Heart Failure: Identifying Symptoms, Exploring Treatment Options, and Additional Insights
Systolic congestive heart failure, also known as heart failure with reduced ejection fraction (HFrEF), is a serious condition that affects the heart's ability to pump blood effectively. This article explores some of the most common causes of systolic congestive heart failure.
Coronary artery disease (CAD) is one of the leading culprits. Narrowing or blockage of the coronary arteries reduces blood flow to the heart muscle, leading to weakened heart tissue and reduced pumping ability. A previous heart attack, or myocardial infarction, can also cause irreversible damage to the heart muscle, significantly impairing its ability to pump blood effectively.
High blood pressure, or hypertension, is another significant factor. Chronic high blood pressure forces the heart to work harder, which can lead to enlargement and weakening of the heart muscle over time.
Cardiomyopathy, diseases of the heart muscle itself, can also lead to systolic heart failure by affecting the heart's ability to contract and pump blood efficiently. Viral infections and myocarditis, inflammation of the heart muscle, can impair the heart's pumping function, particularly if caused by viral infections.
Congenital heart defects, structural abnormalities present at birth, can lead to heart failure by affecting the heart's pumping efficiency. Abnormal heart rhythms, or arrhythmias, can increase the workload on the heart, potentially leading to failure.
Diabetes, excessive alcohol consumption, and certain medications can directly damage the heart muscle, impairing its function.
Treatments for congestive heart failure include a variety of medications such as beta-blockers, angiotensin converting enzyme inhibitors (ACE-inhibitors), angiotensin receptor blockers (ARBs), aldosterone antagonists, diuretics, and medications to control blood pressure and cholesterol. Doctors may also recommend surgery to address the underlying cause of heart failure, such as coronary artery bypass graft, percutaneous coronary intervention (PCI), pacemaker, cardiac ablation, heart valve surgery, implantable left ventricular assist device, and heart transplant.
Anyone experiencing symptoms of heart failure, such as congestion in the lungs, fluid retention, fatigue, dizziness, irregular and rapid heartbeats, and swelling due to fluid retention, should see a doctor for a diagnosis. Doctors diagnose congestive heart failure through a series of tests including blood and urine tests, chest X-ray, electrocardiogram, echocardiogram, stress test, cardiac MRI or CT scan, PET scan, and angiogram.
Congestive heart failure affects millions of people in the U.S., and treatments can provide symptom relief and improve quality of life, but doctors cannot always reverse the damage involved. The outlook for congestive heart failure depends on the type, severity, and individual factors such as overall health and age. Half of people with a diagnosis of heart failure are likely to live another 5 years or longer, while 10% to 20% with advanced heart failure may live 1 year or longer after diagnosis.
Despite the challenges, it's important to remember that with treatment, many people continue to function and enjoy a good quality of life. Conditions that can cause congestive heart failure can often be managed, and lifestyle measures such as giving up smoking, eating a nutritious diet, exercising regularly, maintaining a moderate weight, limiting alcohol, getting enough quality sleep, reducing stress, and keeping up to date with vaccinations can help.
