A 60 year old woman who experienced myocardial infarction (aka heart attack)
Background
Anatomy of the heart
Antrioventricular Valves
separate the mitral valve on left side and tricuspid valve on the right side
Semilunar Valves
Separate the ventricles from the large arteries coming off of them and the pulmonary valve on the right side
Mitral valve
on left side of the heart dividing left atrium and left ventricle
bicuspid valve
Septum
In between the ventricles
4 chambers
left atrium
right atrium
left ventricle
right ventricle
Chordea Tendineae
strong thick tissues attached to the valves
Aorta
Superior Vena Cava
Inferior vena cave
posterior to the heart below the superior vena cava
Myocardium
heart muscle to help push blood
Pathway of blood through the heart
Pacemakers cells generate electrical signals and myocytes contract as a group
Right Atrium & right ventricle
blood moves into your right ventricle
which contracts and sends blood out of your heart to your lungs
Lungs
gather oxygen
get rid of carbon dioxide
Left Atrium and Right Ventricle
Valves and Papillary of heart functions
Normal heart sounds & causes
Sound 1: caused by the atrioventricular valves at the beginning of systole
S2: caused by aortic pulmonary valves closing at the beginning of diastole
Relationship between heart function and blood pressure
Relationship between heart function and respiratory
Concepts: heart rate, stroke volume, cardiac output, mean arterial pressure, preload afterload, peripheral resistance and others revelant to this case
Respiratory System
Shortness of breath
pulmonary edema
Nervous Systems
lack of blood supply causes loss of gray matter
decline in mental processes
increasing stroke volume
urinary System
decreased renal and urine output
Mitral Valve fail
Abnormal heart sounds
back flow to the left ventricle
death
Direct Factors
Diabetes
Smoking
Alcohol intake
poor diet
hypertensions
No exercise
Stress
Indirect Factors
Family History
Age
Gender
