Background:
Previously, most researchers explored the association between chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD). This study investigates the distinct influence of COVID-19 vaccination status on patients with both conditions.
Objective:
We investigate the relationship between COPD and CVD in a cohort of 838 individuals who presented with both conditions. Our aim is to understand how these conditions interact and how COVID-19 vaccination status affects patient outcomes.
Methods:
A retrospective analysis was conducted on 838 patients with COPD and CVD treated at DHQ Hospital in Muzaffargarh, Punjab, Pakistan, from November 2022 to April 2023. We employed multiple logistic regression and the Wilcoxon signed-rank test to assess the odds ratio and relative risk of COPD in patients with-CVD under various conditions. Additionally, we analyzed time-to-death and survival using Kaplan-Meier methods.
Results:
Findings reveal a 7.95 times higher risk of death in patients without COVID-19 vaccination compared with those who were vaccinated (95% CI, 6.12-10.33). Conversely, COVID-19-vaccinated patients exhibited a 0.221 times lower risk of recovery than their nonvaccinated counterparts (95% CI, 0.08-0.60). We also observed significant differences in time-to-death and recovery based on the presence of COPD and CVD, with vaccinated patients generally experiencing milder disease.
Conclusion:
Our study assessed the impact of COVID-19 vaccination status on patient outcomes in patients with overlapping COPD and CVD. Individuals diagnosed with COPD and CVD display significant differences in terms of their probability of survival, with those who have received vaccinations.

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.

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...
