Heart attack

The heart is a hollow muscular muscle that consists of four chambers. Two pumping chambers called Ventricles and two receiving chambers called Atriums.
A Heart Attack or known as a MI (Myocardial Infarction), which literally means death of heart muscle, occurs when there is a permanent complete blockage of one or more Coronary Arteries that delivers oxygenated blood to the heart. The severity of the attack will depend on how far up the Artery became blocked.

Signs and Symptoms of a MI

  • Signs of shock (Cardiogenic)
  • Extreme weakness
  • Feeling of impending doom
  • A Crushing pain in the chest (from the center radiating to the jaw and left arm)
  • Severe persistent chest pain (Usually last longer that 30 Minutes)

Treatment

  • CALL FOR HELP FROM EMERGENCY MEDICAL SERVICES
  • Sit the patient down, calm and reassure the patient
  • DO NOT allow the patient to walk around
  • Do a full Primary and secondary survey (See Training Aids)
  • Maintain body temperature by covering the patient
  • Monitor all vital signs till the Emergency Medical Services arrive

Angina

Angina is defined as a partial blockage of one or more of the coronary arteries. The pain can be described as a cramp of the heart. The pain usual subsides after resting or by taking medication (prescribed by your GP if a known Angina patient) if available. The pain rarely last longer than 6-8 minutes after rest or medication. If the pain persists longer that 30 minutes then treat as you would for a heart attack. Rather call for HELP early if pain is not easing after 10 minutes!
