Signs of Heart Blockage (Coronary Artery Disease)

Introduction

Heart blockage, also known as coronary artery disease (CAD), occurs when the blood flow to the heart is restricted due to the buildup of plaques in the coronary arteries. This condition can lead to serious complications such as angina (chest pain), heart attack, or heart failure.

Common Symptoms of Heart Blockage

It is important to recognize the warning signs of heart blockage early, as timely medical intervention can prevent serious outcomes. Symptoms may include:

1. Chest Pain or Discomfort (Angina)

• A feeling of pressure, tightness, or pain in the chest, often triggered by physical exertion or stress.
• May radiate to the arms, neck, jaw, back, or stomach.
• Usually subsides with rest or nitroglycerin.

2. Shortness of Breath

• Difficulty breathing, especially during physical activity or even at rest.
• May indicate reduced oxygen supply to the heart.

3. Fatigue

• Unusual tiredness, especially during routine activities.
• Often experienced by women and older adults.

4. Heart Palpitations

• An irregular heartbeat or a sensation of the heart pounding or fluttering.

5. Dizziness or Lightheadedness

• Feeling faint or experiencing sudden weakness.
• Can be caused by reduced blood flow to the brain.

6. Nausea and Sweating

• Unexplained nausea, vomiting, or excessive sweating, often mistaken for digestive issues.
• More common in heart attack cases.

When to See a Doctor

Seek immediate medical help if you experience: - Severe chest pain lasting longer than a few minutes. - Chest pain that spreads to the arms or jaw. - Shortness of breath accompanied by chest discomfort.

Risk Factors for Heart Blockage

Understanding the risk factors can help in prevention and early detection: - High blood pressure and high cholesterol. - Diabetes and obesity. - Smoking and excessive alcohol consumption. - Sedentary lifestyle and poor diet. - Family history of heart disease.

Prevention and Management

• Adopt a heart-healthy diet (rich in vegetables, fruits, and whole grains).
• Exercise regularly and maintain a healthy weight.
• Manage stress and get enough sleep.
• Quit smoking and limit alcohol intake.
• Regular check-ups to monitor blood pressure, cholesterol, and glucose levels.

Early detection and lifestyle changes can significantly reduce the risk of severe complications!
