Background. The mechanism of stroke in beta-thalassemia was reported previously as cardioembolic and hypercoagulable state. However, there is no report of watershed infarct in beta-thalassemia anemia. Method. We present an adult β-thalassemia major patient with manifest asymptomatic chronic left carotid occlusion who suffered watershed infarct. Result. In the presence of asymptomatic chronic le...

Although several diagnostic modalities are available to the clinician interested in diagnosing coronary artery disease, very few have been validated in diabetic populations. This review discusses the non-invasive diagnosis of coronary disease in diabetic patients. Evidence regarding the prevalence and prognostic significance of silent ischemia is reviewed and the potential impact of silent isch...

The absent or atypical clinical signs in elderly persons hinder the management of coronary atherosclerotic disease. The cases of myocardial ischemia without pain, the so-called asymptomatic or silent ischemia, it is more frequent in elderly patient2. Considering patients with acute coronary syndrome, as myocardial infarction with ST-segment elevation, among those under 65 years of age, only 11....

A coronary-bronchial artery fistula is a very rare congenital anomaly of the coronary artery whose etiology and pathogenesis have not yet been clarified. Most patients with coronary-bronchial fistulas are asymptomatic; however, some patients present with congestive heart failure, infective endocarditis, myocardial ischemia induced by a coronary steal phenomenon, or rupture of an aneurysmal fist...

Idiopathic hypereosinophilic syndrome (HES) is characterized by persistent eosinophilia and eosinophil-mediated organ-system damage. Cardiac thrombosis and thromboembolic complications represent common causes of morbidity and mortality and usually involve cardiac ventricles or mitral and prosthetic valves, while the involvement of the aortic valve is extremely rare in HES. Here we report peculi...

A retrospective analysis of 54 patients with atrial fibrillation presenting with symptoms of cerebral ischemia between 1980 and 1985 was performed. Seven patients (13%) had computed tomographic evidence of previous, clinically silent cerebral infarction. In a control group of 168 persons (studied prospectively) in sinus rhythm presenting with symptoms of cerebral ischemia, seven (4%) had comput...

chest pain group. 3) Effective treatment: The efficacy of three standard antianginal drugs on silent myocardial ischemia was studied in 43 patients with EA using Holter monitoring. Antianginal drugs used were long-acting isosorbide dinitrate 40-80 mg/day for nitrates (17 patients), diltiazem 90-180 mg/day for calcium antagonists (13 patients), propranolol 30-60 mg/day or metoprolol 60-120 mg/da...

Coronary artery fistula is a rare congenital anomaly. Most patients with this anomaly are asymptomatic, but some may develop heart failure, myocardial ischemia or arrhythmias. We report a case of a patient who presented with myocardial ischemia secondary to persistent Thebesian veins. Coronary angiography demonstrated a marked capillary blush draining into the left ventricular cavity through mu...

A 43-year-old man with angina for 15 years underwent coronary angiography, which showed an anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva with a 30-40% fibrous stenosis in the proximal part of the artery, which was presumably responsible for the patient's symptoms. Myocardial scintigraphy (Tc-99 m Cardiolite) suggested reversible ischemia at the apex and the...

This paper addresses the question of whether and how MCG tests that assess ischemia or viability of the myocardium can add to the diagnostic information gained from standard procedures in asymptomatic and symptomatic patients. We review the diagnostic performance of the exercise electrocardiogram (ECG), the exercise and pharmacological (stress) echocardiogram, the exercise and pharmacological m...
