Limitation of activity is the most cited symptom described by uncontrolled asthma patients. Assessment of activity limitation can be undertaken through several ways, more or less complex, subjective or objective. Yet little is known about the link between patients sensations and objective measurements. The present review reports the current knowledge regarding activity limitation and symptom perception (i.e., exertional dyspnea) in adult patients with asthma. This work is based on references indexed by PubMed, irrespective of the year of publication...

BACKGROUND: Mortality due to cardiovascular disease is often associated with ventricular arrhythmias. Nowadays, patients with cardiovascular disease are more encouraged to take part in physical training programs. Nevertheless, high-intensity exercise is associated to a higher risk for sudden death, even in apparently healthy people. During an exercise testing (ET), health care professionals provide patients, in a controlled scenario, an intense physiological stimulus that could precipitate cardiac arrhythmia in high risk individuals...

BACKGROUND: The aim of this pilot study was to evaluate if ranolazine (R) could improve insulin resistance (IR) in obese/overweight non-diabetic patients with coronary heart disease (CHD). METHODS: The study enrolled 40 patients with already diagnosed CHD, previous revascularization, residual ischemia at ergometric test and IR. Mean age was 62.4±9years, M/F=31/9. Patients were randomly assigned to one of the two following groups: group 1 (20 patients) started R at dose of 500mg/bid; group 2 (20 patients) increased the dose of beta/blockers or calcium-channel blockers without introducing R...

The ECG signal can be derived from different sources. These include systems for surface ECG, Holter monitoring, ergometric stress tests and systems for telemetry and bedside monitoring of vital parameters, useful to rhythm and ST-segment analysis and ECG screening of cardiac electrical sudden death predictors. A precise ECG diagnosis is based upon a correct recording, elaboration and presentation of the signal. Several sources of artifacts and potential external causes may influence the quality of the original ECG waveforms...

Veteran football players above 40 years have rarely been subject to scientific investigations. This is worrisome because their number is considerable and their cardiovascular risk probably increased. Therefore, a cross-sectional study was conducted in 100 football players between 40 and 63 years of age. This included a medical history and physical examination, venous blood sampling, measurement of resting blood pressure, a resting electrocardiogram (ECG), an exhaustive cycle ergometry and a multistage field test...

BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is an implantable device for antiarrhythmic therapy with no intravascular leads. OBJECTIVE: The purpose of this study was to describe the technical feasibility of combining the S-ICD with other cardiac implantable electronic devices (CIEDs), including pacemakers with transvenous or epicardial electrodes. We also provide the first experience of combining an S-ICD with catheter-based therapies, including cardiac contractility modulation (CCM) and vagus nerve stimulation...

BACKGROUND AND PURPOSE: Low cardiovascular fitness (fitness) in mid- and late life is a risk factor for stroke. However, the respective effects on long-term stroke risk of fitness and muscle strength in early adulthood are unknown. Therefore, we analyzed these in a large cohort of young men. METHOD: We performed a population-based longitudinal cohort study of Swedish male conscripts registered in 1968 to 2005. Data on fitness (by the cycle ergometric test; n=1 166 035) and muscle strength (n=1,563,750) were trichotomized (low, medium, and high)...

OBJECTIVE: To assess physical fitness and physical activity in inflammatory bowel disease (IBD) patients and whether fatigue is associated with impaired physical fitness and impaired physical activity. MATERIALS AND METHODS: Ten patients with quiescent IBD and fatigue (fatigue group [FG]) based on the Checklist Individual Strength-Fatigue score of ≥35 were matched for age (±5 years) and sex with a non-fatigue group (NFG) with IBD. Physical fitness was measured with a cyclo-ergometric-based maximal exercise test, a submaximal 6-min walk test, and a dynamometer test to quantify the isokinetic muscle strength of the knee extensors and flexors...

INTRODUCTION: Dragon Boat training is often suggested to control upper limb edema in breast cancer (BC) survivors, but little information is available regarding the cardiac impact of such activity. The present study evaluates this aspect during a 4-year follow-up of BC survivors. MATERIAL AND METHODS: From 2006 to 2010, 55 women diagnosed with BC in 2005, treated with adjuvant therapy without evidence of metastases, were enrolled for competitive Dragon Boat training...

Vascular endothelial dysfunction is a basic etiologic factor for the development of late clinical complications in patients with diabetes mellitus type 1, such as diabetic retinopathy, diabetic nephropathy (which is characterized at the very beginning by microalbuminuria), and left ventricular cardiac dysfunction. The aims of this study were to determine the prevalence of asymptomatic left ventricular systolic dysfunction in patients with diabetes mellitus type 1 and with or without diabetic retinopathy and microalbuminuria, and to correlate the duration of diabetes with the dynamics of diabetic retinopathy, microalbuminuria and asymptomatic left ventricular dysfunction development in these patients...

Therapy with β-adrenergic blocking agents has been advocated as a potential useful approach in heart failure. Recent studies suggest that histologic parameters may be helpful in assessing the effectiveness of β-blocker treatment in dilated cardiomyopathy (DCM). In order to predict the response to β-blockers in DCM, fibrous tissue was evaluated at endomyocardial biopsy (EMB) in 45 patients (pts) with a mean left ventricular ejection fraction of 0.28 ± 0.07, who were successively long-term treated with metoprolol (M) (mean dosage 138 ±26 mg/die)...

BACKGROUND: Patients with a small aortic annulus, that is ≤ 23 mm, constitute a challenge for the surgeon, because they are at high risk of patient-prosthesis mismatch. Stentless valves provide better hemodynamic performance at rest and during exercise than stented valves, and are advocated in this group of patients. A new-generation stented valve, the Trifecta (St. Jude), has recently become available with improved hemodynamics. The aim of this study was to compare the hemodynamic performance of Freestyle (Medtronic) and Trifecta at rest and during exercise in patients with a small aortic annulus...

33 untrained test subjects (16 males and 17 females aged 18) have been studied for one year for their blood fibrinolysis reaction to a one-time 20-minute bicycle-ergometric large-capacity load (N male = 2.66 watt/kg, N female = 2.3 watt/kg). It is known that at rest the blood fibrinolytic activity (FA) has its seasonal characteristics: it is relatively high in the autumn and spring and low in the winter and summer. On the average, in the winter and in the summer physical activity stimulates the blood clot lysis whereas in the autumn and in the spring it does not...

BACKGROUND: Aerobic exercise capacity is considered as an independent prognostic factor for cardiovascular disease and mortality. It is usually expressed in maximal oxygen consumption (VO2(max)) or metabolic equivalent (MET) and is measured by spiroergometry or calculated by a regression formula based on maximal performance achieved. Obesity is associated with reduced physical performance and increased cardiovascular mortality. The aim of our study was to describe the ergometric and cardiovascular profile of patients of an obesity clinic, and to compare a direct measure of VO2(max) with an indirect by a regression formula and to...

OBJECTIVES: To evaluate if the estimation of the maximal oxygen consumption (MO2C) in METs (metabolic equivalents) by means of the table proposed in the guidelines of the Spanish Society of Cardiology is a sufficiently reliable method when applied to the bicycle exercise test. MATERIAL AND METHODS: The MO2C in METs was obtained by gas-exchange analysis on bicycle ergometer tests in 97 healthy subjects (group i). It was compared with the estimate of METs using the table in which only watts and patient's weight were included...

PURPOSE: Physical exercise, especially intense physical exercise, causes a number of unfavorable changes, including an increase in the level of pro-inflammatory cytokines with the resultant sequestration of iron in macrophages and decreased iron absorption. This can lead to a reduced supply of iron for erythroid progenitor cells and promote the development of anemia. METHOD: This study included a group of 20 rowing athletes, members of the National Polish Rowing Team...

Standard exercise testing (ET) comprises progressive exercise provocation with cardiovascular monitoring. Exercise tolerance is estimated by workload. Cardiopulmonary exercise testing (CPX) is a non-invasive measurement of ventilatory gas exchange which provides more accurate quantifications of cardiorespiratory fitness (CRF). Workload is usually increased stepwise in ET and continuously (ramp) in CPX. Our aim was to examine the comparability of the results. Thirty two healthy volunteers (17 females/15 males, age 26...
