Pretreatment with prasugrel in non-ST-segment elevation acute coronary syndromes

2013

Item does not contain fulltext BACKGROUND: Although P2Y12 antagonists are effective in patients with non-ST-segment elevation (NSTE) acute coronary syndromes, the effect of the timing of administration--before or after coronary angiography--is not known. We evaluated the effect of administering the P2Y12 antagonist prasugrel at the time of diagnosis versus administering it after the coronary angiography if percutaneous coronary intervention (PCI) was indicated. METHODS: We enrolled 4033 patients with NSTE acute coronary syndromes and a positive troponin level who were scheduled to undergo coronary angiography within 2 to 48 hours after randomization. Patients were randomly assigned to recei…

Prognostic value of plasma tissue factor and tissue factor pathway inhibitor for cardiovascular death in patients with coronary artery disease: the A…

2007

Summary. Background: Tissue factor (TF) and its specific inhibitor, tissue factor pathway inhibitor (TFPI), are important contributors to the initiation of the coagulation process. Objectives: To compare plasma levels of soluble TF (sTF) and free-TFPI (f-TFPI) between patients with stable angina pectoris (SAP) and acute coronary syndrome (ACS) and to assess the impact of the two variables on long-term prognosis. Patients/methods: Patients with SAPs (n = 1146) and acute coronary syndrome (n = 523) from the AtheroGene study were included and followed for 2.3 years. Because of the strong impact of unfractionated heparin (UFH) on f-TFPI levels, but not on sTF levels, patients having received UF…

Prognostic role of aldosterone in patients with acute coronary syndrome: short and medium term follow-up.

2013

AIMS: Different studies have shown a correlation between aldosterone, atherosclerosis and ischemia in the past decade. Evidence exists for the relationship between high levels of aldosterone and augmented risk of cardiovascular diseases, such as hypertension, cardiac failure, coronary artery disease and stroke. The objective of this study was to determine the prognostic role of aldosterone in patients with myocardial infarction. METHODS: The study population included 96 consecutive patients admitted to our department for ST-elevated and non-ST-elevated myocardial infarction from June 2009 to March 2012. Plasma aldosterone levels were measured at admission to hospital in all patients. A 2-ye…

Differential Prognostic Effect of Revascularization According to a Simple Comorbidity Index in High-Risk Non-ST-Segment Elevation Acute Coronary Synd…

2011

Background: Data on the effect of revascularization on outcome in patients with high-risk non–ST-segment elevation acute coronary syndrome (NSTEACS) and significant comorbidities are scarce. Recently, a simple comorbidity index (SCI) including 5 comorbidities (renal failure, dementia, peripheral artery disease, heart failure, and prior myocardial infarction [MI]) has shown to be a useful tool for risk stratification. Nevertheless, therapeutic implications have not been derived. Hypothesis: We sought to evaluate the prognostic effect attributable to revascularization in NSTEACS according the SCI score. Methods: We included 1017 consecutive patients with NSTEACS. The effect of revascularizati…

High levels of N-terminal pro B-type natriuretic peptide are associated with ST resolution failure after reperfusion for acute myocardial infarction

2007

Background: B-type natriuretic peptide and the N-terminal fragment of its prohormone, N-terminal pro-brain natriuretic peptide (Nt-proBNP), provide valuable prognostic information on short- and long-term mortality in patients with acute coronary syndrome Aim: To investigate the association between plasma NT-proBNP levels and ST-segment resolution (STR) after reperfusion in patients with ST-segment elevation myocardial infarction (STEMI). Methods: Consecutive patients from the French regional RICO survey with STEMI who were treated by primary PCI or lysis <12 h were included. Blood sample was taken on admission to measure plasma NT-proBNP. Maximal ST segment elevation was measured on the sin…

An Invasive Strategy in Non-ST-Segment Elevation Acute Coronary Syndromes. From Large Trials to the Real World

2004

Introduction and objectives We report the impact on prognosis of an invasive strategy used at our center for non-ST-segment elevation acute coronary syndrome. Patients and method We analyzed 504 consecutive patients with typical chest pain, electrocardiographic changes or increased troponin I serum values, who were divided into 2 cohorts: a ) conservative group, 272 patients admitted between October 2001 and September 2002 and managed with a conservative strategy, and b ) invasive group, 232 patients admitted between October 2002 and September 2003 for whom an invasive strategy was recommended. We recorded major events (death or reinfarction) and minor events (readmission or need for post-d…

Incidence, Predictors, and Impact on Six-Month Mortality of Three Different Definitions of Contrast-Induced Acute Kidney Injury After Coronary Angiog…

2017

We assessed incidence, predictors, and impact on 6-month mortality of contrast-induced acute kidney injury (CI-AKI) after coronary angiography with or without percutaneous coronary intervention in patients with acute coronary syndrome (ACS), according to 3 different CI-AKI definitions. Serum creatinine (sCr) was assessed at baseline and 48 to 72 hours after procedure to classify patients into 3 CI-AKI groups: Group 1: increase in sCR ≥25% over baseline but absolute increase 25% in the remaining 844 (84.2%). CI-AKI was significantly associated with 6-month all-cause mortality using the definitions for Group 2 (hazard ratio 3.1, 95% confidence interval [CI] 1.5 to 6.6, p = 0.002) and Group 3 …

Association of adiponectin with adverse outcome in coronary artery disease patients: results from the AtheroGene study

2008

In primary prevention, the adipocytokine adiponectin seems to be protective against diabetes mellitus and cardiovascular disease. Data in patients with manifest coronary artery disease (CAD) are scant stimulating the investigation of the association of adiponectin concentrations and cardiovascular outcome in a prospective CAD cohort.In 1890 consecutive patients with documented CAD [1130 with stable angina (SAP) and 760 with acute coronary syndrome (ACS)] baseline concentrations of adiponectin were measured by enzyme-linked immuno assay. During a median follow-up of 2.5 years cardiovascular events were registered (cardiovascular deaths 70; non-fatal myocardial infarction 46). Baseline adipon…

Effects of canrenoate plus angiotensin-converting enzyme inhibitors versus angiotensin-converting enzyme inhibitors alone on systolic and diastolic f…

2004

Background Aldosterone (ALDO) exerts profibrotic effects, acting via the mineralocorticoid receptors in cardiovascular tissues. Aldosterone antagonism in combination with angiotensin-converting enzyme inhibition may better protect against the untoward effects of ALDO than angiotensin-converting enzyme inhibition alone. Methods In a double-blind randomized study, the tolerability and efficacy of canrenoate (25 mg/d) plus captopril versus captopril alone were evaluated in 510 patients with an acute anterior myocardial infarction (MI), a serum creatinine concentration 5.5 mEq/L and creatinine levels to >2.0 mg/L after 10 days of treatment were observed. At 180 days, the mitral E-wave–A-wave ra…
