Sudden Cardiac Death (SCD) is responsible for a lot of deaths within the U.S. and other countries around the world. It’s not the same as a heart attack. A heart attack commonly occurs when advanced atherosclerosis (clogging from the arteries) gradually starves the heart causing irreversible damage. The heart lastly cannot work properly and stops. Unexpected cardiac death occurs when the electrical impulses that manage heart function turn out to be irregular resulting in an irregular heartbeat (arrhythmia). When the arrhythmia is intense enough the heart suddenly stops, depriving the brain of needed blood. Death often follows quickly unless emergency care is given immediately. Often sudden cardiac death happens when no other heart disease is discovered.

It has long been understood that eating fish can decrease the likelihood of heart attack along with other cardiovascular diseases. The reason? Fish, especially cold-water fatty fish, is high in two omega-3 polyunsaturated fatty acids (PUFA). These two fatty acids are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Omega-3 has been shown to decrease the build-up of artery blocking atherosclerosis and keep blood platelets from sticking collectively thus lowering the risk of heart attack and stroke.

But more recent research indicate that omega-3 fatty acids also have an effect on the dangerous arrhythmias that can cause sudden cardiac death by managing the impulses that manage heart rhythm. One study involved the utilization of mycocytes (cells that beat independently). By incorporating the totally free fatty acids to these cells arrhythmias were aborted. When the fatty acids had been taken out from the mycocytes the arrhythmias would reoccur therefore revealing that omega-3 fatty acids have a stabilizing effect on heart rhythm. The clear system for managing rhythm involved cell ion channels, proteins that manage the movement of sodium, calcium and potassium ions through the membrane of the cell.

Another study, executed by Danish researchers, examined the connection between heart rate variability and omega-3 fatty acids in healthy subjects. It had already been determined that heart arrhythmias could be absolutely impacted in patients who had been recent heart attack victims. These researchers wanted to determine if people otherwise free of heart disease could gain the exact same arrhythmia managing benefits from omega-3 fatty acids.

Sixty healthy adults had been randomly divided into three groups. The first group got day-to-day supplements containing 6.6 g of omega-3 (containing 3.0g EPA and 2.9g DHA). Group two received 2.0g of omega-3 (containing 0.9g EPA and 0.8g DHA). The other group received only an olive oil placebo. The supplements had been given for 12 weeks. Before and after the supplements had been consumed heart rate variability and blood cell fatty acids had been measured. It was found that center rate variability was favorably influenced by the amount of omega-3 consumed. In other words, the more omega-3 one consumed the higher the heart rate variability, especially in men with low heart rate variability prior to supplementing.

The researchers concluded that omega-3 fatty acids positively affected heart rate variability therefore having a protective effect on heart function. These finding were similar to those of earlier studies showing that omega-3 positively affects heart rhythm in patients who had suffered a previous heart attack. Since sudden cardiac death is the result of erratic heart rhythm, omega-3′s heart protective qualities show great promise within the fight against sudden cardiac arrest. The mechanical studies completed by these and other researchers seemed to confirm other studies that the oral ingestion of fish and fish oils supply prophylaxis for the prevention of fatal cardiac arrhythmias when taken regularly in little amounts. In simple terms, consuming fish and fish oil supplements can save lives.
