To test whether remote ischaemic conditioning (RIC) as adjuvant to standard of care (SOC) would prevent progression towards heart failure (HF) after ST-elevation myocardial infarction (STEMI). Single-centre parallel 1:1 randomized trial (computerized block-randomization, concealed allocation) to assess superiority of RIC (3 cycles of intermittent 5 min lower limb ischaemia) over SOC in consecutive STEMI patients (NCT02313961, clinical trials.gov). From 258 patients randomized to RIC or SOC, 9 and 4% were excluded because of unconfirmed diagnosis and previously unrecognized exclusion criteria, respectively. Combined primary outcome of cardiac mortality and hospitalization for HF was reduced in RIC compared with SOC (n = 231 and 217, respectively; HR = 0.35, 95% CI 0.15-0.78) as well as each outcome in isolation. No difference was found in serum troponin I levels between groups. Median and maximum follow-up time were 2.1 and 3.7 years, respectively. In-hospital HF (RR = 0.68, 95% CI 0.47-0.98), need for diuretics (RR = 0.68, 95% CI 0.48-0.97) and inotropes and/or intra-aortic balloon pump (RR = 0.17, 95% CI 0.04-0.76) were decreased in RIC. On planned 12 months follow-up echocardiography (n = 193 and 173 in RIC and SOC, respectively) ejection fraction (EF) recovery was enhanced in patients presenting with impaired left ventricular (LV) function (10% absolute difference in median EF compared with SOC; P < 0.001). In addition to previously reported improved myocardial salvage index and reduced infarct size RIC was shown beneficial in a combined hard clinical endpoint of cardiac mortality and hospitalization for HF. Improved EF recovery was also documented in patients with impaired LV function.

Purpose -The purpose of this paper is to identify development strategies for Business Tourism in territories where this segment is not always given due consideration, especially at the level of local and regional development policies. Design -The paper discusses the concepts of Business Tourism and analyses the characteristics of a delimited territory in the Central Region of Portugal that encompasses the cities of Coimbra, Aveiro and Viseu, located between the main Portuguese cities, Lisbon and Oporto. Methodology -A Delphi study was conducted to explore the prospects of destination stakeholders, with the aim of identifying proposals and product development measures in this territory. Findings -Despite the lower urban density and lower load capacity, when compared with the main urban centres of Lisbon and Oporto, this territory presents a qualified and diverse tourism offer that combined with the existence of differentiated venues and quality accommodation can contribute to provide a valued tourism experience associated with the Meetings Industry. Originality -The study presented here allows us to reflect on the potential of Business Tourism in territories with lower urban density and lower supply of facilities and services, when compared to the major cities that usually take the leading positions in international rankings. This is especially true, if we consider that smaller urban centres that are relatively near each other (as is the case of Coimbra, Aveiro and Viseu) may find interesting strategic advantages in joint action, taking into account that these three geographic areas complement each other in the integrated supply of tourism products, experiences, services and facilities.

Introduction: Atrial fibrillation (AF) is widely recognized as an adverse prognostic factor during acute myocardial infarction, although the impact of AF type ---new-onset (nAF) or pre-existing (pAF) ---is still controversial. Objectives: To identify the clinical differences and prognosis of nAF and pAF during acute coronary syndromes (ACS). Methods: We performed a retrospective observational cohort study including 1373 consecutive patients (mean age 64 years, 77.3% male) admitted to a single center over a three-year period, with a six-month follow-up. Results: AF rhythm was identified in 14.5% patients, of whom 71.4% presented nAF and 28.6% pAF. When AF types were compared, patients with nAF more frequently presented with STelevation ACS (p=0.003). Patients with pAF, in turn, were older (p=0.032), had greater left atrial diameter (p=0.001) and were less likely to have significant coronary lesions (p=0.034). Regarding therapeutic strategy, nAF patients were more often treated by rhythm control during hospital stay (p<0.001) and were less often anticoagulated at discharge (p=0.001). Compared with the population without AF, nAF was a predictor of death during hospital stay in univariate (p<0.001) and multivariate analysis (OR 2.67, p=0.047), but pAF was not. During follow-up, pAF was associated with higher mortality (p=0.014), while nAF patients presented only a trend towards worse prognosis. Conclusions: AF during the acute phase of ACS appears to have a negative prognostic impact only in patients with nAF and not in those with pAF. 2174-2049Document downloaded from http://www.elsevier.pt, day 01/07/2015.

Aims  The aim of this study was to determine the contemporary use of reperfusion therapy in the European Society of Cardiology (ESC) member and affiliated countries and adherence to ESC clinical practice guidelines in patients with ST-elevation myocardial infarction (STEMI). Methods and results  Prospective cohort (EURObservational Research Programme STEMI Registry) of hospitalized STEMI patients with symptom onset &lt;24 h in 196 centres across 29 countries. A total of 11 462 patients were enrolled, for whom primary percutaneous coronary intervention (PCI) (total cohort frequency: 72.2%, country frequency range 0–100%), fibrinolysis (18.8%; 0–100%), and no reperfusion therapy (9.0%; 0–75%) were performed. Corresponding in-hospital mortality rates from any cause were 3.1%, 4.4%, and 14.1% and overall mortality was 4.4% (country range 2.5–5.9%). Achievement of quality indicators for reperfusion was reported for 92.7% (region range 84.8–97.5%) for the performance of reperfusion therapy of all patients with STEMI &lt;12 h and 54.4% (region range 37.1–70.1%) for timely reperfusion. Conclusions  The use of reperfusion therapy for STEMI in the ESC member and affiliated countries was high. Primary PCI was the most frequently used treatment and associated total in-hospital mortality was below 5%. However, there was geographic variation in the use of primary PCI, which was associated with differences in in-hospital mortality.

Takotsubo syndrome (TTS) is an acute, reversible cardiomyopathy. The central autonomic nervous system (ANS) is believed to play a role in this disease. The aim of the present study was to investigate the patterns of brain functional connectivity in a sample of patients who had experienced a previous episode of TTS. Brain functional connectivity, both at rest and in response to the stressful stimulus of topical cold stimulation, was explored using functional magnetic resonance imaging (fMRI), network-based statistics (NBS) and graph theory analysis (GTA) in a population consisting of eight patients with a previous episode of TTS and eight sex- and age-matched controls. At rest, a network characterized by increased connectivity in the TTS group compared to controls and comprising elements of the central ANS was identified. GTA revealed increased local efficiency, clustering and strength in regions of the bilateral hippocampus in subjects with a previous episode of TTS. When stressed by local exposure to cold, the TTS group differed significantly from both a pre-stress baseline interval and from the control group, showing increased connectivity in a network that included the left amygdala and the right insula. Based on the results, patients with TTS display a reorganization of cortical and subcortical networks, including areas associated with the emotional response and autonomic regulation. The findings tend to support the hypothesis that a deregulation of autonomic control at the central level plays a significant role in this syndrome.

MSI was shown to be a valuable bedside tool which can rapidly identify high-risk STEMI patients at presentation.
