Long-term results of delayed balloon coronary angioplasty (DBCA) in myocardial infarction (MI) survivors were studied by the following end points: general and cardiac lethality, repeated MI, renewal of anginal attacks, life-threatening arrhythmia, symptoms of circulatory deficiency, rate of hospitalization during 5 years of follow-up. 57 patients who had undergone DBCA 3 weeks--6 months after MI were analyzed retrospectively. Overall and cardiac lethality was 8.8%. For 5 years of follow-up renewal of angina was seen in 70.1% patients, repeated MI developed in 10.5%, life-threatening arrhythmia and conductivity disorders were revealed in 5.3%, chronic cardiac failure--in 22.8% patients. DBCA in survivors of macrofocal MI in combination with current drug therapy to improves significantly long-term prognosis and reduces twice 5-year lethality after Q-wave MI.
