Abstract
Introduction
- CVD is responsible for about 30% of all deaths worldwide each year.[9] Nearly, 80% of these deaths occur in developing countries. Indeed, CVD is the leading cause of mortality in almost every region of the world.
- The electrocardiogram (ECG) remains a crucial tool in the identification and management of AMI. Acute risk stratification in AMI is still based on simple clinical parameters; laboratory markers and 12-lead ECG.[4]
- The ECG has been a preliminary screening and one of the most useful diagnostic investigations in AMI.[5]
- Coronary angiography is currently the gold standard to evaluate AMI. It defines the coronary anatomy and determines the extent of epicardial coronary artery and coronary artery bypass graft disease.
- Various ECG presentations in relation with their angiographic finding will be investigated under this study. If correlation between ECG features and angiographic findings is found, a faster and less invasive method can be used to identify diseased vessel, therefore timely intervention can be implemented to lower its mortality rate.
- A detailed analysis of patterns of ST-segment elevation may influence decisions regarding the perfusion therapy. The early and accurate identification of the infarct‑related artery can help predict the area of myocardium at risk and guide decisions regarding the urgency of revascularization.[1]
