title: [The use of laser fluorometry of NADH in cardiology].
abstract: In this paper the first results of experimental studies of myocardial energy metabolism conducted in situ by laser fluorimetry are described. With this method the myocardial oxygen uptake is determined by measuring the fluorescence of NADH (reduced nicotinamide adenine dinucleotide). The equipment required consists of pulsed laser beams in the ultraviolet (337 nm) and visible (586 nm) spectra, very thin catheters with a single optic fibre, and an original digital data processing technique. The first applications envisaged concern: 1. pharmacological studies, notably evaluation of the protective effect of drugs against ischaemia; 2. evaluation of revascularization procedures in emergency surgery, notably assessment of reversibility of the ischaemic lesions; 3. monitoring of myocardial protection during cardiac surgery.
