- Cancer Patients with Acute Coronary Syndrome Have Non-Superior Bleeding Risk Compared to Patients with Similar Characteristics - a Propensity Score Analysis from the ProACS RegistryPublication . Mano, T; Timóteo, AT; Aguiar Rosa, S; Belo, A; Cruz Ferreira, R; ProACS Registry InvestigatorsIntroduction: The management of acute coronary syndrome (ACS) in malignancy is challenging due to higher bleeding risk. Methods: We analyzed patients with cancer (active or in the previous five years) prospectively included in the ProACS registry between 2010 and 2019. Our aim was to assess safety (major bleeding, primary endpoint) and secondary efficacy endpoints (in-hospital mortality and combined in-hospital mortality, reinfarction and ischemic stroke) of ACS treatment. Propensity score matching analysis (1:1) was further performed to better understand predictors of outcomes. Results: We found 934 (5%) cancer patients out of a total of 18 845 patients with ACS. Cancer patients had more events: major bleeding (2.9% vs. 1.5%), in-hospital mortality (5.8% vs. 3.4%) and the combined endpoint (7.4% vs. 4.9%). The primary endpoint was related to cancer diagnosis (OR 1.97), previous bleeding (OR 7.09), hemoglobin level (OR 4.94), atrial fibrillation (OR 3.50), oral anticoagulation (OR 3.67) and renal dysfunction. Mortality and the combined secondary endpoint were associated with lower use of invasive coronary angiography and antiplatelet and neurohormonal blocker therapy. After propensity score matching (350 patients), there were no statistically significant differences in endpoints between the populations. Conclusion: Bleeding risk was not significant higher in the cancer population compared to patients with similar characteristics, nor were mortality or ischemic risk. The presence of cancer should not preclude simultaneous ACS treatment.
- Cardiac Magnetic Resonance in the Assessment of Pericardial Abnormalities: a Case SeriesPublication . Mano, T; Santos, H; Aguiar Rosa, S; Thomas, B; Baquero, LBackground: Cardiac magnetic resonance (CMR) has a unique role in evaluating pericardial disease, permitting non-invasive tissue analysis, and haemodynamic assessment. Case summary: In Case 1 of recurrent pericarditis, CMR confirmed reactivation of inflammation with late gadolinium enhancement and native T1/T2 mapping techniques, prompting therapeutic changes. In constrictive pericarditis, CMR is the only modality capable of differentiating a subacute potentially reversible form (Case 2), from a chronic, burnt out irreversible phase characterized by constrictive physiology (Case 3). Discussion: Cardiac magnetic resonance is an effective tool to tailor individual therapy, particularly in cases of recurrent and constrictive pericarditis. Late gadolinium enhancement provides diagnostic and prognostic information, and multiparametric mapping has emerged as a promising tool with incremental diagnostic value.
- Cardiovascular Primary Prevention - Directed Approach for Individual FeaturesPublication . Mano, T; Aguiar Rosa, S; Rio, P; Timóteo, AT; Cruz Ferreira, RCardiovascular diseases (CVD) remain the leading cause of morbimortality globally. Despite substantial improvement in outcomes, alarming increases in obesity, diabetes mellitus and other risk factors have been noted in recent years. Despite the majority of CVD being preventable and primary prevention being cost-effective, preventive approaches are poorly implemented in the population at large as well as in individual patients. The pillar of prevention is lifestyle changes (diet, weight, smoking and exercise) followed by, when appropriate, targeting of the main cardiovascular risk factors with pharmacotherapy: lipid lowering therapy, blood-pressure treatment and blood glucose control. Low-dose aspirin as “one-dose-fits-all strategy” remains controversial as primary prevention due to the increased bleeding risk. New scoring systems or further application of imaging techniques (for example, coronary calcium score) are necessary for better risk stratification.

- Efficacy of Peritoneal Dialysis in Patients With Refractory Congestive Heart Failure: a Systematic Review and Meta-AnalysisPublication . Timóteo, AT; Mano, T; SpringerRefractory congestive heart failure (RCHF) is a common complication in the natural history of advanced heart failure. Peritoneal dialysis (PD) is a possible alternative in those patients, but studies are scarce, and mostly with small samples. We conducted this meta-analysis to evaluate the effects of PD in patients with RCHF. Articles published before July 2020 in the following databases: PubMed, Web of Science, and CENTRAL. Mean differences (MD) and 95% confidence intervals (CIs) were computed to generate a pooled effect size with a random effects model. We also assessed heterogeneity, risk of bias, publication bias, and quality of evidence. Twenty observational studies (n = 769) were included, with a "before and after intervention" design. PD was associated with a significant reduction in NYHA functional class (MD -1.37, 95% CI -0.78 to -1.96) and length of hospitalisation (MD -34.8, 95% CI -20.6 to -48.9 days/patient/year), a small but significant increase in left ventricular ejection fraction (MD 4.3, 95%CI 1.9 to 6.8%) and a non-significant change in glomerular filtration rate (MD -3.0, 95% CI -6.0 to 0 mL/min/1.73m2). Heterogeneity among studies was significant and overall risk of bias was rated from moderate to critical. No significant publication bias was found, and the overall quality of evidence was very low for all outcomes. PD in patients with RCHF improved functional class, length of hospitalisation, and ventricular functional, and had no impact in renal function. Further randomised clinical trials are warranted to confirm our results that showed some limitations.
- Myocardial Work Brings New Insights into Left Ventricular Remodelling in Cardio-Oncology PatientsPublication . Vaz Ferreira, V; Mano, T; Cardoso, I; Coutinho Cruz, M; Branco, LM; Almeida-Morais, L; Timóteo, AT; Galrinho, A; Castelo, A; Garcia Brás, P; Simão, D; Sardinha, M; Gonçalves, A; Cruz Ferreira, RSerial transthoracic echocardiographic (TTE) assessment of 2D left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) are the gold standard screening methods for cancer therapeutics-related cardiac dysfunction (CTRCD). Non-invasive left ventricular (LV) pressure-strain loop (PSL) provides a novel method of quantifying myocardial work (MW) with potential advantages to evaluate the impact of cardiotoxic treatments on heart function. We prospectively assessed breast cancer female patients undergoing cancer therapy through serial monitoring by 2D and 3D TTE. Patients were evaluated at T0, T1 and T2 (before, 4-6 and 12-14 months after starting therapy, respectively). Through PSL analysis, MW indices were calculated. A total of 122 patients, with a mean age of 54.7 years, who received treatment with anthracyclines (77.0%) and anti-HER2 (75.4%) were included. During a mean follow-up of 14.9 ± 9.3 months, LVEF and GLS were significantly diminished, and 29.5% developed CTRCD. All MW indices were significantly reduced at T1 compared with baseline and tended to return to baseline values at T2. Global work index and global work efficiency showed a more pronounced variation in patients with CTRCD. The presence of more than one cardiovascular risk factor, obesity and baseline left atrium volume were predictors of changes in MW parameters. In conclusion, breast cancer treatment was associated with LV systolic dysfunction as assessed by MW, with its peak at 4-6 months and a partial recovery afterwards. Assessment of myocardial deformation parameters allows a more detailed characterization of cardiac remodelling and could enhance patient screening and selection for cardioprotective therapeutics.
- Not All Pseudoaneurysms Are Femoral. A Transcaval Transcatheter Aortic Valve Replacement Rare ComplicationPublication . Mano, T; Ramos, R; Cacela, D; Patrício, LWe report a case of a 73-year-old male with multiple comorbidities, including postpoliomyelitis severe scoliosis, referred to our tertiary center due to a severe symptomatic aortic stenosis, considered high risk for surgical aortic valve replacement (AVR). Due to unsuitable femoral and subclavian accesses, the patient underwent a transcaval transcatheter AVR (TAVR) procedure, complicated by the development of an iatrogenic infrarenal aortic pseudoaneurysm with aortocaval fistula. Scoliosis can cause varying anatomic relationships between retroperitoneal vessels and intervertebral disk spaces, which increase the difficulty of the procedure and consequently lead to this vascular complication. Although most aortocaval fistulas close spontaneously after 1 year, the risk of pseudoaneurysm rupture in this critical area was crucial in the decision of a new successful percutaneous aortic stent intervention.
- Prognostic Power of Anaerobic Threshold Parameters in Patients with Transposition of the Great Arteries and Systemic Right VentriclePublication . Valentim Gonçalves, A; Mano, T; Agapito, A; Aguiar Rosa, S; Sousa, L; Rio, P; Oliveira, JA; Monteiro, A; Pereira-da-Silva, T; Ilhão Moreira, R; Soares, R; Pinto, MF; Cruz Ferreira, RINTRODUCTION: Both transposition of the great arteries (TGA) previously submitted to a Senning/Mustard procedure and congenitally corrected TGA (cc-TGA) have the systemic circulation supported by the morphological right ventricle, thereby rendering these patients to heart failure events risk. The aim of this study was to evaluate cardiopulmonary exercise test parameters for stratifying the risk of heart failure events in TGA patients. METHODS: Retrospective evaluation of adult TGA patients with systemic circulation supported by the morphological right ventricle submitted to cardiopulmonary exercise test in a tertiary centre. Patients were followed up for at least 1 year for the primary endpoint of cardiac death or heart failure hospitalisation. Several cardiopulmonary exercise test parameters were analysed as potential predictors of the combined endpoint and their predictive power were compared (area under the curve). RESULTS: Cardiopulmonary exercise test was performed in 44 TGA patients (8 cc-TGA), with a mean age of 35.1 ± 8.4 years. The primary endpoint was reached by 10 (22.7%) patients, with a mean follow-up of 36.7 ± 26.8 months. Heart rate at anaerobic threshold had the highest area under the curve value (0.864), followed by peak oxygen consumption (pVO2) (0.838). Heart rate at anaerobic threshold ≤95 bpm and pVO2 ≤20 ml/kg/min had a sensitivity of 87.5 and 80.0% and a specificity of 82.4 and 76.5%, respectively, for the primary outcome. CONCLUSION: Heart rate at anaerobic threshold ≤95 bpm had the highest predictive power of all cardiopulmonary exercise test parameters analysed for heart failure events in TGA patients with systemic circulation supported by the morphological right ventricle.
