Cardio 3 Flashcards
Failure of the Heart to Pump Adequately, thereby reducing CO & compromising tissue perfusion.
Necrosis of more than 40% of L-Ventricle (result of occlusion of major coronary vessels).
Cardiogenic Shock
Maintain Tissue Oxygenation & Perfusion & Improve Pumping ability of the heart.
Cardiogenic Shock
Acute or chronic inflammation of pericardium.
Pericarditis
Constricts the Heart, Causing Compression.
Pericardial sac becomes inflamed.
Chronic Pericarditis (chronic inflammatory thickening of pericardium)
can result in loss of pericardial elasticity or an accumulation of fluid within the sac.
HF or Cardiac Tamponade may result.
Pericarditis.
Acute or Chronic Inflammation of Myocardium as result of Pericarditis, Systemic Infection, or Allergic Response.
Myocarditis
Inflammation of the Inner lining of the Heart & Valves
Endocarditis
occurs primarily in:
IV drug abusers,
Valve Replacements or Repairs w/ Prosthetic Materials,
Other Structural Cardiac defects.
Endocarditis
Oral Cavity (dental procedures),
Infections (cutaneous, genitourinary, GI, systemic),
Surgery or Invasive Procedures including IV placement.
Ports of entry for infecting organism: Endocarditis
occurs when space between Parietal & Visceral layers of Pericardium fills w/ fluid.
pericardial effusion (risk for Cardiac Tamponade)
accumulation of Fluid in pericardial cavity
Cardiac Tamponade
restricts Ventricular filling & CO drops
Cardiac Tamponade
can occur when small volumes (20-50 mL) of fluid accumulate rapidly in Pericardium
Acute Cardiac Tamponade
Occurs when Heart Valves cannot fully open (stenosis) or Close Completely (insufficiency / regurgitation).
Prevents efficient blood flow through the heart
Valvular Heart Disease
Valvular tissue Thickens & Narrows the valve Opening, Preventing Blood from Flowing from the Left Atrium to Left Ventricle
Mitral Stenosis
