Article: Association between laboratory markers and presence of coronary artery disease.
[show abstract] [hide abstract]
ABSTRACT: The aim of this paper is to elucidate the relation between laboratory markers and coronary artery disease (CAD). The study involved 1254 consecutive patients with suspected or known CAD referred for coronary angiography. The blood samples including blood cell count, C-reactive protein, fibrinogen, uric acid, creatinine, and lipid spectrum were obtained after overnight fasting. One hundred and thirty-three patients were excluded due to incomplete records or inacceptable laboratory values. Differences among groups were tested with one-way ANOVA and Bonferroni post-hoc test for continuous variables and with chi-square test for categorical variables. Univariate and multivariate logistic regression was adopted for the analysis of risk factors and development of models for classification of patients into clinical categories. The linear logistic regression showed association of patient's biochemical markers with the presence of disease. Both acute and chronic CAD were associated with leukocyte count (Odds ratios 1.45 and 1.26), CRP (1.13; 1.05), fibrinogen (4.23; 1.95), uric acid (1.27; 1.38), creatinine (1.04; 1.04), HDL cholesterol (0.07; 0.12), triglycerides (1.4; 1.52) and glucose (1.56; 1.39). Presence of insignificant atherosclerosis was influenced only by fibrinogen (OR 1.73), creatinine (1.02), HDL cholesterol (0.5) and glucose level (1.23). There was no difference between one- and multivessel disease in laboratory values. Leukocyte count, CRP level, triglycerides and uric acid are associated with the presence of both acute and chronic ischaemic heart disease, but not with number of stenosed vessels. In addition, glycemia, HDL cholesterol and namely fibrinogen and creatinine have relation to occurence of insignificant atherosclerosis.Biomedical papers of the Medical Faculty of the University Palacky, Olomouc, Czechoslovakia 09/2010; 154(3):227-33. -
Article: ACE gene insertion/deletion polymorphism has a mild influence on the acute development of left ventricular dysfunction in patients with ST elevation myocardial infarction treated with primary PCI.

ABSTRACT: We evaluated the associations among angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism, ACE activity and post-myocardial infarction (MI) left ventricular dysfunction and acute heart failure (AHF) early after presentation with MI with ST-segment elevation (STEMI). A total of 556 patients with STEMI treated by primary PCI (421 patients without AHF and 135 patients with AHF) were the study population. The activity of BNP, NT-ProBNP and ACE were measured at hospital admission and 24 h after MI onset. Left ventricular angiography was done before PCI; echocardiography was undertaken between the third and fifth day after MI. In comparison with the II genotypes group, the DD/ID group had a higher level of ACE activity upon hospital admission (p < 0.001). We found a significantly higher level of ACE activity in patients with moderate LV dysfunction (EF 40-54%) in comparison both with patients with preserved LV function (EF ≥ 55%) and with patients with severe LV dysfunction (p = 0.028). A non-significant trend towards a higher incidence of mild AHF (22.1% vs. 16.02%, p = 0,093), a significantly higher value of end-systolic volume (ESV/BSA) (30.0 ± 12.3 vs. 28.5 ± 13.0; p < 0.05) and lower EF (50.2 ± 11.1 vs. 52.7 ± 11.7; p < 0.05) in the DD/ID genotypes group was noted. Even after multiple adjustments according to multivariate models, the EF for the DD/ID group remained significantly lower (p = 0,033). The DD/ID genotypes were associated with a significantly higher risk of EF <45% (OR 2.04 [95% CI 1.28; 3.25]). These results suggest that the I/D polymorphism of ACE is associated with the development of LV dysfunction in the acute phase after STEMI. We demonstrated for the first time an association of the low ACE activity with the severe LV dysfunction, although patients with moderate LV dysfunction had higher level ACE activity than patients with preserved LV function.BMC Cardiovascular Disorders 01/2010; 10:60. · 1.52 Impact Factor
