RESUMO

There are scarce data on the comparative prognosis between patients with hypertensive emergencies (HE), urgencies (HU), and those without HU or HE (HP). Our study aimed to compare cardiovascular (CV) outcomes of HE, HU, and HP during a 12-month follow-up period. The population consisted of 353 consecutive patients presenting with HE or HU in a third-care emergency department and subsequently referred to our hypertension center for follow-up. After both groups completed scheduled follow-up visits, patients with HU were matched one-to-one by age, sex, and hypertension history with HP who attended our hypertension center during the same period. Primary outcomes were 1) a recurrent hypertensive HU or HE event and 2) non-fatal CV events (coronary heart disease, stroke, heart failure, or CV interventions), while secondary outcomes were 1) all-cause death, 2) CV death, 3) non-CV death, and 4) any-cause hospitalization. Events were prospectively registered for all three groups. During the study period, 81 patients were excluded for not completing follow-up. Among eligible patients(HE = 94; HU = 178), a total of 90 hospitalizations and 14 deaths were recorded; HE registered greater CV morbidity when compared with HU (29 vs. 9, HR 3.43, 95 % CI 1.7-6.9, p = 0.001), and increased CV mortality (8 vs. 1, HR 13.2, 95 % CI 1.57-110.8, p = 0.017). When opposing HU to HP, events did not differ substantially. Cox regression models were adjusted for age, sex, CV and chronic kidney disease, diabetes mellitus, and smoking. During 1-year follow-up, the prognosis of HU was better than HE but not different compared to HP. These results highlight the need for improved care of HU and HE.

RESUMO

Sleep disordered breathing (SDB), mostly constituting of obstructive and central sleep apnea (OSA and CSA, respectively), is highly prevalent in the general population, and even more among patients with cardiovascular disease, heart failure (HF) and valvular heart disease, such as mitral regurgitation (MR). The coexistence of HF, MR and SDB is associated with worse cardiovascular outcomes and increased morbidity and mortality. Pulmonary congestion, as a result of MR, can exaggerate and worsen the clinical status and symptoms of SDB, while OSA and CSA, through various mechanisms that impair left ventricular dynamics, can promote left ventricular remodelling, mitral annulus dilatation and consequently MR. Regarding treatment, positive airway pressure devices used to ameliorate symptoms in SDB also seem to result in a reduction of MR severity, MR jet fraction and an improvement of left ventricular ejection fraction. However, surgical and transcatheter interventions for MR, and especially transcatheter edge to edge mitral valve repair (TEER), seem to also have a positive effect on SDB, by reducing OSA and CSA-related severity indexes and improving symptom control. The purpose of this review is to provide a comprehensive analysis of the common pathophysiology between SDB and MR, as well as to discuss the available evidence regarding the effect of SDB treatment on MR and the effect of mitral valve surgery or transcatheter repair on both OSA and CSA.

RESUMO

Current evidence on the prognosis of patients with a hypertensive crisis and predisposing factors is limited. We registered the clinical phenotype of patients with HC admitted to the emergency department, while those with a hypertensive emergency (HE) were hospitalized. One-year outcomes, i.e., composite of death or cardiovascular hospitalizations, were determined in patients with HE after hospital discharge. Out of 38,589 patients assessed in the emergency department, 256 hypertensive urgencies and 97 HE was registered. After stratification of the HE by sex, 48 men and 46 women completed the one-year follow-up. Men had more events than women (27 vs. 13, Ηazard Ratio 2.2, 95% Confidence Interval 1.03-4.7, p = 0.042) after adjustment for age, cardiovascular or chronic kidney disease, and diabetes mellitus. Our study raises the hypothesis that the male sex is an independent risk factor for cardiovascular outcomes in HE patients. CV Cardiovascular, BP blood pressure. The diagram presents the groups of comparison, men versus women in hypertensive emergencies that completed the 1-year follow-up for outcomes, in terms of hospitalizations or deaths.

RESUMO

Acute tobacco cigarette (TC) smoking increases blood pressure and sympathetic nerve activity, whereas there are scarce data on the impact of electronic cigarette (EC) smoking. We assessed the acute effects of TC, EC and sham smoking on blood pressure, heart rate and sympathetic nervous system. Methods: We studied 12 normotensive male habitual smokers (mean age 33 years) free of cardiovascular disease. The study design was randomized and sham controlled with three experimental sessions (sham smoking, TC smoking and EC smoking). After baseline measurements at rest, the subjects were then asked to smoke (puffing habits left uncontrolled) two TC cigarettes containing 1.1 mg nicotine, EC smoking or simulated smoking with a drinking straw with a filter (sham smoking), in line with previous methodology. Results: EC smoking at 5 and 30 min compared to baseline was accompanied by the augmentation of mean arterial pressure (MAP) and heart rate (p < 0.001 for all). The muscle sympathetic nerve activity (MSNA) decrease was significant during both TC and EC sessions (p < 0.001 for both comparisons) and was similar between them (−25.1% ± 9.8% vs. −34.4% ± 8.3%, respectively, p = 0.018). Both MSNA decreases were significantly higher (p < 0.001 for both comparisons) than that elicited by sham smoking (−4.4% ± 4.8%). Skin sympathetic nerve activity increase was significant in both TC and EC groups (p < 0.001 for both comparisons) and similar between them (73.4% ± 17.9% and 71.9% ± 7%, respectively, p = 0.829). Conclusions: The unfavorable responses of sympathetic and arterial pressure to EC smoking are similar to those elicited by TC in healthy habitual smokers.

RESUMO

Anticoagulation therapy is the cornerstone of treatment in acute vein thrombosis (DVT) and it aims to reduce symptoms, thrombus extension, DVT recurrences, and mortality. The treatment for DVT depends on its anatomical extent, among other factors. Anticoagulation therapy for proximal DVT is clearly recommended (at least for 3 months), while AT for isolated distal DVT should be considered, especially in the presence of high thromboembolic risk factors. The optimal anticoagulant and duration of therapy are determined by the clinical assessment, taking into account the thromboembolic and bleeding risk in each patient in a case-by-case decision making. Non-Vitamin K antagonists oral anticoagulants (NOACs) were a revolution in the anticoagulation management of DVT. Nowadays, NOACs are considered as first-line therapy in the anticoagulation therapy for DVT and are recommended as the preferred anticoagulant agents by most scientific societies. NOACs offer a simple route of administration (oral agents), a rapid onset-offset of their action along with a good efficacy and safety profile in comparison with Vitamin K Antagonists (VKAs). However, there are issues about their efficacy and safety profile in specific populations with high thromboembolic and bleeding risks, such as renal failure patients, active-cancer patients, and pregnant women, in which VKAs and heparins were the standard care of treatment. Since the available data are promising for the use of NOACs in end-stage chronic kidney disease and cancer patients, several ongoing randomized trials are currently trying to solve that issues and give evidence about the safety and efficacy of NOACs in these populations.

RESUMO

Major cardiovascular (CV) outcome trials with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are currently available. These agonists have proven their CV safety, in harmony with the US Food and Drug Administration (FDA) recommendation for antidiabetic drugs. The potential cardioprotective effect of incretin-based therapies is attributed to their multiple non-glycaemic actions in the CV system, including changes in insulin resistance, weight loss, reduction in blood pressure, improved lipid profile and direct effects on the heart and vascular endothelium. Liraglutide, semaglutide and albiglutide have been demonstrated to reduce the risk of major adverse cardiac events (MACE), whereas lixisenatide and extended-release exenatide had a neutral effect. Thus, it is conceivable that there are different drug-specific properties across the class of GLP-1 RAs. In this review, we discuss the results of the five recently published randomised CV outcome trials with GLP-1 RAs, along with the potential differences and the pleiotropic actions of these agents on the CV system.
