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. TIMI 2 flow (partial reperfusion) is delayed or sluggish antegrade flow with complete filling of the distal territory.Background: 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.TIMI 1 flow (penetration without perfusion) is faint antegrade coronary flow beyond the occlusion, with incomplete filling of the distal coronary bed.TIMI 0 flow (no perfusion) refers to the absence of any antegrade flow beyond a coronary occlusion.
'TIMI Grade Flow' is a scoring system from 0-3 referring to levels of coronary blood flow assessed during percutaneous coronary angioplasty: TIMI risk can be calculated on the TIMI website under "Clinical Calculators." 'TIMI risk' estimates mortality following acute coronary syndromes. % risk at 14 days of: all-cause mortality, new or recurrent MI, or severe recurrent ischemia requiring urgent revascularization. ST changes of at least 0.5mm on admission EKG At least 2 angina episodes within the last 24hrs Or female first-degree relative or mother less than 65). (CAD in male first-degree relative, or father less than 55, Such as: Hypertension -> 140/90 or on antihypertensives, Known Coronary Artery Disease (CAD) (coronary stenosis >= 50%) Aspirin use in the last 7 days (patient experiences chest pain despite ASA use in past 7days) TIMI Score Calculation (1 point for each): It is used to categorize a patient's risk of death and ischemic events and provides a basis for therapeutic decision making. The TIMI Risk Score is used in patients with U nstable Angina / Non-ST Elevation Myocardial Infarction. It has conducted numerous practice-changing clinical trials in patients with cardiovascular disease or risk factors for cardiovascular disease TIMI stands for ' Thrombolysis In Myocardial Infarction' and is the name of an Academic Research Organization (ARO) which was founded by Dr.
