[Exercise tolerance after coronary stenting in patients with stable angina].
The target of our investigation was to evaluate the exercise tolerance in patients with stable angina 18 months after coronary stenting. The 165 patients with stable angina were included in research. The main group consisted of 100 patients who underwent PTCA with stenting. Control group was composed of the 65 patients who underwent conservative therapy. 73 (73%) patients of the main group and 49 (75.4%) patients of the control group had angina of III-IV functional class. Comparison of long-term results revealed that the tolerance to exercise stress in control group was considerably lower - 4.35MET than in main group - 8.58MET (p<0.05). The duration of continuous exercise stress test in control group was 7.5 min; in main group - 12.4 min. The criteria for exercise stress test discontinuation were anginous pain and/or ischemic ECG changes - 72.3%; the submaximal level of heart rate was rare - 7.7% (p<0.05). The authors conclude that the coronary stenting could significantly improve quality of life due to increase of exercise tolerance.
