Up to date only 13 cases of left main coronary artery aneurysms have been reported in literature; of these, 8 were associated with atherosclerosis. This report details the case of a large aneurysm of left main coronary artery angiographically documented in 46-year old man with exertional angina pectoris and myocardial infarction.

While studying the functional activity of poly- and mononuclear leucocytes in 75 patients with various clinical types of ischemic heart disease (angina of effort, angina decubitus, arrhythmias, cardiac insufficiency at the background of atherosclerotic cardiosclerosis and atherosclerotic hypertension), decline in the functional activity of the phagocytizing cells has been revealed, this being considered to be a pathogenetic prerequisite for atherosclerosis progression.

Population kinetics of monocytes (MC) was studied to prove their participation in atherogenesis. Increased number of cells containing lipids (CCL) in patients with severe stable angina pectoris is demonstrated (42.5 versus 7.4% in healthy persons). This is followed by MC esterase activity enhancement. In patients with angina of effort new types of MC appear (with high peroxidase and low esterase activity) and there is a drastic increase of CCL (more than 56%). The correlation between the number of CCL and indices of blood lipid metabolism in anginal patients is lacking. The results obtained may serve as a criterion for evaluating the degree and exacerbation of coronary atherosclerosis in humans.

A 54-year-old man suffering from effort angina pectoris had an anomalous origin of the left anterior descending coronary artery (LAD) from the right sinus of Valsalva (RSV). The anomalous LAD with a small ostium and without other significant narrowing initially ran into the interventricular septum and subsequently the anterior interventricular groove. Coronary angiography during the anginal attack induced by ergometer exercise testing revealed neither an enhanced narrowing of the LAD ostium, nor myocardial squeezing of the LAD at the interventricular septum level, nor coronary vasospasm. Myocardial ischaemia associated with an anomalous aortic origin of the LAD from the RSV is extremely rare, especially when the vessel runs a septal course. In the present case, the ostial stenosis of the anomalous LAD, probably due to developed atherosclerosis, seemed to be the most likely cause of the exertional angina.

Homozygous familial hypercholesterolaemia is a rare inherited condition with an incidence of approximately one in a million. It is associated with severe premature atherosclerosis and early death from cardiovascular complications. The results of liver transplantation reported to date have suggested only partially effective reduction of the hypercholesterolaemia. Three boys with familial hypercholesterolaemia, aged 10.0 to 15.1 years, received liver grafts at Addenbrooke's Hospital. Their untreated fasting lipid concentrations were grossly raised. All three had angiographic evidence of coronary atheroma and two had exertional angina. One child had such severe atheroma that coronary artery bypass surgery was considered necessary before liver transplantation. All three had straightforward operative and postoperative courses and their lipid concentrations returned rapidly to normal. One boy developed chronic rejection requiring retransplantation. Currently all three boys are well, on normal diets, and with normal liver function. It is concluded that (1) liver transplantation offers highly effective treatment for this lethal condition, (2) timing the operation is difficult but it should be undertaken before coronary artery disease has progressed too far (when combined liver and heart transplantation may be the only possibility), and (3) in well grown children with no previous abdominal surgery the immediate risks of liver transplantation are low but chronic rejection remains a danger.

Coronary artery aneurysm is a rare coronary abnormality, usually diagnosed incidentally by coronary angiography. Major causes of coronary aneurysms include coronary ectasia, Kawasaki disease, and atherosclerosis. Most of the discrete coronary aneurysms are of atherosclerotic origin. The incidence of atherosclerotic coronary aneurysms is about 0.2%, and the left main coronary artery is the least frequently involved artery. Only a few cases of left main coronary artery aneurysm have been reported in the literature, and a left main coronary artery aneurysm involving the proximal segments of the left anterior descending and the left circumflex arteries has not been reported previously. The authors describe this finding in a man who presented with worsening exertional angina pectoris. Coronary angiography demonstrated an aneurysm of the distal left main coronary artery extending into the proximal segments of the left anterior descending and the left circumflex arteries. In addition, a significant flow-limiting atherosclerotic lesion was present in the proximal portion of the left anterior descending artery distal to the aneurysm.

We present the case of a 59-year-old man, with exertional angina, atrial fibrillation, electrocardiographic and scintigraphic signs of inferior necrosis and anterior ischemia. An abnormally high take off of the right coronary artery, with anomalous intraaortic initial pathway, was objectified in the patient by means of angiography and magnetic resonance imaging. The patient did not have coronary atherosclerosis or intracoronary lesions.

We report the case of a 65-year-old man affected by idiopathic thrombocytopenic purpura, who developed an acute myocardial infarction after 2 years of steroid therapy. Thrombocytopenia was initially recognized 11 years earlier, and became severe during the past 2 years [platelets (PLTS) 10000-30000/microl]. He was treated with steroids, initially to perform a surgical procedure (prednisone 75 mg/day), subsequently to maintain a platelet count of about 50000/microl (prednisone 12.5 mg/day). After 1 year of treatment, he began to complain about exertional angina and dyspnea. His blood pressure became elevated and cholesterol level raised. The exercise electrocardiogram, previously manifesting ischaemic changes, normalized after 1 month of steroid wash-out; however, steroid therapy was reinstituted (prednisone 5 mg per day). One year later, he suffered an infero-lateral non-Q-wave myocardial infarction. It seems likely that the severe coronary atherosclerosis present in our patient developed despite a low platelet count, under the spur of a heavier risk factor profile. Steroid therapy could have had a role as a precipitating agent of the acute event, and the opportunity of alternative treatments is considered.

Monocyte chemoattractant protein-1 (MCP-1) plays an important role in the progression of atherosclerosis in coronary arteries. To examine whether or not plasma antigen levels of MCP-1 are related to restenosis after percutaneous transluminal coronary angioplasty (PTCA), the plasma antigen levels of MCP-1 were measured by enzyme-linked immunosorbent assay (pg/ml) before, 24 and 48 h, and 3 months after elective PTCA for stable exertional angina performed between June 1997 and March 1998. Restenosis was defined as recurrence of stenosis greater than 50% of the diameter in the dilated segment at 3-month follow-up angiography. There were no differences in plasma MCP-1 antigen levels before and at 24 h after PTCA between restenosis (R; n=27) and no-restenosis (N; n=43) groups (R vs N: 633+/-35 vs 589+/-34, and 669+/-41 vs 575+/-36 pg/ml before and at 24 h after PTCA, respectively), but plasma MCP-1 antigen levels were higher at 48 h and 3 months after PTCA in the R than in N group (R vs N: 678+/-41 vs 558+/-35, and 735+/-35 vs 571+/-32 pg/ml at 48 h and 3 months after PTCA, respectively). These data suggest that the MCP-1 production and macrophage accumulation in the balloon-injured site is partially associated with restenosis after PTCA.

Oxidized low-density lipoproteins are important in the progression of atherosclerosis. Autoantibodies against malondialdehyde-modified low-density lipoproteins have been reported to be predictive of the progression of atherosclerosis. This study sought to examine whether plasma levels of autoantibodies against oxidized low-density lipoprotein increase in the coronary circulation in patients with coronary spastic angina. The authors examined plasma antioxidized low-density lipoprotein antibody levels (activity unit values (AcU)/mL) simultaneously in the coronary sinus and the aortic root in 20 patients with coronary spastic angina, 23 patients with stable exertional angina, and 15 control subjects by measuring plasma levels of immunoglobulin G (IgG) autoantibodies against malondialdehyde-modified low-density lipoproteins by enzyme-linked immunosorbent assay. The plasma antioxidized low-density lipoprotein antibody levels (AcU/mL) in the coronary sinus increased in coronary spastic angina (38 +/- 16) compared with stable exertional angina (23 +/- 7) and control subjects (20 +/- 6) (p < or = 0.0001). The levels (AcU/mL) in the aortic root also increased in coronary spastic angina (33 +/- 12) compared with stable exertional angina (23 +/- 7) and control subjects (20 +/- 6) (p < 0.005). Furthermore, the coronary sinus-arterial differences of the levels (AcU/mL) were also higher in coronary spastic angina (5 +/- 9) than in stable exertional angina (0 +/- 6) and healthy subjects (-1 +/- 5) (p < 0.05). The generation of malondialdehyde-modified low-density lipoproteins is reported to be associated with atherothrombosis. These findings suggest that elevated levels of autoantibodies against malondialdehyde-modified oxidized low-density lipoproteins in coronary circulation are associated with the development of atherothrombosis from the progression of atherosclerosis rather than with the extent of coronary atherosclerosis in patients with coronary spastic angina.
