In a group of 500 ambulant Pakistani patients suffering from diabetes mellitus, electrocardiographic evidence of coronary heart disease was present in 45 (9%). The frequency was higher in the males (12.1%) as compared to females (7.2%). The male diabetics with coronary heart disease had significantly high mean serum cholesterol values as compared to those without it. A positive family history of ischaemic heart disease, and the presence of small vessel disease as well as hypertension were more frequently associated with coronary heart disease. The overall frequency of hypertension was 21.2 per cent in this group of diabetics.

The occurrence of the C3F allele was investigated in the following three groups: 69 consecutive referred patients with untreated essential hypertension, including borderline hypertension; 70 patients with established and treated essential hypertension, already attending the same outpatient clinic, and 62 age- and sex-matched normotensive healthy subjects without clinical signs of atherosclerosis or familial predisposition to hypertension. In the three groups the C3F allele was found in 38.2%, 29% and 20%, respectively. Among the treated hypertensive patients with C3F gene, 40% had coronary heart disease (CHD) compared to 6.1% among the C3F negative (P less than 0.005), and the relative risk of CHD among the treated hypertensive patients with this allele was found to be 10.2 (P less than 0.002). The C3F gene was present in 72.7% of the treated patients with CHD. In the untreated patients the occurrence of CHD was low, and no differences between C3F positive and negative patients could be demonstrated. No association of the C3F allele with familial predisposition to hypertension was found. This study provides further evidence of a positive association of the C3F allele with atherosclerosis, and it is concluded that this allele in a hypertensive patient might accelerate the atherosclerotic process, with subsequent premature development of vascular complications.

Coronary heart disease (CHD) remains an uncommon disorder in the South African Black population. It has been suggested that herein lies an enigma, since it is believed that these people are considerably exposed to the conventional risk factors for CHD. To test this belief I have assessed the exposure of Black people, in time and degree, to the following CHD risk factors: affluence, age, hypertension, hyperlipidaemia, dietary excess, smoking, physical inactivity, diabetes, obesity, hyperuricaemia and hyperinsulinism. Among males only hypertension, and among females only hypertension and obesity, emerged as prominent factors. However, neither of these is significantly atherogenic in the social, nutritional and metabolic milieu in which Blacks generally live, and obesity is a doubtful atherogenic factor, even in westernized populations. It is therefore concluded that the rarity of CHD in Blacks is not enigmatic, but is appropriate to their environmental circumstances.

The relationship between sociocultural mobility and subsequent coronary heart disease (CHD) and hypertension (HT) was studied in a cohort of 13,728 male former Harvard University students examined in 1939-1950. All 13,728 were followed for CHD mortality, while 8852 returned self-administered mail questionnaires in 1962 or 1966 and in 1972 which queried for doctor-diagnosed myocardial infarction (MI), angina pectoris (AP) and HT. For each of 98 cases of fatal CHD, 78 cases of MI and 48 cases of AP, four controls were randomly selected. One control was selected for each of 319 HT cases. Significant negative associations between father's occupational status and risk of combined fatal CHD and MI and between geographic mobility and risk of HT were noted in univariate analysis. These associations persisted with stratification by individual confounding factors and by a multivariate confounder-summarizing score. Intergenerational mobility, as indicated by occupational status of the father, was associated with a 1.5 times increased risk of fatal CHD and MI. Intragenerational geographic mobility was associated with a slightly reduced risk of HT.

Obesity leads to several complications that affect many body systems. This paper focuses mainly on the cardiovascular complications, which include coronary heart disease, cerebrovascular disease and stroke, and congestive heart failure; the last may be secondary not only to advanced coronary atherosclerosis, but also to other pathogenetic factors. The increased frequency of coronary heart disease in the obese is largely attributable to the commonly associated hypertension, diabetes mellitus and lipoprotein abnormalities, rather than the adiposity. The lipoprotein disorders that have a role in atherogenesis are decreased plasma concentrations of high-density lipoproteins and elevated plasma concentrations of low-density lipoproteins. Abnormalities in cholesterol metabolism are responsible for the increased frequency of cholelithiasis in obese persons. The factors that mediate the development of cardiovascular and gallbladder complications are correctable by an appropriate program of meal planning and physical activity.

Gouty arthritis in females is relatively infrequent, although the sex ratio may be somewhat altered in different races. A positive family history is relatively prevalent among females whose onset of gout is premenopausal. In those patients with a postmenopausal onset, the incidence of diuretic-associated gout is high. The bimodal distribution of serum urate might be related to some variance of genetic transmission in female gout. Hypertension and coronary heart disease are common coexisting conditions, as is true of gouty arthritis in males. Chronic urinary tract infection dating from previous pregnancies is a frequent complication. The relative prevalence of proteinuria and diminished renal function leads to increased hyperuricemia, with a tendency to a low urinary uric acid output. This explains in part the higher incidence of extensive tophaceous deposition but lower incidence of renal calculi. Diuretics are associated with a higher urine pH, likewise, they reduce the urinary uric acid excretion. This also may contribute to the lower incidence of renal calculi. There may be some statistical support for the low fertility rate among the gouty females. Only two females became pregnant after the onset of gouty arthritis. All other pregnancies occurred before the onset of arthritis. Even then, abnormal pregnancies were relatively frequent. Some hormonal malfunction among the gouty females cannot be discounted. Both renal calculi and tophi are frequent in female gout associated with blood dyscrasias. They may manifest early, preceding the first attack of acute gouty arthritis. In both the male and female secondary gout, the primary underlying disease governs the uric acid metabolism and the clinical symptomatology of gout. The predominant role in pathogenesis is the excessive rate of uric acid production, and its disposal is governed by the different stages of the underlying disease and the treatment. Thus, secondary gout in females appears to be somewhat different from primary gout in females, but not different from secondary gout in males.

Major risk factors for coronary heart disease include hypertension, high serum cholesterol and triglyceride levels, and cigarette smoking. Minor risk factors include glucose intolerance, electrocardiographic changes, and personality type. Often the initial manifestation is angina pectoris. To prevent coronary heart disease, physicians need to know the answers to the following questions: (1) In which person will coronary heart disease develop, and when? (2) What is the cause? (3) What major and minor causative factors can be modified? (4) How can these modifications be achieved in a free-living, working, well population? (5) What is the earliest manifestation of coronary atherosclerosis? (6) What special diagnostic procedures are useful in coronary heart disease? These subjects are examined briefly.

In 50 patients with coronary heart disease (CHD) and 38 controls, comparative data on age, sex, serum cholesterol level, hypertension, obesity, diabetes, smoking habits, and ear-lobe creases were analyzed statistically. After adjustment for age differences, the factors which chiefly distinguished the two groups were the incidences of smoking, obesity, diabetes, and ear-lobe creases. Of these, the ear-lobe crease seemed to be correlated best with CHD, and may prove to be a useful diagnostic sign.

In epidemiology the concepts of relative and attributable risk are used to describe the statistical association between the incidence of a disease and the presence of possible risk factors. If the association is due to a cause-effect relationship, the attributable risk can be considered as an estimate for the reduction in incidence as a consequences of intervention. In order to get unbiased estimates these risks must be standardized for the influence of confounding variables. From data of the Framingham Study these risks, standardized for the confounding influence of age, are estimated for three risk factors related to the incidence of coronary heart disease (CHD)--hypertension, hypercholesterolemia and cigarette-smoking--both marginally and jointly. Under very optimistic assumptions a theoretical reduction in 12-year CHD incidence of a maximum of about 20% is estimated from the male Framingham sample by assumedly lowering systolic blood pressure and serum cholesterol. If only cigarette-smoking could be totally eliminated, the reduction is estimated at about 37%.

We have attempted to summarize the current controversies regarding risk factors and preventive measures for control of arteriosclerosis and coronary heart disease. Recognizing that the genesis and development of the disease process are extremely complex and the basic knowledge is limited, it is not likely that conclusive answers to questions will be forthcoming soon which will provide more effective preventive or therapeutic measures. It might be desirable to institute educational and control program aimed at curtailing, at a young age, known AS risk factors such as heavy smoking, particularly if the family history indicates severe risk. Few will question the normal approaches to the treatment of complications of coronary heart disease by control of hypertension, elevated cholesterol, and smoking. However, great caution must be exercised when trying to institute large scale modifications in prevailing life patterns, particularly when based on indefinite risk factor studies and in the face of potentially profound and frequently unknown consequences. The unknowns of atherosclerotic heart disease risk factors, coupled with uncertainties and even doubts about protracted and expensive population studies, lead us to propose an emphasis on alternate selective approaches. We strongly believe that fundamental to progress in the field of arteriosclerosis is an amplification of preventive research efforts with stronger attention focused upon influencing the atherosclerotic processes within the arterial wall. But, more immediately, we urge systematic gathering and careful evaluation of patient data in particular population subsets which exhibit and accelerated mode of arteriosclerosis. Comparative studies of patients, particularly twins, families, and ethnic populations with redilection to early or accelerated arteriosclerosis may be extremely rewarding. Our repeated review of the enormous literature suggests that worldwide collaboration is needed to perfect more meaningful protocols as well as to correlate and critically evaluate existing data provided by population studies of this insidious disease process which represents an evermounting burden to society.
