There are so far only a few reported cases of acute fulminant hepatic failure resulting from acute cardiomyopathy. This is a rare occurrence, especially in patients that do not exhibit any signs and symptoms of acute cardiac decompensation. We report a case of fulminant liver failure with nondiagnostic work up for the common causes of liver failure. This patient had concurrent history of congestive heart failure, but did not have acute decompensation. Right upper quadrant sonogram revealed hepatomegaly of 15 cm, trace amount of perihepatic ascites, pericholecystic fluid, and also thickened edematous gallbladder wall with no stones, no common bile duct stones, and no portal vein thrombosis...

BACKGROUND: Hypertension is an important risk factor for adverse cardiovascular events including stroke, myocardial infarction, heart failure and renal failure. The main goal of treatment is to reduce these events. Systematic reviews have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older. We wanted to know what the effects of therapy are in people 18 to 59 years of age...

Intraventricular pressure differences (IVPDs) govern left ventricular (LV) efficient filling and are a significant determinant of LV diastolic function. Our primary aim is to assess the performance of available methods (color M-mode (CMM) and 1D/2D MRI-based methods) to determine IVPDs from intracardiac flow measurements. Performance of three methods to calculate IVPDs was first investigated via an LV computational fluid dynamics (CFD) model. CFD velocity data were derived along a modifiable scan line, mimicking ultrasound/MRI acquisition of 1D (IVPDCMM/IVPD1D MRI) and 2D (IVPD2D MRI) velocity-based IVPD information...

BACKGROUND: Tolvaptan slows progression of autosomal dominant polycystic kidney disease (ADPKD) by antagonizing the vasopressin-cAMP axis. Nitric oxide (NO) stimulates natriuresis and diuresis, but its role is unknown during tolvaptan treatment in ADPKD. METHODS: Eighteen patients with ADPKD received tolvaptan 60 mg or placebo in a randomized, placebo-controlled, double blind, crossover study. L-NMMA (L-NG-monomethyl-arginine) was given as a bolus followed by continuous infusion during 60 min...

Background: Renal denervation reduces blood pressure (BP) and sympathetic drive in experimental animal models, but the effect of this intervention on sympathetic activity in patients with treatment-resistant hypertension is still unclear. Methods: In an incident series of 29 patients with treatment-resistant hypertension, we performed serial measurements (n = 123) of muscle sympathetic nerve activity (MSNA, microneurography) and standardized BP measurements. Data were analysed by mixed linear modelling (MLM) and by regression analysis of time-integrated changes of both MSNA and synchronous, standardized (in-lab) BP measurements...

BACKGROUND: Diabetes mellitus induces structural and functional cardiac alterations that can result in heart failure. Left ventricular (LV) shape is a dynamic component of cardiac geometry influencing its contractile function. However, few data are available comparing LV shape index in diabetic and nondiabetic patients without overt coronary artery disease after balancing for coronary risk factors. METHODS: We studied 1168 patients with normal myocardial perfusion and normal LV ejection fraction on stress gated single-photon emission computed tomography (SPECT) imaging...

BACKGROUND: Although a recent randomized trial found no difference between intensive and standard blood pressure (BP) control in patients with diabetes mellitus (DM), the debate over the optimal BP target continues. Thus, the present study investigated the effect of BP on the subclinical left ventricular (LV) function and structural changes in diabetic patients. METHOD: A total of 2649 patients with DM who received echocardiography were enrolled in this study. Study population was stratified by three groups according to BP and presence of hypertension (normal, <130/80mmHg; prehypertension, ≥130/80mmHg without hypertension; hypertension, ≥140/90mmHg or history of hypertension)...

The maintenance of blood pressure upon the assumption of upright posture depends on rapid cardiovascular adaptations driven primarily by the autonomic nervous system. Failure of these compensatory mechanisms can result in orthostatic hypotension (OH), defined as sustained reduction in systolic blood pressure > 20 mm Hg or diastolic blood pressure > 10 mm Hg within 3 minutes of standing or > 60° head-up tilt. OH is a common finding, particularly in elderly populations, associated with cardiovascular and cerebrovascular morbidity and mortality...

The benefits of controlling blood pressure to levels < 140/90 mm Hg are well established, but the risks and benefits of further reductions in blood pressure are less clear. A recent observational study using pooled data from 2 large randomized trials of renin-angiotensin system blockers suggested no added benefit and some increased risk of cardiovascular events with achieved blood pressures < 120 mm Hg systolic or 70 mm Hg diastolic. Caveats of observational studies notwithstanding, these results add to the ongoing controversy over the optimal blood pressure target for high-risk individuals...

C1q/tumor necrosis factor-related protein-3 (CTRP3) is an adipokine that protects against myocardial infarction-induced cardiac dysfunction through its pro-angiogenic, anti-apoptotic, and anti-fibrotic effects. However, whether CTRP3 can directly affect the systolic and diastolic function of cardiomyocytes remains unknown. Adult rat cardiomyocytes were isolated and loaded with Fura-2AM. The contraction and Ca(2+) transient data was collected and analyzed by IonOptix system. 1 and 2μg/ml CTRP3 significantly increased the contraction of cardiomyocytes...

AIM: Critical care ultrasound (CCUS) has been used by many Intensive Care Units(ICUs) worldwide, so as to guiding the diagnosis and the treatment. However, none of the publications currently systematically describe the utilization of CCUS to analyze the characteristics of hemodynamics and lung pathology upon the new admission to ICU and its potential role in patients' prognosis prediction. In this retrospective clinical study, we have demonstrated and analyzed the characteristics of hemodynamics and lung pathology assessed by CCUS and investigated its potential to predict patient outcome...
