BACKGROUND The occurrence of variations in the spectrum of cardiovascular disease between different regions of the world and ethnic groups have been the subject of great interest. This study report the 24-h variation of myocardial infarction (MI) occurrence in patients recruited from CCU located in Argentina and Uruguay. METHOD A cohort of 1063 patients admitted to the CCU within 24 h of the ...

BackgroundThe standard 12-lead electrocardiogram (ECG) has relatively low sensitivity for the diagnosis of posterior wall acute myocardial infarction (AMI). The prevalence of posterior wall myocardial infarction (MI) has been studied in a few studies. We evaluated ST-segment elevation (STE) prevalence in posterior leads in patients with acute coronary syndrome (ACS) in order to determine the pr...

56 years old lady with recent history of Inferior MI, and also found to have Spontaneous coronary artery dissection RCA on angiography. She has hypertension is an ex-smoker. MRI head was previously done showing evidence small vessel disease 2 lacunar infarcts. Underlying vasculitis were suspected, therefore specialist suggested further investigations exclude extra arteriopathy, which led the CT...

Pulsed field ablation (PFA) is a nonthermal energy modality that largely spares collateral structures like the esophagus and phrenic nerve. However, recent study indicates subclinical coronary artery vasospasm common during PFA of cavo-tricuspid isthmus. There also case report left circumflex (LCx) at mitral isthmus (MI). To determine frequency LCx on lateral MI compare to RFA. In prospective, ...

Although numerous behavioural studies provide evidence that there exist wide differences within individual motor imagery (MI) abilities, little is known with regards to the functional neuroanatomical networks that dissociate someone with good versus poor MI capacities. For the first time, we thus compared, through functional magnetic resonance imaging (fMRI), the pattern of cerebral activations...

was made to differentiate these records from electrocardiograms showing a similar pattern as a result of anterior myocardial infarction (MI). Orthogonal ECGs (Frank system) obtained from 103 patients with LVH were compared to ECGs obtained from 327 patients with MI. The ECGs were selected on the basis of absence of Q waves in lead Z which in the conventional ECG corresponds to absence of the R ...

most often in the posterior of the mandible of patients who need implants, the inferior alveolar nerve (ian) is too high to insert the implants, and the surgeons have to reposition ian. in conventional techniques (to make the windows in the buccal aspect of the mandible) removal of the corticocancellous bone may cause weakness of the mandible. here we present a new technique in which the bone i...

OBJECTIVES For over 50 years, Q-wave myocardial infarction (MI) location has been based on pathologic ECG studies. Although contrast-enhanced magnetic resonance (CE-CMR) is currently the "gold standard" technique for location and quantification of necrotic areas, we found no large study in the literature devoted to establish which ECG patterns corresponds to different MI location detected by CE...

The effective connectivity networks among overlapped core regions recruited by motor execution (ME) and motor imagery (MI) were explored by means of conditional Granger causality and graph-theoretic method, based on functional magnetic resonance imaging (fMRI) data. Our results demonstrated more circuits of effective connectivity among the selected seed regions during right-hand performance tha...
