Background:
Interest in the association of vascular disease with COPD and pneumonia has increased, but there is a lack of research in this area with patients with bronchiectasis.
Methods:
A retrospective study of 400 patients attending a specialist bronchiectasis clinic in NHS Lothian (Edinburgh, UK) between May 2013 and September 2014 was conducted. The study assessed the prevalence of vascular disease (ischemic heart disease, cerebrovascular disease, peripheral vascular disease, and atrial fibrillation). Using multivariable models, independent risk factors were identified for vascular disease that developed following the diagnosis of bronchiectasis.
Results:
The study included 400 patients. There was preexisting vascular disease (ie, before the diagnosis of bronchiectasis) in 44 patients (11%), and vascular disease occurred after the diagnosis of bronchiectasis after a mean of 9.4 years (95% CI, 6.0-12.8 years) in 45 patients (11%). Independent factors associated with all-cause vascular disease after the diagnosis of bronchiectasis included male sex, hypertension, receiving long-term statin therapy, and having moderate-severity bronchiectasis or worse.
Conclusions:
In conclusion, bronchiectasis severity is independently associated with the development of vascular disease after the diagnosis of bronchiectasis. Future studies addressing the impact of primary and secondary prevention are warranted.

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
