Lipid profile, cardiovascular disease and mortality in a Mediterranean high-risk population: The ESCARVAL-RISK study
2017
Introduction The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with allcause mortality and hospitalization due to cardiovascular events in a high-risk population. Methods This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008-2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to corona…
Insulin resistance and acute coronary syndrome
2010
BACKGROUND: Insulin resistance (IR), which can be quantified by HOMA index (fasting glucose X fasting insulin/22.5), is considered the "primum movens" for the development of Metabolic Syndrome. Many authors have suggested that insulin resistance could raise both incidence and mortality of coronary heart disease (CHD). IR is also associated with important predictors of cardiovascular disease, as increased concentration of LDL or triglyceride, decreased concentration of HDL, high systolic blood pressure, visceral obesity. There is accumulating evidence that chronic sub-clinical inflammation, as measured by inflammatory markers as C-reactive protein (CRP) and fibrinogen, is related with insuli…
Carotid artery stiffness as an early marker of vascular lesions in children and adolescents with cardiovascular risk factors.
2010
INTRODUCTION AND OBJECTIVES The availability of a noninvasive marker of vascular lesions that enables their detection in the preclinical phase would be of great benefit for cardiovascular disease prevention. The aim of this study was to investigate the usefulness of a range of indices of arterial wall stiffness in the common carotid artery, as derived using high-resolution Doppler ultrasonography, for identifying vascular damage in children with risk factors. METHODS The study involved 99 children (age, 8-16 years) divided into two groups: 65 had cardiovascular risk factors (45 obesity, 20 dyslipidemia) and 34 were controls. Family histories of cardiovascular risk factors and anthropometric…
Serum vitamin E levels negatively correlate with severity of age-related macular degeneration.
1999
Age-related macular degeneration (AMD) pathogenesis has been related to UV radiation and other factors that may promote increased oxidative damage to the retina. Patients with different AMD grading (n = 25) were compared with an age-matched group of AMD-free subjects (n = 15), both groups older than 60 years. A modification of the AMD grading system is proposed that allows patient grading and not single eye grading. AMD patients showed statistically significant lower serum levels of vitamin E and Zn than AMD-free subjects. Moreover, a negative correlation (Spearman's correlation coefficient r = -0.815, P < 0.001) could be established between AMD grading of both the patients' eyes and serum …
Twenty-four-hour ambulatory heart rate and organ damage in primary hypertension.
2010
The relationship between basal heart rate (HR) and the occurrence of myocardial ischemia, sudden death, cardiovascular mortality have been described. Therefore, further studies are warranted to evaluate the behaviour of heart rate in different scenarios. We sought to determine whether ambulatory heart rate is associated with the presence of target organ damage (TOD) in hypertensive patients.Crossectional study of essential hypertensive patients in whom a twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed. The relationship between TOD and 24 hour ambulatory heart rate (HR) was analyzed.Five hundred and sixty-six patients with arterial hypertension were included (55.8%…
Atherogenic lipoprotein phenotype and LDL size and subclasses in patients with peripheral arterial disease
2006
The type of dyslipidemia in patients with peripheral arterial disease (PAD) is still ill defined. PAD patients often show elevated triglycerides and reduced HDL-cholesterol, two lipid abnormalities usually accompanied by decreased LDL size in the "atherogenic lipoprotein phenotype" (ALP). We investigated (1) whether PAD patients have lower LDL size, (2) altered LDL subclass distribution and (3) the prevalence of ALP. We measured plasma lipids and LDL size and subclasses by gradient gel electrophoresis in 31 adults with intermittent claudication and 31 age-BMI-matched controls. Patients had higher prevalence of hypertension (p = .0132), smoking (p < .0020) and diabetes (p = .0024), with lowe…
Results of the Dyslipidemia International Study (DYSIS)-Middle East: Clinical Perspective on the Prevalence and Characteristics of Lipid Abnormalitie…
2013
BACKGROUND: Therapeutic intervention with low-density lipoprotein cholesterol-lowering agents known as statins has been demonstrated to reduce cardiovascular risk. However, many patients on statin treatment have persistent dyslipidemia and remain at a high risk of cardiovascular disease. Therefore, the objective of this study was to assess the frequency of lipid abnormalities in patients receiving chronic statin treatment. METHODS: As part of an international, cross-sectional, observational study, DYSIS-Middle East enrolled 2,182 patients in the United Arab Emirates (UAE), Saudi Arabia, Lebanon and Jordan. All patients were over 45 years of age and had been on statin treatment for at least …
Difference between Guinea Pig and Rat in the Liver Peroxisomal Response to Equivalent Plasmatic Level of Ciprofibrate
1996
Abstract Guinea pig was previously classified as a species nonresponsive to peroxisome proliferators. However, none of the previous reports was based on pharmacokinetic data. Here, after a comparative pharmacokinetic study between guinea pig and rat, we evaluate the guinea pig liver peroxisomal response to ciprofibrate, a hypolipemic agent and a potent peroxisome proliferator in rat. (1) Pharmacokinetic results show that plasmatic concentrations of ciprofibrate are equivalent in guinea pig and rat when guinea pigs are treated with ciprofibrate at 30 mg/kg twice a day and rats are treated at 3 mg/kg once a day. (2) The treatment of guinea pigs at 30 mg/kg twice a day for 2 weeks leads to a s…
Underlying heart diseases and acute COVID-19 outcomes
2021
Background: The presence of any underlying heart condition could influence outcomes during the coronavirus disease 2019 (COVID-19). Methods: The registry HOPE-COVID-19 (Health Outcome Predictive Evaluation for COVID-19, NCT04334291) is an international ambispective study, enrolling COVID-19 patients discharged from hospital, dead or alive. Results: HOPE enrolled 2798 patients from 35 centers in 7 countries. Median age was 67 years (IQR: 53.0-78.0), and most were male (59.5%). A relevant heart disease was present in 682 (24%) cases. These were older, more frequently male, with higher overall burden of cardiovascular risk factors (hypertension, dyslipidemia, diabetes mellitus, smoking habit, …
Prevalence and Determinants of the Use of Lipid-Lowering Agents in a Population of Older Hospitalized Patients: the Findings from the REPOSI (REgistr…
2017
BACKGROUND: Older patients are prone to multimorbidity and polypharmacy, with an inherent risk of adverse events and drug interactions. To the best of our knowledge, available information on the appropriateness of lipid-lowering treatment is extremely limited. AIM: The aim of the present study was to quantify and characterize lipid-lowering drug use in a population of complex in-hospital older patients. METHODS: We analyzed data from 87 units of internal medicine or geriatric medicine in the REPOSI (Registro Politerapie della Società Italiana di Medicina Interna) study, with reference to the 2010 and 2012 patient cohorts. Lipid-lowering drug use was closely correlated with the clinical prof…
