A.L.Greco, S.F.Greco. ~edical Department B.Ramazzini ~ospital, Carpi (~odena) - Italy From 1 0 90 to 1993 at the Antidiabetia Center of our Medical Department 867 ~ta ~et1.,patients have been osserved; 1?) were males (18.8~) with a mean age of 61 years and 444 were females (SI.2d ) with a mean age of 6, years. Diabetes Type I was observed in l ' patients (,.2~), diabetes ~pe II in 8?2 patients (04.8). 624 patients were obese (72~). ffypertensian was diagnosed .in 10, cases (16.7 d ). Hypertension preceeded diabetes in 116 patients (R3%) while diabetes precee~e~ hyp0rtension in 6° cases (171). HYpertension was ~ignose~ in 6~ of females an~ in 4~ of males. Diabetics with alteratio n of lipid metabolism were 100 (11.6~'. S7/100 (l~) had hypercolesterolemia type II of Fredrtckson,II7 (39%) had hypertrigliceri~emia (type IV) and I?6 had d;tslipidemia type lIB" (421). In this group of 300 patients hypertension was present in 1,1 cases ('I~). In 40, patients with ~iabetes and hypertension, obesity was present in l?I cases (7a.2~); Conclusion:thc great fre~uency of the association of ~iabetps,dyslipi~emia an~ hypertension c~n probably lea~ to a nega~ tive reciprocal interacti0n.

GI9 OSCILLATORY INDEX OF ELECTRORETINOGRAM (01) IS CORRELATED WITH LEFT VENTRICULAR THICKNESS IN YOUNG UNTREATED HYPERTENSIVE PATIENTS. E. Bocin, A. Coscnzl, A. Sacerdote, R. Molino, ·N.Solimano,

The authors have previously demonstrated that the 01 is early reduced in borderline hypertensive patients without retinal changes observed Ihrough fundoschopy. The aim of Ihis study has been 10 investigate whelher these changes are related with left ventricular hypertrophy. a recognised fcature of targel organ mvolvement in hypertension. Nme untreated borderline hypertensive patients (age 2UI yrs) were admilled to this sludy All subjects had at least three omce blood pressure measurement within one month, to confirm Ihe diagnOSIs of hypertenSIon. Silting blood pressure was measured for statlsllcal evaluallon with a mercury sphygmomanomeler after IOmln res\. Oseillalory potentials of electrorelinogram were recorded afier IS min rellnal mesopic adaptation. 01 was calculated by adding Ihe amplitudes of the wavwlels 01. 02 and 03 within the b wave of electroretmogram The Ihickness of the septum (LVS) and Ihe posterior wall (LVPW) of len ventricle was measured by means of M-mode and B-mode echoeardiography. Results are reponed as mean ± standard deviation: SBP(mmHg) DBP(mmHg) LVS (mm) LVPW(mm) OI(IlV) 133±6
An inverse relallon of 01 has been demonslrated with the thickness of both LVS (R= .0 705. p=O.03) and LVPW (R=oO 777. p. 0.01) by means of linear regression tes\. These results demonstrate that 01 are not only early decreased in young hypenenslVe pallents but are also strenghtly correlated with left venlrlcular Ihickness. a recogntsed marker of cardiac mvolvement in hypertension. playing a great prognostic role.
