Mortality in a cohort of primary care patients treated with vitamin K antagonist anticoagulants.
The use of anticoagulants to prevent embolic events in Spain is very high, tending to a progressive increase. For this reason, we intend to analyse the mortality of patients from a metropolitan area of Granada treated with vitamin K antagonist anticoagulants (VKA), over 2 non-consecutive years. ⋯ At 2 years of follow-up, 1 in 5 patients treated with VKA died. The presence of chronic kidney disease, chronic obstructive pulmonary disease and a longer treatment time were independently associated with this increase of mortality. Most of the patients were anticoagulated by atrial fibrillation, they were elderly and had a high prevalence of comorbidities.
