What Is Heart Disease and Why Is It Dangerous?

Heart disease refers to disorders affecting the heart and the blood vessels supplying it.
These conditions interfere with blood circulation, oxygen delivery, and heart rhythm.

Common risk factors include high cholesterol, high blood pressure, diabetes, smoking, chronic stress, genetics, unhealthy diets, lack of exercise, and obesity.

Heart disease is dangerous because the heart supplies oxygen and nutrients throughout the body.
When the heart functions abnormally, it can cause serious complications such as heart attack, heart failure, arrhythmia, loss of consciousness, or even death.

In early stages, heart disease often progresses silently, making regular heart checkups and preventive care essential.

10 Heart Disease Symptoms You Should Not Ignore

Heart disease may begin without obvious signs. Recognizing early warning symptoms can help prevent life-threatening events.

1. Chest Tightness from Coronary Artery Disease

Chest tightness or pressure is a key symptom of coronary artery disease.
It may feel like heaviness, squeezing, or compression in the center or left side of the chest, often triggered by exertion or stress and relieved by rest.

Pain may radiate to the left arm, shoulder, neck, jaw, or upper abdomen.
Chest pain lasting more than 15–20 minutes, even at rest, requires immediate medical attention.

2. Easy Fatigue from Heart Failure

When the heart cannot pump effectively, blood and fluid accumulate in the lungs and body.
Early signs include reduced exercise tolerance, shortness of breath, and fatigue during daily activities.

3. Palpitations or Irregular Heartbeat

Heart rhythm disorders may cause rapid, slow, or irregular heartbeats.
Patients may feel pounding, fluttering, skipped beats, dizziness, or fainting.
Severe arrhythmias can increase the risk of heart failure or sudden cardiac arrest.

4. Frequent Fainting or Loss of Consciousness

Fainting caused by heart disease occurs when blood flow to the brain is temporarily reduced.
It may result from severe arrhythmias or advanced valve disease and requires thorough evaluation.

5. Swollen Legs, Feet, or Rapid Weight Gain

Poor heart function can cause fluid retention, leading to ankle or leg swelling and rapid weight gain over a few days.

6. Excessive Sweating Without Exertion

Unexplained heavy sweating, especially when combined with chest discomfort or shortness of breath, may signal acute heart ischemia or shock.

7. Shortness of Breath When Lying Flat

Patients with heart failure may feel breathless when lying down and need multiple pillows to sleep comfortably.

8. Nighttime Breathlessness or Sleep Disturbance

Sudden awakening at night with severe shortness of breath (PND) indicates fluid buildup in the lungs and requires medical evaluation.

9. Abdominal Discomfort, Nausea, or Loss of Appetite

Heart disease may mimic digestive problems such as bloating, nausea, or indigestion, especially in silent ischemia or heart failure.

10. Unexplained Anxiety or Restlessness

Sudden anxiety or a sense of impending danger without emotional triggers may result from abnormal heart rhythms or oxygen deprivation.

FAQ

Early symptoms often develop gradually, including fatigue, shortness of breath, palpitations, mild chest tightness, leg swelling, or poor sleep due to breathing discomfort.

Heart attack symptoms include severe chest pain, shortness of breath, excessive sweating, nausea, dizziness, or fainting. This is a medical emergency requiring immediate treatment.

Healthy adults should have heart checkups annually. Those with risk factors or aged over 40 should follow a cardiologist’s recommendations for more frequent screening.
