Cards

Term
Pleuirsy 
Definition
Thin membrane covering lungs surface (pleura) is irritated or inflamed.
Term
Pericarditis
Definition

Inflammation of the sac surrounding the heart. Worse when breathing deeply or lying down (better when sitting up or leaning forward). Chest pain may radiate to shoulders.

Prescribed NSAIDs with possible steroids if pain is not relieved within 48-96 hrs. Use of antibiotics are necessary if infection is present.

Term
Pericardital Effusion
Definition

complication of pericarditis when the space between the parietal and visceral layers fills with fluid. 

Diagnosed by X-ray, echo

Term
Cardiac Tamponade
Definition

Excessive fluid in the pericardial cavity. It restricts diastolic ventricular filling because the heart cannot expand, as a result, cardiac output drops. 

Diagnosed by ECG or X-ray. If not detected and it is a emergency, patient goes to cath. lab and the fluid needs to be removed (pericardiocentesis).

Term
Pulmonary Embolus
Definition

blockage of an artery in the lungs by fat,
air, a blood clot, or tumor cells.

Activity: bed rest, O2, modify living arrangements and ADL's

Medication: Anticoagulant therapy (heparin, warfarin), some fibrinolytic drugs (breaks down a fibrin clot- protein that is involved in the clotting of the blood).

Term
Pneumothorax
Definition

A collapsed lung is the collection of air in the
space around the lungs. This buildup of air puts pressure on the lung, so it cannot expand as much as it normally.

S/S: sudden, sharp pain on affected side (worse with breathing/coughing), dyspnea (shortness of breath), asymmetric chest wall movement.

Term
Dyspnea (Nursing Considerations)
Definition

Chest pain. 

Nursing Considerations: Stay with patient and assess while questioning. Assess pain (gradual/sudden, local/radiate, sharp/dull).

Term
Angina
Definition
Chest pain or discomfort due to ischemia (lack of O2 in the tissues).
Term
Severe Angina
Definition

Chest pain or discomfort that occurs at rest or with exertion and causes severe activity limitation. A increase in the number of attacks and intensity of the pain is what determines it unstable.

3 kinds: new-onset, varient (coronary artery spasm is a temporary, sudden narrowing of one of the coronary arteries), and pre-infarction.


Term
MI (myocardial infarction)
Definition

Coronary artery occlusion with death of the tissue. Occurs when the tissue is abruptly and severely deprived of O2. When blood flow decreases 80-90%, ischemia develops (lack of blood supply). Necrosis (tissue death) of myocardial tissue can occur if blood flow is not restored. 

Causes: -Atherosclerosis (plaque build up)

-Rupture of plaque

-Subsequent thrombosis (blood clot)

-Occlusion of blood flow

Term
Silent Ischemia
Definition

Lack of O2 without obvious pain but possible signs of decreased O2 sat, diaphoresis (excessive sweating), fatigue. 

Seen more in women, those with diabetes and those who cannot speak.

Term
Intra-aortic balloon pump
Definition
Used to decrease myocardial oxygen demand while at the same time increasing cardiac output. By increasing cardiac output it also increases coronary blood flow and therefore myocardial oxygen delivery. It consists of a cylindrical balloon that sits in the aorta and counterpulsates. That is, it actively deflates in systole increasing forward blood flow by reducing afterload thus, and actively inflates in diastole increasing blood flow to the coronary arteries.
