What do we know about the cardiovascular system???
What have we learned about CVDs???
What are CVDs???
Composed of three Elements:
Normal Blood Flow is important
blood supply has transportation responsibilities
Types of CVDS
All CVDs disrupt normal blood flow in the body
Cardiovascular diseases have an array of symptoms that can affect people differently
Some CVDs may be silent or go undiagnosed until a patient has a heart attack, arrythmia, stroke, or goes into cardiac arrest
Loss of consciousness
Heart palpitations
Difficulty breathing
Chest pain
Is everyone living with the same risk of cardiovascular disease?
There are variables that can directly or indirectly influence the likelihood of getting a disease or injury.
Intrinsic Factor- are personal or "set" factors which increase or decrease the likelihood of an individual developing CVD.
Extrinsic Factors- are eternal or lifestyle variables that increase or decrease the possibility of developing CVD.
What can we do to slow down CVD?
What is a "healthy" weight?
There are MANY ways to determine a healthy weight for each individual & YOU know quite a few!

Exercise!!
What does exercising do?
When we exercise:
Blood pressure is the measure of arterial resistance that blood pumped from the heart must overcome in order to properly circulate
Physical activity leads to increase in heart strength due to the stress on the heart, leading to increased in blood output, more blood being ejected with each contraction, thus lowering blood pressure.
In sedendary populations:
A 10-20% positive change in Cholesterol levels can decrease CVD risk significantly
Why do we want a in LDL?
Why do we want an in HDL?
High Density Lipoprotein
Low Density Lipoprotein
Article:
• The preventive medical exam included obtaining height/weight and calculating BMI, Heart Rate, ECG, Blood chemistry test, Blood pressure, medical history, cigarette smoking history, and fitness level.
THE TEST
• The Relative risks (RRs) for low fitness were among the highest seen of all-cause mortality
• The third major finding was that moderate and high levels of cardiorespiratory fitness seem to provide protection against the force of combinations of other mortality predictors on deaths. fitness was inversely associated with death rates in persons who had no other predictors or had any 1 predictors. High-fit persons with multiple predictors had lower death rates than low-fit persons who had no other predictors
• 601 died during observation 226 due to CVD
• Found that all precursors highly correlated with CVD and all- cause mortality
• general pattern was that of a considerably lower death rate in moderately fit men compared with those in the low-fitness group all-cause death rates were from 17% to 39% lower in moderately fit men compared with low-fit men who smoked cigarettes, had elevated blood pressure
• 89 died 21 from CVD
• Elevated glucose and abnormal ECG were the primary precursors associated with CVD mortality however low fitness was close
• general pattern was that of a considerably lower death rate in moderately fit women compared with those in the low-fitness group all-cause death rates were from 48% to 67% lower in moderately fit women compared with low-fit women who smoked cigarettes, had elevated blood pressure
CONCLUSIONS
Overall Low fitness is an important precursor of mortality. Fitness has a protective factor for both smokers and nonsmokers, those with and without elevated cholesterol levels or elevated blood pressure, and unhealthy and healthy
persons. However there are even better RR's if non smoker and are in relative good health as well
