Objective:

To know the epidemiological behavior and associations of AF in Mexican population.

Material and methods:

8,686 patients from 38 cardiologists participating in REMECAR were analyzed. They were divided by gender and age, the comorbidities studied were obesity, chronic kidney disease (CKD), high blood pressure (HBP), diabetes mellitus (DM), dyslipidemia, stroke, chronic obstructive pulmonary disease (COPD), hypothyroidism, heart failure (HF) and ischemic heart disease (IHD). Program used: IBM SPSS Statistic.

Results:

AF was diagnosed in 498 patients (5.7%), with higher prevalence in men (6.1% vs. 5.3%) and older age in women (74.3 ± 12.1 vs. 70.5 + -12.3 years, p<0.0001). In those under 60 years, AF was associated in women with HF, in men with CKD, DM, stroke, hypothyroidism and HF. In women older than 60 years, AF was associated with CKD, dyslipidemia, stroke, chronic COPD and HF, in men with CKD, stroke, COPD, hypothyroidism, HF and IHD. AF in women increase the probability 1.13 for obesity, 1.13 for HBP, 2.8 for CKD, 2.9 for COPD, 4.3 for stroke and 6.5 for HF, in men increase the probability 1.05 for HBP, 1.4 for DM, 2.1 for CKD, 2.4 for COPD, 3.0 for hypothyroidism, 4.7 for stroke and 6.0 for HF.

Conclusions:

AF is a very common arrhythmia, with a higher prevalence in patients attending the cardiology consultation, in men and with an older age of presentation in women. The older the age, the higher the prevalence of AF and comorbidities, HF is the most frequent condition associated with AF.
