- AIMS:Detailed data on patients admitted for acute myocardial infarction (AMI) on a European-wide basis are lacking. The Euro Heart Survey 2009 Snapshot was designed to assess characteristics, management, and hospital outcomes of AMI patients throughout European Society of Cardiology (ESC) member countries in a contemporary 'real-world' setting, using a methodology designed to improve the representativeness of the survey.METHODS:Member countries of the ESC were invited to participate in a 1-week survey of all patients admitted for documented AMI in December 2009. Data on baseline characteristics, type of AMI, management, and complications were recorded using a dedicated electronic form. In addition, we used data collected during the same time period in national registries in Sweden, England, and Wales. Data were centralized at the European Heart House.RESULTS:Overall, 4236 patients (mean age 66±13 years; 31% women) were included in the study in 47 countries. Sixty per cent of patients had ST-segment elevation myocardial infarction, with 50% having primary percutaneous coronary intervention and 21% fibrinolysis. Aspirin and thienopyridines were used in >90%. Unfractionated and low-molecular-weight heparins were the most commonly used anticoagulants. Statins, beta-blockers, and angiotensin-converting enzyme inhibitors were used in >80% of the patients. In-hospital mortality was 6.2%. Regional differences were observed, both in terms of population characteristics, management, and outcomes.CONCLUSIONS:In-hospital mortality of patients admitted for AMI in Europe is low. Although regional variations exist in their presentation and management, differences are limited and have only moderate impact on early outcomes.

- BACKGROUND: Ticagrelor, when compared with clopidogrel, reduced the 12-month risk of vascular death/myocardial infarction (MI) and stroke in patients with ST-elevation acute coronary syndromes (ST-E ACS) intended to undergo primary percutaneous coronary intervention (PCI) in the PLATelet inhibition and patient Outcomes (PLATO) trial. This pre-specified electrocardiogram (ECG) substudy explored whether ticagrelor's association with vascular death and MI within one year would be amplified by: 1) the extent of baseline ST shift; and 2) subsequently associated with less residual ST changes at hospital discharge. METHODS AND RESULTS: ECGs were evaluated centrally in a core laboratory in 3,122 ticagrelor- and 3,084 clopidogrel-assigned patients having at least 1mm ST-E in two contiguous leads as identified by site investigators on the qualifying ECG. Patients with greater ST-segment shift at baseline had higher rates of vascular death/MI within one year. Amongst those who also had an ECG at hospital discharge (n=4,798), patients with ≥50% ∑ST-deviation (∑ST-dev) resolution had higher event-free survival than those with incomplete resolution (6.4% vs. 8.8%, adjusted hazard ratio 0.69 (0.54-0.88), p=0.003). The extent of ∑ST-dev resolution was similar irrespective of treatment assignment. The benefit of ticagrelor versus clopidogrel on clinical events was consistent irrespective of the extent of baseline ∑ST-dev (p(interaction)=0.728). When stratified according to conventional times from symptom onset i.e. ≤3 hours, 3-6 hours, >6 hours, the extent of baseline ∑ST-dev declined progressively over time. As time from symptom onset increased beyond three hours, the benefit of ticagrelor appeared to be more pronounced; however, the interaction between time and treatment was not significant (p=0.175). CONCLUSIONS: Ticagrelor did not modify ∑ST-dev resolution at discharge nor was its benefit affected by the extent of baseline ∑ST-dev. These hypothesis-generating observations suggest that the main effects of ticagrelor may not relate to the rapidity or the completeness of acute reperfusion, but rather the prevention of recurrent vascular events by more powerful platelet inhibition or other mechanisms.
