The goal of this is observational study is to compare about MACE events and predisposing factors related to MACE events in elderly patients with high-risk non-ST acute coronary syndromes receiving early versus late invasive treatment . This study will anwser two questions.
Question 1: What will factors associate with implementing a late invasive strategy in elderly patients with high-risk non-ST-segment elevation acute coronary syndrome ? Question 2: Is a meaningful difference about mortality and complication rates as re-myocardial infarction, heart failure, re-hospitalization, stroke after 12 months between two groups of patients undergoing early invasive and late invasive strategies in elderly patients with in high-risk non-ST-segment elevation acute coronary syndrome?
