Hydrochlorothiazide became one of the most commonly prescribed first-line antihypertensive medication, though its use is often complicated with serious side-effects. A 66-year-old female patient with a history of hypertension had suffered a transient loss of consciousness, and referred to our cardiology unit with an ST-segment elevation and giant negative T-waves in V1-2 ECG leads, long QT-segment and elevated serum creatine-kinase (5392 U/L) and troponin I (4,357 ng/ml) levels. Acute myocardial infarction was not proven (later coronarography revealed preserved coronary circulation), but severe hyponatraemia and hypokalaemia was detected, explaining a possible symptomatic seizure, and which could be accounted for a 25 mg daily hydrochlorothiazide antihypertensive treatment and - as a precipitating insult - a one-week history of gastroenteritis...

OBJECTIVES: The authors aimed to evaluate the role of post-resuscitation electrocardiogram (ECG) in patients showing significant ST-segment changes on the initial ECG and to provide useful diagnostic indicators for physicians to determine in which out-of-hospital cardiac arrest (OHCA) patients brain computed tomography (CT) should be performed before emergency coronary angiography. BACKGROUND: The usefulness of immediate brain CT and ECG for all resuscitated patients with nontraumatic OHCA remains controversial...

Survivors of out-of-hospital cardiac arrest (OHCA) have high mortality and morbidity. An acute coronary event is the most common cause of sudden cardiac death. For this reason, coronary angiography is an important diagnostic and treatment strategy for patients with postcardiac arrest. This study aimed to identify the correlation between postreturn of spontaneous circulation (ROSC) on an electrocardiogram (ECG) and results of coronary angiography of OHCA survivors.We collected data from our OHCA registry from January 2010 to November 2014...

During 11 years period from January 2005 to December 2015 there were 18 adolescent and adult patients  who underwent transcatheter closure of PDA using PDA Amplatzer Duct Occluder (ADO). There were 9 cases with age of 14 to 18 years and 9 cases with age of more than 18 years where the oldest case was 46 years old. Two cases were male and 16 cases were female. Prior to procedures, clinical assessment, ECG, chest x-ray and transthoracic echocardiography (TTE) were performed to confirm the diagnosis of PDA. The procedures of device implantation was performed under conscious sedation in adults and using general anesthesia in adolescents...

Cardiopulmonary resuscitation (CPR) must be interrupted for reliable rhythm analysis in current automatic external defibrillators (AEDs) because of artifacts produced by chest compressions. However, interruptions in CPR adversely affect the restoration of spontaneous circulation (ROSC) and survival. Suppressing CPR artifacts by digital signal processing techniques is a promising method to enable rhythm analysis during chest compressions, which would eliminate CPR interruptions for rhythm analysis. Although numerous methods have been developed to suppress CPR artifacts, the accuracy of rhythm analysis is still inadequate due to the residual artifact components in the filtered signal...

A 58 years healthy old woman was admitted to the Emergency Department (ED) with cardiac arrest due to ventricular fibrillation (VF). Appropriate cardiopulmonary resuscitation (CPR), multiple DC shocks and oro-tracheal intubation (OTI) were effective to induce recovery of spontaneous circulation (ROSC). After ROSC was achieved, the electrocardiogram (ECG) showed an idio-ventricular rhythm with atrioventricular dissociation. A transcutaneous pacing was hence applied and the patient was administered with isoproterenol...

Cardiodynamicsgram (CDG) has emerged recently as a noninvasive spatiotemporal electrocardiographic method for subtle cardiac dynamics information analysis within electrocardiogram (ECG). This study sought to evaluate the clinical utility of CDG for early coronary artery disease (CAD) detection in suspected patients with CAD presenting with nondiagnostic ECGs. A total of 421 suspected patients with CAD presenting with nondiagnostic ECG were enrolled. Standard 12-lead ECG and CDG were performed simultaneously, 1 day before invasive coronary angiography...

BACKGROUND: Acetylcholine (ACh) was administered for 3min in the ENCORE study, while the Japanese Circulation Society guidelines recommended the 20s ACh injection as an ACh test. OBJECTIVES: We compared the ischemic findings between ACh administration for 3min and ACh injection for 20s in the same patients and in the same ACh doses without administration of nitrates in the left coronary artery. METHODS: We investigated 30 patients with ischemic heart disease (25 men, 67±10 years, ACh 50μg: 3, ACh 100μg: 9, ACh 200μg: 18) by the above two ACh injection procedures...

OBJECTIVE: With the demonstrated benefit of an early-invasive strategy for STEMI and VF/VT arrest patients, there is interest in assessing the potential benefit of early angiography for non-shockable (PEA/Asystole) arrest patients. We hypothesized that in cardiac arrest patients who obtain return of spontaneous circulation (ROSC) after a non-shockable initial rhythm and do not have STEMI the incidence of coronary intervention would be clinically insignificant (<5%). METHODS: Retrospective multicenter US clinical registry study of post-cardiac arrest patients at 18 hospitals between 1/00 and 5/14...

BACKGROUND: Alterations in autonomic nervous function are common in hemodialysis (HD) patients. Sympathetic as well as parasympathetic activation may be associated with immune and inflammatory responses. We intended to confirm a role of autonomous dysregulation for inflammation in HD patients. METHODS: 30 HD patients (including 15 diabetics) and 15 healthy controls were studied for heart rate variability (HRV) using 5 min ECG recordings. Heart rate variability was estimated by time-domain parameters (the standard deviation of the RR intervals (SDNN) and the percentage of pairs of adjacent RR intervals differing by >50 ms (pNN50)) and frequency-domain-analysis (high- and low-frequency variation of RR intervals, HF and LF)...

Spontaneous coronary artery dissection (SCAD) accounts approximately for 0.2% of cases of acute coronary syndrome. It is defined "spontaneous" in absence of any coronary wall damage. This disease affects primarily young women in good health, with no risk factors for coronary artery disease, especially during the postpartum period. Since the clinical presentation varies widely from no symptoms to typical angina and sudden cardiac death, SCAD incidence is underestimated.A 40-year-old woman, in the 8th week after delivery, was admitted to our emergency department because of acute chest pain, and a diagnosis of inferior and posterior non-ST-elevation myocardial infarction was made...

We hypothesized that stimulatory and superovulatory treatments, using equine chorionic gonadotropin (eCG), modulate the expression of genes related to insulin, cellular modelling and angiogenesis signaling pathways in the bovine corpus luteum (CL). Therefore, we investigated: 1-the effect of these treatments on circulating insulin and somatomedin C concentrations and on gene and protein expression of INSR, IGF1 and IGFR1, as well as other insulin signaling molecules; 2-the effects of eCG on gene and protein expression of INSR, IGF1, GLUT4 and NFKB1A in bovine luteal cells; and 3-the effect of stimulatory and superovulatory treatments on gene and protein expression of ANG, ANGPT1, NOS2, ADM, PRSS2, MMP9 and PLAU...

AIM OF THE STUDY: Predicting outcome of unconscious patients after successful resuscitation is challenging and better prognostic markers are highly needed. Ischemic heart disease is a common cause of out-of-hospital cardiac arrest (OHCA). Whether or not high-sensitivity troponin T (hs-TnT) is a prognostic marker among survivors of OHCA with both ischemic and non-ischemic aetiologies remains to be determined. We sought to evaluate the ability of hs-TnT to prognosticate all-cause mortality, death due to cardiovascular causes or multi-organ failure and death due to cerebral causes after OHCA...

BACKGROUND: Electrocardiogram (ECG) abnormalities following aneurysmal subarachnoid hemorrhage (SAH) have been well documented. Evidence suggests that ECG changes and cardiac dysfunction worsen outcome. Determining which patients are at most risk is unclear but important to ascertain. METHODS: We prospectively studied clinical markers, cardiac abnormalities, and clinical outcomes in 20 patients admitted within 48 hours of aneurysmal SAH. All patients had ECGs prior to surgical clipping, during the clipping surgery, and during the postoperative period...

INTRODUCTION: The American Heart Association recommends that post-arrest patients with evidence of ST elevation myocardial infarction (STEMI) on electrocardiogram (ECG) be emergently taken to the catheterization lab for percutaneous coronary intervention (PCI). However, recommendations regarding the utility of emergent PCI for patients without ST elevation are less specific. This review examined the literature on the utility of PCI in post-arrest patients without ST elevation compared to patients with STEMI...

During the periovulatory period, the cervix relaxes in response to changes in circulating concentrations of reproductive hormones. The present study investigated the role of gonadotrophins in cervical function by examining the expression of cyclooxygenase-2 (COX2) and COX2 mRNA and the concentration of hyaluronan (HA) in the cervix, after intracervical treatment with either FSH or LH. Eighteen ewes were assigned to four groups. They were then treated with commercial intravaginal progestagen sponges and eCG to synchronize their estrous cycles...

Antibody-drug conjugates (ADC) are designed to be stable in circulation and to release potent cytotoxic drugs intracellularly following antigen-specific binding, uptake and degradation in tumor cells. Efficient internalization and routing to lysosomes where proteolysis can take place is therefore essential. For many cell surface proteins and carbohydrate structures on tumor cells, however, the magnitude of these processes is insufficient to allow for an effective ADC approach. We hypothesized that we could overcome this limitation by enhancing lysosomal ADC delivery via a bispecific antibody (bsAb) approach, in which one binding domain would provide tumor specificity, whereas the other binding domain would facilitate targeting to the lysosomal compartment...
