Transcript

  • 1. Preventing Major Disease• Define cardiometabolic health, and list actions for lowering cardiometabolic risk.• Explain the disease process of diabetes mellitus, and describe the early symptoms and treatment for this disease.• Define hypertension, and discuss why it is dangerous and ways to prevent it.• Describe the types of cholesterol that compose their lipoprotein profile and the effects of each on heart health.• Explain how the heart functions, and define a myocardial infarction.• Define stroke and transient ischemic attacks.• Discuss the most common types of cancer, and describe the treatments for each.• List their cardiometabolic and cancer risk factors. Chapter Learning Objectives
  • 2. Topics Of Focus For This Chapter Cardiometabolic Heart Attack Health Diabetes Stroke Hypertension Cancer Cholesterol Lifestyle

  • 4. Control Weight and Waist Circumference Overweight teens have high risk of diabetes and heart disease in future Weight Obese men have dramatically higher risk of dying Subcutaneous fat and visceral fat are dangerous Waist Avoid waists of: Size  40 inches for men  30 inches for women  Potbelly with normal weight
  • 5. Physical Activity Decreases Risk All Least fit are at greater risk of death More rigorous exercise = greater Men protection and longevity 30 minutes/day of moderate activity lessens risk Women Fitness more important than overweight or obesity in cardiometabolic risk
  • 6. Smoking Is The Most Significant Risk Factor Causes over 250,000 deaths per year • Causes peripheral arterial disease • Active and passive smoking  Accelerate artery clogging  Increase risk of developing coronary heart disease

  • 31. Heart Anatomy
  • 32. Heart Anatomy
  • 33. Overview Of Blood Flow Through Heart Right• Blood from Ventricle body moves Contracts • Blood moves into right atrium into right ventricle Right Atrium Contracts Left Ventricle • Blood moves Contracts to lungs and • Blood moves • Blood moves through aorta then pulmonary vein into left to brain and ventricle body Left Atrium Contracts
  • 34. How Blood Flows Through Body
  • 35. Understanding The Heart Myocardium Heart muscle 2-layer membrane surrounding heart Pericardium Lubricant between layers allows heart muscle to move freely Systole Contraction of heart Period between contractions when Diastole heart fills with blood Smallest blood vessels in body Capillaries Deliver oxygen via the blood and take up waste
  • 36. Cardiovascular Risk Factors Education Low education level at higher risk Chronic = plaque & high blood pressure Stress Episodic = creates unstable plaque Acute = trigger heart attack Depression and heart disease are linked Depression Depressed women more likely to have heart attack Anger Angry men at much higher risk
  • 37. Cardiovascular Risk Factors Continued C-Reactive protein signals inflammation CRP Increased CRP increases risk Homo- May influence atherosclerosis cysteine Sudden increases in blood pressure Illegal Left ventricular contraction Drugs Irregular heart rhythms Bacterial Streptococcus and chlamydia Infection

  • 41. Aspirin Is Recommended For Some Aspirin may reduce heart attack risk, but may also increase bleeding Aspirin decreases clotting risk, but increases • bleeding risk Must consider risk of gastrointestinal • bleeding when choosing to take aspirin • Men 45 to 79 to reduce risk of heart attack • Women 55-70 to reduce risk of stroke
  • 42. Heart Health Conditions Coronary Artery Disease Arteriosclerosis – degeneration and hardening of arterial walls Atherosclerosis – arteriosclerosis plus plaque deposits on walls of arteries
  • 43. Heart Conditions Angina Pectoris Due to brief lack of oxygen to heart Severe, suffocating chest pain Heart Attack / Myocardial Infarction When portion of heart does not receive oxygen and begins to die Cardiac Arrest Heart stops beating

  • 45. If experiencing heart attackIf experiencing heart attacksymptoms, take 325 mg of symptoms, take 325 mg ofaspirin and seek immediateaspirin and seek immediate medical attention medical attention
  • 46. Cardiac Arrest Cardio-pulmonary resuscitation CPR Combining rescue breaths with chest compressions creates circulation Automatic External Defibrillator AED Portable device available in most public places can restart a heart that has a lethal rhythm Control with diet, exercise and possibly Action medication
  • 47. Cerebrovascular Accident Explained ‘Stroke’ occurs when blood supply to Defined brain in blocked Ischemic – blockage of flow by cerebral Types thrombus or cerebral embolism Hemorrhagic – blood vessels rupture Transient Ischemic Attack TIA Little strokes with minimal damage Doubles risk of heart attack
  • 48. Cerebrovascular Accident Risk Women, especially during hormonal changes Men across the lifespan Heart disease and diabetes Risk Obesity and diet high in fat and sodium Factors Age – risk doubles every decade after 55 Race – high in blacks and Hispanics High red blood cell count High blood pressure
