First Aid for Myocardial Infarction
Myocardial infarction, commonly known as a heart attack, occurs when blood flow to the heart muscle is severely reduced or blocked, leading to ischemic necrosis of the myocardium. This is a life-threatening condition that requires immediate medical attention.
What is Myocardial Infarction?
Myocardial infarction is caused by a sudden reduction or interruption of blood flow to the heart, often due to coronary artery disease. This results in prolonged acute ischemia and necrosis of the affected myocardium.
Key Symptoms:
- Persistent, severe chest pain behind the sternum
- Stabbing pain in the precordial area, lasting for several hours
- Pallor and clammy skin
- Profuse sweating
- Weak, rapid, and irregular pulse
- General fatigue and restlessness
- Fever and elevated white blood cell counts
- Elevated serum cardiac enzymes
Complications:
- Arrhythmias
- Shock
- Heart failure
Recognizing Early Warning Signs
Although myocardial infarction often develops suddenly, it can sometimes be preceded by warning signs or predisposing factors:
– Heavy lifting or intense physical exertion
– Severe mental stress
– Overeating or consuming alcohol
– Smoking
– Exposure to cold temperatures
These factors increase the workload on the heart, leading to myocardial ischemia, which can trigger a heart attack.
Immediate First Aid Measures
- Call Emergency Services: Dial your local emergency number immediately. Do not attempt to drive the patient to the hospital yourself.
- Keep the Patient Calm: Have the patient sit or lie down in a comfortable position. Encourage slow, deep breathing to reduce stress on the heart.
- Administer Aspirin: If available and not contraindicated, give the patient a single dose of aspirin (chewed) to help thin the blood.
- Monitor Vital Signs: Check for breathing, pulse, and consciousness. Be prepared to perform CPR if the patient becomes unresponsive.
- Avoid Physical Activity: Ensure the patient remains still to minimize strain on the heart.
Prevention and Risk Management
To reduce the risk of myocardial infarction:
– Maintain a healthy diet and exercise regularly.
– Avoid smoking and excessive alcohol consumption.
– Manage stress through relaxation techniques or counseling.
– Control underlying conditions such as hypertension, diabetes, and high cholesterol.
