- Objective. —To evaluate the appropriateness of performing coronary angiography and revascularization in a Swedish population. Design. —Prospective population study of questionnaires and medical records. Setting. —All the hospitals in southwestern Sweden that perform coronary angiography and revascularization. Patients. —Random sample of 831 patients (with chronic stable angina) on the waiting list for coronary angiography or revascularization in southwestern Sweden in September 1990. Main Outcome Measure. —Percentage of patients referred for coronary angiography or revascularization for appropriate, uncertain, or inappropriate indications. Results. —Of the patients referred for angiography, 89% were classified as appropriate, 9% as uncertain, and 2% as inappropriate. The percentages are similar for patients referred for coronary artery bypass graft surgery and for angioplasty (91% and 86%, respectively, classified as appropriate). The majority of patients had chest pain rated as Canadian Cardiovascular Society classes II through IV (93%), despite maximum anti-ischemic therapy in 90% of these patients. Conclusions. —Few patients were referred for coronary angiography or revascularization for inappropriate or uncertain indications. The percentage of these patients who are from southwestern Sweden is similar to the percentage recently reported from New York State.

- Keywords: cardiac symptoms; chest pain; coronary revascularization; delay; ischaemic heart disease; nervous reactions; waiting list Abstract. Objectives. To describe the characteristics and the severity of symptoms amongst patients on the waiting list for possible coronary revascularization. Design. All the patients were sent a postal questionnaire for symptom evaluation. Setting. All hospitals in western Sweden. Subjects. All patients in western Sweden on the waiting list in September 1990, who had been referred for coronary angiography or revascularization (n = 904) and a sex- and age-matched reference group (n = 809). Results. More than half of the patients had daily attacks of chest pain, whereas 16% reported less than one attack per week or no pain at all. However, other symptoms such as dyspnoea, tachycardia and nervous reactions were also common and 25% of all patients used sedatives. A long waiting time for a given procedure was not associated with more pain but with more nervous symptoms such as restlessness and insomnia (P < 0.0001) and greater use of sedatives and cigarettes (P < 0.05). Conclusions. We conclude that a long waiting time for possible coronary revascularization is associated with more nervous symptoms but not with more pain.

- In a subsample of 223 patients participating in a double-blind trial with metoprolol in suspected acute myocardial infarction, body temperature during the first 5 days in hospital was recorded. Patients developing infarction had a mean temperature of 37.3°C compared with 36.8° C for those with no infarction (P < 0.001). A positive association was observed between enzyme-estimated infarct size and body temperature (P < 0.001). Patients given metoprolol had a mean temperature of 37.0° C as compared with 37.2° C in those given placebo (P = 0.03). The most marked difference between metoprolol and placebo was observed among those treated very early. We conclude that early treatment with metoprolol in suspected acute myocardial infarction appears to lower body temperature during the following days. This might reflect limitation of the infarct size.

- In 1350 patients with suspected acute myocardial infarction, serum potassium was analysed in the emergency ward. The effect of metoprolol was compared with placebo in a double-blind randomized trial. Metoprolol increased serum potassium from 4.11 ± 0.02 mmol/l to 4.27 ± 0.02 mmol/l (P<0.001) during the 1st day after hospital admission, whereas serum potassium levels remained fairly constant in patients given placebo during the same time (4.11 ± 0.02 to 4.14 ± 0.02 mmol/l; P>0.2). Similar results were obtained when analysing patients with a confirmed myocardial infarction separately. The effects appeared homogeneously distributed in subgroups related to sex, clinical history, infarct site, infarct size and delay time from onset of symptoms to start of treatment. We conclude that early treatment with the beta-1-selective blocker metoprolol in patients with suspected acute myocardial infarction increases serum potassium.

- The frequency of subjective cardiac and psychological complaints among men and women a year after a confirmed diagnosis of myocardial infarction (MI) were compared. Among 660 survivors, 595 patients completed mailed questionnaires at home one year after the MI. There were 421 men, mean age 67.1±10.7 years, and 174 women, mean age 72.1±10.6 years. Controlling for the significantly higher mean age among the women, the latter more often had a previous history of angina pectoris, 54.6% (P≤0.05) versus 42.9%, and heart failure, 24.7% versus 13.5% (P≤0.01). Despite these facts, the women were significantly less often referred to CCU, 82.2% versus 91.7% (P≤0.05). One year after the MI, controlling for differences in age and co-morbidity, women reported significantly higher frequencies of psychological and psychosomatic complaints, including sleep disturbances. These differences may have clinical implications for diagnosis and treatment of women with coronary heart disease.
