Millions of people rely on daily medicines to manage heart disease. A new review of data from primary care clinics shows that stopping or restarting these drugs happens far more often than doctors expect. Over one year, between nine and 84 percent of patients stopped lipid-lowering therapies, while ten to 64 percent stopped blood pressure medicines. Restarting these drugs also occurred in twelve to 75 percent of cases for cholesterol and eighteen to 28 percent for blood pressure. These wide ranges mean the experience varies greatly from person to person.
The study looked at nearly 9.2 million patients in primary care settings. It found that age played a role, with people around 65 years old less likely to stop their medicines than younger or older patients. Women stopped cholesterol drugs more often, while men stopped blood pressure drugs more often for preventing heart issues. People from minority ethnic groups were also more likely to stop these treatments.
Socioeconomic factors like income influenced stopping rates, though the link was not always clear. The researchers noted that these findings come from observational data, so they show associations rather than direct causes. Two of the included studies had higher risks of bias due to missing information. Despite these limits, the patterns highlight a real need to understand why patients leave their treatment plans.
