Concentrations of various lipids and glycosaminoglycans (GAG) in the intima of the grossly normal and atherosclerotic cerebral arteries were compared with those of the aorta and coronary arteries. The lowest percentage of esterified cholesterol (EC) in total cholesterol, and of chondroitin sulfate-4/6 (CS-4/6) in total glycosaminoglycans and the highest percentage of heparin sulfate (HS) in tot...

In his review of the physiology of the coronary circulation, Wiggers (1936) enumerated three types of compensatory anastomosis that may develop after coronary occlusion: (1) through development ofnew ititercoronary communications, (2) through formation of extracardiac communications, and (3) through enlargement of arterio-luminal channels. Widespread minor anastomoses are known to exist between...

Granulomatosis with polyangiitis is a systemic disease resulting in necrotizing vasculitis of small- and medium-sized vessels. Cardiac involvement is rare and when present usually manifests with pericarditis and coronary artery vasculitis. We report here a case of granulomatosis with polyangiitis involving the native coronary arteries, bypass graft, and pericardium with interesting imaging find...

abstract background and purpose: epicardial fat is the true visceral fat located around the heart, particularly around sub-epicardial coronary arteries that may locally interact and modulate the coronary arteries and myocardium through paracrine or vasocrine secretion of anti-inflammatory and proatherogenic cytokines. most previous studies have used echocardiography and reported controversial r...

a 78-year-old woman was referred for coronary angiography with the chief complaint of exertional angina and dyspnea of a very long duration during routine daily physical activities. she had a history of poorly controlled hypertension and dyslipidemia. coronary angiography revealed diffuse three-vessel disease. interestingly, an unusual branch was noted originating from the mid shaft of the left...

Myocardial ischaemia may result from congenital abnormalities in the origin or distribution of the coronary arteries. Coronary obstruction may also develop at a young age in some rare hereditary disorders such as Hurler's syndrome, homocystinuria or pseudoxanthoma elasticum. The coronary arteries may be the site of embolism; ostial stenosis may complicate luetic (or other) aortitis or coronary ...

: Coronary artery fistula (CAF) is characterized by abnormal communication between the main coronary and cardiac chambers, pulmonary arteries, vena cava, systemic arteries veins, a rare malformation. Bronchiectasis involves remodeling persistent dilatation of bronchial airways. It can either be localized to one lung segment or diffused throughout whole lung. The incidence bronchiectasis has inc...

Fibromuscular dysplasia is a nonatherosclerotic and non-inflammatory vascular disease with primary lesion of renal and internal carotid arteries. We present a neonatal case of fibromuscular dysplasia who died on the second day of life. The newborn suffered from fibromuscular dysplasia of the coronary arteries and a congenital heart defect. The interesting feature of this case was the formation ...

BACKGROUND To study the arterial supply of the conducting system and its correlation with the dominance of the coronary arteries in the South Indian population. OBJECTIVE To determine angiographically the origins of the sinoatrial nodal artery (SAna) and atrioventricular nodal artery (AVna) in Indians. METHODS The study included 300 consecutive patients (114 females, 186 males; mean age, 55...
