Final answer:
The Bally et al BMJ study on NSAIDs and MI showed an increased risk of heart attack associated with the use of NSAIDs.
Step-by-step explanation:
The Bally et al BMJ study on NSAIDs and MI (Myocardial Infarction) showed that there is an increased risk of heart attack associated with the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The study found that NSAIDs, including drugs like ibuprofen and naproxen, can raise the risk of having a heart attack by about 20-50%. This risk is particularly pronounced in the first month of use and in individuals with a history of heart disease.
