Late-breaking data presented at the European Society of Cardiology Congress 2017 in Barcelona, Spain have shown that ibuprofen is associated with greater increase in blood pressure (BP) than celecoxib or naproxen in patients with arthritis, potentially increasing their risk of cardiovascular (CV) events.

Total radiation higher in obese patients undergoing radiofrequency ablation

24 Sep 2019
Under new NHS criteria, obese patients “will not get non-urgent surgery until they reduce their weight”.

Obese patients are exposed to greater doses of radiation during radiofrequency ablation for atrial fibrillation, a recent study has found.

The study included 144 patients (median age, 60 years; 21 percent female) who received radiofrequency ablation for atrial fibrillation. Most (n=68) of the participants were overweight, while 48 were obese and 34 were normal-weight. The primary endpoint was the cumulative end dose (ED), defined as the sum of doses received during the preprocedural computed tomography and during the ablation procedure.

Both overweight (p=0.2) and obese (p=0.007) patients received higher EDs, with a 23- and 75-percent difference relative to their normal-weight counterparts, respectively. Only the effect on obese patients was statistically significant.

“Impact of obesity on overall exposure to ionizing radiation, which was previously considered to be major with a dose increase of >300 percent for obese patients, seems finally revealed to be moderate,” said researchers.

Multivariate, generalized linear regression analysis found that body mass index was a significant predictor of overall ED received (β per additional kg/m2, 0.27±0.11; p=0.009), as was X-ray time (β per additional minute, 0.27±0.10; p=0.004). Other univariate predictors such as sex, left atrial volume and the type of atrial fibrillation lost their significance after adjusting for covariates.

In addition, BMI was also a significant determinant of the success of the procedure (p=0.04), as were left atrial volume (p<0.001) and the type of atrial fibrillation.
