Introduction: Higher levels of troponins >10 folds of upper normal limits (UNL) are considered as high-risk

patients on coronary angiography sufferers having high levels of troponin-I (>10 folds upper limit normal level) had

extra three-vessel coronary artery disease involvement.

Objectives: To determine the frequency of degree of cardiovascular disease with Troponin-I level >10 folds ULN

in NSTEMI patients at tertiary care hospital.

Methodology: It is a cross-sectional study comprising of a total 800 patients recruited from the Department of

Cardiology, National Institute of Coronary Disease, Karachi Pakistan based on Exclusion/Inclusion criteria.

Results: There are 678 male as well as 122 female patients. The mean troponin-I level was 15.00±6.82 ng/ml.

Single vessel disease found in 25.25% cases, two vessel diseases were observed in 37.75% cases, and three

vessel diseases were observed in 20% cases. 83% were found with extent of CAD findings on angiography.

There have been 678 male and also 122 female patients. The mean troponin-I level was 15.00±6.82 ng/ml. Single

vessel disease found in 25.25% cases, two vessel diseases were observed in 37.75% cases, and three vessel

diseases were observed in 20% cases. 83% were found with extent of CAD findings on angiography.

Conclusion: The higher troponin level found significantly associated with extent of CAD and three vessel

disease. To understand the cardiovascular troponin condition of the sufferer as soon as feasible is crucial.
