From the Guidelines
For an 86-year-old patient with Heart Failure with preserved Ejection Fraction (HFpEF) on torsemide therapy who is clinically euvolemic but has an elevated Brain Natriuretic Peptide (BNP) level of 242, the next step should be to consider adding a mineralocorticoid receptor antagonist (MRA) to their treatment regimen, as recommended by the ACC/AHA guidelines 1. The patient's current torsemide regimen (40 mg in the morning and 20 mg in the evening) should be continued, with careful attention to fluid status and potential adjustments as needed. The elevated BNP level indicates an increased risk for cardiac events, and the addition of an MRA, such as spironolactone, has been shown to reduce morbidity and mortality in patients with heart failure, including those with HFpEF 1. It is essential to monitor the patient's renal function, electrolyte levels, and blood pressure closely when initiating MRA therapy, as they may be at increased risk for hyperkalemia and worsening renal function 1. Regular follow-up appointments and careful monitoring of the patient's condition will help to ensure the best possible outcomes and minimize the risk of complications. Key aspects of management include:
- Continuing the current torsemide regimen with careful monitoring of fluid status
- Adding a mineralocorticoid receptor antagonist (MRA) to the treatment regimen
- Close monitoring of renal function, electrolyte levels, and blood pressure
- Regular follow-up appointments to assess the patient's condition and adjust the treatment plan as needed.

The patient is clinically euvolemic, and the elevated BNP level indicates increased risk for cardiac events. However, the provided drug labels do not directly address the next step for an 86-year-old patient with Heart Failure with preserved Ejection Fraction (HFpEF) on torsemide.
- The labels discuss potential interactions and side effects, but do not provide guidance on managing HFpEF or elevated BNP levels.
- There is no information on adjusting the torsemide dose or adding other medications to manage the patient's condition. The FDA drug label does not answer the question.
From the Research
Patient Profile
- The patient is 86 years old with Heart Failure with preserved Ejection Fraction (HFpEF)
- Currently on torsemide (loop diuretic) 40 mg in the morning and 20 mg in the evening
- Clinically euvolemic
- Elevated Brain Natriuretic Peptide (BNP) level of 242, indicating increased risk for cardiac events
Clinical Implications of Elevated BNP
- Elevated BNP levels are associated with a higher risk of cardiac events and poor prognosis in patients with heart failure 2, 3, 4, 5
- BNP levels can be used to identify patients at high risk for future cardiovascular events, even in the absence of symptoms 2
- High BNP levels are associated with increased mortality, recurrent myocardial infarction, and new heart failure 3, 4, 5
Management Considerations
- The patient's elevated BNP level suggests a higher risk of cardiac events, despite being clinically euvolemic
- The current treatment with torsemide may need to be optimized or additional therapies considered to reduce the risk of cardiac events 6
- Close monitoring of the patient's condition, including regular BNP level checks, may be necessary to guide therapy and reduce the risk of adverse outcomes 6, 5
Prognostic Value of BNP
- BNP levels can provide prognostic information on the risk of cardiac events and mortality in patients with heart failure 2, 3, 4, 5
- A BNP level of 242 in this patient indicates a higher risk of cardiac events and poor prognosis, highlighting the need for close monitoring and optimized treatment 2, 3, 4, 5
