The best revascularization strategy (complete vs incomplete revascularization) in patients with ST-elevation myocardial infarction (STEMI) is still debated. The interaction between gender and revascularization strategy in patients with STEMI on all-cause mortality is uncertain. The aim of the present study was to evaluate gender-specific difference in all-cause mortality between incomplete and complete revascularization in patients with STEMI and multi-vessel coronary artery disease.

To establish which strategy should be followed, survival rates over a longer period should be evaluated. The aim of this study was to investigate whether complete revascularisation, compared with incomplete revascularisation, is associated with reduced short-term and long-term all-cause mortality in patients with first STEMI and multivessel CAD.

The presence of a left dominant coronary artery system is associated with worse outcome after ST-segment elevation myocardial infarction (STEMI) compared with right dominance or a balanced coronary artery system. However, the association between coronary arterial dominance and left ventricular (LV) function at follow-up after STEMI is unclear. The present study aimed at evaluating the relation between coronary arterial dominance and LV ejection fraction (LVEF) shortly after STEMI and at 12-month follow-up.

Methods And Results: Coronary angiographic images of consecutive patients presenting with first STEMI were retrospectively reviewed to assess coronary vessel dominance.
The simultaneous occurrence of cancer and coronary heart disease is increasing in the Western world. Nevertheless, the influence of cancer on ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) has not been investigated extensively. This multicenter registry included patients with STEMI treated with primary PCI from 2006 to 2009.

Therefore, the incidence, determinants, and prognostic implications of in-hospital major bleeding after primary percutaneous coronary intervention for STEMI were investigated. In 963 consecutive patients, the incidence of bleeding was evaluated according to commonly used classifications including Can Rapid risk stratification of Unstable angina patients Suppress Adverse outcomes with Early implementation of the ACC/AHA guidelines, Thrombolysis In Myocardial Infarction, Global Use of Strategies To Open coronary arteries, and Bleeding Academic Research Consortium.

As a specific indicator of myocardial necrosis, cardiac troponin T (cTnT) can be used as a surrogate measure for this purpose. The present study sought to investigate the use of peak and serial 6-hour fixed-time high-sensitive (hs) cTnT for estimation of infarct size, left ventricular (LV) function, and prognosis in consecutive patients with ST-segment elevation myocardial infarction.

Methods And Results: The current analysis of a prospective registry included consecutive patients treated with EES or E-ZES for STEMI.
Previous studies investigating the influence of gender on ST-segment elevation myocardial infarction have reported conflicting results. The aim of this study was to assess the influence of gender on ischemic times and outcomes after ST-segment elevation myocardial infarction in patients treated with primary percutaneous coronary intervention in modern practice. The present multicenter registry included consecutive patients with ST-segment elevation myocardial infarctions treated with primary percutaneous coronary intervention at 3 hospitals.

Multiple genetic polymorphisms have been related to antiplatelet resistance by several large trials, however data from common clinical practice is limited. We examined the influence of previously described polymorphisms, related to aspirin and clopidogrel resistance, on treatment outcome in a real life unselected population of patients presenting with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention.

During the past decade, advances in software and hardware have allowed co-registration of various imaging modalities, resulting in cardiac 'hybrid' or 'fusion' imaging. In this Review, we discuss the roles of both multimodality and hybrid imaging in three broad areas of cardiology--coronary artery disease (CAD), heart failure, and valvular heart disease.

Methods And Results: After five years, 310 STEMI patients randomly assigned to implantation of either SES or BMS, were compared. Survival rates were comparable between groups (SES 94.
High Asymmetric Dimethylarginine (ADMA) levels are associated with increased platelet activity, elevated blood pressure, vasoconstriction and impaired vascular relaxation. We hypothesized that the myocardial infarction morning peak of occurrence is closely related to a morning peak of ADMA levels. We performed a cross-sectional study among patients with documented myocardial infarction who had been enrolled in the prospective MISSION! Intervention Study.
View Article and Find Full Text PDFLate-acquired stent malapposition (LASM) is a common finding after sirolimus-eluting stent (SES) implantation and may be the cause for late stent thrombosis. Inflammation may play a pivotal role in LASM just as it plays in stent restenosis. We have therefore investigated seven polymorphisms involved in inflammatory processes, related in previous reports to restenosis, on the risk of LASM in SES patients.

Intervention Study: A Prospective Randomised Controlled Trial to Evaluate the Efficacy of Drug-Eluting Stents Versus Bare-Metal Stents for the Treatment of Acute Myocardial Infarction after a median follow-up period of 38 months.

Methods And Results: Clinical, angiographic, intravascular ultrasound (lVUS) and virtual histology (VH)-IVUS results were obtained and analysed in 20 SES and 20 BMS AMI patients at the index procedure and at nine months follow-up. Quantitative angiography and IVUS showed a trend toward decreases in mean lumen diameter, vessel volume, minimum lumen area and mean lumen area at both stent edges of BMS, and at the proximal edge of SES.
Objectives: Stent thrombosis is a life-threatening complication associated with sudden death and acute myocardial infarction. Histopathologic studies have linked the occurrence of very late stent thrombosis in drug-eluting stents (DES) with delayed endothealisation and stent malapposition. Our aim was to investigate if late stent malapposition in DES could be predicted by immediate postintervention intra-vascular ultrasonography (IVUS).

Methods And Results: Patients were treated according to the MISSION! protocol. The protocol encompasses pre-hospital, in-hospital, and outpatient clinical framework for the acute and chronic treatment of AMI patients and the decision making regarding primary prevention of sudden cardiac death (SCD).
Objectives: Acute and late stent malapposition (SM) after bare-metal stents (BMS) and sirolimus-eluting stents (SES) in ST-segment elevation myocardial infarction patients were studied.
Background: Stent thrombosis may be caused by SM after primary percutaneous coronary intervention in ST-segment elevation myocardial infarction patients.
Methods: Post-procedure and follow-up intravascular ultrasound data were available in 184 out of 310 patients (60%; 104 SES, 80 BMS) included in the MISSION! Intervention Study.
PAI-1 expression is regulated by a 4G/5G promoter polymorphism. The 4G allele is associated with greater circadian variation of PAI-1 levels. We hypothesized that the 24 h variation of cardiac risk is more pronounced among persons with the 4G4G genotype than among ones with 4G5G and 5G5G genotypes.
View Article and Find Full Text PDFBackground: Recent concerns have emerged on the potential higher risk of stent thrombosis after DES implantation, that might be even more pronounced among STEMI patients. The aim of the current study was to perform a meta-analysis to evaluate the benefits and safety of Sirolimus-Eluting Stent (SES) as compared to BMS in patients undergoing primary angioplasty for STEMI.
Methods: The literature was scanned by formal searches of electronic databases (MEDLINE and CENTRAL).
Aims: Late stent malapposition (LSM) may be acquired (LASM) or persistent. LSM may play a role in patients who develop late stent thrombosis (ST). Our objective was to compare the risk of LASM in bare metal stents (BMS) with drug-eluting stents (DES) and to investigate the possible association of both acquired and persistent LSM with (very) late ST.

Plasma of 44 patients with acute myocardial infarction (AMI) and 22 controls were profiled for a panel of chemokines by multiplex analysis. Levels of CCL3 were prospectively verified in 54 patients with unstable angina pectoris (UAP).
