It is debated if omega-3 polyunsaturated fatty acids (N3PUFa) may be effective in preventing AF (atrial fibrillation), meta-analysis here.

However, much less has been considered this: Do N3-PUFAs prevent acute symptoms of periodic Atrial fibrillation?

The meta-analysis concentrate only in the long-term effects of prevention. My proposal focuses on the short-term i.e. the fact that the user can recognise AF first and then uses N3-PUFAs.

Please, assume that there is a validation method by which the user can easily detect that he has AF - he does this if he suspect it, i.e. feels special discomfort and special wave-like-pain the chest.

He takes each time in this case 20 ml of Müller omega-3 oil which has also vitamin D. The effect of recovering is immediate in prophylaxis. Assume the user has less than < 20 ng/ml vitamin D in blood each case, most of the time, 9 ng/ml so avitaminosis.

My conjecture is that N3-PUFAs can prevent the acute symptoms of periodic AF.

How can N3-PUFAs prevent the acute symptoms of periodic AF? What is the role of vitamin D here?

  • $\begingroup$ Does it matter what the cause is of said atrial fibrillation? IHSS, CHF, valvular disease, DM, HTN, MI, other? $\endgroup$ – anongoodnurse Nov 8 '14 at 2:38
  • $\begingroup$ @anongoodnurse Thank you for your good comment! It does not matter what is the cause. I will specify this when I understand what could be most practical to study and detect. $\endgroup$ – Léo Léopold Hertz 준영 Nov 8 '14 at 6:36

Omega 3 Fatty Acids cannot prevent the the acute symptoms of periodic A Fib, nor is there a role for vitamin D in the treatment of acute symptoms of periodic AF.

Atrial Fibrillation with the symptom of chest pain is very worrisome and requires urgent or emergent treatment. The most common treatments are heart rate control via IV antiarrhythmics, or cardioversion, either electrical or chemical, usually done in the emergency room.

There has never been a study wherein AFib accompanied by symptoms of chest pain was treated by Omega 3 Polyunsaturated Fatty Acids and there never will be, because N3PUFA does not cardiovert arrhythmias nor does it effect heart rate in AFib.

No medical body of any kind would support such a study.

Finally, there is no convincing evidence that N3PUFAs decrease the incidence of AFib, and this has been studied often, because eating 4-5 servings of fish per week has been shown to have a beneficial effect on A Fib. That gives reason to hope that N3PUFA supplements might be similarly beneficial. However:

The role of omega-3 polyunsaturated fatty acids in the setting of AF is controversial. Although some studies demonstrate a lower incidence of AF recurrence with omega-3 polyunsaturated fatty acids use, others have shown an increased risk. Further studies are needed to assess the role of N3-PUFAs in the prevention of AF.[1]

If N3PUFAs have not been proven to help AFib long term, there is no hope whatsoever that studies will be undertaken to shown their effect in the acute treatment of symptomatic AFib, which is the scenario you have described.

Atrial Fibrillation becomes symptomatic when the arrhythmia results in decreased perfusion of various organs. If there is decreased perfusion to the heart, the presenting symptoms may be of ischemia (usually chest pain or pressure) or shortness of breath due to decreased cardiac output and decreased oxygenation in the lungs. If it is severe enough, fainting may occur from decreased blood pressure, and decreased perfusion of the brain. If it is not severe, it may result in a sensation of flip-flopping in the chest, or palpitations (irregular, thumping, or pounding heartbeats). There are other symptoms of A Fib but since you mentioned chest pain, I won't elaborate.

  • $\begingroup$ Actually, I read somewhere that high doses in the case when the patient feels flip or flop in the chest can actually worsen atrial fibrillation. So the admission of this in high amount should be avoided in such cases. No positive effect shown. The elevation of the sleeping position is the way to go until the patient feels go unless no other approach made for the particular patient. $\endgroup$ – Léo Léopold Hertz 준영 Dec 6 '14 at 20:41
