Cardiac Arrest Treatment in Mumbai, India

Cardiac arrest takes place when the heart either stops beating or beats too rapidly to effectively pump blood. This leads to a sudden collapse and loss of responsiveness, with symptoms appearing without any warning. For this reason, it is also referred to as sudden cardiac arrest.

If not treated immediately, this life-threatening condition can be fatal.

During cardiac arrest (also known as cardiopulmonary arrest), the heart ceases to pump blood, putting the entire body and organs in jeopardy within minutes, as they require a constant supply of oxygen, which is delivered through the blood.

Emergency interventions, such as cardiopulmonary resuscitation (CPR) and defibrillation, are crucial. CPR helps maintain oxygen in the lungs and ensures it reaches the brain, while an electric shock can restore a normal heart rhythm. Both CPR and defibrillators can be life-saving.

Alternative Names

Cardiac arrest is known by various names, each highlighting different aspects of the condition. "Sudden cardiac arrest" emphasises the unexpected nature of the event, where the heart suddenly stops beating. "Sudden death syndrome" is used when the arrest leads to immediate death if not treated quickly, often in otherwise healthy individuals. "Cardiopulmonary arrest" refers to the failure of both the heart and lungs to function, while "cardiorespiratory arrest" underscores the failure of both the heart and respiratory systems. These terms all describe a life-threatening emergency requiring immediate treatment, such as CPR or defibrillation, to restore normal heart rhythm and prevent death.

Symptoms of Cardiac Arrest

Sudden cardiac arrest can be identifiable if an individual falls unconscious or is unable to respond and has low or no pulse and breathing. In most cases, the patient himself may not be able to observe or act upon the symptoms since it occurs abruptly. The following symptoms may occur just before the cardiac arrest.

• Heart palpitations
• Dizziness
• Lightheadedness
• Weakness
• Loss of consciousness (fainting)

Causes of Cardiac Arrest

Before cardiac arrest, abnormal, rapid electrical impulses disrupt the normal ones that regulate your heartbeat.

Most sudden cardiac arrests are caused by abnormal heart rhythms (arrhythmias), with the most common life-threatening arrhythmia being ventricular fibrillation (v-fib). This condition involves erratic, disorganised electrical impulses in the heart's ventricles (lower chambers), preventing the heart from pumping blood. Without a heartbeat, oxygen-rich blood cannot circulate throughout the body.

Various conditions and circumstances that lead to these abnormal heart rhythms are the primary causes of sudden cardiac arrest. These include:

• Cardiomyopathy
• Medications for other health issues
• Heart attack
• Heart failure
• Recreational drugs like cocaine
• Brugada syndrome
• Long QT syndrome (LQTS)

Other potential causes of cardiac arrest include:

• Coronary artery disease (CAD)
• Congenital heart conditions
• Changes to the heart’s structure due to disease or infection
• Intense physical exertion or blood loss
• Infectious diseases
• Respiratory issues
• Severe trauma
• Toxic substances (poisoning)

Many of these factors either reduce oxygen levels or decrease blood volume, interfering with the heart’s ability to function properly.

Types of Cardiac Arrest

There are several types of cardiac arrest, including:

• Cardiac arrest: The heart suddenly stops functioning, leading to a cessation of blood flow and circulation.
• Sudden cardiac arrest: A cardiac arrest that happens without warning.
• Sudden cardiac death: This occurs when a cardiac arrest leads to death within an hour of the onset of symptoms.
• Aborted sudden cardiac death: This happens when CPR and medical intervention successfully prevent death caused by cardiac arrest.

Diagnosis and Testing

Identifying the cause of a cardiac arrest is crucial for providing the correct treatment. During or shortly after resuscitation, healthcare providers may use the following tests to help diagnose or rule out the conditions that triggered the cardiac arrest:

• Electrocardiogram (ECG or EKG) to detect irregular heart rhythms and signs of a heart attack
• Blood tests, including chemistry tests for electrolytes and blood gas studies
• Chest imaging, such as X-ray and computed tomography angiography (CTA), to detect lung issues like pulmonary embolism or pneumothorax
• Echocardiogram (heart ultrasound) to check for cardiac tamponade (fluid around the heart) or structural heart disease.
• Additional heart tests like cardiac catheterisation to find blockages in coronary arteries or electrophysiology studies to investigate heart rhythm disorders

Cardiac Arrest Treatment

During cardiac arrest, the heart stops beating, preventing blood from reaching the brain and other vital organs. Every second is critical, so it's crucial to quickly recognise cardiac arrest and begin immediate cardiopulmonary resuscitation (CPR). CPR involves chest compressions to maintain blood flow, offering the best chance of survival. Without CPR, cardiac arrest is fatal.

Here are the key steps for performing hands-only CPR:

1. Call for help: Call an ambulance; if you're in a public area, ask for an AED (automatic external defibrillator).
2. Get in position: Make sure that the person is lying flat on their back, kneel beside them, and lock your elbows, keeping your arms straight before beginning compressions.
3. Press hard and fast: Perform chest compressions at a rate of 100 to 120 per minute, pressing down about 2 inches deep on the centre of the chest.
4. Continue CPR: Keep performing compressions until professional medical help arrives.

Cardiac Arrest Prevention

You may need certain tests like:

• Electrocardiogram (ECG or EKG)
• Heart MRI (magnetic resonance imaging)
• Blood tests to evaluate electrolytes involved in the heart's electrical function
• Ambulatory monitoring
• Echocardiogram (echo)
• Cardiac catheterisation
• Electrophysiology study

Preventive treatments to reduce the risk of another cardiac arrest episode include:

• Implantable cardioverter defibrillator (ICD)
• Treatments for arrhythmias in individuals at risk
• Medications such as beta-blockers
• Addressing heart artery blockages through coronary artery bypass surgery (CABG) or angioplasty

You can lower your risk of cardiac arrest by adopting a healthy lifestyle, including:

• Avoiding tobacco
• Eating heart-healthy foods
• Maintaining a healthy weight
• Being physically active most days of the week

Risk Factors for Cardiac Arrest

You may be at an increased risk of cardiac arrest if you:

• Have experienced sudden cardiac arrest previously or have a family history of it.
• Have a personal or family history of abnormal heart rhythms, such as long QT syndrome or ventricular tachycardia.
• Developed certain arrhythmias following a heart attack.
• Were born with heart or blood vessel issues.
• Have heart valve disease.
• Have a history of fainting.
• Suffer from heart failure due to conditions like dilated cardiomyopathy.
• Have hypertrophic cardiomyopathy.
• Experience significant fluctuations in potassium and magnesium levels in your blood.
• Are obese.
• Have diabetes.
• Use recreational drugs or medications that may increase the risk of life-threatening arrhythmias.

Complications of Cardiac Arrest

Survivors of cardiopulmonary arrest often face long-term challenges, including:

1. Cognitive difficulties: Many experience memory issues, difficulty concentrating, or trouble processing information, often due to lack of oxygen during the arrest.
   
   
2. Fatigue: Persistent tiredness, both physical and mental, is common, making everyday tasks exhausting, even with adequate rest.
   
   
3. Mental health challenges: Anxiety or depression can develop as a result of the traumatic experience, leading to emotional struggles and fear of future cardiac events.

These issues may require ongoing treatment and support, including therapy and lifestyle adjustments to improve quality of life.

When to Seek Emergency Medical Help?

• Call for help immediately: If someone collapses and loses consciousness, call an ambulance right away. Emergency medical services can guide you through performing CPR.
• Start CPR: Begin chest compressions to keep blood circulating until help arrives. Push hard and fast in the centre of the chest.
• Find an AED: Send someone to locate an Automated External Defibrillator (AED) if available. Use it as directed to shock the heart back into a normal rhythm.
• Act quickly: The sooner CPR and defibrillation are started, the better the chances of survival.
