SIGNS AND
SYMPTOMS
PREDISPOSING FACTORS
Age: 74 years old
Build-up of plaque in the
coronary artery
Rupture of plaques without
complete arterial occlusion
(pre-infarction angina)
Subsequent Thrombus
Formation
Obstruction / occlusion in
the arteries
Decreased oxygen supply
to the coronary artery
Increased cardiac demand
for oxygen
Imbalance between
myocardial oxygen supply
and demand
Anaerobic Respiration
Cardiac Muscle Tissues are
Deprived of Oxygen
Decreased Cardiac
Function with
Compensatory Mechanism
Decreased Ejection
Fraction of the Left
Ventricle
Decreased total blood
circulation in the body
Decreasing blood
pressure
Progressive Weakness
Loss of consciousness
Cyanosis
Cool Skin
Shortness of breath
Cellular Injury Occurs
Thready Pulse
Ventricular Tachycardia
Hypotension
Lactic Acid Production
Subsequent Cellular
Necrosis (Infarction) of the
affected part of the Heart
Chest Pain, Weakness
Pooling and backing up of
blood in the legs, ankles,
and feet
