RESUMO

BACKGROUND: Brugada syndrome (BrS) is associated with abnormal electrophysiological properties at right ventricular epicardium, consisting of fragmented electrograms extending well beyond QRS termination. We aimed to evaluate the utility of signal-averaged electrocardiogram (SA-ECG) for the noninvasive assessment of late potentials (LP) and risk stratification of BrS patients. METHODS: A prospective, observational, single-center study of BrS patients is submitted to SA-ECG with the determination of the total filtered QRS duration (fQRS), root mean square voltage of the 40 ms terminal portion of the QRS (RMS40), and duration of the low-amplitude electric potential component of the terminal portion of the QRS (LAS40). LP were considered positive when above standard cut-offs: fQRS > 114 ms, RMS40 < 20 µV, and LAS40 > 38 ms. The rates of malignant arrhythmic events (MAEs), defined as sudden death or appropriate shocks, were compared in relation to clinical characteristics and SA-ECG findings. RESULTS: A total of 106 BrS patients (mean age, 48 ± 12 years, 67.9% male) were studied, 49% with type-1 spontaneous pattern and 81% asymptomatic. During a median follow up of 4.7 years, 10 patients (7.1%) suffered MAEs, including 4 sudden deaths. The presence of LP was significantly associated with the arrhythmic risk, which increased with the number of altered LP criteria. In comparison to the patients who had none or 1 altered LP criterium, MAE risk was 4.7 times higher in those with 2 altered criteria and 9.4 times higher in those with 3 altered LP criteria. CONCLUSIONS: SA-ECG may be a useful tool for risk stratification in BrS. The presence of 2 or 3 abnormal LP criteria could identify a subset of asymptomatic patients at high risk of arrhythmic events.

RESUMO

Isolated coronary arteritis without systemic involvement in adults is exceedingly rare. A 60-year-old patient developed recurrent non-ST-segment elevation myocardial infarctions for 1 year. After an initial coronary angiogram that was normal, serial angiograms showed de novo aneurysm formation. The patient responded favorably to corticosteroids, supporting the diagnosis of isolated coronary arteritis. (Level of Difficulty: Intermediate.).

RESUMO

Introduction and Objectives: Center-based cardiac rehabilitation (CR) programs have been forced to close due to COVID-19. Alternative delivery models to maintain access to CR programs and to avoid physical inactivity should be considered. The aim of this study was to assess physical activity (PA) levels after completing a home-based digital CR program. Methods: A total of 116 cardiovascular disease (CVD) patients (62.6±8.9 years, 95 male) who had been attending a face-to-face CR program were recruited and assessed (baseline and at three months) on the following parameters: PA, sedentary behavior, adherence, cardiovascular and non-cardiovascular symptoms, feelings toward the pandemic, dietary habits, risk factor control, safety and adverse events. The intervention consisted of a multidisciplinary digital CR program, including regular patient assessment, and exercise, educational and psychological group sessions. Results: Ninety-eight CVD patients successfully completed all the online assessments (15.5% drop-out rate). A favorable main effect of time was an increase in moderate to vigorous PA and a decrease in sedentary time at three months. Almost half of the participants completed at least one online exercise training session per week and attended at least one of the online educational sessions. No major adverse events were reported and only one minor event occurred. Conclusion: During the pandemic, levels of moderate to vigorous PA improved after three months of home-based CR in CVD patients with previous experience in a face-to-face CR model. Diversified CR programs with a greater variety of content tailored to individual preferences are needed to meet the motivational and clinical requirements of CVD patients.


Introdução e objetivos: Os programas convencionais de reabilitação cardíaca (RC) foram forçados a encerrar devido à Covid-19. Modelos alternativos para que os doentes tenham acesso a um programa de RC evitando a inatividade física devem ser considerados. O objetivo deste estudo foi avaliar os níveis de atividade física (AF) de um programa digital de RC em casa. Métodos: Foram recrutados e avaliados (inicialmente e aos três meses) 116 doentes cardiovasculares (CV) (62,6±8,9 anos, 95 homens) que frequentavam um programa presencial de RC, nos seguintes parâmetros: AF, comportamento sedentário, adesão, sintomas CV e não CV, sentimentos face à pandemia, hábitos alimentares, fatores de risco, segurança e eventos adversos. A intervenção consistiu num programa digital multidisciplinar de RC, inclusive acompanhamento regular, sessões de exercício, de ensino e de psicologia em grupo. Resultados: Completaram com sucesso todas as avaliações online (15,5% drop-out) 98 pessoas com doença CV. Houve um efeito favorável no aumento da AF moderada a vigorosa e diminuição do tempo sedentário aos três meses. Quase metade da amostra fez, pelo menos, mais de uma sessão de exercício físico online por semana e assistiu a pelo menos uma das sessões educacionais online. Não se verificaram eventos major e registou-se apenas um minor. Conclusão: Em tempo de pandemia, os níveis de AF moderada a vigorosa melhoraram após três meses em doentes CV que frequentavam previamente um modelo presencial de RC. São necessários mais programas de RC com maior variedade de conteúdos adaptados à preferência individual para dar resposta às necessidades motivacionais e clínicas dos doentes CV.

RESUMO

Hemophilia A is an inherited coagulation disease characterized by factor VIII (FVIII) deficiency and is associated with high hemorrhagic risk, especially in its severe forms. As the average life expectancy of patients with hemophilia has increased, so has the prevalence of acute coronary events. There is however limited experience in dealing with them. The strategy of acting on acute coronary events in patients with hemophilia, as demonstrated in the present case, is a real challenge, not only due to the need for antiplatelet therapy (which is essential in the prevention of stent thrombosis, but increases hemorrhagic risk), but also due to the lack of specific recommendations related to the most adequate and safe replacement therapy in these situations. The authors describe the case of a 48-year-old man with unstable angina and a previous diagnosis of severe hemophilia A who underwent percutaneous coronary intervention under FVIII therapy without hemorrhagic complications.

RESUMO

BACKGROUND: Cognitive impairment, anxiety and depression are common in heart failure (HF) patients and its evolution is not fully understood. OBJECTIVES: To assess the cognitive status of HF patients over time, its relation to anxiety and depression, and its prognostic impact. METHODS: Prospective, longitudinal, single center study including patients enrolled in a structured program for follow-up after hospital admission for HF decompensation. Cognitive function, anxiety/depression state, HF-related quality of life (QoL) were assessed before discharge and during follow-up (between 6th and 12th month) using Montreal Cognitive Assessment (MoCA), Hospital Anxiety and Depression Scale (HADS) and Kansas City Cardiomyopathy Questionnaire, respectively. HF related outcomes were all cause readmissions, HF readmissions and the composite endpoint of all-cause readmissions or death. RESULTS: 43 patients included (67±11.3 years, 69% male); followed-up for 8.2±2.1 months. 25.6% had an abnormal MoCA score that remained stable during follow-up (22.6±4.2 vs. 22.2±5.5; p=NS). MoCA score <22 at discharge conferred a sixfold greater risk of HF readmission [HR=6.42 (1.26-32.61); p=0.025], also predicting all-cause readmissions [HR=4.00 (1.15-13.95); p=0.03] and death or all-cause readmissions [HR=4.63 (1.37-15.67); p=0.014]. Patients with higher MoCA score showed a greater ability to deal with their disease (p=0.038). At discharge, 14% and 18.6% had an abnormal HADS score for depression and anxiety, respectively, which remained stable during follow-up and was not related to MoCA. CONCLUSIONS: Cognitive function, anxiety and depressive status remain stable in HF patients despite optimized HF therapy. Cognitive status shall be routinely screened to adopt attitudes that improve management as it has an impact on HF-related QoL and prognosis.

RESUMO

BACKGROUND: Cardiac resynchronization therapy demonstrated benefits in heart failure. However, only 60-70% are responders and only 22% are super-responders. MultiPoint pacing (MPP) improves structural remodeling, but data in responder patients is scarce. METHODS: A prospective, randomized study of the efficacy of MPP was conducted in patients who were CRT responders after 6 months of bi-ventricular (BiV) therapy. At 6 months, responder patients (LV end-systolic volume [LVESV] reduction ≥15%) were randomized to either continued BiV therapy or to MPP programmed with wide anatomical separation ≥30 mm, and followed until 12 months. Efficacy was determined by 6-12 month changes in LVESV and LV ejection fraction (LVEF). Evaluations of super-responder rate (LVESV reduction ≥30%) and quality of life (NYHA, EQ-5D, MLHFQ) were also performed. RESULTS: From February 2017 to February 2019, 73 CRTs with Quartet LV leads were implanted (42.9% female, 65.7 ± 10.8 years old, 79.5% dilated cardiomyopathy). At 6 months, 74.2% responded to BiV and were randomized to BiV (n = 25) or MPP (n = 24). MPP versus BiV delivered greater LVESV improvement (8.3% decrease in MPP vs. 10.3% increase in BiV patients, p = .047), greater increase in LVEF (7.7% vs. 1.8%, p = .008), and higher 0-12 month super-responder rate (86.4% vs. 56.0%, p = .027). More MPP vs. BiV patients experienced an improvement in NYHA (84.6% vs. 50.0%, p = .047) and EQ-5D (94.4% vs. 54.0%, p = .006). CONCLUSIONS: MPP with wide anatomical spacing in CRT responder patients resulted in improved LV reverse remodeling with higher rates of super-responders, and better quality of life metrics.

RESUMO

OBJECTIVE: To identify predictors of coronary artery disease in survivors of cardiac arrest, to define the best timing for coronary angiography and to establish the relationship between coronary artery disease and mortality. METHODS: This was a single-center retrospective study including consecutive patients who underwent coronary angiography after cardiac arrest. RESULTS: A total of 117 patients (63 ± 13 years, 77% men) were included. Most cardiac arrest incidents occurred with shockable rhythms (70.1%), and the median duration until the return of spontaneous circulation was 10 minutes. Significant coronary artery disease was found in 68.4% of patients, of whom 75% underwent percutaneous coronary intervention. ST-segment elevation (OR 6.5, 95%CI 2.2 - 19.6; p = 0.001), the presence of wall motion abnormalities (OR 22.0, 95%CI 5.7 - 84.6; p < 0.001), an left ventricular ejection fraction ≤ 40% (OR 6.2, 95%CI 1.8 - 21.8; p = 0.005) and elevated high sensitivity troponin T (OR 3.04, 95%CI 1.3 - 6.9; p = 0.008) were predictors of coronary artery disease; the latter had poor accuracy (area under the curve 0.64; p = 0.004), with an optimal cutoff of 170ng/L. Only ST-segment elevation and the presence of wall motion abnormalities were independent predictors of coronary artery disease. The duration of cardiac arrest (OR 1.015, 95%CI 1.0 - 1.05; p = 0.048) was an independent predictor of death, and shockable rhythm (OR 0.4, 95%CI 0.4 - 0.9; p = 0.031) was an independent predictor of survival. The presence of coronary artery disease and the performance of percutaneous coronary intervention had no impact on survival; it was not possible to establish the best cutoff for coronary angiography timing. CONCLUSION: In patients with cardiac arrest, ST-segment elevation, wall motion abnormalities, left ventricular dysfunction and elevated high sensitivity troponin T were predictive of coronary artery disease. Neither coronary artery disease nor percutaneous coronary intervention significantly impacted survival.


OBJETIVO: Identificar os preditores de doença arterial coronária em sobreviventes à parada cardíaca, visando definir o melhor momento para realização de angiografia coronária e estabelecer o relacionamento entre doença arterial coronária e mortalidade. MÉTODOS: Este foi um estudo retrospectivo em centro único, que incluiu os pacientes consecutivamente submetidos à angiografia coronária após uma parada cardíaca. RESULTADOS: Incluímos 117 pacientes (63 ± 13 anos, 77% homens). A maioria dos incidentes de parada cardíaca ocorreu com ritmos chocáveis (70,1%), e o tempo mediano até retorno da circulação espontânea foi de 10 minutos. Identificou-se doença arterial coronária em 68,4% dos pacientes, dentre os quais 75% foram submetidos à intervenção coronária percutânea. Elevação do segmento ST (RC de 6,5; IC95% 2,2 - 19,6; p = 0,001), presença de alterações da contratilidade segmentar (RC de 22,0; IC95% 5,7 - 84,6; p < 0,001), fração de ejeção ventricular esquerda ≤ 40% (RC de 6,2; IC95% 1,8 - 21,8; p = 0,005) e níveis elevados de troponina T de alta sensibilidade (RC de 3,04; IC95% 1,3 - 6,9; p = 0,008) foram preditores de doença arterial coronária; esse último teve baixa precisão (área sob a curva de 0,64; p = 0,004), tendo o nível de 170ng/L como ponto ideal de corte. Apenas elevação do segmento ST e presença de alterações da contratilidade segmentar foram preditores independentes de doença arterial coronária. A duração da parada cardíaca (RC de 1,015; IC95% 1,0 - 1,05; p = 0,048) foi um preditor independente de óbito, e ritmo chocável (RC de 0,4; IC95% 0,4 - 0,9; p = 0,031) foi um preditor independente de sobrevivência. A presença de doença arterial coronária e a realização de intervenção coronária percutânea não tiveram impacto na sobrevivência; não foi possível estabelecer o melhor ponto de corte para o momento da angiografia coronária. CONCLUSÃO: Em pacientes com parada cardíaca, elevação do segmento ST, alterações da contratilidade segmentar, disfunção ventricular esquerda e níveis elevados de troponina T de alta sensibilidade foram preditivos de doença arterial coronária. Nem doença arterial coronária nem a intervenção coronária percutânea tiveram impacto significante na sobrevivência.

RESUMO

AIMS: Non-invasive telemonitoring (TM) in patients with heart failure (HF) and reduced left ventricular ejection fraction (HFrEF) may be useful in the early diagnosis of HF decompensation, allowing therapeutic optimization and avoiding re-hospitalization. We describe a TM programme in this population and evaluate its effectiveness during a 12 month period. METHODS AND RESULTS: We conducted a single-centre study of patients discharged from hospital after decompensated HF, allocated into three groups: prospective TM programme, prospective HF protocol follow-up programme (PFP) with no TM facilities, and retrospective propensity-matched usual care (UC). TM effectiveness was assessed by all-cause hospitalizations and mortality; HF-related hospitalization (HFH), days lost to unplanned hospital admissions/death, functional capacity and quality of life (New York Heart Association, Kansas City Cardiomyopathy Questionnaire, 6 min walk test, and plasma N-terminal pro-brain natriuretic peptide) were also evaluated. A total of 125 patients were included [65.9 ± 11.9 years, 32% female, left ventricular ejection fraction 27% (21-32)]. TM was similar to PFP regarding effectiveness; TM reduced all-cause hospitalization and mortality (HR 0.27; 95% CI 0.11-0.71; P < 0.01) and HFH (HR 0.29; 95% CI 0.10-0.89; P < 0.05) as compared with UC. TM reduced the average number of days lost due to unplanned hospital admissions or all-cause death as compared with PFP (5.6 vs. 12.4 days, P < 0.05) and UC (5.6 vs. 48.8 days, P < 0.01). Impact on quality of life was similar between TM and PFP (P = 0.36). CONCLUSIONS: In patients with HFrEF and recent HF hospitalization, non-invasive TM reduced 12 month all-cause hospitalization/mortality and HFH as compared with usual care. TM also reduced the number of days lost due to unplanned hospital admission/death as compared with either an optimized protocol-based follow-up programme or usual care.

RESUMO

BACKGROUND: Left ventricular (LV) lead placement is the most challenging aspect of cardiac resynchronization therapy (CRT) device implantation, with a failure rate of up to 10% due to complex coronary anatomies. We describe a modified snare technique for LV lead placement and evaluate its safety and efficacy in cases when standard methods fail. METHODS AND RESULTS: A prospective study was conducted of patients indicated for a CRT implant. When LV lead delivery to the target vessel failed using standard techniques, a modified snare technique was employed. Patients were evaluated every 6 months. From 2015 to 2019, 566 CRTs were implanted (26.1% female, 72 ± 10.2 years old, follow-up duration 18.9 ± 15.8 months). The standard LV implant technique failed in 94 cases (16.6%), of which the modified snare technique was successful in 92 (97.9%). There were no differences between the modified snare and standard techniques in the rates of 30-day postimplant CRT all-cause mortality (3.2% vs. 1.7%, p = .33), 4-year all-cause mortality (15.9% vs. 15.5%, p = .49), or major acute complications (7.4% vs. 3.8%, p = .12). However, the 4-year procedural reintervention rate was lower with the modified snare technique (3.2% vs. 10.2%, p < .05), specifically LV implant failure or dislodgement rates (0% vs. 5.3%, p < .05), improving the response rate (71.8% vs. 55.1%, p < .05). CONCLUSIONS: For challenging coronary sinus anatomies that preclude LV lead placement by standard methods, this modified snare alternative was safe and effective, with comparable mortality and complications, but significantly lower procedural reintervention and higher response rates.

RESUMO

INTRODUCTION: Patient selection for percutaneous coronary intervention (PCI) in chronic total occlusions (CTOs) is crucial to procedural success. Our aim was to identify independent predictors of success in CTO PCI in order to create an accurate score. METHODS: In a single-center observational registry of CTO PCI, demographic and clinical data and anatomical characteristics of coronary lesions were recorded. Linear and logistic regression analysis were used to identify predictors of success. A score to predict success was created and its accuracy was measured by receiver operating curve analysis. RESULTS: A total of 377 interventions were performed (334 patients, age 68±11 years, 75% male). The success rate was 65% per patient and 60% per procedure. Predictors of success in univariate analysis were absence of active smoking (OR 2.02, 95% CI 1.243-3.29; p=0.005), presence of tapered stump (OR 5.2, 95% CI 2.7-10.2; p<0.001), absence of tortuosity (OR 6.44; 95% CI 3.02-13.75; p<0.001), absence of bifurcation (OR 1.95; 95% CI 1.08-3.51; p=0.026), absence of calcification (OR 3.1; 95% CI 3.10-5.41; p<0.001), LAD as target vessel (OR 1.9, 95% CI 1.0-3.5; p=0.048), and CTO length <20 mm (OR 3.00, 95% CI 1.69-5.3; p<0.001). Only anatomical factors were independent predictors of success, and an anatomical score (0-11 points) with high accuracy (area under the curve 0.831) was subsequently created. A score <3 was associated with low probability of success (15%), 3-8 with intermediate probability (55%), and >8 with high probability (95%). CONCLUSION: In our sample only anatomical characteristics were predictors of success. The creation of a score to predict success, with good accuracy, may enable selection of cases that can be treated by any operator, those in which a dedicated operator will be desirable, and those with an extremely low probability of success, which should be considered individually for conservative management, surgical revascularization or PCI by a team experienced in CTO.

RESUMO

OBJECTIVE: To evaluate the impact of the presence of sepsis on in-hospital mortality after intensive care unit discharge. METHODS: Retrospective, observational, single-center study. All consecutive patients discharged alive from the intensive care unit of Hospital Vila Franca de Xira (Portugal) from January 1 to December 31, 2015 (N = 473) were included and followed until death or hospital discharge. In-hospital mortality after intensive care unit discharge was calculated for septic and non-septic patients. RESULTS: A total of 61 patients (12.9%) died in the hospital after being discharged alive from the intensive care unit. This rate was higher among the patients with sepsis on admission, 21.4%, whereas the in-hospital, post-intensive care unit mortality rate for the remaining patients was nearly half that, 9.3% (p < 0.001). Other patient characteristics associated with mortality were advanced age (p = 0.02), male sex (p < 0.001), lower body mass index (p = 0.02), end-stage renal disease (p = 0.04) and high Simplified Acute Physiology Score II (SAPS II) at intensive care unit admission (p < 0.001), the presence of shock (p < 0.001) and medical admission (p < 0.001). We developed a logistic regression model and identified the independent predictors of in-hospital mortality after intensive care unit discharge. CONCLUSION: Admission to the intensive care unit with a sepsis diagnosis is associated with an increased risk of dying in the hospital, not only in the intensive care unit but also after resolution of the acute process and discharge from the intensive care unit.


OBJETIVO: Avaliar o impacto da presença de sepse na mortalidade hospitalar após alta da unidade de terapia intensiva. MÉTODOS: Ensaio retrospectivo, observacional, em centro único. Todos os pacientes que consecutivamente receberam alta vivos da unidade de terapia intensiva do Hospital Vila Franca de Xira (Portugal) entre 1º de janeiro e 31 de dezembro de 2015 (N = 473) foram incluídos e acompanhados até o óbito ou alta do hospital. A mortalidade hospitalar após alta da unidade de terapia intensiva foi calculada para pacientes sépticos e não sépticos. RESULTADOS: Um total de 61 pacientes (12,9%) faleceu no hospital após receber alta vivos da unidade de terapia intensiva. Esta taxa foi mais elevada entre os pacientes que tinham sepse quando da admissão (21,4%), enquanto a taxa de mortalidade hospitalar após alta da unidade de terapia intensiva para os demais pacientes foi aproximadamente a metade (9,3%), com p < 0,001. Outras características dos pacientes associadas com mortalidade foram idade avançada (p = 0,02), sexo masculino (p < 0,001), índice mais baixo de massa corporal (p = 0,02), nefropatia terminal (p = 0,04) e, quando da admissão à unidade de terapia intensiva, escore elevado segundo o Simplified Acute Physiology Score (SAPS II); p < 0,001, presença de choque (p < 0,001) e admissão por causas clínicas (p < 0,001). Desenvolvemos um modelo de regressão logística e identificamos os preditores independentes de mortalidade hospitalar após alta da unidade de terapia intensiva. CONCLUSÃO: A admissão à unidade de terapia intensiva com diagnóstico de sepse se associa com maior risco de morrer no hospital, não apenas na unidade de terapia intensiva quanto também após a resolução do processo agudo e alta da unidade de terapia intensiva.

ABSTRACT Objective: To evaluate the impact of the presence of sepsis on in-hospital mortality after intensive care unit discharge. Methods: Retrospective, observational, single-center study. All consecutive patients discharged alive from the intensive care unit of Hospital Vila Franca de Xira (Portugal) from January 1 to December 31, 2015 (N = 473) were included and followed until death or hospital discharge. In-hospital mortality after intensive care unit discharge was calculated for septic and non-septic patients. Results: A total of 61 patients (12.9%) died in the hospital after being discharged alive from the intensive care unit. This rate was higher among the patients with sepsis on admission, 21.4%, whereas the in-hospital, post-intensive care unit mortality rate for the remaining patients was nearly half that, 9.3% (p < 0.001). Other patient characteristics associated with mortality were advanced age (p = 0.02), male sex (p < 0.001), lower body mass index (p = 0.02), end-stage renal disease (p = 0.04) and high Simplified Acute Physiology Score II (SAPS II) at intensive care unit admission (p < 0.001), the presence of shock (p < 0.001) and medical admission (p < 0.001). We developed a logistic regression model and identified the independent predictors of in-hospital mortality after intensive care unit discharge. Conclusion: Admission to the intensive care unit with a sepsis diagnosis is associated with an increased risk of dying in the hospital, not only in the intensive care unit but also after resolution of the acute process and discharge from the intensive care unit.

RESUMO

INTRODUCTION: Transcatheter aortic valve implantation has emerged as an effective alternative to the traditional method of surgical aortic valve replacement in high risk or inoperable patients. Infective endocarditis after transcatheter aortic valve implantation is a post-operative complication with a high rate of mortality, and thus far, very few cases of successful surgery have been reported. CASE PRESENTATION: The authors report the case of a patient that underwent transcatheter aortic valve implantation and developed an infective endocarditis following the procedure. Corrective surgery for transcatheter aortic valve's removal and aortic valve replacement was successfully performed. CONCLUSIONS: Given the increasing use of transcatheter aortic valve implantation, endocarditis will become increasingly relevant in the near future. As in conventional aortic prosthesis, for some cases, medical therapy alone is not enough. Under optimal conditions, surgery is a safe option and should be considered and discussed in a Heart Team, patient by patient.

RESUMO

BACKGROUND: Omalizumab is a humanized monoclonal anti-immunoglobulin E antibody, approved for the treatment of spontaneous chronic urticaria, with high efficacy and an excellent safety profile. Although its adverse effects are rare, allergic reactions and cardiovascular events were previously described. CASE SUMMARY: The authors describe the case of a 75-year-old woman, followed at the outpatient dermatology clinic due to spontaneous chronic urticaria, treated with omalizumab 300 mg every 4 weeks. After the 11th administration of omalizumab, the patient developed an episode of thoracalgia associated with electro- and echocardiographic abnormalities. Coronary angiogram excluded coronary artery disease, and left ventriculography demonstrated mid-apical akinesia and basal hyperkinesia, consistent with the Takotsubo syndrome (TS). DISCUSSION: Takotsubo syndrome was already reported in association with other monoclonal antibodies. However, to our knowledge, this is the first case of TS following the administration of omalizumab.

RESUMO

INTRODUCTION: Heart failure is associated with high rates of readmission and mortality, and there is a need for measures to improve outcomes. This study aims to assess the impact of the implementation of a protocol-based follow-up program for heart failure patients on readmission and mortality rates and quality of life. METHODS: A quasi-experimental study was performed, with a prospective registry of 50 consecutive patients discharged after hospitalization for acute heart failure. The study group was followed by a cardiologist at days 7-10 and the first, third, sixth and 12th month after discharge, with predefined procedures. The control group consisted of patients hospitalized for heart failure prior to implementation of the program and followed on a routine basis. RESULTS: No significant differences were observed between the two groups regarding mean age (67.1±11.2 vs. 65.8±13.4 years, p=0.5), NYHA functional class (p=0.37), or median left ventricular ejection fraction (27% [19.8-35.3] vs. 29% [23.5-40]; p=0.23) at discharge. Mean follow-up after discharge was similar (11±5.3 vs. 10.9±5.5 months, p=0.81). The protocol-based follow-up program was associated with a significant reduction in all-cause readmission (26% vs. 60%, p=0.003), heart failure readmission (16% vs. 36%, p=0.032), and mortality (4% vs. 20%, p=0.044). In the study group there was a significant improvement in all quality of life measures (p<0.001). CONCLUSION: A protocol-based follow-up program for patients with heart failure led to a significant reduction in readmission and mortality rates, and was associated with better quality of life.

RESUMO

INTRODUCTION: Valvular heart disease (VHD) is increasing worldwide, mostly because of aging. Percutaneous valve intervention is the preferred therapeutic option in high-risk patients. OBJECTIVE: To characterize the profiles of patients with VHD admitted to the cardiology ward at a tertiary referral center. METHODS: On the basis of ICD-9 codes for VHD, the discharge notes of 287 patients hospitalized over a 22-month period were reviewed and analyzed. One hundred characteristics were considered. RESULTS: Median age was 74 (23-93) years, and 145 (51%) were male. The admissions were elective (for valve intervention) in 36%. Heart failure (HF) was the reason for urgent admissions in 29.3%. Multiple comorbidities were observed in 53% of patients. Etiology of VHD was degenerative in 68%, functional in 15.3% and rheumatic (predominantly in women and younger patients) in 8.7%. Aortic valve disease was present in 63% (aortic stenosis in 56%), and was associated with HF (p=0.004), atrial fibrillation (AF) (p=0.01), and left ventricular (LV) dilatation (p=0.003) or hypertrophy (p<0.001). Mitral valve disease (51%), mostly mitral regurgitation (degenerative or functional), predominated in women, and was associated with HF, AF, LV dilatation (p<0.001) and reduced LV ejection fraction (p=0.003). Significant tricuspid regurgitation (34.8%) associated with the presence of previously implanted cardiac devices (p<0.001). Valve intervention (mostly transcatheter aortic valve implantation) was performed in 41% of patients. Mean length of hospital stay was 12±14.3 days and overall in-hospital mortality was 9.8%. CONCLUSIONS: Nowadays, the profiles of hospitalized patients with VHD are dominated by the elderly, with degenerative disease and multiple comorbidities, presenting with HF, AF and LV remodeling, who frequently undergo valve intervention, usually via a percutaneous approach. Mortality remains significant in this high-risk population.
