Occurrence of COPD in Patients with Respiratory Allergy: A Clinico-Spirometric Evaluation in a Tertiary Hospital, Kolkata

Chronic obstructive pulmonary disease and periprocedural complications in patients undergoing percutaneous coronary interventions

Background

The relationship between chronic obstructive pulmonary disease (COPD) and periprocedural complications of percutaneous coronary interventions (PCIs) is influenced by several factors. We aimed to investigate the association between COPD, its complication type and rate in patients undergoing PCI.

Methods

Data were prospectively collected using the Polish Cardiovascular Intervention Society national registry (ORPKI) on all PCIs performed in Poland between January 2015 and December 2016. COPD was present in 5,594 of the 221,187 patients undergoing PCI. We assessed the frequency and predictors of periprocedural complications in PCI.

Results

Patients with COPD were elder individuals (70.3 ± 9.9 vs. 67 ± 10.8 years; p < 0.05). We noted 145 (2.6%) periprocedural complications in the COPD group and 4,121 (1.9%) in the non-COPD group (p < 0.001). The higher incidence of periprocedural complications in the COPD patients was mainly attributed to cardiac arrest (p = 0.001), myocardial infarctions (p = 0.002) and no-reflows (p < 0.001). COPD was not an independent predictor of all periprocedural complications. On the other hand, COPD was found to be an independent predictor of increased no-reflow risk (odds ratio [OR] 1.447, 95% CI 1.085–1.929; p = 0.01), and at the same time, of decreased risk of periprocedural allergic reactions (OR 0.117, 95% CI 0.016–0.837; p = 0.03).

Conclusions

In conclusion, periprocedural complications of PCIs are more frequent in patients with COPD. COPD is an independent positive predictor of no-reflow and a negative predictor of periprocedural allergic reactions.
