Megjegyzések:	Objective: Saphenous venous grafts (SVGs) are established choices for coronary artery bypass grafting (CABG); however, their lumen patencyis limited. Our goal was to investigate the risk factors of SVG degeneration.Methods: Seventy-five patients (mean age, 57.5?10.4 years) with 133 SVG conduits who had cardiac catheterization ?1 year after CABG wereselected; follow-up period was 67.6?36.8 months. Patients were divided into 3 groups according to angiographic status at follow up [intact: <20%(n=23); narrowed: 20?99% (n=24); and occluded (n=28)]. Baseline clinical conditions were evaluated in relation to follow-up angiography. Asonset date of chronic total occlusions is usually uncertain, they arise typically from thrombotic lesions; thus, their value in evaluation is limited.Results: There were no significant differences between the 3 groups in clinical parameters. Linear correlation analysis found significant (p<0.01)positive connection of SVG disease (luminal diameter reduction 20?99%) with C-reactive protein (CRP) and homocysteine (Hcy), as well asbetween CRP and Hcy. Multiple regression analysis showed plasma Hcy level to be significantly related to graft diameter reduction normalizedto time elapsed until angiography in narrowed grafts: 1 ?mol/L increase of Hcy was associated with 0.053%/month decrease in lumen diameter(p<0.01; R2=0.428); extrapolating: +10 ?mol/L higher Hcy level during 5 years is associated with 32.1% lumen reduction.Conclusion: Medium- to long-term SVG degeneration is related to elevated plasma total Hcy in patients with sub-occlusive graft stenosis, whilein cases with intact SVGs, the beneficial local flow conditions may protect the grafts from degeneration.

Megjegyzések:	There are only very few epidemiological data about homocysteine levels in patients suffering from cardiovascular (CV) disease in Hungary, however, homocysteine is a newly recognized, independent risk factor of CV diseases. AIM OF THE STUDY: Therefore, in the present study, data of 1010 East-Hungarian patients with signs of CV disease were analyzed retrospectively for correlation between the level of homocysteine and CV diseases, laboratory parameters, as well as genetic differences. PATIENTS AND METHODS: From the studied patient population a control ("healthy") group has been selected according to the following criteria: lack of previous stroke or stenosis of the carotid arteries or the lower extremities, lack of coronary artery stenosis more than 50%, no previous coronary intervention or an angiography diagnosed progression of the coronary atherosclerosis. RESULTS: The level of homocysteine showed statistically significant negative linear correlation with HDL-cholesterol and the anti-atherogenic ApoAI, and showed a positive correlation with CRP and FXIII activities in the entire patient population. When compared to the control group, homocysteine level was significantly higher in patients with previous stroke or acute myocardial infarction, coronary stenosis, progressive coronary disease, physical inactivity, MTHFR gene polymorphism, low folate or vitamin B12 level in both men and women. In patients with type II diabetes the level of homocysteine was significantly higher only in women. CONCLUSIONS: It can be concluded that the level of homocysteine in patients suffering from various CV diseases is high in Hungary. This may have a prognostic value, and shows that reduction of homocysteine level in these patients may be beneficial.újratöltve - BIBFORM006752

Megjegyzések:	Our aim was to investigate the association of elevated homocysteine (Hcy) and lipoprotein(a) Lp(a) with the prevalence of coronary artery disease (CAD) and myocardial infarction (MI) and to investigate their interaction in both genders.MATERIALS AND METHODS:955 (male/female: 578/377) consecutive patients admitted for coronary angiography were enrolled in the study. Lp(a), Hcy, vitamin B12, folic acid, MTHFR C677T polymorphism and traditional risk factors were determined.RESULTS:619 patients had significant (?50%) stenosis (CAD+) and 341 had MI (MI+). CAD-MI- cases (n=302) were considered as controls. Adjusted Hcy levels were significantly elevated only in the female CAD+MI+group that was related to decreased vitamin B12 levels. Lp(a) was elevated in the CAD+MI+group of both genders. Folic acid levels and MTHFR T677 allele frequency did not show significant difference. Moderate hyperhomocysteinemia (Hcy >15?mol/L) or elevated Lp(a) (>300mg/L) increased the risk of CAD (OR 2.27, CI 1.36-3.80 and OR 1.64, CI 1.03-2.61, respectively) and MI (OR 2.52, CI 1.36-4.67 and OR 1.89, CI 1.06-3.38, respectively) only in women. Only simultaneous but not isolated elevation of Hcy and Lp(a) conferred a significant, 3.6-fold risk of CAD in females and even higher (11-fold) risk in young females, which suggested an interactive effect.CONCLUSIONS:Moderate hyperhomocysteinemia or elevated Lp(a) level associated with a risk of CAD and MI only in women. While isolated elevation of one of the two parameters represented a mild risk of CAD, their combined elevation highly increased the risk in females. No such effect was observed in males.

Cím:	Effects of ad hoc clopidogrel loading versus pre-treatment on P-selectin expression after coronary stent implantation / Tibor Szuk, Béla Nagy, Zsuzsanna Bereczky, Zsolt Koszegi, István Edes, János Kappelmayer
Dátum:	2006
ISSN:	0953-7104
Megjegyzések:	Stents represent a thrombogenic surface where one of the earliest events is the deposition of platelets. Activated platelets express neoepitopes that enable them to form homo- and heterotypic aggregates and activate the coagulation system. In this study, we investigated the effects of ad hoc clopidogrel treatment compared to a clopidogrel pretreated group on platelet P-selectin expression. We found that after stent implantation in the ad hoc treated group, P-selectin expression decreased after 1 h, while the initial decrease in platelet count normalized after 4 h. Aspirin non-responsiveness did not influence the results. These data point to the beneficial effect of clopidogrel treatment in reducing platelet reactivity during stenting.
