Cardiovascular Disorders
Hypertension p671
• Ateriosclerosis
• “silent killer”
• Heart muscle can
die due to lack of
Oxygen
• Increases
chances of CVA:
cerebral vascular
accident
Coronary Artery Disease
• Accumulation of
plaque buildup on
walls of arteries.
• arteriosclerosis
Heart Attack
• Mycardial infarction
• Caused by an
obstructured vessel in
heart thrombus, embolus
• deprivation of oxygen
(normally…body releases
hypoxia induced factor
which stimulates
angiogenesis)
• If angiogenesis isn’t
successful…part of heart
dies

Pericarditis
• Inflammation of
pericardial sac due to
viral or bacterial
infection
• Chest pain, interferes
with heart movements
Mitral Valve Prolapse
• One or both cusps of mitral
valve stretches and bulges into
left atrium during ventricular
contraction
• Blood can regurgitate into the
left atrium
• Palpitations, fatigue, anxiety,
chest pains
• associated with arrhythmias
(atrial fibrillation) that may
progress
Familial Amyloidosis
• Amyloid protein deposits into heart
• Causes chest pain, failure of
cardiac muscles, disturbance of
heart rhythm
• the deposits physically disrupt
tissue architecture; some cases
lead to cell death
• WHY? calcium ion concentration
imbalances
• Ultrasound: echocardiogram can
detect
Transposition of Great Arteries
