A new electrocardiographic algorithm to locate the occlusion in left anterior descending coronary artery.
Early prediction of proximal left anterior descending coronary artery (LAD) occlusion is essential from a clinical point of view ⋯ This sequential ECG algorithm based on ST-segment deviations in different leads allowed us to predict the location of occlusion in LAD with good accuracy. Cases with proximal LAD occlusion present the most markers of poor prognosis. We recommend the use of the algorithm in everyday clinical practice.

Most of my time these days (at least 26 weeks out of every year) is spent on an inpatient cardiology service. Patients are general cardiology patients, mostly admitted from our emergency department (ED). Approximately half of these patients have a principle diagnosis of acute chest pain.

Comparative StudyQuartiles of peak troponin are associated with long-term risk of death in type 1 and STEMI, but not in type 2 or NSTEMI patients.
The prognostic value of peak cardiac troponin (cTn) in different types of acute myocardial infarction (AMI) under the universal clinical classification is unknown. ⋯ Overall, peak cTn predicts the risk of MACE and death but not the risk of AMI. While in Type 1 and STEMI patients, QPTL are associated with risk of MACE and death, no association exists in type 2 or NSTEMI patients.

Neutrophil count on admission predicts major in-hospital events in patients with a non-ST-segment elevation acute coronary syndrome.
Inflammation plays a key role in the pathogenesis of acute coronary syndromes (ACS). In this context we assessed neutrophil count as a predictor of major in-hospital events in patients admitted for a non-ST-segment elevation (NSTE) ACS. ⋯ In patients with a NSTE ACS of moderate or high risk, neutrophil count on admission may identify those who are at risk of having an adverse in-hospital outcome.
