We report the clinical features and the results of investigation and surgery in 20 patients with significant left main coronary artery stenosis. All had moderate to severe angina; 8 had pain at rest. Three had dyspnoea as a major symptom. The electrocardiogram was abnormal in 17, with evidence of previous myocardial infarction in 10. Of the 11 patients exercised, 8 developed chest pain. Nine patients had a normal left ventriculogram. At coronary angiography all patients had major disease elsewhere in addition to the left main coronary artery stenosis. There were no deaths or major complications associated with this investigation. One patient was unsuitable for surgery because of diffuse left ventricular hypokinesia, one had a fatal myocardial infarction while awaiting operation, and there was one preoperative death. Sixteen of the 17 surgical survivors are free from angina. There has been a significant improvement in the maximum exercise capacity in the 10 patients who had pre- and postoperative exercise tests.

The clinical, left ventricular and coronary angiographic data, and the technetium-99m stannous pyrophosphate (99mTc-PYP) myocardial scintigraphic results are presented in 31 patients with unstable angina pectoris. One-third of these patients had positive 99mTc-PYP myocardial scintigrams in a pattern suggesting limited and diffuse subendocardial necrosis. The positive 99mTc-PYP myocardial scintigrams occurred without diagnostic electrocardiographic and cardiac enzyme changes suggestive of myocardial infarction; positive scintigrams seemed to occur more commonly in patients with continuing pain after admission and in those without previous history of myocardial infarction. The positive 99mTc-PYP myocardial scintigrams did not correctly predict coronary anatomical patterns except that positive scintigrams occurred only in patients with coronary artery disease. Neither did the positive scintigrams necessarily occur in that group of patients with the poorest ventricular function though the 2 patients with the lowest ejection fractions both had positive 99mTc-PYP myocardial scintigrams. Finally, when positive 99mTc-PYP scintigrams are the only evidence suggestive of limited subendocardial infarction in patients with unstable angina pectoris, they do not appear to have any prognostic significance in terms of longevity or response to pharmacological or surgical therapy, though the follow-up period so far is short.

The natural history of new and worsening angina pectoris was studied in 251 men aged under 70 years. Most were ambulant and all were referred by selected general practitioners to a special hospital clinic over two and a half years. Heart attacks developed in 39 patients, nine of whom died. Seventy-two per cent of the attacks occurred within six weeks of the onset or worsening of angina. Of the 212 patients who did not suffer myocardial infarction and who were clinically reviewed six months after their first attendance 66 had been pain free for the previous three months and 14 had experienced only infrequent attacks of angina. Of the 128 men aged under 65 years who were previously in employment 81% had returned to full-time work six months after their first attendance. A discriminant function analysis using many variables was made to develop a predictive index that would allow patients with new or worsening angina who were likely to develop serious cardiac complications to be identified. This did not prove possible, and the only predictive factor of significance was an increased cardiothoracic ratio. The syndrome of new and worsening angina has a low risk of early death, and many patients are symptom free six months later. In general, emergency coronary arteriography and surgery is not indicated.

Experience with 1000 cases of aorto-(bi)femoral bypass is presented evaluating factors influencing the overall patency rate and late survival, over a period of 25 years. There were 820 cases with bilateral and 180 with a unilateral bypass. Mortality was 3.3% and death rate 39.4%. Re-do procedures have been excluded. Operative indications were for stage I disease (moderate claudication) (17.6%), stage II (advanced claudication) (53.2%), stage III (rest pain and/or pregangrenous changes) (22.7%) and stage IV (gangrenous tissue loss (6.5%). Myocardial infarction was the predominant cause of late death in 192 cases (48.7%), followed by cancer in 48 (13%), cerebrovascular disease in 43 (11%), chronic lung disease with cor pulmonale in 15 (3.8%) and miscellaneous causes in 52 (13.2%) of patients. The cause of death was unknown in 31 (7.8%) cases. Co-existent peripheral arteriopathy (PAD) noted in 377 (37.7%) patients, was found to be a major determinant of late graft patency. Carotid artery disease and renovascular hypertension were corrected surgically, prior to aorto-femoral bypass in the 5.6% and concomitantly in 4.2%. Coronary artery disease in 273 (27.3%) patients and hypertension in 269 (26.9%), had a great influence on late survival as did age and smoking habits. Endarterectomy together with profundaplasty was carried out in 162 (16.2%) instances. It was our policy to extend the graft limb over the profunda femoris and in cases with co-existent superficial femoral artery disease 208 (20.8%). In 630 (63%) instances, the distal anastomosis was performed at the level of common femoral artery. Immediate graft patency was obtained in 99.3% of the cases. Late patency rate for stages I and II at 5, 10 and 15 years was 82%, 76% and 72% respectively. Following secondary operation for graft occlusion, the 15 year patency was increased to 71%. Co-existent superficial femoral disease can be alleviated by appropriate concomitant profundaplasty. Amputation rates were 0.8% for stage II, 1.5% for stage III and 2.4% for stage IV disease. Twenty year life table analysis showed a reduced survival (54%), in comparison with normal population (77%).

Fifty patients (38 men) with unstable angina pectoris defined by: pain lasting > 15 minutes+percritical electrocardiographic changes+significant coronary narrowing on coronary angiography (Coro 1) performed within 24 hours, were treated in a double blind protocol with rt-PA (n = 25) 100 mg/90 minutes (10 mg bolus + 90 mg/90 minutes or placebo (n = 25). All received effective intravenous heparin and intravenous nitrates. Calcium antagonists and betablockers were prescribed in half the cases. Aspirin (100 mg orally per day) was prescribed after control coronary angiography (Coro 2) performed 24 +/- 6 hours after starting treatment. Qualitative and quantitative analysis (CAESAR system) was centralised. There were no differences in the angiographic findings between the two groups. Intracoronary thrombosis was observed in 43% (rt-PA) and 44% (placebo) in Coro 1 and in 17% and 28% in Coro 2. The incidence of myocardial revascularisation procedures was similar in the two groups: angioplasty: 12 (rt-PA) and 13 (placebo); coronary bypass surgery: 5 (rt-PA) and 6 (placebo). Seven patients developed myocardial infarction (5 rt-PA, 2 placebo), one of whom died of cardiogenic shock (placebo). Eighteen patients had haemorrhagic complications (14 rt-PA, 4 placebo; p < 0.002) mainly at the puncture sites (12/14, 3/4). Spontaneous haemorrhage occurred in 7/25 (28%) of patients on rt-PA (haematuria 3, gastrointestinal haemorrhage 2, haematuria + gastrointestinal haemorrhage 1, epistaxis 1) and in 1/25 patients on placebo (gastrointestinal haemorrhage) This study shows that intravenous thrombolysis with rt-PA in severe unstable angina pectoris doe not modify the clinical outcome or the angiographic lesions but exposes patients to a high risk of haemorrhagic complications.

Vasospasms are inappropriate constrictions of small vessels leading to a variety of clinical pictures depending on the location of such spasms. Although the pathophysiological mechanism is not yet well understood, we know some factors able to provoke spasm in patients with appropriate predisposition like hemorrhage, coldness, emotional stress and others. Such vasoconstrictions provoke normally relative mild symptoms like cold fingers, or pain as in variant angina and in only very rare cases, to irreversible structural damage such as myocardial infarction. There is not much known about the involvement of the eye in vasospastic disorders. Retinal migraine is a known entity but occurs quite seldom. If one looks for it, one can often find (mostly reversible) visual field damage in patients with vasospastic disorders. This might be a sign of a reversible functional damage most probably due to a decreased circulation in the optic nerve head or the surrounding choroid. In most of these patients the optic nerve head looks normal, sometimes slightly pale. In patients with the so-called normal-tension glaucoma however, the prevalence of vasospastic disorders, is very clearly increased. This leads to the hypothesis that recurrent vasospasm in the eye may, in some cases, finally lead to structural damage, presenting itself phenomenologically as normal-tension glaucoma. Therefore treatment or selected normal tension glaucoma patients with calcium-channel-blockers is helpful, as has been proven in prospective studies.

When restorative treatment was performed in 51 patients with myocardial infarction, 3 groups were identified, each including 17 persons. The main group comprised those whose rehabilitation had been achieved by early physical trainings with coronary active agents; the first control consisted of those who had gone in for physical exercises and received antianginal drugs, the second control group included those whose rehabilitation had been conducted by the well-known procedures (therapeutical exercises, graded walking, nitrates, beta-blockers, calcium antagonists). The treatment resulted in improvement in the functional status of patients from the main and the first control groups as compared to those from the second control group. It is concluded that in patients with myocardial infarction without pain syndrome in the subacute period of the disease the efficiency of restorative treatment may be enhanced by using early individualized physical trainings without application of coronary active drugs.

111 patients below 70 years old, with the first acute myocardial infarctions, 6 hours since the pain occurred--have been treated with streptokinase i.v. In 102 patients we obtained full curve of CK-MB activity. Early peak of CK-MB activity < 15 hours after onset of symptoms we have observed in 59 patients, and late peak of CK-MB activity > 15 hours in 43 patients. There was not any significant statistics differences between early and late groups in frequency of: early ventricular fibrillation (< 48 hours), complex ventricular arrhythmia (in 21 day), heart failure and in-hospital mortality. 1 patient died in hospital in early group and in late group also died 1 patient. The follow-up period was from 10 to 48 months (av. 26 +/- 13). 100 patients left the hospital and the full informations we have obtained in 97 cases. No one died in that time. In the group with early peak CK-MB activity we observed more often the unstable angina and the new myocardial infarction (21%) than in the group with late peak of CK-MB activity (15%), but these differences were nonsignificant. In conclusion our results don't confirm that the early peak of CK-MB activity is the positive risk factor of unstable angina and the new myocardial infarction.

450 successive celioscopic cholecystectomies (May, 1990-April, 1992) are reported for 312 cases of uncomplicated gallstone (69%) operated electively and 138 cases operated in emergency, including 120 cases of acute cholecystitis, 17 cases of biliary pancreatitis and 1 case of angiocholitis. Immediate conversion into laparotomy was required in 10 cases (2.2%) either for technical reasons (1.1%) or because of lithiasis of the common bile duct (1.1%). The stay in hospital lasted an average of 2.2% days for elective admission and 3.3 days for emergent admission. The average operating time was 65 minutes (75 minutes until May, 1991, and 55 minutes between May, 1991 and April, 1992). Preoperative retrograde cholangiography was performed in 67 cases and intraoperative cholangiography in 16 cases. Second surgery was required for suture in one case because of cholerrhagia in a secondary duct of the gallbladder bed. This cholerrhagia would not have been amenable to simple aspiration. One patient (0.2%) died of myocardial infarction at D + 10. Complications include 4 cases of pulmonary embolism, 3 cases of cystic biliary fistula without second surgery and 4 cases of umbilical hernia. A more peculiar case is that of a patient admitted 5 months after surgery for gangrenous acute cholecystitis. This patient was admitted for fever and epigrastric pain. He had a very low-flow duodenocutaneous fistula of uncertain origin. This patient was not operated again. This may not be a complication connected to celioscopic surgery. Celioscopic cholecystectomy is superseding conventional cholecystectomy. Surgeons' efforts should strive at eliminating operative errors, reducing postoperative morbidity, improving techniques and instruments, teaching celioscopic surgery and extending its indications to other intraabdominal operations.

On exercise testing after an episode of unstable coronary artery disease (CAD; unstable angina or non-Q-wave myocardial infarction), a proportion of patients show ST-segment depression, indicating myocardial ischaemia, but do not report concomitant symptoms of angina. Treatment of such "silent" ischaemia aims mainly to reduce the risk of subsequent cardiac events. We have studied the effect of low-dose aspirin in patients with myocardial ischaemia defined at the predischarge test as silent (though patients might have had symptomatic ischaemia at other times) or symptomatic. 740 men with unstable CAD aged 70 years or less underwent symptom-limited exercise testing before hospital discharge; 144 showed ST depression without pain and 230 ST depression with simultaneous chest pain. Of the silent ischaemia group, 67 were randomly assigned placebo and 77 aspirin (75 mg daily); the corresponding numbers in the symptomatic group were 125 and 105. Angina symptoms were less common in the silent than in the symptomatic ischaemia group both before inclusion and during follow-up, and a greater proportion of the silent ischaemia group were included because of myocardial infarction. In both ischaemia groups aspirin treatment reduced the risk of subsequent myocardial infarction or death by 3 months' follow-up (silent 4% of aspirin-treated vs 21% of placebo-treated patients, p = 0.004; symptomatic 9% vs 18%, p = 0.05); at 12 months' follow-up a significant benefit of aspirin was still apparent in the silent ischaemia group (9% vs 28%, p = 0.005) but not in the symptomatic group (13% vs 22%, p = 0.109). Low-dose aspirin reduced the risk of subsequent myocardial infarction at least as well in silent as in symptomatic myocardial ischaemia. Since improvement of outlook is the main treatment objective in symptom-free patients, aspirin should be a mainstay of their treatment.
