Chapter 3 : Heart Attack Symptoms

Symptoms of Heart Attack arrow_upward

  • Dizzy spells or fainting fits.
  • Discomfort following meals, especially if the discomfort continues for extended periods of time.
  • Shortness of breath after slight exertion.
  • Unprovoked fatigue.
  • Pain or tightness in the chest.
  • Palpitation: unpleasant sensations of irregular or forceful beating of the heart.
  • These symptoms of heart attack should be observed minutely and should be taken care of immediately.

  • Pain is Not Always a Symptom of Heart Attack arrow_upward

  • A heart attack often starts with mild symptoms that may not be painful.
  • Many victims experience a tightness or squeezing sensation in the chest.
  • Get emergency medical help immediately if you experience any of the following symptoms for two minutes or more:
    • Pressure, fullness, squeezing, or pain in the center of the chest
    • Pain spreading to the shoulders, neck, or arms
    • Severe pain, sudden weakness, dizziness, fainting, sweating, nausea, or shortness of breath

    Congestive Heart Failure arrow_upward

  • Does not mean the heart has failed, simply means the heart is not doing an efficient job.
  • Congestive Heart Failure results from an injury or a reduction of function of the heart muscle.
  • Can be due to arteriosclerosis, hypertension, myocardial infarction, rheumatic fever, or birth defects.
  • Normally, the right side of the heart collects blood returning from the body and sends it to the lungs.
    • If the heart is failing, the blood backs up into the veins and there are signs of edema (swelling that is caused by fluid trapped in your body's tissues).
  • Normally, the left side of the heart receives the blood from the lungs and pumps it out into the body.
    • If the heart is failing, the blood is not pumped effectively.

    Normal Heart arrow_upward

  • Healthy Heart:
    • Diastole phase: Ventricles fill normally with blood.
    • Systole phase: Ventricles pump out about 60% of the blood.

    Diseased Heart with Systolic Dysfunction arrow_upward

  • The heart contracts less forcefully and cannot pump out as much of the blood that is returned to it as it normally does.
    • Diastole phase: Ventricles become enlarged.
  • More blood remains in the lower chambers of the heart (ventricles).
    • Systole phase: Ventricles pump out less than 40% to 50% of blood.
  • Blood then accumulates in the lungs, veins, or both.

  • Diseased Heart with Diastolic Dysfunction arrow_upward

  • The heart is stiff and does not relax normally after contracting, which impairs its ability to fill with blood.
    • Diastole phase: Ventricles become relatively stiff.
    • Systole phase: Ventricles pump out about 60% of the blood but the amount may be lower than normal.

    Other Symptoms of Heart Attack arrow_upward

  • Chest pressure
  • Sweating
  • Jaw pain
  • Heartburn and/or indigestion
  • Arm pain (more commonly the left arm, but may be either)
  • Upper back pain
  • General malaise (vague feeling of illness)
  • Nausea
