Does Entresto Lower Heart Rate? Understanding the Effects on Heart Function

Entresto, a medication combining sacubitril and valsartan, tackles chronic heart failure by improving heart function and blood flow through its dual mechanism. This can lead to a slower heart rate in some people, as a stronger heart doesn’t need to work as hard to maintain blood flow.

However, directly lowering heart rate isn’t the main goal. Entresto’s primary function is to improve heart failure symptoms and overall heart health.

Entresto: A Dual-Action Approach to Heart Failure

Entresto, a prescription medication combining sacubitril and valsartan, tackles chronic heart failure by addressing two root causes. Sacubitril inhibits an enzyme that breaks down hormones promoting blood vessel relaxation, while valsartan blocks a hormone that constricts blood vessels.

This dual action improves blood flow, reduces strain on the heart, lowers blood pressure, and helps the heart pump more efficiently, ultimately improving heart function and managing chronic heart failure symptoms.

Neprilysin Inhibition:

 Entresto’s effectiveness in managing chronic heart failure stems from its unique dual-action approach. Sacubitril, a component of Entresto, works by inhibiting neprilysin, an enzyme that naturally breaks down hormones like natriuretic peptides. These peptides play a crucial role in promoting blood vessel relaxation and regulating blood pressure.

 By inhibiting neprilysin, sacubitril essentially allows these beneficial hormones to function more effectively. This enhanced hormonal activity leads to increased sodium and fluid excretion by the kidneys, ultimately reducing the workload on the heart.

This mechanism, combined with valsartan’s function of blocking a hormone that constricts blood vessels, contributes to Entresto’s ability to improve blood flow, lessen strain on the heart, and lower blood pressure, all of which are essential for effectively managing chronic heart failure.

Entresto tackles chronic heart failure through a two-pronged approach. One component, sacubitril, disrupts the breakdown of hormones that naturally relax blood vessels and regulate blood pressure. By inhibiting an enzyme called neprilysin, sacubitril allows these beneficial hormones to function more effectively.

Meanwhile, valsartan, the other component, belongs to a class of drugs known as angiotensin II receptor blockers (ARBs). These ARBs specifically target angiotensin II, a hormone that acts to constrict blood vessels and raise blood pressure, essentially blocking its action. The combined effect of these mechanisms is multifaceted. Blood vessels relax, improving overall blood flow throughout the body. 

This reduced resistance allows the heart to pump more efficiently with less strain. Additionally, Entresto helps lower blood pressure and promotes diuresis, an increase in urine output, which helps reduce excess fluid that can contribute to heart failure symptoms. Ultimately, this two-way approach helps improve heart function and disease management for chronic heart failure patients.

Does Entresto Directly Lower Heart Rate?

While Entresto’s main objective isn’t to directly target a lower heart rate, its two-pronged approach to improve heart function in chronic heart failure patients can sometimes lead to a slower heart rate as a welcome side effect.

 This happens because Entresto combines sacubitril, which inhibits an enzyme that breaks down hormones promoting blood vessel relaxation, and valsartan, which blocks a hormone that constricts blood vessels.

 This combined effect improves blood flow, reduces the workload on the heart, and lowers blood pressure. Consequently, a stronger heart that pumps more efficiently may not need to beat as fast to maintain adequate blood flow, and regulating the body’s sympathetic nervous system activity (which increases heart rate in response to stress on the heart) can also contribute to a slower heart rate in some individuals.

It’s important to remember that Entresto’s impact on heart rate varies – some people might experience a slight decrease, while others might not see a significant change. Additionally, other factors like medications, underlying health conditions, and activity level can also influence heart rate.

Improved Efficiency:

 While Entresto’s primary target isn’t directly lowering heart rate, its mechanism of action can indirectly influence it for some individuals. Imagine a stronger heart like a more efficient pump.

 It can move the same amount of blood with less effort, potentially leading to a slower heart rate as the body no longer needs it to beat as fast to maintain proper circulation. This improved efficiency is just one of the ways Entresto can contribute to better heart function in chronic heart failure patients.

Reduced Sympathetic Activity:

 Entresto’s impact on heart rate isn’t straightforward. While it doesn’t directly target a slower heart rate, the medication’s ability to improve heart function can indirectly influence it.  One way this happens is through regulating sympathetic activity. 

Heart failure can activate the body’s “fight-or-flight” system, the sympathetic nervous system, which ramps up heart rate and blood pressure. By improving heart function and reducing stress on the heart, Entresto can help regulate this overactivity, potentially leading to a slower heart rate in some individuals.

It’s important to note that Entresto’s impact on heart rate is variable.

Entresto’s influence on heart rate isn’t a one-size-fits-all situation. Some individuals might see a slight dip, while others may experience no change. It’s important to remember that other factors, including existing medications, underlying health conditions, and activity level, can also play a role in heart rate.

Considerations and Important Points

Individual Response: 

 Everyone’s body reacts differently to medication. Factors like overall health, heart failure severity, and existing medications can influence how Entresto affects heart rate. Age can also play a role, as heart rate naturally tends to decrease with age.

Focus on Overall Heart Function: 

The primary goal of Entresto therapy is to improve heart function and manage heart failure symptoms, such as shortness of breath and fatigue. While a lower heart rate can be a positive side effect, it’s not the main treatment target. Entresto has been shown to be highly effective in reducing hospital admissions for heart failure and improving quality of life for patients.

Monitoring Heart Rate:  

While Entresto doesn’t typically cause dangerously low heart rates, it’s crucial to monitor your heart rate regularly, especially when starting treatment. You can easily check your heart rate by feeling your pulse at your wrist or using a pulse oximeter. 

Discuss any concerns about a slow heart rate with your doctor. They can advise you on whether a lower heart rate is a beneficial effect in your case and can adjust your medication regimen if needed.

Consulting a Doctor: 

If you have chronic heart failure and are considering Entresto therapy,  consult with your doctor. They can assess your individual needs, explain the potential benefits and risks of Entresto, and monitor your response to treatment. This includes monitoring your heart rate to ensure it stays within a healthy range.

Additional Considerations:

Electrolytes:

 Entresto can affect the body’s electrolyte balance, particularly potassium levels. In some cases, this can lead to a slow heart rate. Your doctor will monitor your electrolytes during treatment and may adjust medications or dietary recommendations if necessary.

Underlying Conditions:

 Certain medical conditions, such as thyroid disorders, can also influence heart rate. If you have any underlying conditions that affect your heart rate, be sure to discuss them with your doctor before starting Entresto.

In Conclusion

Entresto offers a valuable tool in managing chronic heart failure. Its two-pronged approach tackles key factors that contribute to the condition. Sacubitril, one component, inhibits an enzyme that breaks down hormones responsible for blood vessel relaxation. 

This allows these hormones to function more effectively, promoting blood flow and reducing strain on the heart. Valsartan, the other component, blocks a hormone that constricts blood vessels. This combined action translates to improved blood flow, reduced workload on the heart, and ultimately, lower blood pressure.

While directly lowering heart rate isn’t the primary target of Entresto, its mechanism of action can have this beneficial side effect in some individuals. A strengthened heart that pumps more efficiently may not need to beat as fast to maintain adequate blood flow. Additionally, heart failure can trigger the body’s “fight-or-flight” response, increasing heart rate and blood pressure.

As Entresto improves heart function, it can help regulate this response, potentially leading to a slower heart rate. It’s important to remember that individual responses to Entresto can vary. While some may experience a slight decrease in heart rate, others might not see a significant change. Consulting a doctor is essential to determine if Entresto is right for you and to monitor your response to treatment, including heart rate.
