[Microalbuminuria and arterial hypertension]

Area of Science:

• Nephrology
• Cardiology
• Hypertension Research

Background:

• Uncontrolled hypertension significantly impacts kidney function, leading to potential renal dysfunction.
• Microalbuminuria, defined as urinary albumin excretion between 30-300 mg/24 h, indicates increased glomerular permeability due to elevated blood pressure.
• Persistent microalbuminuria in hypertensive patients can be reversible with normalized blood pressure levels.

Purpose of the Study:

• To highlight the impact of hypertension on kidney health.
• To define microalbuminuria and its clinical significance.
• To emphasize the importance of monitoring microalbuminuria in hypertensive individuals.

Main Methods:

• Assessing renal dysfunction through early detection of microalbuminuria.
• Correlating albuminuria levels with blood pressure measurements (inpatient and ambulatory).
• Investigating microalbuminuria as a risk factor for cardiovascular disease and nephroangiosclerosis.

Main Results:

• Microalbuminuria incidence increases with hypertension severity, exceeding 50% in severe cases.
• Albuminuria shows a positive correlation with blood pressure levels.
• Microalbuminuria is identified as a significant risk factor for cardiovascular disease and renal damage.

Conclusions:

• Microalbuminuria is a crucial early indicator of hypertensive kidney damage.
• Screening for microalbuminuria in hypertensive patients is recommended.
• Monitoring urine albumin effectively assesses antihypertensive treatment efficacy and aids in preventing renal damage.
