Understanding Heart Blockage vs. Heart Attack is crucial for early diagnosis and life-saving treatment. Many people assume both are the same, but medically they are different conditions. In this guide, we break down the difference in simple terms with expert insights from Dr. Ajay Bahadur, Apollomedics – a leading heart specialist in Lucknow.
What Is Heart Blockage? Heart Blockage vs. Heart Attack
A heart blockage occurs when cholesterol, fat, or plaque builds up inside the coronary arteries. This buildup narrows the arteries and reduces blood flow to the heart. While it may not always cause symptoms, it increases the risk of a future heart attack.
Common Symptoms of Heart Blockage
- Chest discomfort during exertion
- Shortness of breath
- Fatigue
- Dizziness
- Pain radiating to jaw, back, or arms
Why It Happens
- High cholesterol
- High blood pressure
- Diabetes
- Smoking
- Sedentary lifestyle
- Family history
What Is a Heart Attack?
A heart attack happens when a coronary artery becomes completely blocked, stopping blood flow to a part of the heart muscle. This causes severe chest pain and can permanently damage the heart if not treated immediately.
Symptoms of a Heart Attack
- Sudden, intense chest pain
- Sweating
- Breathlessness
- Nausea/vomiting
- Uneasiness or restlessness
- Pain spreading to shoulder, left arm, back, neck, or jaw
