Timing of percutaneous coronary intervention in troponin-negative patients with acute coronary syndrome without persistent ST-segment elevation: prel…

2015

OBJECTIVE Management of acute coronary syndromes without persistent ST-segment elevation (NSTE-ACS) and unstable angina pectoris (UAP) remains challenging. The study aimed to analyze the current management of UAP patients in German chest pain units focussing on the different time lines of invasive strategy. METHODS A total of 1400 UAP patients admitted to a certified chest pain unit were enrolled. Analyses of high-risk criteria with indication for invasive management and of 3-month clinical outcomes were performed by subgrouping UAP patients to immediate and early invasive (<8 hours), early elective invasive (8-24 hours), late elective invasive (24-72 hours) strategy, and without percutaneo…

[Relationship of C-reactive protein levels with angiographic findings and markers of necrosis in non-ST-segment elevation acute coronary syndrome].

2004

The mechanism responsible for elevated C-reactive protein levels (inflammation of the ruptured atherosclerotic plaque or myocardial necrosis) in acute coronary syndromes is controversial. The aim of this study was to investigate the relationship between C-reactive protein levels and angiographic complexity of the culprit lesion and troponin elevation in patients with non-ST elevation acute coronary syndromes.The study group consisted of 125 patients with single-vessel disease. Troponin-I and C-reactive protein were measured, and the complexity of the culprit lesion was analyzed (TIMI flow and thrombus). Information on age, sex, smoking habit, hypertension, hypercholesterolemia and diabetes …

Prognosis and Management of Acute Coronary Syndrome in Spain in 2012: The DIOCLES Study

2015

Abstract Introduction and objectives To identify the current mortality and management of patients admitted for suspected acute coronary syndrome in Spain. The last available registry (2004-2005) reported an in-hospital mortality of 5.7%. Methods The study included patients consecutively admitted between January and June 2012 at 44 hospitals selected at random. Information was collected on clinical course at admission and on events at 6 months. Results A total of 2557 patients admitted with suspected acute coronary syndrome were included: 788 (30.8%) with ST-segment elevation, 1602 (62.7%) without ST-segment elevation, and 167 (6.5%) with unclassified acute coronary syndrome. In-hospital mor…

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…

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 …

CT angiography versus intraarterial digital subtraction angiography for assessment of aortoiliac occlusive disease.

1997

The purpose of this study was to evaluate the accuracy of CT angiography (CTA) with a single helical acquisition for assessment of stenoses and occlusions of the iliac arteries.In our prospective study, intraarterial digital subtraction angiography and IV CTA were performed from the suprarenal aorta to below the femoral bifurcation in 30 patients with vascular occlusive disease. Maximum-intensity-projection images in multiple views were also obtained. The accuracy of CTA with and without analysis of axial images was determined.Sensitivity and specificity of CTA were 100% for iliac artery occlusions with a confidence interval 85-100% and 97-100%, respectively. When axial scans were interpret…

Computed Tomography-Aortography Versus Color-Duplex Ultrasound for Surveillance of Endovascular Abdominal Aortic Aneurysm Repair: A Prospective Multi…

2020

Background Color-duplex ultrasonography (DUS) could be an alternative to computed tomography-aortography (CTA) in the lifelong surveillance of patients after endovascular aneurysm repair (EVAR), but there is currently no level 1 evidence. The aim of this study was to assess the diagnostic accuracy of DUS as an alternative to CTA for the follow-up of post-EVAR patients. Methods Between December 16, 2010, and June 12, 2015, we conducted a prospective, blinded, diagnostic-accuracy study, in 15 French university hospitals where EVAR was commonly performed. Participants were followed up using both DUS and CTA in a mutually blinded setup until the end of the study or until any major aneurysm-rel…

Prevalence and characteristics of coronary artery disease in a population with suspected ischaemic heart disease using CT coronary angiography: corre…

2008

Purpose. This study was undertaken to describe the correlation between the distribution of coronary artery disease (CAD) in a symptomatic population with suspected ischaemic heart disease, cardiovascular risk factors (RF) and clinical presentation. Materials and methods. We studied 163 patients (mean age 65.5 years; 101 men and 62 women) referred for multidetector computed tomography coronary angiography (MDCT-CA) to rule out CAD. The patients had no prior history of revascularisation or myocardial infarction. We analysed how the characteristics of CAD (severity and type of plaque) can change with the increase in RF and how they are related to different clinical presentations. Results. Pati…

Randomized comparison between the invasive and conservative strategies in comorbid elderly patients with non-ST elevation myocardial infarction.

2016

Abstract Background Comorbid elderly patients with non-ST-elevation myocardial infarction (non-STEMI) are underrepresented in randomized trials and undergo fewer cardiac catheterizations according to registries. Our aim was to compare the conservative and invasive strategies in these patients. Methods Randomized multicenter study, including 106 patients (January 2012–March 2014) with non-STEMI, over 70 years and with comorbidities defined by at least two of the following: peripheral artery disease, cerebral vascular disease, dementia, chronic pulmonary disease, chronic renal failure or anemia. Patients were randomized to invasive (routine coronary angiogram, n = 52) or conservative (coronar…
