Key result
Graded immersion and swimming in patients with moderate to severe MI or CHF resulted in abnormal pulmonary pressures and left ventricular overload compared to rest or cycle ergometry.

Does water immersion and swimming cause adverse hemodynamic responses in patients with moderate to severe MI or CHF?
Water immersion and swimming induce acute hemodynamic deterioration, including increased preload and left ventricular overload, in patients with moderate to severe MI or CHF.
Meyer et al. (2004) conducted an observational in Myocardial infarction (MI) and chronic congestive heart failure (CHF). Graded immersion and swimming vs. Supine cycle ergometry or rest was evaluated on Changes in cardiac dimensions and central hemodynamics. Graded immersion and swimming in patients with moderate to severe MI or CHF resulted in abnormal pulmonary pressures and left ventricular overload compared to rest or cycle ergometry.
