Arrhythmia detection using an implantable loop recorder after a negative electrophysiology study in Brugada syndrome: Observations from a multicenter international registry.

Background: Risk stratification in Brugada syndrome (BrS) remains controversial. In this respect, the role of the electrophysiology study (EPS) has been a subject of debate. In some centers, it is common practice to use an implantable loop recorder (ILR) after a negative EPS to help in risk stratification.

Contemporary differences between men and women with acute coronary syndromes: CIAM multicenter registry.

Aim: Differences exist in the diagnosis and treatment of acute coronary syndrome (ACS) between men and women. However, recent advancements in the management of ACSs might have attenuated this sex gap. We evaluated the status of ACS management in a multicenter registry in 10 tertiary Spanish hospitals.

Compression of the right coronary artery by an aortic pseudoaneurysm after infective endocarditis: an unusual case of myocardial ischemia.

A 61-year-old male with a prosthetic St Jude aortic valve size 24 presented with heart failure symptoms and minimal-effort angina. Eleven months earlier, the patient had undergone cardiac surgery because of an aortic root dilatation and bicuspid aortic valve with severe regurgitation secondary to infectious endocarditis by and coronary artery disease in the left circumflex coronary artery. Then, a prosthesis valve and a saphenous bypass graft to the left circumflex coronary artery were placed.

Valve Calcification in Aortic Stenosis: Etiology and Diagnostic Imaging Techniques.

Aortic stenosis is the most common valvulopathy in the Western world. Its prevalence has increased significantly in recent years due to population aging; hence, up to 8% of westerners above the age of 84 now have severe aortic stenosis (Lindroos et al., 1993).

Bayes Syndrome and Imaging Techniques.

Interatrial block (IAB) is due to disruption in the Bachmann region (BR). According to whether interatrial electrical conduction is delayed or completely blocked through the BR, it can be classified as IAB of first, second or third degree. On the surface electrocardiogram, a P wave ≥ 120 ms (partial IAB) is observed or associated to the prolongation of the P wave with a biphasic (positive / negative) morphology in the inferior leads (advanced IAB).

[Prognostic value of serum homocysteine levels in elderly hospitalized patients].

Background And Objectives: Increased serum homocysteine levels are related to vascular disease and increased mortality. The decrease of homocysteine is also associated with a worse prognosis in patients on hemodialysis; however, this relationship has not been well studied in other patients. Our goal is to study the prognosis of increased and decreased serum homocysteine levels in elderly patients admitted to a general internal medicine unit.

Prognostic value of physical function tests: hand grip strength and six-minute walking test in elderly hospitalized patients.

To discern if physical function test are better mortality predictors than muscle mass in elderly hospitalized patients, we analyzed the prognostic value of muscle mass malnutrition and compared it with physical muscle function tests, including the six-minute walking test (6 MWT) and hand grip strength. We included the ankle brachial index (ABI) to assess arterial disease, related to muscle atrophy due to hypoperfusion. We also analyzed the relationship of ABI with malnutrition, physical function tests and survival.

Antioxidant vitamins and brain dysfunction in alcoholics.

Aims: Alcohol induces cytokine secretion by Kupffer cells, which may exert also deleterious effects on distant organs, mediated in part by cytokine-derived increased production of reactive oxygen species (ROS). It is therefore important to assess antioxidant levels. The objective of this study is to analyse the relation of antioxidant vitamins with brain atrophy and cognitive dysfunction.

Vitamin D and nutritional status are related to bone fractures in alcoholics.

Background: Bone fractures are common in alcoholics.

Aims: To analyse which factors (ethanol consumption; liver function impairment; bone densitometry; hormone changes; nutritional status, and disrupted social links and altered eating habits) are related to bone fractures in 90 alcoholic men admitted to our hospitalization unit because of organic problems.

Methods: Bone homoeostasis-related hormones were measured in patients and age- and sex-matched controls.

Prognosis of osteopenia in chronic alcoholics.

Osteoporosis is frequent among alcoholics all by a direct effect of ethanol, malnutrition, and liver failure. Therefore, it may be related to survival. The aim of this study was to assess bone mineral density (BMD), bone mineral content, hormonal status, and to determine prognostic value of these parameters in a total of 124 alcoholics followed up for a median period of 57 months.
