Abstract
Aims:
The pattern of coronary occlusion might contribute to the onset of ventricular arrhythmia and sudden cardiac death (SCD). We hypothesized that the concentrations of microparticles might differ between SCD and ST-elevation myocardial infarction (STEMI) patients without rhythmic disturbances.
Methods and results:
The study sample includes consecutive patients hospitalized in two French tertiary centres between 2006 and 2011 for SCD with angiographically-proven acute coronary occlusion (
After multivariate analysis, intracoronary concentrations of endothelial-derived microparticles were significantly higher in SCD than in STEMI patients (129 (74–185)
Conclusion:
The higher concentrations of endothelial-derived microparticles in SCD due to acute coronary occlusion compared with STEMI without rhythmic disturbances suggests different patterns of acute coronary occlusion.
