  2. 2. INTRODUCTION• Cardiovascular disease is the every State’s leading killer for both men and women among all racial and ethnic groups.• A thorough cardiovascular assessment will help to identify significant factors that can influence cardiovascular health such as high blood cholesterol, cigarette use, diabetes, or hypertension.
  3. 3. TERMINOLOGY: • central venous pressure (CVP) It is the venous pressure as measured at the right atrium, done by means of a catheter introduced through the median cubital vein to the superior vena cava.
  4. 4. Blood pressure• It is the amount of force (pressure) that blood exerts on the walls of the blood vessels as it passes through them.
  5. 5. Systolic pressure • The blood pressure measured during the period of ventricular contraction (systole). In blood pressure readings, it is the higher of the two measurements
  6. 6. DIASTOLE:• The period between contractions of the atria or the ventricles during which blood enters the relaxed chambers from the systemic circulation and the lungs.
  7. 7. DIASTOLIC PRESSURE• The blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood.
  9. 9. History• The purpose of the cardiovascular health history is to provide information about your patient’s cardiovascular symptoms and how they developed. A complete cardiovascular history will give you indications to potential or underlying cardiovascular illnesses or disease states.
  10. 10. Past Health History• It is important to ask questions about your patient’s past health history. The past health history should elicit information about the following issues: hypertension, elevated blood cholesterol or triglycerides, heart murmurs, congenital heart disease, rheumatic fever or unexplained joint pains
  11. 11. Current Lifestyle andPsychosocial Status • Nutrition • Smoking • Alcohol • Exercise • Drugs • Family History
  12. 12. ASSESSMENT ARTICLES: • A Double-Headed, Double-Lumen Stethoscope • A Blood Pressure Cuff • A Moveable Light Source or Pen Light • Sphygmomanometer • Measure tap • Wrist watch and pen
  13. 13. INSPECTION:
  14. 14. Eyes• The presence of yellowish plaques on the eyelids (xanthelasma) could indicate hyperlipoproteinemia, a risk factor for hypertension as well as arteriolosclerosis.
  15. 15. Chest• Observe the chest for overall torso contour.• Do you see pectus excavatum (caved-in chest)?• Do you see pectus carinatum (pigeon chest)?
  16. 16. Skin • Clubbing The presence of clubbing (broadening of the extremities of the digits, accompanied by nails which are abnormally curved and shiny) indicates chronic poor oxygen perfusion to the distal tissues of the hand and feet.
  17. 17. Cyanosis • The presence of cyanosis (bluish colour) also denotes chronic poor oxygen delivery to the peripheral tissues of the hands and feet.
  18. 18. Xanthomas • The presence of yellowish plaques under the skin (non- eruptive) excoriated through the skin (eruptive) could indicate hyperlipoproteinemia, a risk factor for hypertension as well as arteriolosclerosis.
  19. 19. Edema• The presence of edema (tissue swelling) can be caused by several factors, although most commonly is associated with decreased cardiac function leading to decreased capillary flow.
  20. 20. Palpation • Use the palm of your hand to feel the chest wall for the "Point of Maximal Impulse" (PMI), which is usually found at the apex of the heart. This apical pulse is generally located in the 5th intercostal space, about 7-9 cm (the width of your palm) to the left of the midline.
  21. 21. • Palpate the peripheral arteries. These include the brachial, radial, femoral, popliteal, dorsalis pedis, and posterior tibial. Note the contour and amplitude of each pulsation. These should feel similar bilaterally.
  22. 22. Chest percussion:• Normally only the left border of heart can be detected by percussion. It extends from the sternum to mid clavicular line in the third to fifth inter costal space. The right border lies under the right margin of the sternum and is not detectable. Enlargement of the heart too either the left or right usually can be noted.
  23. 23. Auscultation:
  24. 24. S1 • S1, the “lub” of the “lub-dub,” is produced by the closure of tricuspid and mitral valves. • S1 is accentuated in exercise, anemia, hyperthyroidism, and mitral stenosis. • S1 is diminished in first degree heart block. • S1 split is most audible in tricuspid area (T-lub-dub)
  25. 25. S2• S2, the “dub” of the “lub-dub,” is produced by the closure of aortic & pulmonic valves.• Normal physiological splitting of S2 is best heard at pulmonic area. It occurs on inspiration(“lub-T-dub, lub-dub”).• Splitting of S2 can indicate pulmonic stenosis, atrial septal defect, right ventricular failure,• and left bundle branch block
  26. 26. S3 • S3 is also known as a ventricular gallop (“lub-DUB-ta”). S3 is heard in early diastole. It is normal in pregnancy, children, adults less than thirty years old, during exercise, anxiety, or anemia. • It is heard best at the apex in the left lateral decubitus position, using the bell. Pathologic S3 occurs in people over the age of 40, usually due to myocardial failure.
  27. 27. left lateral decubitus position
  28. 28. S4 • S4 is also known as an atrial gallop (“ta-lub-DUB”). It is typically heard in late diastole before S1. It results when ventricular resistance to atrial filling is increased from either decreased ventricular compliance or increased ventricular volume
  29. 29. Summation Gallop • A summation gallop is produced when S3 & S4 merge into one sound. It often occurs at rates greater than 100 beats per minute. It may occur in heart failure and pericarditis. Summation gallops occur in 15% of all myocardial infarctions
  30. 30. Opening Snap • At the end of ventricular systole, when the aortic and pulmonic valves close, S2 is produced Immediately after S2, the heart relaxes, and ventricular pressure falls below that of atrial pressure. This allows the atrioventricular valves to open. This is the start of diastole.
  31. 31. Ejection Click • Similar to an opening snap, an ejection click is caused by stenotic valve leaflets. This sound is produced when the aortic or pulmonic valves open at the beginning of systole. It is a brief high frequency sound best heard with the diaphragm over the aortic or pulmonary artery or Erb’s point, or near the apex over the mitral area
  32. 32. Mid-systolic Click • A mid-systolic click occurs when the mitral valve’s leaflets and cordae tendenae tense. The anterior or posterior or both leaflets can prolapse. Every once in a while multiple clicks occur. • They are heard in mid to late systole. They are best heard over the tricuspid area and towards the mitral area.
  33. 33. Pericardial Friction Rub • A pericardial friction rub is usually heard best and is sometimes palpable over the tricuspid and xyphoid areas. It occurs when inflamed pericardial surfaces rub together
  34. 34. Murmurs • A murmur is an abnormal heart sound caused by turbulent blood flow. The sound may indicate that blood is flowing through a damaged or overworked heart valve, that there may be a hole in one of the hearts walls, or that there is a narrowing in one of the hearts vessels
  35. 35. • Some heart murmurs are a harmless type called innocent heart murmurs which are common in children and usually do not require treatment
