Blood-carboxyhaemoglobin (COHb) levels were studied in 343 healthy male cigarette smokers aged 35-64. The mean COHb level was 30% higher in the 248 men who smoked unventilated filter cigarettes than in the 41 men who smoked plain cigarettes, after adjusting for the number of cigarettes smoked (P less than 0.001). This result was consistent with the carbon-monoxide (CO) yields of these cigarettes: on average, the unventilated filter cigarettes had yields 25% higher than the plain ones. The mean COHb level was 7% higher in the 54 men who smoked ventilated cigarettes than in men who smoked plain cigarettes. Although this difference was not statistically significant, it was in the opposite direction to the result which might have been expected on the basis of the CO yields of these cigarettes: on average the ventilated filter cigarettes had yields 21% lower than the plain ones. The medical implications of these results are uncertain. COHb levels of 3-4% or more can exacerbate angina pectoris and intermittent claudication, and it is, therefore, of concern that COHb levels are higher in smokers of filter cigarettes than in smokers of plain cigarettes. However, any assessment of risk associated with either type of cigarette should take account of the observation from other studies that filter cigarettes are associated with a lower mortality from lung cancer than are plain cigarettes.

This prospective, Human Subjects Committee and Ethics Committee approved investigation was performed to determine if coronary angioplasty (PTCA) might be a reasonable alternative revascularization method for unstable angina patients thought to be at high risk for operative (CABG) mortality. Between March 1990 and October 1991, thirty-four consecutive patients with medically refractory rest angina were deamed to have high risk of surgical mortality and underwent PTCA without surgical backup. Predicted operative mortality was calculated for each patient based upon the VA Surgical Risk Assessment model. Angioplasty of 52 vessels was attempted. Reduction in lumenal narrowing to < 50% and improved angiographic flow was obtained in 47 vessels. There were four complicating infarctions. One death occurred in the lab, and three patients with unsuccessful angioplasty died within 30 days of pump failure. Relief of angina occurred in 30/34. Thirty patients were discharged home. In follow-up from 1 to 12 months, there have been 2 late sudden deaths at 4 months and 9 months, 1 death from lung cancer; 4 patients have stable exertional angina; 2 are awaiting heart transplant but are pain free, and one patient who had PTCA during cardiogenic shock from acute myocardial infarction had elective coronary artery bypass surgery. There have been no late myocardial infarctions. The observed angioplasty 30-day mortality of 11.8% (95% confidence limit 1% to 22.6%) compares favorably with the predicted operative mortality of 23.8% for this group. This prospective but non-randomized series supports the concept that balloon angioplasty may be a reasonable alternative to surgical intervention in some patients with unstable angina and high risk for surgery. A prospective randomized trial is warranted.

Based on obligatory notifications from pharmacies to the National Board of Health about prescription of strong analgesics as well as questionnaires to the prescribing doctors, the occurrence and causes of pain requiring strong analgesics outside hospitals were analysed over a period of one month in Denmark in a limited population (480,000), corresponding to nearly 10% of the Danish population. During one month, strong analgesics were prescribed to 0.2 per cent of the population. The commonest acute conditions were back pain (23%) and trauma (17%). The commonest recurrent acute conditions were headache (25%) and angina pectoris (17%). The commonest chronic non-malignant conditions were back pain (29%) and pancreatitis (7%). The commonest malignant conditions were lung cancer (20%) and colorectal cancer (14%). The commonest conditions indicated under the chronic pain syndrome were headache (33%) and back pain (13%). Conditions requiring strong analgesics reflect to some extent the distribution of painful conditions in the general population.

The records of 598 patients undergoing a thoracic surgical procedure for lung cancer from 1975 through 1989 were reviewed for occurrence of cardiac arrhythmias and myocardial ischemic events. Atrial tachycardias occurred in 16% (94/598); atrial fibrillation was preponderant (87%), followed by supraventricular tachycardia and atrial flutter. Patients with recurrent episodes of dysrhythmias had a significantly higher mortality rate than those without episodes or with a single episode only (17% versus 2.4%; p less than 0.01). Transient ischemic electrocardiographic changes were documented in 23 patients (3.8%) and myocardial infarction in 7 (1.2%). An abnormal preoperative exercise test result and intraoperative hypotension were strongly associated with both dysrhythmia and ischemia (p less than 0.01). Pneumonectomy, ischemic changes on the electrocardiogram, and cardiac enlargement were also associated with arrhythmias (p less than 0.01). A weaker association (p less than 0.05) was found between postoperative arrhythmias and old myocardial infarction (greater than 6 months), arterial hypertension, and heart failure. Pulmonary function had no predictive value in this respect. A history of angina or old myocardial infarction was predictive of transient postoperative myocardial ischemia but not myocardial infarction. Despite improved anesthetic and monitoring techniques and more frequent use of the intensive care unit postoperatively in the last decade, the incidence of arrhythmias after thoracotomy has not decreased. More effective prevention is needed, particularly for patients with defined preoperative and perioperative risk factors.

We treated 34 primary lung cancer patients with chemotherapy of cisplatin and etoposide. There were 2 cases of CR (15%) and 8 cases of PR (61%) out of 13 cases of small cell lung cancer. No case of CR and one case of PR (5%) were obtained out of 21 cases of non-small cell cancer. Side effects were leukopenia, increase of BUN and creatinine, angina pectoris, supraventricular premature contraction, and renal failure. WBC reached nadir on day 15 on average. When we repeated this regimen, we encountered 3 cases of acute myocardial infarction, and it was useful for small cell lung cancer.

This study analyses the long-term prognosis of 210 patients with coronary spasm documented at coronary angiography. All patients with a previous history of myocardial infarction or who had undergone coronary angioplasty were excluded. The average follow-up was 55 months and only 11 patients were lost to follow-up. The actuarial survival figures showed the 1 year, 2 year and 5 year survival rates to be 95, 92 and 89 per cent respectively. Extracardiac mortality was mainly related to smoking (lung cancer, laryngeal cancer, etc.) and was higher than cardiac mortality. More than half of the cardiovascular events (sudden death, myocardial infarcts) occurred during the first year of follow-up. Ten patients (4.7%) died suddenly. The predictive factors of this event were: previous syncopal episodes or syncopal angina due to coronary spasm, percritical arrhythmias and the documentation of multiple spasms at coronary angiography. Myocardial infarction was observed in 10.6 per cent of patients. Only those with significant coronary arterial lesions developed this complication. At the end of the follow-up period, 75 per cent of patients were asymptomatic or had only atypical chest pain. No significant differences were observed between the two groups treated medically, by aortocoronary bypass or by the association of coronary bypass and plexectomy with the exception of non-lethal myocardial infarcts being significantly less common in patients treated medically. Therefore, the long-term prognosis of patients with coronary spams is relatively satisfactory.

A 64-year-old lung cancer patient combined with angina pectoris was admitted to our hospital. Chest roentgenogram showed a coin lesion in the left upper lobe. Broncho-fiberscopic examination proved adenocarcinoma. Coronary angiography revealed 90% stenosis of the left circumflex artery. Percutaneous transluminal coronary angioplasty (PTCA) was done and resulted in success. Eight days after PTCA, left upper lobectomy for lung cancer was undergone. Postoperative course was uneventful. Compared with coronary artery bypass grafting, PTCA was very useful for the patient having malignant disease combined with angina pectoris because of little surgical stress and no delay of operation.

The results of the catamnestic study of case reports and records of postmortem examination of 102 patients with bronchial asthma (BA) aged 47 to 88 years who died at a general hospital during 1976-1988 indicate that in the overwhelming majority of cases, there took place death "with asthma" rather than death "from asthma". At the same time the dominant pathology was coronary heart disease (acute coronary failure, myocardial infarction, progressive heart failure associated with atherosclerotic and postinfarction cardiosclerosis). Emphasis is laid on the fact that according to the autopsy data, the rate of the recognized stenosing atherosclerosis of the coronary arteries considerably exceeded the number of cases of coronary heart disease documented clinically (typical angina pectoris of effort, significant macrofocal myocardial infarction). The characteristic features of the group under observation included an unexpectedly frequent combination of BA and malignant neoplasms (24 cases), including lung cancer in 13 of these cases.

To determine the outcome of patients with carotid transient ischemic attacks (TIAs) and normal cerebral angiograms, we assessed 68 patients (40 men, 28 women) aged 24-72 (mean 53.5) years for recurrent TIAs and strokes and for the development of cardiac disease over 2-6 (mean 4.4) years. All but one patient had a follow-up interview in early 1987; that patient had died of an unrelated cause (lung cancer) 18 months after the presenting TIA. The diagnosis was changed at the follow-up interview in three patients (multiple sclerosis, meningioma, migraine). Among the 64 remaining patients, at admission cranial computed tomography had shown cerebral infarction in 11 of 64, two-dimensional echocardiography had been abnormal in nine of 61, Holter monitoring had been abnormal in eight of 45, and twelve-lead electrocardiography had been abnormal in three of 64. Two patients had abnormalities on both echocardiography and Holter monitoring. At the follow-up interview of the 64 remaining patients, TIAs had recurred in nine and three had developed a completed stroke; cardiac disease (angina in seven, myocardial infarction in four) was noted in 11 patients. Findings from cardiac investigations on admission in the nine patients with recurrent TIAs had been abnormal in six and normal in three; all three patients who developed a stroke had had abnormal cardiac findings. Overall, further neurologic or cardiac events occurred in 12 of 46 patients (26%) with normal and in 10 of 18 patients (55.5%) with abnormal findings on admission (p less than 0.01). In the presence of normal angiograms, extensive cardiac investigations may help predict the outcome of patients with TIAs.

Possible adverse health effects of breathing environmental tobacco smoke include lung cancer, respiratory illnesses in young children, decreased pulmonary function, decreased lung growth, allergy to tobacco, and exacerbation of angina. These effects are reviewed to aid informed discussion on this health issue. Some of the constituents of tobacco smoke are found in the home, the outdoor environment, and the workplace in permissible concentrations and are considered unlikely to cause ill health. A double standard, one in the workplace and another for the public, may be evolving for acceptable health risks.
