Cardiovascular Disease (CVD) CVD affects the heart (cardio) and blood vessels (vascular).

Lifestyle Disease vs. Contagious Disease  What is the difference between a lifestyle disease & a contagious disease?  Give an example of each.  List two ways that a lifestyle disease be prevented?

Causes of Cardio Vascular Disease:  Heredity  Environment  High fat diets  Smoking  Lack of exercise  Stress  Obesity

Coronary arteries  Supply oxygen rich blood to the heart muscle

Diseases of the Arteries-Atherosclerosis ( ath·er·o·scle·ro·sis)  When plaque builds up in the arteries  Can result in blocking the blood flow to the arteries  Leads to coronary artery disease

Stroke  Obesity and smoking can lead to a buildup of deposits in your arteries that form a blood clot.  If the clot is close to your brain, it can block the flow of blood and oxygen and cause a stroke.

Diseases of the heart  Angina Pectoris-  A pain or tightness in the chest caused by lack of oxygen to the heart  Heart Attack-  The blood flow to a section of heart muscle becomes blocked. If the flow of blood isn’t restored quickly, the section of heart muscle becomes damaged from lack of oxygen and begins to die.  Congestive Heart failure-  Heart failure develops over time as the pumping of the heart grows weaker. Problems sending blood & oxygen around the body. Heart will increase in size.

Types of CVD-Hypertension  Blood pressure is the force of the blood pushing on the arteries.  High blood pressure makes the heart work harder and the strains the walls of the arteries.

Prevention  Avoid tobacco, alcohol & drugs  Eat a balanced diet  Maintain a healthy weight  Exercise  Manage stress
