Facts and myths about atrial fibrillation

Heart, Medical, Health, Disease

"In a meta-investigation including over a large portion of a million people, there was no proof of mischief to exertion. The hazard is the most reduced for the individuals who move, however not overstated, for example spend under 2000 thousand on physical movement. hours a year. Dormant individuals, this hazard increments, just as in over-preparing individuals "- clarifies prof. dr hab. n. drug. Maria Trusz-Gluza, for a long time the leader of the first Department and Cardiology Clinic of the Silesian Medical University in the Upper Silesian Cardiology Center in Katowice Ochojiec. Most investigations show that standard and moderate exercise positively affects physical execution, heart cadence and personal satisfaction of patients with atrial fibrillation.

It is valid, notwithstanding, that particularly in men rehearsing perseverance disciplines, for example those related with extreme and delayed exertion, the danger of atrial fibrillation corresponding to everyone might be more prominent.

  • Just high liquor utilization builds the danger of atrial fibrillation.

The expression "high utilization" is generally comprehended to mean the measure of in excess of 2 mixed drinks for every day. Notwithstanding, numerous investigations have demonstrated that even with "low liquor utilization" - a couple of beverages daily - the hazard increments by up to 17%. Researchers from the University of Tsukuba in Japan determined that the general danger of atrial fibrillation is 51 percent. higher in liquor consumers regularly contrasted with teetotalers and infrequent consumers. With each 10 grams of liquor devoured every day, the hazard expanded by 8 percent.

In cardiological practice, it isn't phenomenal to discover youngsters who have had their first AF after liquor misuse.

  • Caffeine is a hazard factor for atrial fibrillation.

Customary drinking of espresso with some restraint doesn't cause atrial fibrillation - this is the end come to by Swedish researchers from the investigation, the aftereffects of which were distributed in 2015 in the diary BioMed Central.

The investigation secured a huge gathering of 42,000 men and 35 thousand ladies. In 1997, they finished definite surveys in regards to wellbeing, diet and way of life. They were likewise asked how frequently they drink espresso. Following 12 years, the specialists investigated the information on the respondents gathered in emergency clinic registers. On this premise, they surveyed that supporters of the day by day alcoholic minimal dark don't experience the ill effects of AF.

"Furthermore, in an enormous meta-examination including more than 200,000 subjects, it worked out that a low portion of caffeine lessens atrial fibrillation scenes by 11 percent, and a bigger portion significantly more. The finish of the investigation was: caffeine admission not exclusively doesn't build the danger of atrial fibrillation, yet decreases it by 6%. for each 300 mg of energizer "- says prof. Trusz-Gluza.

  • Paroxysmal and tenacious atrial fibrillation are related with a comparable danger of thromboembolic occasions.

The ACTIVE investigation, just as a huge Swedish vault, indicated that the hazard is practically indistinguishable. Along these lines, the 2010 European rules on atrial fibrillation expressed that the hazard in patients with paroxysmal fibrillation doesn't vary from that of constant and diligent. "In any case, a couple of months back an exceptionally huge meta-investigation was distributed dependent on huge investigations of NOAC tranquilizes just as nutrient K rivals. It shows that in patients with non-paroxysmal atrial fibrillation, the danger of ischemic stroke or fringe embolism is 38% higher. than in patients with paroxysmal arrhythmia, all out mortality likewise increments (by 22%) "- notes prof. Trusz-Gluza.

  • Anticoagulation 100% ensures patients with atrial fibrillation against ischemic stroke.

As per current rules for the counteraction of stroke, patients who are at high danger of thromboembolic confusions ought to get oral anticoagulants (without contraindications). Research has indicated that warfarin diminishes this hazard by 64%, and NOAC drugs have considerably more prominent viability, yet it is as yet not 100%.

  • Atrial fibrillation enduring under 48 hours. (not at all like more than 48 hours) doesn't require anticoagulation or transesophageal echocardiography before cardioversion.

"In 1986, the principal US rules on atrial fibrillation were distributed, whose creators reasoned that there was an insignificant danger of thrombus arrangement in such a brief timeframe. Be that as it may, effectively an examination utilizing transesophageal echocardiography in patients with atrial fibrillation as long as 72 hours, distributed in 1995, demonstrated that the nearness of thrombus was normal and was 14 percent. " - remarks prof. Trusz-Gluza.

Thus, the FinCV Finnish cardioversion register indicated that this 48-hour time window isn't totally secure. The danger of thrombus development may increment following 12 hours and influence old patients, ladies, patients with cardiovascular breakdown, diabetes mellitus and mitral stenosis.

Accordingly, current European 2016 rules accommodate the beginning of anticoagulation with either heparin or a NOAC tranquilize at the earliest opportunity before every cardioversion of atrial fibrillation or shudder.

  • A patient treated with a nutrient K rival ought to follow an eating regimen with a constrained nutrient K content.

Individuals who are endorsed oral anticoagulants from the gathering of nutrient K adversaries as a rule get dietary proposals comprising in constraining nourishments plentiful in nutrient K.

"Two Italian papers demonstrate that the Mediterranean eating regimen doesn't influence the dependability of anticoagulation and can be prescribed to patients treated with VKA. Vacillations can just happen with an extremely enormous stockpile of nutrient K "- says prof. Trusz-Gluza.

It merits including that in a report distributed after the PREDIMED concentrate on the danger of creating atrial fibrillation, eating a Mediterranean eating regimen without improving it with nuts decreased the danger of creating atrial fibrillation by 38%, and in individuals more than 70 by 52%. The defensive impact was unmistakable following 2 years of utilizing this kind of diet.

  • Anticoagulation ought to be suspended before ophthalmic, dental or endoscopic methodology.

Systems with an okay of draining that don't legitimize intruding on anticoagulation incorporate different dental strategies (for example expulsion of 1-3 teeth), ophthalmic techniques (for example waterfall medical procedure), or endoscopic strategies without mediation. In the event that the patient is treated with a NOAC sedate, it is sufficient to keep a satisfactory interim between the organization of the medication and the system. The methodology ought to be performed not following taking the medication, however not long before taking the following portion.

  • Patients after gastrointestinal seeping without a stroke ought not continue anticoagulation.

"I allude to an ongoing Danish investigation including an enormous populace of patients with gastrointestinal seeping during anticoagulation. In the wake of draining halted, around 1/3 of patients didn't reestablish anticoagulation. It worked out that in patients who proceeded with anticoagulation, the danger of death or stroke was lower, however the danger of draining was higher, "clarifies prof. Trusz-Gluza.

  1. Does flu increment the danger of atrial fibrillation?

Flu is fundamentally connected with an expanded danger of atrial fibrillation, which can be decreased by inoculation, as indicated by an examination distributed in 'Heart Rhythm', introduced by prof. Trusz-Gluza.

In 2000-2010, researchers from Taiwan chose a gathering of more than 11,000 based on understanding databases in their nation. patients with recently analyzed atrial fibrillation. Four distinct individuals coordinated every one of them without flashing, which gave a sum of very nearly 57,000 examination members. The individuals who didn't have this season's cold virus and were not inoculated established the benchmark group. Examination of the information demonstrated that patients determined to have flu who were not inoculated had 18 percent. more serious danger of atrial fibrillation than controls. The individuals who were inoculated and had influenza had a comparable danger of arrhythmia as those in the benchmark group. Immunized individuals who didn't get influenza had minimal danger of glimmering. In this way, inoculation against flu can diminish the danger of atrial fibrillation.
