Outcome associated with prescription of cardiac rehabilitation according to predicted risk after acute myocardial infarction: Insights from the FAST-MI registries.

Background: Cardiac rehabilitation is strongly recommended in patients after acute myocardial infarction.

Aims: To assess cardiac rehabilitation prescription after acute myocardial infarction according to predicted risk, and its association with 1-year mortality, using the FAST-MI registries.

Methods: We used data from three 1-month French nationwide registries, conducted 5 years apart from 2005 to 2015, including 13130 patients with acute myocardial infarction admitted to coronary or intensive care units.

Microvascular obstruction assessed by 3-tesla magnetic resonance imaging in acute myocardial infarction is correlated with plasma troponin I levels.

Background: Microvascular obstruction (MVO) at the acute phase of myocardial infarction (MI) is associated with poor prognosis. We aimed to evaluate the correlation between plasma cardiac troponin I (cTnI) at the acute phase of MI and extent of no-reflow, as assessed by 3-T cardiac magnetic resonance imaging (MRI). Secondly, we defined a cut-off value for cTnI predictive of no-reflow.

Invasive assessment of doubtful aortic stenosis by measuring simultaneous transaortic gradient with a pressure wire.

Two-dimensional transthoracic echocardiography (2D-TTE) is the reference technique for evaluating aortic stenosis (AS) but may be unreliable in some cases. We aimed to assess whether the use of a pressure wire to measure simultaneous transaortic gradient and aortic valve area (AVA) could be helpful in patients in whom initial noninvasive evaluations were considered doubtful for AS. Fifty-seven patients (mean age 76 years; 39 men) underwent cardiac catheterization with single arterial access for assessment of AVA with the Gorlin and Gorlin formula.

Effect of macroscopic-positive thrombus retrieval during primary percutaneous coronary intervention with thrombus aspiration on myocardial infarct size and microvascular obstruction.

Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention improves myocardial perfusion and survival; however, the effect of effective thrombus retrieval remains unclear. We evaluated whether macroscopic-positive TA in patients with ST-segment elevation myocardial infarction would reduce the infarct size (IS) and microvascular obstruction (MVO), as assessed by contrast-enhanced magnetic resonance imaging. A total of 88 patients with ST-segment elevation myocardial infarction were prospectively recruited and assigned to the TA-positive group (n = 38) or TA-negative group (n = 50) according to whether macroscopic aspirate thrombus was visible to the naked eye.

Recording of quality indicators in the management of acute coronary syndromes: predictors of reperfusion times.

Background: There is wide variation in recording of reperfusion times in the management of ST segment elevation acute coronary syndromes (ACS). We investigated factors that could predict time to reperfusion.

Methods: Single-centre, retrospective study of all consecutive patients admitted for primary PCI from June 2009 to October 2010.
