Other independent predictors of CIN were contrast media volume/eGFR ratio, initial glucose level, UA and hs-CRP.
The main finding of this study is that increased oxidative stress and inflammation parameters were associated with the development of CIN in patients with STEMI. Other independent predictors of CIN were contrast media volume/eGFR ratio, initial glucose level, UA and hs-CRP.
Cancer chemotherapy increases the risk of heart failure. This cost-effectiveness study analyzes cardio-oncology imaging assessment of left ventricular ejection fraction (LVEF) using a Portuguese healthcare payer perspective and a five-year time horizon.

Two cardioprotective strategies were assessed universal cardioprotection (UCP) for all patients and cardioprotection initiated on diagnosis of LVEF-defined cardiotoxicity (EF-CTX). A Markov model, informed by the retrospective clinical course of breast cancer patients followed in a Portuguese public hospital, was developed to assess the cost-effectiveness of LVEF cardio-oncology imaging assessment. Data on transition probabilities, costs and utilities were retrieved from both the retrospective data and published literature to assess the cost-effectiveness of LVEF echocardiographic assessment. Costs and utilities of the cardioprotective strategies were assessed over a five-year range, using probabilistic sensitivity analyses.

In the reference case of a 63-year-old breast cancer patient treated with cardioprotection initiated on diagnosis of EF-CTX, the five-year time horizon (4.22 QALYs and €2594 cost over five years) dominated UCP (3.42 QALYS and €3758 cost over five years). Under a time horizon of five years at a willingness-to-pay threshold of €22 986, over 65.7% of simulations provided additional QALYs. Monte Carlo simulation of the Markov model had no effect on the model's conclusions.

In the Portuguese public healthcare system and under specific hypotheses, from a healthcare payer perspective, EF-CTX-guided cardioprotection for patients at risk of chemotherapy-related cardiotoxicity provides more QALYs at lower cost than UCP.

Coronavirus disease (COVID-19) has led to significant changes in healthcare systems and its impact on the treatment of cardiovascular conditions, such as ST-elevation myocardial infarction (STEMI), is unknown in countries where the healthcare systems were not saturated, as was the case in Portugal. As such, we aimed to assess the effect on STEMI admissions and outcomes in Portuguese centers.

We conducted a single-center, observational, retrospective study including all patients admitted to our hospital due to STEMI between the date of the first SARS-CoV-2 case diagnosed in Portugal and the end of the state of emergency (March and April 2020). Patient characteristics and outcomes were assessed and compared with the same period of 2019.

A total of 104 STEMI patients were assessed, 55 in 2019 and 49 in 2020 (-11%). There were no significant differences between groups regarding age (62±12 vs. 65±14 years, p=0.308), gender (84.8% vs. 77.6% males, p=0.295) or comorbidities. In the 2020 group, there was a signify these results and should be the target of future actions in further waves of the pandemic.
Despite a lack of significant variation in the absolute number of STEMI admissions, there was an increase in STEMI clinical severity and significantly worse outcomes during the SARS-CoV-2 pandemic. An increase in system delay, impaired pre-hospital care and patient fear of in-hospital infection can partially justify these results and should be the target of future actions in further waves of the pandemic.Myocardial infarction is very rare in children. It can have different etiologies such as thromboembolism caused by nephrotic syndrome (NS). We report the case of a 15 year old boy with NS, diagnosed at the age of 7 year, admitted for prolonged chest pain. The final diagnosis was ST-elevation myocardial infarction with thromboembolism in the left anterior descending artery due to hypercoagulability of NS. buy Poly-D-lysine This association is very uncommon and the management of both conditions presents a challenge.Cardiovascular diseases (CVD) are the most common cause of death worldwide. Among CVDs, heart failure (HF) is known to be the most common cause of hospitalization in patients over 65. Despite all proposed treatments for CVDs, mortality and morbidity still remain high. There are controversial reports available on vitamin D efficacy in patients with HF. In this systematic review and meta-analysis, we aimed to investigate whether vitamin D is effective at enhancing ejection fraction (EF) in patients with HF. We performed a systematic search across different databases (PubMed, SCOPUS, Web of Science, EMBASE, SciELO and Google Scholar) up to 1 Jan 2020 without any language or location limitations. Our suggested Population/Intervention/Comparison/Outcome/Type of study (PICOT) was P patients with HF, I vitamin D, C placebo or no treatment, O EF and T clinical trials. To achieve the highest sensitivity, only keywords associate with P and I were selected for the search query. A total number of 5397 primary studies were found, of which 13 were elected for data synthesis. Clinical trials were published and available since 2005 up to 2019 and a total number of 1215 patients were included. Our results showed that vitamin D can significantly enhance left ventricular EF in HF patients by 3.304% (95% confidence interval [CI] 0.954, 5.654, p=0.006). Based on our observations, we conclude that before conducting a large number of high quality clinical trials and further meta-analysis, vitamin D should be prescribed to all patients with HF.
Catheter ablation has been shown to improve left ventricular (LV) ejection fraction (LVEF) in patients with atrial fibrillation (AF) and heart failure (HF). Our aim was to assess the impact of AF ablation on the outcome of patients with HF and LV systolic dysfunction.

We performed a retrospective observational cohort study of all patients with HF and LVEF <50% and with no apparent cause for systolic dysfunction other than AF who underwent catheter ablation in a tertiary referral center between July 2016 and November 2018. The primary endpoint was a ≥5% improvement in LVEF. Secondary endpoints included improvement in New York Heart Association (NYHA) class and reduction in LV end-diastolic diameter (LVEDD) and left atrial diameter (LAD).

Of 153 patients who underwent AF ablation in this period, 22 (77% male, median age 61 [IQR 54-64] years) fulfilled the inclusion criteria. Median follow-up was 11.1 months (IQR 6.1-19.0). After ablation, median LVEF increased from 40% (IQR 33-41) to 58% (IQR 55-62) (p<0.01), mean NYHA class improved from 2.35±0.49 to 1.3±0.47 (p<0.001), and median LAD and LVEDD decreased from 48.0 (IQR 43.5-51.5) mm to 44 (IQR 40-49) mm (p<0.01) and from 61.0 (IQR 54.0-64.8) mm to 55.0 (52.2-58.0) mm (p<0.01), respectively.

In patients with HF and LV systolic dysfunction, AF ablation is associated not only with improved functional status but also with favorable structural remodeling, including improvement in LVEF and decreases in LAD and LVEDD.

Our goal was to assess usefulness of Pattern Matching Filter (PMF) software combined with the PentaRay catheter for complex premature ventricular contraction (PVC) ablation.

A prospective observational study of consecutive patients referred for complex PVC ablation at our tertiary center from January to September 2018. Patients underwent ablation using a pre-specified mapping strategy with the PMF and the PentaRay catheter (PVCs with ≥97% correlation with the template morphology were collected). Procedural endpoints and acute and 12-months success rates were assessed and compared to a retrospective cohort of patients who also underwent a complex PVC ablation with standard activation mapping performed with a Thermocool SmartTouch catheter.

During the nine-month enrollment period, seven patients fulfilled our inclusion criteria, while there were four patients in the control group. Patients treated with the PMF and PentaRay had a fivefold number of points acquired (507±213 vs. 90±62) and a halved procedureoved outcomes.
Cardiovascular disease is the leading cause of death in Portugal and atherosclerosis is the most common underlying pathophysiological process. The aim of this study was to quantify the economic impact of atherosclerosis in Portugal by estimating disease-related costs.

Costs were estimated based on a prevalence approach and following a societal perspective. Three national epidemiological sources were used to estimate the prevalence of the main clinical manifestations of atherosclerosis. The annual costs of atherosclerosis included both direct costs (resource consumption) and indirect costs (impact on population productivity). These costs were estimated for 2016, based on data from the Hospital Morbidity Database, the health care database (SIARS) of the Regional Health Administration of Lisbon and Tagus Valley including real-world data from primary care, the 2014 National Health Interview Survey, and expert opinion.

The total cost of atherosclerosis in 2016 reached 1.9 billion euros (58% and 42% of which was direct and indirect costs, respectively). Most of the direct costs were associated with primary care (55%), followed by hospital outpatient care (27%) and hospitalizations (18%). Indirect costs were mainly driven by early exit from the labor force (91%).

Atherosclerosis has a major economic impact, being responsible for health expenditure equivalent to 1% of Portuguese gross domestic product and 11% of current health expenditure in 2016.

Studies assessing the effects of caffeine (CAF) on the cardiovascular system have demonstrated that CAF can delay cardiac recovery following exercise. This study intended to assess the impact of CAF intake before physical exercise on heart rate variability (HRV) and cardiovascular parameters.

This is a prospective, crossover, controlled clinical trial conducted at the University of Pernambuco, Petrolina, PE, Brazil. The experimental protocol was split into three stages with a minimum of 48 hours between them. Exercises intensity was standardized based on the one repetition maximum test (1RM), obtaining the load of each volunteer for the intensity of 75% of 1RM. In the second and third phases, the control protocols were applied and 300 mg caffeine was given 45 minutes before training. HRV indices were determined at the subsequent times 0 to 5 minutes of rest (before) and during 30 minutes of recovery (Rec) (after exercise), divided into six intervals, each of 5 minutes.

The final sample involved 30 volunteers.
