Global, regional, and country-specific lifetime risks of stroke, 1990 and 2016
2018
Background: The lifetime risk of stroke has been calculated in a limited number of selected populations. We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases.Methods: We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older. Estimates of the lifetime risks in the years 1990 and 2016 were compared. Countries were categorized into quintiles of the sociode…
Noradrenaline depleting and blood pressure lowering activity of threo-corbadrine
1968
Abstract Threo-corbadrine caused a long-lasting depletion of noradrenaline in the heart and in mesenteric vessels and lowered the blood pressure of normal and renal hypertensive rats. It is suggested that threo-cobadrine decreases vascular tone by acting peripherally as a substitute adrenergic transmitter.
Adverse metabolic response to regular exercise: Is it a rare or common occurrence?
2012
Background. Individuals differ in the response to regular exercise. Whether there are people who experience adverse changes in cardiovascular and diabetes risk factors has never been addressed. Methodology/Principal Findings. An adverse response is defined as an exercise-induced change that worsens a risk factor beyond measurement error and expected day-to-day variation. Sixty subjects were measured three times over a period of three weeks, and variation in resting systolic blood pressure (SBP) and in fasting plasma HDL-cholesterol (HDL-C), triglycerides (TG), and insulin (FI) was quantified. The technical error (TE) defined as the within-subject standard deviation derived from these measur…
Non-alcoholic fatty liver disease and the development of nephrolithiasis: A cohort study.
2017
Background Non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation or precursor of metabolic syndrome, may increase nephrolithiasis, a renal manifestation of insulin resistance, but the prospective association between NAFLD and incident nephrolithiasis has not been evaluated. We examined the association of NAFLD with the development of nephrolithiasis in a large cohort of Korean men and women. Methods We performed a cohort study of 208,578 Korean adults who underwent a health checkup examination between January 2002 and December 2014 and were followed-up annually or biennially through December 2014. NAFLD was defined as the presence of fatty liver in the absence of excessive alco…
Lactoferricin B-derived peptides with inhibitory effects on ECE-dependent vasoconstriction
2010
Endothelin-converting enzyme (ECE), a key peptidase in the endothelin (ET) system, cleaves inactive big ET-1 to produce active ET-1, which binds to ET(A) receptors to exert its vasoconstrictor and pressor effects. ECE inhibition could be beneficial in the treatment of hypertension. In this study, a set of eight lactoferricin B (LfcinB)-derived peptides, previously characterized in our laboratory as angiotensin-converting enzyme (ACE) inhibitory peptides, was examined for their inhibitory effects on ECE. In vitro inhibitory effects on ECE activity were assessed using both the synthetic fluorogenic peptide substrate V (FPS V) and the natural substrate big ET-1. To study vasoactive effects, an…
Role of HDL function and LDL atherogenicity on cardiovascular risk: a comprehensive examination
2019
[Background] High-density lipoprotein (HDL) functionality and low-density lipoprotein (LDL) atherogenic traits can describe the role of both particles on cardiovascular diseases more accurately than HDL- or LDL-cholesterol levels. However, it is unclear how these lipoprotein properties are particularly affected by different cardiovascular risk factors.
Association of central and peripheral pulse pressure with intermediate cardiovascular phenoytpes
2012
Objective: We assessed the relationship between pulse pressure and intermediate cardiovascular phenotypes in a middle-aged cohort with high prevalence of hypertension. Background: It has been suggested that central pulse pressure (cPP) is a better predictor of cardiovascular outcome than peripheral pulse pressure (pPP), particularly in the elderly. Yet, it is unclear if cPP provides additional prognostic information to pPP in younger individuals. Methods: In 535 individuals we assessed cPP and pPP as well as the intermediate cardiovascular phenotypes pulse wave velocity (PWV; SphygmoCor, Complior, PulsePen), carotid intima-media thickness (C-IMT; carotid ultrasound), left-ventricular mass i…
High blood pressure responders show largest increase in heartbeat perception accuracy after post-learning stress following a cardiac interoceptive le…
2020
Mental disorders with physical symptoms, e.g. somatic symptom disorder, are characterized by altered interoceptive accuracy (IAc), which can be explained by individual differences in interoceptive learning (IL). We investigated if stress facilitates IL. Seventy-three healthy participants performed a heartbeat counting task (HCT: T1) and a heartbeat perception training (HBPT). After exposure to a socially-evaluated cold pressor stress test (SECPT; n = 48) or a control condition (n = 25), two more HCTs were performed (T2: 30 min after SECPT; T3: 24 h later). After the HBPT, all participants showed an increase in IAc. We separated the stress group into high vs. low systolic blood pressures (SB…
Systolic Blood Pressure Variation and Mean Heart Rate Is Associated With Cognitive Dysfunction in Patients With High Cardiovascular Risk
2015
Abstract— Elevated systolic blood pressure (SBP) correlates to cognitive decline and incident dementia. The effects of heart rate (HR), visit to visit HR variation, and visit to visit SBP variation are less well established. Patients without preexisting cognitive dysfunction (N=24 593) were evaluated according to mean SBP, SBP visit to visit variation (coefficient of variation [standard deviation/mean×100%], CV), mean HR, and visit to visit HR variation (HR-CV) in the Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial and the Telmisartan Randomized Assessment Study in ACE Intolerant Subjects with Cardiovascular Disease. Cognitive function was assessed with min…
Genomic and metabolomic profile associated to microalbuminuria.
2013
To identify factors related with the risk to develop microalbuminuria using combined genomic and metabolomic values from a general population study. One thousand five hundred and two subjects, Caucasian, more than 18 years, representative of the general population, were included. Blood pressure measurement and albumin/creatinine ratio were measured in a urine sample. Using SNPlex, 1251 SNPs potentially associated to urinary albumin excretion (UAE) were analyzed. Serum metabolomic profile was assessed by 1H NMR spectra using a Brucker Advance DRX 600 spectrometer. From the total population, 1217 (mean age 54 ± 19, 50.6% men, ACR>30 mg/g in 81 subjects) with high genotyping call rate were ana…
