Cardiovascular Diseases

  1. 1. Cardiovascular Diseases (Multifactorial Heart Diseases)
  2. 2. Types of Heart Diseases • There is a disease for almost every aspect of the heart.
  3. 3. We Will Be Looking At The Following: •Atherosclerosis •Coronary Heart Disease •Stroke
  4. 4. Atherosclerosis disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls.
  5. 5. Atherosclerosis Top-Up - Atherosclerosis can affect any artery in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. As a result, different diseases may develop based on which arteries are affected.
  6. 6. Coronary Heart Disease (CHD) • Plaque narrows the coronary arteries and reduces blood flow to your heart muscle. • Plaque buildup also makes it more likely that blood clots will form in your arteries. Blood clots can partially or completely block blood flow.
  7. 7. Coronary Heart Disease (CHD) • The disease process begins when LDL (“bad” cholesterol) deposits cholesterol in the artery wall. • A myocardial infarction (heart attack) occurs when the heart muscle tissue does not receive vital oxygen and nutrients.
  8. 8. Angina – Pectoris (CHD) • Angina is chest pain or discomfort that occurs when your heart doesn't get as much blood and oxygen as it needs. • There are two kinds of Angina; one where it is reversible and you can get rid of it, and the other, progressive.
  9. 9. Heart Failure(CHD) • Heart Failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood through the heart to meet the body's needs for blood and oxygen. • Heart failure usually results in an enlarged heart.
  10. 10. Heart Attack (CHD) • A Heart Attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or stopped. • This happens because coronary arteries that supply the heart with blood can slowly become thicker and harder from a buildup of fat, cholesterol and other substances, called plaque.
  11. 11. Stroke • A Stroke results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.
