GLP-1 Medications & Heart Health: What Patients Should Know
GLP-1 medications have been used for decades to help manage certain metabolic conditions such as type II diabetes, and there is extensive data that support their safety. Research is now growing around their potential role in the prevention and treatment of cardiovascular disease.
What Are GLP-1 Medications?
GLP-1 medications are a class of drugs that work by mimicking a naturally occurring hormone involved in blood sugar regulation and metabolic signaling. There are different variations of GLP-1 medications including semaglutide, tirzepatide and more. Initially developed to support the management of certain metabolic conditions, GLP-1 medications have been studied extensively over the past several decades.
How do GLP-1 Medications Help Patients with Cardiovascular Disease?
GLP-1 medications do not “treat” cardiovascular disease the way a stent or bypass does. What they can do is reduce the risk of major cardiovascular events, such as stroke or heart attack, in specific patient populations.
GLP-1 medications influence several factors that directly affect cardiovascular health including glucose regulation, insulin sensitivity and inflammation reduction. Improving these factors can help to reduce the overall workload and stress placed on the cardiovascular system.
GLP-1 Medications Are Not a “One Size Fits All” Solution
GLP-1 medications affect multiple systems in the body and should be used under medical supervision, as part of an individualized treatment plan. When determining if a GLP-1 is a good option, providers will consider the full scope of a patient’s health, including medical history, risk factors, current therapies, and patient goals, when determining which approach is most appropriate.
As with any medication, GLP-1 medications come with their own list of side effects and drawbacks including:
- GLP-1 medications are not tolerated well by everyone, and GI side effects are common. Some patients never adjust, even with slow titration.
- GLP-1 medications require ongoing use to maintain their benefit and should not be viewed as a short-term intervention.
- Maintaining proper nutrition while on a GLP-1 medication is important. GLP-1s slow the digestive system, keeping food in the stomach longer, which makes it easier for patients to eat less. That means they need to make sure they are eating nutrient-dense food, prioritizing protein and fiber.
- Cost and access to GLP-1 medications are real barriers. Even when clinically appropriate insurance coverage is inconsistent, and out-of-pocket costs can be significant. Insurance coverage is rapidly changing, so patients should consult with their insurance company.
Bottom Line
GLP-1 medications are an evolving area of cardiovascular care, with growing evidence supporting their role in reducing cardiovascular risk. While they are not for everyone and do not replace established heart therapies, they are one example of how advances in medical research are expanding the tools available to support heart and vascular health.
For patients with questions about GLP-1 medications, patients should talk with their provider. Patients who are established with a cardiologist can ask about emerging research and how it relates to their individual cardiovascular risk. Patients can also talk with their primary care provider to review their overall health and determine whether additional evaluation is needed.
