Objective: Our aim was to assess the value of coronary artery calcium score (CACS) in the early diagnosis of coronary artery disease in Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage II chronic obstructive pulmonary disease (COPD) patients and to identify high-risk patients.
Methods: Forty-two patients with GOLD stage II COPD and 31 healthy control subjects were enrolled in the study. This study was designed as a prospective observational cross-sectional study. Pearson’s correlation coefficient was used for comparisons between groups. Criteria for stage II COPD diagnosis were forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of <70% and 50%≤FEV1<80%. Excluded from the study were individuals who had a previous diagnosis of coronary artery disease, GOLD stage I-III-IV COPD, or left ventricular systolic dysfunction.
Results: As compared with the control group, CACS values were significantly higher in the patient group (p=0.030 and 0.001, respectively). CACS was significantly higher in male patients with a positive family history, physical inactivity, long duration of disease, and low FEV1 (0.027, 0.008; 0.001 and 0.001; 0.001, respectively). Logistical regression analysis of sex, age, diabetes mellitus, hypertension, cigarette smoking, family history, physical inactivity, and FEV1 values showed that physical inactivity was independently correlated with high CACS [odds ratio (OR): 7; confidence interval (CI): 3–20; p=0.001].
Conclusion: The value of CACS is high in stage II COPD patients. Male stage II COPD patients with a disease duration of 10 years, physical inactivity, and/or a positive family history should be monitored for early stage coronary artery disease and coronary events, regardless of risk factors such as diabetes, hypertension, and hyperlipidemia.
