Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Comparação entre a lidocaína e a acupuntura no tratamento da taquicardia ventricular induzida com dopamina em equinos anestesiados com halotano Comparative study between lidocaine and acupunture in the treatment of ventricular tachycardia induced by dopamine in horses anesthetized with halothane

Os efeitos da lidocaina e da acupuntura nos pontos bilaterais associados ao pericárdio 6 (Pc6-Neiguan) e ao coração 7 (C7-Shenmen), no tratamento da taquicardia ventricular (TV) induzida por dopamina em equinos anestesiados com halotano, foram avaliados e comparados. Seis equinos, distribuídos em três grupos: grupo-controle (GC), grupo tratado com acupuntura (GA) e grupo tratado com lidocaína (GL), foram anestesiados três vezes cada, com intervalo de uma semana entre cada anestesia. Avaliaram-se os parâmetros cardiovasculares (frequência cardíaca, pressão arterial e eletrocardiografia), os respiratórios (frequência respiratória, capnografía, saturação de hemoglobina e hemogasometria) e o escore de recuperação. A dose arritmogênica da dopamina (DAD) foi determinada a partir da infusão de 70µg/kg/min IV durante 10 minutos, sem interrupção, preenchendo o critério arritmogênico: quatro ou mais complexos ventriculares prematuros seguidos, com duração de pelo menos 15 segundos ou TV sustentada. O tempo médio de aparecimento da DAD ou da TV foi de 6,05±0,45 minutos nos animais não tratados, e a TV se reverteu espontaneamente aos 2,7±0,2 minutos. O grupo tratado com acupuntura reverteu a TV no tempo médio de 1,8±0,2 (P<0,05) em relação ao grupo tratado com lidocaina 1,3±0,2 (P<0,01). Os tratamentos mostraram-se eficientes na reversão TV.<br>The effects of lidocaine and acupuncture in the associated bilateral points, i.e. pericardium 6 (Pc 6- Neiguan) and heart 7 (H7 - Shenmen), on the ventricular tachycardia (VT) induced by dopamine were evaluated in horses anesthetized with halothane. Six horses were distributed in three groups: control group (CG), acupuncture treated group (AG), and lidocaine treated group (LG). They were anesthetized three times each one using halothane with one week interval between each anesthesic procedure. Cardiovascular (heart rate, arterial pressure, and ECG) and respiratory (respiratory rate, capnometry, hemoglobin saturation, and blood gas analysis) parameters and recovery score were evaluated. The arrhythmogenic dose of dopamine (ADD) was determined by the infusion of 70mg/kg/min during 10 minutes without interruption fulfilling the arrhythmogenic criterion by the presence of four or more ectopic ventricular contractions during at least 15 seconds or maintained VT. The mean time for the occurrence of ADD or VT was 6.05 ± 0.45 minutes in no treated animals and the VT reverted spontaneously in 2.7 ± 0.2 minutes. The group treated with acupuncture reverted the VT in a mean time of 1.8 ± 0.2 (P<0.05) compared to the group treated with lidocaine 1.3±0.2 (P<0.01), both of them were efficacious for the treatment of VT
