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.
