OBJECTIVES: An acute coronary occlusion and its possible subsequent complications is one of the most common causes of death. One such complication is ventricular fibrillation (VF) due to myocardial ischemia. The severity of ischemia is related to the amount of coronary arterial collateral flow. In dog studies collateral flow has also been shown to be associated with QRS prolongation. The aim of this study was to investigate whether ischemic QRS prolongation (IQP) is associated with impending VF in an experimental acute ischemia dog model...

OBJECTIVES: A careful selection of reference samples in studies on the pathogenesis of thoracic ascending aorta (TAA) dilation is crucial for reliability, consistency and reproducibility of experimental results. Several studies include control TAA samples from heart donors. Others include samples harvested during coronary artery bypass graft (CABG) procedures or a mix of samples from heart donors and CABG patients. We verified the equivalence/homogeneity of TAA samples from heart donors and CABG patients in terms of basal gene expression and thus their reliability as reference groups in aortopathy studies...

Juraj Sokol, Frantisek Nehaj, Jela Ivankova, Michal Mokan, Marian Mokan, Jan Stasko
OBJECTIVE: Dabigatran is a direct thrombin inhibitor. As the main adverse event is bleeding, it is relevant whether dabigatran has additional effects on platelet function. If so, it could affect the bleeding risk. We aimed to assess in vitro aggregation in patients with atrial fibrillation (AF) receiving dabigatran. DESIGN: We evaluated 32 AF patients treated with dabigatran (study group) and 18 non-anticoagulated non-AF blood donors (control group). We assessed light transmittance platelet aggregation (LTA) with 100 nmol/L γ-thrombin in both groups...

Oleg E Osadchii
OBJECTIVES: In normal conditions, sudden heart rate acceleration provokes a rapid reduction in ventricular action potential duration (APD). The protracted APD rate adaptation favors early afterdepolarizations and precipitates arrhythmia. Nevertheless, it is uncertain as to whether the rate-dependent changes of ventricular repolarization can be adversely modified by arrhythmogenic drugs (quinidine and procainamide) and hypokalemia, in comparison to the agents with safe therapeutic profile, such as lidocaine...

OBJECTIVES: Left ventricular ejection fraction (EF) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are important surrogate markers of cardiac function and wall stress. Randomized trials of heart failure (HF) have shown improvements in survival in patients with reduced EF (<40%, HFrEF) but not with preserved EF (≥50%, HFpEF) or mid-range EF (40-49%, HFmrEF). Limited information is available on the trajectory of EF in contemporary heart failure management programs (HFMPs)...

OBJECTIVE: Endothelial function, including the nitric oxide (NO)-pathway, has previously been extensively investigated in heart failure (HF). In contrast, studies are lacking on the NO pathway after heart transplantation (HT). We therefore investigated substances in the NO pathway prior to and after HT in relation to hemodynamic parameters. DESIGN: 12 patients (median age 50.0 yrs, 2 females), heart transplanted between June 2012 and February 2014, evaluated at our hemodynamic lab, at rest, prior to HT, as well as four weeks and six months after HT were included...

OBJECTIVE: Circulating levels of endostatin are elevated in many underlying conditions leading to heart failure such as hypertension, diabetes, chronic kidney disease and ischemic heart disease. Yet, the association between endostatin and the incidence of heart failure has not been reported previously in the community. DESIGN: We investigated the longitudinal association between serum endostatin levels and incident heart failure in two community-based cohorts of elderly: Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS, n = 966; mean age 70 years, 51% women, 81 events, mean follow-up 10 years) and Uppsala Longitudinal Study of Adult Men (ULSAM, n = 747 men; mean age 78 years, 98 heart failure events, mean follow-up 8 years)...

OBJECTIVES: With a steadily growing number of patients with non-valvular atrial fibrillation, anticoagulation use increases. Anticoagulation therapy is associated with increased risk of serious bleeding and an increased complexity in management of patients in need for urgent surgery. We wanted to assess the magnitude of this challenge as well as review current and potential future clinical management strategies. DESIGN: A review of the literature on the magnitude of patients using antigoaculants in potential need for acute restoration of hemostasis was conducted, as well as current status of reversal agents for non-vitamin K antagonist oral anticoagulants (NOACs)...

OBJECTIVE: Temporal variations in the occurrence of out-of-hospital cardiac arrest (OHCA) have been shown. Most previous studies have in common that they include individuals whom have received cardiopulmonary resuscitation (CPR) and thus excluding a great number of all the actual cases of OHCA when conducting a study. Therefore the aim of this study was to describe temporal variations of OHCA, regardless of whether CPR was performed or not. DESIGN: All individuals aged 25-74 years in northern Sweden, 1989-2009, who suffered an out-of-hospital cardiac arrest with validated myocardial infarction aetiology (OHCA-V), regardless of whether CPR was performed or not, were included in this study, which resulted in 3357 individuals...
