Yong Hwan Kim, Wi-Young So
Cardiac rehabilitation (CR) is a structured program for the prevention of secondary cardiovascular disease (CVD) and related diseases, such as hypertension, diabetes, and obesity. This study aimed to investigate whether there are gender differences after 9 months of home-based cardiac rehabilitation program in post-percutaneous coronary intervention patients. A total of 114 (58.29 ± 10.33 years) men and 30 (60.90 ± 9.32 years) women were enrolled in the CR program. The program included three visits: initial, 4th month (follow-up), and 9th month (final) visits at a CR center...

BACKGROUND: Periodic breathing (PB) is often observed in patients with HF at rest, with sleep and during exercise. However, mechanisms underlying abnormal ventilatory control are not entirely established. METHODS: Eleven subjects with HF (10M, age=69±12yr) and 12 age-matched controls (8M, age=65±9yr) participated in the study. PB was defined as a peak in the 0.003-0.04Hz frequency range of the flow signal during 6-minutes of awake resting breathing. Thoracic blood volumes (Vt , thorax; Vh , heart; Vp , pulmonary), mean transit times (MTT) and extravascular lung water (EVLW) were quantified using computed tomography...

AIMS: The New York Heart Association (NYHA) classification is frequently used in the management of heart failure but may be limited by patient and physician subjectivity. Cardiopulmonary exercise testing (CPET) provides a potentially more objective measurement of functional status. We aim to study the correlation between NYHA classification and peak oxygen consumption (pVO2 ) on Cardiopulmonary Exercise Testing (CPET) within and across published studies. METHODS AND RESULTS: A systematic literature review on all studies reporting both NYHA class and CPET data was performed, and pVO2 from CPET was correlated to reported NYHA class within and across eligible studies...

E487K point mutation of aldehyde dehydrogenase (ALDH) 2 (ALDH2*2) in East Asians intrinsically lowers ALDH2 activity. ALDH2*2 is associated with diabetic cardiomyopathy. Diabetic patients exhibit heart failure of preserved ejection fraction (HFpEF) i.e. while the systolic heart function is preserved in them, they may exhibit diastolic dysfunction, implying a jeopardized myocardial health. Currently, it is challenging to detect cardiac functional deterioration in diabetic mice. Stress echocardiography (echo) in the clinical set-up is a procedure used to measure cardiac reserve and impaired cardiac function in coronary artery diseases...

BACKGROUND: Electrical dyssynchrony and prolonged QRS duration are common in patients with repaired tetralogy of Fallot (ToF). It has been linked to increased risk of sudden cardiac death and right ventricular (RV) dysfunction. We investigated myocardial dyssynchrony using cardiac magnetic resonance imaging (CMR) and feature tracking analysis (FT) in this setting and compared it to myocardial deformation, conventional parameters of ventricular dysfunction and clinical parameters. METHODS AND RESULTS: Patients underwent standardized CMR investigations as part of a nationwide study...

Reduction in inspiratory capacity (IC) during exercise has been reported in chronic heart failure (CHF). Since inspiratory muscle dysfunction may be present to a variable degree, the assumption that IC reduction during exercise represents an increase in end-expiratory lung volume must be made with caution. This interpretation is flawed if patients develop dynamic inspiratory muscle strength reduction, i.e., progressively lower esophageal (Pes) pressures as the IC maneuvers are repeated. Sixteen CHF patients and 9 age-matched controls performed an incremental exercise test with serial IC and respiratory pressure measurements...

INTRODUCTION: Precooling with ice slurry ingestion attenuates the increase in rectal temperature (Tre) during subsequent running and cycling. It remains unclear how this cooling method affects physiological strain during work while wearing protective garments. This study investigated the effect of ice slurry ingestion on physiological strain during work in hot conditions while wearing firefighter protective clothing. METHODS: In three counterbalanced trials, eight men (mean ± SD; age = 21 ± 2 yr, height = 179...

RATIONALE: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare but potentially lethal inherited arrhythmia syndrome induced by adrenergic stress. Due to the atypical clinical manifestations in early age, limited recognition and experience of pediatric cardiologists, and low awareness of the significance of genetic diagnosis in some underdeveloped areas in China, a delayed or missed diagnosis of CPVT in children is common and concerning. PATIENT CONCERNS: A 9-year and 3-month male child with recurrent exercise-induced syncope accompanied by convulsion was initially misdiagnosed as epilepsy since the first manifestation at the age of 3 years...

BACKGROUND: A growing number of wearable devices claim to provide accurate, cheap and easily applicable heart rate variability (HRV) indices. This is mainly accomplished by using wearable photoplethysmography (PPG) and/or electrocardiography (ECG), through simple and non-invasive techniques, as a substitute of the gold standard RR interval estimation through electrocardiogram. Although the agreement between pulse rate variability (PRV) and HRV has been evaluated in the literature, the reported results are still inconclusive especially when using wearable devices...

Heart transplantation is offered to children with heart failure that is not amenable to medical or surgical therapy. Indications for heart transplant include unrepairable congenital heart disease, failed palliation of congenital heart disease, and cardiomyopathies. There has been tremendous progress in this field since the first heart transplant was performed in 1967. Each year, approximately 500 pediatric heart transplants take place worldwide. Pediatric heart transplant survivors are living longer with their initial transplant...

Beta-adrenoreceptor antagonists (β blockers) reduce systemic O2 delivery and blood pressure (BP) during exercise, but the subsequent effects on O2 extraction within the active limb muscles are unknown. In this study, we examined the effects of the fast-acting, β1 selective blocker esmolol on systemic hemodynamics and leg muscle O2 saturation (near infrared spectroscopy, NIRS) during submaximal leg ergometry. Our main hypothesis was that esmolol would augment exercise-induced reductions in leg muscle O2 saturation...

BACKGROUND: Sodium-glucose linked transporter 2 inhibition recently emerged as a promising therapy for reducing the risk of heart failure (HF) in patients with type 2 diabetes mellitus (T2DM). However, there is a lack of data endorsing its role in symptomatic HF patients. We sought to evaluate the short-term effects of empagliflozin on maximal exercise capacity in these patients. HYPOTHESIS: We postulate tretament with empagliflozin may improve functional capacity in patients with T2DM and established HF...
