In a nutshell

This study aimed to investigate if there was a link between gender and readmission rates after acute myocardial infarction.

This study concluded that women, and in particular younger women, had a higher risk of readmission after acute myocardial infarction. 

Some background

Acute myocardial infarction (AMI) is more commonly known as a heart attack. It occurs when the arteries that deliver blood to the heart become blocked with plaque. The plaque build-up leads to blockages that stop blood flow. Readmission to hospital after AMI is a common occurrence. Patients who have experienced an AMI are more likely to experience recurrent AMI and other heart related events.

It was not known if men or women are more likely to be readmitted to hospital after being diagnosed with AMI and discharged from hospital.  

Methods & findings

This study involved 214,824 patients who were diagnosed and discharged from hospital with AMI. 44% of these patients were in the 18-64 age group (younger). 56% of patients were in the 65 and older age group (older). Patients were followed for 30 days after being discharged from hospital.

The readmission rate for the younger group was 14% for women and 10% for men. The readmission rate for the older group was 18% for women and 16% for men.

The risk of 30-day readmission was higher for women with AMI compared to men with AMI. The risk was 21% higher in younger women (aged 18-44) compared to men. In older women, the risk was 13% higher.

The most common reasons for readmission were recurrent AMI, ischemic heart disease and heart failure. 

The bottom line

This study concluded that women, and in particular younger women, are at higher risk of short-term readmission after AMI than men. 

The fine print

A larger study that better represents the general population needs to be carried out. 

What’s next?

Consult your physician about the risk of readmission after AMI.
