Heart attack stenting after the right arm is not normal, there may be a simultaneous occurrence of cerebrovascular disease, the need for timely hospitalization, alert to the possibility of surgical complications. Myocardial infarction patients treatment stent is the main treatment, the stent is mainly placed in the coronary artery, and will not cause significant damage to the cerebral blood vessels, under normal circumstances should not appear right arm no strength. The right arm is not strong after stenting for myocardial infarction, and there are three situations to consider: 1. In the process of stent implantation, the surgical instruments may lead to the dislodgement of intra-arterial plaque, and there is a risk of cerebral embolism, which can lead to the loss of strength in the right arm. 2. After myocardial infarction, the person is in a state of stress, and there is a risk of concurrent cerebral infarction, which can lead to weakness in the right arm. 3. The process of entering the guidewire through the right radial artery may lead to vascular injury in the right upper limb, resulting in bleeding in the right forearm, and the compression of the nerve by the hematoma may lead to weakness of the right upper limb. The right arm weakness after stenting for heart attack should be investigated by cranial CT, and the right upper limb should be examined at the same time to find out the specific cause. Specific diagnosis and treatment need to follow the doctor’s advice.
