[Abstract]:Objective: To observe the efficacy and safety of levosimendan on the treatment of chronic systolic heart failure in patients with acute decompensated heart failure plus left Xi Mengdan on the basis of conventional medication.
Methods: a total of 74 patients with chronic systolic heart failure in five families of the second hospital of Hebei Medical University from September 2011 to December 2012 were randomly divided into 37 cases of levosimendan group (excluding 3 cases with cardiogenic shock or 34 ventricular tachycardia before drug intervention), the average age was 61.61 + 7.37 years old. Group 37 (36 cases of 1 patients with recurrent hyperthyroidism), the average age of 60.36 + 7.35 years. The standard of admission: 1, chronic systolic heart failure, and previously accepted standard heart failure treatment using angiotensin converting enzyme inhibitor (ACEI) or angiotensin II receptor antagonist (ARB), aldosterone receptor antagonist (MRA), beta blocker combination Treatment; 2, hospitalized for acute decompensation of chronic systolic heart failure; 3, cardiac function NYHA III - IV, echocardiography showed left ventricular ejection fraction (LVEF) < 40%. exclusion criteria: (1) atrial fibrillation, malignant arrhythmia before admission, and (2) cardiac shock and hypotension (90mmH) before admission. G, average pressure < 65mmHg), insufficient blood volume; (3) allergic constitution, with other anti heart failure drug allergy; (4) serious electrolyte disorder, severe liver, renal insufficiency, hemoglobin below 90g/L; (5) acute myocardial infarction in the last month, heart valve disease, pericardial disease, hypertrophic and restrictive cardiomyopathy, and autoimmune Disease, uncontrolled thyroid disease, symptomatic lung disease and use of hormone, theophylline treatment, combined with tumor; (6) the age of 80 years old; (7) patients or patients' families refused to participate in this study. The control group was given standard heart failure medication (ACEI or ARB, MRA, beta blocker), and diuretic drugs, digitalis In addition to the same treatment of the control group, the left Simendan group was given Levosimendan Injection (Levosimendan Injection, Yue Wen, Qilu pharmaceutical). First, the intravenous dose of 12 u g/kg was given to 0.05 mu g/kg/min as the initial dose of intravenous pump, and the dimension of the dose adjustment range was 0.05 u g/kg/min-0.2 mu g/kg/min. The contraction pressure was more than 90mmHg, the mean pressure was more than 65mmHg, the heart rate was less than 150 / sub, and the dosage was adjusted for 24 hours. The following indexes were observed: (1) the heart rate (secondary / score), respiratory frequency (mmHg), diastolic pressure (mmHg), 6 hours after medication, 12 hours, 24 hours, 48 hours, 48 hours, and systolic pressure (mmHg); (2) patients before medication, 7 days after medication. The value of B type natriuretic peptide (BNP); (3) left ventricular ejection fraction (LVEF%), left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVEDV), left ventricular end systolic volume (LVESV), per stroke volume (SV); (4) kidney function, liver function, electrolyte, hematocrit, red blood cell pressure, erythrocyte pressure, hematocrit and red blood of 7 days after drug use. (5) (5) before taking drugs, the heart function New York Heart Association (NYHA) was graded at 7 days after medication. The incidence of major adverse events (MACE) in two groups of patients was observed. MACE included hypotension, malignant arrhythmia, sudden death, and worsened heart failure. The statistical analysis of the observation data was carried out with SPSS13.0 software, and P < 0.05 was statistically significant difference. The difference is statistically significant.
