Creatine is a key player in heart contraction and energy metabolism. Creatine supplementation (throughout the paper, only supplementation with creatine monohydrate will be reviewed, as this is by far the most used and best-known way of supplementing creatine) increases creatine content even in the normal heart, and it is generally safe. In heart failure, creatine and phosphocreatine decrease because of decreased expression of the creatine transporter, and because phosphocreatine degrades to prevent adenosine triphosphate (ATP) exhaustion. This causes decreased contractility reserve of the myocardium and correlates with left ventricular ejection fraction, and it is a predictor of mortality. Thus, there is a strong rationale to supplement with creatine the failing heart. Pending additional trials, creatine supplementation in heart failure may be useful given data showing its effectiveness (1) against specific parameters of heart failure, and (2) against the decrease in muscle strength and endurance of heart failure patients. In heart ischemia, the majority of trials used phosphocreatine, whose mechanism of action is mostly unrelated to changes in the ergogenic creatine-phosphocreatine system. Nevertheless, preliminary data with creatine supplementation are encouraging, and warrant additional studies. Prevention of cardiac toxicity of the chemotherapy compounds anthracyclines is a novel field where creatine supplementation may also be useful. Creatine effectiveness in this case may be because anthracyclines reduce expression of the creatine transporter, and because of the pleiotropic antioxidant properties of creatine. Moreover, creatine may also reduce concomitant muscle damage by anthracyclines.

The discussion continues about the role of systemic inflammation in the pathogenesis of cardiovascular diseases of ischemic etiology. This article reviews the information on the role of C-reactive protein in patients with atherosclerosis and heart failure in risk stratification for adverse cardiovascular events, including assessment of factors affecting the basal level of highly sensitive C-reactive protein. Research data (MRFIT, MONICA) have demonstrated a relationship between an increased level of C-reactive protein and the development of coronary heart disease. An increase in the serum level of highly sensitive C-reactive protein is observed in arterial hypertension, dyslipidemia, type 2 diabetes mellitus and insulin resistance, which indicates the involvement of systemic inflammation in these disorders. Currently, the assessment of highly sensitive C-reactive protein is used to determine the risk of developing myocardial infarction and stroke. It has been proven that heart failure patients have a high level of highly sensitive C-reactive protein compared with patients without heart failure. The level of C-reactive protein is referred to as modifiable risk factors for cardiovascular diseases of ischemic origin, since lifestyle changes or taking drugs such as statins, non-steroidal anti-inflammatory drugs, glucocorticoids, etc. reduce the level of highly sensitive C-reactive protein. In patients with heart failure with different left ventricular ejection fraction values, it was found that the regression of the inflammatory response is accompanied by an improvement in prognosis, which confirms the hypothesis of inflammation as a response to stress, which has negative consequences for the cardiovascular system.

Chronic heart failure is still a major challenge for healthcare. Currently, cardiac resynchronisation therapy (CRT) has been incorporated into the updated guideline for patients with heart failure, left ventricular ejection fraction ≤35 % and prolonged QRS duration. With 20 years of development, the concept of ‘from bench to bedside’ has been illustrated in the field of CRT. Given the fact that the indications of CRT keep evolving, the role of CRT is not limited to the curative method for heart failure. We therefore summarise with the perspective of 5P medicine – preventive, personalised, predictive, participatory, promotive, to review the benefit of CRT in the prevention of heart failure in those with conventional pacemaker indications, the individualised assessment of patient’s selection, the predictor of responders of CRT, and the obstacles hindering the more application of CRT and the future development of this device therapy.

The previous studies have shown that plasma chitotriosidase (CHIT) levels increase in many diseases with inflammation. However, there are no reported studies investigating the relationship between CHIT and chronic heart failure (CHF) which is an inflammatory process. Therefore, we aimed to investigate the role of CHIT in diagnosis and severity of CHF in this study. 36 patients (50% male, mean age 63.17±10.18 years) with left ventricular ejection fraction <40% and 27 controls (44% male, mean age 61.33±8.73 years) were included in this study. Patients with CHF were divided into two groups as ischemic heart failure (IHF) and non-ischemic heart failure (NIHF) according to the underlying etiology. Plasma CHIT and N-terminal pro brain natriuretic peptide (NT-proBNP) levels were measured by ELISA method. Plasma CHIT and NT-proBNP levels were higher in patients with CHF than in controls (CHIT 931.25±461.39 ng/mL, 232.79±61.28 ng/mL, p<0.001; NT-proBNP, 595.31±428.11 pg/mL vs 78.13±30.47 pg/L; p<0.001). Also, the levels of these parameters increased in IHF compared with NIHF (CHIT, 1139.28±495.22 ng/mL, 671.22±237.21 ng/mL, p=0.002; NT-proBNP, 792.87±461.26 pg/mL vs 348.36±202.61 pg/mL, p=0.001) and there was a strong correlation between NT-proBNP and CHIT (r=0.969, p<0.001). According to this study findings, plasma CHIT level increases in CHF and its increased levels are correlated with NT-proBNP which is used diagnosis and prognosis of HF.

Abstract OBJECTIVES to evaluate the prognosis role of late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (cMRI) in patients with non-ischemic dilated cardiomyopathy (NIDM). BACKGROUND Risk stratification in NIDM needs to be improved. METHODS We included 210 patients with NIDM and cMRI from 2005 to 2018 in our study population. Outcomes were retrospectively assessed by medical records. The pattern of LGE was classified as mid-wall, sub-epicardial, or both patterns. Primary endpoint was sudden cardiac death (SCD) or aborted SCD. Secondary endpoints were global mortality and a composite endpoint of cardiovascular mortality and heart failure hospitalization. Demographic and clinical parameters were also evaluated. Patients with LGE (LGE+) were more likely to be male (80,6% vs 66,7%, p= 0,03). No significant differences were observed between LGE+ and LGE- patients in comorbidities, NYHA class, left ventricular ejection fraction (LVEF), or neurohormonal treatment. RESULTS Of 210 patients (71,4% men, median age 59,8 years) with a median follow up of 5,6 years (3,24-8,15), 72 patients (34,3%) had non ischemic LGE (LGE+) on cMRI. Mean left ventricular ejection fraction (LVEF) was 34%. SCD or aborted SCD occurred in 11 patients (5,2%): 6 patients (9,5%) with LGE+ vs 5 patients (4,07 %) of LGE- (p = 0,19). Patients with LGE+ had a higher risk for the composite endpoint (cardiovascular mortality and heart failure hospitalization): OR 2,45, confidence interval (CI): 1,16-5,17, (p = 0,02). LGE presence was not associated with global mortality. The subepicardial pattern of LGE was associated with SCD or aborted SCD. 3 out of 11 patients (27%), with subepicardial pattern of LGE suffered from SCD or aborted SCD (p= 0,01). CONCLUSIONS In our cohort of 210 patients with NIDM, LGE was not significatively associated with SCD or aborted SCD, probably because of a low event rate (5,2%) in a relatively small and well treated population, despite a long follow-up (5,6 years). On the other hand, LGE presence was associated with a higher risk for the composite endpoint of cardiovascular mortality and heart failure hospitalization. Finally, the subepicardial pattern of LGE identified a group of patients at high risk of SCD and aborted SCD.

The role of catestatin (CST) in acutely decompensated heart failure (ADHF) and myocardial infarction (MI) is poorly elucidated. Due to the implicated role of CST in the regulation of neurohumoral activity, the goals of the study were to determine CST serum levels among ninety consecutively enrolled ADHF patients, with respect to the MI history and left ventricular ejection fraction (LVEF) and to examine its association with clinical, echocardiographic, and laboratory parameters. CST levels were higher among ADHF patients with MI history, compared to those without (8.94 ± 6.39 vs. 4.90 ± 2.74 ng/mL, p = 0.001). CST serum levels did not differ among patients with reduced, midrange, and preserved LVEF (7.74 ± 5.64 vs. 5.75 ± 4.19 vs. 5.35 ± 2.77 ng/mL, p = 0.143, respectively). In the multivariable linear regression analysis, CST independently correlated with the NYHA class (β = 0.491, p < 0.001), waist-to-hip ratio (WHR) (β = −0.237, p = 0.026), HbA1c (β = −0.235, p = 0.027), LDL (β = −0.231, p = 0.029), non-HDL cholesterol (β = −0.237, p = 0.026), hs-cTnI (β = −0.221, p = 0.030), and the admission and resting heart rate (β = −0.201, p = 0.036 and β = −0.242, p = 0.030), and was in positive association with most echocardiographic parameters. In conclusion, CST levels were increased in ADHF patients with MI and were overall associated with a favorable cardiometabolic profile but at the same time reflected advanced symptomatic burden (CATSTAT-HF ClinicalTrials.gov number, NCT03389386).
