BACKGROUND: Symptomatic non-obstructive coronary artery disease is a growing clinical dilemma for which contemporary testing is proving to be of limited clinical utility. New methods are needed to identify cardiac dysfunction. METHODS AND RESULTS: This is a prospective observational cohort study conducted from December 2013 to August 2015 in two outpatient cardiology clinics (symptomatic cohort) and 24 outpatient practices throughout the US (healthy cohort) with centralized methodology and monitoring to compare heart-rate responses during cardiopulmonary exercise testing (CPET)...

Exercise induces arterial flow patterns that promote functional and structural adaptations, improving functional capacity and reducing cardiovascular risk. While heat is produced by exercise, local and whole-body passive heating have recently been shown to generate favorable flow profiles and associated vascular adaptations in the upper limb. Flow responses to acute heating in the lower limbs have not yet been assessed, or directly compared to exercise, and other cardiovascular effects of lower-limb heating have not been fully characterized...

BACKGROUND: Prehypertension has a high risk of progression to hypertension, and intensive lifestyle modification including regular exercise is recommended for the management of prehypertensive individuals. However, data on the association between exercise capacity and hypertension status are limited. Therefore, we aimed 1) to define the characteristics of prehypertension, focusing on metabolic aspects and exercise capacity, and 2) to elucidate determinants of exercise capacity in healthy individuals without hypertension...

BACKGROUND Irisin, an exercise-induced myokine, is closely correlated with obesity and body mass index. Obesity is one risk factor of coronary artery disease (CAD). Therefore, the present study aimed to determine if serum irisin concentrations are correlated with the presence and severity of CAD. MATERIAL AND METHODS Serum irisin concentrations were determined in 350 patients with CAD and in 214 healthy subjects. The severity of CAD was assessed by coronary atherosclerosis index (CAI). RESULTS Serum irisin concentrations were significantly lower in CAD patients compared with healthy controls...

Paul Khairy
PURPOSE OF REVIEW: The literature on sudden death in transposition of the great arteries (D-TGA) with atrial switch surgery is reviewed and a pathophysiological mechanism is proposed. RECENT FINDINGS: Over 80% of sudden deaths in patients with D-TGA and Mustard or Senning baffles occur during exercise. Factors most consistently associated with ventricular arrhythmias and sudden death include heart failure parameters and atrial arrhythmias. Atrial arrhythmias have been observed to trigger malignant ventricular arrhythmias...

Aim: Advanced atherosclerosis increases inflammation and stroke risk in the cerebral vasculature. Exercise is known to improve cardio-metabolic profiles when associated with a caloric restriction, but it remains debated whether it is still beneficial without the dietary control. The aim of this study was to determine both the peripheral and central effects of exercise training combined with a cholesterol-rich diet given ad libitum in old ApoE(-/-) mice. Methods: Forty-five-weeks old obese ApoE(-/-) mice fed with a high cholesterol diet ad libitum were divided into Exercise-trained (EX; running wheel free access) and Sedentary (SED) groups...

OBJECTIVE: After stent or bypass surgery blood pressure (BP) can go up for multiple reasons among which are: stress and tense of the patient unsure about the future, the pain of the cut and because some of the blood pressure medication, which the patient was receiving preoperatively may get withdrawn post operatively, thereby leading to shooting up the BP. In certain patients, BP actually comes down after surgery and returns back to the pre-operative levels 4 to 6 weeks down the track...

Although moderate levels of exercise reduce cardiovascular morbidity and mortality in the general population, recent data have questioned whether higher doses of physical activity are associated with diminished health benefits and adverse outcomes. This review focuses on several issues at the center of this controversy including epidemiologic data describing mortality trends in those who engage in high levels of physical activity and recent observational data suggesting adverse cardiovascular outcomes among long-term endurance athletes...

Peripheral arterial disease (PAD) is the result of atherosclerosis in the lower limb arteries, which can give rise to intermittent claudication (IC), limb ulceration, infections, and, in some circumstances, amputation. As a result of PAD, patients are frequently limited in both walking duration and speed. These ambulatory deficits impact both functional capacity and quality of life. The prevalence of PAD is increasing, and patients with this diagnosis have high cardiovascular morbidity and mortality. A comprehensive approach is required to improve outcomes in patients with PAD and include tobacco cessation, pharmacologic management of metabolic fitness, risk-factor modification, and exercise training...

Hypercholesterolemia is common in psittacines, and Amazon parrots ( Amazona spp.) are particularly susceptible. Associations have been demonstrated between naturally occurring and experimentally induced hypercholesterolemia and atherosclerosis in psittacines. Daily exercise improves lipid metabolism in humans and other mammals, as well as pigeons and chickens, under varying experimental conditions. Hispaniolan Amazon parrots ( Amazona ventralis ) with naturally occurring hypercholesterolemia (343-576 mg/dl) were divided into two groups...

BACKGROUND: Rheumatoid arthritis (RA) is a condition associated with accelerated progression of atherosclerosis in affected individuals. Myocardial assessment using exercise testing in such patients, however, is often difficult to perform. Our objective was to determine the factors associated with severe coronary stenosis using computed tomography (CT) angiography of the coronary arteries in asymptomatic patients with RA. METHODS: Forty-four women with RA were examined using CT angiography to detect atherosclerotic involvement and significant coronary stenosis (>50 %)...

A 48-year-old woman with 40 years of intermittent squeezing chest pain presented with worsening symptoms. Results of an ambulatory electrocardiogram, echocardiogram, and exercise treadmill were unremarkable. Persistent symptoms prompted a computed tomography coronary angiogram (CTCA) that revealed mid-left anterior descending artery myocardial bridging (MB) that was not physiologically significant by exercise single-photon emission CT. Conservative treatment was pursued. Anatomic MB is prevalent in a large proportion of the general population and are increasingly identified by CTCA...

Carotid artery atherosclerosis (CAA) represents a significant form of atherosclerosis with stroke as a major consequence. Whether it is a unique form of atherosclerosis is not established. However, this is not of major clinical relevance as no specific preventive measures over and above the established ones for cardiovascular risk are well established. Major risk factors for CAA are elevated low-density lipoprotein cholesterol (LDL-C), diabetes mellitus, tobacco use, hypertension, and increased inflammation...
