Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.

Heart Attack - Signs, Symptoms and Emergency Treatment

How many of us have heard about Extracorporeal Membrane Oxygenation (ECMO) before Tamil Nadu, Chief Minister late J Jayalalithaa was put on it for recovery? Hardly a handful. Patients who are placed on the device have 50-50 chance of survival and while it could not help the late Chief Minister, her condition put a spotlight on ECMO.

What is ECMO?
ECMO is a life support device that is put in place when a patient's heart and lungs stop functioning completely post a cardiac arrest. When the patient does not respond to Cardio Pulmonary Resuscitation (CPR), the patient is put on ECMO.

Function of ECMO
The core function of the device is to separate carbon dioxide from the blood and add oxygen into it. It takes the load off from heart and lungs, providing critical time to the body organs for its treatment and recovery.
Patients are only put on ECMO, if there is a chance that the condition can be reversed.

How does ECMO work?
The device drains blood from a vein, which is attached to an oxygenator machine. The machine then removes carbon dioxide from the blood and adds oxygen to it. Depending upon the condition of the patient, the warm blood is either pumped into the body with the help of the machine or is transferred back into the body through an artery.

How long a patient can be on ECMO?
After seven days of being put on ECMO,there are chances of patient getting an infection.
In case the patient contracts an infection, it is recommended to take the patient off ECMO support.

All About ECMO - Extracorporeal Membrane Oxygenation 

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

With recent lifestyle changes, more and more people, younger in age, are falling prey to heart attacks. While some silently suffer the attack during their sleep and never wake up, others have symptoms which they dismiss as acidity or muscular pain and ignore them. There are multiple media programs that are trying to create awareness about how to identify a heart attack. If done at the right time, there is a good chance that the person can be saved.

What is a Heart Attack?

The blood vessels gradually narrow, reducing the blood flow to the target organs. This reduces the efficiency of the target organ, and if this happens to be the heart, it is known as a heart attack. The area that should ideally receive blood does not, leading to its  death.  If the damage is not severe, it can be reversed. However, if this attack happens in one of the critical areas of the heart, it can even be fatal.

Symptoms To Watch For: Very few attacks happen suddenly. Most start slowly and progress, and if identified on time, a life can be saved. The episode takes about an hour, and if you are well-versed with the symptoms, it could help identify the condition correctly and save a life. Most people use antacids and muscle relaxants to ease the situation, which does provide immediate relief, but not a proper cure.

There is a central pain which is constant, nagging, and has a squeezing like sensation. This causes discomfort and most often, this pain is in the center of the chest area, which lasts for just a few minutes. Sometimes the pain can go and come back. This pain radiates down into the arm, up into the neck area, and also into the jaw and is almost always indicative of a heart attack.

With chest pain, there is always shortness of breath which the person will experience. This is due to reduced oxygen levels in the body.

Associated symptoms include fatigue, exhaustion, nausea, dizziness, light-headedness.

There is almost always profused sweating where the person breaks into a cold sweat.

If the attack happens during sleep, the person may be snoring and may feel, as if something is choking his airway.

Due to reduced return of blood from the peripheral organs, there could be swelling of the feet and ankles.

If there is irregular heart beat (palpitations) very often, talk to your doctor about it.

When you suspect a person of having a heart attack, check for these signs. Very often, a heart attack is detectable and can be managed with timely intervention.

Signs Of A Heart Attack

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?

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.
