Objectives

Student will be able to identify and describe risk factors in relation to cardiovascular diseases.

Student will be able to display understanding of a heart attack, stroke, arrhythmia, congestive heart failure and stenosis.

Student will be able to apply knowledge of cardiovascular diseases through evaluating an individual’s lifestyle and measuring the likelihood of that person developing arteriosclerosis as a result.

Daily Recording Calendar What impacts your heart health? List some ways

that your can positively/negatively influence your heart health.

Did you know?

16 million Americans are living with heart disease Each year, nearly half a million die from it Commonly, a heart attack is the first sign of heart

disease

What is a cardiovascular disease?

#1 death globally Heart and blood vessel disease, also called heart

disease Includes many problems, many of which are

related to arteriosclerosis

What is arteriosclerosis?

“Hardening of the arteries” Causes many heart attacks, many strokes, and affects many other organs PLAQUE= Fatty buildup on arterial walls

What are the risks?

What are the risks for developing arterial disease? High blood pressure Cholesterol Cigarettes Diabetes Family history Low “good” cholesterol (HDL) High “bad” cholesterol (LDL)

What is a heart attack?

Blocked blood flow to heart, caused by blood clot If the clot cuts off blood flowcompletely, the part of the heart supplied by that artery begins to die

What is a stroke?

Cause: Cerebral Thrombosis:

A blood clot (thrombosis) in a cerebral artery or vein that supplies blood to the brain

“Brain attack”

What is a stroke?

How does it happen? Occurs when blood flow to a part of the brain

stops, caused by a blood clot If flow is stopped for longer than a couple seconds,

brain cannot get oxygen/blood Brain cells die, leading to possible permanent

brain damage

Stroke Risk Factors

High blood pressure Diabetes Family history High cholesterol Age Race Unhealthy Lifestyle

Types of Stroke

Ischemic Stroke: Occurs as a result of an obstruction within a blood vessel supplying blood to the brain

Hemorrhagic Stroke: Results from a weakened vessel that ruptures and bleeds into the surrounding brain

Congestive Heart Failure

Does heart failure mean the heart stops beating?

What is congestive heart failure?

“Can’t keep up” The heart is not pumping blood as well as it should Heart keeps working but body’s need for blood

and oxygen is not being met If not treated, can get worse

What is an arrhythmia?

“Abnormal rhythm” Heart can beat too fast, too slow or irregularly

Can affect how the heart works TOO SLOW=Bradycardia: Less than 60 beats per minute TOO FAST=Tachycardia: More than 100 beats per minute IRREGULAR= Atrial Fibrillation: Quivering

What is stenosis?

“Heart valve problems” Valves do not open enough to allow blood to flow through Regurgitation:

Heart valves do not close properly, allowing blood to leak through

Mitral Valve Prolapse: Valve not closed, allow blood to flow backwards into chamber

Treatment

Who is at risk for developing

arteriosclerosis? Framingham Heart Study: Risk Calculator With your group, read over the scenario you were given Calculate the person’s risk for developing

arteriosclerosis using the “risk calculator” To access risk calculator: Type ‘Framingham risk

calculator’ in Google. Click on the first link Record the risk percentage and answer the questions

that follow with your group Be ready to share your finding with the rest of the class
