A 1986 study found that coronary risk factors were receiving insufficient attention in patients who had recently undergone coronary artery bypass grafting. This issue was readdressed in a like group of 100 patients from the same surgical unit three and a half years later, in 1990, to ascertain whether risk factor management had improved over the period. An increased proportion of patients in 1990 were undergoing active management of hypertension and hyperlipidaemia. Only 25% of patients in 1990 manifested hypercholesterolaemia (cholesterol levels greater than or equal to 6.5 mmol/L) compared with 60% in 1986. Five per cent of patients in 1990 manifested diastolic hypertension (diastolic pressure greater than or equal to 95 mmHg) compared with 23% in 1986. Such patients appear better managed in 1990 than they were in 1986.

Coronary heart disease (CHD) is rare in Papua New Guinea (PNG) highlanders. Fifty-two men and 69 women randomly selected from three rural communities and a low socioeconomic urban community in the Eastern Highlands Province were assessed for hyperlipidemia, diabetes mellitus, diastolic hypertension and cigarette smoking. There was no significant difference between the findings in the rural and urban groups. The mean fasting levels of serum cholesterol, HDL cholesterol and apoproteins A-I and B were significantly lower (p less than 0.001) than those of rural Australians in a comparative study but the serum triglyceride levels were significantly higher in men less than 30 yr and women less than 40 yr of age. There was no significant difference in the serum cholesterol levels in men and women, and the levels of serum cholesterol and triglyceride did not rise with age. The mean fasting levels of plasma glucose were generally lower in PNG subjects and only two (1.7%) had diabetes mellitus. The proportions of highlanders who had diastolic hypertension or who smoked cigarettes were similar to those of Australian populations generally. The low incidence of CHD in PNG highlanders is probably related to the low serum cholesterol and apoprotein B levels, in turn probably related to their basically vegetarian diet and physically active life-style.

The participants in a community health survey in the Reykjavik area answered the question whether a first-degree relative had had myocardial infarction (MI), hypertension (HT) or cerebral stroke. The mean total serum cholesterol level was 5-10 mg/dl higher in the group with a positive history of MI than in the negative group. The frequency of hyperlipidaemia and the levels of other risk factors measured (blood pressure and body mass index) were similar in both groups. The group with a positive family history (FH) of HT had a mean systolic blood pressure 6-8 mmHg higher and diastolic hypertension (greater than 105 mmHg) on a single measurement twice as frequently as the negative group. The mean systolic blood pressure in the group with positive FH of stroke was 8-10 mmHg higher than in the negative group. The study thus suggests that positive FH of HT or stroke among first-degree relatives is a worthy indication for blood pressure measurements, at least after the age of 40.

This paper analyzed the mean of serum lipid and blood pressure, prevalence rates and risks of hyperlipemia and hypertension in 999 healthy rural women who had been taking Chinese No. 1 contraceptive pill for 5-25 years. Data was compared with those in 1 065 control subjects wearing IUDs in a series of cohort studies. The results showed that the level of serum triglycerides (TG), total cholesterol (TC), high density lipoprotein (HDL) and hypertriglyceridemia prevalence rate after long-term administration of contraceptive pill were significantly higher than that in control subjects (P < 0.01), which hypercholesterolemia prevalence rate did not increase significantly. The mean of systolic pressure and diastolic pressure in taking-pill group were 6.57 mmHg and 3.24 mmHg (lmmH = 0.133322kPa) respectively, higher than that of control group, but still maintained in the normal range. The prevalence rates of systolic hypertension and diastolic hypertension were higher than that of control group (P < 0.01). The results of multiple regression analysis suggested that long-term administration of Chinese No. 1 contraceptive pill had no marked influence on female hyperlipemia and hypertension after dispelling the effects caused by confounding factors.

Treatment of hypertension plays a key role in primary prevention of cerebrovascular attacks. Meta-analysis of 17 prospective studies of the treatment of hypertension proved that reduction of the systolic and diastolic blood pressure by 8-10/5-6 mmHg leads to a reduction of fatal and non-fatal cerebrovascular attacks by 40%. In the nineties a Swedish and British investigation of systolic-diastolic hypertension in elderly subjects-STOP and MRC-provided evidence of the great impact of treatment of hypertension in primary prevention of cerebrovascular attacks also in elderly hypertensive subjects (60-80 years). It is important to treat also in advanced age frequent isolated systolic hypertension as this improves markedly the prognosis of these patients and reduces the incidence of cerebrovascular and coronary complications, as was proved by the American study SHEP. The authors demonstrate that so far only the minority of hypertensive patients is treated effectively in this country and data from abroad indicate also that treatment of hypertension is lacking in the premorbid stage in more than half the patients with a cerebrovascular attack. The drugs of choice in treatment of hypertension in the elderly are small doses of thiazide diuretics and cardioselective beta-blockers or beta-blockers with ISA. By increasing the number of treated hypertensive patients, incl. elderly patients with a hypertension, and by increasing the effectiveness of treatment it is possible to achieve a decline of the cerebrovascular mortality; our objective must be a decline of the cerebrovascular mortality by more than 50%, similarly as it happened already in the USA. Conversely the importance of treatment of hypertension in secondary prevention of cerebrovascular attacks is controversial. The authors emphasize also the importance of abstinence from smoking as well as careful treatment of diabetes and hyperlipidaemia. Antiaggregation treatment has a greater impact in secondary prevention than treatment of hypertension. As regards the latter it should suffice to reduce the blood pressure to values of cca 150-160/90 -100 mmHg and not to normal values.

733 senior civil servants comprising 520 males and 213 females with a mean age of 44 years (range 25-56 years) were screened for their health status. The sample population comprised of 67.9% Malays, 22.5% Chinese, 9.1% Indians and 0.4% other ethnic origins. The subjects' medical histories were recorded and a full medical examination including anthropometric measurements (weight, height, waist and hip circumference), blood biochemistry and urine analysis, chest X-ray and electrocardiograms were done. The results obtained showed that 36.0% of the study population were overweight with 6.5% being obese. Of this 32.0% had central obesity. 15.2% of the subjects had systolic hypertension (systolic BP > or = 140 mmHg) whilst 27.6% had diastolic hypertension (diastolic BP > or = 90 mmHg). Hyperlipidaemia was common, with 75.2% subjects having raised cholesterol, 19.9% raised triglycerides, 50.2% raised LDL-C, 74.6% raised TC:HDL-C and 26.6% raised LDL:HDL-C. An elevated blood glucose was found in 8.4% subjects, whilst urine sugar was detected in only 2.6%, and a raised uric acid was found in 2.8% subjects. The prevalence of hypertension, raised blood glucose and hyperlipidaemia increased with age with more males affected than females. Although hypercholesterolaemia appeared more frequently amongst the Malays, the Indians, by comparison had the highest prevalence for a raised LDL:HDL-C ratio, a reflection of the increase in LDL-C and a concomitant decrease in HDL-C. The latter findings indicate that the Indians are at greater risk for the development of coronary heart disease than the Chinese and Malays. In addition, the mean levels of serum cholesterol found in this study seemed to have exceeded the levels found in populations in the industrialised countries such as the USA. There is thus an urgent need for more public health campaigns aimed at the reduction and control of such coronary risk factors.

Smoking, hypertension, and hyperlipidemia are the three most important modifiable risk factors contributing to the development of cardiovascular disease in older adults. Although the magnitude of risk associated with smoking and hyperlipidemia declines with age, the absolute number of cases attributable to these risk factors increases due to the increasing prevalence of cardiovascular disease. Smoking increases the risk of both coronary events and stroke in the elderly, and there is evidence that smoking cessation is associated with a rapid reduction in risk. Therefore, an aggressive effort to promote smoking cessation is strongly recommended in patients of all ages. Systolic and diastolic hypertension are powerful risk factors for cardiovascular disease in the elderly. Moreover, multiple clinical trials have demonstrated that blood pressure reduction reduces the risk of stroke, coronary events, heart failure, and cardiovascular death in individuals at least up to the age of 90. Accordingly, treatment of both systolic and diastolic hypertension are strongly recommended regardless of patient age. The importance of total serum cholesterol as a coronary risk factor declines with age, but the ratio of low density lipoprotein cholesterol (LDL-C) to high density lipoprotein cholesterol (HDL-C) remains an independent predictor of coronary events in older men and women. In addition, clinical trials have shown that cholesterol reduction is associated with improved clinical outcomes in individuals at or above 75 years of age. At the present time, the value of treating hyperlipidemia in patients greater than 80 years of age is unknown, and therapy in this age group must be individualized. (c)1999 by CVRR, Inc.

Oxidized low-density lipoprotein (LDL) exhibits various biological activities and accumulates in atheromas. LOX-1 (lectin-like oxidized LDL receptor) is the receptor that mediates oxidized LDL activity in vascular endothelial cells. Activation of LOX-1 results in oxidized LDL-induced endothelial dysfunction and hyperlipidemia-induced vascular lipid deposition. We hypothesized that LOX-1 is a candidate risk factor beyond LDL cholesterol (LDLC) and developed a novel assay to quantify LOX-1 ligand containing apoB (LAB). In men from the United States, serum LAB showed a significant positive association with carotid intima-media thickness, independent of LDLC. LAB and the LOX index (obtained by multiplying LAB by sLOX-1) were significantly associated with the incidence of coronary artery disease and ischemic stroke after adjusting for confounding factors, including non-HDL cholesterol. sLOX-1 is thought to be a better biomarker for early diagnosis of acute coronary syndrome than traditional biomarkers, including troponin T. LAB was associated with various atherosclerotic risk factors such as smoking, obesity, diabetes, diastolic hypertension, hypertriglyceridemia, and metabolic syndrome. Measurement of the soluble form of LOX-1 (sLOX-1) and LAB seems to be useful for evaluating the state and risk of atherosclerosis and atherosclerosis-related diseases. Further prospective studies using large populations and randomized clinical trials on sLOX-1, LAB, and the LOX index are needed.
