Current guidelines for exercise training in coronary patients state that in the presence of exercise-induced ischemia, the heart rate during exercise should be at least 10 beats/min below the heart rate associated with an ST segment depression of 1 mm or greater. For patients with a relatively low ischemic threshold, ...

PURPOSE: This study determined the effect of a structured isotonic strength training (ST) program on left ventricular (LV) function (ejection fraction, stroke volume, and end-diastolic and end-systolic volumes) and physical fitness (6-minute walk test, upper body strength, lower body strength, and body composition) in patients with New York Heart Association ...

Exercise-induced ST-segment elevation in patients without previous myocardial infarction is a relatively uncommon finding. When it does occur, it may be associated with significant coronary artery disease or coronary vasospasm. Here we describe a case of exercise-induced ST-segment elevation in both anterior and inferior leads in a patient with a ...

Hepatocyte growth-promoting factor (pHGF) has the greatest potential as a therapeutic agent for vascular growth factor. The aim of this study was to investigate the effect of pHGF on myocardial ischemia and exercise capacity in patients with severe coronary artery disease (CAD). Forty-nine patients were enrolled for a two week ...

BACKGROUND: The appearance of a discrete upward deflection of the ST segment termed "the ST hump sign" (STHS) during exercise testing has been associated with resting hypertension and exaggerated blood pressure response to exercise. OBJECTIVE: We investigated the prevalence and clinical significance of this sign in a population of patients ...

The paraventricular nucleus (PVN) of the hypothalamus is an important site for autonomic regulation, where gamma-aminobutyric acid (GABA) system plays an important role. The central mechanisms underlying modulatory effects of exercise training have yet to be characterized. Our objective was to analyze the effects on the autonomic modulation and hemodynamic ...

PURPOSE: It is well known that patients with arterial hypertension frequently present with ischemic electrocardiographic changes during exercise testing without actually having coronary artery disease (CAD). The purpose of this study was to establish additional electrocardiographic criteria during exercise testing for detecting CAD in hypertensive patients with ischemic ST-segment response. ...

The exercise electrocardiogram is a commonly used non-invasive and inexpensive method for detection of electrocardiogram (ECG) changes secondary to myocardial ischemia. Reversible ST-segment depression is the characteristic finding associated with exercise-induced, demand-driven ischemia in patients with significant coronary obstruction but no flow limitation at rest. The exercise-induced ST-segment depression in ...

Silent electrocardiographic ST change predicts future coronary events in patients with coronary heart disease (CHD), but the prognostic significance of asymptomatic ST-segment depression with respect to sudden cardiac death in subjects without apparent CHD is not well known. We investigated the association between silent ST-segment depression during and after maximal ...

The exercise electrocardiogram is a commonly used non-invasive and inexpensive method for detection of electrocardiogram (ECG) changes secondary to myocardial ischemia. It has been reported that in patients with a first myocardial infarction and without residual ischemia, exercise-induced ST-segment elevation in Q leads is related to a more damaged coronary ...

We investigated the response of insulin-like growth factor (IGF- I), insulin-like growth factor binding protein-3 (IGFBP-3) and some hormones, i.e., testosterone (T), growth hormone (GH), cortisol (C), and insulin (I), to maximal exercise in road cyclists with and without diagnosed left ventricular hypertrophy. M-mode and two-dimensional Doppler echocardiography was performed ...

In symptom-free subjects, exercise tolerance testing (ETT) has a doubtful utility for detecting latent coronary heart disease (CHD) because of frequent false positives, but it may be valuable for predicting future CHD. To clarify the latter question, we calculated CHD incidence associated with presence or absence of ETT-induced abnormalities of ...

CONTEXT: In the population at large, regular exercise is associated with reduced anxious and depressive symptoms. Results of experimental studies in clinical populations suggest a causal effect of exercise on anxiety and depression, but it is unclear whether such a causal effect also drives the population association. We cannot exclude ...

Hypericins are biologically active constituents of Hypericum perforatum (St John's wort). It is likely that emodin anthrone, an anthraquinone precursor of hypericins, is biosynthesized via the polyketide pathway by type III polyketide synthase (PKS). A PKS from H. perforatum, HpPKS2, was investigated for its possible involvement in the biosynthesis of ...

Exercise treadmill testing (ETT) is a well-accepted examination for patients with suspected coronary artery disease (CAD), and exercise induced ST-segment deviation is commonly used for CAD detection. However, recent evidence shows that systolic blood pressure (SBP) changes during and after exercise were associated with CAD severity, risk of acute myocardial ...

BACKGROUND: EMR traditionally performed by using normal saline solution (NS) plus epinephrine (E) as a submucosal fluid cushion does not maintain the submucosal elevation for a prolonged time. It was hypothesized that 50% dextrose (D(50)) plus E as a hypertonic, inexpensive, and easily available solution might be an ideal alternative ...

Subdivision of the human liver into eight portal venous segments (according to Couinaud) is largely established in the anatomical and clinical community. However, this concept is challenged by an increasing number of surgical and radiological reports. We reexamined the intrahepatic portal venous architecture to understand the inconsistencies published. For this ...

Experimental studies suggest that alcohol may have protective effects similar to that of ischemic preconditioning (IPC). The acute effects of alcohol on IPC in humans, however, are poorly known. In this study, we assessed the effect of alcohol administration on the warm-up phenomenon, as an expression of IPC, in patients ...

Two experiments studied how listeners weight the level information from different portions of a noise consisting of ten temporal segments, the levels of which were sampled independently from a normal distribution. If a gradual increase in level ("fade-in") is imposed on the first few segments in such a sound, temporal ...

Apnea, depression, and metabolic abnormalities are independent predictors of excessive daytime sleepiness (EDS) in patients with sleep apnea. Exercise is beneficial for apnea, depression, and metabolic abnormalities; however, its association with EDS is not known. To evaluate the contribution of lack of regular exercise, depression, and apnea severity on daytime ...

Compared with standard test criteria, simple heart rate (HR) adjustment of ST depression during exercise electrocardiography can improve the identification and assessment of underlying coronary artery disease. Since heart rate during exercise drives progressive ST segment depression in the presence of coronary obstruction that limits flow reserve, the ST/HR index ...

The main problem during pulse check in out-of-hospital cardiac arrest is the discrimination between normal pulse-generating rhythm (PR) and pulseless electrical activity (PEA). It has been suggested that circulatory information can be acquired by measuring the thoracic impedance via the defibrillator pads. To investigate this, we performed an experimental study ...

BACKGROUND: An ambulatory 24-hour BP-monitoring (ABPM) is of paramount importance, while patients are engaged in their usual activities, for a better representation of blood pressure (BP). ABPM provides not only automated measurements of brachial-artery pressure over a 24-hour period but also a highly reproducible circadian profile. The purpose of this ...

During combing of hair, longer fiber breaks (>2.5 cm) occur principally by impact loading of looped crossover hairs, while short segment breaks (<2.5 cm) occur primarily by end wrapping. Brushing provides breakage similarly but with a higher ratio of long-to-short segment breaks, and the ratio of long-to-short segment breaks (L/S) ...
