Study Finds Good Reason to Test CRP Levels in People with Afib

admin - January 4, 2012

atrial fibrillation, afib, afA HealthDay News article, published December 29, 2011 on, reports a clear association with higher levels of high-sensitivity C-reactive protein (hs-CRP) and increased mortality in patients with atrial fibrillation, independent of other risk factors. This is according to a study, called “Atherosclerosis Risk In Communities,” published in the January 1, 2012 edition of the Journal of Cardiology.

In the “Atherosclerosis Risk In Communities” study, José Hermida, M.D., Ph.D., of the University of Navarra in Pamploma, Spain, and colleagues analyzed the hs-CRP levels data from 293 patients with atrial fibrillation

Participants of the study were recruited from four communities throughout the United States. The baseline examinations of the participants were conducted from 1987 to 1989. Three additional exams were conducted every three years. Levels of hs-CRP were measured in blood samples obtained at the fourth visit and categorized in the following groups:

  • Levels less than 2  mg/L
  • Levels from 2.00 to 5.99  mg/L
  • Levels greater than 6 mg/L

After a median follow up of 9.4 years, 46% of the participants had died.

After adjustments were made based on age, gender, history of cardiovascular diseases, and cardiovascular risk factors, the hazard ratio (or associated risk) for the mortality rate of participants was an hs-CRP of 2.52 or higher.

It was determined, therefore, that higher levels of hs-CRP is an indicator for the risk of death in patients with atrial fibrillation.

This study shows another reason to stay on top of your health with regular screenings. Make an appointment with a trusted health source like Life Line Screening or your doctor today to get an atrial fibrillation screening and/or have your CRP levels tested.

Stay healthy!
