Interleukin-2 as a predictor of early postoperative atrial fibrillation after cardiopulmonary bypass graft (CABG).

Recently, inflammation has been considered as a risk factor of postoperative atrial fibrillation (PAF). The main purpose of this study was to estimate the connections between occurrence of PAF and cytokine release. Thirty-three patients who qualified for cardiopulmonary bypass graft (CABG) were included in the study.

Inflammatory response of coronary artery disease postmenopausal women is associated with the IVS1-397T > C estrogen receptor alpha polymorphism.

We analyzed the relationship between the IVS1-397T > C polymorphism of estrogen receptor alpha gene and inflammatory response of eighty postmenopausal women with an established coronary artery disease (CAD). We found that the IVS1-397T allele carriers exhibited an enhanced inflammatory response in vivo and in vitro. These patients had a higher number of total monocytes and their CD14(+)CD16(+) inflammatory subset in relation to CC homozygotes.

NK cell compartment in patients with coronary heart disease.

Background: Viral and bacterial infections have been considered as a risk factor for Coronary Heart Disease (CHD). NK cells, as a first line of defense against those infections, may play a role in CHD development. Thus, the main aim of our study was to determine NK cell compartment in patients with CHD undergoing coronary artery by-pass grafting.

Interleukin 6 polymorphism corresponds to the number of severely stenosed coronary arteries.

IL6 gene promoter polymorphisms may influence the outcome of cardiovascular diseases. The aim of our study was to find out whether the -174G>C polymorphism, as well as the IL6 secretory profile, may be linked to the number of severely (> or = 75%) occluded coronary arteries in patients with advanced coronary heart disease (CHD). Three hundred and twenty patients awaiting elective coronary artery bypass grafting were enrolled into the study.

Long-term prognosis after coronary bypass surgery depends on interleukin 6 polymorphism and past acute infections.

We were seeking for a mutual link between the -174G>C IL6 promoter polymorphism, history of the past acute respiratory infections and the long-term post-coronary artery bypass grafting (CABG) major adverse cardiovascular events (MACE) incidence. Two hundred thirty seven post-CABG patients have been followed up for a median period of 36 months. We found that past acute infections, influenza-like illness and lack of vaccination against influenza confer a significant risk of the post-CABG MACE incidence in the -174G allele carrying patients.

High serum interleukin-18 concentrations in patients with coronary artery disease and type 2 diabetes mellitus.

Aims: The aim of our study was to analyse the serum level of interleukin 18 (IL-18) in coronary artery disease (CAD) patients with type 2 diabetes mellitus (DM), and to relate this to clinical findings.

Methods: The IL-18 level was measured by ELISA in serum samples from 130 CAD patients prior to their first, elective, coronary artery bypass surgery. Forty-three of them had been diabetic for several years.

Stroke volume variability and heart rate power spectrum in relation to posture changes in healthy subjects.

Background: Power spectrum analysis of heart rate variability (HRV) can be used to assess the state of sympathovagal balance-modulating sinus node activity. Stroke volume variability (SVV) probably reflects the dynamics of physiological control mechanisms over time.

Material/methods: Power spectrum HRV and SVV were simultaneously measured in 44 healthy men.

[Intraoperative thermography--temperature range on the heart surface during cold cardioplegia].

The paper presents the temperature analysis of the myocardial surface at the cohort of 11 patients with coronary artery disease, who underwent coronary artery bypass grafting with cardiopulmonary bypass. Left and right ventricle temperature changes were registered with Agema Thermovision 900 SW/TE system during cold cardioplegia infusion. Cardioplegia was delivered by the coronary sinus and by the aortic root.
