- W1968706721 abstract "Percutaneous transluminal coronary angioplasty (PTCA) was performed with initial success in 7 patients with variant angina and significant (greater than 60%) coronary stenosis. The mean degree of stenosis was reduced from 77 +/- 12% to 29 +/- 15% and the mean systolic pressure gradient from 78 +/- 18 to 25 +/- 9 mmHg. Apart from a reversible spasm in one patient, PTCA was free of acute complications. Despite long-term treatment with nifedipine, nitrates, and warfarin (patients 1 to 5) or aspirin (patients 6 and 7) restenoses occurred in 4 of 7 patients. An aortocoronary bypass was necessary in 2 patients, 3 respectively 6 weeks after PTCA because of tighter restenoses than before PTCA. Another patient underwent successful repeat angioplasty after 6 weeks and remained improved. During a mean follow-up observation of 21 months (6 to 30 months), 4 patients were asymptomatic, even without medication. In one of these patients, the follow-up angiography (6 months after PTCA) demonstrated a restenosis. These results suggest that PTCA demonstrated a restenosis. These results suggest that PTCA can be performed without a higher risk of acute complications in patients with variant angina. Although the recurrence rate is high in these patients, sustained clinical improvement was achieved in a substantial percentage of patients in our study." @default.
