Smoking has long been known to damage the lungs and increase the risk of many serious diseases. One of the most common conditions linked to smoking is chronic obstructive pulmonary disease, or COPD.
This is a long-term lung disease that makes it hard to breathe. It includes conditions such as chronic bronchitis and emphysema. COPD affects more than 30 million people in the United States and is one of the leading causes of death worldwide.
People who smoke or used to smoke often have other health problems as well. Many of them take medicines like statins to lower cholesterol and aspirin to prevent heart disease.
These medicines are widely used and are considered important for protecting heart health. However, scientists are now starting to look at how these drugs may affect other parts of the body, including muscles.
Muscle loss is a serious issue for smokers and former smokers, especially those with COPD. Over time, people with this condition may lose muscle strength and size. This can make it harder for them to move, stay active, and even breathe properly.
Strong muscles are important for everyday activities, and losing muscle can lead to poorer health and lower quality of life.
A new study has explored how common medicines might influence muscle loss in this group of people. The research was published in January 2025 in the journal Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation.
The study was led by Dr. Toru Shirahata, a lung specialist at Brigham and Women’s Hospital and Harvard Medical School. His team wanted to understand whether statins and aspirin have any effect on chest muscles in smokers and former smokers.
To do this, the researchers used data from a large project called the COPD Genetic Epidemiology study, also known as COPDGene. They looked at chest CT scans from 4,191 participants. These scans were taken at two different time points, which allowed the researchers to measure changes in muscle size and quality over time.
The focus was on the pectoralis muscles, which are the muscles in the chest. These muscles play an important role in breathing and upper body strength. By comparing the scans, the researchers could see how much muscle was lost and whether certain medications were linked to these changes.
The results showed an interesting pattern. People who were taking statins tended to have less muscle loss over time. This suggests that statins might help protect muscle in smokers and former smokers. On the other hand, people who were taking aspirin showed more muscle loss compared to those who were not taking it.
Dr. Shirahata explained that many smokers and former smokers are prescribed both statins and aspirin because they often have conditions like heart disease or diabetes. Because of this, it is important to understand how these medications affect the body beyond their main purpose.
The findings do not prove that statins directly protect muscle or that aspirin directly causes muscle loss. The study only shows a connection between these medicines and changes in muscle seen on scans. More research is needed to confirm these results and to understand why these effects may happen.
Even so, the study raises important questions for doctors. If future research supports these findings, doctors may need to think more carefully about how they use aspirin in people who are at risk of muscle loss. At the same time, statins might offer an added benefit by helping to preserve muscle.
This research also highlights the importance of looking at the whole person when choosing treatments. Medicines that are helpful for one condition may have unexpected effects on other parts of the body. By understanding these effects, doctors can make better decisions and provide more personalized care.
For people with COPD, maintaining muscle strength is very important. Strong muscles can help improve breathing, support daily activities, and improve overall health. This means that even small changes in muscle loss can have a big impact over time.
In the future, researchers may explore new ways to protect muscle health in smokers and former smokers. This could include adjusting medications, improving nutrition, or encouraging safe physical activity.
Overall, this study provides new insight into how common heart medicines may affect muscle health in a group of people who are already at high risk. It opens the door for more research and better treatment strategies that consider both heart health and muscle health together.
