What is a common sequelae of pulmonary embolism?

A common sequelae of pulmonary embolism is ischemia. When a pulmonary embolism occurs, it blocks blood flow to a portion of the lung. This obstruction can lead to reduced oxygen delivery to the affected area, resulting in ischemia. The lung tissues can become hypoxic, which may lead to complications such as decreased gas exchange and potential damage to lung tissue.

Conditions such as hypertension can develop as a result of chronic pulmonary embolism and may lead to pulmonary hypertension over time due to the strain placed on the right side of the heart. Fluid overload may be a concern in patients with heart failure but is not a direct sequela of pulmonary embolism. Similarly, hypercapnia, which refers to elevated levels of carbon dioxide in the blood, may occur due to hypoventilation or severe lung disease but is not a direct outcome of a pulmonary embolism itself.

In summary, ischemia arises directly from the obstruction of blood flow caused by the embolism, leading to decreased oxygen supply to lung tissue, which is why it is recognized as a common sequelae of pulmonary embolism.
