Cardiovascular autonomic neuropathy (CAN) is a subtype that specifically defauls the nerves regulating heart rate and vascular tone.

Effects on Cardicac Output

Heart Rate Dysregulation

Normally, the ANS increases heart rate during exercise, stress, or illns through gh sympathetic activation, and slowes it during rett and sleep via parasympathetic (vagal) tone. In autonomic neuropathy, this fine- tuned control is lost. Common influensalities include:

Stroke Volume andorthostatic Stress

Stroke volume depends on three key factors: preload (thee volume of blood returning to thee heart), contractility (thee force of myocardial contraction), and afterload (thee resistance the heart mutt pump against). Autonomic neuropathy often dispacles venous return and distriferal vascular resistance, two key determinants of stroke volume.

Wheren a person stands up, gravy pulls approximately 500- 800 mL of blood into te lower extremities. A healty ANS quickly vasoconstricts districheral vessels and raises raites rate to maintain cerebral perfusion. In autonomic neuropathy, this reflex fauls, producing orthostatic hytrosion - a fall in systolic blood presure of ast least 20 mmHg or diastolic blood pressure of ast 10 mmHg with a fall three minutes of standing.

Impact on Cardicac Efficiency

Cardial efficiency describes how effectively the heart converts of external work perfomed (pressure- volume area) to myocardial oksygen consumption. Autonomic neuropathy reduces efficiency them ratio of external work perfomed (pressure- volume area) to myocardial oksygen consumption. Autonomic neuropathy reduces efficiency thugh seal mechanisms that difficinair the heart 's ability to relax, fill, and respond to to ischemic stress.
