1. Does Mean Platelet Volume Decrease in the presence of Coronary Artery Fistula?
Resumo Fundamento: A fístula da artéria coronária (FAC) é uma conexão anormal que liga a artéria coronária a uma câmara cardíaca ou outro importante vaso sanguíneo. Vários estudos mostraram a associação entre o volume plaquetário médio (VPM) e as doenças cardiovasculares. Na literatura, não há estudo prévio sobre a associação entre os

2. Lack of a relationship between serum ferritin levels and coronary atherosclerosis evaluated by coronary arteriography
Many clinical and epidemiological studies have demonstrated the relationship between serum ferritin and ischemic heart disease. In the present study we evaluated the relationship between coronary heart disease (CHD) and serum ferritin levels in patients submitted to coronary arteriography. We evaluated 307 patients (210 (68.7%) males; median age: 60 years) w

3. Progressão da aterosclerose coronária avaliada pela coronariografia, em portadores de doença multiarterial submetidos a tratamento clínico, cirúrgico ou angioplastia / The progression of atherosclerotic coronary disease assessed by coronary arteriography in patients with multivessel coronary disease undergoing medicine, angioplasty, or surgery treatments
Introdução: Freqüentemente a progressão da doença coronariana aterosclerótica é observada por angiogramas seqüenciais e atribuída ao aumento da incidência de eventos coronarianos.O significado prognóstico desta progressão em pacientes randomizados e submetidos a diferentes formas terapêuticas ainda é pouco conhecido. Este estudo compara a progr

4. Selection of patients for myocardial perfusion scintigraphy based on fuzzy sets theory applied to clinical-epidemiological data and treadmill test results
Coronary artery disease (CAD) is a worldwide leading cause of death. The standard method for evaluating critical partial occlusions is coronary arteriography, a catheterization technique which is invasive, time consuming, and costly. There are noninvasive approaches for the early detection of CAD. The basis for the noninvasive diagnosis of CAD has been laid

5. "Definição de conduta na investigação de doença coronária obstrutiva utilizando teoria de conjuntos fuzzy aplicada a dados clínico-epidemiológicos, ergométricos e cintilográficos" / Establishment of diagnostic procedures for coronary artery disease based on fuzzy set theory applied to clinical epidemiological data and treadmill electrocardiography and myocardial perfusion scintigraphy results.
Coronary artery disease (CAD) is a worldwide leading cause of death. Early detection is important to prevent such sort of outcome. The gold standard method for evaluating critical partial occlusions is coronary arteriography, a catheterization technique which is invasive, time consuming, and costly. There are noninvasive approaches for early detection of CAD

6. Primary coronary angioplasty in a nonagenarian
A woman aged 98 years entered the tertiary hospital service with a picture of acute myocardial infarction of the extensive anterior wall, which began 4 hours earlier. Due to the large myocardial risk area suggested by the electrocardiogram, the patient was taken to the hemodynamics laboratory for the performance of emergency coronary arteriography, which rev

7. Noninvasive diagnosis of allograft vascular disease after heart transplantation
OBJECTIVE: To determine the predictive values of noninvasive tests for the detection of allograft vascular disease. METHODS: We studied 39 patients with mean ages of 48±13 years and a follow-up period of 86±13 months. The diagnosis of allograft vascular disease was made by cine-coronary arteriography, and it was considered as positive if lesions existed th

8. Tratamento endovascular de dissecção crônica toracoabdominal complicada com aneurisma torácico, mediante implante de endoprótese vascular
Our objective is to report a case of a patient with a descending thoracic aortic aneurysm and chronic aortic dissection, who was submitted to an endovascular treatment. A 68-year-old male with coronary artery disease and hypertension, with no history of trauma, diabetes or smoking. He had myocardial infarction ten years ago. Under general anesthesia, the lef

9. Do cardiologists have higher thresholds for recommending coronary arteriography than family physicians?
The purpose of this study was to use a new model of decision making to understand variability in physicians' utilization of diagnostic tests. We studied physicians' recommendations for coronary arteriography in hypothetical patients with chest pain by analyzing responses of 235 cardiologists and family physicians. Thresholds for testing were derived by obtai

10. Spontaneous coronary artery perforation with tamponade. Demonstration by necropsy selective coronary arteriography.
Pericardial tamponade in a 51-year-old man after acute anteroseptal myocardial infarction was the result of spontaneous perforation of an atheromatous coronary artery. The value of a simple necropsy technique of selective coronary arteriography in demonstrating the lesion is described.

11. Major complications of coronary arteriography: the place of cardiac surgery.
The records of the catheter laboratory at St George's Hospital between 1983-1988 were reviewed to determine how often emergency coronary bypass surgery was performed because of a complication arising during elective coronary arteriography. A total of 11,216 cardiac procedures were performed; 5781 were confined to left ventricular angiography and coronary art

12. Precurved catheters for transbrachial coronary arteriography1
A series of precurved catheters has been designed for use in coronary arteriography through the brachial artery. They facilitate entry of the coronary arteries, especially the left, from abnormal aortas. Their use has reduced the necessity for flushing the sinus of Valsalva as a method for viewing the coronary arteries, improved the quality of films obtained
