Coronary arteries diseases
Symptoms and causes
Diagnosis and treatment of Coronary Arteries
Coronary arteries diseases occurs when the major blood vessels that supply your heart with blood, oxygen, and nutrients (coronary arteries) become damaged or sick. The deposits containing cholesterol (plaques) in the arteries and infections are usually the cause of coronary artery disease.
When plaques accumulate, the coronary arteries narrow; This reduces blood flow to your heart. Ultimately, decreased blood flow may cause chest pain (angina), shortness of breath, or other signs and symptoms of coronary disease. A complete blockage can cause a heart attack.
Since coronary artery disease often occurs over decades, you may not notice any problem until there is a significant blockage or heart attack. But there is a lot you can do to prevent and treat coronary artery disease. A healthy lifestyle can have a considerable impact.
Symptoms of Cornary Artries
If your coronary arteries are narrowed, they will not be able to supply the heart with sufficient oxygen-rich blood – especially when the heart is accelerating, for example, during exercise. First, low blood flow does not cause any of the symptoms of coronary artery disease. Constant accumulation of deposits in your coronary arteries, however, signs and symptoms of coronary artery disease may develop, including the following:
Chest pain (angina).
You may feel pressure or heaviness in the chest as if someone were sitting on your chest. This pain referred to as angina, occurs in the middle or left side of the chest. Angina generally appears through physical or emotional stress.
The pain sometimes ends within minutes after the strenuous activity stops. In some people, especially women, the pain may be transient or sharp in the neck, arm, or back.
Shortness of breath.
If the heart does not pump enough blood to meet your body’s needs, your shortness of breath may develop into fatigue and fatigue.
A blockage of the entire coronary artery causes a heart attack. Signs and symptoms of a classic heart attack include a lot of pressure on your chest and pain in your shoulder or arm, sometimes accompanied by shortness of breath and sweating.
Women somewhat, and less likely, suffer from signs and symptoms of a heart attack, such as neck or jaw pain. Sometimes a heart attack occurs without any apparent signs or symptoms.

When to see a doctor?
If a heart attack is suspected, you should call your local emergency number immediately. If you do not have access to emergency medical services, have someone take you to the nearest hospital. Drive only as a last resort.
If there are risk factors for coronary artery disease, such as high blood pressure, high cholesterol, use of dependency or diabetes, or a family history very full of heart disease or obesity, you should speak to a doctor. The doctor may examine the patient to see the condition, especially if he has signs or symptoms of narrowed arteries.
Coronary artery disease is believed to start when the inner layer of it is injured or damaged, which may happen early in childhood. The damage may be caused by many factors, including:
Diabetes or insulin resistance
Once the inner wall of the artery has been damaged, fatty deposits (plaques) consisting of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the plaque surface is broken or torn, the blood cells called platelets will clump on-site in an attempt to repair the artery. This lump can block the artery, leading to a heart attack.
Risk factors for coronary artery disease include:
Only getting older increases your risk of arterial damage and stenosis.
Men are generally more susceptible to coronary artery disease—however, the risk increases in postmenopausal women.
The family history of heart disease is associated with an increased risk of coronary heart disease, especially if a relative has heart disease at an early age. You are more at risk if your father or brother is diagnosed with heart disease before the age of 55 or if your mother or sister is diagnosed before the age of 65.
Smokers are more likely to develop heart disease. Exposure to secondhand smoke also increases your risk of coronary artery disease.
Uncontrolled high blood pressure may lead to atherosclerosis and stiffness; This causes the narrowing of the channel through which the blood passes.
High levels of cholesterol in the blood
It may increase the risk of plaque formation and atherosclerosis. High cholesterol may be caused by a high level of low-density lipoprotein (LDL) cholesterol, known as “bad” cholesterol. HDL cholesterol, known as “good” cholesterol, also contributes to atherosclerosis.
Diabetes is associated with an increased risk of coronary artery disease. Type 2 diabetes and coronary artery disease share the same risk factors as obesity and high blood pressure.
Being overweight or obese
Excess weight usually worsens other risk factors.
Lack of physical activity. Lack of exercise is also associated with coronary artery disease and its sales his risk factors.
In your life, unexplained pressure can damage your arteries, as well as worsen other risk factors for coronary artery disease.
Eating more food that contains large amounts of saturated fats, trans fats, salt, and sugar may increase your risk of coronary artery disease.
Risk factors usually occur in groups and may be built on one another, such as obesity that leads to type 2 diabetes and high blood pressure. When a group of specific risk factors group together, you may be more likely to have coronary disease.
For example, metabolic syndrome – a group of conditions that include high blood pressure, high triglyceride levels, low HDL or good cholesterol, high insulin levels, and increased fat around the waist – increases the risk of coronary artery disease.
Sometimes coronary artery disease is produced without any typical risk factors. Researchers are studying other possible factors, including the following:

This disorder causes frequent stops and starts breathing during sleep. The sudden drop in oxygen levels in the blood that occurs during sleep apnea increases blood pressure, and strains the cardiovascular system; This can lead to coronary artery disease.
Highly sensitive C-reactive protein
High-sensitivity C-reactive protein (hs-CRP) is a natural protein that appears in high quantities when there is inflammation in the body. One of the top risk factors for high-sensitive C-reactive protein (hs-CRP) is heart disease. It is believed that with coronary arteries narrowing, a higher amount of highly sensitive C-reactive protein (hs-CRP) will be present in the blood.
Triglycerides are one of the types of fats (fats) found in the blood. High levels may increase the risk of coronary artery disease, especially in women.
Homocysteine is a DNA that the body uses to build protein and to build and maintain tissue. But high levels of homocysteine increase your risk of coronary artery disease.

This condition may occur in women during pregnancy. This causes high blood pressure and increased protein in the urine. It may lead to an increased risk of heart disease later.
Drinking too much alcohol can damage the heart muscle. It may also worsen other risk factors that cause coronary artery disease.
Autoimmune diseases, cases of rheumatoid arthritis, and lupus (and other matters of rheumatoid inflammation) increase the risk of atherosclerosis.
Coronary artery disease can lead to:
Chest pain (angina)
When coronary arteries narrow, the heart may not get enough blood when demand increases, especially during physical activity. This can lead to chest pain (angina) or shortness of breath.
If cholesterol plaques are torn, and blood clots form, complete blockage of the heart artery can lead to a heart attack. Low blood flow to the heart can damage the heart muscle. The level of damage depends to some extent on the level of speed of treatment.
If some parts of the heart become chronically deprived of oxygen and nutrients due to low blood flow, or if the heart is damaged by a heart attack, the heart may become very weak as it is unable to pump sufficient blood that meets the body’s needs. This condition is known as heart failure.
Abnormal heart rhythms (arrhythmias)
Inappropriate blood supply to the heart or damage to the heart tissue can interfere with the heart’s electrical impulses, causing abnormal heart rhythms.
The same lifestyle habits that may help to treat coronary artery disease may also help prevent it from the start. Having a healthy lifestyle can help keep arteries secure and plaque-free. To improve heart health, you must do the following:
- Quit Smoking
- Control conditions such as high blood pressure, high cholesterol, and diabetes
- Maintaining physical activity
- Eat a low-fat, low-salt diet rich in fruits, vegetables, and whole grains
- Maintain a healthy weight
- Reduced and controlled pressure.
