Do collaterals to infarct bed in STE-ACS patients undergoing emergent percutaneous coronary revascularization matter? An assessment of a prospective pool for in-hospital course.

Background: Limited data exist on the role of coronary collaterals circulation (CCC) in patients with ST-elevation acute coronary syndrome (STE-ACS). This study aimed to assess CCC and the in-hospital course of patients with CCC undergoing primary percutaneous coronary intervention (pPCI).

Methods: The study included consecutive STE-ACS patients undergoing pPCI.

Prospective Validation Of Heart Score For Suspected Acute Coronary Syndrome Patients.

Background: The HEART score is reported to be a useful tool for the assessment of suspected acute coronary syndrome (ACS) patients, however, data regarding its validity in our population is scarce. Therefore, aim of this study was to evaluate the prognostic utility of the HEART score to predict major adverse cardiac events (MACE) within 6 weeks in patients presenting to emergency department with chest pain.

Methods: This prospective observational study included suspected ACS patients presented with chest pain to the emergency department of a tertiary care cardiac center.

Prognostic value of GRACE score for in-hospital and 6 months outcomes after non-ST elevation acute coronary syndrome.

Background: The aim of this study was to determine the predictive value of the Global Registry of Acute Coronary Events (GRACE) score for predicting in-hospital and 6 months mortality after non-ST elevation acute coronary syndrome (NSTE-ACS).

Results: In this observational study, 300 patients with NSTE-ACS of age more than 30 years were included; 16 patients died during the hospital stay (5.3%).

Validity of TIMI Score for Predicting 14-Day Mortality of Non-ST Elevation Myocardial Infarction Patients.

Background Accurate management of non-ST elevation myocardial infarction (NSTEMI) patients can be achieved by stratifying risks as early as possible on hospital admission. Previously, the Thrombolysis in Myocardial Infarction (TIMI) risk score has been validated and used on patients presenting with NSTEMI or unstable angina (UA) in developed countries. The aim of this study was to assess the validity of the TIMI risk score in patients presenting with NSTEMI in Pakistan.
