Flashcards

Left Heart Failure - Lung Symptoms

Left heart failure causes symptoms in the lungs due to the backflow of blood from the left ventricle to the left atrium and pulmonary veins. This backflow leads to pressure buildup in the lungs, resulting in shortness of breath and difficulty breathing when lying down (orthopnea).

LAP and PCWP Relationship

Left atrial pressure (LAP) is a measure of the pressure in the left atrium, and pulmonary capillary wedge pressure (PCWP) reflects the pressure in the pulmonary capillaries. Due to their close proximity, these pressures practically equal.

High PCWP Signifies

A high PCWP, indicating increased pressure in the lungs, is a sign of potential left heart pathology. It suggests the left ventricle is not effectively pumping blood forward.

PND and Left Heart Failure

Paroxysmal nocturnal dyspnea (PND) is a sudden shortness of breath that occurs at night, often waking the individual from sleep. It is a characteristic symptom of left heart failure.

Cardiogenic Shock Features

Cardiogenic shock is a life-threatening condition where the heart is unable to pump enough blood to meet the body's needs, leading to inadequate blood flow to vital organs. This condition is characterized by a low blood pressure (BP) and high PCWP, indicating left heart failure.

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.
