Outcome of patients with stable angina pectoris treated with or without percutaneous coronary intervention.

BACKGROUND To assess the outcome of patients with stable angina pectoris treated with percutaneous coronary intervention versus medically treated patients. METHODS Eighty patients with stable angina pectoris and coronary stenosis as confirmed in coronary angiography were treated with (n = 31) or without (n = 49) percutaneous coronary intervention in our department. All patients received optimal medical therapy and were followed up for a period of 24 months. RESULTS Baseline clinical characteristics, including risk factors of coronary heart disease and coronary lesion type did not differ between the two groups (all p > 0.05). There was no significant difference in major adverse cardiac events (22.4% vs. 22.6%) during the 24 month follow-up between the two groups (p > 0.05). CONCLUSIONS Percutaneous coronary intervention did not provide extra benefit in this group of patients with stable angina pectoris receiving standard medical treatment in terms of 24 months major adverse outcomes.
