Randomized Controlled Trial Comparative StudyComparison of manual thrombus aspiration with rheolytic thrombectomy in acute myocardial infarction.
Manual thrombus aspiration (MTA) is completely ineffective in 30% of cases, and the high profiles of the catheters prevent their use in tortuous and calcified vessels. The rheolytic thrombectomy (RT) device has the potential for improved thrombus removal in acute myocardial infarction as compared with MTA. No data exist on the comparison between the 2 techniques. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT01281033.

Randomized Controlled Trial Multicenter StudyRelationship between ST-segment recovery and clinical outcomes after primary percutaneous coronary intervention: the HORIZONS-AMI ECG substudy report.
In patients with ST-segment elevation myocardial infarction undergoing thrombolytic therapy, the degree of ST-segment resolution (STR) correlates with long-term cardiovascular mortality. The long-term predictive value of STR after primary percutaneous coronary intervention (PCI) is less well understood. We sought to determine the long-term prognostic value of STR after primary PCI in ST-segment-elevation myocardial infarction. ⋯ In this large international study, absent STR 60 minutes after primary PCI was present in ≈1 in 5 patients with ST-segment-elevation myocardial infarction and was a significant independent predictor of major adverse cardiovascular events and target vessel revascularization at 3 years.
