Generally, even if you have had a cerebral hemorrhage before, you can undergo cardiac stenting after the symptoms of the cerebral hemorrhage are stabilized. In general, if the coronary artery branches such as anterior descending branch and circumflex branch are examined and the stenosis reaches more than 75%, it is an indication for cardiac stent implantation. There are also absolute or relative contraindications to cardiac stent implantation, such as current severe infections and shock; electrolyte disorders such as potassium; active bleeding; and hyperthyroidism. A history of cerebral hemorrhage is not an absolute contraindication to cardiac implantation, and after stabilization with treatment, such as after six months, cardiac stenting can be performed after evaluation by a medical professional and is relatively safe at this time.
