Here, the readers may find broad information regarding healthy eating and some tips on what to look for and what to avoid from grocery stores to restaurant dining.Additionally, marine-derived omega-3 polyunsaturated fatty acids (PUFAs) have been promoted for the prevention of sudden cardiac death due to their postulated ability to lower triglyceride levels, prevent arrhythmias, decrease platelet aggregation, and lower blood pressure. However, according to a systematic review published in 2012, omega-3 PUFA supplementation are not being associated with a lower risk of sudden cardiac death. Code teams
In medical parlance, cardiac arrest is referred to as a "code" or a "crash". This typically refers to "code blue" on the hospital emergency codes. A dramatic drop in vital sign measurements is referred to as "coding" or "crashing", though coding is usually used when it results in cardiac arrest, while crashing might not. Treatment for cardiac arrest is sometimes referred to as "calling a code". People in general wards often deteriorate for several hours or even days before a cardiac arrest occurs. This has been attributed to a lack of knowledge and skill amongst ward-based staff, in particular, a failure to carry out measurement of the respiratory rate, which is often the major predictor of a deterioration and can often change up to 48 hours prior to a cardiac arrest. In response to this, many hospitals now have increased training for ward-based staff.
The injury to tissue following ischemia can lead to structural and functional changes preventing the heart from continuing normal conduction cycles and altering heart rate. : 829 : 829

Non-atherosclerotic coronary artery abnormalities
Abnormalities of the coronary arteries not related to atherosclerosis include congenital coronary artery anomalies (most commonly anomalous origin of left coronary artery from the pulmonary artery), inflammation known as coronary arteritis, embolism, vasospasm, and mechanical abnormalities related to connective tissue diseases or trauma. These conditions account for 10-15% of cardiac arrest and sudden cardiac death. : 829 
Coronary arteritis commonly results from a pediatric febrile inflammatory condition known as Kawasaki disease. Other vasculitides can also contribute to increased risk of sudden cardiac death. Embolism, or clotting, of the coronary arteries most commonly occurs from septic emboli secondary to endocarditis with involvement of the aortic valve, tricuspid valve, or prosthetic valves. Coronary vasospasm may result in cardiac arrhythmias, altering the electrical conduction of the heart with a risk of complete cardiac arrest from severe or prolonged rhythm changes. Mechanical abnormalities with associated risk of cardiac arrest may arise from coronary artery dissection which can be attributed to Marfan Syndrome or trauma. : 829

Structural heart disease
Structural heart diseases not related to coronary artery disease account for 10% of all sudden cardiac deaths. Examples of these include:  cardiomyopathies (hypertrophic, dilated, or arrythmogenic), cardiac rhythm disturbances, myocarditis, hypertensive heart disease, and congestive heart failure. Left ventricular hypertrophy is thought to be a leading cause of sudden cardiac deaths in the adult population.
