[Fibrinolytic treatment of valve thrombosis. Apropos of 16 cases].

Sixteen cases of prosthetic valve thrombosis (9 mitral, 5 aortic), occurring in 14 patients, were treated by fibrinolysis. All were disc prostheses. The clinical state of the patients was very poor in 11 of the 16 cases with pulmonary oedema, low output and arrhythmias, but less dramatic in the 5 others who presented with thromboembolism and left ventricular failure. The diagnosis was made by echocardiography (9 cases), radio-cinema of the valve (9 cases) and/or angiography (4 cases). The therapy comprised Urokinase (UK) 4,500 U/kg/hour (6 cases) of Streptokinase (SK) 2,000,000 U in 10 hours (7 cases) or SK and UK at equal doses (3 cases). The outcome was assessed clinically, echocardiographically and radiologically. There were 11 definite successes, 2 partial improvements requiring surgical revision, 2 apparent successes but with massive recurrence at the 7th and 10th days, and 1 failure. Although the biological activity of SK is greater than that of UK, the clinical results were comparable with both fibrinolytic agents. Four patients had regressive embolic episodes during lysis of the valvular thrombosis. As fibrinolytic therapy was effective in 70 p. 100 of patients in this series, it could provide an acceptable alternative to surgery, especially in patients who would be poor operative risks. The management of patients after successful fibrinolysis remains divided between intensive medical follow-up or prosthetic valve replacement.

[Functional content of the electrocardiogram of coronary patients].

A comparison of the haemodynamic and electrocardiographic data was carried out in 180 coronary patients. All underwent catheterisation and coronary angiography for angina. They were divided into three main groups: 53 patients with coronary atheroma without significant stenosis; 43 patients with at least one coronary stenosis greater than 50%; 84 patients had myocardial infarction with ECG changes of transmural necrosis and coronary thrombosis (or greater than 80% stenosis). Parameters of left ventricular function (LVF), especially ejection fraction (EF), systolic work (LVESW), end diastolic pressure (LVEDP), end diastolic volume (LVEDV), myocardial mass calculated from angiography (LMV) and volumic compliance were analysed in all cases. Each patient had at least 5 ECG recordings analysed by a HP 6 calculator which determined the values of the principal numeric ECG parameters and the means of the 5 recordings. Particular attention was given to the sum of the R waves in the 12 leads (sigma R mV) and Macruz's index (duration of P/PR - P in Lead II). A satisfactory correlation was found overall between sigma R and EF (r = 0,45, p less than 0,001). sigma R was the only ECG variable related to LVF in patients without infarction. In this group of 96 patients, sigma R correlated with LVEDV (r = 0,46, p less than 0,001) with LVM (r = 0,46, p less than 0,001), with LVESW (r = 0,52, p less than 0,001). There was a discordance between angiographically measured LVM and the mass of electrically active myocardium in patients with infarction. sigma R was independent of LVM, LVEDV, and LVESW.(ABSTRACT TRUNCATED AT 250 WORDS)

[Detection of coronary atherosclerosis before 45 or 50 years of age. Value of skin biopsy].

A three year prospective study was undertaken to determine the possible relationship of coronary atherosclerosis in subjects under 50 years of age, confirmed by coronary angiography, and structural changes of the connective tissue dystrophy. The independence of the histological changes with respect to other cardiovascular risk factors was also evaluated. The study was carried out by a double blind technique between the histological and clinical results. We present our preliminary results in 88 male patients, 64 with atherosclerosis and 24 controls. Histological abnormalities were found in 81.25% of patients with atherosclerosis compared to 33.3% in the control subjects. Accelerated skin aging, a simple diagnosis, requires only light microscopy for diagnosis and seems to be the simplest and most reliable screening test. It is found in 61% of atherosclerotic patients in the general population and in 74% of coronary patients under 45 years of age, independently of other risk factors especially cigarette smoking. As a screening test for coronary atherosclerosis before 45 years of age, the sensitivity was found to be 74.2% and specificity 57.1%, the predictive value being 79.3%. Connective tissue dystrophy needs electronic microscopy and seems to be less reliable in the detection of atherosclerosis as this condition is usually found in patients over 45 years of age. However, these changes are related to atherosclerosis and not to age. This study shows that skin biopsy in the search of accelerated skin aging, enables atherosclerosis to be detected simply and reliably, independently of other risk factors. This test, by defining the individual structural risk, is a method of following the progression or regression of atherosclerosis and so help control treatment.

[Left ventricular aneurysms. Prognostic study. Operative results].

Eighty three patients with symptomatic post-myocardial infarction left ventricular aneurysms (cardiac failure: 62 cases; angina; 41 cases; ventricular arrhythmias: 37 cases; systemic embolism: 8 cases) underwent surgery between 1975 and March 1981. Preoperative investigations comprised clinical examination, left heart catheterisation and ventriculography. End systolic and end diastolic volumes, ejection fraction velocity of circumferential fibre shortening, and the akinetic surface area were calculated firstly for the whole of the left ventricle and then for the contractile zones after hypothetical resection of the aneurysm. Selective coronary angiography was carried out in 75 patients. The results were as follows: 16 perioperative fatalities (19.2 p. 100): Group IA; 14 late deaths or not improvement after surgery (17 p. 100): Group IB; 53 patients had little or no symptoms after surgery (63 p. 100), Group II. The 5 year survival rats is 69.7 p. 100. Severe cardiac failure (Stages III or IV of the NYHA Classification) is associated with a poor prognosis (33 p. 100 mortality). The hemodynamic parameters of the whole ventricle (end diastolic volume, global ejection fraction) had little or no correlation with the outcome. The ejection fraction of the contractile zones was significantly lower in Groups IA and IB (0.39 +/- 0.08, and 0.41 +/- 0.05) than in Group II (0.51 +/- 0.05), p less than 0.001). When the ejection fraction of the contractile zone exceeded 0.45, good results were obtained in 90 p. 100 of cases. The velocity of circumferential fibre shortening was also a good prognostic index (0.63 +/- 0.18 in Group IA compared to 1.10 +/- 0.09 in Group II, p less than 0.001). On the other hand, the diastolic volume of the contractile zone was very variable in all three groups. Extensive coronary artery disease not treated surgically worsened the prognosis (50 p. 100 mortality in triple vessel disease.) Seven of the 8 patients operated during the acute phase of myocardial infarction (less than I month) died, but they all had very poor hemodynamic parameters.

[Long-term treatment of severe cardiac insufficiency with captopril].

23 patients with a mean age of 62 +/- 7 years and suffering from a cardiomyopathy with severe chronic heart failure (16 patients in stage IV of the New York Association (NYHA) classification and 7 in stage III NYHA) received long term treatment with captopril (9 patients received 75 mg/day, 9 received 150 mg/day and 5 received 300 mg/day) with a follow-up of 12 +/- 9 months. Following the acute administration of captopril, there was an increase in the cardiac index (Cl) (2.76 +/- 0.56 vs 2.10 +/- 0.4 l . min-1 . m-2, p less than 0.001) between the 4th and 6th hour, a significant decrease in peripheral resistance (PR) (1416 +/- 304 vs 1094 +/- 406 dynes/s/cm-5, p less than 0.001), total pulmonary resistance (TPR) (537 +/- 228 vs 660 +/- 258 dynes/s/cm-5, p less than 0.01) and pulmonary diastolic pressure (PDP) (15.4 +/- 7.2 vs 18.6 +/- mm Hg, p less than 0.001). An early (3rd day) and reversible renal failure caused the treatment to be suspended in one patient. In the 22 other patients, a marked and lasting clinical improvement was obtained (18 patients with stage II NYHA and 4 with stage III NYHA). The beneficial haemodynamic effects persisted until the 4th month in 14 patients (Cl: 2.38 +/- 0.4 vs 2.10 +/- 0.4 l . min-1 . m-2, p less than 0.1; PR: 1828 +/- 314 vs 2054 +/- 406 dynes/s/cm-5, p less than 0.01; TPR: 526 +/- 284 vs 660 +/- 258 dynes/s/cm-5, p less than 0.01; PDP: 16.8 +/- 8.7 vs 18.6 +/- 8.6 mmHg, p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
