Introduction: Chronic renal disease is associated with increased cardiovascular (CV) mortality. Cardiac autonomic neuropathy (CAN) is predictive of mortality for diseases that affect the autonomic nervous system. We prospectively evaluated the prognostic value of indexes of left ventricular (LV) function and CAN in all-cause and CV mortality of patients with end-stage renal failure (ESRF). Methods: A total of 133 patients with ESRF were recruited. LV function was evaluated by echocardiography, whereas cardiac autonomic function was assessed using the battery of the 4 standardized tests proposed by Ewing...

Background: The coronary slow flow phenomenon (CSFP) is the slow passage of the angiographic contrast agent to the distal portion of the coronary artery in the absence of significant stenosis. We evaluated the left atrial (LA) function in patients with the CSFP using two-dimensional speckle-tracking echocardiography (2DSTE). Methods: The LA function was compared through 2DSTE between 36 patients with the CSFP and 36 participants with a normal coronary flow. The two groups were matched for age, sex, hypertension, diabetes mellitus, and the left ventricular function...

Leisure-time physical activity (LTPA) is associated with longevity in patients with coronary artery disease (CAD). However, less is known about prognostic significance of longitudinally assessed LTPA in patients with stable CAD. The present study assessed the relationship between changes in LTPA and cardiac mortality in patients with CAD. Patients with angiographically documented CAD (n = 1,746) underwent clinical examination and echocardiography at the baseline. Lifestyle factors, including LTPA (inactive, irregularly active, active, highly active), were surveyed at baseline and after 2 years' follow-up...

BACKGROUND: Diabetes mellitus is a risk factor for coronary artery disease and diabetic cardiomyopathy, and adversely impacts outcomes following coronary artery bypass grafting. Current treatments focus on macro-revascularization and neglect the microvascular disease typical of diabetes mellitus-induced cardiomyopathy (DMCM). We hypothesized that engineered smooth muscle cell (SMC)-endothelial progenitor cell (EPC) bi-level cell sheets could improve ventricular dysfunction in DMCM. METHODS: Primary mesenchymal stem cells (MSCs) and EPCs were isolated from the bone marrow of Wistar rats, and MSCs were differentiated into SMCs by culturing on a fibronectin-coated dish...

Advanced glycation end-products (AGEs) play a role in the pathophysiology of diabetes mellitus (DM) and possibly hypertension (HTN). In experimental DM, AGEs accumulate in myocardium. Little is known about AGEs in human myocardium. We quantified abundance, localization, and functional correlates of the AGE carboxymethyl lysine (CML) in left ventricular (LV) myocardium from patients undergoing coronary bypass grafting (CBG). Immunoelectron microscopy was used to quantify CML in epicardial biopsies from 98 patients (71 M, 27 F) with HTN, HTN + DM or neither (controls), all with normal LV ejection fraction...

BACKGROUND AND AIMS: Pulmonary hypertension is common in patients with end-stage renal disease, and portends a poor prognosis. There are little data in this population, and previous studies have not evaluated quantitative changes in hemodynamics over time while on maintenance dialysis. This study sought to estimate changes in pulmonary artery systolic pressure (PASP) and right ventricular function over time, and to predict PASP change using clinical variables routinely available at time of initial measurement, in patients on maintenance dialysis...

INTRODUCTION: Coronary microvascular dysfunction (MVD) may contribute to the pathogenesis of heart failure with preserved ejection fraction (HFpEF). Speckle-tracking echocardiography is a feasible and reproducible method for identifying abnormalities in left ventricular (LV) and left atrial (LA) function among HFpEF patients. By assessing myocardial flow reserve (MFR), positron emission tomography (PET) imaging enables quantitative assessment of coronary MVD. We hypothesized that, in patients with risk factors for HFpEF and normal epicardial perfusion on cardiac PET, abnormal MFR is associated with LV diastolic dysfunction (DD) and reduced LV and LA strain...

Diabetes mellitus has been associated with changes in the structure and function of the myocardium manifesting in the early stages of the disease as subtle systolic and diastolic dysfunction; myocardial strain imaging has recently been favored over dobutamine stress echocardiography for early detection of diabetic cardiomyopathy. We report a case of an elderly diabetic patient presenting with pulmonary edema in whom at rest echocardiographic parameters including strain rate were all within normal range, while dobutamine stress echocardiography induced a deep systolic deterioration unmasking an early-stage diabetic cardiomyopathy...

AIMS: Diabetes is associated with higher arterial stiffness-an early marker of cardiovascular disease. The coupling between arterial stiffness and myocardial function is still unresolved. We investigate associations between arterial stiffness and early myocardial impairment assessed with advanced echocardiography. METHODS: In 305 type 1 diabetes (T1D) patients without known heart disease and with normal left ventricular ejection fraction (LVEF) (biplane LVEF > 45%), we measured arterial stiffness as pulse wave velocity (PWV) and performed conventional and speckle-tracking echocardiography assessing global longitudinal strain (GLS) as a measure of systolic myocardial function...

BACKGROUND: It is unknown whether canagliflozin, a selective sodium glucose co-transporter 2 inhibitor, reduces epicardial adipose tissue (EAT) thickness, which is associated with insulin resistance and is a risk factor for coronary artery disease. METHODS AND RESULTS: We administered 100 mg of canagliflozin for 6 months to 13 patients with type 2 diabetes mellitus. We evaluated glycemic control, visceral adipose tissue (VAT) area and subcutaneous adipose tissue (SAT) area, and skeletal muscle mass by using impedance methods, and EAT thickness by using echocardiography...

BACKGROUND: Asymptomatic left ventricular (LV) dysfunction is highly prevalent in type 2 diabetes patients. Unlike the other hypoglycemic drugs, SGLT2 inhibitors have shown potential benefits for reducing cardiovascular death and risk factors, aside from lowering plasma glucose levels. With this study we aim at determining whether the treatment with empagliflozin is associated with an improvement in LV functions in diabetic patients with asymptomatic LV dysfunction against Sitagliptin, which is presumably neutral on myocardial function...
