While the term is often used interchangeably with heart failure, congestive heart failure signifies a more severe form. It occurs when fluid backs up in the veins, leading to congestion.
What is Heart Failure?
Heart failure is a medical condition in which your heart isn’t pumping the necessary amount of blood your body needs. This failure may stem from the weakening of the heart muscle, resulting in reduced pumping capacity, or from the stiffening of the heart muscle, hindering its ability to relax and fill with blood, or both. In either case, the heart is unable to get enough blood to the body.
There are two types of heart failure:
CHRONIC
A gradual, long-term condition. This is the most common type and demands medical treatment and lifestyle adjustments to prevent life-threatening situations.
Acute
Which can onset suddenly.
Despite its seriousness, heart failure doesn’t have to hinder your life. It is more prevalent than one might think, with over 15 million people estimated to be living with heart failure in Europe alone. With the right medication and lifestyle choices, it can be effectively controlled.
Key Definitions
This measures the amount of blood the left ventricle pumps out with each contraction. A normal EF falls between 50% and 70%.
Occurs when the heart chambers stiffen, impeding sufficient blood filling.
Involves the enlargement of heart chambers over time, leading to inadequate blood pumping.
The left ventricle can’t pump enough blood to meet the body’s demands.
The right ventricle is too weak to supply sufficient blood to the lungs, causing vein congestion.
This occurs when both sides of the heart are affected by heart failure
Stages and Classes
As you familiarize yourself with the various types and severity levels of heart failure, you will come across terms like stages and classes. These measurements play a crucial role in diagnosing the disease’s severity and tailoring an appropriate treatment plan.
Stages of Heart Failure:
Classes (Functional Classes):
These classes measure an individual’s tolerance to physical activity on a scale from one to five.
Class I:
No extreme fatigue, irregular heartbeat, or breathing difficulties during ordinary activities.
Class II:
Comfortable at rest, but normal activity induces fatigue, irregular heartbeat, and breathing issues.
Class III:
Extreme symptoms arise during minor activity.
Class IV:
The heart struggles even at rest, causing discomfort with any activity.
CAUSES AND RISK FACTORS
The origins of heart failure are diverse, with various long-term or acute factors contributing to heart damage, such as heart attacks or persistent high blood pressure. Some of the most common include:
Coronary arteries DISEASE (CAD)
Cardiomyopathy or Cardiac amyloidosis
congenital heart defect (CHD)
Valve DAMAGE
Heart Attack
IRREGULAR HEARTBEAT
Additionally, heart failure can be caused or exacerbated by chronic conditions or traumatic events in the body such as:
Severe lung disease
Diabetes
Uncontrolled high blood pressure
SIGNS AND SYMPTOMS
While some people with heart failure may not have any symptoms or experience only mild ones, it is important to note that symptoms can fluctuate and vary among individuals. In many cases, symptoms tend to intensify gradually over time. Recognizing the signs of heart failure is crucial for timely intervention. Common symptoms include:
Shortness of breath, particularly when exercising or while lying down
Being unable to exercise or do normal activities like walking up stairs
Persistent cough
Swelling in your legs, ankles, feet, or abdomen
Weight gain
Bloating
Lack of appetite or nausea
Feeling very tired or weak
Dizziness
Confusion or brain fog
Light headedness
Increased heart rate
Treating and Managing Heart Failure
Upon diagnosis, your medical team will work with you to come up with a plan to manage your heart failure that can include a combination of medications, devices, surgery, and lifestyle adjustments. While heart failure isn’t curable, the treatment can be designed to slow its progression.
Depending on your specific diagnosis, your doctor may prescribe medications tailored to your needs. Common classes include beta blockers, ACE inhibitors, ARNIs, diuretics, and SGL2 inhibitors.
Some individuals with heart failure may require the assistance of devices. These devices serve various purposes, acting as a form of treatment, a bridge to heart transplant, or aiding in monitoring heart failure to minimize hospitalization. They can be either implanted in the body or external.
Abnormal heart rhythms, such as those that are too fast, too slow, irregular, or a combination, are common in some heart failure patients. Among the devices designed to restore normal heart rhythm are pacemakers, Cardiac Resynchronization Therapy (CRT), Implantable Cardioverter Defibrillators (ICDs) and Left Ventricular Assist Device (LVAD).
- Pacemakers: These devices are implanted if the heart beats too slow or too fast.
- Cardiac Resynchronization Therapy (CRT): When the symptoms of heart failure are severe, they may result from a lack of coordination between the bottom chambers of the heart (the ventricles), causing them to beat out of sync. In such cases, implanting a CRT device, called a ‘biventricular pacemaker’, can help synchronize the heart muscle contractions, thus improving its pumping function.
- Implantable Cardioverter Defibrillator (ICD): When the heart exhibits life-threatening irregular rhythms, an ICD may be attached to restore it to the proper rhythm. ICDs play a crucial role in preventing sudden cardiac death in patients experiencing ventricular fibrillation (fast and irregular heartbeats) and ventricular tachycardia (excessively rapid heartbeats in the lower chambers).
- Left Ventricular Assist Device (LVAD): In cases where the heart weakens significantly, a LVAD might be necessary. This mechanical pump can be employed while awaiting a heart transplant or as a standalone treatment for heart failure.
Advanced Monitoring Technologies – there are some new implantable devices designed to effectively manage your heart failure and minimize hospital visits. Innovative sensors can be strategically placed within the heart, offering real-time monitoring of heart pressure, fluid levels, and cardiac pumping efficiency. These advancements aim to enhance control over your heart failure condition, providing valuable insights for proactive care.
There may be situations where your doctor may recommend heart surgery or other procedures. These interventions can help with heart failure, but they are only performed when the benefits are more significant than the risks. Procedures intended to improve heart failure include coronary artery bypass, valve replacement or replacement, and heart transplantation.
Heart failure treatments are pivotal for maintaining your well-being. Not all treatments are universally applicable, so it is crucial to monitor your symptoms and communicate openly with your doctor about any changes. Never alter your treatment without consulting your doctor.
It is important to be fully present and active in your own treatment plan. While doctors have medical knowledge, you have vital and valuable knowledge too. You know yourself — your lifestyle, preferences, and priorities — better than anyone else. Here are a few ways to be an active participant in your own treatment plan:
- Preparing questions: Write down questions before appointments. Explore the questions provided further below that you can ask your doctor for further guidance.
- Seeking understanding: Continuously ask questions until you grasp the information.
- Having support: Bring a friend or family member to assist with taking notes and advocating on your behalf.
- Expressing preferences: Share your opinions, state your preferences, and communicate your needs to your care team.
Lifestyle – Living with Heart Failure
Lifestyle is a crucial factor in thriving with heart failure. Your doctor may recommend lifestyle adjustments, including avoiding alcohol and tobacco and making dietary changes. Embracing these changes step-by-step can make a significant difference. Here is some advice from heart failure patients themselves:
Follow your treatment plan exactly as you were told. Taking medications as instructed is vital for feeling better and enhancing your longevity. If you have any uncertainties, don’t hesitate to reach out to your doctor.
Heart failure symptoms vary among individuals. Find the symptom management tools that work best for you. Understanding and responding to changes in symptoms empower you to stay ahead of potential challenges.
Make the recommended dietary changes, such as reducing salt intake, managing liquids, and eliminating foods that may counteract your medications. Your diet plays a crucial role in supporting your overall health.
Physical activity makes a huge difference, even when it feels impossible. Becoming more active, even a little bit at a time, is good for the body and mind. Consult with your healthcare team to determine a suitable exercise routine.
Keep track of changes in symptoms, fluctuations in weight, or any other noticeable shifts in your body. Discuss your observations with your doctor to refine your management plan and address emerging concerns.
Boost your confidence in self-care by learning more about your heart disease. Use reliable sources to gather information and make informed decisions regarding your health. Knowledge is a powerful tool on your journey.
Maintain connections with supportive individuals in your life and seek out peers who share similar experiences. Building an emotional support network is crucial for staying motivated and focused on your health goals. Share your journey, seek advice, and offer support to others in your community.
