Entresto (sacubitril/valsartan) is a prescription medication used to treat chronic heart failure (CHF) and reduce the risk of hospitalization due to worsening heart failure.
It works by combining two mechanisms of action in a single pill, but does it directly lower your heart rate? Let’s delve into the details.

Entresto’s Mechanism of Action:
Not a Direct Heart Rate Reducer
Entresto tackles heart failure by working on the hormonal pathways that govern blood pressure and heart function. It achieves this by combining two key mechanisms. Sacubitril, one component of Entresto, inhibits an enzyme called neprilysin.
This enzyme naturally breaks down certain hormones, including one called natriuretic peptide. By inhibiting neprilysin, sacubitril allows natriuretic peptide to stay active for longer. Natriuretic peptide has several beneficial effects for the heart, including promoting relaxation of blood vessels and lowering blood pressure.
Valsartan, the other component of Entresto, is an angiotensin II receptor blocker (ARB). Angiotensin II is a hormone that causes blood vessels to constrict, thereby raising blood pressure.
Valsartan blocks the action of angiotensin II on these receptors, allowing blood vessels to relax and blood pressure to decrease. By combining these two mechanisms, Entresto offers a comprehensive approach to managing heart failure.
Sacubitril:
This component inhibits a specific enzyme called neprilysin. This enzyme breakdown natural substances in the body that help relax blood vessels and regulate sodium excretion.
By inhibiting neprilysin, sacubitril allows these beneficial substances to function for a longer duration, promoting vasodilation (widening of blood vessels) and potentially lowering blood pressure.
Valsartan:
This component belongs to a class of drugs called angiotensin II receptor blockers (ARBs). Valsartan directly blocks the action of angiotensin II, a hormone that causes blood vessels to constrict. This blockade also contributes to vasodilation and reduced blood pressure.
By working on these two pathways, Entresto helps the heart pump blood more efficiently by reducing the workload against narrowed blood vessels. This improved efficiency can indirectly influence heart rate, but it’s not the primary target.
Potential Indirect Effects on Heart Rate and Overall Cardiovascular Health
Entresto’s primary function isn’t directly regulating heart rate, but it works behind the scenes to create a more favorable environment for your cardiovascular system. By addressing underlying issues that contribute to heart strain, Entresto can indirectly influence heart rate.
This can happen through various mechanisms, such as relaxing blood vessels to improve blood flow and reduce the workload on the heart, or by regulating hormones that influence heart rate and blood pressure.
Ultimately, the improved cardiovascular health achieved through Entresto can lead to a more efficient and relaxed heart, potentially resulting in a steadier and healthier heart rate.
Reduced Afterload:
Blood pressure and heart rate are intricately linked in a delicate dance. Vasodilation, the widening of blood vessels, plays a key role in this interplay. As these vessels relax and offer less resistance, the force required by the heart to push blood through them (known as afterload) diminishes.
This translates to a lighter workload for the heart, allowing it to pump with slightly less effort. Consequently, the heart rate may slow down a tad, reflecting the reduced demand placed upon it. In essence, vasodilation creates a more relaxed circulatory environment, enabling the heart to ease up on its pumping intensity.
Improved Oxygen Delivery:
By enhancing blood flow throughout the body, Entresto can improve oxygen delivery to the heart muscle. This can potentially allow the heart to function more efficiently, reducing the need to beat faster to compensate for oxygen deficiency.
Potential for Neurohormonal Modulation:
Chronically stressed hearts often release hormones that can further increase heart rate and blood pressure. Entresto’s effects on these hormonal pathways might offer some additional benefit in regulating heart rate, although more research is needed to fully understand this aspect.
Who Should Monitor Heart Rate While Taking Entresto?
Entresto’s impact on heart rate can vary from person to person. Some individuals might experience a mild slowing of their heart rate, but this isn’t a universal effect. It’s particularly important for those with pre-existing heart conditions or a history of slow heart rate (bradycardia) to monitor their heart rate more closely while taking Entresto.
This allows for early detection of any potential complications and ensures they receive proper medical guidance if their heart rate dips too low.
People with Underlying Heart Rhythm Issues:
Entresto, a medication used to manage chronic heart failure, offers significant benefits, but it’s important to consider any pre-existing conditions you might have before starting treatment. One such condition is bradycardia, a slow heart rate.
If you have bradycardia, your doctor will likely want to closely monitor your heart rate throughout your Entresto treatment plan.
This is because Entresto can potentially slow your heart rate even further. Additionally, some medications can affect heart rhythm. If you’re taking any medications that could impact your heart rate, be sure to discuss them with your doctor before starting Entresto.
By openly communicating about any pre-existing conditions or medications, you and your doctor can work together to ensure Entresto is the right course of action for you, and if so, closely monitor your heart rate to optimize the treatment’s effectiveness and minimize any potential side effects.
Those Taking Beta-Blockers:
Beta-blockers, a category of medication, are frequently prescribed to tackle heart-related issues like heart failure and high blood pressure. Their mode of action involves directly reducing the heart rate.
This can be particularly important if you’re also taking Entresto, another medication that can influence heart rate. To ensure your heart rate stays within a safe range and doesn’t dip too low, your doctor will likely monitor it closely while you’re on both medications.
The Importance of Consulting Your Doctor and Individualized Treatment
Entresto is a powerful medication for managing chronic heart failure. However, individual responses to medication can vary. Factors like underlying health conditions, medications, and overall health can influence how Entresto affects your heart rate and blood pressure.
Tailored Treatment Plan:
Your doctor can assess your individual needs and create a treatment plan that considers your specific heart function, blood pressure, and any existing conditions. This might involve using Entresto alongside other medications or adjusting the dosage to achieve optimal results.
Monitoring Heart Rate and Blood Pressure:
Maintaining regular checkups with your doctor is crucial when taking Entresto, as it allows for close monitoring of your heart health and potential side effects. During these appointments, your doctor will measure your blood pressure and heart rate to ensure they remain within a healthy range.
This proactive approach enables early detection of any issues that might arise from taking Entresto, allowing for prompt intervention and adjustments to your treatment plan as needed. By staying vigilant and attending regular checkups.
Addressing Concerns:
Entresto, while effective for many, can bring about changes in heart rate for some users. This is especially true during the initial adjustment period. If you notice any fluctuations in your heart rhythm or experience any worrisome symptoms at all, don’t delay in reaching out to your doctor.
They are best equipped to understand these changes in the context of your individual health and can guide you accordingly. In some cases, a simple conversation might be enough to ease your concerns.
In others, your doctor might recommend adjustments to your dosage or even explore alternative treatment options if needed. By keeping an open line of communication with your doctor, you can ensure you receive the most personalized and effective care plan possible..
Remember:
Maintaining a consistent and doctor-approved Entresto dosage is crucial for managing your heart health. While it may seem tempting to adjust your medication regimen on your own, it’s important to remember that your doctor has the expertise and knowledge to determine the most effective and safe course of treatment for your specific needs.
They will consider factors like your overall health, other medications you’re taking, and the severity of your heart condition to establish the optimal Entresto dosage. Abruptly changing or stopping your medication can disrupt this delicate balance and potentially worsen your heart health.
By working closely with your doctor and following their prescribed Entresto dosage, you can ensure you’re receiving the best possible support for your heart.
