Abstract
Background: Coronary artery disease and acute coronary syndrome (ACS) are the major causes of death, worldwide. Risk assessment for
patients with ACS is necessary to minimize morbidity and mortality. The global registry of acute coronary events risk score (GRS), the in
thrombolysis myocardial infarction (TIMI) risk score (TRS), and the TIMI risk index (TRI) have been used for patients with ACS to evaluate
their risk. We showed at our study the value of pre‑admission TRI, TRS, and GRS in occurrence prediction of no‑reflow (NRF) Phenomenon
after primary PCI for ST‑elevation myocardial infarction (STEMI) patients; and its impact on the in‑hospital outcome for those patients. Patients
and Methods: Our study included 319 patients presented with STEMI and managed by primary PCI. For all patients, we recorded a detailed
history, clinical examination as well as Killip class, electrocardiogram, and echocardiography. TRI as well, TRS, and GRS were calculated for
all patients. We observed all patients during their PCI at the catheterization room to monitor the result of the intervention. NRF was defined as
TIMI flow grade less than III or TIMI flow Grade III with myocardial blush grade less than or equal to II. Then, we followed the patients during
their hospitalization period to record any associated complications and mortality. Results: We found NRF patients older than reflow patients,
thus regarding age. They were more males. Killip Class III‑IV was found to be more common in NRF patients. TRI as well, TRS and GRS
showed higher values among the NRF patients. As well, in‑hospital major adverse cardiac events (MACEs) and mortality were more common
in NRF patients. Conclusion: We found that the high TRI values were related to the occurrence of NRF, in hospital MACE, and mortality.
