What Causes Tiredness And Depression In A Cardiac Patient Despite Having Normal BP Values?
I would explain as follows:
Detailed Answer:
Hello!
Welcome and thank you for asking on HCM!
Regarding your concern, I would like to explain that your father has suffered 2 critical cardiac disorders (life-threatening conditions), and has fortunately survived, but with an important subsequent complication, which is heart failure.
A mild to moderate decrease of overall cardiac performance (left ventricular EF 45%) imposes an important exertion capacity reduction for a physically active individual such as your father is.
So, I would explain that a great proportion of his actual complains (extreme tiredness, and dyspnea) are thoroughly explained by his low cardiac output condition (because of his decreased LV pumping function and elevated LV end-diastolic pressure), despite his normal average BP values.
Other additional factors may have influenced as well, such as depression, which seems to be not rare in MI patients during the first year after heart attack occurrence (about 60% of patients).
A careful cardiac ultrasound could address the decreased value of cardiac output and cardiac index, increased LV end diastolic pressures (hence pulmonary capillary wedge pressure which may explain his shortness of breath), and consequently increased pulmonary artery systolic pressure (PASP).
A cardio-pulmonary exercise test would be helpful to determine your father's peak oxygen consumption, and hence his exercise capacity.
According to his clinical symptomatology, above echo parameters and exercise test, it would be possible to properly optimize his ongoing therapy.
From the other side, it is quite important for a heart attack patient to follow adequate physical rehabilitation program. There are several protocols, and almost all of them have shown beneficial effects regarding an optimal physical conditioning and improving exercise capacity.
Psychological issues should be addressed as well, as they may exacerbate the clinical symptomatology of HF, and may predict worse clinical outcome.
So, to conclude, I would recommend to discuss with his attending physician about the above mentioned issues, and to find the right modalities for optimizing his actual therapy, relieving possible anxiety and depressive issues, and yielding potential beneficial from a rehabilitation program.
Hope to have been helpful to you!
