  1. Heart Failure Daniel E. van Buren, M.D. New England Heart Institute Androcsoggin Valley Hosptital

  2. How Many People HaveHeart Failure? • Heart failure is very common • It is the number one reason why people are admitted into hospitals in the U.S. • Heart failure effects nearly 5 million Americans • An estimated 400,000 to 700,000 new cases are diagnosed each year

  3. Heart Failure What is Heart Failure?

  4. Heart Failure Does NOT mean… • Your heart has stopped working • Your heart is about to stop working • You have had a heart attack

  5. Heart Failure • What is Heart Failure? • The heart is not pumping as well as it should • Usually, the heart has been weakened by an underlying condition • Blocked arteries • Heart attack • High blood pressure • Diabetes • Infections • Heart valve abnormalities

  6. Heart Failure • What is Heart Failure? • Heart failure can involve the left or right side of the heart or both • Usually the left side is affected first • Heart failure occurs when either side of the heart cannot keep up with the flow of blood

  7. Heart Failure • What is Left Heart Failure? • Involves the left ventricle (lower chamber) of the heart • Systolic failure • The heart looses it’s ability to contract or pump blood into the circulation • Diastolic failure • The heart looses it’s ability to relax because it becomes stiff • Heart cannot fill properly between each beat and less blood in means less blood out.

  8. Heart Failure • What is Left Heart Failure? • In both types, blood may “back up” in the lungs causing fluid to leak into the lungs (pulmonary edema) • Fluid may also build up in tissues throughout the body (edema)

  9. Heart Failure • What is Right Heart Failure? • Usually occurs as a result of left heart failure • The right ventricle pumps blood to the lungs for oxygen • Occasionally isolated right heart failure can occur due to lung disease or blood clots to the lung (pulmonary embolism)

  10. Heart Failure • How fast does heart failure develop? • Usually a chronic disease • The heart tries to compensate for the loss in pumping function by: • Developing more muscle mass • Enlarging • Pumping faster

  11. Heart Failure • What Causes Heart Failure? • Health conditions that either damage the heart or make it work too hard • Coronary artery disease • Heart attack • High blood pressure • Abnormal heart valves • Heart muscle diseases (cardiomyopathy) • Heart inflammation (myocarditis)

  12. Heart Failure • What Causes Heart Failure? • Congenital heart defects • Severe lung disease • Diabetes • Severe anemia • Overactive thyroid gland (hyperthyroidism) • Abnormal heart rhythms

  13. Heart Failure • What Causes Heart Failure? • Coronary artery disease • Cholesterol and fatty deposits build up in the heart’s arteries • Less blood and oxygen reach the heart muscle • This causes the heart to work harder and occasionally damages the heart muscle

  14. Heart Failure • What Causes Heart Failure? • Heart attack • An artery supplying blood to the heart becomes blocked • Loss of oxygen and nutrients damages heart muscle tissue causing it to die • Remaining healthy heart muscle must pump harder to keep up

  15. Heart Failure • What Causes Heart Failure? • High blood pressure • Uncontrolled high blood pressure doubles a persons risk of developing heart failure • Heart must pump harder to keep blood circulating • Over time, chamber first thickens, then gets larger and weaker

  16. Heart Failure • What Causes Heart Failure? • Abnormal heart valves • Heart muscle disease • Damage to heart muscle due to drugs, alcohol or infections • Congenital heart disease • Severe lung disease

  17. Heart Failure • What Causes Heart Failure? • Diabetes • Tend to have other conditions that make the heart work harder • Obesity • Hypertension • High cholesterol

  18. Heart Failure • What Causes Heart Failure? • Severe anemia • Not enough red blood cells to carry oxygen • Heart beats faster and can become overtaxed with the effort • Hyperthyroidism • Body metabolism is increased and overworks the heart • Abnormal Heart Rhythm • If the heart beats too fast, too slow or irregular it may not be able to pump enough blood to the body

  19. What Are The Symptoms of Heart Failure? • Think FACES… • Fatigue • Activities limited • Chest congestion • Edema • Shortness of breath

  20. Heart Failure • Signs and Symptoms of Heart Failure • Shortness of Breath (dyspnea) • WHY? • Blood “backs up” in the pulmonary veins because the heart can’t keep up with the supply an fluid leaks into the lungs • SYMPTOMS • Dyspnea on exertion or at rest • Difficulty breathing when lying flat • Waking up short of breath

  21. Heart Failure • Signs and Symptoms of Heart Failure • Persistent Cough or Wheezing • WHY? • Fluid “backs up” in the lungs • SYMPTOMS • Coughing that produces white or pink blood-tinged sputum

  22. Heart Failure • Signs and Symptoms of Heart Failure • Edema • WHY? • Decreased blood flow out of the weak heart • Blood returning to the heart from the veins “backs up” causing fluid to build up in tissues • SYMPTOMS • Swelling in feet, ankles, legs or abdomen • Weight gain

  23. Heart Failure • Signs and Symptoms of Heart Failure • Tiredness, fatigue • WHY? • Heart can’t pump enough blood to meet needs of bodies tissues • Body diverts blood away from less vital organs (muscles in limbs) and sends it to the heart and brain • SYMPTOMS • Constant tired feeling • Difficulty with everyday activities

  24. Heart Failure • Signs and Symptoms of Heart Failure • Lack of appetite/ Nausea • WHY? • Blood backs up causing swelling of the digestive tract • The digestive system receives less blood causing problems with digestion • SYMPTOMS • Feeling of being full or sick to your stomach

  25. Heart Failure • Signs and Symptoms of Heart Failure • Confusion/ Impaired thinking • WHY? • Changing levels of substances in the blood ( sodium) can cause confusion • SYMPTOMS • Cognitive slowing • Memory loss or feeling of disorientation • Relative or caregiver may notice this first

  26. Heart Failure • Signs and Symptoms of Heart Failure • Increased heart rate • WHY? • The heart beats faster to “make up for” the loss in pumping function • SYMPTOMS • Heart palpitations • May feel like the heart is racing or throbbing

  27. Your Doctor May Run These Tests… • Electrocardiogram (“EKG” or “ECG”) • Echocardiogram (“Echo”) • Chest x-ray • Cardiac Catheterization (“Cath”)

  28. What is Ejection Fraction (“EF”)?

  29. Heart Failure • Treatment Options • The more common forms of heart failure cannot be cured, but can be treated • Lifestyle changes • Medications • Surgery and device implantations

  30. Heart Failure • New York Heart Association (NYHA) Functional Classification

  31. Heart Failure • Lifestyle changes • Stop smoking • Loose weight • Avoid alcohol • Avoid or limit caffeine • Eat a low-fat, low-sodium diet • Exercise

  32. Heart Failure • Lifestyle changes • Reduce stress • Keep track of symptoms and weight and report any changes or concern to the doctor • Limit fluid intake • See the doctor more frequently

  33. Heart Failure • Medications used to treat Heart Failure • ACE Inhibitors • Cornerstone of heart failure therapy • Proven to slow the progression of heart failure • Vasodilator – cause blood vessels to expand lowering blood pressure and the hearts work load • Directly inhibit “remodeling” • Improves symptoms, reduces hospitalizations, slows progression of disease and reduces mortality

  34. Heart Failure • Medications used to treat Heart Failure • Beta-blockers • Lower the heart rate and blood pressure • Decrease the workload of the heart • Inhibit “remodeling” • Improves symptoms, reduces hospitalizations, slows progression of disease and reduces mortality

  35. Heart Failure • Medications used to treat Heart Failure • Aldosterone antagonists • Alters hormones that are damaging to the heart • Given for advanced heart failure • Inhibit “remodeling” • Improves symptoms, reduces hospitalizations, slows progression of disease and reduces mortality

  36. Heart Failure • Medications used to treat Heart Failure • Vasodilators • Cause blood vessel walls to relax • Occasionally used if patient cannot tolerate ACE inhibitors • Decrease workload of the heart

  37. Heart Failure • Medications used to treat Heart Failure • Diuretics (water pills) • Prescribed for fluid build up, swelling or edema • Cause kidneys to remove more sodium and water from the bloodstream • Decreases workload of the heart and edema • Fine balance – removing too much fluid can strain kidneys or cause low blood pressure • Improves symptoms and reduces hospitalizations

  38. Heart Failure • Medications used to treat Heart Failure • Digitalis preparations • Increases the force of the hearts contractions • Relieves symptoms • Slows heart rate and certain irregular heart beats • Improves symptoms and reduces hospitalizations

  39. Heart Failure • Medications used to treat Heart Failure • Potassium • Most diuretics remove potassium from the body • Potassium pills compensate for the amount lost in the urine • Potassium helps control heart rhythm and is essential for the normal work of the nervous system and muscles

  40. Heart Failure • Treatment options • Surgery and other Medical Procedures • Coronary artery bypass • Angioplasty • Valve replacement • Automated Implantable Cardioverter-Defibrillator (AICD) • Biventricular pacemaker (BiV or CRT) • Left ventricular assist device • Heart transplant

  41. AICD

  42. AICD Monitors heart rhythm Shocks to reset rhythm Can be interrogated Does not alter symptoms

  43. Biventricular Pacemaker Reserved for patients with symptoms despite optimal medical therapy Conduction disease Improves symptoms Reduces mortality

  44. Left Ventricular Assist Device
