Abstract

Background: A number of cytokines and adipokines secreted by adipose tissue may influence vessel wall directly. Adiponectin exhibits anti-inflammatory and atheroprotective actions. Resistin is expressed at higher levels in inflammatory cells. Resistin directly activates the endothelium through upreglation of adhesion molecules, induces production of TNF-α by macrophages, effects that are antagonized by adiponectin. Leptin has multiple effects on cells of artery walls, many similar to those of resistin. The prognostic role of adipokines in atherosclerosis is not well established. Methods: We compared the baseline plasma levels of adiponectin, resistin, leptin and TNF-α (ELISA assays) in 59 patients with coronary artery disease (CAD) and 32 patients with peripheral artery disease (PAD). Also, we investigated the impact of baseline plasma levels of adiponectin, resistin, leptin and TNF-α on the incidence of the new ischemic cardiovascular events. Results: In patients with CAD, as compared with PAD, baseline plasma levels of leptin were significantly increased (2882.02 ± 368.57pg/ml vs 1025.56 ± 232.28 pg/ml; p<0.001), plasma levels of resistin were significantly decreased (13.15 ± 0.83ng/ml vs 17.76 ± 2.13 ng/ml; p = 0.02) and no differences in plasma levels of adiponectin and TNF-α were found. A significant correlation between BMI and plasma levels was found only for leptin, irrespective of group. 45 patients (49.5%) were re-hospitalized in a 2 years period of follow-up. In a backward stepwise multivariable Cox regression analysis only resistin ≥ 15 ng/ ml, HR =1.8829, 95% CI 1.0490- 3.3797, p = 0.034 and diastolic blood pressure ≥ 85 mmHg, HR =2.0927, 95%CI 1.0782- 4.0616, p=0.0299 were associated with new cardiovascular events. Conclussion: In patients with clinical atherosclerosis plasma levels of resistin predict new ischemc events.

Abstract

Background: Apelin is a potent endogenous inotropic peptide with a major role in counteracting the aldosterone and angiotensin II and their negative effects on the cardiovascular system. The exact role of apelin in the patho-physiology of this disease is not well understood. We aimed to investigate the possible associations of apelin-13 with clinical and paraclinical characteristics in HF patients as well as studying its dynamics during the course of the heart failure.

Method: We performed a prospective observational cohort single-center study. We compared the baseline serum levels of apelin-13 and NT-proBNP level in 53 heart failure patients (acute heart failure, chronic compensated heart failure and chronic decompensated heart failure). We divided the patients according to the apelin-13 level: above and below the median, and we analyzed the relationship between serum apelin-13 and the clinical, echocardiographic, electrocardiographic and biological parameters. Twenty patients were followed-up (after an average time interval of 9 months), investigating the same parameters.

Results: The median of apelin-13 was 495pg/mL (IQR 276-845pg/mL). We found strong, negative correlation between the serum levels of apelin-13 and NT-proBNP (Spearman rho= −0.83, p<0.001). For the reassessed patients the median apelin level was significantly higher at follow-up (460 pg/mL, IQR 342-871 pg/mL) as compared with the baseline level (395 pg/mL, IQR 270-603 pg/mL), p=0.019, and maintained the negative correlation with NT-proBNP level (Spearman’s rho −0.7, p<0.001. The Low Apelin-13 group have higher NT-proBNP levels and also contains all the patients in NYHA IV class heart failure, 71% of the acute HF patients, and 7 of 8 patients who died before follow-up.

Conclusion: Apelin-13 was negatively correlated with NT-proBNP. The Low Apelin-13 group contained the majority of the patients with a negative outcome (death before follow-up), most of the patients who presented with acute HF and all the patients in NYHA IV class.
