EFFECT IMBALANCE AQUEOUS BODY FLUIDS, AND RENAL DYSFUNCTION, CARDIOVASCULAR SURVIVAL IN PATIENTS AFTER AN ACUTE CORONARY SYNDROME, MYOCARDIAL REVASCULARIZATION

Abstract

Objective. Analysis imbalance aqueous body fluids on the prognosis of cardiovascular events in the late period after an acute coronary syndrome (ACS) and myocardial revascularization based on indicators of renal function.Materials and methods. The study included 120 patients with ACS, including unstable angina was diagnosed in 68 patients, 52 patients — acute myocardial infarction. All patients underwent myocardial revascularization. To register the presence of albuminuria in the range of 30-300 mg/l, and glomerular filtration rate (GFR). It makes calculations indicators aqueous body fluids — the total volume of water (TVW), the total fluid, intracellular fluid (IF), extracellular fluid. The endpoint of the study was the presence of cardiovascular complications within 6 months after ACS.Results. It is found that the presence and magnitude of albuminuria was significantly increase the risk of the end point of the study. In patients with GFR less than 60 mL/min/1,73m2 studied the risk is higher by 17.1%, compared with patients with a GFR above this limit. Analysis of the distribution of the water body fluids showed a significant increase in the average TVW and IF. Through statistical analysis of survival found an increased risk of cardiovascular complications in the late period after ACS in patients who have an increase IF on the stage of development of coronary catastrophe.Conclusion. The study demonstrated the predictive value to stratify cardiovascular disease risk, not only the presence of albuminuria, but its level and value of GFR less than 60 mL/min/1,73m2. Redistribution of aqueous body fluids in the form of increased IF is a marker of adverse cardiovascular events in the late period after ACS. These data indicate the need for a comprehensive and integrated analysis of existing pathogenetic changes occurring in ACS, as well as the status of the patients premorbid factor for improving risk stratification of cardiovascular complications in the long term after a cardiovascular accident.
