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!

Automatic Implantable Cardioverter Defibrillator is an electronic device that is located in the chest of the patient suffering from arrhythmia. Arrhythmia is a condition which causes abnormal rhythm of heartbeat in the patients. It is a life-threatening condition. The device is located in the chest to correct the rhythm of a heartbeat.

AICD device works in two ways:

Firstly, it tries to correct the abnormal heartbeat rhythm and release high- speed heartbeat pace. This is called cardioversion. Patients with AICD generally do not feel the process.

However, if the effect of cardioversion is null then the device will give a mild electric shock to the patient's heart to correct arrhythmia and reset the rhythm.

This second method is called defibrillation. The patient can feel the defibrillation.

The modern-day AICD device is programmed to store the data about the patient s heart rhythm. Doctors use the programmed device which contains your condition and provides medically correct therapy.

Preparation for AICD Implantation

The patient is required to fast six hours before undergoing the surgery. On admission, prescribed medicine is given to the patient and the latest heart condition is measured by an ECG test. If the patient is on blood-thinning medication, then it will be stopped 24 hours before the surgery.

The procedure will be carried out by a cardiologist. The patient will remain under observation in the hospital for at least two days.

Procedure

The entire process of setting up the device in the chest of the patient takes about 2 hours. The patient is sedated, and the area below the collarbone is numbed for the operation. A small incision is made in the chest area. With the help of imaging techniques, cardiologist sets up the device in the chest. The device is then connected to the veins and the heart. After the surgery, the patient is kept under observation. Heart rate, blood pressure, and overall health condition are observed by the doctors to determine successful implantation of Automatic Implantable Cardioverter Defibrillator (AICD). Post Procedure After the successful recovery of the patient, doctors usually discharge the patient with AICD attached. The doctors give complete care instructions of the device along with health. Doctors also guide the patient through the list of activities that one can and cannot perform. AICD is a life-saving device. Hence, proper care and regular check-ups are recommended by the doctors. The regular check-up of the device is also essential since the device runs on a battery. The doctors also train the patient about the workings of the device. They will also explain about the mild shocks of the device one may receive to correct the arrhythmia. Before leaving, make sure the site of the surgery is dry and healing, and you do not have a fever for the past 24 hours.

AICD Implantation - Know Procedure Of It!

It is true that most people are aware of the fact that  angina  is a term which has something or the other to do with the heart. That being said, very few would be able to answer a question regarding what exactly it is, in a satisfactory manner. So would it not make sense to know more about it and become one of the few?

The term is derived from the ancient language of Latin and refers to a tightness that is felt or a squeezing of the chest. This happens when there is not enough oxygen-rich blood which is reaching the area of the heart muscle. While many people think that angina is a disease, it is actually not true to think that it is! As a matter of fact, it is a symptom of coronary artery disease. It is this disease which is the most common disease which affects the heart.

But why exactly does a person experience angina? Well, the lack of blood which is rich in oxygen occurs when it so happens that the coronary arteries become narrower than they normally should be. This generally happens due to the build-up of plaque. The condition in which this happens is known as atherosclerosis.

When it comes to the sort of people who are at a higher risk of developing angina, it can be said that those who smoke tobacco really do increase their risk, as do those who are overweight or obese and have other lifestyle diseases such as diabetes.

In order to avoid angina, the most important thing a person can possibly control is his or her lifestyle. In fact, a lot of the risk factors related to angina are attributable to the lifestyle a person chooses to lead. Cholesterol levels can be controlled if a person puts enough attention and effort in. Also, avoiding a lifestyle that is sedentary by exercise can not only help with cutting the risk of angina but also the risks of other conditions such as high blood pressure. It is ironic that high blood pressure is one of the potential signals of angina!

It is to be noted that while most people just call angina as it is, there are various types-

Stable angina is when the heart is working harder than usual and medicine helps improve this.

Unstable angina occurs even at rest and is unpredictable. It may also be a signal of a coming heart attack.

Variant and microvascular angina is relievable by medicine and is generally rare.

What Is Angina?

Neurosurgery mainly deals with treating of functional disorders that affect the nerves, brain and muscles through major or minor surgery. The field of neurosurgery makes use of advanced surgical procedures. The different techniques are used to treat brain tumors, trauma to the head, cerebral hemorrhages, spinal disc herniation, brain aneurysms and peripheral neuropathy.

Neurosurgery Treatment
The main aim of neurosurgery treatment in patients suffering from stoke is to prevent neurologic deterioration as well as the recurrence of stroke. The advancement in medical treatment has increased to a great extent, however the mortality and morbidity in stroke patients is very high. The second leading cause of death all over the world is stroke, and hence, through neurosurgery stroke can be managed. Each year in the U.S there are about 800,000 people who suffer from stroke which causes disability.

Symptoms of Stroke and its Effects
The main symptoms of stroke are not identified easily by people. However, the symptoms that are caused on delay of treatment include difficulty in speaking, weakness on one side of the body, drooping on one side of the face and difficulty in walking.

Stroke at times is life threatening and it is also referred to as brain attack and can occur at any time to an individual. It is caused when the flow of blood supply to the brain is cut off and oxygen is deprived to the brain cells. Brain dysfunction occurs due to the dead brain cells and hence some patients lose their memory and control over their muscle movement. The treatment of stroke in such cases includes a neurosurgery by a neurological specialist.

Types of Stroke
The abrupt interruption to the flow of blood that causes hindrance in the neurological function can be best treated if detected early and by accurate diagnosis by a neurosurgeon. There are 3 different types of stroke that can occur and these include Hemorrhagic stroke, Ischemic stroke and Transient ischemic attack. The Ischemic stroke mainly occurs when blood vessels that supply blood to the brain are blocked. It is a common form of stroke and its underlying cause is known as atherosclerosis. The main procedures that are used for treating ischemic stroke include tissue plasminogen activator and endovascular procedure.

In the tissue plasminogen activator procedure, the patient is given medicine intravenously. The blood flow to the affected area of the brain is improved when the blood clot dissolves through this method. The medication is given immediately after 3-4 hours on occurrence of the stroke symptoms. In the second procedure, a catheter is used, which is injected in the area of the obstructed blood vessel. The blood flow to the area is restored by the endovascular procedure. Even anticoagulants are given to thin the blood and prevent clogging.

Neurosurgery In Management Of Stroke!

Bradycardia is a condition which in basic terms means slow beating of the heart. In most cases, the typical rate is 60 to 100 beats in a minute when the person is at rest. In case your heart beats less than 60 times in a minute, then it is slower than normal. But a slow heart rate is not always a health concern even though sometimes it could indicate issues with of the heart.

What could bradycardia mean?
Some people with slow heart rate or bradycardia tend to be very fit, and they have no underlying health issues. Athletes and healthy young adults often have a heart rate lower than 60. But in others, bradycardia indicates that the natural pacemaker of the heart is not working well, or the electrical pathways have been disrupted. In severe forms of the problem, the heart may beat so slowly that it fails to pump adequate blood for meeting the needs of the body. This may show some symptoms and could be fatally dangerous.

What are the causes of bradycardia?
There are various causes of bradycardia, and some of them include:

Alterations in the heart which results from aging
Health conditions that slow down the electrical impulse through the heart. This may include electrolyte imbalance, low thyroid levels, and others.
Diseases which may disrupt the electrical system of the heart including heart attack, coronary artery disease, and myocarditis.
Certain medications that are used for treating heart problems like high blood pressure or hypertension, arrhythmia, and beta-blockers, and digoxin.
What are the symptoms of bradycardia?
When a person has very slow heart rate, he or she may experience lightheadedness or dizziness, feeling short of breath, having difficulties in doing normal activities or exercising, having chest pain, feeling tired and fatigued. In some cases, it is seen that the person may have palpitations, feeling confused, trouble in concentrating and fainting.

What s worse, some people don t have any symptoms at all, or their symptoms are so negligible that they think they are caused just because of aging. The best way to understand whether you have this problem is to take the pulse, and in case, it is slow or uneven, you must talk to a doctor.

How is bradycardia diagnosed and treated?
Bradycardia tends to come and go from time to time, and therefore, a standard EKG is not always able to detect it. A standard ambulatory electrocardiogram is used for detecting the condition, and sometimes, blood tests are also necessary.

The treatment of bradycardia is entirely dependent on the cause of the problem and its symptoms. It is worthy of mention here that in case the problem is not causing any symptoms, then they would not be treated under usual circumstances.

An Effective Guide To Bradycardia!

Postural Tachycardia Syndrome or POTS, what this condition entails is a sudden and abnormal increase in the heart beat of an individual, causing them difficulty in breathing, dizziness, and even blackouts.
There are some factors that can trigger the situation and stem the sudden rise in the heart beat. Meeting with a medical expert may help bring the situation under control.

What is Postural Tachycardia Syndrome?
Postural Tachycardia Syndrome or POTS is a cardiovascular condition that is caused due to the sudden shift from an upright position to a supine position or vice versa. It is this sudden increase in heartbeat of an individual that is referred to as Tachycardia.

The longer you overlook this condition, the bigger is the trouble you are putting your health in. This is when it becomes extremely important for you to get in touch with a medical expert, who can offer you perfect consultancy, diagnose the causes and also find a result for the same.

What Causes POTS?
According to medical specialists, there are some factors that this condition stems from and it all differs from one person to the other. Some of the most common causes of the condition are-

Joint Hypermobility Syndrome
Faulty Gene
Poisoning
Amyloidosis
Lupus
Diabetes
Sarcoidosis
Siogren s Syndrome
Cancer
Signs of Postural Tachycardia Syndrome:
There are multiple signs that indicate that an individual is stricken by Postural Tachycardia Syndrome. Some of the more common signs and symptoms include:

Orthostatic Hypotension: Orthostatic Hypotension refers to the sudden increase in the heart beat by at least 30 beats per minute, within or after 10 minutes of rising up from a sitting or lying down position. Though the condition increases the heart rate, it does not trigger any drop or rise in blood pressure. Certain medications used to diminish this effect often extend some side effects, such as lightheadedness, palpitation, difficulty to breath, discomfort in the chest, weakness, heaviness in the chest area, nausea, cognitive difficulties and also stain on the vision.
Effects in Response to Postural Change: Almost one-third of the people with Postural Tachycardia Syndrome are noticed to faint as a result of the increased heartbeat, almost 40 beats minutes, instead of the chance in postural position. Other symptoms under this head include a headache, migraine, disturbance in sleep, fatigue, acrocyanosis or blood pooling in feet, etc.
Ehlers- Danlos Syndrome (EDS): Sometimes POTS is found to coexist in an individual with other conditions, such as EDS. This condition makes an individual prone to dislocation of bones, greater laxity in skin, loose- clicking joints, chronic fatigue, reduced level of tolerance towards any exercise, etc. According to medical specialists, though these are common symptoms of POTS, there might also be other signs. These signs and symptoms differ from one person to the other.
When Should You Consult a Doctor?
The moment you experience a POTS attack or for that matter notice some of the symptoms of the condition, it is time for you to consult a medical expert. The doctor will give you valued consultation, as well as diagnose the condition properly, thus finding the best treatment and suitable medication for you.
