Value of ambulatory blood pressure monitoring in type I (insulin-dependent) diabetic patients with incipient diabetic nephropathy.

Ambulatory blood pressure monitoring (ABPM) is currently proposed for measuring blood pressure in type I, insulin-dependent diabetic subjects with incipient diabetic nephropathy. However, the value of this method, in comparison with conventional ones in detecting blood pressure differences between normotensive type I, insulin-dependent diabetic subjects with or without microalbuminuria, is questionable. We obtained systolic, diastolic, and mean blood pressures (SBP/DBP/MBP) in 10 hospitalized normotensive type I, insulin-dependent diabetic subjects with microalbuminuria, and in 29 others without, using a mercury sphygmomanometer (method 1) and an automatic device (Dinamap; method 2) to obtain morning (9 to 11 AM) measurements, and ABPM (SpaceLabs 90207; method 3) to obtain daytime (7 AM to 10 PM) and nighttime (10 PM to 7 AM) measurements.

[Microalbuminuria and left ventricular hypertrophy in essential arterial hypertension. A study in non-diabetic patients].

To evaluate the relationship between urinary albumin excretion and left ventricular hypertrophy in essential hypertension, we studied, cross-sectionally, 64 subjects with essential hypertension and no diabetes. Urinary albumin excretion and Sokolow index correlated significantly (r = 0.483; P = 0.
