Patients with chronic conditions, such as heart failure, swim regularly and most rehabilitation exercises are conducted in warm hydrotherapy pools. However, little is known about the acute effects of water immersion (WWI) on cardiac haemodynamics patients failure (CHF). Seventeen CHF (NYHA I II; mean age 67 years, 88% male, left ventricular ejection fraction 33%) 10 age-matched normal subjects were immersed up to neck a pool (33–35 °C). Cardiac measured non-invasively, echocardiography was performed at baseline, during WWI, 3 min after kicking supine position emerging. In CHF, compared WWI immediately increased stroke volume (SV, ± standard deviation; from 65 21 82 22 mL, p < 0.001), output (CO, 4.4 1.4 5.7 1.6 L/min, 0.001) index (CI, 2.3 0.6 2.9 0.70 L/min/m², decreased systemic vascular resistance (from 1881 582 1258 332 dynes/s/cm5, systolic blood pressure (132 115 23 mmHg, 0.001).
