RESUMEN
Type 2 diabetes mellitus (T2DM) is one of the most common chronic diseases worldwide and is highly prevalent in Mexico, as 10.2% of the adult population harbors this condition. T2DM is usually associated with cardiovascular comorbidities, including arrhythmias. Metabolic impairment is one of the mechanisms that contribute to tissue remodeling that affects atrial structure, and concomitant, the cardiac conduction system, both could result in atrial fibrillation (AF). AF is estimated to affect more than a half million Mexicans, and its incidence is expected to keep rising. According to national registries, T2DM is present in 28.4% of Mexican patients with AF and the coexistence of both diseases is associated with a higher risk of stroke. In clinical practice, the CHA2DS2-VASc risk score is useful for stroke risk stratification in patients with AF to facilitate the adequate use of anticoagulation therapy. T2DM is among the items of the CHA2DS2-VASc score because it correlates with an intrinsic prothrombotic state. In this narrative review, we present information that highlights the need for optimal glucose control and adequate anticoagulation in subjects with T2DM and AF.

RESUMEN
PURPOSE: We aimed to describe time-trends in the use of NOACs among a group of ambulatory patients with nonvalvular atrial fibrillation (NVAF) in Colombia and to describe treatment patterns and user characteristics. METHODS: Using the Audifarma S.A administrative healthcare database in Colombia, we identified 10 528 patients with NVAF aged at least 18 years between July 2009 and June 2017 with a first prescription (index date) for apixaban, dabigatran or rivaroxaban (index NOAC) and followed them for at least year (max, 8.0 years, mean 2.2 years). We described patient characteristics, NOAC use over time, and the dose of the first NOAC prescription. RESULTS: A total of 2153 (20.5%) patients started on apixaban, 3089 (29.3%) on dabigatran and 5286 (50.2%) on rivaroxaban. The incidence of new users of apixaban and rivaroxaban increased over study years while for dabigatran it decreased. Mean age at the index date was: 78.5 years (apixaban), 76.5 years (dabigatran), 76.0 years (rivaroxaban). The percentage of patients started NOAC therapy on the standard dose was: apixaban 38.0%, dabigatran 30.9%, rivaroxaban 56.9%. The percentage still prescribed their index NOAC at 6 months was apixaban 44.6%, dabigatran 51.4%, rivaroxaban 52.7%. Hypertension was the most common comorbidity (>80% in each NOAC cohort). CONCLUSION: During the last decade, the incidence of NOAC use in patients with NVAF affiliated with a private healthcare regime in Colombia has markedly increased. Future studies should evaluate whether the large number of patients with NVAF starting NOAC treatment on a reduced dose are done so appropriately.

Atrial fibrillation (AF) is a prominent risk factor for stroke and a leading cause of death and disability throughout Latin America. Contemporary evidence-based guidelines for the management of AF and stroke incorporate the use of practical and relatively simple scoring methods to estimate both stroke and bleeding risk, in order to assist in matching patients with appropriate interventions. This review examines consistencies and differences among guidelines for reducing stroke risk in patients with AF, assessing the role of user-friendly scoring methods to determine appropriate patients for anticoagulation and other treatment options. Current options include warfarin and direct oral anticoagulants such as dabigatran, rivaroxaban, apixaban, and edoxaban. These agents have been found to be superior or noninferior to standard vitamin K antagonist anticoagulation in large randomized trials. Potential benefits of these agents mainly include lower ischemic stroke rates, reduced intracranial bleeding, no need for regular monitoring, and fewer drug-drug and drug-food interactions. Expert opinions regarding clinical situations for which data are presently lacking, such as emergency bleeding and stroke in anticoagulated patients, are also provided. Enhanced attention and adherence to evidence-based guidelines are essential components for a strategy to reduce stroke morbidity and mortality across Latin America.
