From the Guidelines

The patient's lab results indicate mild hyponatremia, which is likely caused by volume depletion, and her physician should review her diuretic therapy and consider adjusting it to prevent further electrolyte imbalances, as suggested by the European Society of Cardiology working group on cardiovascular pharmacotherapy 1. The patient's sodium level is 133 mmol/L, which is slightly below the normal range, and her BUN/creatinine ratio is elevated at 25.0, indicating possible volume depletion.

  • The patient's kidney function appears to be adequate, with a normal creatinine level of 0.64 mg/dL and an eGFR of 93 mL/min/1.73m2.
  • The slightly elevated albumin level of 4.9 g/dL is generally not concerning.
  • The patient's potassium level is 4.2 mmol/L, which is within the normal range, but it's essential to monitor electrolyte levels, especially if she's taking diuretics, as they can increase the risk of hypokalaemia, as noted in the study by the European Society of Cardiology working group on cardiovascular pharmacotherapy 1. The patient should increase her fluid intake, aiming for approximately 2 liters of fluid daily, unless otherwise restricted, and follow up with her physician within 1-2 weeks to recheck electrolytes, especially if she experiences symptoms like dizziness, confusion, or weakness.
  • It's crucial to review the patient's medication regimen, including diuretics, to minimize the risk of electrolyte imbalances and other adverse effects, as recommended by the European Society of Cardiology working group on cardiovascular pharmacotherapy 1.
  • The patient's physician should consider the potential risks and benefits of each medication, taking into account her age, kidney function, and other comorbidities, to ensure optimal management of her hypertension and hyperlipidemia.

From the Research

Patient's Condition

The patient is a 73-year-old female with hypertension (HTN) and hyperlipidemia (HLD). Her laboratory results show:

  • Low sodium levels (133 mmol/L)
  • Normal potassium levels (4.2 mmol/L)
  • Normal chloride levels (98 mmol/L)
  • Normal CO2 levels (26 mmol/L)
  • Normal anion gap (9)
  • Normal glucose levels (90 mg/dL)
  • Normal BUN levels (16 mg/dL)
  • Normal creatinine levels (0.64 mg/dL)
  • Normal eGFR (93 mL/min/1.73m2)
  • High BUN/Creatinine Ratio (25.0)
  • Normal calcium levels (9.6 mg/dL)
  • Normal AST (SGOT) levels (22 unit/L)
  • Normal ALT (SGPT) levels (14 unit/L)
  • High alkaline phosphatase levels (67 unit/L)
  • Normal total protein levels (7.3 g/dL)
  • High albumin levels (4.9 g/dL)
  • Normal total bilirubin levels (0.4 mg/dL)

Relevant Studies

  • A study on fluid and electrolyte imbalances 2 highlights the importance of maintaining balance in patients, but does not directly relate to the patient's condition.
  • A study on treatment and control of blood pressure and lipids in patients with hypertension and additional risk factors 3 suggests that patients with high cardiovascular risk should be treated more intensively, but does not provide specific guidance on the patient's laboratory results.
  • A study on lifestyle changes in relation to initiation of antihypertensive and lipid-lowering medication 4 found that medication initiation is associated with both favorable and unfavorable lifestyle changes, but does not directly relate to the patient's condition.
  • A study on antihypertensive medications and their effects on lipid metabolism 5 discusses the importance of regulating hypertension and hyperlipidemia, but does not provide specific guidance on the patient's laboratory results.
  • A study on combining antihypertensive and antihyperlipidemic agents 6 suggests that a single-pill combination of antihypertensive and lipid-lowering medications can be effective in managing cardiovascular risk, but does not directly relate to the patient's condition.

Key Findings

  • The patient's laboratory results show mostly normal values, with some exceptions (low sodium, high BUN/Creatinine Ratio, high alkaline phosphatase, and high albumin).
  • The studies reviewed do not provide specific guidance on the patient's laboratory results, but highlight the importance of managing hypertension and hyperlipidemia to reduce cardiovascular risk.
