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.

Ways to identify and treat Angina pain

Angina or angina pectoris is the pain, discomfort or tightness in the chest that occurs when the blood flow to the heart muscle cells is not enough to meet its energy needs. It is not a disease itself but rather a symptom of the coronary heart disease.

What are the different types of angina?

1. Stable angina: It is the commonest form of angina. It can be triggered by stress or physical activity and usually only lasts a few minutes.

2. Unstable angina: It happens when you're resting or aren't very active. The pain is strong and long lasting, and may keep recurring. It may be a signal of an impending heart attack.

3. Variant angina: This might take place when you're asleep or at rest. This sudden tightening or narrowing of the heart's arteries causes a lot of pain.

How u know what your are experiencing is an angina pain?

You might be having angina pain if you suffer from one or more of these symptoms:

- Chest pain
- Heartburn
- Breathlessness
- Nausea
- Dizziness
- Restlessness
- Fatigue
- Pain in your arm, neck, jaw and back
- Numbness or loss of feeling in your arms, shoulders or wrists

Immediate Relief from Angina

If previously advised by a certified doctor, patients can take antiplatelet medicines which are blood thinners and prevent unstable angina. Final treatments include angioplasty (repair of a blocked blood vessel through surgery), insertion of a coronary artery stent (a tube that is used to treat weakened arteries) or a heart bypass surgery for serious complications.



Ways to Identify and Treat ANGINA PAIN?

The new epidemic that has taken the world by storm is obesity. The proportion of obese people is increasing and the age of onset of obesity is decreasing gradually.

There is an optimal weight for a given height of a person. Obesity is when a person's weight is 20% more than the optimal weight. It brings with it a host of other health conditions, as it impairs the body s overall functioning.

Diabetes 2: In a normal person, food gets broken down into glucose to provide the required energy for the body using insulin. The body s inability to produce sufficient insulin to convert the excessive amount of sugar in the body leads to diabetes. Growing to be a leading cause of early death, diabetes brings with it a host of complications affecting almost all systems and parts of the body including stroke, kidney disease, blindness, and death. Diabetes and obesity have a direct correlation and can be prevented and managed by eating a balanced diet, losing weight, exercising, and having a healthy lifestyle.

Heart problems: An increased BMI also ups the risk for coronary heart disease (CHD), where the blood vessels are narrowed due to constant accumulation of fat in their inner walls. This gradually reduces the blood flow through these and may when complete cut-off happens, it could result in heart attack or stroke, affecting the heart or the brain. There could also be cases where the heart fails to pump sufficient blood to the rest of the body, affecting their effective functioning. Obese people also have a higher blood pressure than people who maintain a good BMI.

Breathing problems: One of the main causes of labored breathing is excessive weight. The condition called sleep apnea which is sudden bouts of absence of breathing during sleep is very high in obesity. It can cause snoring, daytime sleepiness, increase the risk of heart disease and stroke. In people with sleep apnea, weight loss is one of the first and most recommended therapies. Asthma and general breathing disorders are also higher in obese people.

Abnormal body cholesterol: Obese people also tend to have abnormally higher levels of body fat, especially the bad cholesterol, which again leads to coronary disease. It is a vicious cycle with one leading to the other and aggravating the other.

Osteoarthritis: Added weight leads to pressure on the hips, knees and lower back. There is added wear and tear and pain, which further limits movement.

Cancer: Some cancers, of the colon, endometrium, kidney, pancreas, gallbladder, breast and esophagus are more prevalent in obese people.

These are just some, there are more. The best way to avoid all these is to watch your weight.

Obesity - How It Increases Your Risk of Different Diseases?

An estimated of 10 percent or more children snore for more than 1 night. Snoring results from the obstruction of breath when the air makes its way through the mouth. The air passage of the throat through which the air goes in and out causes the tissue to vibrate causing snore. The sound of the snore totally depends on the amount of air passing through the mouth and the frequency at which the throat is vibrating. Children above the age of three years tend to snore when they are deep in sleep.

Primary and secondary snoring:
Children who are otherwise healthy should not have a snoring problem unless there is some health disorder. However, if loud snoring is observed in otherwise a perfectly healthy kid, seeking medical help is a wise thing to do. In general, primary snoring is defined as a condition which is not associated with other sleep-related disorders such as lung disorder, OASS, inability to sleep for a longer duration etc.

Other possibilities:
It is estimated that close to three percent of the children suffers from breathing problem while sleeping. OSAS is a condition which is characterised by pauses in breathing and gasps along with loud snores. There could be instances where a kids  muscle relaxes way too much obstructing the air to pass through. The body and the brain are both alerted at this stage. As soon as the brain sends a signal, the body wakes up. Thus, most kids suffering from this disorder are not able to sleep well and tend to feel tired throughout the day.

Common causes of sleep apnea:
Sleep apena is a major cause of snoring. It can be caused because of allergies, obesity, GERD etc. In children sleep, apnea can also be caused by tonsil. Since the tonsil size of children less than 7 years of age tends to be bigger than adult individuals, it causes snoring related problem. Swollen tonsils not only obstruct air but creates other health related problems as well.

Symptoms of sleep apnea during the day and night:

Loud snore
Snorts, gasps, pauses during sleep
Heavy sweat during sleep
Social and behavioural problems
Failure to get up in the morning
A nasal voice
Easily irritated, cranky and aggressive
Relief measure:
The first thing a that a doctor does is a physical exam followed by observing the symptoms of a kid. Primary snorting can be addressed by physical exercise, counselling and breathing exercise. Problems related to apnea are addressed through medicine, counselling, and exercise. Certain dietary restrictions also needed to be followed during this time. However, apena is completely treatable within a certain time frame.

Mouth Breathing - What Can Cause It?

Dialysis is a very important and life-saving procedure. It is performed to replace kidney function in case of renal failure. Wastes and extra fluids in the blood are filtered out during this process. To be able to perform Dialysis, the connection between the patient s bloodstream and the equipment for performing Dialysis (dialyzer) outside the body is established. This connection is created through Dialysis Access Surgery. It is a type of Vascular Surgery which forms the vascular opening for access during Dialysis. Thus, Dialysis Access Surgery is the lifeline for the survival of the patient.

Types of Vascular Access for Dialysis- 
There are three types of Vascular Access for Dialysis: Arteriovenous (AV) Fistula, Arteriovenous (AV) Graft, and Venous Catheter.

  Arteriovenous (AV) fistula is a surgical connection of an artery to a vein. An AV fistula is usually placed in the upper arm or in the forearm. It causes extra blood to flow into vein making it grow large. A larger vein hence provides easy access to blood vessels. An AV fistula is preferred over other methods as it lasts longer than other methods of access and provides a good flow of blood. Moreover, it is less prone to infection and blood clots than other methods. Before an AV Surgery, a Vessel Mapping Test is sometimes performed for assessing the blood vessels most suitable for Dialysis. An AV fistula is performed under local anaesthesia and requires two to three months for maturation before hemodialysis. If it fails to mature, the procedure is repeated.

  Arteriovenous (AV) graft is performed when AV fistula fails to mature. It is hence the second most preferred choice for long-lasting access to vascular tissues for Dialysis. An AV graft is a looped plastic tube which establishes a connection between an artery and a vein. Like AV fistula, AV graft is also performed under local anaesthesia. It is slightly more difficult to maintain than an AV fistula.

  A venous catheter is used for short- term hemodialysis. It is a tube which is inserted into chest, neck, leg, or near groin for vascular access. After exiting the body, the tube splits into two halves. In the case where a renal disease has made quick progression leaving little or no time for the AV fistula or AV graft to mature, a venous catheter is used to establish the required vascular connection. This procedure is also performed under local anaesthesia. It is a tool for emergencies but is not suited for long- term use. It can cause narrow vein due to an infection,
scarring, or blood clot. If long- term venous catheter is used, it is tunnelled under the skin which has fewer problems associated with it and is more comfortable. 

How to Care for a Vascular Access?
  Get checked for infections and other problems before each hemodialysis session;
  Use the operated site for access only for the intended use;
  Always keep the access clean;
  Prevent cutting or bumping the access;
  Check for thrill/ vibration in the access and inform the doctor if any;
  Do not put pressure on the access site;
  Do not put blood pressure cuff around the access arm;
  Do not wear jewellery or tight-fitting garments over the site;
  Do not lift a weight.

Take Away-
Vascular Surgery for Dialysis is performed to provide vascular access for the procedure. AV fistula is the most preferred type followed by an AV graft. A venous catheter is recommended to be used only in case of an emergency when there is not much time left for the other two options to mature.

Vascular Surgery - Can It Help For Dialysis?

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.
