Welcome to Health Care Magic
Blood pressure is responsible for the diastolic dysfunction
. / Overt failure can result from hypertension
, but breathlessness in you may suggest more of anxiety
than pressure... You have not stated your personal habits, family history or co-morbidities, even age, gender...which could have an influence on the diagnosis and outcome...You have not even stated your actual pressure!
In population studies low calcium is associated with high pressure...Hyperparathyroidism
increases the calcium levels... The relations are not simple or direct / there is no cause for concern in your case. Wait for endocrinologist
Wishing speedy recovery
