Heart Failure: Causes, Symptoms, and Treatment

Heart failure is a serious medical condition in which the heart is unable to pump blood efficiently to meet the body’s needs. It doesn’t mean the heart has stopped working; rather, it is functioning less effectively than normal. This condition is chronic and progressive, requiring proper diagnosis and management to improve quality of life and prevent complications.

Causes of Heart Failure:

Common causes include:
1. Coronary Artery Disease (CAD): Blocked or narrowed arteries reduce blood flow to the heart, weakening its ability to pump.
2. High Blood Pressure (Hypertension): Persistent high blood pressure forces the heart to work harder, eventually leading to stiffness or weakness.
3. Heart Attack (Myocardial Infarction): A heart attack damages heart muscle tissue, reducing its pumping efficiency.
4. Cardiomyopathy: Diseases of the heart muscle, caused by infections, alcohol abuse, or genetic factors, can impair heart function.
5. Valve Disorders: Malfunctioning heart valves disrupt blood flow and increase strain on the heart.
6. Arrhythmias: Irregular heartbeats can lead to poor blood circulation and worsen heart failure.

Symptoms of Heart Failure:

Symptoms vary depending on the severity and type of the condition. Common symptoms include:
• Shortness of Breath: Particularly during physical activity or while lying down.
• Fatigue and Weakness: Reduced blood supply to muscles leads to tiredness.
• Swelling (Edema): Fluid retention in the legs, ankles, feet, or abdomen.
• Rapid or Irregular Heartbeat: The heart compensates by beating faster or irregularly.
• Persistent Cough or Wheezing: Often accompanied by pink, frothy sputum due to fluid buildup in the lungs.
• Difficulty Concentrating: Reduced oxygen supply can affect mental clarity.
• Sudden Weight Gain: Caused by fluid retention.

Types of Heart Failure:

Types are based on how the heart is affected:
1. Left-Sided Heart Failure: The left ventricle is weakened, causing fluid buildup in the lungs.
a- Systolic Dysfunction: The heart muscle cannot pump effectively.
b- Diastolic Dysfunction: The heart muscle becomes stiff and cannot fill properly.
2. Right-Sided Heart Failure: Often a result of left-sided failure, it leads to fluid retention in the lower body.
3. Congestive Heart Failure: A term used when fluid accumulation is significant, causing noticeable symptoms.

Diagnosis of Heart Failure:

Diagnoses involves a thorough medical evaluation, including:
• Physical Exam: Checking for swelling, irregular heartbeat, or lung congestion.
• Imaging Tests: Chest X-rays, echocardiograms, or MRIs to assess heart structure and function.
• Electrocardiogram (ECG): To detect arrhythmias or signs of previous heart damage.
• Blood Tests: To measure biomarkers like B-type natriuretic peptide (BNP), which is elevated in heart failure.

Treatment Options for Heart Failure:

Treatment aims to manage symptoms, improve heart function, and address the underlying causes. Options include:

1. Lifestyle Modifications:

• Diet: Low-sodium, heart-healthy diet to reduce fluid retention and strain on the heart.
• Exercise: Regular physical activity to improve cardiovascular health.
• Weight Management: Maintaining a healthy weight to reduce strain on the heart.

2. Medications:

• Diuretics: Reduce fluid retention.
• ACE Inhibitors/ARBs: Lower blood pressure and reduce strain on the heart.
• Beta-Blockers: Slow heart rate and improve pumping efficiency.
• Aldosterone Antagonists: Help prevent fluid buildup.
• SGLT2

3. Medical Devices:

• Pacemakers: Regulate irregular heart rhythms.
• Implantable Cardioverter-Defibrillators (ICDs): Prevent sudden cardiac arrest.
• Left Ventricular Assist Devices (LVADs): Support heart function in advanced cases.

4. Surgical Interventions:

• Coronary Bypass Surgery: Improve blood flow to the heart.
• Heart Valve Repair/Replacement: Correct valve disorders.
• Heart Transplant: For end-stage heart failure.

Living with Heart Failure:

Heart failure is a manageable condition with the right care plan. Regular follow-ups with a cardiologist, adherence to medications, and healthy lifestyle choices are crucial for improving outcomes and quality of life.

Conclusion:

Heart failure is a serious but manageable condition. Early diagnosis and proactive treatment can significantly improve a patient’s prognosis and well-being. If you or someone you know experiences symptoms of heart failure, consult a healthcare provider promptly to initiate appropriate care.

Salam Salloum

Consultant Cardiologist, Specialist In Cardiac Imaging, Heart Failure, And Valve Disease. Dr. Salloum has been working in the field of cardiovascular medicine for over 20 years between cardiac surgery, cardiac intensive care, and cardiology. In 2016 he was appointed as a consultant cardiologist with a special interest Heart Failure, Valve Disease, Cardiac Imaging (Cardiac CT, Cardiac MRI, Echocardiogram, and Stress Echocardiogram), along with General cardiology (angina, hypertension, and palpitations). Dr. Salloum received his training to be a Cardiology Doctor in prestigious UK University Hospitals. He did over 2 years at Southampton University Hospital training in cardiac intensive care and post-cardiac surgery care. He did 18 months at Papworth Hospital – Cambridge spending 1 year in cardiac surgery and 6 months in advanced heart failure training including pre and post-heart transplant care. The general cardiology, echo, stress echo and cardiac CT trainings all were gained through training programme at Oxford University Hospital (John Radcliffe Hospital) where he spent over 3 years. Dr. Salloum then took over 2 years of fellowship training at The Royal Brompton Hospital – London to obtain a level 3 EACVI Accreditation in cardiac MRI. He also has the British, European, and American Board Certifications in Echocardiography. Dr. Salloum has performed over 5000 Dobutamine Stress Echo (DSE) to assess ischaemia and valve disease. He reported over 3000 cardiac MRI studies assessing ischaemia, heart structure, valve diseases, aortopathies, and different types of cardiac cardiomyopathy conditions. He also reported over 2000 cardiac CTs assessing cornary calcifications, and coronary artery diseases non-invasively. All expertise aside, Dr. Salloum’s real goal is to help those who need it. He decided becoming a virtual doctor and offering both general and cardiology services online would be the best way to do so. He committed himself to be able to offer the best advice to anyone who asks as well as provide more in-depth consultative services through the phone, internet and face to face. So rest assured, no matter what kind of issues you have faced, whether it is pre-operative, post-operative or you have been experiencing some sort of cardiovascular symptoms you feel you need to ask a doctor or cardiologist about, The UK-Cardiologist will do the absolute best to help you through this troubling time through the virtual clinic and online services. Dr. Salloum will pass this experience on to everyone who needs to ask a cardiologist anything online. Qualifications: M.D. MRCP UK. CMR Level 3 EACVI: Cardaic MRI. CTCA SCCT II: Cardiac CT.
