Synchronous Study: The Synchronous Study, which was sponsored by the Portuguese Institute of Heart Rhythm (IPRC) and included in its steering committee elements of the Echocardiography and Heart Failure Study Groups of the Portuguese Society of Cardiology, was an observational study of patients with left ventricular dysfunction and / or cardiac dyssynchrony with indication for implantation of electronic devices. It had the support of the consulting firm for scientific tests Key-point, the collaboration of the computer company Infortucano in the elaboration and operation of its database and the financial support by Boston-Scientific , through an unconditional Research Grant.
The study results were published in 2018 in the Portuguese Journal of Cardiology.
Portuguese Institute of Heart Rhythm (IPRC) was the sponsor of this study, with APAPE scientific collaboration, the sponsorship of Sanofi-Aventis Laboratory and the support of the Key-point Scientific Consulting firm, which helped define the study protocol and ensured its field implementation.
Having verified in a literature review that, regarding the prevalence of atrial fibrillation (AF), the numbers indicated by the different countries were very variable and no data were found for Portugal, we tried with the FAMA study to fill this lack of information. It would be important for us to improve the level of diagnosis and management of this arrhythmia in Portugal. On the other hand, the incidence of stroke and associated mortality is high in our country and it is not attributable only to traditional risk factors. We hypothesized the prevalence of AF may be related with this high incidence of stroke.
We studied the prevalence of AF in the population over 40 years, given the rarity of this arrhythmia before that age. We have collected data to try to characterize this arrhythmia in the Portuguese population, as well as the way it was being approached and treated among us. We chose to conduct an observational study based on a representative sample of the Portuguese population (over 10,000 individuals from all regions of the country) in which the existence of this arrhythmia was surveyed by performing a 12-lead ECG, while collecting demographic, socioeconomic, clinical and therapeutic data.
The study began on June 17, 2009 and was completed in December of the same year. The results were published in an article published in the Portuguese Journal of Cardiology.
