Prevalencia de fibrilación auricular, factores relacionados y predicción de enfermedad cerebro vascular, Hospital Vicente Corral Moscoso, 2008-2009

Abstract:

Objective: To determine the atrial fibrillation prevalence, the associated factors and prediction of cerebrovascular disease in patients older than 44 years,admitted in the Internal Medicine Department of the Vicente Corral Moscoso Hospital, during 2008-2009.- Material and methods This study was a crosswise one, in a representative sample of 520 patients. This sample was calculated on the socket of a finite universe (970), confidence level of 95%, acuity of 2% and forfeitures of 20%.- Results: The median of the age was of 65.5 years, with a rank between 45 and 79. The women were represented with 56.2%. The atrial fibrillation prevalencewas 6.3% (CI 95% 4.22-8.38); 7.2% in female (CI 95% 4.24-10.16), and 5.3% in male (CI 95% 2.4-8.2). People between 45 and 65 years had a 10.4% of prevalence (CI 95% 6.87-13.83) and 1.3% in patients older than 64 years (CI95% 0-2.75). The 57.6% of the patients had moderate risk to develop cerebrovascular illness, and 42.4% had a high risk. The association betweenatrial fibrillation with hypertension, cardiac failure and the chronic obstructive pulmonary disease was significant (RP 5.5, CI 95% 2.8-10.7 and p=0.000; RP 6.4, CI 95% 3.4-12.0 and p=0.000 and RP 3.1, CI 95% 1.6-6.0 and p=0.001 respectively). But, with the diabetes mellitus type 2, the association was not significant (RP 0.5, CI 95% 0.1-1.5 and p=0.166). Conclusion.- The atrial fibrillation prevalence was of 6.3% (CI 95% 4.22-8.38) and it was associated positively with arterial hypertension, cardiac failure and chronic obstructive pulmonary disease
