Editorial

Out-of-hospital Cardiac Arrest (OHCA) has gotten a lot of attention in recent years because the results have improved dramatically. Although there have been little improvements in neurologically intact outcomes, numerous localities have seen improved survival rates after modifying their cardiac arrest therapy. The pre-hospital management is crucial in determining whether a cardiac arrest patient can be revived and returned to a state of spontaneous circulation. However, the entire resuscitation chain, including inhospital care, has improved. Sudden Cardiac Arrest (SCA) and Rapid Cardiac Death (RCD) are both terms for the sudden cessation of cardiac activity with hemodynamic compromise, which can be caused by prolonged ventricular tachycardia (VT/VF), asystole, or Pulseless Electric Activity (PEA). Sudden circulatory collapse can also have non-cardiac causes. Acute or chronic coronary artery disease is the most prevalent cause of cardiac arrest, however other cardiac and non-cardiac disorders are also well-known causes. Every year, between 0.5 to 1 mortality per one thousand people is caused by sudden cardiac arrest outside of the hospital.

For decades, the survival rate has been extremely poor, with about 8-10% of patients surviving until hospital discharge, and survival in many rural locations is far lower. The significant death rate linked with SCA emphasizes the importance of identifying at-risk patients early. Risk variables, on the other hand, are poorly understood. Because coronary artery disease is the leading cause of SCA, cardiovascular risk factors, such as diabetes and smoking, increase the risk of OHCA. Obesity, on the other hand, has a lower risk of OHCA. In up to half of patients who die from cardiovascular causes, cardiac arrest may be the first sign of heart illness. The cause of IHCA varies depending on the patient's kind and location, however in many hospitals, the development of respiratory distress to cardiac arrest is the most common. Despite of new medications, survival following cardiac arrest has grown steadily over the last 15 years because of many advances in care systems. The electrical vulnerability to ventricular arrhythmia has yet to be tested. This is primarily owing to the myocardium's electrical activity being dynamic. Although invasive electrophysiological testing has been advised for determining the inducibility of ventricular arrhythmia, the usefulness of this approach is debatable.

These tests look at diverse elements of cardiac electrophysiology as seen on the surface Electrocardiogram (ECG), such as autonomic function changes due to increased circulating catecholamines, myocardial conduction delays, repolarization prolongation, and stretch-induced after-depolarizations. Over a 10- to 20-year period, the risk of SCD among athletes is predicted more. Athletes, particularly those involved in competitions, are at an increased risk of SCA due to their increased physical activity, especially if they have hypertrophic cardiomyopathy, abnormal origin of coronary arteries, myocarditis, Arrhythmic Right Ventricular Cardiomyopathy (ARVC), mitral valve prolapse, aortic stenosis, or coronary arteriosclerosis. In 2005, the European Society of Cardiology (ESC) established guidelines for young competitive athletes' pre-participation screening:

i) Personal and family history, as well as a physical examination

ii) ECG with 12 leads

iii) Any aberrant findings should be investigated further (e.g., echocardiography or cardiac magnetic resonance imaging (CMR)

iv) Re-evaluation should be done after two years.

A family screening of patients with unexplained OHCA should be considered as well. In this case, an ECG and stress testing, echocardiogram, or magnetic resonance imaging (MRI), as well as genetic testing, may be relevant.

Continuous chest compressions ("hands-only Cardiopulmonary Resuscitation (CPR) without ventilation") may not have a deleterious effect on neurologic prognosis, at least in the first few minutes following SCA, according to growing research. People who are afraid of infection may benefit from nose-to-mouth or mouthto-mouth breathing, which is suggested during CPR. Additionally, the use of automated external defibrillators (AEDs) is strongly advised. Multiple recent advancements in the care of patients with Out of Hospital Cardiac Arrest may have a synergistic effect. The establishment of cardiac arrest centers, post-OHCA treatment guidelines, therapeutic hypothermia advancements, and primary percutaneous intervention (PPCI) in post-OHCA are all expected to enhance outcomes further in the future
