What is a Heart Attack?

A heart attack occurs when blood flow to a part of the heart is blocked, usually by a blood clot. This blockage prevents oxygen-rich blood from reaching the heart muscle, causing tissue damage or death. The longer the blockage persists, the more severe the damage. Quick action is critical to minimize long-term effects and save lives.

Recognizing the Signs of a Heart Attack

Heart attack symptoms can vary from person to person, and they may not always be sudden or severe. Some people experience mild symptoms, while others have intense pain. Here are the most common signs to watch for:

1. Chest Pain or Discomfort
   • A feeling of pressure, tightness, squeezing, or pain in the center or left side of the chest.
   • This discomfort may last for several minutes or come and go.
2. Upper Body Pain
   • Pain or discomfort may spread to the arms (especially the left arm), shoulders, neck, jaw, or back.
3. Shortness of Breath
   • Difficulty breathing, even without chest pain, can be a sign of a heart attack.
4. Cold Sweats and Dizziness
   • Sudden sweating, lightheadedness, or feeling faint may occur.
5. Nausea or Vomiting
   • Some people experience stomach discomfort, nausea, or vomiting during a heart attack.
6. Fatigue
   • Unusual or extreme tiredness, especially in women, can be a warning sign.
7. Other Symptoms
   • Anxiety, a sense of impending doom, or unexplained weakness may also occur.

Note: Women are more likely to experience atypical symptoms like fatigue, nausea, or back pain, which can sometimes lead to delayed diagnosis.

What to Do If You Suspect a Heart Attack

Time is critical during a heart attack. If you or someone around you shows signs of a heart attack, follow these steps:

1. Call Emergency Services Immediately
   • Dial your local emergency number without delay.
   • Do not attempt to drive yourself to the hospital.
2. Chew Aspirin (If Recommended)
   • If you have aspirin on hand and are not allergic, chewing one adult-sized aspirin (325 mg) can help thin the blood and reduce damage.
   • Always consult with emergency services before taking any medication.
3. Stay Calm and Rest
   • Sit or lie down in a comfortable position and try to stay calm.
   • Avoid any physical exertion, as it can worsen the situation.
4. Use an AED (If Available)
   • If the person loses consciousness and an automated external defibrillator (AED) is available, follow the instructions on the device.

Preventing Heart Attacks

While some risk factors like age, family history, and genetics cannot be changed, many lifestyle choices can significantly reduce your risk of a heart attack:

1. Adopt a Heart-Healthy Diet
   • Focus on fruits, vegetables, whole grains, lean proteins, and healthy fats.
   • Limit processed foods, sugar, and saturated fats.
2. Exercise Regularly
   • Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking or cycling.
3. Quit Smoking
   • Smoking is a major risk factor for heart disease. Seek help to quit if needed.
4. Manage Stress
   • Practice relaxation techniques like meditation, yoga, or deep breathing to reduce stress levels.
5. Monitor Your Health
   • Keep track of your blood pressure, cholesterol, and blood sugar levels.
   • Regular check-ups with your doctor can help catch potential issues early.
6. Maintain a Healthy Weight
   • Excess weight puts strain on your heart. Aim for a balanced diet and regular exercise to maintain a healthy weight.
