Background: Hypertension is a major risk factor for cardiovascular diseases and a critical public health issue globally. In Portugal, hypertension is common among older adults. Also, recent trends suggest that its prevalence may have changed over the last decade following the 2009 implementation of a public policy regulating the maximum amount of salt allowed in bread.
Objective: This systematic review and meta-analysis aimed to determine the prevalence of hypertension in Portugal across different age groups and genders, analyzing trends over the past two decades.
Methods: A systematic literature search was conducted using the PubMed and Cochrane databases, as well as additional sources including publications from the Statistics Portugal and the Portuguese National Health Institute. Population-based cross-sectional and cohort studies reporting the prevalence of hypertension among Portuguese adults, published between 2000-2020, were included. The overall prevalence of hypertension was estimated using a random effects meta-analysis model.
Results: The overall prevalence of hypertension in Portugal was 31% (95% confidence interval (CI): 25.0%-37%, I²: 99.80%), with a prevalence of 34% in men (95% CI: 24%-46%, I²: 99.74%) and 33% in women (95% CI: 28%-38%, I²: 98.72%). Studies that measured blood pressure reported a higher prevalence (38%, 95% CI: 33%-43%, I²: 97.75%) compared to self-reported hypertension (24%, 95% CI: 21%-27%, I²: 99.20%). A downward trend in prevalence was observed in more recently published studies, especially in adults aged <35 years (from 17%, 95% CI: 12%-22%, I²: 0.81%, to 6%, 95% CI: 5%-8%, I²: 0.01%), and in individuals ≥65 years old from both sexes (from 80%, 95% CI: 77%-84%, I²: 61.09%, to 73%, 95% CI: 70%-77%, I²: 63.69%).
Conclusion: Despite recent decreases, hypertension remains highly prevalent in Portugal, particularly among older adults. Self-reported data tend to underestimate the true prevalence of hypertension compared to blood pressure measurements.
Introduction and objectives: BTK inhibitors (BTKis) have revolutionized the treatment landscape of chronic lymphocytic leukemia (CLL). However, a higher risk of cardiovascular toxicity is reported among CLL patients treated with BTKis. This study aims to estimate the costs and consequences of cardiovascular toxicity associated with the different BTKis used for CLL treatment in Portugal.
Methods: The incidence rates and health-related outcomes consequences among CLL patients, including bleeding events, de novo atrial fibrillation (AF) and hypertension were retrieved from the literature for the different BTKis. Direct medical costs (payers' perspective) associated with diagnosis, monitoring and treatment of cardiovascular toxicity were calculated for one year. Inpatient costs were derived from the Portuguese Hospital Morbidity Database. Outpatient costs were estimated from an expert panel.
Results: Incidence rates per 100 CLL BTKis-treated patients ranged from 38.0 (acalabrutinib) to 70.3 (zanubrutinib) for bleeding, from 5.4 (zanubrutinib) to 14.9 (ibrutinib) for AF, and from 6.6 (acalabrutinib) to 36.7 (zanubrutinib) for hypertension. Incidence rates of health outcomes related to AF (stroke and heart failure) were higher among ibrutinib-treated patients, whereas health outcomes related to hypertension (angina, myocardial infarction, heart failure and peripheral arterial disease) were higher among zanubrutinib-treated patients. Total costs per 100 CLL BTKis-treated patients over the first year were EUR 38803.10, EUR 82,683.61, and EUR 86,084.56 for acalabrutinib, zanubrutinib, and ibrutinib, respectively. In subsequent years, costs decreased by 47%, 43%, and 39%, respectively.
Conclusion: The clinical and economic burden of cardiovascular toxicity associated with BTKis treatment among CLL patients is high, with ibrutinib showing the highest impact in comparison to the more selective BTKis.
Introduction and objectives: Cardiopulmonary exercise testing (CPET) provides relevant data in several clinical contexts. Although reports highlight its application across various moments of the cardiovascular continuum, from heart failure (HF) to the assessment of athletes, its implementation has been described as suboptimal. This study aimed to assess perspectives on CPET training and usage patterns among cardiologists in Portugal.
Methods: An online questionnaire divided into three parts (participant characteristics, training and application of CPET and knowledge assessment) was structured and sent to members of the Portuguese Society of Cardiology. The study population comprised physicians with a medical specialty in cardiology (specialists or residents from the second year onwards).
Results: 70 individuals (52.9% male, 57.1% ≤ 50 years-old) provided valid answers. Most (58.6%) had access to CPET in their workplace, while 65.7% reported using it in their clinical practice; HF was the most frequent indication for use. Just under half of participants (48.6%) had not dedicated or intended to dedicate time to CPET during residency, lack of access, interest, and time were the most frequently reported reasons. Less than half of those who participated in CPET exams during residency thought they had become proficient in its use. Most participants (97.1%) reported that specific training during residency could improve usage.
Conclusions: This survey provides up to date information on CPET implementation, highlighting challenges and areas of potential improvement, such as training and accessibility. These findings may provide a framework for optimizing the use of this key test in cardiovascular medicine.
Introduction and objectives: Implantable cardioverter-defibrillators (ICDs) are among the most effective interventions for the prevention of sudden cardiac death. However, traditional transvenous systems are associated with venous access and intracardiac lead complications. Subcutaneous ICDs (S-ICD), which were developed to overcome these complications, are unable to provide anti-tachycardia pacing (ATP) or pause prevention pacing. The extravascular ICD (EV-ICD) is a recent technological innovation designed to mitigate these limitations by enabling cardioversion, defibrillation and pacing without entering the central venous system. Our aim was to assess the initial experience with the new EV-ICD system, as a valid alternative to transvenous ICD and S-ICD, including patient selection, implantation technique, procedure feasibility and safety, functional parameters, and immediate clinical outcomes.
Methods: We conducted an observational study of all patients who underwent EV-ICD implantation between November 2024 and June 2025 at two centers. Demographic, clinical, imaging, pharmacologic and procedural data were analyzed.
Results: A total of 11 patients were included, with a mean age of 36.3 years (range 19-59); 27% were female. Main diagnoses included hypertrophic cardiomyopathy (n=3), left ventricular non-dilated cardiomyopathy (n=3), dilated cardiomyopathy (n=2), Brugada syndrome (n=1), polymorphic ventricular tachycardia (n=1) and arrhythmogenic right ventricular cardiomyopathy (n=1). There were no procedural or peri-procedural complications. The mean procedure duration ("skin-to-skin") was 68.2 minutes (range 60-78). Median fluoroscopy time was 3.9 minutes (range 2.5-6.2). Defibrillation threshold (DFT) testing was successful in all cases. During the follow-up, two patients received an inappropriate shock, one due to sinus tachycardia and the other due to oversensing of myopotentials.
Conclusions: Our initial experience with the EV-ICD confirms the feasibility and safety of the procedure. This novel system may offer an effective alternative for selected populations, especially young patients with extended life expectancy and high cumulative device exposure. The rate of inappropriate shocks remains a concern and improvements are required to reduce these events.
