Predictive value of red cell distribution width in intrahospital mortality and postintervention thrombolysis in myocardial infarction flow in patients with acute anterior myocardial infarction.
Recent studies have reported a strong independent association between increased red cell distribution width (RDW) and the risk of adverse outcomes in patients with heart failure, stable coronary disease, and acute coronary syndromes. However, in this study we aimed to determine the impact of an elevated RDW level on the postinterventional thrombolysis in myocardial infarction (TIMI) flow and intrahospital mortality in patients with acute anterior myocardial infarction (AMI). ⋯ A high admission RDW level in patients with acute AMI undergoing a primary percutaneous coronary intervention was associated with an increased risk for intrahospital cardiovascular mortality, but was not associated with worse postinterventional TIMI flow.

SYNTAX score: an independent predictor of long-term cardiac mortality in patients with acute ST-elevation myocardial infarction.
This observational study aimed to determine whether the SYNergy between percutaneous coronary intervention (PCI) with TAXUS drug-eluting stent and the cardiac surgery (SYNTAX) score can act as an independent predictor for cardiac death on long-term follow-up in patients with acute ST-elevation myocardial infarction (STEMI). ⋯ The SYNTAX score is a strong independent predictor of cardiac death in intermediate-risk to high-risk patients with acute STEMI.

Gated-SPECT myocardial perfusion imaging and coronary calcium score for evaluation of patients with acute chest pain and a normal or nondiagnostic electrocardiogram.
To assess the ability of rest myocardial perfusion imaging (MPI) to rule out an acute coronary syndrome (ACS) in emergency department patients, as well as to investigate whether there exists a concordance between MPI and coronary calcium. ⋯ Patients presenting with acute chest pain and a low-to-intermediate likelihood of coronary artery disease with a normal rest MPI have a very low probability of cardiac events during the first year. Coronary calcium score was not helpful in risk-stratifying these patients.
