HEART FAILURE - CAUSES, SYMPTOMS & PREVENTION

Man with hand on his chest

Heart failure is a serious medical condition in which the heart is unable to pump blood efficiently to meet the body's needs. Contrary to what the name may imply, heart failure does not mean the heart has stopped working. Instead, it means the heart is functioning less effectively than normal, and without proper care, the condition can progressively worsen.

At Apex Heart Hospital, we believe in empowering our patients and their families with knowledge. Understanding the causes, risk factors, and prevention methods of heart failure is crucial for early detection and management.

What Is Heart Failure?

Heart failure, also known as congestive heart failure (CHF), occurs when the heart muscles weaken or become too stiff, making it difficult for the heart to fill with or pump enough blood. This leads to a buildup of fluid in the lungs, liver, abdomen, and lower extremities.

There are two main types of heart failure:

  • Left-sided heart failure: This is the most common type and often leads to fluid backing up in the lungs (pulmonary congestion).
  • Right-sided heart failure: This usually occurs as a result of left-sided failure and leads to fluid buildup in the abdomen, legs, and feet.

Heart failure can also be classified as:

  • Systolic failure, when the heart muscle loses its ability to contract and pump blood.
  • Diastolic failure, when the heart muscle becomes stiff and doesn’t fill properly between beats.

Common Causes of Heart Failure

Heart failure can be caused by a variety of underlying conditions that damage or overwork the heart. The most common causes include:

1. Coronary Artery Disease (CAD)

This is the leading cause of heart failure. CAD is the narrowing or blockage of the coronary arteries, usually caused by atherosclerosis. When the heart doesn’t get enough oxygen-rich blood, it becomes weak and struggles to pump efficiently.

2. High Blood Pressure (Hypertension)

When blood pressure is consistently high, the heart must work harder to circulate blood, which thickens the heart muscle and can eventually lead to heart failure.

3. Heart Attack (Myocardial Infarction)

A heart attack damages the heart muscle, reducing its ability to pump blood. If the damage is extensive, it can lead to heart failure.

4. Cardiomyopathy

This refers to diseases of the heart muscle. Causes may include genetic factors, infections, alcohol abuse, and the effects of certain drugs. Cardiomyopathy often leads to heart failure as the muscle becomes enlarged, thick, or rigid.

5. Valvular Heart Disease

Faulty heart valves (due to disease, infection, or congenital defects) make the heart work harder to maintain blood flow. Over time, this added strain can cause heart failure.

6. Arrhythmias (Irregular Heartbeats)

Chronic irregular heartbeats, especially if too fast, can weaken the heart muscle over time, resulting in heart failure.

7. Diabetes

Diabetes increases the risk of heart failure due to its link with high blood pressure, obesity, and coronary artery disease. High blood sugar levels can also damage the heart.

8. Congenital Heart Defects

Some people are born with structural heart defects. Depending on the severity, these defects can impair heart function and lead to failure later in life.

Signs and Symptoms of Heart Failure

The symptoms of heart failure can vary from person to person but typically include:

  • Shortness of breath (especially during activity or when lying down)
  • Fatigue and weakness
  • Swelling in the legs, ankles, and feet
  • Rapid or irregular heartbeat
  • Persistent cough or wheezing
  • Increased need to urinate at night
  • Weight gain from fluid retention
  • Difficulty concentrating or decreased alertness

Early detection is key. If you experience these symptoms, consult a cardiologist at Apex Heart Hospital promptly.

Risk Factors for Heart Failure

Understanding your risk is the first step toward prevention. Key risk factors include:

  • High blood pressure
  • Coronary artery disease
  • Diabetes
  • Obesity
  • Smoking
  • Excessive alcohol use
  • Sedentary lifestyle
  • Family history of heart disease
  • Age (risk increases with age)

How to Prevent Heart Failure

While not all causes of heart failure are preventable, many are manageable with lifestyle changes and proper medical care. Here’s how you can reduce your risk:

1. Control Blood Pressure

Maintain a healthy blood pressure through diet, exercise, stress management, and medication if prescribed.

2. Manage Diabetes

Keep blood sugar levels in check with the help of your healthcare provider. Uncontrolled diabetes significantly raises the risk of heart failure.

3. Quit Smoking

Smoking damages blood vessels, reduces oxygen to the heart, and contributes to plaque buildup. Quitting is one of the most important steps you can take for heart health.

4. Limit Alcohol and Avoid Illegal Drugs

Excessive alcohol and stimulant drugs like cocaine can weaken the heart muscle and trigger heart failure.

5. Eat a Heart-Healthy Diet

Focus on:

  • Fruits and vegetables
  • Whole grains
  • Lean proteins
  • Low-sodium and low-saturated fat foods
    Limit processed foods and sugary drinks.

6. Stay Active

Aim for at least 150 minutes of moderate-intensity exercise each week. Walking, swimming, and cycling are excellent options.

7. Maintain a Healthy Weight

Obesity increases the risk of many heart-related conditions. Weight loss improves blood pressure, cholesterol, and heart function.

8. Manage Stress

Chronic stress can increase blood pressure and lead to unhealthy behaviors. Practice relaxation techniques like meditation, yoga, or deep breathing.

9. Regular Checkups

Routine screenings and checkups can help detect heart problems early. At Apex Heart Hospital, our cardiologists provide comprehensive evaluations and preventive care plans.

Treatment Options at Apex Heart Hospital

If diagnosed with heart failure, treatment is focused on improving quality of life, managing symptoms, and preventing the condition from getting worse. Treatment options include:

  • Medications such as ACE inhibitors, beta-blockers, and diuretics
  • Lifestyle counseling
  • Cardiac rehabilitation
  • Surgical options like valve repair or implantable devices (e.g., pacemakers)
  • Advanced therapies in severe cases, including heart transplantation

Our multidisciplinary team at Apex Heart Hospital ensures patients receive personalized care tailored to their unique condition and lifestyle.

When to See a Doctor

If you experience persistent fatigue, swelling, or breathing difficulties, don’t wait. Early intervention can prevent complications and improve outcomes.

You can schedule a consultation with one of our expert cardiologists at Apex Heart Hospital to evaluate your risk and receive preventive guidance.
