Effect of hypnotic sedation during percutaneous transluminal coronary angioplasty on myocardial isch

12 Jul
Forty-six patients were randomized to receive drug (group 1) or hypnotic sedation (group 2) during balloon angioplasty of the left anterior descending coronary artery. Patients were continuously monitored by intracoronary and standard electrocardiograms, and heart rate spectral variability was also recorded.

Normalized units of low- and high-frequency components and the ratio of low to high frequency were measured during balloon inflations. The ST segment shifted at the first balloon inflation from 0.02 +/- 0.01 to 0.09 +/- 0.6 mm in group 1 and from 0.02 +/- 0.08 to 0.1 +/- 0.6 in group 2 mm (p <0.05).
In group 1, the low-frequency band and the ratio of low to high frequency increased significantly during the first balloon inflation (from 59 +/- 10 to 75 +/- 10 normalized units and from 2.4 +/- 1.4 to 7.3 +/- 4.7, respectively; p <0.001). The increase of the ratio of low to high frequency was significantly related to ST shift (r = 0.706; p <0.01).

In contrast, no significant variation of spectral parameters was found in group 2. The increase in cardiac sympathetic activity associated with balloon inflation and myocardial ischemia during percutaneous transluminal coronary angioplasty of the left anterior descending coronary artery was selectively eliminated by hypnosis but not by drug sedation.
