Clinical characteristics and outcomes of patients with intracerebral hemorrhage after acute myocardial infarction

Data regarding patients with intracranial hemorrhage (ICH) following acute myocardial infarction (AMI) is scarce. This study aims to investigate the incidence, clinical characteristics, prevention, treatment, and prognosis of ICH in patients with AMI. Among 5257 patients with AMI, 14 cases (0.27%) experienced ICH following AMI, including 11 males and three females. In-hospital mortality occurred in eight patients (57.1%), all of whom experienced sudden loss of consciousness. Six patients (42.6%) were classified as high or very high risk according to CRUSADE score, and seven patients (50.0%) were classified as high risk according to Academic Research Consortium for High Bleeding Risk (ARC-HBR). The CRUSADE and ARC-HBR scores can complement each other in risk assessment. All in-hospital deaths occurred within four days of ICH onset; The volume of ICH in patients who died in the hospital was significantly higher than in those who survived and were discharged, with 30 ml possibly serving as a threshold.The incidence of ICH following myocardial infarction is low; however, the mortality rate is extremely high, presenting considerable challenges for clinical treatment. Prevention, early detection, and prompt symptomatic management are essential for improving patient outcomes.

Automated summary

This study investigates the incidence, clinical characteristics, prevention, treatment, and prognosis of intracranial hemorrhage (ICH) in patients with acute myocardial infarction (AMI). In-hospital mortality rate is extremely high, with sudden loss of consciousness associated with all deaths. The CRUSADE and ARC-HBR scores can complement each other in risk assessment. The volume of ICH is significantly higher in patients who die in the hospital compared to those who survive.
