Heart failure affects millions of people worldwide, significantly impacting their quality of life. In fact, about 6.2 million adults in the United States have heart failure, and it contributes to over 379,000 deaths each year. This condition, where the heart can’t pump enough blood to meet the body’s needs, requires careful and ongoing management. This guide provides a complete and updated look at heart failure treatment options available today. It is crucial to remember that each person’s situation is unique, so treatment plans should be made together with healthcare providers. Just like understanding the foundation of a house is crucial before building, understanding the underlying causes of heart failure is crucial to effectively manage the condition, which is something we discuss in our article: Decoding Heart Failure Causes, Risks, and Prevention: A Comprehensive Guide.

Understanding Heart Failure: A Brief Recap

Heart failure treatment depends on understanding what’s causing the problem. Heart failure means the heart isn’t pumping blood as well as it should. There are two main types: heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). HFrEF happens when the heart muscle is weak and can’t squeeze strongly enough to pump out enough blood. HFpEF happens when the heart muscle is stiff and can’t relax properly to fill with enough blood. Knowing which type of heart failure a person has is very important because the treatments can be different. Understanding the causes and risk factors, which are explained in our article Decoding Heart Failure Causes, Risks, and Prevention: A Comprehensive Guide, is the first step in making treatment decisions.

Heart Failure Medications: A Detailed Overview

Heart failure medications play a big role in managing symptoms and slowing down the disease. These medicines help the heart work better and can improve how a person feels. Here’s a closer look at the different types of medicines used:

• ACE Inhibitors and ARBs:
  These medicines block the renin-angiotensin-aldosterone system (RAAS). This system raises blood pressure, so blocking it helps relax blood vessels and makes it easier for the heart to pump. Examples of ACE inhibitors are enalapril and lisinopril. Examples of ARBs are valsartan and losartan. Common side effects can include a cough, dizziness, or kidney problems. These medicines are not safe to take during pregnancy, and people who have had angioedema (swelling under the skin) should not take them.
• Beta-Blockers:
  These medicines block the effects of adrenaline. This slows down the heart rate and lowers blood pressure, which helps the heart work less hard. Examples of beta-blockers are metoprolol, carvedilol, and bisoprolol. It’s important to start with a low dose and slowly increase it to avoid side effects like fatigue, dizziness, or a slow heart rate.
• Diuretics:
  These medicines help the body get rid of extra fluid. This reduces swelling and makes it easier for the heart to pump blood. Examples of diuretics are furosemide, torsemide, and hydrochlorothiazide. When taking diuretics, it’s important to check electrolyte levels (like potassium and sodium) because these medicines can cause them to become imbalanced. Common side effects include dehydration and electrolyte imbalances.
• Angiotensin Receptor-Neprilysin Inhibitors (ARNIs):
  These medicines, like sacubitril/valsartan (Entresto), block both angiotensin receptors and neprilysin. This helps relax blood vessels and reduces the strain on the heart. ARNIs are often preferred over ACE inhibitors for people with HFrEF because they have been shown to work better. The American College of Cardiology (ACC) guidelines support this: https://www.acc.org/latest-in-cardiology/ten-points-to-remember/2022/02/12/22/15/2022-aha-acc-esc-guideline-for-the-management-of-heart-failure
• SGLT2 Inhibitors:
  These medicines, like empagliflozin, dapagliflozin, and canagliflozin, block sodium-glucose cotransporter 2 in the kidneys. This lowers blood sugar and has also been shown to help people with heart failure, even if they don’t have diabetes. They have been shown to be beneficial in HFrEF and HFpEF. Researchers are still studying exactly how SGLT2 inhibitors improve heart function, but more data continues to emerge solidifying their role in both HFrEF and HFpEF, as discussed in this article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10411998/
• Other Medications:
  Other heart failure medications that may be used in some cases include digoxin (to help the heart pump stronger), hydralazine/isosorbide dinitrate (to relax blood vessels), and vericiguat (to improve blood flow).

Heart Failure Devices: Technological Advancements

Heart failure devices can help manage symptoms and prevent sudden cardiac death. These devices are implanted in the body and use technology to help the heart work better. Here’s a look at some of these devices:

• Implantable Cardioverter-Defibrillators (ICDs):
  ICDs are designed to detect and correct life-threatening arrhythmias (irregular heartbeats). They can deliver an electrical shock to restore a normal heartbeat. Doctors decide who needs an ICD based on things like how well the heart is pumping (ejection fraction) and whether they have had arrhythmias in the past. While ICDs can be life-saving, there are also risks, such as infection or inappropriate shocks.
• Cardiac Resynchronization Therapy (CRT):
  CRT devices help improve the coordination of heart contractions. In some people with heart failure, the heart chambers don’t beat together properly. CRT uses electrical signals to make the heart beat in a more coordinated way, which can improve how well the heart pumps blood. Doctors decide who needs CRT based on factors like ejection fraction, the width of the QRS complex on an EKG, and how severe their heart failure symptoms are. Like ICDs, CRT devices also have benefits and risks.
• Left Ventricular Assist Devices (LVADs):
  LVADs are used to help the heart pump blood. These devices are used for people with severe heart failure when the heart is too weak to pump enough blood on its own. LVADs can be used as a bridge to heart transplant (while waiting for a new heart) or as destination therapy (a long-term treatment option). There are different types of LVADs, and the decision to use one depends on the person’s specific situation. Newer LVADs are smaller and more durable, with fewer complications, according to this review article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8849155/
• Leadless Pacemakers and Subcutaneous ICDs:
  These are newer types of heart failure devices. Leadless pacemakers are smaller and don’t require wires (leads) to be placed in the heart. Subcutaneous ICDs are placed under the skin and don’t require leads to be placed in the heart either. These devices have some advantages over traditional pacemakers and ICDs. More information about these devices can be found at the American Heart Association: https://www.heart.org/en/health-topics/arrhythmia/prevention–treatment-of-arrhythmia/devices-that-can-treat-arrhythmias

Advanced Heart Failure Therapies: When More is Needed

When heart failure treatment doesn’t work well enough with medicines and devices, there are advanced therapies that can help. These are usually for people with very severe heart failure.

• Heart Transplantation:
  Heart transplantation involves replacing a person’s diseased heart with a healthy heart from a donor. The process starts with a careful evaluation to see if the person is a good candidate for a transplant. There are often long waiting lists for donor hearts, and it’s important to find a heart that matches the person’s blood type and size. After a transplant, people need to take medicines to suppress their immune system and prevent their body from rejecting the new heart.
• Mechanical Circulatory Support in Pediatric Populations:
  LVAD can also be used for children who have heart failure. These devices help the child’s heart pump blood and can improve their quality of life.
  This is also discussed in a published study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8849155/

Lifestyle Modifications: A Cornerstone of Treatment

Heart failure lifestyle modifications are very important for managing the condition. These changes can help improve heart health and make medicines work better.

• Dietary Changes:
  Eating a healthy diet is very important for people with heart failure. A low-sodium diet is usually recommended to help reduce fluid retention. It’s also important to eat plenty of fruits, vegetables, and whole grains. Personalized nutrition plans, tailored to individual needs and preferences, may be helpful. You can read more about the importance of diet in this article from the European Journal of Preventive Cardiology: https://www.escardio.org/Journals/European-Journal-of-Preventive-Cardiology/Article/ArticleDetails/2979
• Exercise and Cardiac Rehabilitation:
  Regular exercise can help improve heart function and overall health. Aerobic exercise (like walking or cycling) and strength training are both good options. Cardiac rehabilitation programs can provide support and guidance to help people exercise safely and effectively.
• Stress Management:
  Chronic stress can negatively affect heart health. Finding ways to manage stress, such as yoga or meditation, can be helpful.
• Managing Sleep Apnea:
  Sleep apnea is a condition where a person stops breathing for short periods during sleep. This can put extra stress on the heart. Getting treatment for sleep apnea can improve heart health.

The lifestyle advice such as diet and exercise discussed in our article Decoding Heart Failure Causes, Risks, and Prevention: A Comprehensive Guide are also important for heart failure treatment.

Treating HFpEF vs. HFrEF: Tailoring the Approach

The HFpEF treatment approach differs from HFrEF. It’s important to remember that treatment strategies are different for HFpEF and HFrEF. HFrEF has well-established treatment guidelines. These guidelines include using medicines like ACE inhibitors, beta-blockers, and ARNIs. HFpEF is more challenging to treat. The role of SGLT2 inhibitors are emerging in HFpEF treatment. Managing other health problems, like high blood pressure and diabetes, is very important. Researchers are also working to find new therapies that target the specific causes of HFpEF. The differences in the pathophysiology of HFpEF and HFrEF necessitate varying treatment approaches and targets. More information can be found in this review: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9341994/

Emerging Therapies: The Future of Heart Failure Treatment

Heart failure treatment is constantly evolving. Researchers are working on new therapies that could improve outcomes for people with heart failure.

• Pharmacological Therapies:
  Researchers are studying new medicines that could help people with heart failure. For example, vericiguat is a medicine that stimulates soluble guanylate cyclase and has been shown to improve outcomes in people with worsening heart failure. Gene therapies that target calcium handling and cardiac contractility are also being studied. Targeted anti-inflammatory therapies may also help by reducing inflammation in the heart. New research is being performed all the time as discussed in this research: https://www.ahajournals.org/doi/10.1161/JAHA.121.024214
• Minimally Invasive Procedures:
  Transcatheter mitral valve repair (TMVR) and replacement (TMVR) techniques are being developed to provide less invasive options for people with mitral regurgitation (a leaky heart valve) that contributes to heart failure. Researchers are also working on percutaneous approaches to tricuspid valve repair. You can read more about the advancements in TMVR in this article: https://www.jacc.org/doi/10.1016/j.jacc.2023.04.050
• Remote Monitoring and AI-Powered Management:
  AI algorithms are being developed to predict heart failure exacerbations (worsening of symptoms) based on data collected from remote monitoring devices (like weight scales, blood pressure monitors, and activity trackers). These systems can trigger early interventions to prevent hospitalizations. Smartwatches and other wearable devices are also being used to monitor people at home. The use of AI in remote monitoring is explained in this article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9032432/
• Regenerative Medicine and Cell-Based Therapies:
  Stem cell therapy is being studied as a way to repair damaged heart muscle. Researchers are investigating different types of stem cells and delivery methods. Gene editing techniques (like CRISPR) are also being explored to correct genetic mutations that contribute to heart failure. More details are discussed in this research: https://www.ahajournals.org/doi/10.1161/CIRCRESAHA.121.318747

Navigating End-of-Life Care and Device Deactivation

When heart failure treatment is no longer working and a person is nearing the end of life, it’s important to have open and honest conversations about end-of-life care. This includes discussing the person’s wishes for medical treatment and quality of life. It’s also important to address the ethical considerations surrounding device deactivation (like turning off ICDs or CRTs) in people with advanced heart failure. This should be a shared decision-making process between the person, their family, and their healthcare providers.

Conclusion

In summary, there are many heart failure treatment options available today. These range from medicines and devices to lifestyle changes and advanced therapies. It’s important to remember that each person’s situation is unique, and treatment plans should be made together with healthcare providers. With ongoing research and advancements in technology, there is hope for improved outcomes and a better quality of life for people with heart failure.
