Coronary angioplasty for isolated non-dominant left circumflex coronary artery disease
The study describes the clinical findings and results of coronary balloon angioplasty in 134 patients with non-dominant left circumflex coronary artery disease. The immediate angiographic success rate was 97% versus 95% for left anterior descending ( P = NS), and 90% for right coronary lesions ( P &...

Zusammenfassung: | The study describes the clinical findings and results of coronary balloon angioplasty in 134 patients with non-dominant left circumflex coronary artery disease. The immediate angiographic success rate was 97% versus 95% for left anterior descending (
P = NS), and 90% for right coronary lesions (
P < 0.002). There was no hospital mortality in the circumflex group versus 1.2% in the left anterior descending (
P < 0.01), and 0.4% in the right coronary artery group (
P = NS). Major non-fatal cardiac complications were significantly lower in the non-dominant left circumflex coronary artery patients (no new Q-wave versus 3% in the left anterior descending,
P < 0.0002, and 3% in the right coronary artery group,
P < 0.01; no urgent coronary artery bypass grafting versus 2% in the left anterior descending,
P < 0.001, and 1% in the right coronary artery group,
P = NS). The freedom from chest pain was 63% in 112 patients (84%) with follow-up data available at 24 ± 18 months, and mean angina class diminished to 0.7 ± 1.3 (
P < 0.001). Consumption of antianginal and other cardiac drugs was diminished during follow-up, and the number of patients on no such drugs increased from 5 to 32% (
P < 0.001). Restenosis was found in 19 of 32 patients with repeat coronary angiography (59%). Repeat angioplasty was required in 22 patients during follow-up and in 4 of them (18%) it was done for new lesions. Angioplasty for isolated non-dominant left circumflex coronary artery disease yields excellent immediate and long-term results. |
