Abstract
Aim To study clinical and laboratory associations of hepatic fibrosis indexes in patients with decompensated NYHA functional class II-IV chronic heart failure (CHF).Material and methods The study included 128 patients admitted to the cardiological or therapeutic department of the University Clinical Hospital #4 at the I. M. Sechenov First Moscow State Medical University (Sechenov University) with symptoms of CHF associated with ischemic heart disease (IHD) and/or arterial hypertension (AH). All patients had signs of liver disease (liver enlargement on physical examination ± diffuse changes in hepatic tissue according to ultrasound data). Mean age was 70.59±10.71 years. Along with general clinical examination, severity of hepatic fibrosis was evaluated by calculated indexes, FIB-4, APRI, MELD-XI, and BARD. All calculations were based on laboratory data obtained within the first two days of hospitalization for decompensated CHF, at the onset of active therapy with intravenous diuretics. Statistical analyses were performed with the R programming language (3.6.1).Results In patients with NYHA FC II-IV CHF, the FIB-4 index significantly increased with the increase in NYHA FC (р<0.05). Also, the high liver density by most fibrosis indexes correlated with the probability of LV EF decrease to <40 % (FIB-4: RR, 1.32 at 95 % CI from 0.53 to 3.28, р=0.079; MELD-XI: RR, 1.62 at 95 % CI from 1.19 to 2.20, р=0.004; BARD: median LV EF, 42.5 % vs. 56 %, р=0.019), and a tendency to heart rhythm disorders was observed (FIB-4: RR, 1.92 at 95 % CI from 0.75 to 4.90, р=0.218; BARD: RR, 1.09 at 95 % CI from 0.97 to 1.22, р=0.174; MELD-XI: RR, 1.34 at 95 % CI from 0.94 to 1.90, р=0.101). Increases in liver fibrosis indexes correlated with other multiorgan disorders in CHF patients evident as a decrease in platelet count (FIB-4: р<0.01; APRI: р=0.045) and a tendency to a decrease in hemoglobin (FIB-4: 127 g/l vs. 137 g/l, p=0.249; APRI: 127 g/l vs. 136 g/l, p=0.749). Patients with a high liver density more frequently had cardiorenal syndrome diagnosed by reduced glomerular filtration rate (GFR) estimated by CKD-EPI to less than 60 ml/min / 1.73 m2 (FIB-4: р<0.03; MELD-XI: p=0.0001; BARD: р=0.005). In comparing liver fibrosis indexes in subgroups of CHF patients with preserved and reduced left ventricular ejection fraction (LV EF), significant differences were found only for MELD-XI (12.08 vs. 9.32, р=0.001).Conclusions For all studied indexes, correlations were observed with LV EF, decreases in hemoglobin, and incidence of heart rhythm disorders. For the BARD, FIB-4, and MELD-XI indexes, high results of calculations correlated with the presence of other predictors for unfavorable prognosis and disease severity (LV EF, NYHA FC, presence of type 2 diabetes mellitus, chronic kidney disease, and lower GFR). Liver fibrosis indexes are a new and promising but understudied instrument for evaluation of prognosis in CHF patients, which requires further study to determine most appropriate prognostic formulas.
Highlights
Изучение клинико-лабораторных ассоциаций индексов печеночного фиброза у больных с декомпенсацией хронической сердечной недостаточностью (ХСН) II–IV функциональных классов (ФК) NYHA
Прогрессирование заболевания ведет к повреждению внутренних органов за счет их гипоперфузии и системного застоя, что позволяет рассматривать ХСН как полиорганную патологию [2]
Наряду с общеклиническим обследованием всем пациентам проводилась оценка выраженности печеночного фиброза по данным расчетных индексов: APRI, BARD, FIB-4, MELD-XI
Summary
Изучение клинико-лабораторных ассоциаций индексов печеночного фиброза у больных с декомпенсацией хронической сердечной недостаточностью (ХСН) II–IV функциональных классов (ФК) NYHA. Что неинвазивные тесты на фиброз имеют высокую ценность для прогнозирования вероятности летального исхода при различных внепеченочных заболеваниях [17, 19], позволяют рассматривать ИФП в качестве потенциальных предикторов неблагоприятных исходов у пациентов с ХСН, хотя их роль в оценке степени тяжести и прогноза у больных с заболеваниями сердца до настоящего времени изучена недостаточно. Всем пациентам проводилось стандартное обследование с проведением общего и биохимического анализов крови, общего анализа мочи, коагулограммы, электрокардиографического исследования, ультразвукового исследования органов брюшной полости и почек, рентгенографии
