This clinical trial aims to compare conventional radial access versus distal radial access in patients with STEMI undergoing PCI. The main question it aims to answer is: • Mayor adverse cardiac events (MACE) at 30 days in STEMI patients treated by PCI are not inferior when comparing the distal radial approach versus the conventional radial approach ? Participants will: * sign the informed consent to enroll in the clinical trial. * will agree to be treated by PCI * will be randomized 1:1 to perform PCI by conventional radial or distal radial approach. If there is a comparison group: Researchers will compare conventional radial access vs distal radial access to see if the distal approach is not inferior compared to the conventional radial access in order to offer less or equal MACE and a similar rate of a successful procedure.
