Study of medication safety in heart patients during COVID-19

Researchers want to understand how often older patients with heart disease receive medications that may not be safe for them, especially during the COVID-19 pandemic. This study will look at medical records from a hospital system in Russia to see how many patients are taking multiple medications together and whether those combinations could cause problems. The goal is to find ways to keep patients safer.

During the pandemic, many older heart patients may have received more medications than necessary or combinations that don't work well together. By identifying how often this happens, doctors hope to improve how they prescribe medications and prevent serious side effects.
