Docosahexaenoic acid, but not eicosapentaenoic acid, lowers ambulatory blood pressure and shortens interval QT in spontaneously hypertensive rats in …

2009

International audience; This study was designed to evaluate the effects of individual dietary long-chain n-3 polyunsaturated fatty acids (LCPUFA) on hypertension and cardiac consecutive disorders in spontaneously hypertensive rats (SHR) as compared to Wistar-Kyoto rats (WKY). Rats were fed for 2 months an eicosapentaenoic (EPA)- or docosahexaenoic acid (DHA)-rich diet (240 mg/day) or an n-3 PUFA-free diet. Male SHR (n=6), implanted with cardiovascular telemetry devices, were housed in individual cages for continuous measurements of cardiovascular parameters (blood pressure (BP) and heart rate (HR)) during either activity or rest periods, ECG were recorded during the quiet period. The n-6 PU…

Global electrical heterogeneity as a predictor of cardiovascular mortality in men and women

2018

Aims The aim of this study was to investigate the contribution of depolarization and repolarization abnormalities, specially abnormalities in global electrical heterogeneity of heart in cardiovascular disease (CVD) and all-cause mortality. Methods and results Eight hundred and forty men and 911 women, average age of 63 years participated in this study with average follow-up was 14 years. Six electrocardiogram/vector electrocardiogram (ECG/VECG) markers QRS-duration, QTc-interval, QRST-angle, sum of absolute QRST integral (SAI QRST), T-wave roundness, and TV1-amplitude were estimated from VECG measurements. Hazard ratios (HRs) for CVD events (164 deaths) and all-cause mortality (383 deaths) …

Cryptogenic stroke and atrial fibrillation in a real-world population: the role of insertable cardiac monitors

2020

AbstractThe incidence of atrial fibrillation (AF) in cryptogenic stroke (CS) patients has been studied in carefully controlled clinical trials, but real-world data are limited. We investigated the incidence of AF in clinical practice among CS patients with an insertable cardiac monitor (ICM) placed for AF detection. Patients with CS admitted to our Stroke Unit were included in the study; they received an ICM and were monitored for up to 3 years for AF detection. All detected AF episodes of at least 120 sec were considered. From March 2016 to March 2019, 58 patients (mean age 68.1 ± 9.3 years, 67% male) received an ICM to detect AF after a CS. No patients were lost to follow-up. AF was detec…

The total absence of atrial automaticity in a child with sinus node dysfunction

2007

Background A routine sports evaluation identified constant alternation between a junctional and idioventricular rhythm in a 9-year-old child. During exercise testing, electrography demonstrated that the child was in junctional rhythm without any apparent P waves, and had a reduced increase in heart rate. Endocardial atrial pacing captured the atrium and demonstrated that atrioventricular conduction was normal, but the recovery time of the ectopic rhythm was very long. Three-dimensional electrophysiological mapping revealed 1:1 retrograde homogeneous conduction through the right atrium. Investigations Electrocardiography, Holter monitoring, echocardiography, exercise stress testing, atrial p…

Timing of percutaneous coronary intervention in troponin-negative patients with acute coronary syndrome without persistent ST-segment elevation: prel…

2015

OBJECTIVE Management of acute coronary syndromes without persistent ST-segment elevation (NSTE-ACS) and unstable angina pectoris (UAP) remains challenging. The study aimed to analyze the current management of UAP patients in German chest pain units focussing on the different time lines of invasive strategy. METHODS A total of 1400 UAP patients admitted to a certified chest pain unit were enrolled. Analyses of high-risk criteria with indication for invasive management and of 3-month clinical outcomes were performed by subgrouping UAP patients to immediate and early invasive (<8 hours), early elective invasive (8-24 hours), late elective invasive (24-72 hours) strategy, and without percutaneo…

Relationship between low lymphocyte count and major cardiac events in patients with acute chest pain, a non-diagnostic electrocardiogram and normal t…

2008

Risk stratification of patients with acute chest pain, non-diagnostic electrocardiogram and normal troponin (ACPneg) remains a challenge, partly because no standardized set of biomarkers with prognostic ability has been identified in this population. Lymphopenia has been associated with atherosclerosis progression and adverse outcomes in cardiovascular diseases; although its prognostic value in ACPneg is unknown. We sought to determine the relationship between the lymphocyte count obtained in the Emergency Department (ED) and the risk of the long-term all-cause mortality or myocardial infarction (MI) in patients with ACPneg.We analyzed 1030 consecutive patients admitted with ACPneg in our i…

[Relationship of C-reactive protein levels with angiographic findings and markers of necrosis in non-ST-segment elevation acute coronary syndrome].

2004

The mechanism responsible for elevated C-reactive protein levels (inflammation of the ruptured atherosclerotic plaque or myocardial necrosis) in acute coronary syndromes is controversial. The aim of this study was to investigate the relationship between C-reactive protein levels and angiographic complexity of the culprit lesion and troponin elevation in patients with non-ST elevation acute coronary syndromes.The study group consisted of 125 patients with single-vessel disease. Troponin-I and C-reactive protein were measured, and the complexity of the culprit lesion was analyzed (TIMI flow and thrombus). Information on age, sex, smoking habit, hypertension, hypercholesterolemia and diabetes …

Resistin, acute coronary syndrome and prognosis results from the AtheroGene study

2006

Resistin, an adipocyte and macrophage derived cytokine, causes insulin resistance and glucose intolerance. We investigated the impact of resistin as a diagnostic marker in patients with acute coronary syndrome and its prognostic value for future cardiovascular events.Resistin levels were determined in 1153 patients with stable angina (SAP), 380 patients with unstable angina, 278 patients with non-ST-elevation myocardial infarction (NSTEMI) and 111 patients with ST-elevation myocardial infarction (STEMI). All patients have been followed up for a median follow-up of 2.6 years. During follow-up, 70 patients died from cardiovascular causes.Compared to SAP, resistin levels (5.1 ng/mL in SAP) wer…

Prognosis and Management of Acute Coronary Syndrome in Spain in 2012: The DIOCLES Study

2015

Abstract Introduction and objectives To identify the current mortality and management of patients admitted for suspected acute coronary syndrome in Spain. The last available registry (2004-2005) reported an in-hospital mortality of 5.7%. Methods The study included patients consecutively admitted between January and June 2012 at 44 hospitals selected at random. Information was collected on clinical course at admission and on events at 6 months. Results A total of 2557 patients admitted with suspected acute coronary syndrome were included: 788 (30.8%) with ST-segment elevation, 1602 (62.7%) without ST-segment elevation, and 167 (6.5%) with unclassified acute coronary syndrome. In-hospital mor…
