Abstract
In order to determine the role of two polymorphisms in the factor VII gene (R353Q and intron 7 hypervariable region) in the susceptibility to develop early myocardial infarction, a total of 175 patients with acute myocardial infarction aged 50 years or less (mean age 41+/-7 years) and 200 controls (average age 42+/-6) without cardiovascular disease were genotyped for these polymorphisms. Gene and genotype frequencies did not differ between patients and controls. Although the 353-QQ genotype was at a higher frequency among controls (4%) compared to patients (1%), the difference did not reach statistical significance. Carriers of the H7-allele (intron 7 polymorphism) were at a slightly higher frequency among patients (51 vs. 43%; P=0.19; OR=1.36; 95% CI=1.09-1.70). Our data suggest a lack of association between both polymorphisms in the factor VII gene and early myocardial infarction in our population.

Abstract
DNA polymorphisms at the endothelium constitutive nitric oxide synthase gene (NOS3) have been linked to the risk of developing coronary artery disease (CAD). In vitro, a polymorphism in the 5' region of the NOS3 gene (-786 T/C) influences promoter activity. This polymorphism has been associated with coronary spasms among Japanese. The genetic variation at the angiotensin-converting enzyme (ACE) is associated with plasma ACE activities and has also been linked with susceptibility to cardiovascular disease. Our objective was to determine if DNA polymorphisms in the NOS3 and ACE genes were associated with early CAD. We analyzed the -786 T/C polymorphism in the 5' flanking region and the 27-bp repeat polymorphism in NOS3 intron 4, as well as the ACE-I/D polymorphism. A total of 170 male smokers (CAD patients) younger than 50 years and 300 male smokers (healthy controls) were genotyped. Frequencies were compared by the chi(2) test, and odds ratios (ORs) and their 95% confidence intervals (CI) were also calculated. Only the -786 T/C polymorphism in the 5' flanking region of the NOS3 gene was significantly associated with early CAD in our population. The frequency of the CC genotype was significantly increased (P = 0.039) in patients compared to controls (OR = 1.67; 95% CI = 1.01, 2.72). We found a synergistic effect between the NOS3-CC and the ACE-DD genotypes in the risk of developing early CAD. The frequency of CC + DD was significantly increased among patients (P = 0.002). Thus, those with a NOS3-CC and an ACE-DD genotype would have a significantly increased risk of suffering an early episode of coronary artery disease (OR = 2.82; 95% CI = 1.40, 5.70). Although based on a limited number of patients, our work suggests that individuals who are NOS3-CC + ACE-DD are at a higher risk for early CAD, probably as a consequence of increased endothelial dysfunction.

Abstract
Our objective was to examine the association between myocardial infarction (MI) and two DNA-polymorphisms at the proinflammatory chemokine receptors CCR2 (I64V) and CCR5 (32 bp deletion, (Delta)ccr5), defining if these polymorphisms influence the age for the onset of MI. A total of 214 patients with an age at the first MI episode <55 years, 96 patients that suffered the first MI episode when older than 60 years, and 360 population controls were polymerase chain reaction genotyped for the CCR2-V64I and CCR5-Delta32/wt polymorphisms. Patients and controls were male from the same Caucasian population (Asturias, northern Spain). The frequency of the Deltaccr5 allele was significantly higher in controls compared to patients <55 years (P = 0.004), or in patients >60 years compared to patients <55 years (P = 0.002). Taking the patients >60 years as the reference group, non-carriers of the (Delta)ccr5-allele would have a three-fold higher risk of suffering an episode of MI at <55 years of age (OR = 3.06; 95% CI = 1.46-6.42). Gene and genotype frequencies for the CCR2 polymorphism did not differ between patients <55 years and controls or patients >60 years. Our data suggest that the variation at the CCR5 gene could modulate the age at the onset of MI. Patients carrying the (Delta)ccr5-allele would be protected against an early episode of MI. CCR5 and the CCR5-ligands are expressed by cells in the arteriosclerotic plaque. Thus, the protective role of (Delta)ccr5 could be a consequence of an attenuated inflammatory response, that would determine a slower progression of the arteriosclerotic lesion among (Delta)ccr5-carriers. Our work suggests that the pharmacological blockade of CCR5 could be a valuable therapy in the treatment of MI.

Abstract
OBJECTIVE The aim of this study was to determine the incidence of adult congenital anomalies of the coronary arteries over 31 years of angiographic studies, describing their angiographic and clinical characteristics. The results have been compared with the main series published. METHODS The diagnostic angiographic reports done in the Principado de Asturias from 1968 to 1999 are reviewed. In those in which a congenital anomaly was diagnosed, the clinical report and the angiography were studied. The initial course of the anomaly was defined following angiographic criteria. RESULTS Thirteen thousand five hundred reports were reviewed describing 75 patients with 75 anomalies (0.5%) including: anomalous origin of the left circumflex coronary artery (n = 24), coronary artery fistulae (n = 21), both coronary arteries arising from the left coronary sinus (n = 15), single coronary arteries (n = 6), both coronary arteries arising from the right coronary sinus (n = 2), separated origin of anterior descending and left circumflex coronary arteries (n = 3), anterior descending artery arising from the right coronary sinus (n = 2), and others (n = 1). Angiographic studies were done because of: angina (59%), dysnea (25%), atypical chest pain (7%), syncope (3%), dizziness (3%) and palpitations (3%). The initial course was retroaortic in all the circumflex arteries, interarterial in the right coronaries, anterior in the anterior descending arteries and retroaortic, septal and combined, in the left coronaries. CONCLUSIONS Adult congenital anomalies of the coronary arteries are not very common and are usually casual findings of diagnostic angiographic studies. Left circumflex coronary artery anomalies are the most frequently diagnosed.

Abstract
BACKGROUND Several studies based on different populations worldwide have described an association between cardiovascular diseases and genetic variations in the apolipoprotein E (A:POE), angiotensinogen (A:GT), angiotensin receptor type 1 (A:T1R), and angiotensin-converting enzyme (A:CE) genes. In addition, there is growing evidence of an interaction between hypercholesterolemia and the renin-angiotensin system in the risk for hypertension and atherosclerosis. METHODS To determine whether the DNA polymorphisms in A:POE (epsilon2, epsilon3, and epsilon4 alleles), A:GT (M235T), A:T1R (1166 A:/C:), and ACE (I:/D:) are associated with early onset of myocardial infarction (MI), we genotyped 220 patients and 200 controls <55 years of age. Patients and controls were males from the same homogeneous Caucasian population. Data concerning hypertension, diabetes, and tobacco consumption were recorded. The lipid profiles of patients and controls were also determined. RESULTS APOE, ACE, AGT, and AT1R allele and genotype frequencies did not differ between patients and controls. None of these polymorphisms was related to the biochemical values in patients or controls. The frequency of individuals who were both APOE epsilon4 allele carriers and AGT-TT homozygotes was significantly higher in patients than in controls (11% vs 3.5%; P: = 0.0037). In patients, the frequency of epsilon4 carriers was significantly higher (P: <0.00001) in those who were AGT-TT (46%) than those who were AGT-MT/MM (14%). Mean cholesterol was significantly higher in AGT-TT + APOE epsilon34/44 patients than in the TM/MM + epsilon34/44 or TT + epsilon23/33 genotypes (P: = 0. 029). CONCLUSIONS Our data suggest a synergistic effect between the APOE and AGT polymorphisms and early MI. The increased risk could be mediated in part through higher cholesterol concentrations among individuals who are AGT-TT + APOE epsilon4 allele carriers.

Abstract
The D allele at the angiotensin-I-converting enzyme (ACE)-insertion/deletion polymorphism has been associated with an increased risk of developing several pathological processes, such as coronary heart disease and ventricular hypertrophy. Individuals with the DD genotype show a significantly increased left-ventricular mass in response to physical training, compared to the II genotype (which would be associated with the lowest plasma ACE levels) and the ID genotype. The II genotype has been linked to a greater anabolic response. In accordance with a role for ACE in the response to rigorous physical training, a higher frequency of the I allele has been reported to exist among elite rowers and high-altitude mountaineers. Sixty elite (professional) athletes (25 cyclists, 20 long-distance runners, and 15 handball players), and 400 healthy controls were genotyped for the DNA polymorphisms of the ACE, angiotensinogen (Ang) and angiotensin receptor type 1 (AT1) genes. Plasma ACE levels showed a strong correlation with the I/D genotype in our population. The I-allele occurred at a significantly higher frequency in athletes compared to controls (P = 0.0009). Gene and genotype frequencies for the Ang and AT1 polymorphisms did not differ between athletes and controls. Since the frequency of the ACE I allele was significantly increased among our elite athletes, we conclude that the ACE polymorphism represents a genetic factor that contributes to the development of an elite athlete.

Abstract
The author examines how Bioethics should be approached in a pluralist society. She argues that through the gradual discovery of shared ethical values and principles for judging which practices are humanizing and which or not, ever-more dense civil Bioethics helps bring out--in contrast to relativism and subjectivism--an ethical intersubjectiveness, the fundaments of which should be addressed by moral philosophy if it hopes to fulfill one of its main tasks.

Abstract
This study was performed in order to establish the role of the prothrombin 20210 G/A and factor V Leiden (R506Q) polymorphisms in the susceptibility to develop venous thromboembolism and early coronary artery disease (CAD). These polymorphisms were determined in 82 consecutive patients with venous thromboembolism, 175 male patients with early CAD, and 200 healthy controls from the same Caucasian population (Asturias, Northern Spain). DNA was amplified using polymerase chain reactions and digested with the appropriate restriction enzymes in order to define the prothrombin and factor V genotypes. The prevalence of the heterozygous for the prothrombin A allele was 3.5% in the general population and 15.8% in patients with venous thrombosis (P = 0.0007); the frequency was 4% in patients with early CAD. No sex-related differences in the prevalence of the A allele were observed, and the average age at the first venous thromboembolic event was similar between GG and AG patients. The frequency of carriers of the factor V Leiden polymorphism was 9.75% among patients with venous thromboembolism, compared with 3.5% among controls, and 3.4% in the patients with CAD. Our data showed an association between venous thromboembolism and the AG genotype at the prothrombin 20210 G/A polymorphism. This polymorphism was not related to an increased risk for early CAD in our population of male patients.

Genetic studies have identified polymorphisms at the apolipoprotein (Apo) A1 gene associated with HDL cholesterol and apolipoprotein levels, and a relationship between the severity of coronary artery disease and polymorphisms at the 5'-end of Apo A1 has been also reported. This study was designed to examine the relationship between polymorphism at the Apo A1 gene and the risk of early coronary artery disease. Furthermore, the association of the polymorphism with the classical risk factors was analyzed. A total of 176 male patients (mean age 43 +/- 5 years) diagnosed as having unstable angina (53 cases) or myocardial infarction (123 cases) were prospectively evaluated. Data referring to hypertension, diabetes and tobacco consumption were recorded. The levels of total cholesterol, HDL cholesterol, Apo A1 and B and triglycerides were determined. DNA was obtained from the 176 patients and from 200 controls. In order to determine the Apo A1 genotypes at two polymorphic sites (G/A at -75 bp, and C/T at +83 bp), DNA was PCR amplified and digested with MspI. The frequency of carriers of the rare allele at the -75 bp site (M1-) was 0.34 in cases and 0.24 in controls (p < 0.05). The frequencies of the M1- allele among patients with angina and myocardial infarction were 0.43 (p = 0.009, angina vs. controls) and 0.30, respectively. No significant association between this polymorphism and other cardiovascular risk factors was found. No difference in the frequencies for carriers of the rare allele at the +83-bp polymorphism (M2) was observed among patients with angina (0.08 vs. 0.07) or myocardial infarction (0.04 vs. 0.07), and no association between this polymorphism and tobacco, hypertension and diabetes was noted. Patients carrying the rare M2- allele had a lower concentration of total cholesterol compared to those without this allele (183 +/- 29 vs. 223 +/- 54, p < 0.04) and HDL cholesterol was also lower among patients carrying the M2- (26 +/- 4 vs. 33 +/- 9, p < 0.02). In our community male patients with a diagnosis of coronary artery disease and age less than 50 years showed a higher frequency of the M1- allele at the -75-bp site of the Apo A1 gene. There was a significant increase in the frequency of the M1- allele in patients with unstable angina and no association with risk factors. In the +83-bp polymorphism there was no difference in the allelelic frequencies or the risk factors, except for the HDL cholesterol and total cholesterol where the patients with the allele M2- had lower levels than those homozygous for the M2+.

Abstract
OBJECTIVE To examine the association between coronary artery disease and polymorphisms at the angiotensin-converting enzyme (ACE) and angiotensin II type 1 receptor (AT1R) genes. METHODS A total of 181 patients younger than 50 years and 240 controls from the same homogeneous Caucasian population (Asturias, Northern Spain) were genotyped (using polymerase chain reaction) for the ACE insertion/deletion (ACE-I/D) and the AT1R A/C transversion (AT1R-A/C) (3-untranslated region) polymorphisms. RESULTS The DD-genotype was at a non-significant higher frequency among patients (50%) than in controls (41%). No difference between the two groups was found for the AT1R-genotypes. Distribution of ACE-genotypes according to AT1R-genotypes showed a significant association between ACE-DD and AT1R-CC and early coronary disease. Among the CC patients 58% were DD, compared to 21% among the controls (p = 0.02; OR = 5.32, 95% CI = 1.45, 19.51). We determined the distribution of these genotypes among the hypertensive and non-hypertensive patients. Frequencies of ACE- or AT1R-genotypes did not differ between the two groups. However, we found an interaction between the DD- and CC-genotypes in the group of normotensives. Among the CC patients, 13% of the hypertensives and 75% of the normotensives were DD (p = 0.014). CONCLUSIONS Our results indicate a synergistic contribution of ACE and AT1R polymorphisms to the risk of coronary artery disease. This gene-gene interaction could have clinical implications. Approximately 2% of individuals in our population are CC + DD, and the genotyping of both polymorphisms could identify those with a high relative risk for coronary artery disease.

Abstract
Takayasu arteritis has been recognized in Colombia just recently, and so far we do not have any report concerning its presentation here. In this first report, some issues related to the presentation of the disease are indicated and compared with those found in the medical literature. No differences were found in age and sex. Most of the cases were diagnosed during an inactive phase of the disease with advanced manifestations due to vascular lesion which suggests the existence of some genetic factor influencing such a presentation, or may be the consequence of a delay in diagnosing the disease during initial and active stages due to not suspecting it. Comparing the vessels which are affected among other races and countries, we can find both differences and similarities. With the purpose of discovering the demographic, clinical, angiographic and laboratorial characteristics of Takayasu arteritis in Colombia, the present study was carried out by studying 35 clinical cases in different medical centers of the country.

Abstract
We report the cases of three young men, heavy smokers, without previous heart disease and who were resuscitated after cardiac arrest due to ventricular fibrillation attributed to coronary spasm. All of them complained of atypical chest pain and the exercise testing, echocardiogram and coronary angiography were normal. The first case was diagnosed by Holter monitoring and by provocative testing with intracoronary ergonovine; the second by provocative testing with intracoronary acetylcholine and the third by Holter monitoring. The patients were treated with a calcium antagonist and/or nitrates and in the follow up they remained asymptomatic.

Abstract
BACKGROUND Drugs that improve symptoms in patients with heart failure must also be assessed for their effects on survival. Ibopamine stimulates DA-1 and DA-2 receptors and causes peripheral and renal vasodilatation; the drug improves symptoms of heart failure. We assessed the effect of ibopamine on survival in patients with advanced heart failure in a multicentre, randomised placebo-controlled study. METHODS Patients with advanced severe heart failure (New York Heart Association classes III and IV) and evidence of severe left-ventricular disease, who were already receiving optimum treatment for heart failure, were randomly allocated oral ibopamine 100 mg three times daily or placebo. The primary endpoint was all-cause mortality. The study was designed to recruit 2200 patients, and the minimum duration of treatment would be 6 months. We did intention-to-treat and on-treatment analyses; a post-hoc subgroup analysis was also done. FINDINGS After we had recruited 1906 patients the trial was stopped early, because of an excess of deaths among patients in the ibopamine group. 232 (25%) of 953 patients in the ibopamine group died, compared with 193 (20%) of 953 patients in the placebo group (relative risk 1.26 [95% CI 1.04-1.53], p = 0.017). The average length of follow-up was 347 days in the ibopamine group and 363 days in the placebo group. In multivariate analysis, only the use of antiarrhythmic drugs at baseline was a significant independent predictor of increased fatality in ibopamine-treated patients. INTERPRETATION Ibopamine seems to increase the risk of death among patients with advanced heart failure who are already receiving optimum therapy, but the reasons for this increase are not clear. Our finding that antiarrhythmic treatment was a significant predictor of increased mortality in ibopamine-treated patients may be important, but exploratory analyses must be interpreted with caution.

Abstract
Unstable angina with a clinical duration of < 2 months is characterized angiographically by a high incidence of complex lesions. Some patients have ischemic rest pain syndromes of longer duration. Thus, we retrospectively analyzed, in blinded fashion, the clinical and angiographic findings in 52 patients with unstable angina of < 2 months' duration (group A), and compared the results with those of 32 patients with unstable angina of > 6 months' duration (group B). Group B had a greater number of diseased vessels and better collateral circulation, but had fewer eccentric lesions. There were no differences in age, left ventricular function, or history of prior myocardial infarction. Thus, chronic unstable angina is associated with more extensive coronary disease than unstable angina of shorter duration. The role of different anatomic substrata and collateral circulation is discussed.

Abstract
Aldosterone has been associated with the development of cardiac hypertrophy and a correlation has been found between levels of aldosterone and the degree of cardiac hypertrophy in hypertensive patients. Our study aimed to test the relation between physiologic cardiac hypertrophy and serum aldosterone in a group of highly trained cyclists. Determination of the left ventricular mass index (LVMI) was performed in a group of 40 professional cyclists by using Devereux's formula with correction for body surface area. After an overnight fast, blood samples were collected and serum aldosterone levels were measured using RIA. LVMI and serum aldosterone were intercorrelated using linear regression analysis. Twenty-three of the 40 cyclists (58%) presented an LVMI > 130 g.m-1 and the other 17 subjects (42%) presented an LVMI < 130 g.m-1. Serum aldosterone levels did not correlate with LVMI in either of the groups (LVMI > 130 g.m-1, r = -0.089; LVMI < 130 g.m-1, r = 0.146). The lack of correlation of this hypertrophy with serum aldosterone levels suggests that physiologic hypertrophy of the athlete's heart could be caused by a different stimulus to that seen in pathologic hypertrophy of hypertensives.

Abstract
The term athlete's heart refers to an increased left ventricular mass. Few studies have assessed the prevalence and normal upper limit of cardiac hypertrophy in highly trained cyclists and this was the aim of this study. A group of 40 professional road cyclists [mean age 26 (SD 3) years] who had participated in European competitions for 3-10 years, were evaluated at the beginning of the 1992-93 season. Evaluation included a clinical history and physical examination, one and two-dimensional echocardiography, 12-lead resting electrocardiogram and a graded exercise test. Determination of the left ventricular mass index (LVMI) was performed using Devereux's formula with correction for the body surface area. Systolic and diastolic blood pressure were measured at rest and at peak exercise. Of the group 23 cyclists (58%) presented a LVMI greater than 130 g.m-2, 21 cyclists presented a diastolic ventricular thickness equal to or greater than 13 mm, with a superior limit of 19 mm; 3 cyclists presented asymmetrical septum hypertrophy; and the relationship between posterior wall and left ventricular diastolic radius was equal to or greater than 0.45 in 14 cases (35%). Electrocardiographic abnormalities of ST-T segment were seen in only 1 subject. No correlation was found between the degree of ventricular hypertrophy and arterial blood pressure. We concluded that these professional cyclists showed a high prevalence of cardiac hypertrophy (58%). The distribution of this hypertrophy was concentric in 20/33 and asymmetric in 3/23 of the subjects with left ventricular hypertrophy. The electrocardiograms were normal in 98% of the subjects.

Abstract
Lipoprotein(a) [Lp(a)] had been shown to be a strong independent risk factor for ischaemic heart disease. Our aim was to investigate the relationships between Lp(a) and other cardiovascular risk factors. 423 male miners (age 40 +/- 8 years) were analysed according to the following variables: age, arterial blood pressure, alcohol and cigarette consumption, total cholesterol and Lp(a). Analysis of the data was performed using the Kruskal-Wallis and Spearman tests. Analysis of variance showed statistical differences in Lp(a) levels with cigarette consumption (p < 0.02) and age (p < 0.001). No differences with corrected total cholesterol, blood pressure and alcohol consumption were found. Lp(a) and total cholesterol were correlated (p < 0.0001), but after correction for the estimated contribution of Lp(a) cholesterol this significant correlation disappeared. We conclude that male smokers have significantly lower Lp(a) values than non-smokers and those who quit. Our findings suggest that cigarette consumption is a probable environmental factor that might influence Lp(a) levels.

Abstract
The long-term follow-up of 35 patients with mean age of 74.3 +/- 8 years (64-86) who underwent percutaneous aortic valvuloplasty (PAV) is presented. The mean duration of the follow-up study was 33 months (range 1-48). Global mortality was 42% (14 patients) and was related to post-PAV aortic valvular area (47% mortality in less than 0.7 cm2 area group vs 28% in greater than or equal to 0.7 cm2 group) and left ventricular ejection fraction (67% in EF less than 35% group vs 35% in EF greater than or equal to 35% group). The actuarial probability of remaining alive and free of symptoms and of cardiac surgery or new PAV was 57, 41, 33, and 20% at 1, 2, 3 and 4 years. After PAV clinical improvement was obtained in most of the patients (68%), but only 42% of those with successful dilatation remain asymptomatic after a 24 months period (85 +/- 28 mmHg, p = NS). Transvalvular gradient studied by Doppler decreased immediately after PAV (92.8 +/- 26 mmHg vs 51 +/- 16 mmHg, p less than 0.001), but returned to baseline values after 12 months. These results show that PAV yields a clinical improvement in most of the patients, but this improvement is transitory, does not modify the natural history of the disease and has a high degree of restenosis. Thus, its use must be limited to a reduced group of patients who are not candidates for cardiac surgery.

Abstract
A case of calcificated intramyocardiac hydatid cyst is presented. The initial diagnosis was coronary artery disease and the onset was chest pain and typical abnormalities of the electrocardiogram. The diagnosis of hydatid disease was suspected from chest roentgenogram and confirmed by two-dimensional echocardiography and left ventriculography. Coronary arteriography was normal and surgical treatment successfully carried out.
