Severe angina (≥ 2 episodes w/in 24 hrs).Known coronary artery disease (CAD) (stenosis ≥ 50%).TIMI Score Calculation (1 point for each): In patients with UA/NSTEMI, the TIMI risk score is a prognostication scheme that categorizes a patient's risk of death and ischemic events and provides a basis for therapeutic decision making. Among the group's most important works is the TIMI Risk Score, which assesses the risk of death and ischemic events in patients with unstable angina (UA) or non-ST elevation myocardial infarction (NSTEMI). Braunwald held the chairmanship until 2010, when he appointed Marc Sabatine to the position. The TIMI Study Group was founded by physician Eugene Braunwald in 1984. The group has its headquarters in Boston, Massachusetts. The Thrombolysis In Myocardial Infarction ( TIMI) Study Group, is an academic research organization (ARO) affiliated with Brigham and Women's Hospital and Harvard Medical School with a focus in the field of cardiovascular disease.

Patients with a non–ST-elevation acute coronary syndrome who have a high or intermediate TIMI risk score should be treated with an early invasive strategy. However, in this patient with a high pretest probability of CAD, coronary CT angiography would only delay critical therapy. Coronary CT angiography is appropriate, and rest single-photon emission CT may be appropriate. In patients with suspected NSTE-ACS with a normal initial troponin level and inconclusive electrocardiographic findings, further diagnostic studies may be indicated. However, an invasive strategy has been shown to improve the composite clinical endpoint of death, recurrent myocardial infarction, and repeat hospitalization compared with an ischemia-guided approach in patients with NSTE-ACS. Stress testing with adenosine nuclear stress testing or exercise stress electrocardiography could be considered for purposes of risk stratification if this patient declines an early invasive strategy. His score places him at high risk for death and cardiac ischemic events, and despite the absence of elevated cardiac biomarker levels, urgent coronary angiography is warranted. This patient has a TIMI risk score of 5, as indicated by the presence of three traditional risk factors for coronary artery disease, aspirin use within the last week, age older than 65 years, two or more angina episodes in the past 24 hours, and significant ST-segment deviation on electrocardiogram. An early invasive strategy benefits patients with high TIMI risk scores (5-7) and intermediate TIMI risk scores (3-4). Risk stratification tools, such as the TIMI risk score, can be used to determine which patients with NSTE-ACS should be treated with an invasive strategy versus an ischemia-guided approach. Patients with a non–ST-elevation acute coronary syndrome (NSTE-ACS) should undergo risk stratification before invasive treatment because the link between revascularization and clinical outcomes is less clear in these patients than in patients with ST-elevation myocardial infarction (STEMI). This patient should undergo urgent angiography. Treat a patient with a non–ST-elevation acute coronary syndrome with an early invasive strategy. D: Urgent angiography Educational Objective ![]()
