Coronary heart disease

• Plaque can be caused by high levels of cholesterol in the bloodstream.
• Coronary heart disease (CHD) occurs when there are blockages or narrowing of the coronary arteries due to plaque buildup.
• The coronary arteries supply blood to the myocardium, which is essential for its survival.
• Cholesterol is carried around the body in lipoproteins, which are made up of fatty acids (lipid) and proteins.
• HDL removes excess cholesterol from the body.
• The risk factors for CHD include smoking, obesity, lack of exercise, unhealthy diet, stress, diabetes, hypertension, and family history.
• LDL carries most of the cholesterol to cells that need it, but if there's too much LDL, excess cholesterol builds up on artery walls as plaque.
• When the coronary artery becomes blocked, it causes a lack of oxygenated blood reaching the myocardium, leading to damage and death of cardiac muscle cells.
• Symptoms of CHD may not appear until later stages, but they can include chest pain, shortness of breath, fatigue, dizziness, sweating, nausea/vomiting, and palpitations.
• LDL carries cholesterol to cells where it's needed but if too much LDL enters the walls of arteries, it causes damage.
• High blood pressure increases the risk of developing CHD as it puts extra strain on the heart and blood vessels.
• Atherosclerosis is the process where fatty deposits called plaques form on the inner walls of arteries, causing them to become hardened and less flexible over time.
• LDL carries more cholesterol than HDL.
• Smoking increases the likelihood of developing CHD as it damages the endothelium lining of the artery walls, making them more prone to damage.
• VLDL transports triglycerides to adipose tissue for storage as fat.
• HDL removes excess cholesterol from cells and transports it back to the liver where it is broken down.
• what is coronary heart disease?


  diseases that affect the blood vessels of the heart
• What is the build up in the blood vessels that can cause blockage?


  plague- furring of the arteries
• what can cause coronary disease?


  Smoking

  Stress

  Depression

  Obisity

  Poor diet

  Overconsumption of alcohol

  Lack of exercise
• What is the blockage of the plague made up off?


  cells of the immune system and cholesterol
• What is cholesterol ?


  A waxy, fat-like substance made in the liver, and found in the blood and in all cells of the body
• What are the purpose of the blood vessels?


  to supply deoxygenated blood to the heart-(right atrium)

  So it can contract(beat)
• What will the blockage cause?


  No oxygen to the heart causing any small or big part of the heart resulting in small or big heart attack
