This experiment was designed to determine whether Tribuli saponins (TS) relieve left ventricular remodeling (VR) after myocardial infarction (MI) in a murine hyperlipemia (HL) model. MI and HL models were induced and high and low doses of TS and simvastatin were administrated to the rats. Four weeks later, echocardiographic observation was performed and the left and right ventricular weight index (LVWI, RVWI) was calculated. Echocardiographic results showed that both high dose of TS and simvastatin had a beneficial effect on increasing fractional shortening (FS) and ejection fraction (EF), reducing left ventricular end diastolic volume (LVEDV), systolic volume (LVESV), left ventricular dimension end diastole (LVDd) and systole (LVDs), and decreasing LVWI, as compared to those in the HL-MI model group ( p < 0.05, 0.01). Both medicines had little impact on thickness of the anterior and posterior wall. No significant difference was observed between each treatment group ( p > 0.05). In conclusion, TS not only lowered serum lipidemia, but also relieved left ventricular remodeling, and improved cardiac function in the early stage after MI.

Background. Left ventricular remodeling is a complex pathologic process of progressive left ventricular dilatation, leading to dysfunction and heart failure in patients after myocardial infarction. Objective. To evaluate biochemical markers, reflecting cardiac remodeling process after first myocardial infarction and compare those markers with clinical characteristics of left ventricular remodeling. Material and methods. Brain natriuretic peptide, troponin I, creatine kinase, creatine kinase MB mass, lactate dehydrogenase levels were measured in 30 patients with acute myocardial infarction on days 1, 2, 3–7 . Brain natriuretic peptide was measured at 3 months, 6 months, and 2 years after myocardial infarction. Echocardiographic parameters of left ventricular remodeling were determined in acute phase (day 1–3), at 3 months, 6 months, and 2 years after MI. Results. In acute phase, brain natriuretic peptide level progressively increased according to worsening of left ventricular geometry: in normal left ventricle geometry group, brain natriuretic peptide level was 84.1 (58.7–121) pg/mL, in concentric remodeling group – 125 (69.2–165) pg/mL, in concentric hypertrophy group – 128 (74–368) pg/mL, and in eccentric hypertrophy group – 470 (459–494) pg/mL, P=0.02. Patients who had increased left ventricular end diastolic diameter index during 2-year period had higher brain natriuretic peptide level in the acute phase (584 (249–865) pg/mL vs. 120 (67–202) pg/mL, P=0.04) and also higher peak lactate dehydrogenase and troponin I levels. Conclusions. Brain natriuretic peptide level in acute phase of myocardial infarction is strongly associated with the markers of myocardial injury and related to left ventricular geometry changes and remodeling. Brain natriuretic peptide together with troponin I levels in acute phase of myocardial infarction might be useful in predicting subsequent cardiac function.

Abstract Heart failure is a clinical syndrome that appears as a consequence of a structural disease, and the most common cause of left ventricular systolic dysfunction results from myocardial ischemia. Cardiac remodeling and neuroendocrine activation are the major compensatory mechanisms in heart failure. The main objective of the study is to identify the association between serum biomarkers illustrating the extent of myocardial necrosis (highly sensitive troponin as-says), left ventricular dysfunction (NT-proBNP), and systemic inflammatory response (illustrated via serum levels of hsCRP and interleukins) during the acute phase of a myocardial infarction, and the left ventricular remodeling process at 6 months following the acute event, quantified via speckle tracking echocardiography. The study will include 400 patients diagnosed with acute myocardial infarction without signs and symptoms of heart failure at the time of enrollment that will undergo a complex clinical examination and speckle tracking echocardiography. Serum samples from the peripheral blood will be collected in order to determine the inflammatory serum biomarkers. After 6 months, patients will be divided into 2 groups according to the development of ventricular remodeling, quantified by speckle tracking echocardiography: group 1 will consist of patients with a remodeling index lower than 15%, and group 2 will consist of patients with a remodeling index higher than 15%. All clinical and imaging data obtained at the baseline will be compared between these two groups in order to determine the features associated with a higher risk of deleterious ventricular remodeling and heart failure.
