Coronary artery disease

What are the functions of the heart?

The heart is a muscle that pumps blood throughout your body. Blood contains oxygen and nutrients that require body to function properly. To be able to work the heart properly, continuous supply of oxygenated blood is required. Blood vessels supplying this blood to the heart are called coronary arteries. If these arteries become active or block, then the blood flow to the heart as a result, and this requires treatment.

What are the causes of coronary artery disease?

A fatty, wax-like deposit called plaque (blood fat, cholesterol, calcium and other substances) can be deposited in coronary arteries in a process called atherosclerosis. This accumulated substance can make your arteries narrower or frozen in your arteries, which reduces the supply of blood and oxygen in the heart. This process is called  (CAD).

Coronary artery disease or CAD is a major cause of death for both men and women.

What are the signs and symptoms of CAD?

Because coronary artery disease (stunted artery) develops over many years, so often the symptoms do not appear until severe hindrances and life threatens. When your heart is working harder than normal, symptoms can also be seen before, such as during exercise. But these symptoms can happen even when you are resting and no activity is happening.

The most common causes of low blood flow and oxygen in the heart include:
– Angina (chest pain) Many times the angina is mistaken for heartburn or indigestion, which can spread in the hands, shoulders, back and jaw. In some cases, if a coronary artery breaks completely, then a person may have a heart attack, which is also known as myocardial infarction.

– Flow of small breathless breath

– nausea

– swelling

Although the most common symptom of a heart attack is pain or pressure in the chest, women may have some symptoms that are not related to chest pain such as:

-Neck, jaw, shoulder and upper back pain

-Burning sensation in the upper part of the stomach or abdomen

-Beat less or irregular heart beat

-Unusual and without cause fatigue

-Nausea or vomiting

Diaphoresis or “cold sweat”

If you think you have symptoms of coronary artery disease, talk to your doctor. If you think that you can get a heart attack, get medical help immediately.

Who is at risk?

When your age increases, your arteries are tough and the plaque is likely to accumulate. But some risk factors, which include behavior, stages or habits, can accelerate the development of CAD. The more the risk factors will be, the more likely the CAD will be to develop.

Although some risk factors are not in your control, like your age and family history, but other factors can be controlled or removed, which reduces your risk. These include:

High cholesterol
High blood pressure
Obesity, and
Lack of workout (such as comfortable lifestyle)
Some types of radiation therapy in the chest
High LDL “bad” cholesterol and low HDL “good” cholesterol

Your doctor can help you with the choices of healthy diet choices, tobacco use, and level of activity and stress management.


If your doctor suspects that you have coronary artery disease, he / she can refer you to a chronicologist who specializes in heart, arteries and nerves problems.
During your diagnosis your doctor will ask about your symptoms, medical history and risk factors. Depending on this information, your doctor may ask you to get tested so that it can be seen how healthy your arteries are. The most common checks are:

Electrocardiogram (ECG)
Echocardiogram (echo)
Stress test
Nuclei Heart Scan / Nuclei Stacey Test
Electron Beam Computed Tomography (EBCT)
Magnetic Resonance Angiography (MRA)
Intracrocular ultrasound (IVUs)
Blood test
Whistle angiography
