The mortality rate from heart disease is much higher among the Japanese of Hawaii than those of Japan. A comparison of autopsy specimens from men who died in Honolulu and Hiroshima indicated that this difference can be explained by more frequent myocardial infarcts in the Hawaii population. The basis for this difference can, in turn, be explained by the presence of more severe degrees of coronary atherosclerosis among the Hawaii men. The mortality rates for stroke, on the other hand, are higher among the indigenous Japanese than among Hawaii Japanese men. The basis for this difference cannot be explained on the basis of atherosclerosis of the aorta or of the circle of Willis. This report summarizes the comparative anatomic studies of coronary arteries, aorta and circle of Willis that form the basis for these conclusions.

Since the introduction of cyclosporine in the early 1980s, there has been a surge of activity in the field of pediatric heart transplantation. Careful patient selection has resulted in operative and short-term patient survival comparable to that achieved in adult transplant programs. The results of neonatal heart transplantation have been exciting and encouraging; neonates may require less immunosuppressive therapy than older infants and children. Transplantation clearly offers the chance of survival and significant rehabilitation to children with end-stage heart disease. Long-term management issues include the effects of chronic immunosuppressive therapy on growth and development and renal function, and the time-related risk of rejection, infectious complications, neoplasms, and graft atherosclerosis.

A 34 year old female had a history of dizziness and presyncope. She had many risk factors for atherosclerosis including smoking 30 packs of cigarettes/year, using oral contraceptives (OCs) for almost 10 years, somewhat elevated blood sugars, strong family history of heart disease and diabetes, and hypertension. During an examination in 1983, she had an elevated blood pressure in the right arm but a reading could not be found in the left arm. The physician heard a grade III rough, blowing systolic bruit over the right subclavian artery moving into the right carotid artery. Pulses of both carotid arteries were normal. Heart sounds were normal. While the right brachial and radial pulses were fine, there were none on the left side. Laboratory tests showed a serum cholesterol of 258 mg/dl, a fasting blood sugar of 92 mg/dl, a white blood cell count of 8400, and a normal differential count. The arch aortogram showed a 50-60% stenosis beginning at the innominate artery and a completely occluded left subclavian artery at its origin. Physicians performed an aortoinnominate bypass operation using a Dacron prosthetic graft. This operation alleviated the symptoms, but 2 years later she had bilateral dysesthesias in her upper arms and vertigo returned. Her right arm became more and more limp while her left arm did so mildly. The aortoinnominate graft and the left subclavian artery were occluded. Physicians did coronary angioplasty using the right transfemoral route and corrected both lesions in her brachiocephalic system. they used a technique which eased safe crossing of the occluded subclavian segment (covering the catheter tip with a J curve guidewire). Following the operation, the patient had superb brachial and radial pulses in both arms. Physicians advised her to discontinue using OCs and tobacco products. At months 1 and 5, the symptoms were gone and vital signs were fine.

Atherosclerosis and its consequences are a significant cause of death in industrialized countries. In recent years, due to modern techniques which permit DNA analysis, a series of alleles associated with dyslipoproteinemia and heart disease have been identified. In this study these genetic markers, in particular those found at the level of the genes of apolipoproteins, are reviewed. The knowledge of these facts is important for the paediatrician, since these disturbances can be identified in the first days of an individual's life, thus a positive influence can be made over the lifestyle habits.

The authors describe the clinical-pathologic findings in four patients with myocardial infarct (MI) associated with Chagas' disease, found among 181 autopsies of chronic congestive cardiac chagasic patients. Organized thrombo-embolus was found in the epicardial portion of a coronary artery in one instance and thrombosis in the apex of the left ventricle as well as systemic infarcts were found in all cases. These data suggest thrombo-embolism, probably from the apex of the left ventricle, as a possible cause for the regional (large; transmural) MI in chronic Chagas' heart disease. The mechanism usually operative in MI, i.e. complicated atherosclerosis, was not present in the patients of this series. Moreover, our data do not support either small artery disease or heart denervation as etiologic factors for regional MI.

Vascular problems involving the brachiocephalic vessels may occur from atherosclerosis, trauma, vasculitis, infection, and procedures for congenital heart disease. A wide variety of symptoms and signs may result from such disorders. This study is a report of five unusual manifestations of brachiocephalic vascular diseases. Diagnosis, management, and previous surgical experience is discussed relating to each case illustrating the complexity and variability of brachiocephalic vascular pathology.

Heart transplantation in children is being performed with increasing frequency. As experience has accrued, problems of rejection, graft atherosclerosis, and growth have been noted. Seventeen children (seven boys and 10 girls) between the ages of 5 months and 14 years have undergone heart transplantation since 1981. The preoperative diagnosis was cardiomyopathy in 13 children, congenital heart disease in two, and endocardial fibroelastosis in two. Immunosuppressive therapy has included a tapering schedule of cyclosporine, azathioprine, and prednisone. There are 13 children alive, with four hospital deaths (two of infection, one of rejection, and one of graft failure). Rejection occurs as frequently in children as in adults. Two children have undergone retransplantation for rejection. Long-term hemodynamics are normal. Growth has been delayed in two of five children who are younger than age 10 years. Kidney function remains stable. Rehabilitation is 100% among the discharged patients. Heart transplantation in children represents an effective therapeutic modality. Heart transplantation in the young has emphasized morbidity caused by current immunosuppressive agents.

We assessed the severity of carotid atherosclerosis in 412 men from eastern Finland aged 42, 48, 54 or 60 years at examination with B-mode ultrasonography in 1987 in the Kuopi ischaemic Heart Disease Risk Factor Study (KIHD). Thirty-seven per cent of participants had intimal-medial thickening, 10% had plaques and 2% had stenosis. Age (P less than 0.001), cigarette-years (P less than 0.001), serum LDL cholesterol (P = 0.005), low income (P = 0.020) and low alcohol consumption (P = 0.048) had significant partial associations with the severity of carotid atherosclerosis. A linear regression model including these variables and plasma fibrinogen (NS) and serum HDL-cholesterol (NS) accounted for 33% of the variation in atherosclerosis severity. Our data provide further evidence on the role of smoking and LDL-cholesterol in atherosclerosis.

As diabetologists in the United Kingdom we care for our patients against a background of one the highest population rates of coronary heart disease (CHD) in the world. As emerging evidence serves to confirm the pivotal role of blood cholesterol and particularly low density lipoprotein (LDL) cholesterol in the development of atherosclerosis-related disease, it is timely to consider the importance of lipid and lipoprotein disorders in diabetes. Although specific microvascular disease contributes significantly, atherosclerosis remains the most important cause of morbidity and mortality in long-standing diabetes. From epidemiological studies of different populations, particularly the Japanese, it is clear that premature CHD is not an inevitable consequence of diabetes. This provides encouragement for prevention especially given the recent impetus in the understanding of the role of blood lipids in the pathogenesis of atherosclerosis. In this short review I will highlight some recent developments in the cholesterol/heart disease story, how the diabetic state may influence lipid and lipoprotein metabolism and how hyperlipoproteinaemia in the diabetic should be managed.

Although the majority of American women believe that oral contraceptives can cause serious health problems such as cancer or heart disease, the scientific literature does not support these beliefs. Oral contraceptives actually protect against endometrial and ovarian cancer. The increased incidence of cardiovascular disease in oral contraceptive users, including myocardial infarction, appears to be caused by thrombosis and not atherosclerosis. The studies suggesting an increased risk of cardiovascular disease in oral contraceptive users were published in the late 1970s and therefore used a data base of women ingesting formulations containing 50 micrograms of estrogen or more. More recently published data involving healthy women taking mainly lower estrogen dose preparations suggest that there is no increased incidence of myocardial infarction or stroke. Nearly all published studies indicate that there is no increased risk of myocardial infarction in former users of oral contraceptives. Animal data actually suggest that oral contraceptives may have a protective effect against atherosclerosis, even in the presence of lowered high-density lipoprotein levels. The low-dose triphasic and monophasic formulations are effective, safe methods of contraception that can be used by most healthy women of reproductive age.
