Abstract

Predictors of left ventricular reverse remodeling (LVRR) after therapy with angiotensin converting enzyme inhibitors or angiotensin-receptor blockers and β blockers in patients with idiopathic dilated cardiomyopathy (IDC) remains unclear. We studied 44 patients with IDC who had been treated with the therapy. LVRR was defined as LV end-diastolic dimension ≤ 55 mm and fractional shortening ≥ 25% at the last echocardiogram. During a mean follow-up period of 4.7 ± 3.3 years, LVRR occurred in 34% (15/44) of the patients. We divided the patients into 2 groups: (1) patients with LVRR (n = 15); (2) patients without LVRR (n = 29). The presence of atrial fibrillation was 40% in patients with LVRR and 14% in those without (p = 0.067). Initial LV end-diastolic dimension was significantly smaller (62 ± 6 vs. 67 ± 6 mm, p = 0.033) in patients with LVRR than in those without. Initial LV end-diastolic dimension of 63.5 mm was an optimal cutoff value for predicting LVRR (sensitivity: 67%, specificity: 59%, area under the curve: 0.70, p = 0.030). When patients were further allocated according to initial LV end-diastolic dimension ≤ 63.5 mm with atrial fibrillation, the combined parameter was a significant predictor of LVRR by univariate logistic regression analysis (odds ratio, 5.78, p = 0.030) (sensitivity: 33%, specificity: 97%, p = 0.013). Combined information on LV end-diastolic dimension and heart rhythm at diagnosis is useful in predicting future LVRR in patients with IDC.

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 25 March 2015.
All research outputs
#2,612,033
of 4,921,996 outputs
Outputs from Cardiovascular Ultrasound
#95
of 159 outputs
Outputs of similar age
#83,884
of 145,617 outputs
Outputs of similar age from Cardiovascular Ultrasound
#16
of 17 outputs
Altmetric has tracked 4,921,996 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 159 research outputs from this source. They receive a mean Attention Score of 2.5. This one is in the 20th percentile – i.e., 20% 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 145,617 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
