E I Tarlovskaya, A A Odegova
BACKGROUND: Bronchial asthma (BA) is a serious problem. It was found that the frequency of arterial hypertension (AH) detection in patients with asthma is about 30 %. At patients practically all types of violations of a warm rhythm meet a bronkhoobstruktivny syndrome. Emergence of rather new preparations - If-blockers, opens new opportunities in correction of heart rate (HR) and a cardioprotection at a combination of AH and BA. AIM: To assess therapy diltiazem-retard and ivabradine on structurally functional changes of a cardiac muscle and HR at patients with AH in combination with BA...

The present methodology teaches the investigator how to measure and use the LAV as a surrogate of chronic elevations in Left Ventricular diastolic pressure through echocardiography, as well as to obtain measurements of the Aorta and PA diameter in mice. Mice older than 10 d of age can be analyzed using the present technique. The technique is composed of 3 main steps: set-up, image acquisition, and image analysis. The set-up step consists of getting the mouse anesthetized with 1% isoflurane, shaving it, and taping it in a supine position to a heated EKG board where the image acquisition will take place...

BACKGROUND: Device interrogation has become a standard part of the syncope evaluation for patients admitted with permanent pacemakers (PPM) or implantable cardiac defibrillators (ICD), although few studies have shown interrogation yields clinically useful data. The purpose of this study is to determine the diagnostic yield of device interrogation as well as other commonly performed tests in the workup of unexplained syncope in patients with previously implanted PPMs or ICDs. METHODS: We retrospectively reviewed records of 88 patients admitted to our medical center for syncope with previously implanted pacemakers between January 1, 2005 and January 1, 2015 using ICD-9 billing data...

BACKGROUND: Growth differentiation factor-15 (GDF-15), a cytokine associated with cardiovascular mortality, increases during chronic obstructive pulmonary disease (COPD) exacerbations, but any role in stable COPD is unknown. We tested associations between GDF-15 and subclinical coronary atherosclerosis, assessed by coronary artery calcium (CAC) score, in COPD subjects free of clinical cardiovascular disease (CVD). METHODS: Cross-sectional analysis of COPD participants (GOLD stages 2-4) in the COPDGene cohort without CVD at enrollment, using baseline CAC (from non-EKG-gated chest computed tomography) and plasma GDF-15 (by custom ELISA)...

The Brugada syndrome is a rare condition associated with increased risk of ventricular tachyarrhythmias and sudden cardiac death (SCD). The Brugada pattern on electrocardiogram (EKG) is known to be revealed by several precipitants including febrile illnesses. The appearance of a Brugada pattern on EKG with fever may indicate an elevated risk of arrhythmia or sudden cardiac death. We report a case in which the electrocardiographic abnormality of Brugada pattern induced by sepsis was initially misinterpreted as a ST-segment elevation myocardial infarction (STEMI)...

Coved-type ST-segment elevation in the right precordial leads are the characteristics of Brugada syndrome, an inherited arrhythmogenic ion channel disease, which could lead to ventricular arrhythmia and sudden death. Hypokalemia alone may induce Type 1 Brugada pattern electrocardiogram (EKG), and the association has rarely been reported. We describe a patient with hypokalemia 2.9 mmol/L and the appearance of new right bundle branch block pattern with coved ST-segment elevations with inverted T wave in leads V1-V2...

Despite the clinical efficacy of anthracycline agents such as doxorubicin, dose-limiting cardiac toxicities significantly limit their long-term use. Here, we present the case of a 33-year-old female patient with extensive metastatic ER+/PR+/HER2- mucinous adenocarcinoma of the breast, who was started on doxorubicin/cyclophosphamide therapy after progressing on paclitaxel and ovarian suppressor goserelin with aromatase inhibitor exemestane. The patient was comanaged by cardiology, who carefully monitored measures of cardiac function, including EKGs, serial echocardiograms, and profiling of lipids, troponin, and pro-BNP every 2 months...

The prognostic value of atrial fibrillation (AF) in heart failure with preserved ejection fraction (HFPEF) remains controversial. We sought to study the prognostic value of AF in a prospective cohort and to characterize the HFPEF patients with AF. KaRen was a prospective, multicenter, international, observational study intended to characterize HFPEF; 538 patients presenting with an acute decompensated cardiac failure and a left ventricular EF > 45% were included. EKG and echocardiogram performed 4-8 week following the index hospitalization were analyzed in core centers...

Reduced cerebrovascular reactivity (CVR) was found in patients with recent lacunar infarct. However, its mechanisms were controversial. The breath holding maneuver as vasodilatory stimulus is clinically useful for an estimation of cerebrovasomotor reactivity in well co-operative patients. Patients with lacunar infarct have no higher cortical dysfunction and remain well co-operation. The breath holding maneuver is feasible and safe to perform in patients with lacunar infarct. Autonomic nervous system regulates systemic vascular activity...
