Drug therapy of paroxysmal atrial fibrillation in the elderly over 75 years old / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To investigate the effectiveness and safety of various agents on paroxysmal atrial fibrillation in the elderly over 75 years old.</p><p><b>METHODS</b>Totally 264 in-patients (75-91 years old, 185 males and 79 females) with atrial fibrillation history of less than 7 days were enrolled in this study. A total of 611 atrial fibrillation episodes were recorded, but 130 episodes (22.3%) of atrial fibrillation were auto-converted to sinus rhythm. The rest 481 episodes of atrial fibrillation were divided into six groups based on the drug used.</p><p><b>RESULTS</b>The cardioversion ratio of atrial fibrillation were 9.5%, 46.9%, 71.7%, 55.9%, 32.7%, and 73.6% in control, cedilanid, amiodarone, propafenone, verapamil, and quinidine groups, respectively. Ventricular rate control were 5.4%, 83.6%, 84.9%, 77.9%, 78.8%, and 11.3% in those groups, respectively. The total effective rates of amiodarone and cedilanid groups were the highest. When the ventricular rate was controlled to below 90 bpm, the patients would almost complain of no discomfort. No severe side-effect was observed in each group.</p><p><b>CONCLUSION</b>Amiodarone and cedilanid may be the proper drugs for the treatment of paroxysmal atrial fibrillation in the elderly. The above antiarrhythmics in each therapeutic group were relatively safe and effective.</p>

Intoxicaçäo digitálica: análise de 216 casos do HSE do Rio de Janeiro / Digitalis intoxication: review of 216 cases at the HSE of Rio de Janeiro

Foram revisados os prontuários de 216 pacientes do HSE do Rio de Janeiro que apresentavam intoxicaçäo digitálica e os resultados obtidos comparados com a literatura. Diversos parâmetros foram analisados, ressaltando-se que os mesmos foram correlacionados às drogas usadas. Houve maior incidência em pacientes do sexo masculino (81,93%), agrupados na faixa etária de 61 a 70 anos (34,72%). A insuficiência cardíaca estava presente em 67,12% dos pacientes. A droga mais utilizada foi digoxina (77,7%). As principais manifestaçöes clínicas foram: vômitos (53,24%), náuseas (52,77%) e descompensaçäo da insuficiência cardíaca (50%). A arritmia mais freqüêntemente encontrada foi extra-sístole ventricular multifocal (25,88%). Houve boa resposta à terapêutica conservadora em 86,11% dos pacientes, sendo que 2,78% evoluíram para o óbito
