Background: Cardiovascular complication is a major consequence of cancer treatment. Anthracycline induced cardiomyopathy is a known cause of long term morbidity and mortality among cancer survivors. The burden of this complication is unknown in our setting Objective: This study aimed to determine the prevalence of cardiomyopathy in ambulatory patients treated with anthracycline (Ac) containing chemotherapy at Kenyatta National Hospital (KNH) as measured by two dimensional (2D) echocardiography (ECHO). Study design: A hospital based inpatient/outpatient cross sectional, descriptive study. Study setting: This study was carried out in various outpatient clinics and oncology wards in Kenyatta National Hospital. These included the adult hematooncology clinic 23, Ground floor C (GF-C), Ward 8C and Ground floor D (GF-D) Subjects: The study population included patients who have been exposed to Ac. The minimum Ac dose was 200mg/m2. A total of 129 patients with various types of cancers were sampled consecutively over a period of 3 months. Eligible patients underwent a 2D ECHO and left ventricular ejection fraction (LVEF) was assessed. Results: Patients between the ages of 15 and 75 participated in the study, the mean age was 45.6 years, with the female to male ratio of 4.3:1. Majority of the patients had breast cancer (67.4%) and the treatment regimen in over 65% of them was doxorubicin and cyclophospomide (AC). The mean cumulative dose was 236mg/m2. All patients recruited had received a cumulative dose of between 200 - 450mg/m2. Most of the patients (63%) had completed Ac within one year of their cardiac evaluation. Only 14.0 % of the patients had a pretreatment ECHO. The overall prevalence of LV systolic dysfunction detected by echocardiography was 3.1% (95% CI 0.9– 7.8). The study was not powered to make associations with age, sex and cumulative dose and presence of cardiomyopathy. Conclusions: The study demonstrates a prevalence of 3.1% cardiomyopathy among cancer patients treated with anthracyclines. This figure is comparable to similar studies done. The prevalence described in most studies ranges from between 1% to 20.5%.Anthar

Abstract Background Anthracycline therapies cause myocardial damage and the onset of heart failure, depending on their doses. We investigated prognostic factors for cancer therapeutics-related cardiac dysfunction (CTRCD) in patients receiving modern anthracycline therapies. Methods Of 472 breast cancer patients with complete data treated with anthracycline, 8 were diagnosed with CTRCD. Results Multivariate regression analyses revealed that the anthracycline cumulative dose, concomitant use of molecular targeted drugs and a prechemotherapy left ventricular ejection fraction < 50% were independent and significant predictors of the onset of CTRCD. Conclusions Even in the modern era, the anthracycline cumulative dose is an independent risk factor for the onset of CTRCD.

Background: Anthracyclines are widely used chemotherapeutic agents in several cancers. Since its use, survival improved significantly among cancer patients and has been reported to be up to 80%. However, anthracyclines possess several cardiac, renal and hematological toxicities which limit their use in practice. Cardiotoxicity is still the most important and dose-limiting side effect of anthracycline treatment. Here we aimed to investigate the frequency of anthracyclineinduced cardiomyopathy in pediatric malignancies in Khuzestan Province, Iran. Methods: A total of 112 patients were enrolled in the present study. Patients were allocated to the case or control group based on receiving anthracycline. Echocardiographic examinations were performed by a cardiologist. Electrocardiograms were also recorded. Results: We showed that cancer patients who underwent anthracycline treatment showed cardiomyopathy as defined by lower LVEF (Left Ventricular Ejection Fraction) among patients (p = 0.041). Abnormal LVEF was reported with a frequency of about 9.5% in patients (p = 0.026). However, LVFS (Left Ventricular Fraction Shortening), QRS voltage and QT interval did not differ significantly between treatment and control groups. Our data analysis revealed that this difference is mainly related to high cumulative dose since high cumulative dose of anthracycline (>300 mg/m2) leads to lower LVEF and LVFS and higher QRS voltage in comparison with lower cumulative dose (<300 mg/m2) and control group; but there was no significant difference between low dose and control group. Different age groups and type of malignancy including hematological and solid tumors did not show any significant differences for echocardiographic and electrocardiograms parameters. Conclusion: In our study, lower LVEF among patients who received anthracyclines were mainly related to a high cumulative dose of anthracyclines, which emphasizes the effect of cumulative dose for cardiotoxic effects. Larger studies are needed to investigate possible other risk factors for cardiotoxicity.

Abstract Background The CBR3 V244M single nucleotide polymorphism has been linked to the risk of anthracycline-related cardiomyopathy in survivors of childhood cancer. There have been limited prospective studies examining the impact of CBR3 V244M on the risk for anthracycline-related cardiotoxicity in adult cohorts. Objectives This study evaluated the presence of associations between CBR3 V244M genotype status and changes in echocardiographic parameters in breast cancer patients undergoing doxorubicin treatment. Methods We recruited 155 patients with breast cancer receiving treatment with doxorubicin (DOX) at Roswell Park Comprehensive Care Center (Buffalo, NY) to a prospective single arm observational pharmacogenetic study. Patients were genotyped for the CBR3 V244M variant. 92 patients received an echocardiogram at baseline (t0 month) and at 6 months (t6 months) of follow up after DOX treatment. Apical two-chamber and four-chamber echocardiographic images were used to calculate volumes and left ventricular ejection fraction (LVEF) using Simpson’s biplane rule by investigators blinded to all patient data. Volumetric indices were evaluated by normalizing the cardiac volumes to the body surface area (BSA). Results Breast cancer patients with CBR3 GG and AG genotypes both experienced a statistically significant reduction in LVEF at 6 months following initiation of DOX treatment for breast cancer compared with their pre-DOX baseline study. Patients homozygous for the CBR3 V244M G allele (CBR3 V244) exhibited a further statistically significant decrease in LVEF at 6 months following DOX therapy in comparison with patients with heterozygous AG genotype. We found no differences in age, pre-existing cardiac diseases associated with myocardial injury, cumulative DOX dose, or concurrent use of cardioprotective medication between CBR3 genotype groups. Conclusions CBR3 V244M genotype status is associated with changes in echocardiographic parameters suggestive of early anthracycline-related cardiomyopathy in subjects undergoing chemotherapy for breast cancer.

Anthracycline-based regimens with or without anti-human epidermal growth factor receptor (HER) 2 agents such as trastuzumab are effective in breast cancer treatment. Nevertheless, heart failure (HF) has become a significant side effect of these regimens. This study aimed to investigate the incidence and factors associated with HF in breast cancer patients treated with anthracyclines with or without trastuzumab. A retrospective cohort study was performed in patients with breast cancer who were treated with anthracyclines with or without trastuzumab between 1 January 2014 and 31 December 2018. The primary outcome was the incidence of HF. The secondary outcome was the risk factors associated with HF by using the univariable and multivariable cox-proportional hazard model. A total of 475 breast cancer patients were enrolled with a median follow-up time of 2.88 years (interquartile range (IQR), 1.59–3.93). The incidence of HF was 3.2%, corresponding to an incidence rate of 11.1 per 1000 person-years. The increased risk of HF was seen in patients receiving a combination of anthracycline and trastuzumab therapy, patients treated with radiotherapy or palliative-intent chemotherapy, and baseline left ventricular ejection fraction <65%, respectively. There were no statistically significant differences in other risk factors for HF, such as age, cardiovascular comorbidities, and cumulative doxorubicin dose. In conclusion, the incidence of HF was consistently high in patients receiving combination anthracyclines trastuzumab regimens. A reduced baseline left ventricular ejection fraction, radiotherapy, and palliative-intent chemotherapy were associated with an increased risk of HF. Intensive cardiac monitoring in breast cancer patients with an increased risk of HF should be advised to prevent undesired cardiac outcomes.

Abstract Purpose Cardiotoxicity affects 5–16% of cancer patients who receive anthracyclines and/or trastuzumab. Limited research has examined interventions to mitigate cardiotoxicity. We examined the role of statins in mitigating cardiotoxicity by performing a systematic review and meta-analysis of published studies. Methods A literature search was conducted using PubMed, Embase, Web of Science, ClinicalTrials.gov, and Cochrane Central. A random-effect model was used to assess summary relative risks (RR), weighted mean differences (WMD), and corresponding 95% confidence intervals. Testing for heterogeneity between the studies was performed using Cochran’s Q test and the I2 test. Results Two randomized controlled trials (RCTs) with a total of 117 patients and four observational cohort studies with a total of 813 patients contributed to the analysis. Pooled results indicate significant mitigation of cardiotoxicity after anthracycline and/or trastuzumab exposure among statin users in cohort studies [RR = 0.46, 95% CI (0.27–0.78), p = 0.004, $${ }I^{2}$$ I 2  = 0.0%] and a non-significant decrease in cardiotoxicity risk among statin users in RCTs [RR = 0.49, 95% CI (0.17–1.45), p = 0.20, $$I^{2}$$ I 2  = 5.6%]. Those who used statins were also significantly more likely to maintain left ventricular ejection fraction compared to baseline after anthracycline and/or trastuzumab therapy in both cohort studies [weighted mean difference (WMD) = 6.14%, 95% CI (2.75–9.52), p < 0.001, $$I^{2}$$ I 2  = 74.7%] and RCTs [WMD = 6.25%, 95% CI (0.82–11.68, p = 0.024, $$I^{2}$$ I 2  = 80.9%]. We were unable to explore publication bias due to the small number of studies. Conclusion This meta-analysis suggests that there is an association between statin use and decreased risk of cardiotoxicity after anthracycline and/or trastuzumab exposure. Larger well-conducted RCTs are needed to determine whether statins decrease risk of cardiotoxicity from anthracyclines and/or trastuzumab.

Background: Hyperuricemia is an established risk factor for cardiovascular disease, including atrial fibrillation (AF). The prevalence of hyperuricemia and its clinical significance in patients with already diagnosed AF remain unexplored. Methods: The Polish Atrial Fibrillation (POL-AF) registry includes consecutive patients with AF hospitalized in 10 Polish cardiology centers from January to December 2019. This analysis included patients in whom serum uric acid (SUA) was measured. Results: From 3999 POL-AF patients, 1613 were included in the analysis. The mean age of the subjects was 72 ± 11.6 years, and the mean SUA was 6.88 ± 1.93 mg/dL. Hyperuricemia was found in 43% of respondents. Eighty-four percent of the respondents were assigned to the high cardiovascular risk group, and 45% of these had SUA >7 mg/dL. Comparison of the extreme SUA groups (<5 mg/dL vs. >7 mg/dL) showed significant differences in renal parameters, total cholesterol concentration, and left ventricular ejection fraction (EF). Multivariate regression analysis showed that SUA >7 mg/dL (OR 1.74, 95% CI 1.32–2.30) and GFR <60 mL/min/1.73 m2 (OR 1.94, 95% CI 1.46–2.48) are significant markers of EF <40% in the study population. Female sex was a protective factor (OR 0.74, 95% CI 0.56–0.97). The cut-off point for SUA with 60% sensitivity and specificity indicative of an EF <40% was 6.9 mg/dL. Conclusions: Although rarely assessed, hyperuricemia appears to be common in patients with AF. High SUA levels may be a significant biomarker of reduced left ventricular EF in AF patients.

Purpose The purpose of this analysis was to investigate trastuzumab-associated cardiac adverse effects in breast cancer patients after completion of (neo)adjuvant chemotherapy with or without radiotherapy. Patients and Methods The Herceptin Adjuvant (HERA) trial is a three-group, multicenter, open-label randomized trial that compared 1 or 2 years of trastuzumab given once every 3 weeks with observation in patients with HER-2–positive breast cancer. Only patients who after completion of (neo)adjuvant chemotherapy with or without radiotherapy had normal left ventricular ejection fraction (LVEF ≥ 55%) were eligible. A repeat LVEF assessment was performed in case of cardiac dysfunction. Results Data were available for 1,693 patients randomly assigned to 1 year trastuzumab and 1,693 patients randomly assigned to observation. The incidence of trastuzumab discontinuation due to cardiac disorders was low (4.3%). The incidence of cardiac end points was higher in the trastuzumab group compared with observation (severe congestive heart failure [CHF], 0.60% v 0.00%; symptomatic CHF, 2.15% v 0.12%; confirmed significant LVEF drops, 3.04% v 0.53%). Most patients with cardiac dysfunction recovered in fewer than 6 months. Patients with trastuzumab-associated cardiac dysfunction were treated with higher cumulative doses of doxorubicin (287 mg/m2 v 257 mg/m2) or epirubicin (480 mg/m2 v 422 mg/m2) and had a lower screening LVEF and a higher body mass index. Conclusion Given the clear benefit in disease-free survival, the low incidence of cardiac adverse events, and the suggestion that cardiac dysfunction might be reversible, adjuvant trastuzumab should be considered for treatment of breast cancer patients who fulfill the HERA trial eligibility criteria.

AbstractObjective: to describe self-care behavior and its associated factors in a sample of heart failure Brazilian patients.Method: descriptive cross-sectional study with non-probabilistic sample of 116 ambulatory patients undergoing heart failure treatment. Self-care was evaluated using the Self-Care of Heart Failure Index, (scores ≥70 points=appropriate self-care). Association tests were applied, considering a descriptive level of 0.05.Results: the mean age of participants was 57.7 (SD =11.3) years; 54.3% were male; the mean schooling was 5.5 (SD = 4.0) years; and 74.1% had functional class II-III. The mean scores on the subscales of the Self-Care of Heart Failure Index indicated inappropriate self-care (self-care maintenance: 53.2 (SD =14.3), selfcare management: 50.0 (SD = 20.3) and self-care confidence: 52.6 (SD=22.7)) and it was found low frequencies of participants with appropriate self-care (self-care maintenance, 6.9%), self-care management (14.7%) and self-care confidence (19%). Higher scores of the Self-Care of Heart Failure Index were associated with: reduced left ventricular ejection fraction (p=0.001), longer time of experience with the disease (p=0.05) and joint monitoring by physician and nurse (p=0.007).Conclusion: investments are needed to improve the self-care behavior and the nursing can play a relevant role in this improvement.

Background: It has been reported that mechanical dispersion of myocardial contraction is increased in failing myocardium. However little is known about the association between contractile entropy evaluated by myocardial scintigraphy and prognosis in patients with non-ischemic dilated cardiomyopathy (NIDCM). Purpose: We aimed to investigate the prognostic value of contractile entropy in patients with NIDCM. Methods: Forty-seven patients (38 male, 55.1 years) with NIDCM were performed gated 99mTc-sestamibi myocardial perfusion SPECT (GMPS) and endomyocardial biopsy. Entropy was automatically calculated as a result of contractile phase analysis for each myocardial sampling point from GMPS, and it reflects a dispersion of global mechanical contraction. All patients were allocated into two groups based on the median of entropy; HE-group: entropy≥0.61 and LE-group: entropy<0.61. All patients were followed up at the mean of 2.8 years. Results: The mean QRS duration, left ventricular ejection fraction (LVEF) and plasma brain natriuretic peptide (BNP) levels were 114 msec, 35% and 225 pg/mL, respectively. Although there were no significant differences in QRS duration and plasma BNP levels between the two groups, LVEF was lower in the HE-group than in the LE-group (31.1% vs 39.8%, p=0.002). In Kaplan-Meier survival analysis, cardiac event rate was significantly higher in the HE-group (Figure). Cox proportional hazard analysis revealed that the HE-group was a significant determinant of cardiac events (Hazard Ratio: 7.66; 95%CI: 0.070-2.532; p=0.033). The mRNA expression level of sarcoplasmic endoplasmic reticulum Ca2+ ATPase (SERCA2a) in biopsy specimens was significantly lower in the LE-group (p=0.015). Conclusion: Contractile entropy, reflecting an impairment of global left ventricular contraction, might be useful to predict a poor prognosis in patients with NIDCM.
