In-hospital prognosis in non-ST-segment elevation acute coronary syndrome derived using a new risk score based on electrocardiographic parameters obtained at admission.

Several electrocardiographic variables are of prognostic value in non-ST-segment elevation acute coronary syndrome (NSTEACS). From observations in 427 patients, we developed a new risk score (the ECG-RS) based on admission ECG findings that can be used to determine the likelihood of death or recurrent ischemia during hospitalization, which occurred in 36% of patients. Logistic regression analysis, which considered seven electrocardiographic variables and variables from the Thrombolysis in Myocardial Infarction (TIMI) risk score, identified the following significant predictors: corrected QT interval (QTc) > or =450 ms (odds ratio 4.

Relationship between the QTc interval at hospital admission and the severity of the underlying ischaemia in low and intermediate risk people studied for acute chest pain.

Background: The corrected QT interval (QTc) is prolonged in the setting of acute coronary artery disease. However, very little data are available concerning the relationship between the QTc obtained soon after an episode of acute chest pain (ACHP) and the magnitude and severity of the myocardial ischaemia objectified in subsequent stress tests (STS).

Methods: This was a prospective and observational study in which we investigated the relationship between the QTc determined on the hospital admission electrocardiogram (AQTc) using Bazett's formula and the results of the STS performed subsequently in 206 patients consecutively admitted to the Emergency Department for ACHP without persistent ST-elevation.

Short- and long-term prognostic value of the corrected QT interval in the non-ST-elevation acute coronary syndrome.

Background And Purpose: Myocardial ischemia prolongs the QTc interval. Very little data exists about its prognostic implications in the non-ST-elevation acute coronary syndromes (NST-ACS).

Methods: This is and observational and prospective study in which we evaluated the prognostic implications of the QTc obtained at admission (AQTc) in the short- and long-term of the NST-ACS.

[Recurrent coronary thrombosis, factor V Leiden, primary antiphospholipid syndrome and HIV].

We describe a 54-year-old man who was HIV-positive, admitted for cardiogenic shock complications inferior myocardial infarction. He was treated with primary percutaneous transluminal angioplasty (PCTA) and stent deployment in mid right coronary artery. After a few days thrombotic occlusion of the stent occurred, and the problem recurred during implantation of a new stent in the course of a second PTCA.
