Background: Mediterranean diet was evaluated on erectile performance and cardiovascular hemodynamics, in chronic heart failure patients. Methods: 150 male stable heart failure patients were enrolled in the study (62 ± 10 years, New York Heart Association (NYHA) classes I–II, ejection fraction ≤40%). A detailed echocardiographic evaluation including estimation of the global longitudinal strain of the left ventricle and the systolic tissue doppler velocity of the tricuspid annulus was performed. Erectile dysfunction severity was assessed by the Sexual Health Inventory for Men-5 (SHIM-5) score. Adherence to the Mediterranean diet was evaluated by the MedDietScore. Results: The SHIM-5 score was positively correlated with the MedDietScore (p = 0.006) and augmentation index (p = 0.031) and inversely correlated with age (p = 0.002). MedDietScore was negatively associated with intima-media-thickness (p < 0.001) and serum prolactin levels (p = 0.05). Multi-adjusted analysis revealed that the inverse relation of SHIM-5 and prolactin levels remained significant only among patients with low adherence to the Mediterranean diet (p = 0.012). Conclusion: Consumption of Mediterranean diet benefits cardiovascular hemodynamics, while suppressing serum prolactin levels. Such physiology may enhance erectile ability independently of the of the left ventricle ejection fraction.

Background: Statins are a well-established class of drugs in both preventing coronary events and treating cardiovascular atherosclerotic disease, however their use in heart failure is still in debate. </P><P> Objectives: To establish whether statins&#39; pleiotropic actions in endothelium, inflammation, remodeling of the heart and anti-arrhythmic potential may be in favorable of heart failure patients. </P><P> Methods: We proceed to literature search of English bibliography under the terms heart failure, statins, 3- hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors. </P><P> Results: Various experimental and clinical trials on the use of statins in the different subtypes of heart failure according to the ejection fraction of the left ventricle have been conducted to conclude whether statins should be part of their patients&#39; treatment. The evidence shows that the subgroup of patients with ischemic heart disease and those with preserved ejection fraction seems to have better results from the use of statins although randomized control trial in the total heart failure population did not show any benefit in mortality. </P><P> Conclusion: Statins may be beneficial to left ventricle systolic and diastolic performance of heart failure patients however their result in mortality cannot be established based on current evidence.

Background: Plasma amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 levels are positively associated with a higher risk of adverse clinical outcomes in acute heart failure. As a proxy of congestion, antigen carbohydrate 125 has also been proposed as a right-sided heart failure marker. Thus, we aimed to determine in this population the main factors – including echocardiographic right-sided heart failure parameters – associated with antigen carbohydrate 125 and amino-terminal pro-B-type natriuretic peptide. Methods and results: We prospectively included 2949 patients admitted with acute heart failure. Amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 were used as dependent variables in a multivariable linear regression analysis. The mean age of the sample was 73.9±11.1 years; 48.9% were female, 35.8% showed ischaemic aetiology, and 51.6% exhibited heart failure with preserved ejection fraction. The median (interquartile range) for amino-terminal pro-B-type natriuretic peptide and antigen carbohydrate 125 were 4840 (2111–9204) pg/ml and 58 (26–129) U/ml, respectively. In a multivariable setting, and ranked in order of importance (R2), estimated glomerular filtration rate (43.7%), left ventricle ejection fraction (15.1%), age (12.4%) and high-sensitivity troponin T (10.9%) emerged as the most important factors associated with amino-terminal pro-B-type natriuretic peptide. The five main factors associated with antigen carbohydrate 125 were, in order of importance: the presence of pleural effusion (36.8%), tricuspid regurgitation severity (25.1%), age (11.9%), amino-terminal pro-B-type natriuretic peptide (6.5%) and peripheral oedema (4.3%). Conclusion: In patients with acute heart failure the main factors associated with amino-terminal pro-B-type natriuretic peptide were renal dysfunction, left ventricle ejection fraction and age. For antigen carbohydrate 125, clinical parameters of congestion and the severity of tricuspid regurgitation were the most important predictors. These results endorse the value of antigen carbohydrate 125 as a useful marker of right-sided heart failure.

Heart failure represents a growing health problem, with increasing morbidity and mortality globally. According to the mechanisms involved in the pathogenesis of heart failure, many biomarkers have been proposed for the timely diagnosis and prognostication of patients with heart failure, but other than natriuretic peptides, none of them has gained enough clinical significance. Renalase, a new protein derived from kidneys was demonstrated to metabolize catecholamines and to have a cardioprotective role. The aim of the study was to determine whether renalase and brain natriuretic peptide (BNP) concentration could be used to differentiate heart failure patients stratified to the category of the ejection fraction and whether plasma renalase could be used as a biomarker for left ventricle hypertrophy in all subgroups of heart failure patients. We included patients diagnosed with heart failure and stratified them to the three subgroups according to the ejection fraction. Regarding echocardiographic parameters, HFmrEF had an intermediate profile in between HFrEF and HFpEF, with statistical significance in most evaluated parameters. BNP concentration was significantly different in all three subgroups (p<0.001), and renalase was statistically higher in HFrEF (p=0.007) compared to the HFmrEF and HFpEF, where its results were similar, without statistical significance. Renalase plasma concentration was demonstrated to be highly and positively associated with left ventricle mass index in HFrEF (p=0.029), as well as increased plasma concentration of BNP (p=0.006). In the HFmrEF group of patients, body mass index was positively associated with LVMI (p=0.05), while in the patients with HFpEF, diabetes mellitus was demonstrated to have a positive association with LVMI (p=0.043). These findings suggest that renalase concentration may be measured in order to differentiate patients with reduced ejection fraction. Plasma renalase concentrations positively correlated with left ventricle hypertrophy in patients with reduced ejection fraction, being strongly associated with increased left ventricular mass index.

Įvadas / tikslasProfilaktinis milrinono skyrimas gerina širdies veiklą, sumažina pooperacinės intraaortinės balioninės kontrapulsacijos (IABK) poreikį. Keletas atliktų tyrimų patvirtino priešoperacinės IABK naudą išgyvenamumui. Pagrindinis mūsų tyrimo tikslas buvo palyginti IABK arba milrinono skyrimo didelės rizikos pacientams, kuriems atliekamos miokardo revaskuliarizacijos operacijos, įtaką hemodinamikos rodikliams ir pooperaciniam sergamumui.Ligoniai ir metodaiTai retrospektyvioji 29-ių didelės rizikos pacientų, kuriems atliktos miokardo revaskuliarizacijos operacijos per vienerius metus tame pačiame centre, duomenų analizė. Pacientai, kurie operuoti be dirbtinės kraujo apytakos, į tyrimą neįtraukti. Milrinonu gydyta 14 pacientų, intraaortine balionine kontrapulsacija – 15 pacientų. Abiejų grupių pacientų hemodinamika stebėta įkišus Swan-Ganz kateterį. Buvo vertinami priešoperaciniai rizikos veiksniai, operaciniai duomenys, pooperacinis sergamumas ir hemodinamikos rodikliai.RezultataiPalyginus grupes prieš operaciją, jos statistiškai patikimai nesiskyrė pagal amžių (64 ± 10 vs 66 ± 9), lyčių pasiskirstymą (vyrai/moterys, 12/3 vs 11/3) ar operacinę riziką, vertinamą Euroscore balais (5,5 ± 3,8 vs 4,9 ± 2, p=0,69). Kairiojo skilvelio išvaromoji frakcija buvo mažesnė pacientų, gydytų taikant intraaortinę kontrapulsaciją (35 ± 5 proc. vs 39 ± 5 proc., p=0,03). Palygintas operacinis ir pooperacinis minutinis širdies tūris. Milrinonu gydytiems pacientams reikėjo didesnių dozių norepinefrino pirmosiomis pooperacinėmis valandomis (0 val. 0,07 ± 0,06 vs 0,01 ± 0,02 μg/kg/min., p=0,01, ir po 4 val. 0,08 ± 0,05 vs 0,03 ± 0,02 μg/kg/min., p=0,01). Pooperacinės komplikacijos tarp grupių statistiškai patikimai nesiskyrė: širdies nepakankamumas (29 proc. vs 33 proc.), insultas (7 proc. vs 7 proc.), inkstų funkcijos sutrikimas (7 proc. vs 13 proc.), delyras (22 proc. vs 13 proc.). Gydymo trukmė Reanimacijos ir intensyviosios terapijos skyriuje buvo panaši (6 ± 7 vs 4 ± 2 dienos). Keturiems (29 proc.) milrinono grupės pacientams prireikė IABK širdies nepakankamumui gydyti pooperaciniu laikotarpiu.IšvadosProfilaktinė IABK dažniau skirta pacientams, kurių kairiojo skilvelio išvaromoji frakcija mažesnė. Priešoperacinis milrinono ar IABK skyrimas turėjo panašią įtaką pacientų širdies veiklos gerinimui. Abiejų grupių ligonių pooperacinis sergamumas nesiskyrė. Tačiau 29 proc. milrinonu gydytų pacientų prireikė intraaortinės kontrapulsacijos pooperaciniu laikotarpiu.Reikšminiai žodžiai: miokardo revaskuliarizavimas, intraaortinė balioninė kontrapulsacija, milrinonas Preemptive milrinone versus intraaortic balloon pump in high risk coronary artery bypass grafting surgeryBackground / objectivePre-emptive milrinone infusion improves cardiac performance. The decrease of postoperative IABP insertions was possibly related with the increased use of phosphodiesterase inhibitors. The survival benefit of preoperative treatment with IABP was shown in several studies. The aim of our study was to compare the impact of the prophylactic administration of milrinone or IABP on haemodynamics and postoperative morbidity in high-risk patients undergoing on-pump CABG surgery.Patients and methodsThe retrospective analysis involved 29 elective high-risk CABG patients operated on during one year period in a single institution. Patients operated off-pump were excluded from the study. Pretreatment with milrinone was performed in 14 patients while prophylactic IABP was used in 15 cases. A Swan–Ganz catheter was inserted for haemodynamic monitoring in all cases. Preoperative risk factors, intraoperative variables, postoperative morbidity and haemodynamics were compared between the groups.ResultsPreoperative patient profile was comparable between the groups. There were no difference in patient age (64 ± 10 vs 66 ± 9), male / female ratio (12/3 vs 11/3) or preoperative Euroscore (5.5 ± 3.8 vs 4.9 ± 2, p = 0.69). However, the left ventricle ejection fraction was lower in the IABP-treated patient group (35 ± 5 perc. vs 39 ± 5 perc., p = 0.03). Inrtaoperative and postoperative cardiac output was comparable between the groups. Milrinone-treated patients had higher requirement of norepinephrine on ICU arrival (0.07 ± 0.06 vs 0.01 ± 0.02 μg/kg/min, p = 0.01) and 4 hours following surgery (0.08 ± 0.05 vs 0.03 ± 0.02 μg/kg/min, p = 0.01). No differences were found in the rate of heart failure (29 perc. vs 33 perc.), stroke (7 perc. vs 7 perc.), renal failure (7 perc. vs 13 perc.), postoperative delyrium (22 perc. vs 13 perc.) or ICU stay duration ( 6 ± 7 vs 4 ± 2 days). Four of 14 (29 perc.) patients needed IABP insertion in the postoperative period due to heart failure progression.ConclusionsProphylactic treatment with IABP was used in patients with a lower left ventricle ejection fraction. Pre-emptive milrinone infusion and IABP insertion before surgery had a similar impact on the improvement of cardiac performance during on-pump CABG surgery. No difference in postoperative morbidity was found between the groups of patients. However, almost 29 perc. of patients treated with milrinone needed IABP insertion in the postoperative period.Key words: coronary revascularization, intraaortic balloon counterpulsation, milrinone

Background: Individuals born preterm present left ventricle changes and increased risk of cardiac diseases and heart failure. The pathophysiology of heart disease after preterm birth is incompletely understood. Mitochondria dysfunction is a hallmark of cardiomyopathy resulting in heart failure. We hypothesized that neonatal hyperoxia in rats, a recognized model simulating preterm birth conditions and resulting in oxygen-induced cardiomyopathy, induce left ventricle mitochondrial changes in juvenile rats. We also hypothesized that humanin, a mitochondrial-derived peptide, would be reduced in young adults born preterm. Methods: Sprague-Dawley pups were exposed to room air (controls) or 80% O 2 at postnatal days 3 to 10 (oxygen-induced cardiomyopathy). We studied left ventricle mitochondrial changes in 4 weeks old males. In a cohort of young adults born preterm (n=55) and age-matched term (n=54), we compared circulating levels of humanin. Results: Compared with controls, oxygen-exposed rats showed smaller left ventricle mitochondria with disrupted integrity on electron microscopy, decreased oxidative phosphorylation, increased glycolysis markers, and reduced mitochondrial biogenesis and abundance. In oxygen-exposed rats, we observed lipid deposits, increased superoxide production (isolated cardiomyocytes), and reduced Nrf2 gene expression. In the cohort, left ventricle ejection fraction and peak global longitudinal strain were similar between groups however humanin levels were lower in preterm and associated with left ventricle ejection fraction and peak global longitudinal strain. Conclusions: In conclusion, neonatal hyperoxia impaired left ventricle mitochondrial structure and function in juvenile animals. Serum humanin level was reduced in preterm adults. This study suggests that preterm birth–related conditions entail left ventricle mitochondrial alterations that may underlie cardiac changes perpetuated into adulthood.
