Cardiomyopathy laboratory findings

Introduction

Overview

Overview

Hyponatremia can be seen in patients with cardiomypathy and other causes of HF: it has prognostic implications; as it indicates the activation of the renin-angiotensin system in response to the stress of the cardiomyopathy and/or heart failure. Kidney function could be affected as a result of medication-toxicity, volume depletion in cases of excessive diuresis, or development of cardiorenal syndrome. Brain natriuretic peptide (BNP) is usually elevated in systolic heart dysfunction: it can also be falsely elevated in renal failure and pulmonary embolism. On the other hand, it can be falsely low in obese patients.

Cardiomyopathy Laboratory Findings

  • Hyponatremia can be seen in patients with cardiomypathy and other causes of HF: it has prognostic implications; as it indicates the activation of the renin-angiotensin system in response to the stress of the cardiomyopathy and/or heart failure.[1]
  • Kidney function could be affected as a result of medication-toxicity, volume depletion in cases of excessive diuresis, or development of cardiorenal syndrome.[1]
  • Brain natriuretic peptide (BNP) is usually elevated in systolic heart dysfunction: it can also be falsely elevated in renal failure and pulmonary embolism. On the other hand, it can be falsely low in obese patients.
  • Elevated troponin levels indicate ischemic heart disease, and should be investigated as much, till coronary arterial disease is ruled out.
  • Elevated iron saturation and ferritin are indicative of hemochromatosis as a cause of cardiomyopathy.
