BACKGROUND: Cardiovascular disease is the principle cause of death in patients with elevated liver fat unrelated to alcohol consumption, more so than liver related morbidity and mortality. OBJECTIVES: The aim of this study was to evaluate the relationship between liver fat and cardiac and autonomic function. Secondly, how impairment in cardiac and autonomic function is influenced by metabolic risk factors. METHODS: Cardiovascular and autonomic function were assessed in 96 sedentary individuals: 1) NAFLD (n = 46, hepatic steatosis >5% by magnetic resonance spectroscopy), 2) Hepatic steatosis and alcohol (DAFLD) (n = 16, >5%, consuming >20g/day of alcohol) and 3) CONTROLS (n = 34, no cardiac, liver or metabolic disorders, <20g/day of alcohol)...

With five-year survival of children with cancer exceeding 80% in developed countries, premature cardiovascular disease is now a major cause of early morbidity and mortality. In addition to the acute and chronic cardiotoxic effects of anthracyclines, related chemotherapeutics, and radiation, a growing number of new molecular targeted agents may also have detrimental effects on the cardiovascular system. Survivors of childhood cancer also may have earlier development of conventional cardiovascular risk factors such as hypertension, dyslipidemia, and diabetes, which further increase their risk of serious cardiovascular disease...

MOTIVATION: Left heart failure (LHF) is the most common cause of pulmonary hypertension, which confers an increase in morbidity and mortality in this context. Pulmonary vascular resistance has prognostic value in LHF but otherwise the mechanical consequences of LHF for the pulmonary vasculature and right ventricle remain unknown. We sought to investigate mechanical mechanisms of pulmonary vascular and right ventricular dysfunction in a rodent model of LHF to address the knowledge gaps in understanding disease pathophysiology...

BACKGROUND: Cardiac involvement in myotonic dystrophy type 1 (MD1) includes conduction disease, arrhythmias, and left-ventricular (LV) systolic dysfunction leading to an increased sudden cardiac death risk. An understanding of the interplay between electrical and structural myocardial changes could improve the prediction of adverse cardiac events. We aimed to explore the relationship between signs of cardiomyopathy by conventional and advanced cardiovascular magnetic resonance (CMR), and electrical abnormalities in MD1...

(1) Background: Myocardial dysfunction in patients with sepsis is not an uncommon phenomenon, yet reported results are conflicting and there is no objective definition. Measurement of troponin may reflect the state of the heart and may correlate with echocardiographically derived data. This study aimed to evaluate the role of admission and peak troponin-I testing for the identification of sepsis-induced myocardial dysfunction (SIMD) by transthoracic echocardiography (TTE). (2) Methods: This was a retrospective cohort study using a prospective registry of septic shock at an Emergency Department from January 2011 and April 2017...

The prevalence of type 2 diabetes mellitus (T2DM) in the elderly grew sharply over the last decade. Reduced insulin sensitivity and secretory capacity, weight gain, sarcopenia, and elevated adiposity are all common metabolic and body changes in the aging population that favor an increased risk of hypoglycemia, frailty syndrome, falls, and cognitive dysfunction. First line antidiabetic therapy is frequently not safe in older individuals because of its high risk of hypoglycemia and prevalent co-morbid diseases, such as chronic kidney disease, osteoporosis, cardiovascular disease, and obesity...

Objective: The attenuation of physiological nocturnal decline of blood pressure (BP) - called nondipper pattern - has previously been reported to be associated with target organ damage in hypertensive subjects. However, this association remains debated and poorly studied in normotensive patients. The present study aimed to investigate the association between nondipper pattern and subclinical cardiovascular and renal damage in an initially healthy population-based cohort study. Methods: The STANISLAS Cohort is a single-center, familial longitudinal cohort comprised of 1006 families (4295 subjects) recruited in 1993-1995 for a 5-year periodic health examination...

BACKGROUND: Activation of the NLRP3 inflammasome is a primary driver of sterile inflammation in response to myocardial ischemia reperfusion. Pharmacologic inhibitors of the NLRP3 inflammasome are being developed. We proposed that OLT1177 (dapansutrile), a novel NLRP3 inflammasome inhibitor, could preserve myocardial function after ischemia reperfusion injury in the mouse. METHODS: We used an experimental murine model of myocardial ischemia reperfusion injury through transient ligation of the left coronary artery, and measured the effects of OLT1177 (6, 60 or 600 mg/kg intraperitoneal dose) on infarct size at pathology and on systolic cardiac function at echocardiography...

Ischemic mitral regurgitation (IMR) is a frequent complication after acute myocardial infarction (AMI) associated with a worse prognosis. The pathophysiological mechanisms of IMR are not fully understood, but it is known to be a complex process in which ventricular remodelling is the main causal factor. The various imaging techniques in cardiology and echocardiography fundamentally have contributed significantly to clarify the mechanisms that cause and progressively aggravate IMR. At present, different therapeutic options, the most important of which are cardio-surgical, address this problem...

A 28-year-old female presented with fulminant lymphocytic myocarditis. She developed cardiogenic shock, frequent sustained ventricular tachycardia, and fibrillation (VT and VF). The left ventricular ejection fraction improved from 5% to 40% after medical therapy, but the right ventricular systolic dysfunction and enlargement persisted. In addition, sustained VTs, requiring direct current cardioversion, occurred during oral administration of amiodarone following intravenous amiodarone, even after percutaneous stellate ganglion block...
