“…The fragmented QRS complex was an important marker for assuring the severity of infarction. However, another study reported that the Selvester QRS score is more accurate in estimating infarct volume than Q wave or fragmented QRS complexes in ischemic cardiomyopathy [26]. Scant data are available about the relationship between the QRS score and MO in acute MI patients.…”

“…Thus, there was a 34% prevalence of assessable high-risk ECGs parameters in this population ( Figure 3, right graph ). Not surprisingly given our experience with ischemic cardiomyopathy 28 , conduction delay abnormalities (prolonged QRSd and fQRS) were among the most prevalent parameters in the population, followed by arrhythmias (NSVT and PVCs) ( Figure 2) .…”

The electrocardiogram (ECG) can be used to predict cardiovascular risk; however, like all risk factors with imperfect specificity studies in low risk populations have been plagued by poor predictive accuracy. Although predictive accuracy might be improved among cohorts with a higher likelihood of cardiovascular events, this would also affect the prevalence of abnormal parameters and their exclusions. To determine the magnitude of these changes in a cohort with ischemic cardiomyopathy we analyzed 15 previously validated high-risk parameters from the resting and ambulatory ECG in subjects enrolled in the Prediction of ARrhythmic Events with Positron Emission Tomography (PAREPET) study (n=198). Using the published exclusion criteria from the validation studies (i.e. atrial fibrillation, persistent pacing, prolonged QRS), only 4 high-risk ECG parameters (27%) could be evaluated in all subjects and only 42% of subjects could have all 15 ECG parameters assessed. Nevertheless, almost every subject (97%) had at least one abnormal parameter. On average, there were 3.4±1.8 (range, 0-8) high-risk ECG parameters per subject among the 11.7±4.5 (range, 4-15) parameters that could be assessed. Thus, 34% of all assessable parameters were abnormal. In conclusion, a significant proportion of ECG parameters cannot be assessed in patients with ischemic cardiomyopathy, but high-risk results are ubiquitous. The influence of these issues will be clarified when the results of the PAREPET study are available to actually determine the predictive value of these parameters on cause-specific mortality in a high-risk cohort.

“…Thus, it plays an important role to assess the short-term and long-term prognostic outcomes, as well as preventing adverse events and improving prognosis for patients (Das et al, 2006;. More researchers are now focusing on clinical application of fQRS (Carey et al, 2010). Currently, there are many theories on the mechanism of fQRS (Flowers et al, 1969;Frustaci et al, 2005;Zhang et al, 2011).…”

This study is aimed to investigate the clinical significance and the short-term prognostic value of fragmented QRS (fQRS) for patients with acute myocardial infarction (AMI). Three hundred patients with AMI were tested with retrospective analysis on the patients' clinical information, hospitalized treatment, fQRS onset time, location of lesions, and other relevant data, in order to assess the relationship between the presence of fQRS and its prognosis. The rates of malignant cardiac arrhythmia, left ventricular systolic dysfunction (LVSD), and mortality in the positive fQRS group were 13.6%, 29.2%, and 23.7%, respectively, with all showing a p value <0.05. For the ST segment elevation myocardial infarction (STEMI) subgroup, all the rates showed significant differences with a p value <0.01, while for the non-STEMI (NSTEMI) subgroup showed no significant differences. In patients with a positive fQRS, there were no differences in malignant cardiac arrhythmia between patients with and without percutaneous coronary intervention (PCI) (p>0.05). As for the LVSD and mortality, the p values between patients with and without PCI were 0.031 and 0.000, respectively, suggesting statistical significance. The results imply that AMI patients with positive fQRS especially for the patients with STEMI had higher rates of malignant cardiac arrhythmia, LVSD, and mortality than the non-fQRS group. Patients of AMI with positive fQRS, who underwent early revascularization, could lower the incidence of the cardiovascular event. In addition, the presence of fQRS could be used as an indication of early intervention treatment for patients.
