We all are aware of heart attacks and cardiac arrest but we have a null idea about How to treat sudden cardiac arrest?

Many cardiologists gave the below-detailed explanation on cardiac arrest. We all often confuse and sometimes misconception occurs between cardiac arrest and heart attack. We all imagined these both are just synonyms and interchange the words. 

So, the truth is, cardiac arrest is different from the heart attack as said by the best cardiologist in Hyderabad India.

Check out the total detailed information on cardiac arrest and heart attack which are categorized accordingly as per the experts.

Difference between Heart Attack and Cardiac Arrest:

Heart Attack: Heart attack generally occurs when blood with oxygen content stops to flow in one section of the heart and blocks the artery from blood flow. If this artery blockage is not cleared quickly it may lead to the death of the artery which damages the body.

If the treatment is not received in short spam then the circumstances will be worse and may lead to death. Many symptoms will start showing before hours, days or weeks.

Cardiac Arrest: Usually, cardiac arrest occurs without any warnings. It happens because of the irregular electrical signals in the heart which leads to an irregular heartbeat which is known as arrhythmia. Because of this action heart cannot pump blood to the brain and other parts of the body.

This leads to unconsciousness and pulse rate breaks down and a person can die in minutes when the treatment is not provided immediately.

Cardiac arrest or Cardiac arrhythmia

Is there any link between heart attack and cardiac arrest?

According to a best pediatric cardiologist in Hyderabad, there is a major link between both heart attack and cardiac arrest. When a person is affected with the heart attack there are fewer chances of getting a cardiac arrest or they may not get but when a person is affected with cardiac arrest, it very commonly directs to a heart attack. The cardiac arrest also happens because of heart diseases like arrhythmias, heart failure, heart muscle thickness, etc.

Can cardiac attack or heart attack lead to death?

Yes, Cardiac arrest and Heart attack  both can lead to death if there is no proper treatment provided within the very short span of time after it occurs. There are even possible chances to recover from cardiac arrest or heart attacks only when the treatment is started within a few minutes.

Signs of cardiac arrest:

  • Does he collapse without any prior warning signs?
  • A person faints and losses his consciousness suddenly.
  • Check whether the person has breathing or not.
  • Check -heartbeat and try to know whether the heart rhythm is slow or fast or normal.
  • Check for response by touching him such as tapping on shoulders or back.
  • Some people will have little dizziness and light headache before they faint.
  • People may also suffer from nausea, vomiting before getting the cardiac arrest.
  • Few may also get chest pain seconds before they collapse.

Causes of Sudden cardiac arrest:

There are many diseases and general causes which lead to cardiac arrest which are specified by the best cardiologist in Kukatpally Hyderabad in which few of them are listed below.

Diseases which are the causes of Cardiac arrest:

There are several causes for cardiac arrest because of a change in lifestyle, food and human body variations. These causes are developed from the below-listed diseases which are related to heart and others. Few of the important causes are listed below.

  1. Heart Attack: Person affected with heart attack often may suffer from cardiac arrest. A heart attack occurs due to many reasons.
  2. Coronary Artery Disease: It occurs when the arteries are blocked with bad cholesterol, blood and reduces blood flow. This usually may lead to cardiac arrest.
  3. Electrical Wiring: The electrical system in the heart causes a different issue which ends up with cardiac arrest in many people. This generally causes because of the irregular heart rhythms.
  4. Hypertrophic cardiomyopathy (HCM): One in 500 people are affected with HCM and there are various reasons behind this disease such as high blood pressurediabetes, sometimes thyroid. This is the common cardiac arrest reason in many young people.
  5. Pulmonary embolism: This appears due to the sudden blockage of blood in the pulmonary arteries in the lungs. If the blood clot is very heavy it will stop the blood flow from the heart and sudden cardiac arrest occurs.
  6. An aortic aneurysm: A balloon is formed in the arteries which affect blood flow to the heart internally and causes cardiac arrest because of a lack of healthy heart functionality.
  7. Aortic dissection: This occurs when the aorta is split in its inner layer and there is a rapid rise of blood in the inner layer and separates the middle layer and inner layer. This is the less common cause of cardiac arrest.
  8. Cardiomyopathy: This occurs when the heart muscles stretch and enlarge in the internal heart walls which may reduce blood flow and damages heart tissues and this leads to cardiac arrest.
  9. Valvular heart disease: Leakage or narrow of heart valves will damage heart functionality and the heart chambers become week. All these are the reasons for cardiac arrest.
  10. Congenital heart disease: This disease occurs from birth. If a child or adolescent is suffered from cardiac arrest then this congenital heart disease is the major reason behind it. It has higher chances of affecting adults when they had congenital heart surgery.

General causes of sudden cardiac arrest:

Not only diseases but also the below listed general causes will direct to cardiac arrest.

  1. Physical Stress: Certain physical stress will cause an electrical failure in the heart which leads to cardiac arrest. Few of them are very low blood levels, insufficient oxygen circulation, an overdose of physical activities and other forms of physical stress will effects heart.
  2. Inherited disorder: A tendency to have heart diseases because of genital disease structure such as arrhythmias in the family. It inherits from parents or grandparents to a child. Members of the heart disease affected family are higher at risk.
  3. Structural change in the heart: There are many cases where the structure of the heart such sizes of the heart affects heart functionality and is the common cause of cardiac arrest. An enlarged heart will lead to many heart diseases. Heart infections are the major cause of structural change.
  4. Demographics: Cardiac arrest occurs irrespective of demographics such as age, sex, and race. It affects a different group of people irrespective of locations.

Cardiac Arrest in Children:

Among many infants and children, cardiac arrest is caused commonly due to the respiratory progression failure, shock or both of them. The main two diseases through which cardiac arrest occurs in children are:

  • Pediatric cardiac arrest: This happens very rarely but it comes without any warning signs. A sudden collapse will be the result of this type.
  • Arrhythmia: ventricular fibrillation is the reason behind this cardiac arrest. It comes with warning signs and there are very fewer chances of recovering life.

To save the lives in this dangerous situation generally, Cardiologist chooses to start the treatment by using both compressions and ventilation in CPR as this increases the chances of survival, especially in infants and children.

Sudden cardiac arrest in young people:

Cardiac arrest is very rarely seen in young people. Diseases like hypertrophic cardiomyopathy, coronary arteries are the causes of sudden cardiac arrest. Athletics are the group of people who are affected more by cardiac arrest.

How to treat sudden cardiac arrest?

Cardiac arrest is treated using different phenomenal and surgeries depending upon the seriousness of the diseases and the various types are listed below.

Sudden Cardiac Arrest Treatment:

External Defibrillators: It measures the electrical activity in the heart and if necessary it starts shock therapy if the heart rhythm starts very fast. Most of the best Interventional cardiologist in Hyderabad emergency teams take out this treatment outside the hospital to the needed place for quick therapy.

Cardiopulmonary resuscitation (CPR): CPR acts as a vital role in providing the continuous flow of oxygen-rich blood into the important organs of the body until next level treatment care starts. It works very well and The American Heart Association recommended very strongly to everyone.

Long-term Treatments:

Implantable Cardioverter Defibrillator (ICD): This is a very small device implanted under the skin either in the abdomen or chest area. It acts same as the external defibrillators but monitors the heart rhythms automatically and provides the treatment at the needed time. This protects from cardiac arrest.

Coronary angioplasty: Coronary angioplasty process involves clearing the blocked coronary arteries and allows smooth blood flow to the heart. This reduces the risk of arrhythmias. For this process, doctors insert a long tube in your leg part and pass through an artery in the heart and clear the blockage.

Coronary bypass surgery: It is also called as bypass surgery or coronary artery bypass grafting. This surgery sews veins and artery at the place of blockage and restores the blood flow to the heart. This helps in proper blood flow to the heart and other body parts and also controls the heart rhythms.

Radiofrequency catheter ablation: It is used to block abnormal electrical supply in the heart and one or many catheters are inserted into the inner heart blood vessels. These help in controlling cardiac arrest and other heart diseases.

Corrective heart surgery: Heart surgery is performed because of valve faulty, congenital heart, heart muscle tissue disease. This controls regular blood flow in the body and reduces the risk of cardiac arrest and other heart-related problems.

Cardiac Rehabilitation: Rehab is the place where you will gain more activeness, healthy life, proper lifestyle, energetic and positive attitude towards life, in short, you will change the perspective of seeing life and start working towards the betterment only with the help of their teaching skills. Cardiac rehab makes the heart stronger and healthier with their treatment.

Cardiac arrest treatment in hospital:

A person affected by cardiac arrest are initially admitted to the hospital where they will undergo the further treatment process. The process is listed below.

  • A medical team will keep you under observation and check your heart functionality from time to time.
  • Meanwhile, doctors will try to find out the cause of the cardiac arrest and starts with the initial treatment.
  • Medication is provided by the hospital staff to control the heart irregular rhythms and try to reduce the risk of getting a sudden cardiac arrest.
  • If a person is diagnosed with coronary artery disease then they have the treatment of angioplasty or coronary artery bypass surgery. All these procedures will help in regulating the proper flow of blood in the body and allow the regular blood flow to the heart.
  • Generally, people diagnosed with Sudden Cardiac Arrest (SCA) get Implantable cardioverter defibrillator (ICD) which contains a small chip and it is placed in the skin by the surgery. The detailed explanation is given above.

Emergency Treatment of Cardiac Arrest:

If a known person is suffered from a cardiac arrest here are the basic steps to be followed immediately without any delay to save that person's life. This below process can also use for the Cardiac arrest treatment at home. Do remember all these below-listed steps and act wisely and immediately whenever there is a need.

  • Check for breathing.
  • Call for an ambulance and do not fear of anything as you are saving a person's life.
  • If you have Defibrillators, use it to stabilize heart rhythms and give shock treatment to pump the heart.
  • If you do not have defibrillators and not a trained professional to handle the situation. Start pushing down hard with all the force at the center of the chest area at least for 30 times to pump the heart and make the blood flow.
  • If there is no breath, give the person a minimum of 2 breathings by yourself.
  • This procedure is to be performed in minutes without any delay or waiting for something to happen.
  • Always remember you are the lifesaver for that person, never be too late in taking initiative for such causes.

Diagnosis Tests of Cardiac Arrest:

  1. Echocardiogram: It is also known as Echocardiography or echo. It uses sound waves to make a picture of your heart to know its status. This test shows the proper functionality of the heart along with its chambers and valves working status. It also gives the evidence for the exact size and shape of the heart.
  2. Electrocardiogram (ECG): ECG test checks the heart electrical activity. It shows whether the heart rhythm is regular or irregular and provides the report. It also presents the information about the heart damage because of any heart diseases.
  3. Chest x-ray: This test is conducted to check the chest working functionality. It shows the picture of the heart and can be identified as any heart damages.
  4. Cardiac catheterization: This procedure is used to treat and diagnose the certain special conditions of the heart.
  5. Electrophysiology Study: This study is done with the help of cardiac catheterization tests. It is used to record certain electrical and heart signals and its response with some medication. It provides the doctors to know where exactly electrical signals are damaged in the heart.
  6. Blood Tests: This test is performed to check the blood levels with the amount of potassium, magnesium, calcium and other minerals and chemicals in the body. This chemical deficiency will lead to heart electrical signal problems.

Tips to protect from cardiac arrest and reduce its risk:

  • No smoking: Quit smoking We all know the dangerous diseases caused due to the smoking habit. It affects all internal body system and reduces the longevity.
  • Avoid Alcohol: Alcohol consumption leads to damage to healthy body immune system and other organs. Excess consumption of alcohol will affects the body. Not more than 2 drinks per day are recommended by the doctors.
  • Eat food: Always eat healthy food. Adopt organic fresh vegetables, fruits, leafy vegetables which lowers the risk of heart diseases.
  • Drink juices: Juices will remove toxins from the body and clears from all the wastes. Drink at least one fresh juice per day. Always prefer juices which are with no added sugars, no flavors and with no excess amount of water. Try to drink veggies and fruit juices.
  • Do exercise: Exercises will reduce not only heart risks but also keeps health, body and mind fresh and peaceful. Make sure to do regular exercise every day without fail. Yoga is also the best exercise for heart patients -but do under experts guidance only.
  • Reduce Obesity: Obesity is also considered as the main reason behind the cardiac arrest. Overweight is the result of unhealthy food. Maintain proper weight and keep diet balance in your life. Do not overeat.
  • Control Diabetes: Diabetes is the main cause of several heart diseases. The high glucose levels in the blood will decrease the proper blood flow in the heart and other organs of the body. It makes a person sick and decreases the longevity of the human. It ruins away a healthy life. Ones a person affected with diabetes cannot recover completely.

Adopt fruits which lowers the risk of heart diseases

  • Avoid sodium: Intake of more quantity of sodium is the root factor of giving birth to many sorts of heart and other diseases both for the internal and external system.
  • Control the sodium quantity in food and if possible avoid it totally. Skip adding salt in salads and other snacks. Never add extra salt additionally in your food and do not intake it directly.
  • Fruits: Start eating at least one type of fruit every day. Try to include different fruits in your daily meals. If you are undergoing any sort of medication or treatment eat according to the doctor's prescription.

Men or Women, who have a higher risk of cardiac arrest:

Women have lesser cardiac arrest risk when compared to men irrespective of age. According to the research 3:1 ratio of men: women in the total population are affected by cardiac arrest because of the excess amount of CHD present in the men.

Latest heart protection technologies:

Life Vest Wearable Defibrillator: According to Dr. VivekDhruva, Graber's cardiologist from the University of Maryland Upper Chesapeake Health, Wearable defibrillator protects the heart from heart attacks and cardiac arrest. It checks the heart rhythms time-to-time and gives shock treatment whenever necessary. If a person is affected with a heart attack or cardiac arrest, this LifeVest detects the change in heart rhythm and automatically it gives shock treatment to the person and controls the heart rhythm without any prior notification from anyone.

Hope such new technologies to prevent heart diseases and other cardiac arrests will come soon into the market and protects numerous people.
