The symptoms of a heart attack are easy to identify in most cases. If someone has sudden pain in their chest area that spreads toward the left arm or back, this should immediately be looked at, as it could be serious. When it is an intermediate coronary syndrome, or angina, the situation is not as dangerous. However, it does require medical attention right away, because this is a clear sign that something is wrong. In this article we’ll be explaining all the symptoms of intermediate coronary syndrome for you.

First of all, you need to understand the symptoms of intermediate coronary syndrome. In this article we’ll describe the warning signs that you should keep in mind in order to prevent much more serious ones.

The first thing you should be clear on is what intermediate coronary syndrome is. Intermediate coronary syndrome is when something is wrong in the proper functioning of the cardiac muscle, called the myocardium. The poor functioning of this muscle causes strong pain in the chest. This is because the heart is not receiving the normal flow of blood.

Chest pain can happen frequently and sharply. This is a clear sign that there is a coronary artery disease in the making. As a result, you will require specialized treatment that can only be carried out by a cardiologist.

Symptoms of Intermediate Coronary Syndrome

  • Chest pain or malaise
  • A sharp pain in the arms, neck, jaw, shoulders, or back
  • Nausea
  • Fatigue
  • Difficulty breathing
  • Anxiety
  • Sweating
  • And, finally, dizziness

People that have suffered angina describe the feeling as a strong pressure in the chest area, as if they were lifting a very heavy weight.

Intermediate Coronary Syndrome symptoms in women

The symptoms of intermediate coronary syndrome can be very different in women because they don’t feel pressure or a feeling of weight. What they feel is a stabbing pain, nausea, difficulty breathing, or stomach pain. Because of this, it can be confused with other health problems. This can delay proper diagnosis, which is not at all good.

How serious can intermediate coronary syndrome be?

In reality, intermediate coronary syndrome can vary as regards seriousness and duration. You have to be aware of new or different symptoms, because it could be unstable angina/ intermediate coronary syndrome, which is much more dangerous than classic angina/intermediate coronary syndrome.

The most important thing is to go and see a specialist when one or more of these symptoms occurs. In these situations, it is a clear sign that your heart is not functioning like it should do. Consequently, you may need to undergo treatment in order to treat the problem in time.


  • Taking vasodilators, which control blood pressure and will make your blood vessels relax. As a result of this, your blood flow will increase.
  • Making a drastic change in your diet and implementing a diet rich in fruit, vegetables, whole grains, fish, and avoiding all kinds of fatty foods.
  • Doing moderate exercise, like taking walks and riding bikes. This type of exercise is a huge help in increasing blood flow to the heart.


Intermediate coronary syndrome can also happen when exercising and is alleviated when you rest a little bit. In contrast, a heart attack causes a much stronger pain. This can last more than five minutes and does not improve by resting.
