[Adult congenital anomalies of the coronary arteries described over 31 years of angiographic studies in the Asturias Principality: main angiographic and clinical characteristics].

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.

[The etiology and associated risk factors in a sample of 300 patients with atrial fibrillation].

PURPOSE: To analyze the etiology and the prevalence of risk factors in patients with atrial fibrillation. PATIENTS AND METHODS: Applying an unpaired case controlled study, we examined 300 consecutive patients (143 men) with atrial fibrillation and a mean age of 66 +/- 8 years. This group is compared with a control group of 700 patients (mean age 64 +/- 12 years). RESULTS: In the group with atrial fibrillation the etiology in 32% was arterial hypertension, in 20% coronary heart disease, in 13% valvular heart disease, in 11% heart failure, in 4% hyperthyroidism and in 20% idiopathic. 50% presented hypertension, 29% tobaccoism, 26% left ventricular hypertrophy, 20% consumption of alcohol, 19% hypercholesterolemia and 16% diabetes. Compared with the control group, patients with atrial fibrillation had coronary heart disease (p < 0.05), VHD (p < 0.01), myocardiopathy (p < 0.05), HT (p < 0.001), left ventricular hypertrophy (p < 0.001), diabetes (p < 0.01) and alcohol consumption (p < 0.01) more frequently. In the multivariant analysis heart failure (odds ratio 2.1 [1.2-3.3]), the valvular heart disease (odds ratio 2.2 [1.4-3.5]), the coronary heart disease (odds ratio 1.8 [1.2-2.6]), the arterial hypertension (odds ratio 1.7 [1.2-2.3]), the left ventricular hypertrophy (odds ratio 2.6 [1.7-3.8]), the diabetes (odds ratio 1.9 [1.2-2.9]) and alcoholic habits (odds ratio 2 [1.3-3.9]) were independent risk factors for atrial fibrillation in our population. CONCLUSIONS: Atrial fibrillation in our study, is more frequent in patients with arterial hypertension, coronary heart disease or valvular heart disease. There are other risk factors such as arterial hypertension, diabetes and consumption of alcohol too, the modification of which could diminish the risk of the appearance of atrial fibrillation.

[Spontaneous echocardiographic contrast in the left ventricle: apropos of 2 cases].

Two cases of spontaneous echocardiographic contrast in the left ventricle, using transthoracic echocardiography, are presented. One is due to a low-flow state in a patient with a dilated myocardiopathy. In the other we observed the echogenicity of a turbulent intracardiac blood flow across a mitral prosthesis. We considered the different theories that tried to explain the multiple origin of this "smoke".

[Left coronary artery with anomalous origin and course].

We report a 45 year-old patient with angina and positive exercise test. In the coronary arteriography that left coronary artery rose from a vascular structure that connected the aorta to the middle of the left anterior descending coronary artery. In the right coronary artery there was a 90% stenosis. An ACTP was made in this stenosis. The patient displayed no symptoms eight months after the procedure. We have not found in the literature and anomaly of the left coronary artery similar to what was found in this patient.

[Restrictive cardiac involvement in a patient with dyserythropoietic anemia and secondary hemochromatosis].

We report a case of a 63 year old woman diagnosed with dyserythropoietic anemia who was admitted to our hospital with congestive heart failure. Iron's metabolism disturbance, CT-Scan and magnetic resonance imaging allowed us to make the diagnosis of acquired hemochromatosis due to multiple transfusions. The echocardiographic study was compatible with a myocardial restrictive pattern caused by iron deposits.

[Reversible dilated cardiomyopathy and hyperthyroidism].

Thyrotoxicosis may precipitate atrial fibrillation, myocardial ischemia or heart failure if underlying heart disease is present. However, reversible dilated cardiomyopathy is rare. We report a case of a 51-year-old man with thyrotoxicosis and dilated cardiomyopathy that was reversed with antithyroid treatment.

[A retroaortic anomalous left coronary artery].

We report a 67-years-old patient with angina pectoris and positive treadmill test. In the coronary arteriography the left coronary artery arose from the right coronary sinus of Valsalva through an independent ostium and followed a retroaortic course. Coronary artery disease was no demonstrated, so we thought that the myocardial ischaemia shown in the treadmill test, was due to the anomalous origin of the left coronary artery. Surgical treatment was recommended.

[Study of associated risk factors and prevalence of heart diseases in patients with arterial hypertension].

We studied the frequency of heart disease and association with other coronary risk factors in 243 consecutive patients (124 male and 119 female) suffering from arterial hypertension (Group HT). The mean age was 67.5 +/- 9.6 years. This group was compared to a group of 357 subjects (217 male and 140 female) without arterial hypertension (Group noHT) and mean age of 63.5 +/- 13 years. In our group the patients with arterial hypertension presented smoking habits in 35%, hypercholesterolemia in 22%, left ventricular hypertrophy (LVH) in 18%, alcoholic habits in 15%, hypertriglyceridemia in 12%, diabetes in 9% and hyperuricemia in 7%. 15% of the patients suffering from arterial hypertension turned out with coronary heart disease (62% angina and 38% myocardial infarction), 19% with atrial fibrillation and 13% with heart failure. Compared to the patients without hypertension we found significant statistical correlation with the age (67.5 +/- 9.6 HT and 63.5 +/- 13 no HT, p < 0.001), the LVH (18% HT and 4% no HT, p < 0.001) and number of coronary risk factors (2 +/- 1 HT and 1.1 +/- 0.9, p < 0.001). The percentage of people without cardiac disease is lower among the group with arterial hypertension (53% HT and 71% noHT, p < 0.001), showing as well a higher incidence of atrial fibrillation (19% HT and 11% noHT, p < 0.05) and heart failure (13% HT and 7% noHT, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
