[Possibilities of using the cold test in patients with unstable stenocardia]

The character of changes in autonomic heart regulation in response to the cold test has prognostic value in patients with unstable angina pectoris. The probability of development of myocardial infarction and sudden death is higher in patients with high sympathetic reactivity than in those with low sympathetic reactivity. Central hemodynamic changes have a multivariational pattern and have no prognostic value.
