Isolated non inflammatory lesions of renal microarteries (eventually with mild thickening of tubular basement membranes, but with negative immunofluorescent glomerular studies) were observed in 25 patients (22 males) in whom renal biopsy have been performed for proteinuria (P). Selection criteria were: pathological lesions by definition; absence of hypertension (HT) in clinical and at the time of biopsy; minimum follow up of 4 years after the first statement of the proteinuria (4 to 29 years; mean 14 years). Three groups have been isolated: 1. 3 patients have had an acute glomerulonephritis followed by disappearance of proteinuria. It reappears 1 to 5 years later. HT was discovered 2, 8 and 11 years after the proteinuria. Renal failure occurred 1 and 3 years after HT. 2. 14 patients had hereditary or acquired vascular risk factors (obesity, smoking, ethylism). In 7, HT occurred 3 to 15 years after P. In 2, renal failure occurred 4 to 8 years later. 3. 8 patients had no vascular risk factor; in 3 of them Ht developed 7, 13 and 20 years after the first statement. A positive immunofluorescence with IgM or C3 on renal arterioles had been found in only 3 of the 10 patients who in group 2 and 3 became hypertensive. A proteinuria may precede the occurrence of HT without being induced by glomerulonephritis. Group 2 and 3 suggest that these renal lesions of arterial sclerosis precede and may be a factor of HT. Indeed, this entity may be considered as a prehypertensive condition.

The relation between hypertension and diabetic nephropathy is complex. Nephropathy is probably involved in the elevated blood pressure found in diabetic patients. In maturity onset diabetes, patients may also have hypertension which is associated with obesity or essential hypertension. It has been suggested that in both types of diabetes, hypertension enhances the development of diabetic nephropathy. Moreover, an aggressive antihypertensive treatment seems able to reduce rate of decline in kidney function in insulin-dependent diabetic patients with patent nephropathy. In this work, creatinine clearance and microalbuminuria in 20 diabetic patients (mostly with maturity-onset-diabetes) with known moderate and effectively treated hypertension were therefore measured and the results were compared with those for 18 normotensive diabetic patients and 22 controls. Duration of diabetes was from one to 26 years (mean: 11 years) and duration of hypertension was from one to 35 years (mean: 10 years). Patients and controls had normal serum creatinine and proteinuria below 0.1 g/l. Microalbuminuria was measured by immunonephelometric assay using specific antiserum (sensitivity = 1.5 mg/l; intra and interassay coefficients: 6.5% and 8% respectively). The highest value was observed in hypertensive diabetic patients with retinopathy (group 1). But hypertensive patients without retinopathy (group 2) and normotensive patients also had significantly increased microalbuminuria. In group 1, microalbuminuria was significantly higher than in group 2. The creatinine clearance was reduced in groups 1 and 2 versus normotensive diabetics, but hypertensive patients were older.(ABSTRACT TRUNCATED AT 250 WORDS)

Although cardiovascular mortality has decreased in recent years, it is still largely due to coronary disease: 1 out of 5 men and 1 out of 17 women are affected by that disease before the age of 60. Among the risk factors involved are lipid disturbances, themselves divided into three factors: LDL-cholesterol, triglycerides and HDL-cholesterol. A plasma LDL-cholesterol level above 150 units is a high risk factor. Triglyceride levels higher than 1.50 g/l, associated with HDL levels lower than 40 mg/dl constitute a new entity, a genetic disease associated with a special fragment on chromosome 11, characterized by high risk low HDL levels (below 40). Another risk factor, even in elderly people, is arterial hypertension. Cigarette smoking, lack of physical activity, diabetes and mental stress remain important factors, whereas obesity has become a separate factor. Finally, such factors as ECG abnormalities, plasma uric acide or plasminogen levels, familial context, etc., may be taken into consideration. All dietetic and therapeutic measures aimed at lowering the cholesterol level show a 2-3 p. 100 fall in the incidence of coronary disease for each 1 p. 100 reduction of blood cholesterol. A new programme, similar to those used in screening for high blood pressure subjects, will be set up in the U.S.A. to identify people with a blood cholesterol level higher than 2.40 g/l, treat them and bring that figure down below 2.00 g/l. The management of arterial hypertension is still based on treatments which do not increase blood cholesterol or increase HDL. They include alpha-blockers, beta-2 agonists and blockers of intracellular contractility. They have the additional advantage of improving capillary perfusion.

Pure systolic hypertension (PSH) is mainly observed in subjects over 60 years of age, and it is always due to a loss of compliance of the greater arteries. Blood pressure itself is partly responsible for loss of compliance, but other factors have been suggested. We have investigated this matter in a study of 3,388 subjects aged from 20 to 69 years. In a first stage, PSH patients (systolic BP greater than or equal to 160; diastolic BP less than 95 mmHg), aged from 50 to 59 years, were compared with normotensive subjects (systolic BP less than 140; diastolic BP less than 95 mmHg) and with other types of hypertensive patients with regard to cigarette smoking, alcohol consumption, obesity and plasma cholesterol, triglycerides, gamma-GT, glucose and uric acid levels. Several of these variables were significantly higher in all hypertensive patients than in normotensive subjects, but cigarette smoking and gamma-GT levels were predominantly or exclusively higher in PSH patients. In a second stage, correlations between differential BP and the variables listed above were studied in subjects with two levels of diastolic BP: 70-79 and 80-89 mmHg, thus taking into account all degrees between normal BP and PSH proper. Weakly positive correlations were found with alcohol consumption, plasma gamma-GT and glucose levels, and with percentages of smokers or ex-smokers. It is therefore conceivable that in addition to BP itself other factors, such as alcohol consumption, cigarette smoking and hyperglycaemia, contribute to the loss of arterial compliance progressively leading to pure systolic hypertension.

In order to study the relationships between hypertension, obesity and perinatal morbidity and mortality, we have studied a group of 264 women included in a cooperative prospective study with respect to obesity arbitrarily defined as a body mass index greater than or equal to 27 kg/m2. The obese and normal-weight groups comprised respectively 55 and 209 women of similar age (29.1 +/- 5.5 vs 30.2 +/- 5.3 years, NS). Obese women were less often primiparous than women with a normal weight (29.1 vs 50.2 p. 100, p less than 0.01). Hypertension before pregnancy was similarly frequent in both groups (41.8 vs 31.6 p. 100). Hypertension begun sooner during the pregnancy in the obese than in the normal group (17.1 +/- 11 vs 22 +/- 11 weeks of amenorrhea, p less than 0.01), the first abnormal blood pressure being comparable in both groups (156 +/- 15/96 +/- 14 vs 152 +/- 15/95 +/- 10 mmHg, NS). Indicators of perinatal risk were less often observed in the obese group: hypertension begins less often during the second trimester of the pregnancy (7.4 vs 21.7 p. 100, p less than 0.05), proteinuria greater than or equal to 2+ is more rare (13.0 vs 25.1 p. 100, p = 0.07), plasma urates are lower (maximum recorded value: 272 +/- 63 vs 322 +/- 96 mumol/l, p less than 0.001). No perinatal death occured in the obese group, as compared with 15 in the normal group (p less than 0.05). The weight of surviving babies was higher in the obese than in the normal group (3,294 +/- 596 vs 2,947 +/- 702 g, p less than 0.001), despite a comparable gestational age (38.3 +/- 2.3 vs 38.9 +/- 1.8 weeks, NS).(ABSTRACT TRUNCATED AT 250 WORDS)

The first objective is to correct any existing coronary risk factors but this must be achieved with discrimination. Smoking should be strictly forbidden, hypertension reduced and a more active life style encouraged. However, a more nuanced approach should be adopted towards dietetic problems, obesity and disorders of lipid metabolism. It is also very important to teach the patient to use glyceryl trinitrate correctly in the double objective of relieving pain as quickly as possible and of preventing pain by using it in certain critical situations. Clinical practice shows that patients often use glyceryl trinitrate too sparingly. When these general measures have been settled, treatment must be adapted to each particular situation. The patient's age, the frequency of attacks, trigger factors, the repercussions of the disease on the patient's life all have to be considered before deciding on the individual's treatment. In younger patients, a controlled exercise ECG is essential for selecting patients for surgery. The drugs of choice for stable angina are the betablockers which have been shown to be effective and well tolerated. When this group of drugs cannot be used or is ineffective, other major anti-anginal drugs may be chosen according to the individual terrain and their known secondary effects.

The results of a survey carried out in Marseilles between 1972 and 1979 are reported. A common protocol was used to compare results with two other surveys performed conjointly in Paris and Brussels. The protocol was designed with special emphasis on the psychological factors with respect to the risk factors for ischaemic heart disease (IHD). Seven hundred and eighty six men in a Marseilles administrative department, aged 40 to 60 years (mean age 48.5 +/- 4.5 years) were followed-up for 74 months. Apart from cardiovascular clinical examination with measurement of height, weight, blood pressure and ECG recording, the initial check-up included serum cholesterol, triglycerides and glucose determination and a study of psychological risk factors based on the Bortner's scale for the evaluation of type A profile, and on a questionnaire : the SHEPI for evaluation of the N score (neuroticism). The annual IHD incidence was 9.5% with 4.2% of major events (death or infarction), and 5.3% of minor events (angina pectoris, suggestive ECG changes). Age, tobacco consumption, average systolic blood pressure, serum cholesterol and obesity index were higher in patients who became ill than in those who remained healthy, but overall and separate analysis of major and minor events showed no significant difference apart from age. On the other hand, the study of increased risk according to the level of each of these major factors gave significantly positive results except for the serum glucose level. The correlations between incidence of IDH and the value of each risk factor were not always the same according to the clinical expression (major or minor events). Psychological factors also differed according to the clinical expression of IHD : the Bortner scale was higher in patients developing IHD than in healthy subjects, and higher in those who suffered major events than in those who suffered minor events. On the other hand, the N score was higher in patients with minor events than in those suffering major events. These differences which were not statistically significant in the Marseilles study alone, became significant in the Franco-Belgian cooperative study. The increased risk with the number of associated factors (including psychological) is significant from the association of 2 factors, but only in the fifth decade.(ABSTRACT TRUNCATED AT 400 WORDS)

Authors report two observations of embolus in the superior mesenteric artery. Patient's age, bad general status of the first, obesity of the second, importance of one emboli and especially affirmative angiography indicate treatment by streptokinase like the usual one in venous pathology. Good clinical result is approved by new control arteriography in two cases.

Two 44 year old female homozygote twins presented with cardiac ischaemia due to coronary atheroma, at 39 years of age and 43 years of age, respectively. The coronary risk factors (hypertension, cigarette smoking, hypercholesterolaemia, obesity, oral contraception) were comparable in both cases. Although presenting at different times, the electrocardiographic changes were in the same territory and coronary angiography showed a similar anatomical and lesional distribution. The literature is reviewed with respect to these cases to try to determine the respective roles of heredity and the environment in the initiation and progression of coronary atheroma.

An epidemiological and clinical study was carried out on 31 patients with spasm of normal coronary arteries. The series comprised 24 males and 7 females aged 30 to 68 years (mean age: 48 years) with isolated resting chest pain (61 p. 100) or with resting and effort chest pains (39 p. 100). Their cardiovascular risk factors were compared to 735 unselected patients with coronary insufficiency undergoing coronary coronary angiography. Abnormalities of lipid metabolism (45 p. 100) and obesity (14 p. 100) were less common but there was a higher incidence of smoking (74 p. 100 compared to 48 p. 100). Sixteen patients had a psychological test: repressed aggressivity and severe anxiety were found in all patients, a state of separation coincided wtih the onset of the illness in 10 of the 16 patients. On admission, 13 patients presented with attacks of Prinzmetal variant angina, with myocardial infarction in 2 cases. Eighteen patients had non-invalidating angina with sporadic attacks. Coronary angiography was normal in 8 patients and showed lesions with less than 50 p. 100 narrowing in the other 23 patients. Mitral valve prolapse was found on left ventriculography in four patients. Exercise electrocardiography was positive in 7 out of 20 patients, and notably in those who had not had effort angina. All patients were treated with calcium antagonist drugs (25 Nifedipine, 6 Diltiazem), the efficacity of which was tested in 20 patients with a control ergometrine test. Thirty patients were followed up for 6 to 46 months (mean: 15 months). The exercise stress tests were repeated in the 7 patients with positive results before treatment and the results were negative in all cases. Twenty three patients were completely pain free or significantly improved, although 25 p. 100 of control tests remained positive (4/16). Six patients continued to have as much chest pain, and three had positive control tests. One patient with a negative control test developed acute myocardial infarction six months later in the territory of the spasm: during hospitalisation the ergometrine test became positive again.
