Outcome Measures

Primary Outcomes (1)

  • Change in Pulmonary arterial pressure

    Pulmonary arterial pressure will be measured during RHC with and without parallel Inspiratory Muscle Training (IMT). Changes related to IMT will be assessed.

    During RHC with and without parallel IMT

Secondary Outcomes (5)

  • Change in Pulmonary Capillary Wedge Pressure

    During RHC with and without parallel IMT

  • Change in Cardiac output

    During RHC with and without parallel IMT

  • Change in Cardiac index

    During RHC with and without parallel IMT

  • Change in Stroke volume index

    During RHC with and without parallel IMT

  • Change in Stroke volume

    During RHC with and without parallel IMT

Study Arms (1)

RHC and IMT

EXPERIMENTAL
Other: RHC and IMT

Interventions

Eligible patients subjected to RHC will be instructed on how to do RMT using the Threshold IMT® two days in advance. RMT will be conducted with 20-30% of individual inspiratory muscle strength, which will be measured beforehand. A single training session consists of 7 cycles with 2 min inspiratory training each, followed by a 1 min break (total duration 21 min). The actual intervention consists of inspiratory muscle training (IMT) during right-heart catheterization for at least 2 min or as long as is necessary to measure all specified parameters.
