title: [Symptoms of a prodromal period in unstable angina pectoris].
abstract: Long-term investigation of 67 patients with unstable angina pectoris (UAP) focused on frequency of non-specific symptoms occurring within 3 days before a significant rise in the frequency of anginal attacks. Nonspecific clinical symptoms seem either to appear or enhance prior to emergence of UAP. Moreover, these symptoms in many patients repeat before each episode of UAP.
