What term describes a type of blood pressure affecting the heart and lungs?

Pulmonary hypertension specifically refers to high blood pressure that occurs in the arteries of the lungs. This condition affects how blood moves through the lungs and can lead to a series of complications for both the heart and lungs. In pulmonary hypertension, the right side of the heart must work harder to pump blood through narrowed pulmonary arteries, which can ultimately lead to heart failure if left untreated.

Hypertension refers to high blood pressure in general and can affect the entire body, including systemic circulation, but it does not specifically target the blood vessels of the lungs. Hypotension relates to low blood pressure, and systemic hypertension, like general hypertension, does not isolate the pulmonary circulation. Thus, the most accurate term for a type of blood pressure that directly affects the heart and lungs is pulmonary hypertension.
