Heart Attack – Symptoms, Causes and Prevention

Heart Attack

A heart attack is the demise of a segment of heart muscle caused by a loss of blood supply. The blood is typically cut off when an artery supplying the heart muscle is blocked by a blood clot.

Symptoms of Heart Attack

Most Common heart attack marks and symptoms include:

  • Pressure, tightness, pain, or a squeezing or stinging sensation in your chest or arms that may spread to your neck, jaw or back
  • Nausea, dyspepsia, heartburn or abdominal pain
  • Squatness of breath
  • Cold sweat
  • Fatigue
  • Lightheadedness or unexpected dizziness

Warning Signs

As heart attacks can be fatal, it is vital to identify the warning signs that an attack is stirring.

While the symptoms enumerated above are all linked to heart attacks, there are four warning signs listed by the American Heart Association (AHA) as being crucial signs of an attack. These include:

Discomfort, pressure, squeezing, or fullness in the chest that continues numerous minutes or resolves then returns

aching or discomfort in the arms, neck, back, stomach, or jaw

sudden shortness of breath

Other signs can include a cold sweat, a sick or nauseated feeling, or being lightheaded.

Causes of Heart Attack

A heart attack befalls when one or more of your coronary arteries become blocked. Over time, a coronary artery can thin from the buildup of various substances, including cholesterol (atherosclerosis). This sign, known as coronary artery disease, causes most heart attacks.

During a heart attack, one of these signs can rupture and spill cholesterol and other ingredients into the blood circulation. A blood clot forms at the site of the rupture. If large enough, the clot can block the flow of blood through the coronary artery, ravenous the heart muscle of oxygen and nutrients (ischemia).

You might have a complete jam or partial. A complete blockage means you’ve had an ST elevation myocardial infarction (STEMI). A fractional blockage means you’ve had a non-ST elevation myocardial infarction (NSTEMI). Diagnostic steps and treatment might be diverse depending on which you’ve had.
