There was a patient who was coming to Cardiac Rehab following a cardiac bypass procedure and she was always fatigued and exhausted – they thought her blood pressure medications were titrated possibly too high and was actually sent to the ED without exercising one day due to being too tired and consistent light headedness. Patient actually required stability with walking due to lightheadedness. Maggie Sullivan did some critical thinking and asked about other things that could be influencing fatigue – she asked about diet and the patient was following the cardiac diet that we recommend to all cardiac patients very closely. Restricting sodium intake to a very small amount. Maggie concluded that she was possibly suffering from hyponatremia (not enough sodium in her diet) due to the common information we provide our patients to be on a sodium restricted diet after their cardiac events. She followed up with Ashley, our dietitian to find out that about 20% of the population does not do well on a very low sodium diet, something that was not known to our staff members. After having this discussion with the patient – she encouraged the patient to increase her sodium intake to 1500mg/day and the patient had a remarkable recovery. Significant increase in energy levels, able to walk for 35 minutes on a treadmill and significant improvement in mood – in just 48 hours after increasing sodium intake!! And most importantly, no lightheadedness. This was a great learning point for our entire staff as some people did not like that Maggie was encouraging increased sodium to a cardiac patient. But she was right…per usual! She makes this kind of impact on everyone she comes into contact while in cardiac rehab and this is why everyone who has gone through the program remembers working with Maggie!
