Cardiac Compromise• Blanket term• Sometimes called Acute Coronary Syndrome
or ACS• Refers to a cardiac event of rapid onset• ACS {ischemia}
Cardiac Compromise can be caused by disorders that affect the condition and function of the heart:
• CAD• Aneurism• Electrical malfunctions• Mechanical malfunctins• Angina
• CHF• Thrombus• Embolism• AMI
CAD• Coronary Arteries• Narrowing or blockage• Blood flow reduced, impeding O2 to the heart• Under stress or exertion, Hear rate ↑s
increasing oxygen demand
The culprits:• ArteriosclerosisStiffening or hardening of the arterial wall from
Ca++ depositsElasticity is lost changing blood flow and ↑ng
B/P
• AtherosclerosisBuild up of fatty deposits on the inner walls of
the arteriesNarrowing of the diameter of the vessel
Aneurism• Angina PectorisLiterally means a pain in the chestCAD
CHF• Congestive Heart Failure• Inadequate pumping of the heart• Left sided heart failure• May be brought on by
Diseased heart valvesHTNCOPD
Resulting in• Edema
backup of fluids• Cardiogenic Shock
Signs and symptoms of CHF• Tachycardia• Dyspnea• Normal or ↑d B/P• Cyanosis• Diaphoresis• Cool / clammy / skin• Rales
• Anxiety• Confusion• Pedal edema• JVD {late sign}• ABD distension
Treatment Modalities• O2• POC
