Treatment According to Venous Excess Ultrasound Score in Patients With Heart Failure

Patients will be randomized according to the sealed envelope method. While classical heart failure fluid management will be applied to patients in the conventional group, diuretic treatment will be given to the vexus group in a way that will reduce the vexus score, and the drugs and doses used in this treatment will be recorded. The development of acute renal failure in patients will be determined according to KDIGO criteria, but confirmation will be made with NGAL. Patients will be divided into two groups: those treated according to the VEXUS score and those treated simultaneously with VEXUS by a second experienced person (INTENSIVE CARE SPECIALIST) but treated conservatively. Patients' vital parameters, complete blood count, biochemistry, coagulation, arterial blood gas, procalcitonin, CRP, troponin, pro-BNP levels on Day 1 and Day 5 will be noted, and distensibility will be detected by USG on Days 1 and 5 among those with an IVC diameter \< 2 cm. or collapsibility index, and for those \> 2cm, VEXUS score will be calculated. In addition, EF, TAPSE, presence of pleural effusion or B-Line, renal resistive index, renal pulsatility index will be calculated.
