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?

What is Palpitation?
Palpitation is a feeling of awareness of your own heart beat. It is usually described as heart rate being either too fast (racing), too slow or a sensation of missing a beat.

Types of palpitations?
Normal (Benign)
- These palpitations occur as a response to physical or mental stress like exercise, fever, pain, fear, anxiety etc. 
- They are harmless and settle on their own once the precipitating factors disappear. They do not require any medical treatment.

Abnormal
- These palpitations occur due to some underlying abnormality in either the structure of heart or the beating of heart. 
- These can be dangerous and at times life threatening. They may or may not settle on their own and require some medical treatment.

Warning signs that suggest palpitations are abnormal?
Palpitations are abnormal, if they are associated with chest heaviness, chest pain, uneasiness, sweating, weakness, giddiness, feeling of black out, fainting, nausea, vomiting, seizures. Palpitations are more likely to be abnormal in people who have some existing heart disease and these patients should report to their doctor at the earliest.

What to do during palpitations?
1. Stay calm. 
2. Call for help. If u are alone avoid driving, use a taxi or auto, go to your nearest hospital/doctor and try to get an ECG during the palpitations. If you are helping someone having palpitations, if they faint, call for help, start CPR if they remain unresponsive and take them to the nearest hospital. 

Which doctor can treat palpitations?
Doctors who specialise in the treatment of palpitations are called Electrophysiologists. They specialise in heart rhythm and are capable of performing a variety of complex tests to identify and treat different types of palpitations.

Which investigations are used to diagnose palpitations?
ECG: Taken during palpitations and when the patient is normal is a very helpful tool. 
Holter: Externally applied recorder, which continuously records heart rhythm for 24 hrs. 
ELR: Extended loop recorder, is like holter, but it records rhythm for longer durations. 
ILR:  Internal loop recorder is attached within the body for recording rhythm for long duration. 
EPS: Electrophysiology study, is the most sure shot test to diagnose, identify and treat 
Palpitations.

What is EPS?
EPS stands for Electrophysiology study. By this test a trained Electrophysiologist studies the conduction and formation system of heart beat, to understand the source, cause and type of palpitation. It is a simple and safe procedure of 2 to 3 hours and can be done as a day care procedure (by admitting the patient for a few hours in hospital, with discharge on same day).

It requires fasting for 4 hrs, some standard blood investigations and is done with local anaesthesia and if required it can be combined with treatment like ablation in the same sitting.In the procedure Electrophysiologist take catheters into your heart to study and stimulate the palpitations and understand them. Once found they can use various techniques to stop the palpitations, the techniques are called Ablation.

What are the treatment options available for palpitations?
There are many options depending upon the nature of palpitations and condition of the patient: 
- Drug therapy 
- Cardioversion where either a drug or electric shock is given to stop palpitations immediately. 

Ablations using many sophisticated computer softwares 
Device Therapy like ICD (Internal cardiac defibrillator) 
Combination of all the above therapies.

Your Electrophysiologist and you as a team can make a choice about the options that will be best for you.

Palpitations - Everything You Need to Know

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?

Your diet plays a major role in the health of your heart, so eating healthy should be somewhere on the top of the list for keeping your heart healthy as well. There are numerous heart disorders that occur due to unhealthy food patterns and consumption. Lifestyle factors are the major causes of heart disease, and diet occupies an almost compelling spot when lifestyle factors are taken into consideration. Here is a list of foods that keeps your heart healthy:

Salmon: Omega-3 fatty acids are very important for your heart to function optimally. Fishes such as salmon and sardines are rich in omega-3 fatty acids which lower the risk of heart diseases such as arrhythmia (irregular heartbeat) and atherosclerosis (accumulation of plaque in the arterial walls).

Oats: Like oats and milk for breakfast!? Congratulations! You are in luck; oatmeal has soluble fibers which help in lowering bad cholesterol levels. Just make sure that there is no added sugar in your oatmeal, as it will defeat the entire purpose.

Blueberries: Blueberries are rich in antioxidants that reduce the risks of heart attack and also decrease your blood pressure. So go ahead! Toss some blueberries in your oatmeal to get your daily dose of antioxidants which are such pre-requisites for supreme health.

Dark Chocolate: This will probably bring a smile to your lips. Dark chocolates contain polyphenols, a type of flavonoid, which is very good for your heart. Dark chocolate is known to reduce the risks of strokes and heart attacks. Watch the portion size as no matter what its benefits are, dark chocolates are still rich in calories.

Citrus Fruits: Citrus fruits such as lemons and Indian gooseberry are rich in compounds that lower cholesterol levels in the body. Tip   Start your day with a lemon juice and warm water. This betters your metabolism and also keeps your heart in fine shape.

Soy: Lo Behold Vegetarians! (and non-vegetarians as well). Soy is a protein rich food that is so good for your heart. It also contains heart-healthy fats and fibers that help bring down and normalize cholesterol levels.

Tomatoes: Tomatoes are rich in an antioxidant called  lycopene , which is very effective in getting rid of bad cholesterol. It thus helps in keeping your arteries healthy and reduces the risks of heart attacks.

Nuts: Nuts such as almonds and walnuts are rich in Vitamin E which helps in lowering bad cholesterol in the body. Avoid nuts that come with added salt.

Foods That Help You Maintain A Healthy Heart

Arrhythmia is a disorder which is characterized by improper and irregular heartbeats; be it too slow or too fast. This problem occurs when the electrical impulses that are used to regulate your heartbeat don t work in the correct manner. Your heart may beat irregularly, too slow or too fast.

Symptoms
Although this disorder does not yield many symptoms, a few noticeable symptoms of arrhythmia are slow heartbeat, or a racing heartbeat, chest pain, breathing difficulties and dizziness. Arrhythmia can lead to inefficient pumping by the heart, leading to bouts of fainting. A severe symptom of this disorder is ventricular fibrillation, wherein the ventricles tend to quiver instead of transporting blood. This symptom can cut off blood supply to the vital organs, which may lead to death.

Causes

Coronary artery disease: In this disease, arteries of the heart can get blocked, leading to irregular heart beat and impaired heart functioning.
A heart attack: An ongoing heart attack usually leads to irregular heartbeats.
High blood pressure: High blood pressure problems make you more vulnerable to this condition.
Impaired functioning of the thyroid glands: An overactive or underactive thyroid gland can lead to heart arrhythmia.
Excessive smoking and alcohol consumption: These habits can cause problems with the blood vessels in the body, thus increasing risks of this particular condition as well as other cardio-vascular diseases.
Stress: Too much stress can lead to high blood pressure; that is again linked to heart arrhythmia.
Treatment
Mild symptoms of arrhythmia do not require treatment. However, complications resulting from it warrant treatment. The various treatment options for this condition are:

Pacemaker: A pacemaker is a device that is used to regulate your heart rhythms. It is placed in the body by a surgical procedure and an insulated wire is put, connecting the heart to the pacemaker. In case of an irregular heartbeat, the pacemaker sends out impulses to correct the improper heartbeat.
Implantable cardioverter-defibrillator: This device is used to prevent a dangerous symptom of heart arrhythmia, a symptom wherein the ventricle quivers. It is similar to a pacemaker as it is also placed near the collarbone. In case it detects an abnormal rhythm, it sends out shocks to reset the heart rhythm.
Maze procedure: This is a surgical procedure wherein incisions are made on the upper heart tissue to create a scar tissue. Scar tissues act as insulators to prevent stray impulses.
Alternative therapies: Alternative procedures such as yoga and meditation can help remedy the disorder.
