Oxidative DNA Damage and Arterial Hypertension in Light of Current ESC Guidelines.

A new insight into oxidative stress is based on oxidative deoxyribonucleic acid (DNA) damage. DNA is the pivotal biopolymer for life and health. Arterial hypertension (HT) is a globally common disease and a major risk factor for numerous cardiovascular (CV) conditions and non-cardiac complications, making it a significant health and socio-economic problem.

DNA damage and arterial hypertension. A systematic review and meta-analysis.

Oxidative DNA damage markers (8OHdG, comet assay, gammaH2AX) are becoming widely used in clinical cardiology research. To conduct this review of DNA damage in relation to hypertension in humans, we used databases (e.g.

Comet assay in evaluating deoxyribonucleic acid damage after out-of-hospital cardiac arrest.

Objective: This study aimed to investigate whether out-of-hospital cardiac arrest (OHCA) may induce severe DNA damage measured using comet assay in successfully resuscitated humans and to evaluate a short-term prognostic role.

Methods: In this prospective, controlled, blinded study (1/2013-1/2014), 41 patients (age, 63±14 years) successfully resuscitated from non traumatic OHCA and 10 healthy controls (age, 53±17 years) were enrolled. DNA damage [double-strand breaks (DSBs) and single-strand breaks (SSBs)] was measured using comet assay in peripheral lymphocytes sampled at admission.

Pharmaco-refractory chronic heart failure--the need for drug level tailored management.

Pharmacorefractory chronic heart failure is a serious world-wide problem of systolic dysfunction not improving despite evidence based chronic heart failure pharmacotherapy. With the aim to reverse the poor pharmacorefractory chronic heart failure prognosis, severe sophisticated technical therapeutic approaches (from cardiac resynchronization usually with implantable cardioverter-defibrillator to heart transplantation) have been clinically adopted and detached at least for the most eligible pharmacorefractory chronic heart failure patients. However, both significant limitations of these highly specialised therapeutic techniques (cost, uncertain individual effect, complication, adverse effect, waiting list) and the pharmacorefractory chronic heart failure hopelessness for unfit patients make the effort to stop the pharmacorefractory chronic heart failure genesis never ending longing.

Electrogastrography in experimental pigs: the influence of gastrointestinal injury induced by dextran sodium sulphate on porcine gastric erythromycin-stimulated myoelectric activity.

Objectives: Electrogastrography (EGG) is a non-invasive investigation of gastric myoelectrical activity. The aim of study was to evaluate the impact of erythromycin on EGG in gastrointestinal toxic injury induced by dextran sodium sulphate (DSS) in experimental pigs.

Methods: The experiments were carried out on 12 adult pigs (weighing 30-35 kg).

Five-year survival of patients after out-of-hospital cardiac arrest depending on age.

Patient's age belongs to the independent prognostic factors of patients after out-of-hospital cardiac arrest (OHCA). This study aimed to evaluate the influence of age on 5-year survival in professionally cardio-pulmonary resuscitated patients with "primary cardiac" etiology OHCA. In this analysis of prospective multi-centric study, from April 1, 2002 until August 31, 2004, a total of 560 patients were included (aged 16-97 years) from the East Bohemian region, for whom a professional cardio-pulmonary resuscitation for OHCA was attempted.

Bland-White-Garland syndrome in adults: sudden cardiac death as a first symptom and long-term follow-up after successful resuscitation and surgery.

Two cases (a 23-year-old man and a 33 year-old-woman) with Bland-White-Garland (BWG) syndrome (an anomalous origin of the left coronary artery from the pulmonary artery) are presented. Their first symptom was survived sudden cardiac death. Both patients underwent surgical repair.

Long-term prognosis after out-of-hospital cardiac arrest with/without ST elevation myocardial infarction.

Aim: To describe the 3-year survival of patients after out-of-hospital cardiac arrest (OHCA) taking into account the presence of ST-segment elevation myocardial infarction (STEMI) and evaluating prognostic factors associated with pre-hospital and hospital care.

Patient Group: Over a period of 29 months and with the aid of a questionnaire supplied to 24 rescue stations, we prospectively included 560 individuals (415 men; aged 16-97 years, median 68) for whom cardio-pulmonary resuscitation (CPR) for OHCA of confirmed cardiac etiology was attempted.

Results: Of 149 hospitalized individuals, 28.

The highest incidence of out-of-hospital cardiac arrest during a circadian period in survivors.

Unlabelled: Health care associated with cardiac arrest exhibits a significant economic burden, rather than effectiveness.

Hypothesis: The time of the out-of-hospital cardiac arrest (OHCA) onset during a diurnal period alters the survival chance. Professionally resuscitated patients for witnessed OHCA (n = 495) from the study were prospectively followed for 12 months.

Out-of-hospital cardiac arrests in patients with acute ST elevation myocardial infarctions in the East Bohemian region over the period 2002-2004.

Background: Early reperfusion by direct percutaneous coronary intervention (PCI) in patients with ST segment elevation acute myocardial infarctions (STEMI) with an out-of-hospital cardiac arrest (OHCA) reduces hospital and longterm mortality.

Aims: Evaluating the significance of direct PCI for the short-term (discharge from acute hospitalization) and 1-year survival in patients with acute STEMI after OHCA.

Methods: In this prospective study, from April 1, 2002 up to August 31, 2004, a total of 26 hospitalized individuals (22 men, 4 women, aged 35-79 years, median 58.

Characteristics and short-term survival of individuals with out-of-hospital cardiac arrests in the East Bohemian region.

Aim: We describe survival after admission to hospital from out-of-hospital cardiac arrest (OHCA) in the East Bohemian region, according to the Utstein Style guidelines and have identified the main diagnosis including in those who died and had an autopsy.

Patient Group: Over a period of 29 months we used a questionnaire supplied to 24 rescue stations, to identify 718 individuals (511 men and 207 women, aged 16-97 years) with confirmed cardiac arrest who were considered for resuscitation.

Results: Out of 560 patients in whom cardiopulmonary resuscitation for OHCA of confirmed cardiac aetiology was attempted, 350 patients (62.

Treatment of coronary bifurcation lesions by stent implantation only in parent vessel and angioplasty in sidebranch: immediate and long-term outcome.

The aim of this study was to evaluate the immediate and long-term outcome of intracoronary stent implantation for the treatment of bifurcation lesions. We treated 30 patients with bifurcation stenosis with the Bx Velocity stent implanted only in the parent vessel and with balloon angioplasty of the sidebranch. Angiographic success was 86.
