Heart attack patients treated at hospitals with low care scores are at greater risk for another heart attack and/or death due to cardiovascular causes, Rutgers researchers found.

Their study, published in the American Journal of Cardiology, compared care scores in the New Jersey Hospital Performance Reports with one-month and one-year rates of readmission for heart attack or death due to cardiovascular causes.

Researchers reviewed the electronic medical records of more than 160,000 patients at 80 New Jersey acute care hospitals from 2004 to 2015.

In low-scoring hospitals, 3 percent of heart attack patients returned to the hospital for a new heart attack within 30 days. At one year, 13 percent were readmitted and about 8 percent died from cardiovascular causes.

Patients who were admitted to a teaching hospital had a 25 percent lower chance of readmission at one month. At one year, the chance of these patients suffering cardiovascular death was 10 percent lower than patients initially admitted to a non-teaching hospital.
