Heart Attack SensorsPhan Viet AnhTrieu Van Vu QuanDao Duy TungPhD : Pham Nguyen Thanh Loan1ContentSome information about Heart AttackStructure of Heart attack sensorFunction to diagnose Heart attack and warning2Heart attack What is heart attack?It is a sudden interruption in the heart’s blood supply.If the heart muscle does not have enough blood ( with oxygen ), it dies and heart attack occurs. 3Heart attack What causes a heart attackAtherosclerosis: A gradual process by the collecting of cholesterol in the wall of arteryAngina : An illness where not enough oxygen is reaching heartAge, diabetes, diet, gene, heart surgery, smoking, etc 4In artery, plaque of cholesterol is hard on outside, sometime hard outer shell crack, then blood clots form around this and cut off the blood flow to the heart.5Heart attack Complication of heart attackHeart failure: when a large of heart muscle dies, the ability to pump blood to the body is decrease, then heart failure.Ventricular fibrillation: that cause the heart stop pumping blood, then die.6Heart attack Symptoms of heart attackPain and pressure of the chest, toothache, headache, sweating, shortness of breath, abdominal pain, etc..No symptoms: a quarter of all heart attack are silent, with out chest pain or another symptoms.
