Epicardial Lymphoproliferative Disease Involving the Coronary Arteries

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 ...

Polyarteritis nodosa involving renal and coronary arteries.

External 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 ...

Epicardial 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...

Giant coronary artery aneurysms involving all three coronary arteries.

Coronary artery aneurysm is defined as any coronary artery dilation exceeding the diameter of normal adjacent segments or the diameter of the largest coronary artery by 1.5 times. Giant coronary aneurysm refers to an aneurysm with a diameter larger than 20 mm. Giant coronary artery aneurysms have an incidence of 0.02%-2%. Here we describe a patient who had giant coronary aneurysms involving all...
