Dyslipidemia and other cardiovascular risk factors in relation to manifest cardiovascular disease in patients with chronic obstructive pulmonary disease in the Canary Islands

Abstract

BackgroundCardiovascular disease has a negative impact on the vital prognosis of patients with chronic obstructive pulmonary disease (COPD), where dyslipidaemia (DLP) and arterial hypertension (AHT) are considered the most prevalent risk factors. The objective of this study was 1) to assess the relationship between diagnosed DLP and cardiovascular disease in COPD patients and compare it with other known cardiovascular risk factors and 2) to determine the relationship between the different cardiovascular comorbidities and the severity groups according to the GOLD 2017 classification. MethodsA cross-sectional, observational study was performed in 454 outpatients with COPD during their follow up. We calculated the prevalence of each of the cardiovascular comorbidities and the probability of each of the cardiovascular risk factors to occur jointly with a vascular disease (RRij). ResultsA total of 66.7% of the patients had DLP, whereby DLP was related to cerebrovascular accidents (CVA) (RRij 1.36, p = 0.0054), chronic kidney disease (CKD) (RRij 1.34, p = 0.00023), and peripheral arterial disease (PAD) (RRij 1.38, p = 0.00015). AHT was mostly related to CVA (RRij 1.41, p = 0.0014) and CKD (RRij 1.42, p < 0.0001). Type 2 diabetes mellitus (T2DM) correlated with PAD (RRij 1.90, p = 0.0001), heart failure (HF) (RRij 1.74, p = 0.0002), and CKD (RRij 1.76, p < 0.0001), and obesity was associated with HF (RRij 1.60, p = 0.0009) and CKD (RRij 1.54, p = 0.0001). ConclusionDLP was related to CVA, CKD, and PAD. AHT and T2DM are the conditions that mostly relate to HF and CVA.
