Utilidad de la troponina I para predecir la disfunción sistólica en los síndromes coronarios agudos. Resultados de un estudio prospectivo y cuantitat…
2003
The relationship between troponin I and systolic function (quantitative contrast ventriculography) was evaluated in 137 consecutive patients with a first acute coronary syndrome (60 with and 77 without ST elevation). In general, a larger troponin I peak value was related with a more depressed ejection fraction and poorer regional systolic function (p < 0.0001). Nevertheless, this correlation was weaker than expected, especially in those cases without ST-segment elevation, suggesting that other factors apart from systolic dysfunction must be taken into account in order to explain the worse prognosis of those patients with increased serum levels of this marker of myocardial damage.
Pronóstico a corto plazo de los pacientes ingresados por probable síndrome coronario agudo sin elevación del segmento ST. Papel de los nuevos marcado…
2002
Objectives. The relative value of classic markers, myocardial damage variables, and levels of acute-phase reactants in establishing the pre-discharge prognosis of acute coronary syndrome without ST-segment elevation was analyzed. Method. We prospectively studied 385 consecutive patients admitted from our chest pain unit with a highprobability diagnosis of acute coronary syndrome without ST-segment elevation. The clinical and electrocardiographic data, myocardial damage markers (troponin I, CK-Mb mass, myoglobin), and acute-phase reactants (high-sensitivity C-reactive protein, fibrinogen) were recorded. Results. During admission, 15 deaths (3.9%) and 16 complicative infarctions (4.2%) occurr…
Why does C-reactive protein increase in non-ST elevation acute coronary syndromes?
2003
Abstract Introduction: C-reactive protein is an important prognostic indicator for early risk stratification in patients with an acute coronary syndrome. The mechanisms underlying the elevation of C-reactive protein in these patients have not been fully understood. We studied the factors related to the increase of this acute-phase reactant. Methods and Results: Within a single-centre registry, 419 consecutive patients admitted for a non-ST elevation acute coronary syndrome were studied. Serum high sensitivity C-reactive protein was measured late (median 3 days) after admission. Clinical, electrocardiographic, biochemical and angiographic variables were recorded. In the multivariate analysis…
Impact of Frailty and Other Geriatric Syndromes on Clinical Management and Outcomes in Elderly Patients With Non-ST-Segment Elevation Acute Coronary …
2016
The incidence of acute coronary syndromes (ACS) is high in the elderly. Despite a high prevalence of frailty and other aging-related variables, little information exists about the optimal clinical management in patients with coexisting geriatric syndromes. The aim of the LONGEVO-SCA registry (Impacto de la Fragilidad y Otros Sindromes Geriatricos en el Manejo y Pronostico Vital del Anciano con Sindrome Coronario Agudo sin Elevacion de Segmento ST) is to assess the impact of aging-related variables on clinical management, prognosis, and functional status in elderly patients with ACS. A series of 500 consecutive octogenarian patients with non-ST-segment elevation ACS from 57 centers in Spain …
Anomalous Origins of the Left Main Coronary Artery From the Noncoronary Sinus and of the Right Coronary Artery From the Left Sinus of Valsalva
1997
A 70-year-old man was referred for recent-onset angina. The ECG showed a right-axis deviation and signs of an old anterior infarction with loss of R waves in leads V1 through V5. Chest radiograph demonstrated a markedly enlarged heart, which was shifted to the left side with discrete signs of pulmonary congestion. Transthoracic echocardiography, which was limited by poor imaging quality, revealed a normal left ventricular cavity with reduced ejection fraction (40%) due to hypokinesia of the anterior wall. Coronary angiography showed the dominant RCA to originate from the left sinus of Valsalva. It coursed between the aorta and the pulmonary artery to the right (Figs …
Do We Still Need Organic Nitrates?⁎⁎Editorials published in the Journal of the American College of Cardiologyreflect the views of the authors and do …
2007
Organic nitrates are still quite frequently used for the treatment of acute and chronic angina, and acute and chronic congestive heart failure. When given acutely, their effectiveness is undisputable; however, their long-term efficacy is substantially limited due to the development of tolerance ([1
Role of Nitrates for the Therapy of Coronary Artery Disease Patients in the Years beyond 2000
1999
Vasodilator therapy with nitrates has been used for almost a century to bring relief to patients suffering from angina. The acute anti-ischemic effects of nitro-vasodilators for the treatment and prevention of anginal attacks is unquestioned. In addition, nitrates are administered in order to reduce symptomatic and silent ischemic episodes, in patients with proven coronary heart disease who exert ST segment alterations on Holter monitoring. The reduction in total ischemic burden may result in an improved prognosis with regard to infarct prevention and possible prevention of deterioration of left ventricular function due to repetitive episodes of myocardial ischemia. In patients with unstabl…
Impact of cone-beam computed tomography for the identification and management of an oral portal of entry in patients with infective endocarditis. A D…
2021
Background Infective endocarditis (IE) is a rare and life-threatening disease. Cutaneous portal of entry (POE) is predominant for IE, but an oral POE is the second most frequent source. Thus looking for and treating an oral POE in IE patients is of critical importance in order to reduce the risk of IE relapse or recurrence. The objectives of this study were: 1) To reach a consensus on decision-making following the detection of an oral POE on cone-beam computed tomography (CBCT) while they were not identified using the current recommended approach in IE patients (oral examination and orthopantomogram: OPT). 2) To determine whether this consensus differs when regarding the microbiology of IE.…
Data-driven discovery of changes in clinical code usage over time: a case-study on changes in cardiovascular disease recording in two English electro…
2020
[EN] Objectives To demonstrate how data-driven variability methods can be used to identify changes in disease recording in two English electronic health records databases between 2001 and 2015. Design Repeated cross-sectional analysis that applied data-driven temporal variability methods to assess month-by-month changes in routinely collected medical data. A measure of difference between months was calculated based on joint distributions of age, gender, socioeconomic status and recorded cardiovascular diseases. Distances between months were used to identify temporal trends in data recording. Setting 400 English primary care practices from the Clinical Practice Research Datalink (CPRD GOLD) …
P1699Non-ST segment elevation miocardial infarction (NSTEMI) vs. Unstable angina (UA) in young women aged < 45 years - differences in symptomatolo…
2019
Abstract Background Almost 50% of all ACS in young women are NSTEMI and UA. Due to the type of ACS we observed differences in the symptomatology, treatment and outcomes. The aim was to evaluate the differences in the clinical course and prognosis in young women aged ≤45 years with NSTEMI vs. UA. Methods We compared 1143 women aged ≤45y.o. with acute cardiac syndromes: 51% NSTEMI, 49% UA from the PL-ACS registry between 2007 - 2014. Results Chest pain was predominant in both group, with a higher incidence in NSTEMI group (91.7% vs. 84.7, p=0.0002). UA group was older (42y.o. vs. 41y.o p=0.003), more often presents atypical symptoms (8.0% vs. 1.5%, p<0,0001) mostly with dyspnea (3.9%vs. 1.…
