Shortness of breath is a very unpleasant sensation and people with chronic obstructive pulmonary disease (COPD) have it chronically. It is not something that you can ever get used to, breath being so essential to life, and the disease worsens relentlessly; without medical attention one dies slowly of suffocation. That is a horrible way to die. Though COPD will become less common in time, thanks to a reduction in smoking (except in Colorado), it is still the third most common cause of death among adults in America.
As yet there is no cure and perhaps there will never be one, short of lung transplant; but it has been reported many times in the medical press that statins, drugs taken to reduce the risk of heart attack among the otherwise susceptible, ameliorate the symptoms and reduce the frequency of acute exacerbations.
Patients who have COPD and are taking statin drugs to reduce their risk of heart attack or stroke have been thought to experience fewer acute exacerbations of the disease and as a consequence to live longer. There is biological plausibility to this observation, for statins have an anti-inflammatory effect and exacerbations of COPD are caused by infection and its consequent inflammation.
