Long-term beneficial effects of PTCA on segmental early relaxation in disease of the left anterior descending coronary artery.

1988

The relationship between regional left ventricular (LV) motion and global pressure relaxation of the left ventricle remains unclear. To clarify the recent concept of segmental early relaxation in coro nary artery disease, the authors in vestigated two groups of patients. In group I, all 12 patients (mean age 47±7 years) exhibited evidence of a normal heart after an extensive in vestigation. In group II, 25 patients (55±7 years) presented an isolated stenosis of the left anterior descend ing coronary artery, and they under went a hemodynamic investigation before and after (six to nine months) a durable successful percutaneous transluminal coronary angioplasty (PTCA). After all conventional …
