Correlation of Timi Risk Score with Gensini Score in patients with NSTEMI.
J Cardiovascular Dis Jan ;15(4):109-12.

Multiple risk scores have been applied in patients who present in cardiac emergencies to risk stratify patients into different groups ranging from low to high risk categories. One common and easily useable risk score is Thrombolysis in Myocardial Infarction (TIMI) Score. The stratification can be used as a clinical tool. This study was performed to see the correlation of angiographic extent of coronary artery disease by assessing GENSINI score with different classes of TIMI risk score in patients presenting with non-ST-elevation myocardial infarction (NSTEMI). MATERIAL AND METHODS: It was a cross-sectional observational survey conducted in Cardiology Department ,(PIC)Punjab Institute of Cardiology, Lahore over a duration of six months from 31st October 2013 to 30th March 2014. Using consecutive sampling, 131 patients with NSTEMI with age between 30 to 70 years of either sex were enrolled. Patients with past history of ischemic heart disease and STEMI were excluded. NSTEMI was labeled as new onset or worsening chest pain, without acute ST elevation MI or having left sided bundle branch block on ECG and elevated cardiac troponin-I >= 0.2ng/ml). Modified GENSINI score on angiography was used to measure the extent of coronary vessels involvement and correlation between angiographic severity of coronary artery disease with TIMI score was calculated. RESULTS:131 patients were included with mean age of 57.73 +- 6.974 ranging from 30 year to 70 years of age. Mean TIMI score was 3.90 +- 1.593 and mean Gensini score was 69.08 +- 11. 9 patients. There were 96 (73.3%) males while remaining 35 (26.7%) were female patients. Correlation between angiographic severity of coronary artery disease with different classes of Thrombolysis in Myocardial Infarction (TIMI) risk score in patients presenting with non-ST- segment elevation myocardial infarction was linear and strongly positive (r=0.774) and showed that TIMI risk score is valid in our population. CONCLUSION: It is concluded that Thrombolysis in Myocardial Infarction (TIMI) risk score can be used as a valid tool for the stratification of patients after non ST-Segment elevation myocardial infarction and is directly correlated with Gensini score.
