Low Dose Aspirin

SummaryAspirin and statins are beneficial in coronary heart disease across a broad range of cholesterol levels. We assessed the effects of low-dose aspirin (75 mg daily) on thrombin generation in patients with coronary heart disease and average blood cholesterol levels. We also investigated whether in patients with borderline-high cholesterol level who have been already taking aspirin, additional treatment with simvastatin would affect thrombin generation.Seven-day treatment with low-dose aspirin decreased thrombin generation ex vivo only in patients with total cholesterol 5.2 mmol/L. In patients with higher cholesterol levels aspirin had no effect. In these patients, already taking low-dose aspirin, additional three-month simvastatin treatment resulted in a reduction of thrombin generation. This demonstrates that low-dose aspirin depresses thrombin generation only in subjects with desirable blood cholesterol levels, while in others, with borderline-high cholesterol, thrombin formation is being reduced following the addition of simvastatin.

Atherosclerosis Prevention

PEDIATRIC GENESIS OF ATHEROSCLEROSIS Atherosclerosis results from a variety of pathophysiologic disturbances, some currently recognized, and many undoubtedly not yet recognized, which in aggregate are identified as risk factors. Genetic and environmental influences conjointly affect the incidence and the severity of these risk factors and, thus, coronary heart disease (CHD) risk. Prophylaxis should be designed to prevent or retard the development of arterial plaques. This suggests that diagnostic and preventive efforts should begin in childhood. Eating habits are also probably established in childhood, allowing their early modification. The atherosclerotic plaque appears to have its genesis in childhood. The data from wartime autopsies confirm the presence of mature atherosclerotic lesions by the end of the second decade and emphasize the importance of primary atherosclerosis prevention beginning in the first and second decades. While there are clearly genetic factors in CHD, variation in rates in differing geographic areas appears less likely to be related to genetic than to environmental differences. Marked differences in plasma cholesterol levels are found in children in different geographic areas, generally paralleling pediatric cholesterol and saturated fat intake and the incidence of adult coronary heart disease. The relationships of elevated total plasma cholesterol levels to the incidence of coronary heart disease are clearly established in adults.

Background Dietary habits are associated with obesity which is a risk factor for coronary heart disease. The objective is to estimate the change of lipoprotein(a) and other lipoprotein classes by calorie restriction with obesity index and Framingham risk score. Methods Sixty females (56 ± 9 years) were recruited. Their caloric intakes were reduced during the six-month period, and the calorie from fat was not more than 30%. Lipoprotein profiles were estimated at baseline and after the six-month period of calorie restriction. Cholesterol levels in six lipoprotein classes (HDL, LDL, IDL, VLDL, chylomicron and lipoprotein(a)) were analysed by anion-exchange liquid chromatography. The other tests were analysed by general methods. Additionally, Framingham risk score for predicting 10-year coronary heart disease risk was calculated. Results Body mass index, waist circumference, insulin resistance, Framingham risk score, total cholesterol, LDL-cholesterol and IDL-cholesterol were significantly decreased by the calorie restriction, and the protein and cholesterol levels of lipoprotein(a) were significantly increased. The change of body mass index was significantly correlated with those of TC, VLDL-cholesterol and chylomicron-cholesterol, and that of waist circumference was significantly correlated with that of chylomicron-cholesterol. The change of Framingham risk score was significantly correlated with the change of IDL-C. Conclusion Obesity indexes and Framingham risk score were reduced by the dietary modification. Lipoprotein profile was improved with the reduction of obesity indexes, but lipoprotein(a) was increased. The changes of obesity indexes and Framingham risk score were related with those of triglyceride-rich lipoproteins, e.g. IDL, VLDL and CM.

Hypothyroid Patients

SUMMARY 1. Certain analogues of thyroxine have been administered to twenty-six hypothyroid patients and 132 euthyroid hypercholesterolaemic men with coronary heart disease. The analogues studied were d-thyroxine, 3:5:3′:5′-tetraiodothyroformic acid, 3:5:3′:5′-tetraiodothyronamine, 3:5:3′-triiodo-l-thyronine, 3:5:3′-triiodo-d-thyronine, 3:5:3′-triiodothyroacetic acid, 3:5-diiodo-l-thyronine, 3:5-diiodo-d-thyronine and 3:5-diiodothyroacetic acid. 2. In both hypothyroid and euthyroid patients, most of these analogues reduced the serum cholesterol without necessarily elevating the basal metabolic rate (b.m.r.). Nevertheless, in euthyroid patients with coronary heart disease several produced angina in the absence of any change in b.m.r. and this has been regarded as a sign of increased myocardial metabolism insufficient to be reflected in the overall measure of b.m.r. of all tissues. The possible differential effect of these analogues on the oxygen requirements of various tissues is discussed. 3. Although it has been possible to maintain low cholesterol levels for periods up to 3 months during the administration of several of these analogues, the dose required for this purpose was often so close to the dose which provoked angina that most cannot be recommended for widespread administration for the reduction of the hypercholesterolaemia frequently found in patients who have coronary heart disease. d-Thyroxine may prove to be an exception and requires further clinical assessment.
