A case of highly disabling orthostatic hypotension: when an integrated cardiac rehabilitation approach makes the difference.

Summary: Orthostatic hypotension (OH) is a disabling condition accompanying several diseases. It has increased morbidity and mortality, and limited chances of treatment. We report a case of a patient with stable ischemic heart disease and severe OH unresponsive to usual care. A baseline 75° head-up tilt test (HUT) was positive for symptomatic OH, i.e. pre-syncope with a systolic arterial pressure drop of 35 mmHg. On top of optimal treatment, ivabradine was started. Symptoms improved within 24 hours. At a repeated HUT, the patient could tolerate the up-right position up to 25 minutes. He was able to undergo an individualized training program with further amelioration of quality of life. Thereafter, titration of ACE inhibitors became possible. Lasting benefits were present at a 6-month follow-up. To our knowledge, this is the first reported case of successful use of ivabradine to integrate cardiac rehabilitation for management of a highly disabling OH.
