Correlation analysis of illness severity and depression degree in patients with acute myocardial infarction.

Objective To investigate the correlation between depression status, severity of illness and severity of depression in patients with acute myocardial infarction (AMI), and to provide reference for drawing up intervention measures. Methods A total of 122 patients with AMI were given Zung self-rating depression scale to assess the degree of depression, the global registry of acute coronary events (GRACE) risk score to assess the severity of illness after AMI attack 5 to 7 days. Results Zung self-rating depression scale score of these patients with AMI was higher than the national norm (P<0.01). 44 cases had depression syndrome, accounting for 36.0%; the GRACE risk score and the degree of depression were positively correlated, but the correlation was not significant (r=0.012) and therefore there was not statistical significance (P=0.892). Conclusions The incidence rate of depression after the occurrence of acute myocardial infarction was relatively higher, and there was no significant correlation between the severity of depression and the severity of the disease. Nursing staff should pay attention to this symptom, timely assess and properly treat the impact of the severity of the disease on the degree of depression, and then take targeted care measures to ease the patients′ poor psychological state.
