![]() Our hypothesis was that the RISK-PCI score was as accurate as the GRACE and TIMI scores in predicting a composite MACE in patients with UA/NSTEMI. Although the GRACE score has already been established as the score of choice for the risk estimation ( 13), RISK-PCI also seems to be reliable considering that it includes clinical, laboratory, and diagnostic parameters. RISK-PCI score has not been tested in patients with UA/NSTEMI. The definitive value of all the scores is influenced by various clinical factors, such as score variables, period of the score evaluation, patient population, and analyzed adverse cardiovascular outcomes. Predicting 30-day major adverse cardiovascular events after primary percutaneous coronary intervention (RISK-PCI score) was developed to predict 30-day MACE, such as non-fatal REMI, death, and cerebrovascular insult, in patients with STEMI after percutaneous coronary intervention (PCI) ( 12). Several international reports compared the GRACE score with the TIMI score, showing that the GRACE score was a better predictor of clinical outcome than the TIMI score ( 10, 11). As it was based on a wider sample of unselected population ( 9), it is more reliable for the routine clinical use. Unlike TIMI, the GRACE score was derived from the Global Registry of Acute Coronary Syndrome data. Global registry for acute coronary events (GRACE) score demonstrated its superiority in the assessment of 6-months mortality risk ( 7, 8). However, the TIMI score was based on clinical studies including selected populations of patients with low comorbidity rates and it does not always reflect the reality in clinical practice. Several studies confirmed the efficacy of this index in the prognosis of mortality within 30-day period, although some attenuation was shown for patients older than 65 years ( 3- 6). Also, the TIMI score evaluates 14-day adverse events in patients with unstable angina (UA)/non-ST-segment elevation myocardial infarction (NSTEMI). Thrombolysis in myocardial infarction (TIMI) is a simple bedside score that predicts 30-day mortality in patients with ST-elevation myocardial infarction (STEMI). ![]() ![]() Risk stratification is a useful tool for planning early treatment, discharge, and rehabilitation of ASC patients, performing research after ACS, and expediting the definitive decision about further treatment ( 1, 2).ĭifferent scores are in use for the estimation of ACS outcome. Patients with TIMI score > 4 were more likely to have significant three vessel CAD and LMS versus those with TIMI risk score 4 should be referred for early invasive coronary evaluation to derive clinical benefit.Variations in clinical appearance and outcome in patients with acute coronary syndrome (ACS) require a reliable method of risk assessment for further major adverse cardiac events (MACE) during the ACS treatment. The extent of CAD was evaluated on angiography and significant CAD was defined as ≥ 70% stenosis in any one of the three major epicardial vessels and ≥50% in LMS.Results : Among 100 patients with UA/NSTEMI, 82% of patients have one or more risk factors and only 18%of patients lacked any of 4 conventional risk factors.Smoking is the most common risk factor in male patients while diabetes mellitus and dyslipidemia are common among female patients, and all these results are statistically significant.There were 64 % patients with TIMI score 4 (high TIMI risk score). ![]() The TIMI risk score was stratified on seven standard variables. Extensive epidemiological research has established cigarette smoking, diabetes, hyperlipidemia, and hypertension as independent risk factors for CADObjective: To determine the prevalence of the 4 conventional risk factors(cigarette smoking, diabetes, hyperlipidemia, and hypertension) among patients with CAD and to determine the correlation of Thrombolysis in Myocardial Infarction (TIMI) risk score with the extent of coronary artery disease (CAD) in patients with unstable angina /non ST elevation myocardial infarction (UA/NSTEMI).Methods: We conducted a descriptive study among 100 patients admitted with UA/NSTEMI to three major cardiac centers in Iraq: Iraqi Centre for Heart Disease ,Ibn- Al-Bitar Hospital for cardiac surgery and Al -Nasyria Cardiac Centre from January 2010 to January 2o11.Frequency of each conventional risk factors and number of conventional risk factors present among patients with CAD, compared between men and women and by age are estimated at study entry. ![]() Unstable angina, Thrombolysis in Myocardial Infarction score, risk factors Abstractīackground: Appreciation of the crucial role of risk factors in the development of coronary artery disease (CAD) is one of the most significant advances in the understanding of this important disease. ![]()
