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

Your heart is the most important and vital organ of all and regulates the flow of heart to all parts of the body. Thus, the valves and the arteries which take the blood to your heart are also an important component in ensuring that the circulation is constant. Thus, any hindrance to this process will put a lot of pressure on your heart and lead to more serious problems in the long run. Coronary artery disease is one such problem and can seriously put the health of your heart at risk.

What is coronary heart disease?
Coronary arteries are very important blood vessels, which carry nutrients, blood and oxygen to your heart. If the level of bad cholesterol is high in your blood, it will start leaving deposits on the walls of the arteries which are commonly known as plaque. This plaque will start building up over time causing blockage of the arteries and disrupting proper blood flow. Excessive build up of the plaque may then rupture the lining of the plaque. This will then induce blood clotting and further prevent the normal flow of blood.

Symptoms
Primary symptoms may include

Shortness of breath: This may occur while you are exercising or performing activities which are mildly exerting.
Heart beats very hard and fast: Your heart may beat very hard and fast, especially when doing everyday activities such as climbing stairs or walking for a prolonged distance.
Angina or chest pain: You may experience pain in your chest as if someone was pressing against it with a lot of force. Angina is also triggered due to stressful activities or even emotional stress. It usually occurs on the left or the middle of the chest and may even be felt in the back, arms, and neck.
Heart attack: Heart attacks are the most common and the most serious complications of coronary heart disease. You would feel extreme pain, akin to crushing on your chest, shoulder, or arm. It may even be accompanied by jaw pain, and sweatiness.
Treatment
Non invasive forms of treatment are always preferable rather than invasive surgeries or procedures to treat coronary heart disease, especially where the risk of serious complications such as heart attack are still on the lower side. Some of the treatments used for coronary heart disease are as follows:

Making lifestyle changes: Quit smoking, reduce alcohol consumption along with consumption of regulated diet will automatically start cleaning plaque that has built up within the arteries. Losing weight also tends to help.
Medications: Special medications can take care of cases wherein the deposits are still lesser and the plaque buildup can be removed without the requirement of extensive surgery. Anti-cholesterol medications are one example of this.
Surgical procedures: These are usually employed when the blockage is severe and cannot be corrected by the conventional methods mentioned above. Some of the procedures are angioplasty, stent replacement, as well as coronary artery bypass surgery.

Coronary Artery Disease -  Know the Primary Signs!

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?

Angioplasty is the procedure of opening a coronary artery blockage with the help of wire balloon and stent. This procedure is done to open the blocked coronary arteries if they are causing symptoms or acute heart attacks.

HOW IT IS DONE?

The procedure is usually done in local anaesthesia. A wrist artery (radial) or a groin artery (femoral) is used to gain access to the coronary artery as is done in angiography. A hollow tube called a catheter is passed upto heart artery and through this, a guidewire is passed across the blockage and over this wire balloon is passed and blockage dilated.

After this balloon is removed and the metallic stent is passed over this wire. The stent is then inflated and it takes its shape of the hollow tube so that the flow in the coronary artery is restored.

WHAT ARE INDICATIONS OF ANGIOPLASTY AND STENTING:

An acute Heart attack is the most definite indication of angioplasty and stenting. At the time of the heart attack, there is an urgent need to restore the blood flow of block coronary artery which is usually not possible with medicines alone. Angioplasty is the most effective and definite way of opening the artery urgently in such situation.

SHOULD ALL BLOCKAGES BE OPENED UP BY ANGIOPLASTY AND STENTING?

NO, all blockages do not warrant this procedure. There is some amount of risk involved in the angioplasty procedure itself. When the risk of blockage is considered more than the risk of opening the artery then the procedure is indicated. Patients who are doing good on medicines may be followed up without angioplasty.

All About Angioplasty!

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.
