And Oxidative Stress

In the present study, we evaluated circulating pro-inflammatory mediators and markers of oxidative stress in patients with decompensated CHF (congestive heart failure) and assessed whether clinical recompensation by short-term inotropic therapy influences these parameters. Patients with worsening CHF (n=29, aged 61.9±2.7 years), NYHA (New York Heart Association) class III–IV, and left ventricular ejection fraction of 23.7±1.8% were studied. Controls comprised age-matched healthy volunteers (n=15; 54.1±3.2 years). Plasma levels of cytokines [IL (interleukin)-6 and IL-18], chemokines [MCP-1 (monocyte chemotactic protein-1)], adhesion molecules [sICAM (soluble intercellular adhesion molecule), sE-selectin (soluble E-selectin)], systemic markers of oxidation [TBARS (thiobarbituric acid-reactive substances), 8-isoprostaglandin F2α and nitrotyrosine] and hs-CRP (high-sensitivity C-reactive protein) were measured by ELISA and colorimetric assays at admission and 30 days following 72-h milrinone (n=15) or dobutamine (n=14) infusion. Plasma IL-6, IL-18, sICAM, E-selectin, hs-CRP and oxidative markers were significantly higher in patients on admission before inotropic treatment compared with controls (P<0.05). Short-term inotropic support improved clinical status as assessed by NYHA classification and by the 6-min walk test and significantly decreased plasma levels of IL-6, IL-18, sICAM, hs-CRP and markers of oxidation (P<0.05) at 30 days. The effects of milrinone and dobutamine were similar. In conclusion, our results demonstrate that patients with decompensated CHF have marked systemic inflammation and increased production of oxygen free radicals. Short-term inotropic support improves functional status and reduces indices of inflammation and oxidative stress in patients with decompensated CHF.

<strong>Background</strong>: It has been suggested that off-pump coronary<br />artery bypass grafting (CABG) surgery reduces myocardial<br />ischemia-reperfusion injury, postoperative systemic<br />inflammatory response, and oxidative stress. The aim of this<br />study was to measure serum malondialdehyde (MDA), highsensitivity<br />C-reactive protein (hs-CRP), M30, and M65 levels<br />and to investigate the relationship between M30 levels and<br />oxidative stress and inflammation in patients undergoing onand<br />off-pump CABG surgery.<br /><strong>Methods</strong>: Fifty patients were randomly assigned to onpump<br />or off-pump CABG surgery (25 patients off-pump and<br />25 on-pump CABG surgery), and blood samples were collected<br />prior to surgery, and 30 minutes, 60 minutes, 6 hours,<br />and 24 hours after CABG surgery.<br /><strong>Results</strong>: Compared to the on-pump group, serum MDA<br />levels at 30 minutes, 60 minutes, 6 hours, and 24 hours after<br />the CABG surgery were significantly lower in the off-pump<br />group (P = .001, P = .001, P = .001, and P = .001, respectively).<br />Serum M30 levels were found to be elevated in both groups,<br />returning to baseline at 24 hours. When compared to baseline,<br />the hs-CRP level reached its peak at 24 hours at 13.28 ±<br />5.32 mg/dL in the on-pump group, and 15.44 ± 4.02 mg/dL<br />in the off-pump group.<br /><strong>Conclusion</strong>: CABG surgery is associated with an increase<br />in inflammatory markers and serum M30 levels, indicating<br />epithelial/endothelial apoptosis in the early period.

Abstract Background Data about heart failure in Egypt is scarce. We aimed to describe the clinical characteristics and diagnostic and treatment options in patients with acute heart failure in the Delta region of Egypt and to explore the gap in the management in comparison to the international guidelines. Results DELTA-HF is a prospective observational cohort registry for all consecutive patients with acute heart failure (AHF) who were admitted to three tertiary care cardiac centers distributed in the Delta region of Egypt. All patients were recruited in the period from April 2017 to May 2018, during which, data were collected and short-term follow-up was done. A total of 220 patients (65.5% were males with a median age of 61.5 years and 50.9% had acute decompensation on top of chronic heart failure) was enrolled in our registry. The risk factors for heart failure included rheumatic valvular heart disease (10.9%), smoking (65.3%), hypertension (48.2%), diabetes mellitus (42.7%), and coronary artery disease (28.2%). Left ventricular ejection fraction (LVEF) was less than 40% in 62.6%. Etiologies of heart failure included ischemic heart disease (58.1%), valvular heart disease (16.3%), systemic hypertension (9.1%), and dilated non-ischemic cardiomyopathy (15.5%). Exacerbating factors included infections (28.1%), acute coronary syndromes (25.5%), non-compliance to HF medications (19.6%), and non-compliance to diet (23.2%) in acute decompensated heart failure (ADHF) patients. None of our patients had been offered heart failure device therapy and only 50% were put on beta-blockers upon discharge. In-hospital, 30 days and 90 days all-cause mortality were 18.2%, 20.7%, and 26% respectively. Conclusions There is a clear gap in the management of patients with acute heart failure in the Delta region of Egypt with confirmed under-utilization of heart failure device therapy and under-prescription of guideline-directed medical therapies particularly beta-blockers. The short-term mortality is high if compared with Western and other local registries. This could be attributed mainly to the low-resource health care system in this region and the lack of formal heart failure management programs.
