Introduction:
Iron deficiency (ID) has not been associated with pulmonary embolism (PE). The aim was to assess whether ID is associated with an increased likelihood of developing PE within the subsequent 12 months.
Patients And Methods:
Retrospective observational study. Patients with PE during follow-up were selected as cases, and those without the event as controls. Patients with chronic diseases, cancer, fractures, or recent hospital admissions were excluded.
Results:
A total of 43 cases and 199 controls were enrolled. The mean age was 61±21 years. ID increased the risk of PE at 12 months with an odds ratio of 2.15 (95% confidence interval (CI95%): 1.01-4.58; P=.046). Survival analysis showed more than a two-fold increase in the risk of developing PE in the presence of prior ID (hazard ratio: 2.37 (CI95%: 1.30-4.31; P=.05)).
Conclusion:
ID may represent an increased risk of PE in the 12 months following its detection.

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.

Two factors primarily cause thromboembolic conditions.

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
