Forty-eight hours after infarction, intervention is still relevant to improve myocardial ischemia and hemodynamic instability and improve prognosis.
In acute myocardial infarction, percutaneous coronary intervention is usually required within 12 hours to improve myocardial perfusion.
For those who fail to undergo urgent intervention within 12 hours, percutaneous coronary intervention can be performed even 48 hours after the onset of infarction if conservative treatment fails or if there are persistent signs of myocardial ischemia, such as persistent hemodynamic instability and fatal arrhythmias.
Timely intervention is beneficial in improving myocardial ischemia and improving prognosis. Therefore, it is recommended to go to the hospital in case of pain in the anterior region of the heart, dyspnea, a sense of dying, or constriction of the throat. The specific situation varies from person to person, and the treatment is in accordance with the doctor’s prescription.
