The relationships between lipid ratios and arterial stiffness

2017

Although dyslipidemia is associated with cardiovascular disease, there are conflicting data about the role of serum lipids and their ratios in promoting arterial stiffness. The authors aimed to compare serum lipid profiles to predict arterial stiffness, which was assessed by brachial‐ankle pulse wave velocity in young Chinese men. A total of 1015 participants aged 18 to 44 years without serious comorbidities were recruited for conventional detection. Anthropometrics, brachial‐ankle pulse wave velocity, serum lipids, and other laboratory data were measured. Univariate analysis and multivariate logistic regression were performed to examine the relationship between serum lipid profiles and bra…

Inappropriately high left ventricular mass: Marker of very high cardiovascular risk in patients with chronic kidney disease

2012

There is increasing knowledge of the burden of cardiovascular (CV) diseases affecting patients with chronic kidney disease (CKD). CV diseases are the main cause of death in the CKD population, and the majority of patients with CKD die before ever reaching the end-stage renal disease; in fact, for patients with CKD, the risk of a fatal CV event is much higher than the risk to develop end-stage renal disease. Although patients with CKD manifest a high prevalence of traditional CV risk factors, this does not fully account for the burden of CV diseases in CKD.

Human Hypertension Is Characterized by a Lack of Activation of the Antihypertensive Cardiac Hormones ANP and BNP

2012

ObjectivesThis study sought to investigate plasma levels of circulating cardiac natriuretic peptides, atrial natriuretic peptide (ANP) and B-type or brain natriuretic peptide (BNP), in the general community, focusing on their relative differences in worsening human hypertension.BackgroundAlthough ANP and BNP are well-characterized regulators of blood pressure in humans, little is known at the population level about their relationship with hypertension. The authors hypothesized that hypertension is associated with a lack of activation of these hormones or their molecular precursors.MethodsThe study cohort (N = 2,082, age >45 years) was derived from a random sample from Rochester, Minnesota, …

Cardiac involvement in rheumatoid arthritis: Evidence of silent heart disease

1995

Background : Rlieumatoid arthritis (RA) is a systemic disease involving many organ systems and is frequently accompanied by cardiac alterations. However, there is considerable disagreement concerning the cardiac abnormalities found in patients with RA. The purpose of our investigation was to determine, by a non-invasive method such as echocardiography, the nature and extent of cardiac involvement in RA patients with no symptoms of cardiac disease, in comparison with a control sample. Methods : We selected 35 patients affected by rheumatoid arthritis (five men, 30 women), aged 51 ± 11 years. No patient had either symptoms of cardiac disease or extra cardiac complaint. As a control group we s…

Detection of Left Ventricular Systolic Dysfunction in Cardiac Amyloidosis with Strain Rate Echocardiography .

2006

Background We examined the potential role of Doppler myocardial imaging including tissue velocity imaging, strain imaging, and strain rate imaging for detection of left ventricular systolic dysfunction in cardiac amyloidosis (CA) and determined the minimum dataset required to make the diagnosis. Methods and Results Doppler myocardial imaging was performed in 103 patients with amyloidosis (AL). Peak longitudinal systolic tissue velocity, systolic strain rate (sSR), and systolic strain (sS) were determined for 16 left ventricular segments. Radial and circumferential sSR and sS were also measured. Patients with increased left ventricular wall thickness were classified with advanced-CA, and the…

Clinical findings of Takotsubo cardiomyopathy: results from a multicenter international study

2008

BACKGROUND: Takotsubo cardiomyopathy consists of reversible systolic left ventricular apical ballooning associated with chest pain. Electrocardiographic abnormalities and the minimal rise of serum cardiac markers are similar to those in acute myocardial infarction, but without evidence of myocardial ischemia or injury. To date, many reports concerning this kind of acute reversible heart failure have been published, but the information available about the management of affected patients is scarce and the clinical data are incomplete. AIMS: In the present study, we report a collection of 40 patients who were affected by Takotsubo cardiomyopathy obtained in a multicentric international study, …

Studies on vinblastine-induced autophagocytosis in mouse liver. III. A quantitative study.

1982

The microtubule inhibitor vinblastine (25 mg/kg, i.p.) induces autophagocytosis in mouse hepatocytes. The formation of autophagic vacuoles, their contents, and other cellular changes after vinblastine injection in hepatocytes, were studied by light and electron microscopic morphometric analysis. The volume density of autophagic vacuoles increased significantly during the experimental period (24 h). This increase was due to the significant increase in their number, which was approximately 5-fold 4 h, 12 h and 24 h after vinblastine injection. The mean volume of the autophagic vacuoles increased significantly 1 h after vinblastine injection, at which time the formation of new autophagic vacuo…

Second asymptomatic carotid surgery trial (ACST-2): a randomised comparison of carotid artery stenting versus carotid endarterectomy.

2021

Summary Background Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence. Methods ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligib…

Pioglitazone Reduces Secondary Brain Damage after Experimental Brain Trauma by PPAR-γ-Independent Mechanisms

2011

Inflammatory and ischemic processes contribute to the development of secondary brain damage after mechanical brain injury. Recent data suggest that thiazolidinediones (TZDs), a class of drugs approved for the treatment of non-insulin-dependent diabetes mellitus, effectively reduces inflammation and brain lesion by stimulation of the peroxisome proliferator-activated receptor-γ (PPAR-γ). The present study investigates the influence of the TZD pioglitazone and rosiglitazone on inflammation and secondary brain damage after experimental traumatic brain injury (TBI). A controlled cortical impact (CCI) injury was induced in male C57BL/6 mice to investigate following endpoints: (1) mRNA expression…
