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
