Coronary Artery Disease - Symptoms and Causes

Coronary artery disease is the disease in which the major blood vessels (coronary arteries) that supply blood, nutrients and oxygen to your heart get damaged or disease stricken. It is mostly caused due to the coronary artery getting plagued or inflamed. The consequent reduction in blood flow to the heart causes the various symptoms of coronary artery disease like angina (chest pain), short breath etc.

Symptoms:

Here is a list of a few symptoms that help in identification of the coronary artery disease.

1. Angina

Pressure or tightness may be felt in or near the area of the chest that results in pain. It is mostly felt in the middle or left side of the chest.

2. Shortness of breath

Another symptom of coronary artery disease is short breath, fatigue and a feeling of exertion.

3. Heart attack

Complete blockage of the coronary artery results in a heart attack that is a prominent symptom of coronary artery disease. A person may feel heavy pressure in the chest, pain in the shoulder or arm, sweating etc. prior to getting a heart attack.

Causes:

Coronary artery disease occurs when damage or injury is done to the inner layer of the coronary artery. This damage causes plaque, which are deposits made of fat, cholesterol and other cellular waste materials to accumulate near the damaged area of the artery. This process is known as atherosclerosis.

The various causes that result in coronary artery damage are listed below.

- Smoking
- High blood pressure
- Diabetes
- High cholesterol
- Obesity
- High stress
- Physical inactivity

Knowing Coronary Artery Disease - Symptoms and Causes

The coronary arteries supply the heart with oxygen-enriched blood and nutrients. If these arteries become damaged or diseased; they could cause Coronary artery disease or CAD. Plaque deposits on the walls of the arteries are the most common cause of this disease. This plaque is usually the result of high cholesterol levels. As the plaque builds up, the passage of blood flow is reduced. This reduces the amount of blood that reaches the heart. In cases of a complete blockage, CAD can even cause a heart attack. Because of its slow progression, this disease is often not diagnosed until it reaches a dangerous stage. However, it can be prevented and treated if diagnosed in time.

In the early stages of CAD, symptoms are not very noticeable. Symptoms become visible only when blood flow to the heart reduces and the heart has to pump harder than normal. The most common symptoms experienced include:

Chest Pain: This is also referred to as angina. It may feel like a tightening of the chest or pressure on the chest as though someone is pressing against it. This type of chest pain may be triggered by emotional or physical stress. It is usually relieved within a few minutes of stopping the activity. Women may experience this pain as a sharp, fleeting pain in the back, arm or neck.
Breathlessness: When the heart does not receive enough blood, it has to work harder to pump blood through the body. This may be translated to breathlessness of shortness of breath when performing any type of physical activity. It can also cause extreme fatigue.
Heart Attack: A heart attack is the most severe symptom of coronary artery disease. This is caused by the complete blockage of a coronary artery. A heart attack can occur without any symptoms or be preceded by slight symptoms. The signs of an impending heart attack include pain in the chest and shoulder, shortness of breath and extreme sweating. The chest pain may also travel to the lower jaw. These symptoms are more pronounced in men as compared to women. Women have a higher tendency of experiencing atypical signs such as extreme fatigue.
Other symptoms that might indicate coronary artery disease are dizziness, nausea and an irregular heartbeat. The good news is that this disease can be prevented. Staying physically active, maintaining a healthy weight, reducing stress and eating a low fat and low salt diet can help reduce the risk of CAD.

Coronary Artery Disease (CAD) - What Are The Symptoms?

Coronary artery disease or CAD is the name given to the heart condition in which the major blood vessels that supply your heart with blood, oxygen and nutrients, also called coronary arteries, get blocked, damaged or diseased.

Blockages usually happen when cholesterol-containing deposits called plaque deposit in your arteries. Plaque narrows the lumen of your coronary artery which means your heart gets lesser and lesser oxygen and nutrients to function properly.
Inflammation is also to blame for coronary artery disease.
Common symptoms of CAD include

Angina or pain in the chest
Shortness of breath
If the blockage is complete, you can get a heart attack.
Common Diagnostic tests
When you go to a heart specialist, she will ask questions about your medical history and follow it up with a physical exam and order routine blood and diagnostic tests to confirm CAD like:

Electrocardiogram (ECG): An ECG records electrical signals as they travel through your heart revealing evidence of a previous heart attack or one that s happening. Holter monitoring is a type of ECG where you wear a portable monitor for 24 hours as you go about your normal daily activities. Abnormalities in the results suggest reduced blood flow to the heart signaling CAD.
Echocardiogram: This test uses sound waves to produce images of your heart. It helps your doctor determine whether all parts of your heart wall are contributing to your heart's pumping activity. If certain parts are moving weakly it can mean damage to muscle due to a heart attack or because of receiving too little oxygen- again signaling CAD.
Exercise Stress test: This test is done by making you do exercises like walking on a treadmill or riding a stationary bike during an ECG. Sometimes, medication to stimulate your heart may be used instead of exercise.
This again detects areas in your heart that receive less blood flow.

Cardiac catheterization or angiogram. A special dye is injected into your coronary arteries to observe blood flow through your heart in a test known as an angiogram.
The dye is sometimes also injected into the arteries through a long, thin, flexible tube called catheter that is threaded through an artery in your leg to the arteries in your heart. This procedure is called cardiac catheterization. This test is very good in diagnosing CAD as the dye outlines narrow spots and blockages on the X-ray images of your heart.
Heart scans. Computerized tomography or CT can help your doctor actually see calcium deposits in your arteries that can be narrowing your arteries. If a substantial amount of calcium deposits are found, coronary artery disease could be the reason.
MRI scans are also done to diagnose CAD.

Common Tests For Coronary Artery Disease!

An unhealthy diet is an absolute no in daily life to remain healthy, fit and without any disease. Unhealthy diets fail to give the body the correct amounts and varieties of proteins and nutrients for a maximum proper health.
Too many intakes of calories lead to an unhealthy diet, which also increases blood pressure. It leads to a very poor calorie ratio-to-nutrient that leads to gain weight and also leads to malnutrition along with various health problems. Unhealthy diets cause chronic disease, hypertension, cancer, diabetes, osteoporosis and cardiovascular disease.
Therefore, unhealthy eating habits should be avoided and strongly abandoned.

Why Avoid Unhealthy Diet?

It causes obesity. Increased intake of nutrient-dense foods like fruits, sugar, processed carbohydrates and animal fat leads to obesity.
Nutrient deficiency is another harmful effect of following an unhealthy diet.
Illness is another factor. Poor intake of nutrition leads to diseases like heart disease, diabetes, and cancer. Lack of calcium weakens the bones, lack of vitamin A and C suppress the body immune system leaving a person vulnerable to diseases.
Increases the risk of coronary artery disease as unhealthy diet contributes to building up of plaque in the coronary arteries which can cause heart attacks.
Coronary Heart Disease - A Serious Issue!
It is a disease which leads to plaque building inside the coronary arteries, which supply rich oxygen blood to the human heart muscle. Over time the plaques either hardened or get ruptured and hardened plaque restricts the coronary arteries, which reduce the oxygen flow to the heart. On the other hand, if the plaque is ruptured blood is formed on its surface which also narrows the coronary artery and restricts the blood flow. And if the blood flow is blocked or reduced, then it might lead to Angina and heart attacks leading to loss of life. Angina causes chest pain it can also cause pain in the neck, back or arms. It is a state where one gets a feeling of indigestion.

Outlook
Changes in lifestyle, eating habits, intake of medicines and its procedures helps to prevent this disease. These steps can also reduce the chances of health problems. Therefore, a proper healthy diet is a must in a person s routine because it serves as one of the links to coronary heart diseases. In order to live long, live healthily and live happily one needs to adopt a good eating habit, take care of the medicines they intake, certain input time of exercise, change the monotonous lifestyle to lessen down the chances of their occurrence. Adopting healthy food habits also enables the body to fight against diseases and infections, reducing the rate of illness. It also reduces stress and provides a good healthy and happy life.

Unhealthy Diet - How It Is Related With Coronory Heart Disease?

Coronary artery disease is characterized by accumulation of plaque in the coronary artery that chokes blood supply to the heart. This plaque buildup usually starts with cholesterol accumulation and gradually other particles such as calcium and lipoproteins get deposited as well. Over time, the plaque accumulates, making the blood vessels narrow and choking the supply of blood. In some cases, if the plaque ruptures, it may lead to formation of blood clots resulting in stroke.

The symptoms of coronary artery disease are:

1. Breathing difficulties: This disorder may lead to shortness of breath as the blood pumping mechanism of the heart is impaired; this usually results in fatigue and exertion. It is advised to avoid advanced cardio exercises such as the high intensity interval training.

2. Chest pain: Stress related activities may cause intense pressure or tightness in your chest, resulting in pain in the middle or left portion of your chest. If you discontinue the activity, the pain would usually subside. In some cases, you may feel the pain in the arm and the neck.

3. Heart attack: If the level of plaque accumulation is excessive, then it may result in a heart attack. It is characterized by breathing difficulties, pain, tightness in the chest and sweating. You may also experience pain in the neck and the jaw.

The causes of coronary artery disease are:
1. Smoking and alcohol consumption
2. Leading a sedentary lifestyle ups the risk of coronary artery disease
3. Hypertension
4. High cholesterol levels in the body
5. Blood sugar problems

Treatment
1. Get your blood pressure under control: If you suffer from high blood pressure, then it is recommended to get it under control to prevent coronary artery disease.
2. Quit smoking: If you are a habitual smoker, then it is time to nip the habit in the bud. Smoking is known to constrict blood vessels as it is a vasoconstrictor.
3. Eat healthy: Eat a well balanced diet consisting of vegetables and fruits so that your body receives the essential nutrients to function well.
4. Beat stress: You need to control your stress levels through exercise or meditation. Take time off work and do activities that make you happy.

Coronary Artery Disease: Causes and Treatment

If the blood flow between left ventricle and aorta is obstructed, it is known as Aortic Stenosis.
Aortic stenosis can occur in newborn, infants, children and adolescents. It is more common among boys than in girls.
Mild cases of this disorder do not need treatment. However, if a child has a severe case of aortic stenosis, then it requires treatment.

Aortic stenosis: Causes-

Blockage in the valve, mainly in the form of bicuspid valve stenosis (Aortic valve stenosis)
Muscular/fibrinous obstruction beneath the aortic valve (Subaortic stenosis)
Narrowing above the aortic valve in aorta itself (Supravalvular aortic stenosis)
Aortic valves regulate blood flow to the body parts. When aortic valve opens, it allows blood to go forward then it closed down so that blood will not come back to left ventricle.
However, if there is a problem with the aortic valve, it cannot open entirely and that restricts the passage of blood. The heart has to work extra hard to ensure that the entire volume of blood flow through the faulty valve.

Sometimes babies are born with deformed aortic valve in the form of bicuspid aortic valve that is prone for obstruction as compared to normal trileaflet aortic valve.

Aortic Stenosis: Symptoms-

Symptoms due to aortic stenos is depends on age of the child and its severity.
If occurs in newborn babies, it is generally severe in intensity and babies are generally in shock like state due to low cardiac output.
Infants are generally tired easily during feeding.
Children show signs of easy fatigue, chest pain, loss of consciousness and in late stages with shortness of breath.
Diagnosis of Aortic Stenosis-

Pre-natal testing like a fetal echocardiogram can reveal aortic stenosis if moderate to severe in intensity. That is why as soon as the baby is born, treatment is initiated.
Even if the child was not born with a problematic valve, this condition can arise a few years later.
For diagnosing this disease pediatric echocardiogram by pediatric cardiologist needs to be done from the chest of the child
Treatment of Aortic Stenosis-

If aortic stenosis is mild to moderate in intensity then we need to do follow-up of the child at regular intervals.
However, in severe aortic stenosis, treatment needs to be done
In valvular aortic stenosis, treatment of choice is by doing ballooning of aortic valve (Balloon aortic valvuloplasty, BAV) in any age group.

Balloon Aortic Valvuloplasty - This is not open-heart surgery. It is done in cardiac cath lab under fluoroscopic guidance by using vessels in thigh. We cross the valve with wire and catheters and we inflate a balloon across the stenosed aortic valve.

Open heart surgery: In subvalvular and supravalvular aortic stenosis, treatment is by open heart surgery.

Valve Replacement - An artificial valve or a donor valve is surgically attached at aortic valve location when valve is not amenable for ballooning. It is generally done in adolescent or adult patients.
Parents need to be alert and attentive to any physical discomfort that their child is suffering because that could be a symptom of aortic stenosis. The right treatment at the right time is necessary whenever required.
