[The dynamics of the functional indices of the cardiovascular system in patients with a history of progressing stenocardia].
The objective of this study was an assessment of time-related course of functional indices for the cardiovascular system in patients with prior advancing angina pectoris (AAP). A close inverse relation was found out between the time-related course of threshold load and work done in load testing and changes in the number of episodes of silent myocardial ischemia, overall duration of myocardial infarction during the 24-hour period, and depth of ischemic depression of ST segment in ECG. Higher/lower tolerance to physical loads in those patients in the post-AAP period is largely related to changes in indices for intracardiac hemodynamics, such as ejection fraction and left ventricular volume and degree of signs of ventricular electrical instability.
