Many heart attack survivors stop essential medication, raising mortality risk

An analysis of data from Sweden's Swedeheart registry reveals that more than half of individuals who survive a heart attack cease their medication regimen, which includes agents that lower cholesterol, reduce blood pressure, and thin the blood. Patients who stopped treatment during the first year after their event exhibited a mortality risk up to double that of patients who continued therapy over the subsequent three years.

According to senior author Emil Hagström, reasons for discontinuation range from a sense of recovery to concerns about side effects or doubts about necessity. A further challenge is the routine transfer of patients from specialized cardiac units to general primary-care services after a year, a shift that can lead to loss of critical information and weaker monitoring of drug adherence. While the study cannot definitively prove causation, the findings echo larger clinical trials that have demonstrated the life-saving benefits of these medications. The research was published in the European Journal of Preventive Cardiology and received partial funding from the Heart-Lung Foundation.
