Effect of hypnotic sedation during percutaneous transluminal coronary angioplasty

04 Apr
Researchers from Poliambulanza Hospital in Brescia, Italy, randomized 46 patients to receive either medical sedation (group 1) or hypnotic sedation (group 2) during percutaneous, transluminal coronary angioplasty of the left anterior descending coronary artery.

Intracoronary and standard electrocardiograms were continuously registered, and heart rate spectral variability was measured. 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.

In other words, 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.
