Non STEMI

Coronary computed tomography angiography (CCTA) is a widely accepted initial diagnostic test for individuals suspected of having chronic coronary syndromes. However, there is limited evidence supporting its use in the acute setting. So far, no large-scale randomized trial has examined the performance of CCTA as an alternative to invasive coronary angiography (ICA) in individuals with non-ST-segment elevation myocardial infarction (NSTEACS). If CCTA were to replace ICA as a routine procedure for individuals with NSTEACS, it could reduce the risk of complications related to ICA, improve patient comfort, expedite decision-making, and reduce healthcare expenses and interhospital transfers.

1. Evaluation of serum level of remnant cholesterol and monocyte/HDL ratio as predictors of severity of coronary artery disease in patients with acute coronary syndrome. 2. Evaluate predictive value of remnant cholesterol serum level and monocyte/HDL ratio to detect in-hospital worse clinical outcomes and 45 days major adverse cardiac events (MACE) after acute coronary syndrome.
