Decreasing length of stay in the hospital by coronary angiography with 5-French catheters

The use of 5-French (F) coronary angiography catheters as opposed to 7-F may reduce arterial injury at the puncture site. Therefore, a decrease in time to recuperation after coronary angiography with the Judkins technique seems possible. In 199 patients undergoing coronary angiography with 5-F catheters, management, imaging, and complications were investigated. In 18 patients the diagnosis of a valvular defect was confirmed; in 128 patients coronary artery disease (lesions greater than 70%) was found. Three patients had idiopathic dilative cardiomyopathy. Coronary lesions of less than 70% with normal left ventricular function were found in 50 patients ("normals"). After coronary angiography with 5-F catheters bedrest was recommended for 4 h, as compared to 24 h after a 7-F catheter procedure. Successful coronary artery imaging with 5-F catheters was achieved in 168 patients (84%). In 31 patients (27 coronary artery disease, 1 aortic stenosis, 3 normals) selective imaging was not achieved, and the 5-F catheter had to be replaced by a 7-F catheter. Aortic (systolic 147 +/- 24 vs 132 +/- 20 mm Hg, p = 0.002; diastolic 74 +/- 13 vs 70 +/- 11, p = 0.05) and left ventricular pressures (systolic 149 +/- 26 vs 131 +/- 20 mm Hg, p = 0.001; enddiastolic 18 +/- 8 vs 14 +/- 8 mm Hg, p = 0.035) were higher in this group, whereas no relations to age, sex, and diagnosis emerged.(ABSTRACT TRUNCATED AT 250 WORDS)
