From the Guidelines
Add Hydralazine 25mg orally three times a day and consider increasing the dose to 50mg three times a day if necessary, while closely monitoring blood pressure and renal function 1. Additionally, consider adding a beta-blocker such as Carvedilol 6.25mg orally twice a day, titrating up to 25mg twice a day as tolerated, to help manage the reserved ejection fraction 1.
Key Considerations
- It is essential to optimize fluid management and consider ultrafiltration or other strategies to address fluid overload 1.
- The patient's current medications, including ARB, CCB, and Lasix, should be continued and adjusted as needed to achieve optimal blood pressure control and manage renal function.
- Close monitoring of the patient's blood pressure, renal function, and overall clinical status is crucial.
Medication Adjustments
- The dose of Hydralazine can be increased to 50mg three times a day if necessary, while closely monitoring blood pressure and renal function.
- The dose of Carvedilol can be titrated up to 25mg twice a day as tolerated.
- The patient's current medications, including ARB, CCB, and Lasix, should be adjusted as needed to achieve optimal blood pressure control and manage renal function.
Monitoring and Follow-up
- Close monitoring of the patient's blood pressure, renal function, and overall clinical status is crucial.
- Regular follow-up appointments should be scheduled to assess the patient's response to treatment and make any necessary adjustments to their medication regimen.

From the Research
Treatment Options for Hypertension in Patients with Impaired Renal Function, Fluid Overload, and Reduced Ejection Fraction
- The patient is already on ARB, CCB, and furosemide, and additional treatment options need to be considered to manage hypertension.
- Hydralazine has been shown to have potential benefits in patients with cardiovascular and renal disease, including antioxidative, anti-apoptotic, and HIF-1α stabilization effects 2.
- A study on patients with dialysis-dependent ESRD found that combination therapy with isosorbide dinitrate and hydralazine was well-tolerated and reduced recurrent intradialytic hypotension 3.
- Hydralazine has also been shown to improve ventilation and blood gas values in patients with chronic obstructive pulmonary disease and pulmonary hypertension, with effects persisting after long-term treatment 4.
- In patients with intracranial hemorrhage, hydralazine did not significantly affect intracranial pressure compared to labetalol 5.
- Fixed-dose isosorbide dinitrate/hydralazine has been shown to improve diastolic function and exercise capacity in hypertension-induced diastolic heart failure, although it did not reduce left ventricular hypertrophy or cardiac fibrosis 6.
Potential Benefits and Risks of Adding Hydralazine
- Potential benefits: improved blood pressure control, reduced cardiovascular risk, improved diastolic function and exercise capacity.
- Potential risks: hypotension, headache, gastrointestinal side effects, potential effects on intracranial pressure.
- The decision to add hydralazine should be based on individual patient factors, including the severity of hypertension, renal function, and overall clinical status 2, 3, 6.
