BACKGROUND: Psoriasis is a chronic inflammatory disease associated with dyslipidemia, cardiovascular events, and mortality. We aimed to assess and compare the effect of treatment of moderate-to-severe psoriasis with adalimumab or phototherapy on vascular inflammation and cardiovascular biomarkers. METHODS AND RESULTS: Randomized, double-blind, trial of adalimumab, phototherapy, and placebo (1:1:1) for 12 weeks, with crossover to adalimumab for 52 weeks total. Outcomes included vascular inflammation by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography and biomarkers of inflammation, insulin resistance, and lipoproteins...

BACKGROUND: Diabetes mellitus and pre-diabetes mellitus are associated with lower body mass indices and increased risk of cardiovascular events (including heart failure) at lower glucose thresholds in Chinese compared with Western cohorts. However, the extent of cardiac remodeling and regulation on cardiac mechanics in lean and nonlean dysglycemic Chinese adults is understudied. METHODS AND RESULTS: We studied 3950 asymptomatic Chinese (aged 49.7±10.7 years; 65% male; body mass index: 24...

BACKGROUND: Heart involvement is the most important prognostic determinant in AL amyloidosis patients. Echocardiography is a cornerstone for the diagnosis and provides important prognostic information. METHODS AND RESULTS: We studied 754 patients with AL amyloidosis who underwent echocardiographic assessment at the Mayo Clinic, including a Doppler-derived measurement of stroke volume (SV) within 30 days of their diagnosis to explore the prognostic role of echocardiographic variables in the context of a well-established soluble cardiac biomarker staging system...

BACKGROUND: The leg-positive pressure maneuver can safely and noninvasively apply preload stress without increase in total body fluid volume. The purpose of this study was to determine whether preload stress could be useful for risk stratification of patients with heart failure with reduced ejection fraction. METHODS AND RESULTS: For this study, 120 consecutive patients with heart failure with reduced ejection fraction were prospectively recruited. The stroke work index was estimated as product of stroke volume index and mean blood pressure, and the E/e' ratio was calculated to estimate ventricular filling pressure...

BACKGROUND: Single photon emission computed tomography (SPECT)/computed tomography (CT) imaging allows for assessment of skeletal muscle microvascular perfusion but has not been quantitatively assessed in angiosomes, or 3-dimensional vascular territories, of the foot. This study assessed and compared resting angiosome foot perfusion between healthy subjects and diabetic patients with critical limb ischemia (CLI). Additionally, the relationship between SPECT/CT imaging and the ankle-brachial index-a standard tool for evaluating peripheral artery disease-was assessed...

BACKGROUND: The main goal of coronary revascularization is to restore myocardial perfusion in case of ischemia, causing coronary artery disease. Yet, little is known on the effect of revascularization on absolute myocardial blood flow (MBF). Therefore, the present prospective study assesses the impact of coronary revascularization on absolute MBF as measured by [15 O]H2 O positron emission tomography and fractional flow reserve (FFR) in patients with stable coronary artery disease. METHODS AND RESULTS: Fifty-three patients (87% men, mean age 58...

BACKGROUND: Current diagnosis of heart failure with preserved ejection fraction (HFpEF) is suboptimal. We tested the hypothesis that comprehensive machine learning (ML) of left ventricular function at rest and exercise objectively captures differences between HFpEF and healthy subjects. METHODS AND RESULTS: One hundred fifty-six subjects aged >60 years (72 HFpEF+33 healthy for the initial analyses; 24 hypertensive+27 breathless for independent evaluation) underwent stress echocardiography, in the MEDIA study (Metabolic Road to Diastolic Heart Failure)...

BACKGROUND: Impaired qualitative and quantitative left ventricular (LV) rotational mechanics predict cardiac remodeling progression and prognosis after myocardial infarction. We investigated whether cardiac rotational mechanics can predict cardiac recovery in chronic advanced cardiomyopathy patients. METHODS AND RESULTS: Sixty-three patients with advanced and chronic dilated cardiomyopathy undergoing implantation of LV assist device (LVAD) were prospectively investigated using speckle tracking echocardiography...

The aorta has 2 main functions, conduit and cushion, and is designed to transmit blood to the periphery and buffer pulsatile stress from ventricular contraction. In the interaction between the structural and functional changes of the aorta, aging and disease processes impact on aortic material properties and hemodynamics. For a comprehensive assessment of changes in aortic structure and function associated with aging and disease, noninvasive cardiovascular imaging techniques, especially magnetic resonance imaging, have recently been developed...

BACKGROUND: In obesity and type 2 diabetes mellitus (T2D), adipose tissue expansion (because of larger adipocytes) results in reduced microvascular density which is thought to lead to adipocyte hypoxia, inflammation, and reduced nutrient delivery to the adipocyte. Adipose tissue microvascular responses in humans with T2D have not been extensively characterized. Furthermore, it has not been determined whether impaired microvascular responses in human adipose tissue are most closely associated with adiposity, inflammation, or altered metabolism...
