LESSON 9 Flashcards
A condition in which ‘plaque builds up inside the coronary arteries’
Coronary Artery Disease
The arteries that supply the heart muscle with ‘oxygen rich blood’
Coronary artery
It is made up of fat, cholesterol, calcium, and other substance found in the blood
Plaque
It narrows the arteries and reduces blood flow to the heart muscle
Plaque
What is the classic symptom of coronary heart disease?
Angina
The pain caused by loss of oxygen and nutrients to the myocardial tissue’ because of inadequate coronary blood flow
Angina
It is sometimes grouped with MI under the diagnosis of acute coronary syndrome
Unstable Angina
The primary function of this system is ‘‘to deliver oxygen and nutrients to various tissues of the body”
Arterial system
Three cellular processes
Osmosis
Filtration
Diffusion
How many major coronary arteries?
3
It is most often form where the vessels branch, suggesting a hemodynamic component that favors their formation
Atherosclerotict lesions
The inner lining of the vessel wall
Endothelium
It normally nonreactive to platelets and leukocytes, as well as coagulation, fibronolytic, and complement factors
Endothelium
It is called chest pain
angina
It is also can be described as chest discomfort, heaviness, tightness, pressure, aching, pressure, aching, burning, etc.
angina
Angina can also be felt on what parts of the body (except chest)
left shoulder
arms
neck
back
jaw
Irregular heartbeats, skipped beats, or a ‘‘flip flop’’ feeling in your chest
Heart palpitations
It is a sign of ischemia
St depression
Sign of injury to muscle
St elevation
Give samples for the blood chemistry for a patient with CAD
Increased total cholesterol
Decreased HDL
Increased LDL
T-wave inversion
ST depression
Major risk factors of CAD / Modifiable factors
Cholesterol abnormalities
Diabetes Mellitus
Hypertension
Tobacco use
This classification of drugs is ‘‘used to reduce workload of heart”
beta-adrenergic blockers
Example of beta-adrenergic blockers
metoprolol
propanorol
nadolol
This classification of drugs is used to ‘‘reduce heart rate, bp, and muscle contractility.
calcium channel blockers
