  2. OBJECTIVES • Identify pertinent findings from the history and physical examination that would contribute to the diagnosis of peripartumcardiomyopathy • Provide a systematic approach in diagnosing patients with peripartumcardiomyopathy • Determine supportive diagnostic examinations • Arrive at a definitive diagnosis • Learn how to conservatively manage patients with peripartumcardiomyopathy

  26. SALIENT FEATURES

  27. Salient Features • 32-year-old female • Recently delivered a full term baby boy • Difficulty of breathing • Orthopnea • Paroxysmal nocturnal dyspnea • Easy fatigability • Bipedal edema

  28. Salient Features • In cardiorespiratory distress • BP 130/90; HR 109bpm; RR 34 bpm • BMI: 19.5 • Distended neck veins • Dullness noted on both lower lung fields • Decrease vocal fremitus on both lateral fields Euthyroid In cardiorespiratory distress BP 130/90; HR 109bpm; RR 25bpm BMI: 19.5 Distended neck veins Subcostal retractions Dullness noted on both lower lung fields

  29. Salient Features • Decrease breath sounds on both lower lung field • Noted with bibasalcrackles • Tachycardic • Irregular rhythm • Grade 2 bipedal edema Euthyroid In cardiorespiratory distress BP 130/90; HR 109bpm; RR 25bpm BMI: 19.5 Distended neck veins Subcostal retractions Dullness noted on both lower lung fields

  30. ADMITTINGIMPRESSION

  31. Congestive heart failure probably secondary to peripartum cardiomyopathy r/o pneumonia, severe pre-eclampsia

  32. CASE DISCUSSION

  33. Harrisons 18th ed.

  34. Salient features of: • 32-year-old female • Recently delivered a full term baby boy • Difficulty of breathing • Orthopnea • Paroxysmal nocturnal dyspnea • Easy fatigability • Bipedal edema

  35. Salient features of: • In cardiorespiratory distress • Distended neck veins • Dullness noted on both lower lung fields • Decrease vocal fremitus on both lateral fields

  36. Salient features of: • Decrease breath sounds on both lower lung field • Noted with bibasal crackles • Tachycardic • Irregular rhythm • Grade 2 bipedal edema :

  37. Chest Xray of:

  38. Framingham Criteria of: MAJOR • Paroxysmal nocturnal dyspnea • Neck vein distention • Rales • Radiographic cardiomegaly • Acute pulmonary edema • S3 gallop • Increased central venous pressure (>16 cm H2O at right atrium) • Hepatojugularreflux • Weight loss >4.5 kg in 5 days in response to treatment MINOR • Bilateral ankle edema • Nocturnal cough • Dyspnea on ordinary exertion • Hepatomegaly • Pleural effusion • Decrease in vital capacity by one third from maximum recorded • Tachycardia (heart rate>120 beats/min.)

  39. Peripartum Cardiomyopathy of:

  40. Epidemiology of: • 4% of all cardiomyopathies • Incidence: • Geographic variations exist • 1 in 500–4000 in the USA • 1 in 1000 in South Africa • 1 in 300 in Haiti

  41. Epidemiology of: • CDC Pregnancy Related Mortality Surveillance 1991-1999 • Leading Causes of Maternal Mortality: • Embolism – 20% • Hemorrhage – 17% • Hypertension – 16% • Peripartum Cardiomyopathy- 9%*

  42. Epidemiology of: • 78% present within the first 4 months postpartum • Only 9% may present in the last month of pregnancy

  43. Etiology of: • Etiology of this disorder is unclear. • Proposed mechanisms: • nutritional deficiencies • genetic disorders • viral or autoimmune etiologies • hormonal problems • volume overload • alcohol • physiologic stress of pregnancy • unmasking of latent idiopathic dilated cardiomyopathy

  44. Clinical Presentations • Third heart sound (S3): 92% • Fourth heart sound (S4) • Tricuspid or mitral insufficiency murmurs: 43% • Displaced apical impulse: 72% • Edema • Rales • Ascites • Hepatomegaly • Jugular venous distension

  45. Alogorithm

  46. Diagnostics • Electrocardiogram or • β-type Natriuretic Peptide and • Cardiac Imaging: • Echocardiography • Cardiac MRI

  47. Patient’s ECG

  48. PPCM ECG LVH: 66% NSSTTWC: 96%

  49. BNP • As a result of elevated LV end-diastolic pressure due to systolic dysfunction, patients with PPCM commonly have an increased plasma concentration of B-type natriuretic peptide (BNP) or N-terminal pro-BNP (NT-proBNP). • 38 patients with PPCM were compared with 21 healthy mothers post-partum: • PPCM mothers: all had abnormal NT-proBNP plasma levels (mean 1727.2 fmol/mL) • Healthy mothers: mean 339.5 fmol/mL • P < 0.0001

  50. Patient’s Echocardiography
