Study Notes

Left Heart Failure

Left heart failure occurs when the left ventricle is unable to pump blood effectively.
This causes blood to back up into the lungs, leading to pulmonary congestion.
Symptoms often include shortness of breath, fatigue, and swelling in the legs and ankles.

Pulmonary Capillary Wedge Pressure (PCWP)

PCWP is a measure of pressure in the left ventricle.
It is often used to diagnose and monitor heart failure.
A high PCWP indicates increased pressure in the left ventricle and the pulmonary circulation.

PCWP and Left Atrial Pressure (LAP)

PCWP and LAP are closely related.
LAP is the pressure within the left atrium.
Typically, LAP is slightly lower than PCWP.

High PCWP and Low Blood Pressure

A high PCWP with a low blood pressure can signify a serious condition.
This combination suggests impaired left ventricle function, which can lead to decreased cardiac output and hypotension.
It is typically associated with congestive heart failure.
