OBJECTIVES We examined the relationship between the angiotensinogen (AGT) gene M235T polymorphism, the variant promoter of the AGT gene A(-6)G and the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and coronary heart disease (CHD) in native Gran Canaria Island habitants, who have the highest rates of CHD in Spain.

BACKGROUND Apoptosis is a programmed cell death, genetically controlled, that can be activated by physiological and pathophysiological events and by the administration of several drugs, including the exogenous administration of corticosteroids. The aim of this study was to develop a rat model of intestinal lymphocytic apoptosis induced by dexamethasone to(More)
Fourteen cirrhotic patients with tense ascites were treated with total paracentesis and intravenous isotonic saline infusion. Standard liver and kidney function tests, plasma renin activity and aldosterone concentration were measured before, at 48 hrs and at 7 days after total paracentesis. The volume of ascites removed was 7.7 +/- 5.6 l (mean +/- S.E.M.).(More)
OBJECTIVES We sought to evaluate the usefulness of a comprehensive assessment of four cardiovascular magnetic resonance imaging (CMR)-derived myocardial viability indexes in the setting of myocardial stunning. BACKGROUND Cardiovascular magnetic resonance imaging allows the simultaneous assessment of several viability indexes. METHODS We studied 40(More)
The C677T transition of methylenetetrahydrofolate reductase (MTHFR) gene causes a moderate increase in total plasma homocysteine (tHcy). We studied the effect of MTHFR TT homozygosity and mild hyperhomocysteinemia on arterial hypertension. Normotensive controls (n = 223) and hypertensive subjects (n = 235) were matched for age, gender, and history of(More)
Antihypertensive drugs have differing effects on renal hemodynamics and morphology. We analyzed whether the use of a new beta adrenoceptor antagonist and vasodilator, carvedilol (CVD), slows the progression of nephrosclerosis and whether the renoprotective effect as well as reduction in cardiac hypertrophy is dependent on the degree of blood pressure(More)
AIMS We analyzed the usefulness of quantitative intravenous myocardial contrast echocardiography to study microvasculature perfusion after infarction in comparison with intracoronary myocardial contrast echocardiography. METHODS AND RESULTS Thirty-two patients with a first ST elevation myocardial infarction, single-vessel disease and an open artery (TIMI(More)
We have conducted a prospective double blind randomized and placebo controlled clinical study in 20 patients with shoulder pain syndrome caused by supraspinatus tendinitis to determine whether transdermal nitroglycerin (NTG) has analgesic action in this condition. In a randomized manner we used a 5-mg NTG (Nitroplast) patch per day over 3 days or similar(More)
INTRODUCTION AND OBJECTIVES An analysis was made of variability in the measurement of the angiographic index blush between a university hospital and an independent core laboratory, as well as its correlation with perfusion analyzed by intracoronary myocardial contrast echocardiography (MCE) and the ventricular function at the sixth month. METHODS The(More)
Premature babies < or = 35 weeks gestation, with or without chronic lung disease (CLD), and infants affected by severe congenital heart disease should be considered high risk population for RSV infection and hospitalization. Hygienic measures and RSV monoclonal antibodies (palivizumab) have been found useful in decreasing rates of RSV hospitalization in(More)
