Peptidergic innervation of human epicardial coronary arteries.
The peptidergic innervation of proximal (internal diameter, > 0.8 mm) and distal (internal diameter, < 0.8 mm) regions of human epicardial coronary arteries was investigated by means of immunohistochemical, chromatographic, radioimmunological, and in vitro pharmacological techniques. The use of an antiserum to the general neuronal marker protein gene product 9.5 revealed that the proximal part ...
متن کاملExternal Compression of Epicardial Coronary Arteries with Partial Calcific Pericarditis
Calcific pericarditis (CP) is a rare disease which results from long-standing pericardial inflammation. Pericardial calcification may completely or partially encase the ventricles, resulting in impaired diastolic filling. We present a case of a 53-year-old male who was incidentally found to have annular CP resulting in external compression of a large territory diagonal branch (D1) reaching the ...
متن کاملEpicardial Coronary Arteries in Khat Chewers Presenting with Myocardial Infarction
Background. Khat chewing is a common habit in Yemen despite increased evidence of its negative impact on the cardiovascular system. Aims. We aimed to study the epicardial coronary arteries in khat chewers presenting with myocardial infarction (AMI). Materials and Methods. A descriptive, cross-sectional study was conducted between November 2008 and May 2009 in Yemen. AMI patients who underwent c...
متن کاملReactivity of Canine Isolated Epicardial Collateral Coronary Arteries
To study the relation between structure and vascular reactivity in mature coronary collateral arteries, we prepared 17 dogs with a casein occluder near the origin of the circumflex coronary artery. At least 24 weeks later, we examined the reactivity of surface collateral arteries (-500 ,um i.d.) to a range of constrictor and dilator agents and compared them with normal left anterior descending ...
متن کاملAcute and chronic effects of epicardial radiofrequency applications delivered on epicardial coronary arteries.
BACKGROUND Epicardial coronary injury is by far the most feared complication of epicardial ablation. Little information is available regarding the chronic effects of delivering radiofrequency in the vicinity of large coronary vessels, and the long-term impact of this approach for mapping and ablation on epicardial vessel integrity is poorly understood. Therefore, the aim of this study was to ch...
