- Effects of anthracycline, cyclophosphamide and taxane chemotherapy on QTc measurements in patients with breast cancer(2018) VERONESE, Pedro; HACHUL, Denise Tessariol; SCANAVACCA, Mauricio Ibrahim; HAJJAR, Ludhmila Abrahao; WU, Tan Chen; SACILOTTO, Luciana; VERONESE, Carolina; DARRIEUX, Francisco Carlos da CostaAim Acute and subacute cardiotoxicity are characterized by prolongation of the corrected QT interval (QTc) and other measures derived from the QTc interval, such as QTc dispersion (QTdc) and transmural dispersion of repolarization (DTpTe). Although anthracyclines prolong the QTc interval, it is unclear whether breast cancer patients who undergo the ACT chemotherapy regimen of anthracycline (doxorubicin: A), cyclophosphamide (C) and taxane (T) may present with QTc, QTdc and DTpTe prolongation. Methods Twenty-three consecutive patients with breast cancer were followed prospectively during ACT chemotherapy and were analyzed according to their QT measurements. QTc, QTdc and DTpTe measurements were determined by a 12-lead electrocardiogram (EKG) prior to chemotherapy (baseline), immediately after the first phase of anthracycline and cyclophosphamide (AC) treatment, and immediately after T treatment. Serum troponin and B-type natriuretic peptide (BNP) levels were also measured. Results Compared to baseline values, the QTc interval was significantly prolonged after the AC phase (439.7 +/- 33.2 ms vs. 472.5 +/- 36.3 ms, p = 0.001) and after T treatment (439.7 +/- 33.2 ms vs. 467.9 +/- 42.6 ms, p < 0.001). Troponin levels were elevated after the AC phase (23.0 pg/mL [min-max: 6.0-85.0] vs. 6.0 pg/mL [min-max: 6.0-22.0], p < 0.001) and after T treatment (25.0 pg/mL [min-max: 6.0-80.0] vs. 6.0 pg/mL [min-max: 6.0-22.0], p < 0.001) compared to baseline values. Conclusion In this prospective study of patients with non-metastatic breast cancer who underwent ACT chemotherapy, significant QTc prolongation and an elevation in serum troponin levels were observed.
conferenceObject Brugada syndrome: value of electrophysiologic study in the risk stratification(2017) PAIXAO, G.; LAMES, C.; ROSA, X.; SACILOTTO, L.; DARRIEUX, F.; CHORK, M.; WU, T. C.; PISANI, C.; HACHUL, D.; SCANAVACCA, M.- 2020 APHRS/HRS expert consensus statement on the investigation of decedents with sudden unexplained death and patients with sudden cardiac arrest, and of their families(2021) STILES, Martin K.; WILDE, Arthur A. M.; ABRAMS, Dominic J.; ACKERMAN, Michael J.; ALBERT, Christine M.; BEHR, Elijah R.; CHUGH, Sumeet S.; CORNEL, Martina C.; GARDNER, Karen; INGLES, Jodie; JAMES, Cynthia A.; JUANG, Jyh-Ming Jimmy; KAAB, Stefan; KAUFMAN, Elizabeth S.; KRAHN, Andrew D.; LUBITZ, Steven A.; MACLEOD, Heather; MORILLO, Carlos A.; NADEMANEE, Koonlawee; PROBST, Vincent; V, Elizabeth Saarel; SACILOTTO, Luciana; SEMSARIAN, Christopher; SHEPPARD, Mary N.; SHIMIZU, Wataru; SKINNER, Jonathan R.; TFELT-HANSEN, Jacob; WANG, Dao WuThis international multidisciplinary document intends to provide clinicians with evidence-based practical patient-centered recommendations for evaluating patients and decedents with (aborted) sudden cardiac arrest and their families. The document includes a framework for the investigation of the family allowing steps to be taken, should an inherited condition be found, to minimize further events in affected relatives. Integral to the process is counseling of the patients and families, not only because of the emotionally charged subject, but because finding (or not finding) the cause of the arrest may influence management of family members. The formation of multidisciplinary teams is essential to provide a complete service to the patients and their families, and the varied expertise of the writing committee was formulated to reflect this need. The document sections were divided up and drafted by the writing committee members according to their expertise. The recommendations represent the consensus opinion of the entire writing committee, graded by Gass of Recommendation and Level of Evidence. The recommendations were opened for public comment and reviewed by the relevant scientific and clinical document committees of the Asia Pacific Heart Rhythm Society (APHRS) and the Heart Rhythm Society (HRS); the document underwent external review and endorsement by the partner and collaborating societies. While the recommendations are for optimal care, it is recognized that not all resources will be available to all clinicians. Nevertheless, this document articulates the evaluation that the clinician should aspire to provide for patients with sudden cardiac arrest, decedents with sudden unexplained death, and their families.
- Age is associated with time in therapeutic range for warfarin therapy in patients with atrial fibrillation(2016) MARCATTO, Leiliane Rodrigues; SACILOTTO, Luciana; DARRIEUX, Francisco Carlos da Costa; HACHUL, Denise Tessariol; SCANAVACCA, Mauricio Ibrahim; KRIEGER, Jose Eduardo; PEREIRA, Alexandre Costa; SANTOS, Paulo Caleb Junior LimaBackground: Warfarin is the most prescribed oral anticoagulant used for preventing stroke in patients with atrial fibrillation. Time in the therapeutic range (TTR) has been accepted as the best method to evaluate the quality of warfarin therapy. The main aim of the present study was to evaluate the impact of variables on the time in the therapeutic range for warfarin therapy in patients with atrial fibrillation from a referral cardiovascular hospital. Methods: This retrospective study included 443 patients were included (190 patients with age < 65 years and 253 patients with age >= 65 years) from 2011 to 2014 and TTR was computed according to Rosendaal's method. Results: Patients with age >= 65 years had higher TTR value (67+/-22%) compared with patients with < 65 years (60+/-24%) (p = 0.004). In a linear regression model, only age >= 65 years emerged as a significant predictor of greater TTR values. In multivariate logistic regression model, the variable age = 65 years was associated with higher OR for having a TTR higher than the median value (OR = 2.17, p < 0.001). Conclusion: We suggest that the age influenced TTR through greater drug adherence. Strategies for increasing drug adherence might improve quality of warfarin anticoagulation.
- Nonstructural Genetic Cardiac Disease as the Most Common Cause of Sudden Cardiac Death in the Young Athlete: Is This True?(2023) STEIN, Ricardo; FERRARI, Filipe; BEUREN, Thais M. A.; SILVEIRA, Anderson D. D. da; SACILOTTO, LucianaPurpose of reviewThis review is aimed at summarizing and discussing the primary causes of sudden cardiac death (SCD) in young athletes.Recent findingsSCD in young athletes is a dramatic event, with an incidence rate that can reach 13 deaths per 100,000 athletes. Occasionally, exercise can trigger SCD, and unfortunately, this event may be the first manifestation of an underlying and silent cardiac condition. In the USA, hypertrophic cardiomyopathy is reported as the leading cause of SCD among young athletes, whereas arrhythmogenic right ventricular cardiomyopathy has been reported as the main cause in the Veneto region of Italy. However, emerging evidence has demonstrated that in many cases, athletes who experience sudden death have a seemingly normal cardiac structure, suggesting the possibility of sudden arrhythmic death syndrome. In recent decades, it has been possible to determine the causes of many SCDs that occur in the presence of nonstructural cardiac diseases. It is worth noting that routinely used cardiovascular screening methods, such as electrocardiogram and echocardiogram, may fail to detect nonstructural genetic cardiac diseases. In turn, in some circumstances, genetic testing may play a role in identifying individuals at risk of SCD due to these conditions.Understanding the underlying causes of SCD in young athletes is noteworthy for developing effective prevention and screening strategies. A multidisciplinary approach involving cardiologists, clinical sports physicians, pathologists, and geneticists collaborating represents an opportunity to enhance and optimize patient care and can play a crucial role in the prevention of SCD among young athletes.
- Compound Heterozygous SCN5A Mutations in a Toddler - Are they Associated with a More Severe Phenotype?(2017) SACILOTTO, Luciana; EPIFANIO, Hindalis Ballesteros; DARRIEUX, Francisco Carlos da Costa; WULKAN, Fanny; OLIVEIRA, Theo Gremen Mimary; HACHUL, Denise Tessariol; PEREIRA, Alexandre da Costa; SCANAVACCA, Mauricio IbrahimCompound heterozygosity has been described in inherited arrhythmias, and usually associated with a more severe phenotype. Reports of this occurrence in Brugada syndrome patients are still rare. We report a study of genotype-phenotype correlation after the identification of new variants by genetic testing. We describe the case of an affected child with a combination of two different likely pathogenic SCN5A variants, presenting sinus node dysfunction, flutter and atrial fibrillation, prolonged HV interval, spontaneous type 1 Brugada pattern in the prepubescent age and familiar history of sudden death.

- Evaluation of a pharmacogenetic-based warfarin dosing algorithm in patients with low time in therapeutic range - study protocol for a randomized controlled trial(2016) MARCATTO, Leiliane Rodrigues; SACILOTTO, Luciana; BUENO, Carolina Tosin; FACIN, Mirella; STRUNZ, Celia Maria Cassaro; DARRIEUX, Francisco Carlos Costa; SCANAVACCA, Mauricio Ibrahim; KRIEGER, Jose Eduardo; PEREIRA, Alexandre Costa; SANTOS, Paulo Caleb Junior LimaBackground: Time in therapeutic range (TTR) is a measurement of quality of warfarin therapy and lower TTR values (<50%) are associated with greater risk of thromboembolic and bleeding events. Recently, we developed a pharmacogenetic-based warfarin dosing algorithm specifically calibrated for a Brazilian patient sample. The aims of this study are: to evaluate the impact of a genetic-based algorithm, compared to traditional anticoagulation, in the time to achieve the therapeutic target and in TTR percentage; and to assess the cost-effectiveness of genotype-guided warfarin dosing in a specific cohort of patients with low TTR (<50%) from a tertiary cardiovascular hospital. Methods/design: This study is a randomized controlled trial in patients (n = 300) with atrial fibrillation with TTR <50%, based on the last three INR values. At the first consultation, patients will be randomized into two groups: TA group (traditional anticoagulation) and PA group (pharmacogenetic anticoagulation). For the first group, the physician will adjust the dose according to current INR value and, for the second group, a pharmacogenetic algorithm will be used. At the second, third, fourth and fifth consultations (with an interval of 7 days each) INR will be measured and, if necessary, the dose will be adjusted based on guidelines. Afterwards, patients who are INR stable will begin measuring their INR in 30 day intervals; if the patient's INR is not stable, the patient will return in 7 days for a new measurement of the INR. Outcomes measures will include the time to achieve the therapeutic target and the percentage of TTR at 4 and 12 weeks. In addition, as a secondary end-point, pharmacoeconomic analysis will be carried out. Ethical approval was granted by the Ethics Committee for Medical Research on Human Beings of the Clinical Hospital of the University of Sao Paulo Medical School. Discussion: This randomized study will include patients with low TTR and it will evaluate whether a population-specific genetic algorithm might be more effective than traditional anticoagulation for a selected group of poorly anticoagulated patients.
