Brief Summary The Purpose of the Study : The purpose of this study is to find a safe and reliable "one-stop" solution for treating heart attack patients who have multiple blocked arteries. Currently, doctors face a dilemma: Testing these other blockages during the heart attack procedure is often unreliable. The most accurate method requires asking the patient to return 30 days later for a second invasive procedure, which is a significant burden. The Study's Hypothesis : We are testing a new tool called UFR, which uses ultrasound images to measure blockages. Our hypothesis (or "educated guess") is that this new UFR tool is not affected by the body's stress during a heart attack and can provide a true, reliable measurement right away. The Question the Study is Trying to Answer ： The main question this study is trying to answer is: Can the new "one-stop" UFR tool, used during the initial heart attack procedure, accurately predict which blockages are truly serious... thereby eliminating the need for patients to return for a second procedure 30 days later? Researchers will also follow 200 patients for one year, using advanced scans (like UFR, standard tests, and MRI), to better understand how the heart and arteries heal and change over time.
