Gamma glutamyltransferase, inflammation and cardiovascular risk factors in isolated coronary artery ectasia

Introduction and Objective: There are conflicting data on the prevalence of cardiovascular risk factors in coronary artery ectasia (CAE). It is unclear whether CAE is associated with high-sensitivity C-reactive protein (hs-CRP) and gamma glutamyltransferase (GGT). We therefore investigated major car...

Description
Summary:Introduction and Objective: There are conflicting data on the prevalence of cardiovascular risk factors in coronary artery ectasia (CAE). It is unclear whether CAE is associated with high-sensitivity C-reactive protein (hs-CRP) and gamma glutamyltransferase (GGT). We therefore investigated major cardiovascular risk factors, serum GGT and hs-CRP levels in a large population of patients with CAE. Methods: A total of 167 patients with isolated CAE and 150 controls with normal coronary arteries were selected from 10 505 patients undergoing coronary angiography. Serum GGT and hs-CRP levels were evaluated in addition to cardiovascular risk factors including family history, obesity, smoking, diabetes, hypertension and hyperlipidemia. Results: Hypertension and obesity were slightly more prevalent in CAE patients than in controls, whereas diabetes was slightly less frequent in CAE patients. Other risk factors were similar. Serum GGT (22 [17–42] vs. 16 [13–21] U/l, p=0.001) and hs-CRP (2.9 [1.9–3.6] vs. 1.4 [1.1–1.8] mg/l, p=0.001) levels were higher in CAE patients than in controls. The presence of CAE was independently associated with diabetes (OR: 0.44, 95% CI: 0.20–0.95, p=0.04), obesity (OR: 2.84, 95% CI: 1.07–7.56, p=0.04), GGT (OR: 1.08, 95% CI: 1.03–1.12, p=0.001) and hs-CRP levels (OR: 3.1, 95% CI: 2.1–4.6, p=0.001). In addition, GGT and hs-CRP levels were higher in diffuse and multivessel ectasia subgroups than focal and single-vessel ectasia subgroups (each p<0.05). Conclusions: Our findings show that CAE can be independently and positively associated with obesity, GGT and hs-CRP levels, but inversely with diabetes. Moreover, its severity may be related to GGT and hs-CRP levels. Resumo: Introdução e objetivos: Existem dados contraditórios relativamente à prevalência dos fatores de risco cardiovascular na ectasia da artéria coronária (EAC). Não é claro se a EAC possa estar associada à proteína C reativa de alta-sensibilidade (PCR-as) e à gama glutamiltransferase (gama-GT). Assim examinámos fatores de risco cardiovascular major, a gama-GT sérica e os níveis de PCR-as numa população mais alargada de doentes com EAC. Métodos: Foram selecionados um total de 167 doentes com EAC isolada e 150 casos-controlo com artérias coronárias normais dos 10 505 doentes submetidos a angiografia coronária. A gama-GT sérica e os níveis de PCR-as foram avaliados para além dos fatores de risco cardiovascular incluindo a história familiar, obesidade, tabagismo, diabetes, hipertensão e hiperlipidemia. Resultados: A hipertensão e a obesidade foram ligeiramente mais prevalentes nos doentes com EAC do que nos casos-controlo enquanto a diabetes foi menos frequente nos doentes com EAC. Os outros fatores de risco foram semelhantes. Os níveis de gama-GT sérica [22 (17-42) versus 16 (13-21) U/L, p =0,001] e de PCR-as [2,9 (1,9-3,6) versus 1,4 (1,1-1,8) mg/L, p =0,001] foram superiores nos doentes com EAC do que nos casos-controlo. A presença de EAC foi independentemente associada à diabetes (OR: 0,44, IC 95%: 0,20-0,95, p =0,04), obesidade (OR: 2,84, IC 95%: 1,07-7,56, p =0,04), gama-GT (OR:1,08, IC 95%: 1,03-1,12, p =0,001) e níveis de PCR-as (OR:3,1, IC 95%: 2,1-4,6, p =0,001). Além disso, os níveis de GGT e de PCR-as foram superiores nos subgrupos de ectasia difusa e mutivasos do que nos subgrupos de ectasia focal e de um vaso (cada p < 0,05). Conclusão: As nossas conclusões mostram que a EAC pode ser certamente associada à obesidade, aos níveis de gama-GT e de PCR-as, mas de modo inverso à diabetes. Além disso a sua gravidade pode estar associada aos níveis de gama-GT e de PCR-as.
