Answer

Cardiovascular examination may reveal the following:

  • Irregular rhythms (ie, atrial fibrillation) - Thromboemboli
  • Murmurs - Endocarditis
  • Pericardial friction rub - Uremic pericarditis
  • Increased jugulovenous distention, rales, S 3 - Heart failure

In hospitalized patients, accurate daily records of fluid intake and urine output, as well as daily measurements of patient weight, are important. Hypovolemia leads to hypotension; however, hypotension may not necessarily indicate hypovolemia.

Severe heart failure may also cause hypotension. Although patients with heart failure may have low blood pressure, volume expansion is present and effective renal perfusion is poor, which can result in AKI.
