Cardiovascular disease is the leading cause of death globally. A critical form of cardiovascular disease is Acute Coronary Syndrome (ACS), which includes heart attack and unstable angina that may lead into heart attack. GRACE risk score was developed by a multivariable logistic regression model in a heart study using 11.389 acute coronary syndrome (ACS) patients. It is important to determine factors that are predictive of death across the entire spectrum of acute coronary syndrome (ACS), hence the risk stratification by GRACE score become a routine part in acute coronary syndrome (ACS) investigation for better risk-management and preventing death. Disclaimer: all calculations must be re-checked and should not be used alone to guide patient care, nor should they substitute for clinical judgment. Calculations in this "GRACE Risk Score: Heart Attack Management" app might be different with your local practice. Consult to expert doctor whenever necessary.
