What is Cardiac Arrest?

Cardiac arrest happens when the heart suddenly stops pumping blood. It causes an abnormal pulse rate, disabling the heart from pumping blood to the body. This drops the blood flow to the brain and other body organs. Cardiac arrest is a life-threatening condition, which requires immediate medical attention. 

What are the symptoms of Cardiac Arrest?

In some cases, patients may not experience any symptoms. However, the most common symptoms of cardiac arrest are listed below:

• Severe chest pain

• Sudden collapse 

• Zero pulse rate 

• No breathing 

• Unconsciousness

• Heart palpitations

• Weakness

What are the causes of Cardiac Arrest?

The causes of cardiac arrest include: 

• Arrhythmia - disruption of the cardiac signals, resulting in an abnormal heartbeat and blood flow

• Cardiomyopathy - thickening of heart muscles which contracts heart muscles

• Coronary Artery Disease - narrowing and thickening of coronary arteries, restricting cardiac blood flow 

What is the diagnosis of Cardiac Arrest?

The diagnosis of cardiac arrest involves a combination of clinical testing and diagnostic techniques, including:

• Medical History & Physical Examination: The medical practitioner begins with reviewing the patient's medical history which includes - previous health conditions, family history of heart disease, or other patient's medication. 

• ECG: An ECG or Electrocardiogram helps record the heart's electrical signals. Thus, it can determine an abnormal heartbeat caused by cardiac arrest.

• Blood Tests: Blood sampling is conducted to test the levels of cardiac enzymes - including troponin, creatine kinase, & brain natriuretic peptide. Abnormal levels of these enzymes help evaluate the damage to the heart muscles.

• Imaging Tests: Echocardiography - which is the ultrasound of the patient's heart helps the doctor evaluate the structure and function of the patient's heart. 

• Cardiac Catheterization: This diagnostic technique helps healthcare providers evaluate blood flow by visualizing the cardiac coronary arteries. Catheter - a thin tube is taken to the patient's heart through blood vessels. 

• Other Tests: Healthcare providers also perform some other diagnostic tests, depending upon the previous testing results. These include -  stress tests, cardiac MRI, or electrophysiology.

What is the treatment for Cardiac Arrest?

The cardiologist specialist treats cardiac arrest patients using the following treatment techniques and methods:

• Cardiopulmonary Resuscitation (CPR) - compressing the chest to regulate oxygenated blood throughout the patient's body.

• Automated External Defibrillators (AEDs) - analyzing cardiac rhythm and delivering shocks, if required. 

• Certain medications - including epinephrine help the heart start functioning properly. 

• Advanced airway management - comprising endotracheal intubation or supraglottic airway devices to regulate breathing

Surgical interventions - such as coronary angioplasty or stenting for blocked arteries.

What are the preventive measures for Cardiac Arrest?

Cardiac arrest can't be completely prevented. However, measures can help the risk of developing heart problems - including:

• Exercising, a nutritious diet, and a healthy lifestyle

• Effectively treating underlying health conditions

• Scheduled medical health check-ups

• Avoiding overdosage of any medication

What are the risk factors for Cardiac Arrest?

The following risk factors can lead to cardiac arrest in person:

• Coronary artery disease (CAD)

• Poor cardiac health

• Family history of cardiac issues

• Aging - especially above 50 

• Unhealthy habits including - smoking and poor dietary patterns

• Health issues - especially obesity, hypertension, or diabetes
