weight, and genetic conditions that increase the likelihood of blood clots. Individuals who have had blood clots in the past are also more susceptible.

Pulmonary embolisms are usually identified through imaging techniques like CT pulmonary angiography or specific lung scans. The treatment approach varies based on the size of the clot and the patient's overall health, but often involves anticoagulant medications, also referred to as blood thinners, to stop additional clots from forming. For more serious situations, physicians might administer clot-busting drugs or conduct procedures to eliminate the clot.

Public health authorities highlight that pulmonary embolism ranks among the top causes of cardiovascular fatalities in the U.S. and underline the significance of prompt identification and intervention. Individuals encountering abrupt difficulty breathing, chest discomfort, or unexpected dizziness are advised to immediately contact emergency services.
