The diagnosis of lactate acidosis is complicated by the fact that lactate determination is not a routine method in clinical chemistry. In fact, lactate analysis is performed only in special laboratories. Even in greater clinics this method is not routinely performed in differential diagnosis of acidotic states. Various diseases are accompanied by a lactate emia or even by lactate acidosis. Anaerobic synthesis of lactate is an emergency reaction to supply minimum energy to tissues with insufficient oxygen supply. The main diseases complicated by increased blood lactate concentrations are shock, circulatory collapse, cardiac failure and peripheral circularoty disturbance. Additionally diabetes mellitus, septical infections, and-the most prominent situation-biguanide intoxications are complicated by an increase in blood lactate concentration.

208 hospitalized patients, nearly 80 years old, were investigated because of risk factors and complicating diseases. Hypertension (58.2%), typical myocardial infarctions (37.2%) and diabetes (45.2%) were twice often as in our comparable cases without stroke. Corresponding we found signs of left ventricular hypertrophy in more than 50% post mortem. The dimensions of heart failure by hypertension are visible in ECG indicating LVH with many dysrhythmias. Early mortality (40%) as survival time are dependent on the size of the stroke. Cardiovascular causes of death were found mainly. The differences to younger patients with brain infarction seem to be only of gradually nature and especially to refer to the more intensive damaged heart.

A retrospective study of adult congestive cardiomyopathy was carried out; the admission criteria being heart failure with cardiomegaly after the exclusion of known causes of heart failure. Coronary artery disease was excluded by forming two sub groups, one with proven normal coronary arteries at angiography or autopsy and the other with only assumedly normal coronary arteries. The results concern the study of the incidence of this disease which has been regularly seen over the last 10 years in departments with a large number of referrals of cardiomyopathy. --Professional factors are analysed to see if there is a higher incidence amongst the working classes. --Other factors are analysed by comparison with three control groups: normal, coronary and valvular disease, and diabetes which may be a predisposing factor, but not the serum cholesterol which is decreased in these patients. There is a significant association with smoking and alcoholism and the main biological sign of the latter condition, macrocytosis. This is also found in both coronary sub groups. The isolation of this alcohol factor in the genesis of congestive cardiomyopathy implies the possibility of reversing or stabilising the myocardial damage after its withdrawal, so changing the severe diagnosis associated with this disease.

Sixteen cases of lactic acidosis are reported: 7 phenformin treated diabetes, 5 cardiovascular diseases (2 myocardial infractions, 2 pulmonary embolisms, 1 heart failure). In 2 patients no etiology was found. Concomittant renal failure or liver diseases were found in respectively 9 and 4 cases. Patients presented the usual criteria of lactic acidosis: clinical, polypnea, severe hypotension (9/16), peripheral symptoms of shock (12/16), hypothermia (9/16), abdominal pain (9/16): biologically, acidosis (pH = 6,99 +/- 0,01, HCO3- = 5,9 +/- 1,5 mmol), hyperlactatemia (14,1 +/- 3,6 mmol/l) with hig lactate/pyruvate ratio (105 +/- 73), and anion gap (24,3 +/- 4,2 mmol/l). Sodium bicarbonate infusion was performed in all cases (2,5 to 42 mmol/kg). Few cases required volhemic expansion or furosemid induced diuresis. One patient was treated with extrarenal dialysis. 13 patients were alkalinised with less than 185% of estimated deficit measured from alkalin reserve: 12 died. 3 patients received 185% more than this deficit, associated with furosemid (1,8 to 12,5 mg/kg): only one patient died ten days after by casual disease, with lactatemia of 3,2 mmol/l. In spite of the small number of patients, these findings suggest that an early and massive alkalinisation, with large doses of furosemid, can improve the severe lactic acidosis prognosis.

Fibrinolysis treatment with urokinase was successfully undertaken in two patients, aged 71 and 76 years, with phlegmasia coerulea dolens. In the first case, with necrosis in the fore-foot, there was significant regression of the necrotic area, but a later limited amputation was still necessary. In the second, with severe heart failure, recurrent pulmonary emboli and hyperosmolar uncontrolled diabetes mellitus, complete healing was achieved. Venous thrombectomy was not possible in these two patients because of the duration of the thrombosis in the veins of the pelvic region, necrosis had already occurred, and the patients' general condition was so serious. The advanced age and arteriosclerotic changes argued against streptokinase treatment. Mean urokinase maintenance dosage of 1000-1500 IU/kg X h, with simultaneous administration of heparin at about 20 U/kg X h, produced no significant side-effects. Minor gastro-intestinal bleeding did not require stoppage of urokinase administration.

160 consecutive CCU-treated AMI patients below 66 yr were investigated for ventricular ectopic beats (VEB) by 6-h telemetry prior to discharge and after 1 yr. During the follow-up year 11 patients died suddenly and 20 suffered reinfarction. By stepwise discriminant analysis three independent prognostic parameters were found: (1) radiologic cardiomegaly; (2) severe VEBs prior to discharge; (3) diabetes mellitus. Previous infarct, angina, functional class II to IV, smoking, higher age and radiologic cardiomegaly were significantly more frequent in patients with VEBs prior to discharge. History of heart failure, functional class deterioration, higher age, male sex, large first infarct, VT or VF in CCU, transmural infarction, radiologic cardiomegaly were more frequent in patients with severe VEBs prior to discharge. VEB severity increased significantly during the follow-up year in survivors without reinfarction. This increase occurred in patients with previous infarction, angina pectoris, higher age and heart failure.

After a control period on a placebo, 45 patients with mild to moderate hypertension were treated with metoprolol, 100 mg twice daily alone and in free combination with chlorthalidone 50 mg daily using a double-blind crossover technique. The beta-blocker alone induced a significant fall in blood pressure; the diastolic pressure was reduced to 100 mg Hg or less in 37 of the 45 patients and to 95 mm Hg or less in 19 patients. The addition of chlorthalidone enhanced the antihypertensive effect so that in 33 patients diastolic pressure fell to 95 mm Hg or less. The drugs were well tolerated even by a small number of patients with chronic bronchitis and diabetes mellitus. None of the patients developed cardiac failure. Adding a diuretic caused a small reduction in serum potassium concentrations, and the relevance of this observation is discussed.

Platelet adhesiveness was measured in a total of 589 healthy volunteers and patients. Patients suffered from heart failure, diabetes mellitus, myocardial infarction and deep vein thrombosis have a significant higher platelet adhesiveness as healthy volunteers. The effect of the socalled stressors on platelet adhesiveness was shown in vivo; the same values of platelet adhesiveness were seen as in patients. Therefore it can be concluded that stressors constitute a risk factor in patients with altered vessel walls.

Each day, for one year, the medical records of adult patients who died in hospital were reviewed before seeing the necropsy findings. For those patients who had had chronic left or left and right heart failure, a presumptive cause was assigned on the basis of antemortem clinical data. Of 740 consecutive patients who were studied at necropsy, 90 had had chronic heart failure. In 15 patients the cause of heart failure was not apparent by clinical criteria; of these, 7 were found at necropsy to have cardiomyopathic syndrome caused by coronary artery disease. In retrospect, the presence of overt diabetes mellitus was a clue that cardiomyopathy caused by coronary artery disease was the cause of clinically unexplained heart failure; 5 of 7 patients with unexplained heart failure who were found to have this at necropsy were diabetic, whereas only 1 of the other 8 patients with clinically unexplained heart failure was diabetic (P less than 0.05). Patients in whom clinically unexplained heart failure was found to be the result of cardiomyopathy caused by coronary artery disease had multiple myocardial infarctions on pathological examination, which, with one exception, were nontransmural. By contrast, myocardial infarctions were transmural on pathological examination in each of 7 matched 'controls' with heart failure, in whom the diagnosis of coronary artery disease had been clinically apparent (P less than 0.01).

Out of 769 patients with arterial diseases, reconstructive surgery was performed on 100 limbs of 79 patients for arteriosclerosis. The overall patency rate was 59 per cent over a period of 3 to 8 years. Long-term patency was influenced by the condition of the run-off arteries, the site of the operation, and the method of surgery. No relation was found between patency rate and hypertension, cardiac insufficiency, total serum cholesterol, diabetes mellitus, or age. The survival rate was 62 per cent at 5 years and 48 per cent at 7 years. These rates were significantly poor (p less than 0.001), compared with those in the normal population. Mortality was related to the degree of hypertension, with cardiac and renal failure being responsible for 72 per cent of deaths. Aggressive reconstruction may be indicated in cases with hypertension of stage 2 or below based on the WHO classification. However, especially in patients with associated diabetes mellitus close long-term observation of the cardiovascular system is necessary.
