INTRODUCTION: The standard treatment of sinus node dysfunction (SND) is the pacemaker implantation, and the ideal methodology for the management of atrial fibrillation (AF) is rhythm control, but this is sometimes very hard to accomplish. For such actions, complete isolation of all pulmonary veins (PVI) is currently widely accepted as the best endpoint. CASE PRESENTATION: In this case, we report a female patient, 81 years old, with controlled hypertension, without coronary artery disease, bearer of bilateral knee replacement, and dual chamber pacemaker implanted 1...

Hypertension (HTN) is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease (CAD), stroke, peripheral artery disease and chronic renal failure. Hypertensive heart disease can manifest as many types of cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in HTN patients, especially in those with left ventricular hypertrophy (LVH), CAD, or HF. In addition, high doses of thiazide diuretics commonly used to treat HTN, may result in electrolyte abnormalities (e...

Background: Short-term heart rate variability (HRV) is most commonly attributed to physiologic vagal tone modulation. However, with aging and cardiovascular disease, the emergence of high short-term HRV, consistent with the breakdown of the neuroautonomic-electrophysiologic control system, may confound traditional HRV analysis. An apparent dynamical signature of such anomalous short-term HRV is frequent changes in heart rate acceleration sign, defined here as heart rate fragmentation. Objective: The aims were to: (1) introduce a set of metrics designed to probe the degree of sinus rhythm fragmentation; (2) test the hypothesis that the degree of fragmentation of heartbeat time series increases with the participants' age in a group of healthy subjects; (3) test the hypothesis that the heartbeat time series from patients with advanced coronary artery disease (CAD) are more fragmented than those from healthy subjects; and (4) compare the performance of the new fragmentation metrics with standard time and frequency domain measures of short-term HRV...

In stress-induced takotsubo cardiomyopathy (TC) high levels of catecholamines, including epinephrine, may be detected in blood. On the other hand, administration of exogenous epinephrine may occasionally result in TC. A CASE REPORT: The authors describe a case of a 58-year-old, otherwise healthy female, with TC which occurred after intravenous injection of 1 mg of epinephrine against cardiac arrest provoked by pneumoperitoneum performed before planned laparoscopic cholecystectomy. She was admitted 3 days earlier due to biliary colic following a dietary mistake...

Postoperative atrial fibrillation (AF) occurs frequently after cardiac surgery and contributes significantly to mortality. Transforming growth factor-beta (TGF-β) is associated with postoperative AF after coronary artery bypass grafting and valve surgery. We performed a prospective study to evaluate the role of TGF-β as a predictor of AF after myectomy. A total of 109 consecutive obstructive hypertrophic cardiomyopathy patients without previous AF who underwent myectomy were identified. We measured plasma TGF-β levels before surgery, monitored heart rhythm until discharge, and followed patients for a mean of 36 ± 10 months...

Cardiac arrhythmias confer a considerable burden of morbidity and mortality in industrialized countries. Although coronary artery disease and heart failure are the prevalent causes of cardiac arrest, in 5-15% of patients, structural abnormalities at autopsy are absent. In a proportion of these patients, mutations in genes encoding cardiac ion channels are documented (inherited channelopathies), but, to date, the molecular autopsy is negative in nearly 70% of patients. Emerging evidence indicates that autoimmunity is involved in the pathogenesis of cardiac arrhythmias...

Challenging times are here for cardiac surgical and anesthesia team. The interventional cardiologist seem to have closed the flow of 'good cases' coming up for any of the surgery,; successful percutaneous interventions seem to be offering reasonable results in these patients, who therefore do not knock on the doors of the surgeons any more . It is a common experience among the cardiac anesthesiologists and surgeons that the type of the cases that come by now are high risk. That may be presence of comorbidities, ongoing medical therapies, unstable angina, uncontrolled heart failure and rhythm disturbances; and in patients with ischemic heart disease, the target coronaries are far from ideal...

OBJECTIVE: Predicting the outcome of out-of-hospital cardiac arrest (OHCA) patients is crucial. We examined hospital characteristics and parameters of emergency medical service (including scene time interval and direct ambulance delivery to intensive heart hospitals) as survival or outcome predictors. STUDY DESIGN: Data from 546 consecutive OHCA shockable patients treated between January 2012 and December 2015 in Taoyuan City (Taiwan, ROC) were collected. In addition to demographic data, location of arrest, initial rhythm, availability of a hospital with or without 24/7 percutaneous coronary intervention (PCI), emergency medical service (EMS) time, provision of cardiopulmonary resuscitation by a bystander, presence of a witness at collapse, and level of life support were analysed...

BACKGROUND: Impaired cardiac autonomic function has been linked to adverse outcomes in patients with acute coronary syndromes (ACS) but is not included in clinical risk models. This is the first study to investigate whether point-of-care testing of cardiac autonomic function by means of short-term deceleration capacity (DC) of heart rate improves risk assessment in patients with suspected ACS. METHODS: 1821 patients with suspected ACS were prospectively enrolled if they were older than 17 years and in sinus rhythm...

Diagnosis of dilation (D) cardiomyopathy (CMP) requires exclusion not only of inflammatory and genetically determined forms but also of some rare diseases. This 51 year old patient with history of moderate arterial hypertension approached a cardiologist because of new onset atrial fibrillation and dyspnea. Echocardiography detected dilation of all cardiac chambers with relatively preserved ejection fraction, causing suspicion of DCMP. Among conditions excluded were coronary atherosclerosis, congenital heart defect with left to right shunt, primary pulmonary hypertension, pulmonary embolism, hypertensive heart, tachycardia induced CMP, arrhythmogenic right ventricular dysplasia, noncompaction myocardium...

Biomarkers are important prognostic tools in various cardiovascular conditions, including coronary artery disease and heart failure. Although their utility in cardiac electrophysiology (EP) is less established, biomarkers may guide EP clinical practice by identifying patients at risk for developing arrhythmias and their complications, in addition to augmenting therapeutic decisions by targeting appropriate pharmacologic and interventional therapies to patients who may benefit most. In this review, we focus on the prognostic role of high-sensitivity cardiac troponin (hs-cTn) assays-which detect subclinical cardiac myocyte damage-in cardiac arrhythmias and their sequelae...

Background and Objectives Although the frequency of cardiovascular events, especially the end manifestation of myocardial infarction, has decreased in recent years, cardiovascular disease continues to be one of the most frequent illnesses. Also it is known that the cardiac system sustains more stress at high altitudes than it does at intermediate altitudes. This leads to the question if young alpinists should undergo cardiac evaluation before setting out for a trip to the Himalayas or the Andes Mountains...

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall with minimal periinfarct ischemia. Computed tomography coronary angiogram revealed an anomalous left main coronary artery arising from the main pulmonary artery...

Cardiac involvements are common in patients with Dermatomyositis, most of which are not severe enough to present definite or readily observable symptoms. However, Cardiovascular (CVS) manifestations constitute a major cause of death in these patients. The most frequently reported clinically evident of CVS manifestations in-patient of dermatomyositis are Congestive Heart Failure (CHF), conduction aberrations, that may predispose to complete heart block and coronary artery disease. The principal pathophysiological mechanisms that may produce these cardiac manifestations involve coronary artery disease as well as small vessels vasculitis of the myocardium...

We report the case of a 82-year-old woman who was admitted to our institution with acute chest pain, nausea, and vomiting. Because of atrial fibrillation with intermittent bradycardia, a single-chamber pacemaker was implanted 4 years ago. The initial 12-lead ECG showed atrial fibrillation with a heart rate of 70 bpm, narrow QRS, and T‑wave inversions in the inferolateral leads. Coronary artery disease was excluded by immediate cardiac catheterization. A subsequent ECG three hours later showed a ventricular paced rhythm...

BACKGROUND: Sudden cardiac death caused by coronary artery disease (CAD-SCD) is the most frequent cause of SCD in persons <50years. The aim of this study was to examine differences in clinical characteristics and autopsy findings of the heart among 18-35 and 36-49year old CAD-SCD cases. METHODS: We have previously identified all sudden cardiac deaths in Denmark through review of death certificates and autopsy reports including all deaths between 2000 and 2006 in individuals aged 18-35years and all deaths between 2007 and 2009 in individuals aged 18-49years...
