Background:
Cardiovascular autonomic neuropathy (CAN) is a major complication of type 2 diabetes mellitus (T2DM), but the roles of arterial stiffness and right atrial (RA) function in CAN remain unclear.
Methods And Results:
In 120 patients with T2DM, we assessed short-term heart rate variability (CVR-R), cardio-ankle vascular index (CAVI), and two-dimensional speckle-tracking echocardiography (2DSTE). CAN was defined as CVR-R <2%. Multivariable analysis showed that higher CAVI and lower RA function composite scores were independently associated with CAN.
Conclusions:
Both increased arterial stiffness and impaired RA function characterized CAN, indicating a key cardiovascular interaction. Combined CAVI and RA strain assessment may aid early detection.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Assessment of the Cardiovascular System IV: Auscultation
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
Assessment of the Cardiovascular System III: Palpation
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
