Coronary arterial dissection is extremely rare. Such dissections have been reported to occur secondary to atherosclerosis, trauma, the postpartum state, and cystic medial necrosis and to be iatrogenically induced during catheterization. The clinical picture of coronary arterial dissection is usually sudded death. A review of the literature reveals that our case is the second in which a spontaneous coronary arterial dissection has been diagnosed during life and documented by coronary arteriographic studies. This report describes a 31-year-old man who presented with an acute inferior myocardial infarction. Coronary arteriographic studies demonstrated a dissection of the right coronary artery.

To investigate the significance of precordial ST-segment depression in acute inferior myocardial infarction, we compared the Gensini score of coronary artery stenosis between 2 groups of patients with and without precordial ST-segment depression. Group I consisted of 28 patients who showed ST-segment depression on admission (greater than or equal to 1 mm in V2-V6) and Group II (n = 16) those without ST-segment depression (less than 1 mm). The Gensini score of the coronary arteries (56 +/- 29 vs. 28 +/- 18; p less than 0.001), the partial score of the infarction-related artery (29 +/- 16 vs. 17 +/- 11; p less than 0.01) and of the infarction-nonrelated artery (27 +/- 24 vs. 11 +/- 12; p less than 0.02) were significantly higher in Group I than in Group II. The Killip score (greater than or equal to II) (34% vs. 6%; p less than 0.05), frequency of arrhythmias (75% vs. 38%; p less than 0.02) and peak CK value (3,676 +/- 2,290 vs. 1,818 +/- 1,153 IU/L; p less than 0.005) were higher in Group I than in Group II. Four patients in Group I died following admission, while no patient died in Group II (N.S.). Autopsy findings from the 4 Group I patients revealed fresh extensive inferior infarction and healed diffuse subendocardial infarction which could not be predicted from electrocardiograms. All patients who survived the acute stage performed treadmill exercise testing and 22 patients underwent exercise thallium-201 single photon emission computer tomography (SPECT). On treadmill exercise test, there was no significant difference between the 2 groups in the frequency of angina pectoris and ST-segment depression. On SPECT, the perfusion defect area under 55% of maximum uptake at the redistribution phase was 45.8 +/- 19.6 cm2 in Group I (n = 14) and 34.7 +/- 21.3 cm2 in Group II (n = 8; N.S.). In conclusion, precordial ST-segment depression in acute inferior myocardial infarction suggested advanced atherosclerosis in both the infarction-related and nonrelated coronary arteries, indicating a larger infarct size.

A 27-year-old man had inferior myocardial infarction following superficial chest trauma. Coronary arteriography documented an isolated total occlusion of the right coronary artery, probably caused by localized extra-coronary compression, and no other evidence of intrinsic coronary disease. The left anterior descending artery later developed a localized proximal stenosis, most likely due to mural thrombus, which progressed rapidly to cause anterior myocardial infarction despite coronary artery surgery. The etiology of this lesion is discussed and support given to the "encrustation" hypothesis of human atherosclerosis. Exercise thallium scintigraphy proved helpful in the management of this case.

Ultrasound is widely used for the diagnosis and follow-up of patients with many kinds of vasculitis. Transcutaneous or transesophageal two-dimensional ultrasound images can depict vascular wall lesions associated with vasculitis such as stenosis, aneurysm or wall thickening. Pulsed Doppler and color Doppler are useful for the assessment of stenoses and changes in blood flow. Recent progress in intravascular ultrasound apparatus made it possible to more precisely assess morphological changes in vascular wall. Intravascular ultrasound of a 27-year old male patient suffering from inferior myocardial infarction with right coronary aneurysms revealed calcification and fibrosis of the intima and early development of atherosclerosis in both right and left coronary arteries suggestive of the sequelae of Kawasaki disease.

The description of two additional cases of coronary artery disease in haemophiliacs is reported. Both patients are affected by mild haemophilia A. The first one was not aware of his coagulation disorder and therefore he had never been treated with FVIII concentrates, despite the occurrence of severe and recurrent articular and gastric bleeding episodes. He underwent cardiac catheterization that gave evidence of extensive coronary atherosclerosis. Percutaneous transluminal coronary angioplasty (PTCA) was then performed. The second patient had an inferior myocardial infarction. Influence of cardiovascular risk factors in haemophiliacs and the possible role of thrombosis in the pathogenesis of atherosclerosis are discussed.

A 47-year-old man with heterozygous familial hypercholesterolemia was followed up by coronary angiography for 9 years. During these 9 years, he experienced inferior myocardial infarction twice, at segment 1 of the right coronary artery. A coronary atherosclerotic lesion (50% stenosis) was also present at segment 6 of the left anterior descending coronary artery. This lesion remained unchanged for the first 7 years, but then rapidly progressed to 90% stenosis in the 8th year. While the rate of the progression of coronary atherosclerosis is generally unpredictable, it may progress rapidly in this case of heterozygous familial hypercholesterolemia.

We report the case of a patient with a past history of coronary atherosclerosis treated with primary angioplasty 5 hours following an inferior myocardial infarction. Echocardiography performed during the procedure revealed a mediastinal tumour invading the tricuspid, responsible for the occlusion of the right coronary. Infarction due to tumour compression is a rare presentation of mediastinal tumour. Diagnosis relies on echocardiographic, CT or magnetic resonance imaging. The prognosis is linked to the tumour pathology.

Long time ago lipids increased in blood have been known as risk factor for atherosclerosis that causes coronary heart disease among which myocardial infarction is the most complicated. Aim were to present the lipids status structure in patients with acute myocardial infarction and on the basis of that to suggest corresponding statin in treatment. Our research involved 202 patients with acute myocardial infarction, patients were both gender and from 37 to 89 year. Out of total number of patients, 100 of them were with anterior myocardial infarction (group I) and 102 with inferior myocardial infarction (group II). Whole cholesterol, low density lipoproteins, high density lipoproteins and triglycerides were followed. Hi square test and variance analysis were used to prove statistically significant difference. In the sample of group I increased LDL was found in 92 patients and increased TGL in 46 patients while decreased HDL was found in 61 patients. In the sample of group II increased LDL was found in 64 patients, increased TGL in 44 patients, while decreased HDL was found in 51 patients. We analysed the next combinations in both groups: LDL > with HDL <; LDL > with TGL >; HDL < with TGL >; LDL >, TGL > with HDL <. Combination decreased HDL with increased TGL was found in group I in 5 patients, and in group II in 12 patients. Other combinations in both groups were similarly values. On the basis of the obtained results we found statistically significant difference between the two groups of patients. Patients in group I have more frequently increased values of LDL in comparison to patients in group II (p < 0.00005). In patients in group II who had decreased HDL and increased TGL statistically significant difference was found in comparison to the patients in group I (p < 0.02). On the basis of the obtained results and up to now studies on statins effects we suggest Atorvastatin for treatment the patients with anterior myocardial infarction, increased LDL with normal values of HDL and Simvastatin for treatment the patients with inferior myocardial infarction, decreased HDL.

Acute myocardial infarction complicated by cardiogenic shock in a patient with Leriche syndrome - a case report. A 46-year-old male with atherosclerosis obliterans was admitted to the hospital due to chest pain lasting for two hours and signs of cardiogenic shock. ECG revealed postero-inferior myocardial infarction. The patient was successfully treated with primary angioplasty of RCA. Due to atherosclerosis obliterans angioplasty was performed by transulnar approach. After 22 days of treatment and rehabilitation he was discharged home.

A 70-year-old man experienced an amoxycillin-induced anaphylactic reaction complicated by acute inferior myocardial infarction with transient ST-segment elevation. There was a spontaneous resolution of ST-segment elevation and the patient was treated for anaphylaxis. Coronary angiography showed severe obstructive coronary atherosclerosis, but not involving the infarct-related artery. Percutaneous coronary intervention of the affected artery was then performed and the patient was discharged three days later. Acute ST-elevation myocardial infarction has been described as one of the severe, still rare cardiovascular complications of anaphylaxis. In the present case, according to the previous reports, the main pathogenetic mechanism involved appears to have been coronary vasospasm probably caused by the release of potent vasoactive mast cell derived mediators in the setting of anaphylaxis.
