  3. Agenda • Heart failure and the kidney • CKD and CV problems • Definition and pathogenesis of CRS • Management • Summary

  4. HF and the kidney

  5. Low GFR Is a Risk Factor for CV Outcome Post MI GFR ≥75.0 mL/ min/1.73 m2 GFR 60.0-74.9 mL/min/1.73 m2 GFR 45.0-59.9 mL/ min/1.73 m2 GFR <45.0mL/ min/1.73 m2 60 P<.001 50 40 Estimated Event Rate (%) 30 20 10 0 Death From CV Causes Reinfarction CHF Stroke Resus- citation Composite End Point Anavekar et al. N Engl J Med. 2004;351:1298-1295.

  6. CKD and CV problems

  7. Chronic Kidney Disease and Traditional Cardiovascular Risk Factors

  8. Cardiorenal Syndrome Definition .cont A pathophysiologic disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction in the other organ

  9. Cardiorenal syndrome classification CRS Type I (Acute Cardiorenal Syndrome) Abrupt worsening of cardiac function (e.g. acute cardiogenic shock or acutely decompensated congestive heart failure) leading to acute kidney injury CRS Type II (Chronic Cardiorenal Syndrome) Chronic abnormalities in cardiac function (e.g. chronic congestive heart failure) causing progressive and potentially permanent chronic kidney disease CRS Type III (Acute Renocardiac Syndrome) Abrupt worsening of renal function (e.g. acute kidney ischaemia or glomerulonephritis) causing acute cardiac disorder (e.g. heart failure, arrhythmia, ischemia) CRS Type IV (Chronic Renocardiac Syndrome) Chronic kidney disease (e.g. chronic glomerular or interstitial disease) contributing to decreased cardiac function, cardiac hypertrophy and/or increased risk of adverse cardiovascular events CRS Type V (Secondary Cardiorenal Syndrome) Systemic condition (e.g. diabetes mellitus, sepsis) causing both cardiac and renal dysfunction

  10. Predictors of CRS • Old age • Elevated baseline creatinine level • Low EF • Low SBP • Hypertension • DM • Drugs :diuretics ,ACEI ,NSAID ,anti platelets ,BB

  11. Why does the kidney go bad? • Is it low cardiac output ? • Is it high right atrial pressure and renal vein engorgement ( renal tamponade ) ? • Is it increased abdominal pressure ? • Is it diuretics ? Other drugs ? • Is it anemia ?

  12.                                                                                 <>

  13. Synergistic effect of CKD,CHF andAnemia as risk factors for Death 2 yr mortality (n~ 200,000 5% Medicare sample) % Collins, Adv studies in Med 2003

  14. Management • ?Diuretics , ?ACEi • Intropic agents • Nitroglycerines ,nitroprosside ,nesiritide • AVP antagonists • Adenosine 1 receptor antagonists • Ultra filtration • Dialysis

  15. Summary • The interaction between cardiac and renal dysfunctions constitutes the basis of the CRS • The pathogenesis of CRS is multifactorial : low CO ,renal congestion , diuretics ,increased intra abdominal pressure in addition to anemia are important contributing factors • In addition to ultrafiltration , diuretics, ACEi ,inotropic agents ,vasodilators and natruritics are promising strategies for treatment of the CRS

  16. Thank you
