Haemodynamic observations during spontaneous angina pectoris.

Central haemodynamics during oxygen breathing in angina pectoris.

Lecerof, H. (1974). Thorax, 29, 673-677. Central haemodynamics during oxygen breathing in angina pectoris. The haemodynamic effects of breathing 100% oxygen have been studied by right heart catheterization at rest and during bicycle exercise in nine male patients with coronary heart disease. Oxygen breathing produced no significant haemodynamic benefit during angina pectoris induced by physical...

Left ventricular performance and related haemodynamic changes in Prinzmetal's variant angina pectoris.

Attacks of Prinzmetal's variant form of angina pectoris are spontaneous, recur cyclically, and present unequivocal electrocardiographic alterations: they are ideal for a detailed haemodynamic study.Four patients with this form of angina were investigated. In each of them episodes occurred of electrocardiographic abnormalities either accompanied or unaccompanied by pain. During the same session,...

Similarities of ergonovine-induced and spontaneous attacks of variant angina.

Ergonovine has been shown to provoke attacks of variant angina, but a question remains whether spontaneous and ergonovine-induced attacks of variant angina are similar. Seven patients with variant angina undergoing cardiac catheterization were studied during transient episodes of spontaneous and ergonovine-induced rest angina with ST-segment elevation. Clinical, electrocardiographic, left ventr...

The haemodynamic response to myocardial ischaemia in ambulant patients with variant angina.

The haemodynamic response to myocardial ischaemia in patients with variant angina during ambulatory activity is unknown. Ambulatory pulmonary artery pressure monitoring with a transducer tipped catheter and simultaneous frequency modulated electrocardiograms was used to assess changes in left ventricular function in five male patients (mean age 51.8 years) during variant angina; four patients h...

Clinical, electrocardiographic, and haemodynamic effects of long-term use of propranolol in Prinzmetal's variant angina pectoris.
