BACKGROUND No information is currently available on the prognostic significance of the number of leads with fragmented QRS (fQRS). The objective of the study was to clarify the prognostic significance of the number of leads with fQRS in prior myocardial infarction (MI). METHODS AND RESULTS We retrospectively examined 170 patients with prior MI. The(More)
The investigators prospectively examined 625 consecutive patients who underwent coronary multislice computed tomography (MSCT) for suspected coronary artery disease (CAD) and evaluated the presence or absence of cancers and other noncardiac abnormalities on the original transverse sectional images of MSCT. Eight patients with known cancers were excluded(More)
The aim of the present study was to clarify the prognostic significance of upright T waves (amplitude > 0 mV) in lead aVR in patients with a prior myocardial infarction (MI). We retrospectively examined 167 patients with a prior MI. The primary end point was cardiac death or hospitalization for heart failure. During a follow-up period of 6.5 ± 2.8 years, 34(More)
BACKGROUND No information is available on the clinical significance of a positive T wave in lead aVR in myocardial infarction (MI). Accordingly, in the present study, we sought to clarify the associations of the positive T wave in lead aVR with hemodynamic, coronary angiographic, and left ventriculographic findings in anterior wall old MI. METHODS We(More)
The aim of this study was to clarify the prognostic significance of P-wave terminal force in lead V1 (PTFV1) in patients with prior myocardial infarction (MI). We retrospectively examined 185 patients with prior MI. The primary end point was cardiac death or hospitalization for heart failure. Abnormal PTFV1 was defined as PTFV1 ≥ 40 mm × ms. During a(More)
BACKGROUND Previous studies have demonstrated that an elevated neutrophil count on admission is associated with a higher risk of adverse events after acute myocardial infarction (AMI). However, the significance of the neutrophil count after reperfusion therapy has not been elucidated. METHODS AND RESULTS The association of the neutrophil count on(More)
Several studies have examined the ability of electrocardiography to differentiate between takotsubo cardiomyopathy (TC) and anterior wall acute ST-segment elevation myocardial infarction (AA-STEMI). In those studies, the magnitude of ST-segment elevation was not measured at the J point. The American Heart Association, American College of Cardiology(More)
BACKGROUND The efficacy and safety of sarpogrelate, a selective 5-hydroxytryptamine receptor subtype 2A antagonist, have not yet been established in bare metal coronary stenting. Accordingly, we sought to clarify whether treatment with sarpogrelate is clinically useful in bare metal coronary stenting. METHODS A total of 450 patients who underwent(More)
