A reduced lung function and respiratory tract disorders such as chronic obstructive pulmonary disease (COPD) increase the risk of heart failure, a recent study found.
In patients with heart failure, the heart can not pump enough blood to meet the needs of the organism.
For the new study, researchers analyzed data on 16,000 people in USA States. 45 to 64 years who participated in the study of atherosclerosis risk in communities and who were followed for a mean of fifteen.
The results showed that long-term risk of developing heart failure increased as decreased lung function. Lung function was determined by using a test known as forced expiratory volume (FEV1) by spirometry, which measures how much air a person can exhale in one second.
The findings did not change even after the researchers accounted for age, history of heart disease or cardiovascular disease risk due to factors such as smoking.
The results, published in the February 25 edition of the European Journal of Heart Failure, support a relationship between low lung capacity and development of heart failure, said first author Dr. Sunil Agarwal, University North Carolina at Chapel Hill.
?That risk, given a low FEV1, is of similar magnitude (or perhaps greater) than that seen with common risk factors and modifiable as diabetes or hypertension. The public health implications are immense, especially given that smoking and Air pollution adversely affect lung function, ?Agarwal said in a news release from the journal.
?So it will be important to determine whether interventions to sustain or improve the FEV1 are associated with a lower risk of heart failure,? said Agarwal.
The researchers noted that it is common for heart failure patients with COPD, and vice versa. But only recently has shown that COPD is a factor after long-term risk of heart failure.
An editorial accompanying the study said the report ?strengthens the hypothesis that pulmonary obstruction itself is an important risk factor for heart failure.?
The editorial also noted that ?thinking about heart failure as a possible cause in any patient with shortness of breath and fatigue, or an increase in these symptoms, regardless of other elements of disease such as COPD, mean that doctors should ?rethink ?clinical reasoning ?and reconsider the plan of pharmacological treatment.
Although the study found an association between poor lung function and heart failure did not demonstrate that there is a cause and effect.
