Background:
examine baseline dyspnoea and subsequent 10-year mortality adjusting for age and gender and determine whether dyspnoea is related to early or late mortality or both. Examine the relationship between dyspnoea and mortality adjusting for confounding effects of underlying diseases.
Methods:
we sent modified Medical Research Council (MRC) dyspnoea questionnaire to identify breathlessness in 1,404 randomly selected subjects from general practitioner lists of 5,002 subjects aged 70 years and over living in the community. A further random sample of 500 subjects underwent clinical assessment including pulmonary function tests, electrocardiography and echocardiography. Subjects were followed up for 10 years and all deaths were recorded, using general practitioner records and the local death registry.
Results:
prevalence of dyspnoea was 32.3%. Breathlessness was associated with early mortality and late mortality. At 2 years 10.1% breathless subjects died compared with 3.4% non-breathless (P=0.02). At 10 years 63.3% breathless had died compared with 40.5% non-breathless (P=0.0001). Increasing grade of MRC dyspnoea was associated with 10 mortality. Advancing age (OR: 2.27), male gender (OR: 1.95), breathlessness (OR: 2.53), left ventricular dysfunction (OR: 5.01) and chronic airways disease (OR: 3.04) were all significantly associated with 10-year mortality. After adjustment of age, gender and underlying diseases breathlessness was associated with 10-year mortality (P=0.02).
Conclusion:
dyspnoea is a predictor of early and late mortality and increasing grade of dyspnoea is associated with a higher rate of mortality. Dyspnoea is an independent risk factor for mortality after adjustment for age, gender and underlying diseases.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

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...
