What's the difference between an a-fib and a stroke?

Much: Symplistically, atrial fibrillation is an irregular heart rhythmn that can increase the risk for stroke. A stroke occurs when the blood supply to an area in the brain is cut off for a long enough period of time causing surrounding brain tissue death. ...Read more

Atrial Fibrillation (Definition)

Atrial fibrillation is an irregular and often rapid heart rate that commonly causes poor blood flow to the body. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms include heart palpitations, shortness ...Read more

A-fib, stroke prophylaxis: arixtra works diff from warfarin, no approval by fda & no studies establishing its effectiveness. How can it be acceptable?

A-fib, stroke prophylaxis: arixtra works diff from warfarin, no approval by fda & no studies establishing its effectiveness. How can it be acceptable?

Agree with you: Arixta is effective in for venous blood clots. It works faster than warfarin but has to be injected, so it is given temporarily. Sometimes it is selected bec of a Heparin allergy. For atrial fibrillation, there are 3 new pills (pradaxa, xarelto, eliquis) that can be used instead of warfarin. They are very attractive because they dont require monthly blood test monitoring. ...Read more

Likely: Beyond a shadow of a doubt is a term that is seldom used in medicine. As previously answered a stroke may come from multiple sources, including the heart. New numbness, speech difficulty, weakness associated with "a hamster running around in your chest" is suggestive of a heart source. ...Read more

What meds can I use to control my a fib? What are the risks and side effects of medications to control my atrial fibrillation or to reduce the risk of stroke? What are the risks/benefits of other treatment options?

The : The treatment of atrial fibrillation has two important components: 1) treating the rhythm, and 2) preventing stroke. There are two strategies for treating the rhythm. The first is called the rate control strategy, and involves using medicines to prevent the heart rate from going too fast. These medicines do not prevent atrial fibrillation episodes, but are generally effective at preventing fast rhythms and also tend to have few side effects. This is a good strategy for people who do not have severe symptoms from atrial fibrillation, such as older less active people. The second strategy is called the rhythm control strategy, and involves using medications that are designed to maintain normal sinus rhythm and prevent episodes of atrial fibrillation. This strategy may be more desirable for people who are vey symptomatic when in atrial fibrillation such as young, active people. Unfortunately, this strategy tends to be less successful because recurrence of atrial fibrillation is common. The rhythm control medications also tend to have more side effects than the rate control medicines, and in some cases the side effects can be severe. Neither strategy is better than the other at preventing stroke. For stroke prevention, warfarin (also called coumadin) is typically used for people at moderate or high risk. This medication has been shown to be superior in preventing stroke, but it also increases the risk of dangerous bleeding because it is a blood thinner. Patients at lower risk for stroke may just take an Aspirin tablet daily. This has a lower bleeding risk than warfarin. Lastly, some people are candidates for surgical or catheter-based ablation procedures. These procedures can cure atrial fibrillation, but are not always successful and not all people are good candidates. ...Read more

What is stroke?

What is stroke?

Damage to brain: A stroke is generally term referred to impairment or loss of function of part of the brain. This happens when blood supply to that part of the brain is interrupted due to a blockage resulting from plaque build up and/ or blood clot. Also rupture of blood vessel causing bleeding in the brain can result in stroke. ...Read more

What is stroke?

What is stroke?

Blood flow problem: Stroke is a problem with blood getting to brain tissue. It can be from blood vessels being clogged ("ischemic"), or from blood leaking out because of high blood pressure, blood disorders, trauma, etc. Either way, the tissue does not get enough oxygen and it gets injured. Eventually it will die if blood flow is not restored fast enough. ...Read more

What are "mini strokes"?

Mini stroke = TIA: A mini stroke, or TIA, is a stroke - a stroke with symptoms lasting less than 24 hours. This could be weakness of an arm or leg, numbness of the face, arm and leg, double vision, etc. A mini stroke or TIA cannot be determined by testing, it is a clinical diagnosis. The cause of a TIA is the same as for a regular stroke. Blood pressure and smoking are important risk factors. ...Read more

Can weed causes strokes?

Can weed causes strokes?

Minimal data: There's a report of binge smoking in adolescents who were irregular users of mj, having cerebellar strokes because of the binge. 2 died. There is a report that smoking mj is protective like aspirin. But mj causes vasoconstriction & fluctuations in arterial spasming that may contribute to a stroke in a susceptible person. No good data either way. Best not to smoke anything and mitigate your risks. ...Read more

Stroke (Definition)

Stroke is a loss of neurological function due to loss of blood flow to a part of the brain. This can be the result of clotting locally, an embolus from elsewhere in the vascular system or bleeding in the brain. It is usually manifest by a sudden ...Read more
