[Albuminuria and cardiovascular risk: basal results of the KORAL-CARDIO study].
OBJECTIVE
Albuminuria is a marker of higher cardiovascular and renal risk in hypertension; it also indicates the need of a tighter control of blood pressure with drugs blocking the renin-angiotensin system. The objective of the KORAL-CARDIO study was to assess the clinical picture and management of patients with hypertension and cardiac disease and albuminuria not previously treated with angiotensin inhibitors.


METHODS
A total of 2711 hypertensive patients (44% female) with ischemic or hypertensive cardiopathy or atrial fibrillation and with a positive screening test for albuminuria was included. Type 2 diabetes was also present in 42%.


RESULTS
Macroalbuminuria was present in 7.2% of non diabetic and 12.7% of diabetic patients, respectively. Associated complications were: 25% and 35% body mass index over 30 kg/m2; 22% and 39% ischemic heart disease; 4% and 8% stroke; 19% and 22% atrial fibrillation; 42% and 53% high cholesterol levels; 8% and 8% grade 3 hypertension, for non-diabetics and diabetics respectively. Antihypertensive monotherapy was used in 66% of non-diabetics and in 63% of diabetics; only 7% of patients in both groups were treated with triple antihypertensive therapy.


CONCLUSIONS
Cardiovascular complications are very frequently associated to albuminuria in patients with hypertension and heart disease not previously treated with angiotensin inhibitors. Blood pressure control was clearly inadequate in this group.
