Quitting smoking, a healthy diet and exercise may reduce your risk of heart disease Plaque in coronary artery Circulatory System Disorders Heart Disease • Risk factors • Older age • Male gender • Cigarette smoking • High cholesterol • Diabetes • Stress • Obesity • Heredity • Physical inactivity • High blood pressure
Circulatory System Disorders Atherosclerosis • Starts with damage or injury to the inner layer of an artery • Fatty deposits called plaquebuild up in the arteries • This causes: • Blockage in artery • Less flexible vessels • High BloodPressure
Circulatory System Disorders Hypertension • High Blood Pressure Makes the heart and blood vessels work harder Increases the chance of heart disease, heart attack or stroke
Circulatory System Disorders Heart Attack • acute myocardial infarction • Interruption of oxygen supply to the heart • Causes death of the heart muscle • Leading cause of death in both men and women Coronary Blockage
Symptoms Chest pain Squeezing or heavy pressure on chest Pain that radiates down left shoulder and arm Shortness of breath Nausea or vomiting Anxiety or Fainting Lightheadedness - dizziness Palpitations (feeling like your heart is beating too fast) Sweating, which may be extreme Circulatory System Disorders Heart Attack
Circulatory System Disorders Stroke • Interruption of oxygen supply to the brain • Caused by: • A clot in an artery in the brain • Breakage of an artery in the brain • Causes brain cells to be deprivedof oxygen and die
Thrombotic strokeblood clot in cerebral artery Hemorrhagic strokeblood vessel ruptures
Embolism occurs when an object (usually a blood clot) migrates from one part of the body (through circulation) and causes a blockage (occlusion) of a blood vessel in another part of the body Thrombosis is the formation of a clot (thrombus) inside a blood vessel, obstructing the flow of blood Circulatory System Disorders Thrombosis/Embolism
Angioplasty • Opens clogged arteries, like Roto Rooter • Video
