Combined strategy of upfront CTCA and optimal treatment for stable chest pain: rationale and design of the CLEAR-CAD trial.

Background: Patients with stable chest pain suspected of coronary artery disease (CAD) usually undergo multiple diagnostic tests to confirm or rule out obstructive CAD. Some tests may not effectively assess the presence of CAD, precluding optimal treatment. A diagnostic strategy of upfront computed tomography coronary angiography (CTCA) combined with optimal medical therapy (OMT) tailored to the extent of CAD may be superior to standard care in preventing major adverse cardiac events.

Comparison of Outcomes and Intervention Among Patients With Non-ST-Segment Elevation Acute Myocardial Infarction of Those With a Left Circumflex Versus Those With a Non-Left Circumflex-Related Coronary Artery (From the ELISA-3 Trial).

Previous studies found that patients with an acute coronary syndrome (ACS) due to occlusion of the left circumflex (LC) coronary artery often present without ST-elevation, leading to a delay in diagnosis and revascularization, a larger infarct size, and a worse prognosis. In this subgroup analysis of the ELISA-3 study (early or late intervention in high-risk non-ST-segment elevation acute coronary syndromes [NSTE-ACS]) incidence, characteristics and prognosis of LC-related NSTE-ACS was investigated, and the outcome of early versus late invasive strategy was compared. In 383 of 542 patients the culprit vessel could be identified, with the LC artery in 112 (29%) of them.

Two-year outcome after early or late Intervention in non-ST elevation acute coronary syndrome.

Objective: To compare long-term outcome of an early to a delayed invasive strategy in high-risk patients with non-ST elevation acute coronary syndrome (NSTE-ACS).

Methods: This prospective, multicentre trial included patients with NSTE-ACS and at least two out of three of the following high-risk criteria: (1) evidence of extensive myocardial ischaemia on ECG, (2) elevated biomarkers for myocardial necrosis and (3) age above 65 years. Patients were randomised to either an early (angiography and revascularisation if appropriate <12 hours) or a delayed invasive strategy (>48 hours after randomisation).

Early or late intervention in patients with transient ST-segment elevation acute coronary syndrome: Subgroup analysis of the ELISA-3 trial.

Objectives: To investigate incidence and patient characteristics of transient ST-segment elevation (TSTE) ACS and to compare outcome of early versus late invasive treatment.

Background: Optimal timing of treatment in TSTE-ACS patients is not outlined in current guidelines and no prospective randomized trials have been done so far.

Methods: Post hoc subgroup analysis of patients with TSTE randomized in the ELISA 3 trial.

Early or late intervention in high-risk non-ST-elevation acute coronary syndromes: results of the ELISA-3 trial.

Aims: To compare an early to a delayed invasive strategy in high-risk patients with NSTE-ACS.

Methods And Results: In this prospective multicentre trial, 542 patients hospitalised with NSTE-ACS were randomised to either an immediate (angiography and revascularisation if appropriate <12 hr) or a delayed invasive strategy (>48 hr after randomisation). Patients were eligible if they had two of the following three high-risk characteristics: evidence of extensive myocardial ischaemia on ECG, elevated biomarkers for myocardial necrosis (TropT >0.
