Peak oxygen consumption (VO2peak), as measured by cardiopulmonary exercise testing (CPET), is a powerful independent predictor of cardiovascular disease (CVD) and all-cause mortality in a broad range of populations. We assessed the safety and feasibility of CPET in aging long-term HCT survivors, a population at high risk for premature-onset of CVD. Next we examined how organ-specific impairments (e.g. cardiac, pulmonary, hematologic) impact VO2peak after HCT. Twenty consecutive HCT survivors underwent a comprehensive assessment of cardiopulmonary health that included CPET, echocardiography with strain, pulmonary function testing, six-minute walk test, and timed-up and go...

BACKGROUND: Previous studies have demonstrated that global longitudinal strain (GLS) is altered in patients with hypertrophic cardiomyopathy (HCM) in comparison with athletes. Nevertheless, these results rely on studies comparing sedentary patients with HCM with healthy athletes. The aims of this study were to confirm these findings in an appropriate group of athletes with HCM and to study the additive value of novel parameters (i.e., mechanical dispersion and exercise GLS). METHODS: Thirty-six athletes with HCM were prospectively included and were compared with 36 sedentary patients with HCM, 36 healthy athletes, and 36 sedentary control subjects of similar age...

BACKGROUND: -Diagnosis of heart failure (HF) with preserved ejection fraction (HFpEF) is challenging and relies largely on demonstration of elevated cardiac filling pressures (pulmonary capillary wedge pressure, PCWP). Current guidelines recommend use of natriuretic peptides (NT-proBNP) and rest/exercise echocardiography (E/e' ratio) to make this determination. Data to support this practice is conflicting. METHODS: -Simultaneous echocardiographic-catheterization studies were prospectively conducted at rest and during exercise in subjects with invasively-proven HFpEF (n=50) and participants with dyspnea but no identifiable cardiac pathology (n=24)...

BACKGROUNDS: Peak exercise cardiac output (CO) increase is associated with an increase of peak oxygen uptake (VO2), provided that arteriovenous O2 difference [Δ(Ca-Cv)O2] does not decrease. At anaerobic threshold, VO2, is related to CO. We tested the hypothesis that, in heart failure (HF) patients with left ventricular assistance device (LVAD), an acute increase of CO obtained through changes in LVAD pump speed is associated with peak exercise and anaerobic threshold VO2 increase. METHODS: Fifteen of 20 patients bearing LVAD (Jarvik 2000) enrolled in the study successfully performed peak exercise evaluation...

BACKGROUND: We have recently shown that being physically active (PA) counteracts, but not eliminates the increased risk of future cardiovascular disease in over-weight and obese subjects. To investigate this further, we studied the impact of being normal weight, overweight and obese on multiple markers of subclinical cardiovascular disease in relation to physical activity. MATERIALS AND METHODS: At age 70, 1016 subjects were investigated in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study...

INTRODUCTION: The cardiac dysfunction associated with anthracycline-based chemotherapy cancer treatment can exist sub-clinically for decades before overt presentation. Stress echocardiography, the measurement of left ventricular (LV) deformation and arterial haemodynamic evaluation have separately been used to identify sub-clinical cardiovascular (CV) dysfunction in several patient groups including those with hypertension and diabetes. The purpose of the present cross-sectional study was to determine whether the combination of these techniques could be used to improve the characterisation of sub-clinical CV dysfunction in long-term cancer survivors previously treated with anthracyclines...
