Vasospastic angina assessed by hyperventilation-thallium-201 myocardial scintigraphy.

The response to prolonged hyperventilation (HVT) was evaluated by electrocardiography (HVT-ECG) and thallium-201 myocardial scintigraphy (HVT-Tl-Sc) in 40 patients suspected of vasospastic angina. Both tests showed ischaemic changes in 16 patients and no changes in 20 patients. Two patients had abnormal HVT-ECG and normal HVT-Tl-Sc, and the reverse combination was found in two patients.

One-year experience with a low-fat, low-cholesterol diet in patients with coronary heart disease.

For 3 mo, 14 patients with severe coronary heart disease and serum cholesterol levels of 6-9.5 mmol/l were treated with a diet containing 10% of total energy from fat and less than 100 mg cholesterol per day. Serum cholesterol and serum low-density lipoprotein (LDL) cholesterol were reduced by 33% and 41%, respectively, while serum high-density lipoprotein (HDL) cholesterol and serum triglycerides did not change significantly.

Exercise stress testing in angina patients with positive response to hyperventilation testing: influence of the coronary artery tone.

We studied the exercise stress test and the coronary artery tone in two groups of angina patients with comparable coronary atherosclerosis. Group I (20 males and 5 females, mean age 53.5 years) with a positive, and group II (22 males and 3 females, mean age 52.

The prognosis for patients referred with suspected acute myocardial infarction.

A follow-up investigation of the prognosis of 381 patients admitted with suspected acute myocardial infarction (AMI) has been carried out in respect of later AMI or death. During hospitalization the patients were divided into groups with particular attention to patients with no demonstrable myocardial infarction but with ischaemic heart disease (non-AMI) and patients with confirmed AMI. All patients were subjected to follow-up for 43 months (range 37-54).

Variation of serum lipoproteins in postmyocardial infarction patients treated with verapamil or placebo.

The effect of verapamil on plasma lipids and lipoproteins was studied in 64 patients taking part in a double blind controlled trial of verapamil versus placebo in post myocardial infarction. During a six month treatment period no significant difference was seen in plasma cholesterol, triglycerides, high density lipoproteins or low density lipoproteins.
