Cím:High-fat diet-induced obesity leads to increased NO sensitivity of rat coronary arterioles : role of soluble guanylate cyclase activation / Jebelovszki, E., Kiraly, C., Erdei, N., Feher, A., Pasztor, T. E., Rutkai, I., Forster, T., Edes, I., Koller, A., Bagi, Z.

Megjegyzések:The impact of obesity on nitric oxide (NO)-mediated coronary microvascular responses is poorly understood. Thus NO-mediated vasomotor responses were investigated in pressurized coronary arterioles ( approximately 100 microm) isolated from lean (on normal diet) and obese (fed with 60% of saturated fat) rats. We found that dilations to acetylcholine (ACh) were not significantly different in obese and lean rats (lean, 83 +/- 4%; and obese, 85 +/- 3% at 1 microM), yet the inhibition of NO synthesis with N(omega)-nitro-l-arginine methyl ester reduced ACh-induced dilations only in vessels of lean controls. The presence of the soluble guanylate cyclase (sGC) inhibitor oxadiazolo-quinoxaline (ODQ) elicited a similar reduction in ACh-induced dilations in the two groups of vessels (lean, 60 +/- 11%; and obese, 57 +/- 3%). Dilations to NO donors, sodium nitroprusside (SNP), and diethylenetriamine (DETA)-NONOate were enhanced in coronary arterioles of obese compared with lean control rats (lean, 63 +/- 6% and 51 +/- 5%; and obese, 78 +/- 5% and 70 +/- 5%, respectively, at 1 microM), whereas dilations to 8-bromo-cGMP were not different in the two groups. In the presence of ODQ, both SNP and DETA-NONOate-induced dilations were reduced to a similar level in lean and obese rats. Moreover, SNP-stimulated cGMP immunoreactivity in coronary arterioles and also cGMP levels in carotid arteries were enhanced in obese rats, whereas the protein expression of endothelial NOS and the sGC beta1-subunit were not different in the two groups. Collectively, these findings suggest that in coronary arterioles of obese rats, the increased activity of sGC leads to an enhanced sensitivity to NO, which may contribute to the maintenance of NO-mediated dilations and coronary perfusion in obesity.

Cím:Renin overexpression leads to increased titin-based stiffness contributing to diastolic dysfunction in hypertensive mRen2 rats / Árpád Kovács, Gábor Á.

Megjegyzések:Hypertension (HTN) is a major risk factor for heart failure. We investigated the influence of HTN on cardiac contraction and relaxation in transgenic renin overexpressing rats (carrying mouse Ren-2 renin gene, mRen2, n = 6). Blood pressure (BP) was measured. Cardiac contractility was characterized by echocardiography, cellular force measurements, and biochemical assays were applied to reveal molecular mechanisms. Sprague-Dawley (SD) rats (n = 6) were used as controls. Transgenic rats had higher circulating renin activity and lower cardiac angiotensin-converting enzyme two levels. Systolic BP was elevated in mRen2 rats (235.11 ? 5.32 vs. 127.03 ? 7.56 mmHg in SD, P < 0.05), resulting in increased left ventricular (LV) weight/body weight ratio (4.05 ? 0.09 vs. 2.77 ? 0.08 mg/g in SD, P < 0.05). Transgenic renin expression had no effect on the systolic parameters, such as LV ejection fraction, cardiomyocyte Ca(2+)-activated force, and Ca(2+) sensitivity of force production. In contrast, diastolic dysfunction was observed in mRen2 compared with SD rats: early and late LV diastolic filling ratio (E/A) was lower (1.14 ? 0.04 vs. 1.87 ? 0.08, P < 0.05), LV isovolumetric relaxation time was longer (43.85 ? 0.89 vs. 28.55 ? 1.33 ms, P < 0.05), cardiomyocyte passive tension was higher (1.74 ? 0.06 vs. 1.28 ? 0.18 kN/m(2), P < 0.05), and lung weight/body weight ratio was increased (6.47 ? 0.24 vs. 5.78 ? 0.19 mg/g, P < 0.05), as was left atrial weight/body weight ratio (0.21 ? 0.03 vs. 0.14 ? 0.03 mg/g, P < 0.05). Hyperphosphorylation of titin at Ser-12742 within the PEVK domain and a twofold overexpression of protein kinase C-? in mRen2 rats were detected. Our data suggest a link between the activation of renin-angiotensin-aldosterone system and increased titin-based stiffness through phosphorylation of titin's PEVK element, contributing to diastolic dysfunction.

Cím:Design and rationale for the Myocardial Stem Cell Administration After Acute Myocardial Infarction (MYSTAR) Study : a multicenter, prospective, randomized, single-blind trial comparing early and late intracoronary or combined (percutaneous intramyocardial and intracoronary) administration of nonselected autologous bone marrow cells to patients after acute myocardial infarction / Nyolczas, N., Gyongyosi, M., Beran, G., Dettke, M., Graf, S., Sochor, H., Christ, G., Edes, I., Balogh, L., Krause, K.

Megjegyzések:Previous data suggest that bone marrow-derived stem cells (BM-SCs) decrease the infarct size and beneficially affect the postinfarction remodeling. METHODS: The Myocardial Stem Cell Administration After Acute Myocardial Infarction Study is a multicenter, prospective, randomized, single-blind clinical trial designed to compare the early and late intracoronary or combined (percutaneous intramyocardial and intracoronary) administration of BM-SCs to patients after acute myocardial infarction (AMI) with reopened infarct-related artery. The primary end points are the changes in resting myocardial perfusion defect size and left ventricular ejection fraction (gated single photon emission computed tomography [SPECT] scintigraphy) 3 months after BM-SCs therapy. The secondary end points relate to evaluation of (1) the safety and feasibility of the application modes, (2) the changes in left ventricular wall motion score index (transthoracic echocardiography), (3) myocardial voltage and segmental wall motion (NOGA mapping), (4) left ventricular end-diastolic and end-systolic volumes (contrast ventriculography), and (5) the clinical symptoms (Canadian Cardiovascular Society [CCS] anina score and New York Heart Association [NYHA] functional class) at follow-up. Three hundred sixty patients are randomly assigned into 1 of 4 groups: group A, early treatment (21-42 days after AMI) with intracoronary injection; group B, early treatment with combined application; group C, late treatment (3 months after AMI) with intracoronary delivery; and group D, late treatment with combined administration of BM-SCs. Besides the BM-SCs therapy, the standardized treatment of AMI is applied in all patients. CONCLUSIONS: The Myocardial Stem Cell Administration After Acute Myocardial Infarction Trial is the first randomized trial to investigate the effects of the combined (intramyocardial and intracoronary) and the intracoronary mode of delivery of BM-SCs therapy in the early and late periods after AMI.

Cím:Effect of timing of clopidogrel administration on 30-day clinical outcomes : 300-mg loading dose immediately after coronary stenting versus pretreatment 6 to 24 hours before stenting in a large unselected patient cohort / Szuk, T., Gyongyosi, M., Homorodi, N., Kristof, E., Kiraly, C., Edes, I.

Megjegyzések:The aim of our prospective multicenter Clopidogrel Registry was to evaluate the efficacy and safety of a 300-mg loading dose of clopidogrel at the time of ad hoc stenting in patients with suspected coronary artery disease who were not pretreated with clopidogrel for any reason, and to compare the 30-day clinical event rates with the outcome of patients pretreated with a loading dose of clopidogrel 6 to 24 hours before stenting. METHODS: Between March 2002 and February 2004, 4160 consecutively included patients received a 300-mg loading dose of clopidogrel immediately after (group 1, n = 2679) or 6 to 24 hours before stenting (group 2, n = 1481). RESULTS: The primary end point (triple composite end point of acute myocardial infarction, all-cause death, and urgent repeat target vessel revascularization) at 30 days occurred in 4.74% versus 2.77% in groups 1 and 2, respectively (P = .002). The secondary end point events, the stent thrombosis, occurred significantly more frequently in group 1, with a trend toward increase in incidence of death, target vessel revascularization, or need for glycoprotein IIb/IIIa antagonists during percutaneous coronary intervention. Pretreatment with clopidogrel was associated with more major bleeding (secondary safety end point) (0.41% vs 1.35% in groups 1 and 2, respectively; P = .001). CONCLUSIONS: The results of our multicenter prospective Clopidogrel Registry demonstrate lower efficacy of a 300-mg loading dose of clopidogrel at the time of stenting compared with pretreatment 6 to 24 hours before percutaneous coronary intervention on the 30-day composite clinical end point in the large unselected patient cohort, which suggests the benefit of clopidogrel pretreatment in all incoming patients with suspected significant coronary artery disease scheduled for coronary angiography
