Coronary Artery Obstruction and Associated Health Risks

The arteries can harden due to aging, but there are many factors that can accelerate this process, such as tobacco use, a sedentary lifestyle or a poor diet which leads to being overweight.

The coronary arteries are responsible for transporting oxygen rich blood to the heart muscle. When these arteries become clogged, it produces what is known as coronary artery disease, which causes an inadequate supply of blood to reach the heart, making it an extremely harmful health problem.

If the arteries become completely blocked, it is possible that these areas of the heart will be damaged. In many cases the worst consequence is the death of the heart muscle, and most troubling of all is that this is now the disease that has become the leading cause of death in the world.

People suffering from blocked coronary arteries are at a high risk of having a heart attack or myocardial infarction. The disease affects both men and women, and in both cases the death rates are quite high.

What are the causes of heart disease?


The obstruction of the coronary arteries is mainly caused by the buildup of fatty and waxy deposits inside the arteries. These in turn are composed of cholesterol, calcium and other substances in the blood. In general, the main causes of coronary heart disease are:

  • Thickening of the artery walls that provide nourishment to the heart muscle.
  • Accumulation of fatty plaque within the coronary arteries.
  • Narrowing of the coronary arteries.
  • Blockage of blood flow due to a clot formed within the coronary arteries.
  • Inflammation of the coronary arteries.

The obstruction can occur in one or more coronary arteries, regardless of their location. Likewise, there are different degrees of severity. By preventing proper blood flow through the heart muscle, this disease can cause symptoms such as chest pain or shortness of breath, among others.

Symptoms of heart disease


One of the biggest complications with coronary artery blockage is that it usually develops over many years. This presents a high risk because in its early stages it does not show specific symptoms and they may be slow to manifest until the disease is well advanced and difficult to treat. The symptoms of coronary disease differ in each person and in each case, but in general those that suffer from it usually have the following symptoms:

  • Discomfort or chest pain (angina).
  • Difficulty breathing.
  • Edema or fluid retention in the feet.
  • Extreme tiredness and fatigue after exercise.
  • Pain in the arms or shoulders.
  • Excessive sweating.
  • Nausea.

Risk factors


As people age, in most cases there is usually a hardening of the arteries. However, there are certain risk factors that can accelerate this process or contribute to clogged arteries.

  • Gender: the male gender has a greater risk of heart attack compared to women.
  • Age: men are at a greater risk from age 45 on, while women increase their risk from 55 years on.
  • Genetic factors: if there is a family history of heart disease.
  • Obesity and overweight.
  • Leading a sedentary life.
  • Smoking.
  • Having high cholesterol.
  • Suffering from hypertension.
  • Suffering from diabetes.
  • Stress.
  • Excessive consumption of alcoholic drinks.
  • Excessive consumption of fatty foods, sugars, cholesterol and calories.
