Key result
A complex pharmacological regimen successfully managed severe orthostatic hypotension and coexisting nocturnal supine hypertensive emergencies in a patient with advanced diabetic cardiac autonomic neuropathy.
Why the study?
Managing severe orthostatic hypotension in diabetic cardiac autonomic neuropathy is complicated by coexisting nocturnal supine hypertension, as treatments for these conditions often conflict.

Diabetic cardiac autonomic neuropathy (CAN) is caused by damage to the autonomic nerve fibers that innervate the heart and blood vessels, leading to abnormalities in heart rate control and vascular dynamics. CAN encompasses symptoms such as exercise intolerance, orthostatic hypotension, cardiac denervation syndrome, and nocturnal hypertension. Neurogenic orthostatic hypotension (nOH), resulting from severe diabetic CAN, can cause symptomatic orthostatic hypotension. The management of orthostatic hypotension primarily focuses on preventing severe symptoms, such as syncope and falls. It is equally important to address nocturnal supine hypertension, as it can exacerbate morning orthostatic hypotension. The management strategies for these conditions often complicate each other, highlighting the intricate and delicate nature of treating severe orthostatic hypotension associated with diabetic CAN. We present the case of a 55-year-old male with symptomatic orthostatic hypotension and coexisting nocturnal supine hypertension caused by severe, advanced diabetic CAN.

Nyan Lin Myint (2024) conducted a case report in Severe advanced diabetic cardiac autonomic neuropathy (n=1). Combined pharmacological therapy (droxidopa, fludrocortisone, pyridostigmine, atomoxetine, losartan, nifedipine) was evaluated on Symptom resolution and blood pressure control. A complex pharmacological regimen successfully managed severe orthostatic hypotension and coexisting nocturnal supine hypertensive emergencies in a patient with advanced diabetic cardiac autonomic neuropathy.
