Key result
Cardiac magnetic resonance detected left ventricular thrombus in 12.3% of patients following acute STEMI, compared to 6.2% by standard two-dimensional echocardiography.
Why the study?
Left ventricular thrombus is a complication of acute STEMI, motivating an assessment of its incidence and predictors using serial cardiac magnetic resonance and two-dimensional echocardiography.
Does serial cardiac magnetic resonance (CMR) improve the detection of left ventricular thrombus compared to two-dimensional echocardiography in patients following acute STEMI?
Cohort (n=210)
Does serial cardiac magnetic resonance (CMR) improve the detection of left ventricular thrombus compared to two-dimensional echocardiography in patients following acute STEMI?
Absolute Event Rate: 12.3% vs 6.2%
CMR detects twice as many left ventricular thrombi as standard two-dimensional echocardiography in patients following acute STEMI, suggesting a role for targeted CMR screening in high-risk patients with anterior infarction and reduced LVEF.
No takes yet. Share an insight, caveat, or question.
LV thrombus incidence reaches 12% by serial CMR post-STEMI; leaves optimal screening and anticoagulation duration open.
Phan et al. (2019) conducted a cohort in Acute ST-segment elevation myocardial infarction (STEMI) (n=210). Cardiac magnetic resonance (CMR) vs. Two-dimensional echocardiography was evaluated on Incidence of left ventricular thrombus. Cardiac magnetic resonance detected left ventricular thrombus in 12.3% of patients following acute STEMI, compared to 6.2% by standard two-dimensional echocardiography.
