Heart related disorders

  1. 1. Your heart muscle is the strongest and toughest muscle in the body.
  2. 2. Index Introduction about heart. Fact file The heart. Different types of heart disorders.
  3. 3. What is heart  The heart is the organ that supplies blood and oxygen to all parts of the body. It is about the size of a clenched fist, weighs about 10.5 ounces and is shaped like a cone. The heart is located in the chest cavity just posterior to the breastbone, between the lungs and superior to the diaphragm. The heart is surrounded by a fluid
  4. 4. What is heart disorder Heart disorder is nothing but heart disease. Heart disease is an umbrella term for any type of disorder that affects the heart. Heart disease means the same as cardiac disease. According to WHO (World Health Organization), heart disease is the leading cause of death in the UK, USA, Canada and
  5. 5. Fact file  Blood pressure is measured by using an instrument called sphygmomanometer. the study of the human heart and its various disorders is known as cardiology.  Depending on your body size, your body contains about 4 to 5 liters of blood.  The heart beats about 100,000 times a day.
  6. 6. The heart  Pulmonary artery  Pulmonary vein  Valves  Right ventricle  Right auricle  Aorta
  7. 7.  Pulmonary artery It takes blood to the lungs for oxygenation  Pulmonary vein It brings back oxygen rich blood from the lungs and pours into the left ventricle. Valves They separate each of the chamber so there is no mixing of blood. They allow blood to flow only in one direction. Right ventricle It pumps blood into the pulmonary artery that
  8. 8. Right auricle It gets blood from all parts of the body through veins. This blood is pumped into the right ventricle.  Aorta It carries blood to different parts of the body.  Left auricle It has thinner walls. It pumps blood into the left ventricle.  Left ventricle It has thicker
  9. 9. Types of heart disorders  Heart disease, or cardiovascular disease, is a general name for a wide variety of diseases, disorders and conditions that affect the heart and blood vessels. Heart disease is the number one cause of death in the United States, according to the Centers for Disease Control and Prevention. Heart diseases can

  11. 11. Coronary artery diseaseWhat is coronary artery disease?  Heart disease is a result of plaque buildup in your coronary arteries -- a condition called atherosclerosis -- that leads to blockages. The arteries, which start out smooth and elastic, become narrow and rigid, restricting blood flow to the heart. The heart becomes starved of oxygen and the vital
  12. 12. How Does Coronary Artery Disease Develop?  From a young age, cholesterol- laden plaque can start to deposit in the blood vessel walls. As you get older, the plaque burden builds up, inflaming the blood vessel walls and raising the risk of blood clots and heart attack. The plaques release chemicals that promote the process of healing but make the
  13. 13. William Harvey William Harvey was born in Kent in 1578. He was in first to propose in 1628 the complete theory of the circulation of blood, believing
  14. 14. Hypertension What is hypertension disease?When blood exerts too much pressure on the walls of blood vessels, it's called hypertension, or high blood pressure. The cause of hypertension is unknown for 90 to 95 percent of cases — this is called essential or
  15. 15. How does hypertension disease develop?  Hypertension occurs when the pressure inside the blood vessels is too high. When your heart pumps, it sends blood out through the arteries. The force of your blood pushing against the walls of your arteries causes pressure. Every time your heart beats, it forces more blood into the arteries, causing the pressure to
  16. 16. Restrictive cardiomyopathy What is Restrictive cardiomyopathy? Restrictive cardiomyopathy (RCM) is a rare disease of the myocardium and is the least common of the 3 clinically recognized and described cardiomyopathies. Its principal abnormality is diastolic
  17. 17. How does Restrictive cardiomyopathy develop? Restrictive cardiomyopathy is a disorder of the heart muscle in which the walls of the ventricles become stiff, but not necessarily thickened, so they resist normal filling with blood. There is no cure. Treatment aims to relieve symptoms caused by the backup of blood into the lungs and veins of
  18. 18. Alcoholic heart disease What is Alcoholic heart disease? Alcoholic heart disease is caused by a lifestyle in which alcoholics are continue to consume an excessive amount of alcohol over a long period of time. Total abstinence is a very effective way to treat them

  20. 20. Heart attack What is Heart attack? If the heart muscle does not have enough blood (and consequently oxygen) it dies and a heart attack occurs. Another name for a heart attack is myocardial infarction, cardiac infarction and coronary thrombosis. According to Med
  21. 21. How does a heart attack develop? A heart attack occurs when some part of the heart muscle stops getting blood and oxygen. This is usually caused by a clog in one or more of the arteries that carry blood and oxygen to the heart, as a result of coronary artery disease. The arteries become choked with fatty deposits called plaque over the course of many years. This process is called atherosclerosis. The buildup of fatty deposits, including cholesterol and other lipids, gradually narrows the artery, allowing

  23. 23. Heart failure What is heart failure? Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. In some cases, the heart can't fill with enough blood. In other cases, the heart can't pump blood to the rest of the body with enough force. Some people
  24. 24.  Heart failure (HF) is a condition that occurs when the heart cannot pump or fill with enough blood, which means that the heart must work harder to deliver blood to the body. The term "heart failure" is misleading because the heart does not completely fail or stop. Heart failure can be mild and cause minor symptoms, or it may be severe or even life-threatening. The most common symptoms of heart failure are How does heart failure develop?
  25. 25. Heart valve disease What is heart valve disease? Heart valve disease is a condition in which one or more of the four heart valves (tricuspid, pulmonary, mitral, and aortic) don't work properly. Heart valves can have three basic kinds of
  26. 26. How does heart valve disease develop?  Heart valve disease is a condition in which one or more of the valves in your heart aren't opening or closing the way they should, disrupting blood flow into and out of the heart. There are several types of heart valve disease, but the two main types associated with heart
  27. 27. Heart muscle disease What is Heart muscle disease? Heart muscle disease, also known as cardiomyopathy, may be congenital or acquired, and refers to a heart that is abnormally
  28. 28. How does heart muscle disease? Cardiomyopathy refers to heart muscle disease. The damaged heart does not effectively pump blood. The disease usually progresses to the point where patients develop life- threatening heart failure. In addition, people with cardiomyopathy are more likely to have irregular heartbeats orarrhythmias.There are two major categories of cardiomyopathy: ischemic and non- ischemic cardiomyopathy. Ischemic
