Increased expression of CD11a and CD45 on leukocytes and decreased serum TNF-alpha levels in patients with isolated coronary artery ectasia.

Background: Aneurysm and ectasia have similar pathological pathways. TH2-associated cytokines are stimulated by aneurismal tissue and correspondingly lack mediators associated with TH1 response. In this study, we measured serum TNF-alpha and IL-18 levels which are strong TH1 stimulating cytokines and also investigated the expression of CD11a, CD11b, CD18 adhesion molecules and CD45 on leukocytes in patients with coronary artery ectasia (CAE) and controls with normal coronary arteries (NCA).

Iloprost downregulates expression of adhesion molecules and reduces renal injury induced by abdominal aortic ischemia-reperfusion.

The aim of this study was to examine the effect of iloprost in renal injury induced by abdominal aortic ischemia-reperfusion (IR) and how it can modulate the expression of adhesion molecules during this effect. Twenty-four Wistar-Albino rats were randomized into three groups (n=8) as follows: control (sham laparotomy), aortic IR (120 min ischemia and 120 min reperfusion), and aortic IR + iloprost (0.45 microg/kg/hr intravenous infusion during 120 min reperfusion).

Statin use before by-pass surgery decreases the incidence and shortens the duration of postoperative atrial fibrillation.

Background: The aim of the present observational study is to search the incidence of postoperative atrial fibrillation (AF) in patients with or without preoperative statin treatment.

Methods And Results: The population consisted of 362 consecutive patients (267 on and 95 not on statin). Diabetes mellitus was more frequent in statin group (p = 0.

Efficiency of prostacyclin in the treatment of protamine-mediated right ventricular failure and acute pulmonary hypertension.

Protamine is used after cardiopulmonary bypass was stopped in order to reverse the anticoagulant effects of heparin administered during open-heart operations. Adverse hemodynamic responses to protamine are common, ranging from minor perturbations to cardiovascular collapse. The aim of the present study was to investigate whether a prostacyclin is effective in the treatment of protamine-mediated acute pulmonary hypertension and right ventricular failure in the perioperative period of isolated coronary artery bypass grafting (CABG) operations.

Detection of Helicobacter pylori and Chlamydia pneumoniae DNA in human coronary arteries and evaluation of the results with serologic evidence of inflammation.

Objective: Atherosclerosis is pathologically similar to a chronic inflammatory response. Recent reports have suggested that Chlamydia pneumoniae (C. pneumoniae) and Helicobacter pylori (H.

Left atrial myxoma associated with acute myocardial infarction.

A 38-year-old male was admitted to our institution with left atrial myxoma complicated with acute myocardial infarction. The patient had no risk factor for coronary artery disease. A transthoracic echocardiographic study revealed the presence in the left atrium of an echogenic, mobile mass, compatible with myxoma.

Ectasia and severe atherosclerosis: relationships with chlamydia pneumoniae, helicobacterpylori, and inflammatory markers.

To date, there has been no convincing evidence for an association between Chlamydia pneumoniae or Helicobacter pylori and ectasia. In this case-control study, we have investigated the association of H. pylori and C.

Beneficial effect of the addition of nitroglycerin to the cardioplegic solution on lipid peroxidation during coronary artery bypass surgery.

The effects of the addition of a nitric oxide (NO) donor to the cardioplegic solution on reperfusion injury and lipid peroxidation (LPO) in coronary artery bypass grafting (CABG) are not known. Therefore, this work was conducted to determine the possible effects of nitroglycerin on LPO and reperfusion injury as a result of CABG. A prospective double-blind, placebo-controlled study was conducted in 30 consecutive patients with coronary artery disease who underwent CABG with cardiopulmonary bypass.

Role of endogenous adenosine in atrial fibrillation after coronary artery bypass graft.

Background: Atrial fibrillation (AF) is the most common complication following coronary artery bypass graft (CABG). The mechanism of AF after CABG is not well defined; however, it is suggested that endogenous adenosine, released in response to tissue hypoxia, may play a mechanistic role in these arrhythmias.

Hypothesis: The purpose of this study was to examine whether intravenous theophylline, via adenosine A1 receptor antagonism, would correct or modify new-onset early (<48 h post CABG) atrial fibrillation in patients post CABG, and thereby implicate endogenous adenosine as an inciting agent.

A case of mitral stenosis complicated with seronegative Brucella endocarditis.

Brucellosis is a multisystemic disease. The most common cause of death from the disease is endocarditis. The aortic valve is most commonly affected.

Surgically revascularized dual LAD.

Dual left anterior descending artery (or dual anterior interventricular artery, LAD) is a rare coronary artery anomaly. Dual but normally originated LAD has been usually reported to have no clinical significance. In this case report, we present a case of 75 year old male with anginal symptoms in whom coronary arteriography showed normally originated dual LAD with two branches of almost equal caliber.
