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.
