Entresto's effect on heart rate is a significant consideration for patients and healthcare providers.
Does Entresto Slow Down Heart Rate?
Entresto, a combination medication of sacubitril and valsartan, can indeed slow down a patient's heart rate [1]. This effect is a common side effect observed in individuals taking the drug.
Why Does Entresto Affect Heart Rate?
The mechanism behind Entresto's impact on heart rate relates to its components. Sacubitril works by inhibiting neprilysin, an enzyme that breaks down natriuretic peptides. These peptides have beneficial effects, including vasodilation and natriuresis. Valsartan is an angiotensin II receptor blocker (ARB), which blocks the effects of angiotensin II, a substance that narrows blood vessels and increases blood pressure. The combined action of these drugs can lead to a decrease in heart rate as blood vessels relax and blood pressure lowers [2].
What Are the Symptoms of a Slow Heart Rate on Entresto?
A slower than usual heart rate, medically termed bradycardia, can manifest with various symptoms. Patients may experience dizziness, lightheadedness, fatigue, shortness of breath, or even fainting spells [3]. It is crucial for individuals taking Entresto to report any such symptoms to their doctor promptly.
How Often Does Entresto Cause a Slow Heart Rate?
While a slowed heart rate is a known side effect, the frequency can vary among patients. Clinical trials and post-marketing surveillance monitor these effects. If experiencing a significantly slow heart rate, a healthcare professional will assess whether Entresto is the cause and adjust the dosage or consider alternative treatments [1, 2].
When Should I Contact My Doctor About Entresto and Heart Rate?
Patients should contact their healthcare provider if they experience symptoms of a slow heart rate, such as dizziness, fainting, extreme fatigue, or shortness of breath, while taking Entresto. It is also important to discuss any pre-existing heart conditions or medications that might affect heart rate before starting treatment [1, 3].
What is the Target Heart Rate While on Entresto?
There isn't a single universal target heart rate for all patients on Entresto. The appropriate heart rate depends on the individual's overall health, the reason for taking Entresto (typically heart failure), and other medical conditions. Doctors will monitor a patient's heart rate and adjust the Entresto dosage as needed to balance therapeutic benefits with potential side effects [1, 2].
What Happens If My Heart Rate Is Too Slow on Entresto?
If a patient's heart rate becomes too slow on Entresto, a doctor will likely investigate the cause. This may involve reducing the dose of Entresto, temporarily discontinuing the medication, or prescribing other treatments to manage the bradycardia. In some cases, a pacemaker might be considered if the slow heart rate is severe or persistent [3].
