Introduction
Did you know that more than 64.3 million people around the world are living with heart failure? https://www.escardio.org/Education/Topics/Heart-Failure It’s a serious problem where the heart can’t pump enough blood to meet the body’s needs. Understanding the heart failure causes is the first step toward living a healthier life and taking better care of your heart.
This guide will help you learn about the most common causes of heart failure, new risk factors that are being studied, and what you can do to prevent it. You’ll also learn how to recognize the symptoms and where to find help. Importantly, heart failure incidence is increasing, particularly among younger individuals, possibly linked to obesity, diabetes, and hypertension.
What is Heart Failure? Understanding the Basics
What is heart failure? It simply means your heart isn’t pumping blood as well as it should.
There are two main types: systolic heart failure, where the heart muscle is weak and can’t squeeze properly (also called reduced ejection fraction), and diastolic heart failure, where the heart muscle is stiff and can’t relax properly (also called preserved ejection fraction).
Your heart has two sides, a left and right. The left side pumps blood to the body, and the right side pumps blood to the lungs. If one side isn’t working well, it can cause problems in other parts of the body.
“Congestive” heart failure means that fluid is building up in your lungs and other parts of your body. This fluid buildup is what causes many of the symptoms. We will discuss the causes of congestive heart failure in more detail below.
The Primary Culprits: Common Causes of Heart Failure
Many things can lead to heart failure, but some causes are more common than others. Knowing these primary heart failure causes can help you understand your risk and take steps to protect your heart.
Coronary Artery Disease (CAD): The Leading Cause
Coronary artery disease, or CAD, is the most common cause of heart failure. What causes coronary artery disease? CAD happens when the arteries that supply blood to your heart become narrow or blocked.
This narrowing is caused by a buildup of plaque, called atherosclerosis. When the heart muscle doesn’t get enough blood, it can weaken over time and lead to heart failure.
Risk factors for CAD include high cholesterol, high blood pressure, smoking, and diabetes. If you have any of these risk factors, it’s important to talk to your doctor.
Treatments for CAD include medications to lower cholesterol and blood pressure, as well as procedures like angioplasty (opening up blocked arteries with a balloon) and bypass surgery (creating new routes for blood to flow around blocked arteries). Learn more about understanding and managing coronary artery disease.
High Blood Pressure (Hypertension): A Silent Threat
High blood pressure, also called hypertension, is another major cause of heart failure. How does high blood pressure lead to heart failure? When your blood pressure is too high for a long time, it makes your heart work harder to pump blood.
This extra work can cause the heart muscle to thicken (hypertrophy). Over time, the thickened heart muscle can become stiff and weak, leading to heart failure.
High blood pressure is often called a “silent threat” because it doesn’t usually cause symptoms. That’s why it’s important to get your blood pressure checked regularly.
The target blood pressure range is generally less than 130/80 mmHg. Lifestyle changes like eating a healthy diet, exercising regularly, and reducing stress can help manage high blood pressure. Medications are also often needed. Take a look at our guide on controlling high blood pressure and living a healthy life.
Diabetes: A Metabolic Culprit
Diabetes is a disease where your body doesn’t use sugar properly. Can diabetes cause congestive heart failure? Yes, it can.
Diabetes can damage blood vessels and nerves, which increases the risk of heart disease and heart failure. High blood sugar can also lead to stiffening of the heart muscle.
Keeping your blood sugar under control is very important for preventing heart failure if you have diabetes. Increased use of SGLT2 inhibitors is a foundational therapy for both HFpEF and HFrEF, regardless of diabetes status. https://www.jacc.org/ https://onlinelibrary.wiley.com/journal/18790844

Obesity: The Strain on Your Heart
Obesity means having too much body fat. How does obesity contribute to heart failure? Being overweight or obese puts extra strain on your heart.
The heart has to work harder to pump blood through the larger body mass. This extra workload can lead to thickening of the heart muscle and eventually heart failure.
Obesity is also often linked to other risk factors like high blood pressure and diabetes, which further increase the risk of heart failure. Losing weight can make a big difference for your heart health.
For advice on achieving a healthy weight through nutrition and exercise, see our guide here.
Other Significant Heart Failure Causes
Besides the primary culprits, there are other important heart failure causes to be aware of:
- Heart valve disease: Problems with the heart valves can make it harder for the heart to pump blood efficiently.
- Congenital heart defects: These are heart problems that are present at birth.
- Cardiomyopathy: This is a disease of the heart muscle itself.
- Arrhythmias: Irregular heartbeats can weaken the heart over time.
- Severe anemia: Having too few red blood cells can strain the heart.
- Thyroid disease: Both overactive and underactive thyroid can affect the heart.
- Chemotherapy and radiation therapy: These cancer treatments can sometimes damage the heart.
Emerging Risk Factors: The Latest Research
Researchers are always learning more about heart failure risk factors. Here are some emerging areas of research:
Heart Failure with Preserved Ejection Fraction (HFpEF)
HFpEF is becoming more common, now accounting for about half of all heart failure cases. It’s harder to diagnose than other types of heart failure. Doctors need to do many tests to figure out if someone has HFpEF. Treatment involves managing other health problems that can contribute to it and treating symptoms. SGLT2 inhibitors may also be used. https://www.nhlbi.nih.gov/
The Role of Inflammation
Chronic inflammation (long-term swelling) in the body is now known to play a big role in heart failure. Scientists are looking for ways to use anti-inflammatory medicines to help prevent or treat heart failure. https://www.ncbi.nlm.nih.gov/pmc/
Impact of COVID-19
Getting sick with COVID-19 can cause new heart failure or make existing heart failure worse. People with heart failure are also more likely to get very sick from COVID-19. Getting vaccinated against COVID-19 is highly recommended. https://www.acc.org/
Personalized Medicine & Genetic Factors
Genes can play a role in who gets heart failure and how well they respond to treatment. Researchers are looking for genetic markers that can help them identify people who are at higher risk of heart failure and create personalized treatment plans. https://www.ahajournals.org/journal/circgen
Lifestyle and Preventative Measures
You can take many steps to lower your risk of heart failure. Making healthy lifestyle choices can have a big impact. What lifestyle changes can prevent heart failure? Here’s what you can do for heart failure prevention.
Dietary Changes for Heart Health
- Eat a low-sodium diet: Too much salt can cause your body to hold onto extra fluid, which can strain your heart.
- Eat plenty of fruits, vegetables, and whole grains: These foods are packed with nutrients and fiber that are good for your heart.
- Consider the DASH diet: The Dietary Approaches to Stop Hypertension (DASH) diet is a healthy eating plan that can help lower blood pressure and improve heart health.
- Limit saturated and trans fats: These fats can raise your cholesterol levels and increase your risk of heart disease.
- Reduce processed foods and sugary drinks: These foods are often high in sodium, sugar, and unhealthy fats.
- Watch your portion sizes: Eating too much of anything can lead to weight gain, which can strain your heart.
- Talk to a registered dietitian: A dietitian can help you create a personalized eating plan that meets your needs. https://www.mayoclinic.org/
The Importance of Exercise
- Get regular aerobic exercise: Aerobic exercise, like brisk walking, jogging, or swimming, strengthens your heart and improves your overall health.
- Aim for at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise per week: Find an activity you enjoy and make it a regular part of your routine.
- Include strength training exercises at least twice a week: Strength training helps build muscle mass, which can improve your metabolism and help you maintain a healthy weight.
- Talk to your doctor before starting a new exercise program: This is especially important if you have any existing health problems.
Stress Management Techniques
- Understand how chronic stress can hurt your heart: Long-term stress can raise your blood pressure and increase your risk of heart disease.
- Try stress-reducing activities like yoga, meditation, or spending time in nature: These activities can help calm your mind and body.
- Get enough sleep: Lack of sleep can worsen stress and increase your risk of heart problems.
- Seek support from friends, family, or a therapist: Talking to someone can help you cope with stress and manage your emotions.
Technology & Remote Monitoring
Remote patient monitoring (RPM) allows doctors to keep track of your health from a distance. It can help them catch problems early and prevent them from getting worse. Telehealth, or virtual doctor visits, makes it easier to get care, especially if you live far away from a doctor’s office. RPM has been shown to reduce hospital stays and improve health in some people with heart failure. https://www.onlinejcf.com/
Recognizing the Signs: Heart Failure Symptoms
Knowing the heart failure symptoms can help you get diagnosed and treated early.
- Shortness of breath (dyspnea): This is a common symptom and results from fluid accumulation in the lungs. https://my.clevelandclinic.org/
- Fatigue: Feeling tired all the time is another common symptom caused by reduced cardiac output. https://my.clevelandclinic.org/
- Swelling (edema) in the ankles, legs, and abdomen: This occurs due to fluid retention caused by hormonal imbalances and impaired kidney function. https://my.clevelandclinic.org/
- Rapid or irregular heartbeat
- Persistent cough or wheezing
- Weight gain from fluid retention
- Lack of appetite or nausea
- Difficulty concentrating
It’s important to remember that these symptoms can also be caused by other conditions. If you have any of these symptoms, it’s important to see a doctor for diagnosis.
Understanding Heart Failure Stages
Doctors use a system called the New York Heart Association (NYHA) Functional Classification to describe how severe someone’s heart failure is. There are four classes:
- Class I: You have heart failure, but you don’t have any symptoms during normal activities.
- Class II: You have heart failure, and you have some symptoms during normal activities, like shortness of breath or fatigue.
- Class III: You have heart failure, and you have significant symptoms during even light activities.
- Class IV: You have heart failure, and you have symptoms even when you’re resting.
Mental Health and Heart Failure
Living with heart failure can be tough on your mental health. Many people with heart failure experience depression and anxiety. It’s important to take care of your mental health as well as your physical health. Integrated care models that address both physical and mental health needs are essential. https://www.ahajournals.org/
Seeking Help and Support
If you think you might have heart failure, talk to your doctor. Early diagnosis and treatment can make a big difference.
Here are some organizations that can provide more information and support:
- American Heart Association: https://www.heart.org/
- Heart Failure Society of America: https://www.hfsa.org/
- National Heart, Lung, and Blood Institute (NHLBI): https://www.nhlbi.nih.gov/
Ask your doctor for a referral to a qualified cardiologist (a doctor who specializes in heart problems).
Conclusion
Understanding the heart failure causes, risk factors, and prevention strategies is essential for protecting your heart health. Take proactive steps to make healthy lifestyle choices, and don’t hesitate to seek medical attention if you have any concerns. Heart failure is a manageable condition with the right care and lifestyle changes. Early detection and management can significantly improve outcomes and help you live a longer, healthier life.
