Conclusions Further studies are required in order to establish the complicated association between SARS-CoV-2 infection and its effects on the cardiovascular system. Our knowledge regarding diagnostic approaches, therapeutic management and preventive measures is constantly enriched throughout an abundance of ongoing research in the respective fields.SARS-CoV-2 is spreading rapidly all over the world. The case fatality rate seems higher in cardiovascular disease and hypertension. GSK2879552 purchase Other comorbidities do not seem to confer the same risk, therefore the understanding of the relationship between infection and cardiovascular system could be a crucial point for the fight against the virus. A great interest is currently directed towards the angiotensin 2 converting enzyme (ACE 2) which is the SARS-CoV-2 receptor and creates important connections between the virus replication pathway, the cardiovascular system and blood pressure. All cardiovascular conditions share an imbalance of the renin angiotensin system (RAAS) in which ACE 2 plays a central role. In the last few days, much confusion has appeared about the management of therapy with angiotensin converting enzyme inhibitors (ACE-i) and angiotensin receptor blockers (ARBs) in infected patients and in those at risk of critical illness in case of infection. In this article we will try to reorder the major opinions currently emerging on this topic.Global longitudinal strain (GLS) has emerged as a valuable diagnostic and prognostic tool for evaluating left ventricular (LV) function. GLS has been shown to be a more sensitive marker of LV dysfunction than LV ejection fraction alone and have prognostic impact in non-surgical cardiac populations. GLS, is validated, reproducible, and easily obtained from 2-dimensional speckle- tracking echocardiography. While there is strong evidence for using GLS in clinical decision- making in non-surgical populations, there is less summarized evidence on using GLS in the cardiac surgical population. This review combines the evidence on the implications of using baseline transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) GLS in cardiac surgical populations including ischemic and structural heart disease to determine surgical outcomes. We found that results seem promising on the prognostic utility of LV strain in cardiac surgical populations. However due to the variability of study populations and outcomes, and modalities (TTE versus TEE), further research on normal versus abnormal values for different surgical populations, as well potential treatment options that may modify and potentially decrease surgical risk for those with abnormal GLS are needed.Background The management of patients with unprotected left main (LM) coronary artery disease remains challenging, with recent data casting a shadow of doubt on the safety of percutaneous coronary intervention. We aimed at describing the features of patients undergoing myocardial perfusion imaging subsequently found to have LM disease. Methods We queried our institutional database for subjects without prior revascularization or myocardial infarction (MI), who had undergone MPI followed by invasive coronary angiography within 6 months, comparing those with evidence of angiographically significant LM disease (i.e. diameter stenosis ≥50%) to those without significant coronary artery disease (CAD), or those with CAD not involving LM. Baseline, stress and imaging features were systematically collected and analyzed, and clinical outcomes (death, myocardial infarction, revascularization) sought. Results We included a total of 74 patients with LM disease, which were compared with 70 without CAD, and 920 with significant CAD not involving LM. MPI was remarbably safe in all subjects, and significant differences were found for several features, but particularly so for ST change, rate pressure product, and left ventricular ejection fraction (all p less then 0.05). Most patients with LM disease had moderate or severe ischemia, and the apical, lateral and inferior regions were the most sensitive ones. Clinical outcomes after an average of 35 months were worse in patients with LM disease than in subjects with significant CAD not involving LM, albeit non-significantly, possibly in light of the higher use of coronary artery bypass grafting. Conclusions MPI is safe and informative in patients with LM disease, and multidimensional appraisal of MPI results may guide decision-making on top of providing prognostic detail and warranty period.Background In this study, we investigated whether the frontal QRS-T angle was different between the athletes and normal healthy people. Methods The study included 122 healthy athletes (the mean age was 29.7±7.7 years, of them, were 73.8% male) and a control group consisted of 60 healthy people (the mean age was 29.8±7.8 years, of them, were 26% male). Then, the athletes were divided into two groups as who used protein supplements (PS) and those who did not. link2 In the 12-lead ECG, heart rate (HR), P, QRS, QT, corrected QT (QTc) duration, QT and corrected QT dispersion (QTD, QTcD), the sum of V1 or V2S amplitude and V5 or V6R amplitude (V1/2S+V5/6R), frontal QRS-T angle were calculated. Results There was no significant difference between the athletes and control groups regarding age, gender, smoking, body mass index, systolic blood pressure (SBP) and diastolic blood pressure (DBP), echocardiographic features, P, PR duration, P, QRS, T axis, QTD and QTcD (p>0.05).HR and QTc were significantly lower (p0.05). However, male gender was dominant in the PS users group (p=0.018). The P axis, PR and QRS duration were longer in the PS users group (p less then 0.05).It was found that the T axis was negatively correlated (r=-0.431,p less then 0.001) but the QRS axis was positively correlated (r =0.395,p less then 0.001) with frontal QRS-T angle. Conclusions The frontal QRS-T angle, was found to be wider in athletes compared to normal healthy participants. However, there was no significant difference between who used PS and those who didn't.Atherosclerosis is a major cause of disease-related mortality around the globe. The main characteristic of the disease is an accumulation of plaque on the arterial wall and subsequent erosion or rupture of some plaques. Atherosclerosis often leads to cardiovascular disease and such acute complications as myocardial infarction or ischaemic stroke due to thrombus formation. Most recent advances in atherosclerotic research state that the modifications of low- density lipoprotein (LDL) are one of the most significant stages in the disease initiation, and among these modifications desialylation is of particular interest. Sialic acids are widely expressed on all types of cells of many organisms and participate in numerous biological processes. Regarding atherosclerosis, sialidases that are responsible for the regulation of the sialic component of different molecules, are probably one of the most crucial enzymatic families. Sufficient sialylation of vascular endothelium defines its susceptibility to an atherogenic plaque formation. Moreover, the desialylation of LDL provokes an accumulation of cholesterol and lipids in the arterial walls. According to the multiple involvements of sialic acids and related enzymes, sialidases, in the initiation and development of atherosclerosis, the deeper understanding of their exact role, as well as cellular and molecular mechanisms, will allow creating more targeted and effective therapeutic and diagnostic approaches.Background Synthetic cannabinoids are part of a group of drugs called new psychoactive substances. The increase in substance use among young adults is becoming a major problem in the world. In this study we aimed to investigate the effects of synthetic cannabinoid drugs (BONSAI by in name Turkey) to electrocardiographic (ECG) parameters, in patients who were admitted to emergency service with self-reported usage of bonsai. Methods Seventy-two patients (68 males; mean age 33.8 ± 11.8) with self-reported use of bonsai and 27 (22 males; mean age 37.1 ± 8.7) age and sex-matched healthy control group enrolled the study. ECG parameters and rhythm holter were measurements calculated in both groups. Results Groups were age and sex-matched. Glucose, potassium , white blood cell count, heart rate end smoking status was significantly different in patients compared to control group. P wave max time, P wave min. time, P wave dispersion, QT max. time QT dispersion, QT corrected time and iCEB measurements (Index of Cardiac-Electrophysiological Balance) were significatly different in patient group. link3 A multivariate logistic regression analysis was used to determine independent predictors of ≥30 VPB(Ventricular premature beat)/h using parameters found to be associated with ≥30 VPB/h in a univariate analysis (potassium, QT max.time, QTc, QRS time, iCEB).In a multivariate analysis, independent predictors of ≥30 VPB/h were potassium (Odds ratio [OR] 0.107, 95% CI 0.024-0.481;P= 0.004) and iCEB (OR 4.474, 95% CI 1.752-11.429;P= 0.002). In generalize linear model β-coefficient value of interaction terms between K*iCEB has no ımportant effect on ventricular premature beats. Conclusions If the results are confirmed in further studies, iCEB seems to be a simple, easily measurable and non-invasive marker to predict cannabinoid-induced ventricular arrhythmias.Background Patients with high-risk neuroblastoma (HR NBL) treated with myeloablative regimens are reported to be at risk for cardiovascular morbidity, and this risk may be increased by impaired renal function. Procedure Long-term renal function was assessed in a national cohort of 18 (age 22.4 ± 4.9 years) HR NBL survivors by plasma creatinine (P-Cr), urea, and cystatin C (P-Cys C) concentrations, urine albumin/creatinine ratio (ACR), and estimated glomerular filtration rate (eGFR). Ambulatory blood pressure was monitored, and common carotid intima-media thickness (CIMT) and left ventricular mass index (LVMI) were evaluated. Results No significant difference in P-Cr, P-Cys C, or eGFR was found between the NBL survivors and the age- and sex-matched 20 controls. P-Cys C-based eGFR (eGFRcysc) was significantly lower than the P-Cr-based eGFRcr (97 ± 17 mL/min/1.73 m2 vs 111 ± 19 mL/min/1.73 m2 , P less then 0.001) among the NBL survivors. The eGFRcysc was below normal in 28%, and ACR was above normal in 22% of the NBL survivors. Abnormal blood pressure was found in 56% of the survivors, and an additional 17% were normotensive at daytime but had significant nocturnal hypertension. Both ACR and P-Cys C were associated with nighttime diastolic hypertension. Conclusions Long-term survivors of childhood HR NBL showed signs of only mild renal dysfunction associated with diastolic hypertension. Elevated ACR and P-Cys C were the most sensitive indicators of glomerular renal dysfunction and hypertension in this patient cohort.Objective To examine how primary care physicians define placebo concepts, use placebos in clinical practice, and view open-label placebos (OLPs). Design Semi-structured focus groups that were audio-recorded and content-coded. Methods Two focus groups with a total of 15 primary care physicians occurred at medical centres in the New England region of the United States. Prior experience using placebo treatments and attitudes towards open-label placebos were explored. Themes were analysed using an inductive data-driven approach. Results Physicians displayed a nuanced understanding of placebos and placebo effects in clinical contexts which sometimes focused on relational factors. Some respondents reported that they prescribed treatments with no known pharmacological effect for certain conditions and symptoms ('impure placebos') and that such prescriptions were more common for pain disorders, functional disorders, and medically unexplained symptoms. Opinions about OLP were mixed Some viewed OLPs favourably or considered them 'harmless'; however, others strongly rejected OLPs as disrespectful to patients.
