Three-dimensional speckle tracking imaging-based evaluation of influences of systematic cardiac rehabilitation nursing on cardiac function after interventional treatment of acute myocardial infarction

Acute myocardial infarction (AMI) is a life-threatening condition that requires effective post-intervention care. This study aimed to assess the impact of systematic cardiac rehabilitation nursing on heart function and mental health in patients following AMI intervention. A total of 200 AMI patients were assigned to the control group (routine nursing) and the observation group (systematic cardiac rehabilitation nursing). Heart function was evaluated before and after the intervention using three-dimensional speckle tracking imaging (3D-STI). Additionally, the effects of different nursing approaches on AMI patients undergoing intervention were analyzed. Systematic cardiac rehabilitation nursing led to significant improvements in clinical indicators and notable lipid-lowering effects. Compared to routine nursing, systematic cardiac rehabilitation nursing markedly ( p < 0.05) reduced the SAS score, improved the SF-36 score, and led to a 15.2 % reduction in LDL levels. Furthermore, 3D-STI showed a notable ( p < 0.05) improvement in radial strain and a reduction in area strain in observation group. Systematic cardiac rehabilitation nursing markedly improved heart function and mental health in patients following AMI, as demonstrated by 3D-STI, though further multicenter studies are needed to confirm generalizability.
