[Is ICD-programming for double intraoperative defibrillation threshold energy safe and effective during long-time follow-up? Results of a prospective…
1999
The aim of this prospective and randomized study was to evaluate the safety and efficacy of a reduced shock strength in transvenous implantable defibrillator therapy. So far clinical data concerning the safety margin of the shock energy in ICD therapy do not exist. The shock energy tested during long-term follow-up in this study was twice the intraoperatively measured defibrillation threshold (DFT). A total number of 176 consecutive patients representing a typical cohort of ICD patients were evaluated. All patients received a non-thoracotomy lead system (CPI, Endotak 0070, 0090) and a biphasic cardioverter-defibrillator with the ability to store episodes (Cardiac Pacemakers Inc., Ventac TM …
Eficacia de la resincronización cardiaca en el tratamiento de la insuficiencia cardiaca sintomática: metaanálisis y análisis económico
2014
La insuficiencia cardiaca es un síndrome clínico crónico, causado por alteraciones funcionales del corazón, generalmente del ventrículo izquierdo (VI). Es un importante problema de salud, con unas elevadas morbilidad y mortalidad. Es una de las enfermedades cardiovasculares que causa más invalidez, más mortalidad y mayor gasto en los países de nuestro entorno, a pesar de los recientes avances en su tratamiento. La terapia de resincronización cardiaca es una opción terapéutica en estos enfermos. Se trata de un marcapasos tricameral, con electrodos localizados en aurícula derecha, ventrículo derecho y en cara lateral de ventrículo izquierdo. Logra corregir la asincronía electromecánica ventri…
Valor de la resonancia magnética con realce tardío de gadolinio en el diagnóstico etiológico de la insuficiencia cardiaca con disfunción sistólica de…
2013
La insuficiencia cardiaca constituye un problema de salud y de gestión de los recursos sanitarios de primer orden. Se estima que la prevalencia de insuficiencia cardiaca sintomática en la población general europea oscila entre el 0.4-2%. El diagnóstico preciso del síndrome de insuficiencia cardiaca por medios exclusivamente clínicos es dificultoso y muchas veces inadecuado sobre todo en mujeres, ancianos y obesos20. La insuficiencia cardiaca asociada a miocardiopatía dilatada idiopática o a miocardiopatía isquémica puede ser clínicamente indistinguible. Los síntomas de angina y los factores de riesgo generalmente asociados a la enfermedad coronaria no son exclusivos ni constantes, además, l…
Biomarcadores en hipertensión pulmonar de causa cardiaca izquierda. Valor diagnóstico y pronóstico.
2015
La hipertensión pulmonar (HP) debida a enfermedad del corazón izquierdo es una patología prevalente, grave y asociada a importante morbilidad y mortalidad, sobre todo cuando produce un deterioro de la función ventricular derecha. Dentro de esta enfermedad, existen varios tipos según la respuesta del lecho vascular pulmonar. Se asume que en la HP pasiva se inicia una disfunción endotelial que puede progresar hacia una hiperplasia vascular con grave repercusión sobre el ventrículo derecho y sin posibilidad de regresión. Actualmente, para el diagnóstico de HP es indispensable un cateterismo cardíaco derecho causante de morbilidad e incluso mortalidad. Lo que se pretende con este proyecto es in…
Cardiorenal Syndrome: New Pathways and Novel Biomarkers
2021
Cardiorenal syndrome (CRS) is a multi-organ disease characterized by the complex interaction between heart and kidney during acute or chronic injury. The pathogenesis of CRS involves metabolic, hemodynamic, neurohormonal, and inflammatory mechanisms, and atherosclerotic degeneration. In the process of better understanding the bi-directional pathophysiological aspects of CRS, the need to find precise and easy-to-use markers has also evolved. Based on the new pathophysiological standpoints and an overall vision of the CRS, the literature on renal, cardiac, metabolic, oxidative, and vascular circulating biomarkers was evaluated. Though the effectiveness of different extensively applied biomark…
Monitoring Risk Factors and Improving Adherence to Therapy in Patients With Chronic Kidney Disease (Smit-CKD Project): Pilot Observational Study
2022
Background Chronic kidney disease is a major public health issue, with about 13% of the general adult population and 30% of the elderly affected. Patients in the last stage of this disease have an almost uniquely high risk of death and cardiovascular events, with reduced adherence to therapy representing an additional risk factor for cardiovascular morbidity and mortality. Considering the increased penetration of mobile phones, a mobile app could educate patients to autonomously monitor cardiorenal risk factors. Objective With this background in mind, we developed an integrated system of a server and app with the aim of improving self-monitoring of cardiovascular and renal risk factors and…
Association between ideal cardiovascular health and risk of sudden cardiac death and all-cause mortality among middle-aged men in Finland
2021
Background Strong associations have been demonstrated between the American Heart Association’s cardiovascular health (CVH) metrics and various cardiovascular outcomes, but the association with sudden cardiac death (SCD) is uncertain. We examined the associations between these CVH metrics and the risks of SCD and all-cause mortality among men in Finland. Methods and results We used the prospective population-based Kuopio Ischaemic Heart Disease cohort study, which consists of men between 42 and 60 years of age at baseline. CVH metrics were computed for 2577 men with CVH scores at baseline ranging from 0 to 7, categorized into CVH scores of 0–2 (poor), 3–4 (intermediate) and 5–7 (ideal). Mult…
Sleep Duration and Risk of Fatal Coronary Heart Disease, Sudden Cardiac Death, Cancer Death, and All-Cause Mortality
2018
Background: Sleep duration has been shown to be associated with all-cause mortality, however its relationship with cause-specific fatal events remains uncertain. We examined the relationship between sleep duration and risk of fatal coronary heart disease (CHD), sudden cardiac death, cancer related death and all-cause mortality. Methods Sleep duration was self-reported at baseline examinations performed between March 20, 1984 and December 5, 1989 in 2,361 men aged 42-61 years old from the Kuopio Ischemic Heart Disease study. Of these 1734 (73.4%) men were free from CHD and cancer at baseline. Results: A total of 802 all cause deaths, 202 fatal coronary heart disease events, 141 sudden cardia…

Coronary artery fistulas: symptoms may not correlate to size. An emblematic case and literature review
2015
<p>Coronary artery fistulas are rare anatomic abnormalities of the coronary arteries present in 0.002% of the general population and represent 14% of all anomalies of coronary arteries. Their clinical relevance focuses mainly on the mechanism of "coronary steal phenomenon”, causing myocardial functional ischemia even in the absence of stenosis, hence common symptoms are angina or dyspnea. Small size fistulas are mostly asymptomatic and have excellent prognosis if managed medically with regular follow-up consisting also in echocardiography every 2-5 years. Big-sized and symptomatic fistulas, on the contrary, should undergo invasive closure, either with a transcatheter approach or with …
