Psychiatric morbidity as a risk factor for hospital readmission for acute myocardial infarction: an 8-year follow-up study in Spain.
OBJECTIVE
Most previous studies assess the effect of depression and other psychiatric variables as risk factors for acute myocardial infarction; however, studies that assess the effect of psychiatric disorders as a whole are scarce, compared with other non-psychiatric factors. The aim of this study is to assess the importance of psychiatric morbidity, compared with other risk factors, in hospital readmission for acute myocardial infarction.


METHODS
This is a 8-year follow-up study in which the Hospital Discharge Administrative Database was used.


RESULTS
From the total sample (11,062 patients), 590 patients (4.88%) were diagnosed with some mental disorder. Psychiatric disorders were more common in women than in men with myocardial infarction (4.76 % and 6.20%, respectively, p-value = 0.002). For those who have had recurrence of stroke, mental disease influences in the consecutive readmission for AMI with the same severity as did tobacco, diabetes, or obesity.


CONCLUSIONS
The main finding of this study is the enormous impact of psychiatric disorders on readmissions for AMI, comparable to diabetes, obesity, cerebral vascular disease, and hypertension. Interestingly, the efforts made to treat and prevent psychiatric disorders in AMI patients are clearly lower than those health authorities make with respect to classic risk factors.
