The patient was an-85-year-old man with hypertension and hyperlipidemia. The patient had a history of faintness on standing. He visited our hospital after experiencing chest oppression and pre-syncope in 2015. Brain magnetic resonance imaging and echocardiography did not detect any structural brain or heart disease. Ischemic heart disease was suspected based on the myocardial scintigraphy findings, but coronary angiography revealed no unusual findings. Holter electrocardiography did not reveal the reason for his symptoms...

Advances in the field of defibrillation have brought to practice different types of devices that include the transvenous implantable cardioverter-defibrillator (ICD) with or without cardiac resynchronization therapy, the subcutaneous ICD (S-ICD), and the wearable cardioverter-defibrillator. To ensure optimal use of these devices and to achieve best patient outcomes, clinicians need to understand how these devices work, learn the characteristics of patients who qualify them for one type of device versus another, and recognize the remaining gaps in knowledge surrounding these devices...

Premature ventricular complexes are very common, appearing most frequently in patients with hypertension, obesity, sleep apnea, and structural heart disease. Sympathetic hyperactivity plays a critical role in the development, maintenance, and aggravation of ventricular arrhythmias. Recently, Armaganijan et al reported the relevance of sympathetic activation in patients with ventricular arrhythmias and suggested a potential role for catheter-based renal sympathetic denervation in reducing the arrhythmic burden...

Several types of cardiovascular complications can occur during treatment with targeted therapies: heart failure, QTc lengthening, arterial and venous thrombosis. A clinical examination, ECG and cardiac ultrasound are essential before starting treatment with targeted therapy. Patients with no medical history, who are asymptomatic with a normal ECG and a left ventricular ejection fraction (LVEF) greater than 50% can begin molecular targeted therapy (MTT). Patients must be assessed by a cardiologist before the introduction of MTT if they have a history of ischemic or valvular heart disease, heart failure, atrial fibrillation, stroke, transient ischemic attack, or ECG anomalies (Q wave, supraventricular arrhythmia, QT greater than 500ms), or LVEF less than 50%...

In the present article, we review publications from the previous year in the following 3 areas: clinical cardiology, geriatric cardiology, and heart failure and transplantation. Among the new developments in clinical cardiology are several contributions from Spanish groups on tricuspid and aortic regurgitation, developments in atrial fibrillation, syncope, and the clinical characteristics of heart disease, as well as various studies on familial heart disease and chronic ischemic heart disease. In geriatric cardiology, the most relevant studies published in 2014 involve heart failure, degenerative aortic stenosis, and data on atrial fibrillation in the geriatric population...

Programmed ventricular stimulation was used extensively in the 1970s and has markedly improved our knowledge about the electrophysiological mechanisms of reentrant ventricular arrhythmias. In numerous observational but also randomized studies, it was shown that the induction of a monomorphic ventricular tachycardia by programmed ventricular stimulation was associated with an increased risk of spontaneous ventricular tachycardia or even sudden cardiac death in the future. Despite these results and the guidelines of ACC and ESC recommending the use of programmed ventricular stimulation in patients with recent and remote myocardial infarction, reduced ejection fraction, and complex ventricular arrhythmias or syncope, programmed ventricular stimulation is only seldom used and does not play a relevant role in clinical practice today...

In patients with stable chest pain, coronary CT angiography (CCTA) has demonstrated high accuracy in excluding coronary artery disease and CCTA findings carry prognostic significance for the occurrence of future cardiovascular events. Increasingly, CCTA has been adopted as a triage tool in patients with acute chest pain. In specific clinical scenarios, CCTA further represents a useful tool to exclude an ischemic etiology in patients with cardiac arrhythmias or newly diagnosed heart failure. Several novel techniques are currently being investigated which may extend the ability of CCTA to characterize and quantify coronary artery plaque and assess the hemodynamic significance of stenosis...

INTRODUCTION: Atrial fibrillation (AF) is the most common form of arrhythmia in humans and is associated with substantial morbidity and mortality. Obesity and diabetes have been linked to myocardial lipotoxicity - a condition where the heart accumulates and produces toxic lipid species. We hypothesized that obesity and diabetes were involved in the pathophysiology of AF by means of promoting a lipotoxic phenotype in atrial muscle, and that AF predicts mortality in cardiac care patients...

This paper introduces a scalable "climate health justice" model for assessing and projecting incidence, treatment costs, and sociospatial disparities for diseases with well-documented climate change linkages. The model is designed to employ low-cost secondary data, and it is rooted in a perspective that merges normative environmental justice concerns with theoretical grounding in health inequalities. Since the model employs International Classification of Diseases, Ninth Revision Clinical Modification (ICD-9-CM) disease codes, it is transferable to other contexts, appropriate for use across spatial scales, and suitable for comparative analyses...

There are a number of hereditary and non-hereditary central nervous system (CNS) disorders, which directly or indirectly affect the heart (brain-heart disorders). The most well-known of these CNS-disorders are epilepsy, stroke, subarachanoid bleeding, bacterial meningitis, and head injury. In addition, a number of hereditary and non-hereditary neurodegenerative disorders may impair cardiac functions. Affection of the heart may manifest as arrhythmias, cardiomyopathy, or autonomic dysfunction. Rarer cardiac complications of CNS disorders include heart failure, systolic or diastolic dysfunction, myocardial infarction, arterial hypertension, or pulmonary hypertension...

Nonischemic myocardial disease or cardiomyopathy can present as arrhythmia, palpitations, heart failure, dyspnea, lower extremity edema, ascites, syncope, and/or chest discomfort and can be classified as either systolic, diastolic, or a combination of both. Echocardiography is the mainstay of evaluating left ventricular function. However, cardiac magnetic resonance imaging (MRI) is now considered the reference standard imaging technique to assess myocardial anatomy, function, and viability. Advanced MRI techniques with delayed myocardial enhancement, especially, can provide information beyond echocardiography for tissue characterization in CM and can assist in determining specific etiology or in narrowing the differential...

Syncope is caused by cerebral hypoperfusion. Most fainting is simply vasovagal syncope and the challenge lies in identifying the few patients who have potentially life-threatening causes of syncope. Syncope patients constitute 1%-2% of emergency department visits and approximately 30%-50% are admitted to hospital. The known causes are vasovagal syncope (50%), and orthostatic hypotension and cardiac syncope (7% each). Structural heart disease is noted in 3%. The 30-day mortality is only 0.7%, and the 30-day adverse outcome is 4...

Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by a dynamic left ventricular outlet tract (LVOT) obstruction, which may be exacerbated by reduced preload and Valsalva. Laparoscopic adjustable gastric band (LAGB) placement is a restrictive bariatric procedure which may be complicated by recurrent vomiting and Valsalva. Pre-operative cardiac evaluation of patients scheduled for LAGB usually focuses on ischemic heart disease. Reported here is the case of a 64-year-old female admitted for evaluation of recurrent pre-syncopal episodes...
