| Abstract |
Prognostic implication of right ventricular dysfunction and infarction scar in the chronic phase of the myocardial infarction has been little analyzed. In 299 consecutive patients (age 63 ± 11 years) with >3 months old myocardial infarction, we quantified right and left ventricular volumes and ejection fractions by cine cardiac magnetic resonance, and right and left ventricular scar tissue by late gadolinium enhancement. During follow-up (median, 2.4 years) cardiac events (cardiac-related deaths or appropriate intra-cardiac defibrillator shocks) occurred in 21 patients. Right ventricular systolic dysfunction (ejection fraction lower the reference mean values-2 SD) was present in 67 patients (22 %), right ventricular late gadolinium enhancement was observed in 15 patients (5 %). After adjustment for left ventricular end-diastolic volume, wall motion score index, and global extent of late gadolinium enhancement, right ventricular dysfunction was an independent and incremental predictor of cardiac events (p = 0.0053), while right ventricular scar tissue extent was not. Right ventricular dysfunction is an independent and incremental predictor of cardiac events also in the chronic phase of the myocardial infarction. In these patients, right ventricular dysfunction does not necessarily mean right ventricular infarction scar, but likely reflects the effects of hemodynamic and biohumoral factors. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 November 2015.
All research outputs
#19,944,091
of 25,373,627 outputs
Outputs from The International Journal of Cardiovascular Imaging
#1,116
of 2,012 outputs
Outputs of similar age
#188,733
of 274,073 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#14
of 40 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,012 research outputs from this source. They receive a mean Attention Score of 2.3. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 274,073 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 40 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
