[Cardiovascular effects of sodium chloride bath and underwater shower in coronary ischemia]

Two hundred and eighteen patients (209 males and 9 females, mean age 57.1 +/- 0.6 years) with I class coronary ischemia were subdivided into two groups of 109 subjects each. Group I received NaCl baths, group II underwater massage-showers. On days 2-3 and 23-24 of treatment all underwent incremental stress testing until exhaustion. In group I, only subjects with moderate maximal muscular power improved their stress endurance. In group II, stress endurance significantly improved in all subjects: all hemodynamic indices (cardiac, output, stroke volume, systemic vascular resistances) showed variations indicative of improved cardiorespiratory function and peripheral blood supply.
