- 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.

- Sudden cardiac death (SCD) remains a daunting problem. It is a major public health issue for several reasons: from its prevalence (20% of total mortality in the industrialized world) to the devastating psycho-social impact on society and on the families of victims often still in their prime, and it represents a challenge for medicine, and especially for cardiology. This text summarizes the discussions and opinions of a group of investigators with a long-standing interest in this field. We addressed the occurrence of SCD in individuals apparently healthy, in patients with heart disease and mild or severe cardiac dysfunction, and in those with genetically based arrhythmic diseases. Recognizing the need for more accurate registries of the global and regional distribution of SCD in these different categories, we focused on the assessment of risk for SCD in these four groups, looking at the significance of alterations in cardiac function, of signs of electrical instability identified by ECG abnormalities or by autonomic tests, and of the progressive impact of genetic screening. Special attention was given to the identification of areas of research more or less likely to provide useful information, and thereby more or less suitable for the investment of time and of research funds.

- Objectives: Pentraxin 3 (PTX3) is the prototype of the long pentraxin family. PTX3 is involved in inflammatory processes affecting the cardiovascular system, and PTX3 levels have been shown to be elevated and independently prognostic in ST-elevation myocardial infarction. Data on PTX3 levels in non-ST-elevation acute coronary syndrome (NSTE-ACS), in contrast, are limited. The aim of the present analysis was to investigate the implications of PTX3 levels in a fairly large sample of NSTE-ACS patients and in comparison to levels of C-reactive protein (CRP). Design and methods: We measured levels of PTX3 and CRP in both 82 healthy controls and 401 NSTE-ACS patients from the GUSTO IV study, and studied the associations of these biomarkers to clinical data and 1-year mortality. Results: NSTE-ACS patients had significantly higher median PTX3 levels compared to healthy controls (3.8 vs. 1.9 mu g/L; p < 0.001). PTX3 levels in patients with NSTE-ACS were independently related to female sex and cardiac troponin T levels, but not to age or cardiovascular risk factors. PTX3 levels were higher in patients who died within 1 year but did not emerge as an independent predictor of 1-year mortality (adjusted OR 1,2 [95% Cl 0.6-2.31). This was in contrast to CRP (adjusted OR 1.5 [95% Cl 1.1-2.3]). Neither PTX3 nor CRP yielded significant discriminative value regarding mortality prediction. Conclusions: PTX3 levels are elevated in NSTE-ACS. However, the prognostic information provided by PTX3 levels is limited and inferior compared to CRP. Our data, thus, do not support the measurement of PTX3 in patients with NSTE-ACS.

- BACKGROUND: ST2 is a member of the interleukin-1 receptor family that is up-regulated in conditions associated with increased myocardial strain. ST2 has been shown to be independently predictive of adverse outcome in heart failure and ST-segment elevation myocardial infarction, but its prognostic value in non-ST-elevation acute coronary syndrome (NSTE-ACS) has not been established. METHODS: We measured ST2 at randomization and after 24, 48, and 72 hours in 403 NSTE-ACS patients from the GUSTO IV study, and studied its kinetics and its associations to clinical baseline factors and 1-year mortality. RESULTS: Median ST2 levels decreased from 28.4 U/mL at randomization to 21.8 U/mL at 72 hours (P < .001). Peak levels were noted 6 to 17 hours after symptom onset. Randomization ST2 levels were independently associated to N-terminal pro-B-type natriuretic peptide but otherwise exhibited only weak relations to cardiovascular risk factors and comorbidities, and biomarkers of myocardial necrosis or inflammation. ST2 was related to 1-year mortality independently of clinical risk indicators (odds ratio 2.3 [95% CI 1.1-4.6], P = .03) but lost its predictive value after additional adjustment for prognostic biomarkers, in particular N-terminal pro-B-type natriuretic peptide. CONCLUSIONS: ST2 levels are elevated early in NSTE-ACS and predict 1-year mortality. Our data indicate that ST2 represents an interesting novel pathophysiologic pathway in the setting of ischemia-related myocardial dysfunction. However, future prospective evaluations in larger populations are needed before the clinical utility of ST2 can be determined.
