A common bronchodilator drug has been linked with an increased risk of cardiovascular deaths among COPD patients in a study.
The US study looked at the cause of death of 145,000 veterans newly diagnosed with COPD from 1999-2003.
Findings showed that those diagnosed with COPD using ipratropium were 34% more likely to die of myocardial infarction or arrhythmia than COPD patients using only albuterol or patients not using any treatment.
Lead author Todd Lee, research assistant professor in the Institute for Healthcare Studies at Northwestern University’s Feinberg School of Medicine, said: ‘This medication may be having some systemic cardiovascular effect that is increasing the risk of death in COPD patients.’
