Anticoagulation in atrial fibrillation: NOAC prescribing in primary health care.

Background Few studies assess the use of non-vitamin K antagonist oral anticoagulants (NOACs) in daily practice for the prevention of thromboembolic complications associated to nonvalvular atrial fibrillation (AF). Objectives Describe NOACs' use and analyze its prescribing pattern. Evaluate possible factors associated to adverse events (AEs) and the applicability of prescription support forms. Methods We included patients with AF treated with a NOAC during 2014 in three primary healthcare centers in Barcelona, Spain. Demographic and clinical data was collected, as well as embolic and bleeding risk and reported AEs. Results A total of 101 patients were included, with a median age of 75 years. The NOACs most frequently prescribed were dabigatran and rivaroxaban. An 87.2% of the patients were receiving the recommended dosage. A potential bleeding risk was present in 47% of the subjects. Ten AEs were reported, of which eight hemorrhages. Patients who presented an AE were >65 years and had a higher proportion of concomitant treatment and/or co-morbidities that could prompt to bleeding (p < 0.001). Conclusions Current treatment practice is according to regulatory agencies' recommendations. Close monitoring is especially needed in patients >65 years and at higher risk of bleeding. Prescription support forms help good prescribing and identifying potential individuals at high risk of AEs.

Tirofiban and eptifibatide treatment of patients presenting with acute coronary syndrome with non-ST segment elevation.

OBJECTIVE: This retrospective study was conducted to determine the usage patterns and tolerability of tirofiban and eptifibatide during the first year of their use. METHODS: We have assessed the appropriate use of these drugs according to the criteria implemented by the Clinical Institute of Cardiovascular Disease as part of a protocol for treating acute coronary syndrome with non-ST segment elevation. RESULTS: 37 patients received tirofiban and 19 patients received eptifibatide. These patients were at high risk of poor outcomes such as myocardial infarction or death. Tirofiban and eptifibatide were used according to the indication criteria: only one case fell outside them. Dosing, time for drug initiation (from last chest pain) and time of infusion were considered appropriate. Tirofiban was involved in two cases of minor bleeding complications and eptifibatide in one case of thrombocytopenia (80,000 platelets per millimeter). These mild adverse drug reactions were reversible with the early withdrawal of the drugs. CONCLUSIONS: This study shows that tirofiban and eptifibatide have been used optimally, with a close adherence to the pre-established protocol. Both drugs have shown a good level of tolerability.
