Owing to small numbers TIMI score groups 6 and 7 were amalgamated in keeping with the original paper. The first ECG was used to calculate scores. A front door score was also calculated by removing the cardiac marker element from the TIMI score. The elements are age ⩾ 65 years, three or more risk factors for coronary artery disease, known coronary artery stenosis, use of aspirin for the past seven days or more, raised cardiac markers, ⩾ 0.5 mm deviation of the ST segment on ECG, and two or more episodes of angina in the past 24 h. The TIMI score consists of seven elements, each scoring one point. TIMI scores were then calculated for each patient. Patients were followed up to hospital discharge or 30 days after enrolment. Several variables were determined and recorded on a structured form. Exclusion criteria were age less than 20 years and the initial assessing clinician's judgement that chest pain was of a non‐cardiac nature. One thousand consecutive patients presenting with potentially cardiac chest pain were enrolled. 2000 284 (7): 835-42.The study took place in a single urban teaching hospital emergency department with 85 000 adult attendances yearly. The TIMI risk score for unstable angina/non-ST elevation MI: A method for prognostication and therapeutic decision making. TIMI risk score accurately risk stratifies patients with undifferentiated chest pain presenting to an emergency department. Application of current guidelines to the management of unstable angina and non-ST-elevation myocardial infarction. TIMI risk score for ST-elevation myocardial infarction: A convenient, bedside, clinical score for risk assessment at presentation: An intravenous nPA for treatment of infarcting myocardium early II trial substudy. Morrow DA, Antman EM, Charlesworth A et-al. female first-degree relative or mother younger than 65 yearsĪ percentage risk at 14 days of all-cause mortality, new or recurrent myocardial infarction, or severe recurrent ischemia requiring urgent revascularization.male first-degree relative or father younger than 55 years.family history of premature coronary artery disease.hypertension >140/90 mmHg or on anti-hypertensives.at least 3 risk factors for coronary artery disease, which include:.known coronary artery disease (CAD) (coronary stenosis ≥50%).ST changes of at least 0.5 mm in contiguous leads.at least 2 angina episodes in the last 24 hours.aspirin use within the last 7 days (patient has chest pain despite as required use in past 7 days).It is thought to have potential to improve the management of patients presenting to hospital with undifferentiated chest pain where ischemic heart disease is a potential diagnosis 3. The thrombolysis in myocardial infarction (TIMI) risk score is a prognostic risk stratification system that categorizes the risk of death and ischemic events in patients with unstable angina / non-ST elevation myocardial infarction and provides a basis for therapeutic decision making.
