1/746. Pericardial heart disease: a study of its causes, consequences, and morphologic features.This report reviews morphologic aspects of pericardial heart disease. A morphologic classification for this condition is presented. An ideal classification of pericardial heart disease obviously would take into account clinical, etiologic and morphologic features of this condition but a single classification combining these three components is lacking. Pericardial heart disease is relatively uncommon clinically, and when present at necropsy it usually had not been recognized during life. The term "pericarditis" is inaccurate because most pericardial diseases are noninflammatory in nature. Morphologically chronic pericardial heart disease may present clinically as an acute illness. Even when clinical symptoms are present, however, few patients develop evidence of cardiac dysfunction (constriction). When pericardial constriction occurs, it is the result of increased pericardial fluid or increased pericardial tissue or both. Increased fluid is treated by drainage; increased tissue is treated by excision. In most patients with chronic constrictive pericarditis the etiology is not apparent even after histologic examination of pericardia.- - - - - - - - - - ranking = 1keywords = heart disease, heart (Clic here for more details about this article) |
2/746. Coronary dissection and myocardial infarction following blunt chest trauma.Myocardial infarction (MI) following blunt chest trauma is rarely diagnosed because the ensuing cardiac pain is commonly attributed to contused myocardium or the traumatic injuries in the local chest wall. There are only scattered reports on the coronary pathology associated with MI secondary to blunt chest trauma. Because differentiation of the pathology is difficult but important, we report here three cases of acute anterior MI secondary to coronary dissection following blunt chest trauma. Coronary dissection was demonstrated by coronary angiography. Two of the patients had intimal tears at the proximal left anterior descending artery (LAD) with normal flow, and the other patient had nearly total occlusion of the LAD associated with filling defects probably caused by an intracoronary thrombus. All three patients received conservative treatment without major complications and remained free from angina or heart failure throughout a 5-year follow-up period. In order to exclude associated MI in cases of blunt chest trauma, electrocardiography is necessary, and coronary angiography may be indicated to demonstrate coronary arterial pathology. dissection of the coronary artery with subsequent thrombus formation is one of the possible pathophysiologic mechanisms of MI following blunt chest trauma.- - - - - - - - - - ranking = 0.053590249926418keywords = heart (Clic here for more details about this article) |
3/746. Myocardial infarction in patients with systemic lupus erythematosus with normal findings from coronary arteriography and without coronary vasculitis--case reports.The authors present the cases of two young patients, a man and a woman, who presented with myocardial infarction, in the absence of ischemic heart disease or stenosis of the coronary arteries. The woman was known to have systemic lupus erythematosus (SLE) for the past 3 years (the immunoglobulin m [IgM] anticardiolipins antibodies were positive), without a history of coronary risk factors. Suddenly she presented with acute chest pain on rest that lasted 4 hours and culminated in anterior wall myocardial infarction. She was admitted to the coronary care unit, where no thrombolysis was given. She did not have echocardiographic evidence of Libman-Sacks endocarditis, but myocardial infarction was evident at the electrocardiogram (ECG). The young man had SLE (the IgM anticardiolipins were absent, but he was positive for lupus anticoagulant antibodies), he was hyperlipidemic, was a moderate smoker and moderately obese, and had no history of ischemic heart disease. He suddenly presented with an acute myocardial infarction documented by ECG, enzymes, and gammagraphy. In both patients, coronary angiography findings were normal and myocardial biopsy did not show evidence of arteritis. The relevance of these cases is the rare association of ischemic heart disease in SLE, with normal coronary arteries and without evidence of arteritis or verrucous endocarditis.- - - - - - - - - - ranking = 0.375keywords = heart disease, heart (Clic here for more details about this article) |
4/746. The electrocardiographic diagnosis of acute myocardial infarction in patients with ventricular paced rhythms.The electrocardiographic diagnosis of ischemic heart disease is more difficult in the setting of ventricular-paced rhythms (VPR). ST segment/T wave configurations are changed by the altered intraventricular conduction associated with ventricular pacing. The anticipated, or expected, morphology in patients with VPR is one of QRS complex-ST segment/T wave discordance. An awareness of the anticipated ST segment morphologies of VPR is mandatory for the emergency physician. This knowledge is not dependent on additional diagnostic testing, medical records, or expertise in pacemaker function. Two cases are presented in which an analysis of the electrocardiogram in the setting of VPR assisted the treating physicians in establishing the correct diagnosis of acute myocardial infarction and arranging for urgent revascularization.- - - - - - - - - - ranking = 0.125keywords = heart disease, heart (Clic here for more details about this article) |
5/746. Transesophageal echocardiography and concurrent coronary angiography for the rapid assessment of papillary muscle rupture.echocardiography with color flow imaging is valuable for identifying mechanical complications of myocardial infarction. Transesophageal echocardiography is useful for critically ill patients in whom transthoracic imaging is often insufficient. A case of papillary muscle rupture is presented in which transesophageal echocardiography was performed concurrently with coronary angiography. The detailed information obtained from two-dimensional and color flow imaging eliminated the need for diagnostic right heart catheterization and left ventriculography. Transesophageal echocardiography used in this manner can facilitate expeditious surgical management.- - - - - - - - - - ranking = 0.053590249926418keywords = heart (Clic here for more details about this article) |
6/746. Treatment of acute myocardial infarction with prolonged intracoronary urokinase delivery through intracoronary infusion catheter.Severe acute myocardial infarction in young patients is plagued by high mortality. We report the case of a 25-year-old man, with a family history of ischemic heart disease, who was treated with acute and prolonged intracoronary urokinase infused through a miniaturized catheter engaged in a large thrombus occluding the left anterior descending artery. Rapid and stable recanalization was achieved with complete lysis of thrombotic material.- - - - - - - - - - ranking = 0.125keywords = heart disease, heart (Clic here for more details about this article) |
7/746. Acute myocardial infarction: a rare presentation of pancreatic carcinoma.Secondary neoplastic involvement of the heart is common but usually asymptomatic. Malignancy rarely presents as acute pericarditis, cardiac tamponade, and myocardial infarction in the same patient. We report a patient with unsuspected metastatic pancreatic adenocarcinoma who presented with acute pericarditis and cardiac tamponade and subsequently developed a myocardial infarction due to coronary artery occlusion secondary to a metastatic deposit around the left anterior descending artery.- - - - - - - - - - ranking = 0.053590249926418keywords = heart (Clic here for more details about this article) |
8/746. Left ventricular myxoma.A rare development of acute inferior myocardial infarction is reported in a 23-year-old man with no previous history of cardiovascular disease. In an echocardiographic study a left intraventricular tumour was diagnosed. Cineangiographic study showed normal coronary arteries. The tumour, a myxoma, originating in the ventricular septum, was resected through the left atrium after the anterior leaflet of the mitral valve was detached. Postoperative course was uneventful and the patient remained healthy 48 months after surgery.- - - - - - - - - - ranking = 0.0081248451897711keywords = valve (Clic here for more details about this article) |
9/746. Myocardial infarction caused by compression of anomalous circumflex coronary artery after mitral valve replacement.We report a case of myocardial infarction after mitral valve replacement occurring in a patient with the left cyrcumflex coronary artery arising from the right one. The patient underwent mitral valve replacement with a size 27 Carbomedics prosthesis and a tricuspidal annuloplasty was performed according to the De Vega technique. Patient died on the 20th postoperative day.- - - - - - - - - - ranking = 0.048749071138626keywords = valve (Clic here for more details about this article) |
10/746. Reversible catecholamine-induced cardiomyopathy in a heart transplant candidate without persistent or paroxysmal hypertension.BACKGROUND: Both dilated and hypertrophic cardiomyopathy have been reported in patients with pheochromocytoma, who were almost always hypertensive. The outcome frequently has been fatal, yet cardiac dysfunction can be reversible after medical or surgical therapy for the pheochromocytoma. methods: We report the case of a patient with dilated cardiomyopathy without persistent or paroxysmal hypertension, who was found to have a pheochromocytoma during initial medical evaluation. RESULTS: The identification and treatment of the pheochromocytoma led to significant improvement in cardiac function and cardiac transplantation was avoided. CONCLUSIONS: This case illustrates some unusual features in pheochromocytoma-induced cardiomyopathy: (1) absence of persistent or paroxysmal hypertension, (2) initial presentation with acute myocardial infarction and normal coronary arteries, and (3) recurrent episodes of nonsustained ventricular tachycardia.- - - - - - - - - - ranking = 0.21436099970567keywords = heart (Clic here for more details about this article) |
