Patients with myasthenia gravis (MG) may face a more difficult recovery after cardiac surgery, although their risk of death during the hospital stay does not appear to be higher than that of patients without the condition.
These findings come from a recent U.S. study that assessed in-hospital outcomes in patients with MG undergoing cardiac surgery. The nationwide study, published in BMC Anesthesiology, analyzed hospital data collected over 15 years. Researchers compared adults who underwent major heart procedures (such as coronary artery bypass grafting or valve replacements) to see how those with MG fared compared to those without the disorder.
Since MG causes the immune system to disrupt communication between nerves and muscles, it can lead to weakness in the muscles used for breathing and swallowing, which are critical during surgical recovery.

According to the data, patients with MG stayed in the hospital for about one extra day on average. They were also 30% more likely to have major complications after surgery and 35% more likely to require additional care following discharge, such as going to a rehabilitation center or nursing facility instead of returning directly home.
The authors suggested that hospitals use specialized care plans to better manage the risks.
“These findings support implementing enhanced perioperative protocols and multidisciplinary care pathways to mitigate excess complications, streamline recovery and optimize resource use in this high-risk population,” they wrote. In practice, this could mean patients with MG being closely monitored by specialists such as neurologists, surgeons and respiratory therapists before, during and after surgery so that complications can be caught and treated as early as possible.
Despite these challenges, the study offered a reassuring finding: there was no significant difference between the groups in the rate of in-hospital deaths. This suggests that while the road to recovery may be more complex for patients with MG, the procedures themselves remain just as survivable.
