Cardiac Emergencies: Recognizing Signs, Taking Action

Heart attack:

A heart attack, also known as a myocardial infarction, occurs when the blood flow to a part of the heart muscle is blocked, usually by a blood clot. This obstruction deprives the affected area of oxygen and nutrients, leading to tissue damage or death if left untreated.

Signs and Symptoms of a Heart Attack:

  • Chest pain or discomfort: This may feel like pressure, tightness, squeezing, or heaviness in the chest, lasting for a few minutes or occurring intermittently.
  • Pain or discomfort in other areas of the upper body, including the arms, back, neck, jaw, or stomach.
  • Shortness of breath, difficulty breathing, or feeling lightheaded.
  • Nausea, vomiting, or sudden cold sweats.

Action to Take: If you or someone else experiences symptoms of a heart attack, it’s crucial to act quickly:

  1. Call Emergency Services: Dial emergency services immediately (such as 911 in the United States) to request medical assistance.
  2. Chew Aspirin: If you have aspirin available and are not allergic, chew one adult aspirin (325 milligrams) to help reduce blood clotting.
  3. Stay Calm: Encourage the individual experiencing symptoms to remain calm and avoid any unnecessary physical activity.
  4. Monitor Vital Signs: Stay with the person, monitor their vital signs, and be prepared to administer CPR if necessary.

Cardiac Arrest:

Cardiac arrest is a sudden loss of heart function, causing the heart to stop beating effectively. It is a life-threatening emergency that requires immediate intervention to restore normal heart rhythm and circulation.

Signs and Symptoms of Cardiac Arrest:

  • Sudden loss of responsiveness: The person may collapse and become unresponsive, with no pulse or breathing.
  • Absence of normal breathing or gasping for air.
  • Loss of consciousness or fainting.
  • No signs of movement or response to stimuli.

Action to Take: In the event of cardiac arrest, every second counts:

  1. Call Emergency Services: Immediately call emergency services (911 or local equivalent) to request an ambulance and defibrillator.
  2. Start CPR: Begin cardiopulmonary resuscitation (CPR) immediately by performing chest compressions and rescue breaths until help arrives.
  3. Use an Automated External Defibrillator (AED): If an AED is available, follow the device’s instructions to administer a shock to restore normal heart rhythm.

Preventing Cardiac Emergencies: While some risk factors for heart disease and cardiac emergencies, such as age and family history, cannot be changed, adopting a heart-healthy lifestyle can help reduce the risk:

  • Eat a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats.
  • Engage in regular physical activity and maintain a healthy weight.
  • Avoid tobacco use and limit alcohol consumption.
  • Manage stress levels through relaxation techniques and adequate sleep.
  • Know your risk factors and consult with a healthcare provider for preventive care and screenings.

By recognizing the signs of cardiac emergencies and taking immediate action, individuals can play a critical role in saving lives and minimizing the impact of these life-threatening events. Remember, swift action can make all the difference in preserving the health and well-being of those experiencing cardiac emergencies.
